YeonGyu-Kim c2beffe0e8 fix(#169): classify invalid/missing CLI flag values as cli_parse
Pinpoint #169: typed-error classifier gap discovered during dogfood probe.

`claw --output-format json --output-format xml doctor` was emitting:
  {"error": "unsupported value for --output-format: xml ...",
   "hint": null,
   "kind": "unknown",
   "type": "error"}

After fix:
  {"error": "unsupported value for --output-format: xml ...",
   "hint": "Run `claw --help` for usage.",
   "kind": "cli_parse",
   "type": "error"}

The change adds two new classifier branches to `classify_error_kind`:
1. `unsupported value for --` → cli_parse
2. `missing value for --` → cli_parse

Covers all `CliOutputFormat::parse` / `parse_permission_mode_arg` rejections
and any future flag-value validation messages using the same pattern.

Side benefit: the #247 hint synthesizer ("Run `claw --help` for usage.")
now triggers automatically because the error is now correctly classified
as cli_parse. Consumers get both correct kind AND helpful hint.

Test added:
- `classify_error_kind_covers_flag_value_parse_errors_169` (4 positive +
  1 sanity case)

Tests: 224/224 pass (+1 from #169).

YeonGyu-Kim 6a01c1a090 docs(#155): add missing slash command documentation to USAGE.md
Pinpoint #155: USAGE.md was missing documentation for three interactive
commands that appear in `claw --help`:
- /ultraplan [task]
- /teleport <symbol-or-path>
- /bughunter [scope]

Also adds full documentation for other underdocumented commands:
- /commit, /pr, /issue, /diff, /plugin, /agents

Converts inline sentence list into structured section 'Interactive slash
commands (inside the REPL)' with brief descriptions for each command.

Closes #155 gap: discovered during dogfood probing of help/USAGE parity.

No code changes. Pure documentation update.

YeonGyu-Kim 2dde749e41 test(#168c Task 4): add v1.5 emission baseline shape parity guard
Phase 0 Task 4 of the JSON Productization Program: CI shape parity guard.

This test locks the v1.5 emission baseline (documented in SCHEMAS.md § v1.5
Emission Baseline) so any future PR that introduces shape drift in a documented
verb fails this test at PR time.

Complements Task 2 (no-silent guarantee) by asserting SPECIFIC top-level key
sets, not just 'stdout is non-empty valid JSON'. If a verb adds/removes a
top-level field, this test fails with a clear error message pointing to
SCHEMAS.md § v1.5 Emission Baseline for update guidance.

Coverage:
- 8 success-path verbs with locked shape (help, version, doctor, skills,
  agents, system-prompt, bootstrap-plan, list-sessions)
- 2 error-path cases with locked error envelope shape (prompt-no-arg, doctor --foo)

Key enforcement rules:
- Success envelope: exact key set match per verb
- Error envelope: {error, hint, kind, type} (4 keys, all verbs)
- list-sessions deliberately kept as {command, sessions} (Phase 1 target)

Test design intent:
- Locks CURRENT (possibly imperfect) shape, NOT target shape
- Forces PR authors to update both code + SCHEMAS.md + test together
- Makes Phase 1 shape normalization PRs visible: 'update this test'

Phase 0 now COMPLETE:
- Task 1  Stream routing fix (cycle #89)
- Task 2  No-silent guarantee (cycle #90)
- Task 3  Per-verb emission inventory SCHEMAS.md (cycle #91)
- Task 4  CI shape parity guard (this cycle)

Tests: 18 output_format_contract tests all pass (+1 from Task 4).
v1.5 emission baseline now locked by code + tests + docs.

YeonGyu-Kim d270973a4a docs(#168c Task 3): add v1.5 Emission Baseline per-verb shape catalog to SCHEMAS.md
Phase 0 Task 3 of the JSON Productization Program: per-verb emission inventory.

Documents the actual binary behavior as of v1.5 (post-#168c fix, pre-Phase 1
shape normalization). Reference artifact for consumers building against v1.5,
not a target schema.

Catalog contents:
- 12 verbs using 'kind' field (help, version, doctor, mcp, skills, agents,
  sandbox, status, system-prompt, bootstrap-plan, export, acp)
- 1 verb using 'command' field (list-sessions) — Phase 1 normalization target
- 3 error-only verbs in test env (bootstrap, dump-manifests, state)
- Standard error envelope: {error, hint, kind, type} flat shape
- 9 machine-readable error kinds from classify_error_kind

Emission contract locked by:
- Task 1 (#168c routing fix, cycle #89)
- Task 2 (no-silent guarantee test, cycle #90)
- This catalog (human-readable reference, cycle #91)

Consumer guidance + Phase 1 normalization targets documented.

Phase 0 progress:
- Task 1 Stream routing fix
- Task 2 No-silent guarantee test
- Task 3 Per-verb emission inventory
- Task 4 pending: CI parity test

YeonGyu-Kim ca513dedb4 test(#168c Task 2): add no-silent emission contract guard for 14 verbs
Phase 0 Task 2 of the JSON Productization Program: no-silent guarantee.

The emission contract under --output-format json requires:
1. Success (exit 0) must produce non-empty stdout with valid JSON
2. Failure (exit != 0) must still emit JSON envelope on stdout (#168c)
3. Silent success (exit 0 + empty stdout) is forbidden

This test iterates 12 safe-success verbs + 2 error cases, asserting each
produces valid JSON on stdout. Any verb that regresses to silent emission
or wrong-stream routing will fail this test.

Covered verbs:
- Success: help, version, list-sessions, doctor, mcp, skills, agents,
  sandbox, status, system-prompt, bootstrap-plan, acp
- Error: prompt (no arg), doctor --foo

Phase 0 progress:
- Task 1  Stream routing (#168c fix)
- Task 2  No-silent guarantee (this test)
- Task 3  Per-verb emission inventory (SCHEMAS.md)
- Task 4  CI parity test (regression prevention)

Tests: 17 output_format_contract tests all pass (+1 from Task 2).

YeonGyu-Kim 0afdfb3481 fix(#168c): emit error envelopes to stdout under --output-format json
Under --output-format json, error envelopes were emitted to stderr via
eprintln!. This violated the emission contract: stdout should carry the
contractual envelope (success OR error); stderr is reserved for
non-contractual diagnostics.

Cycle #87 controlled matrix audit found bootstrap/dump-manifests/state
exhibited this pattern (exit 1, stdout 0 bytes, stderr N bytes under
--output-format json).

Fix: change eprintln! to println! for the JSON error envelope path in main().
Text mode continues to route errors to stderr (conventional).

Verification:
- bootstrap --output-format json: stdout now carries envelope, exit 1
- dump-manifests --output-format json: stdout now carries envelope, exit 1
- Text mode: errors still on stderr with [error-kind: ...] prefix (no regression)

Tests:
- Updated assert_json_error_envelope helper to read from stdout (was stderr)
- Added error_envelope_emitted_to_stdout_under_output_format_json_168c
  regression test that asserts envelope on stdout + non-JSON on stderr
- All 16 output_format_contract tests pass

Phase 0 Task 1 complete: emission routing fixed across all error-path verbs.
Phase 0 Task 2 (no-silent CI guarantee) remains.

YeonGyu-Kim 9325c6b2e7 locus(#164): add Phase 0 + v1.5 baseline; revised from 2-phase to 4-phase migration (cycle #85)
Fresh-dogfood validation (cycle #84, #168) proved the original locus premise was
underspecified. v1.0 was never a coherent contract — each verb has a bespoke JSON
shape with no coordination, and bootstrap JSON is completely broken (silent
failure, exit 0 no output).

Revised migration plan:
- Phase 0 (NEW): Emergency fix for silent failures (#168 bootstrap JSON)
- Phase 1 (NEW): v1.5 baseline — minimal JSON invariants across all 14 verbs
  - Every command emits valid JSON with --output-format json
  - Every command has top-level 'kind' field for verb ID
  - Every error envelope follows {error, hint, kind, type}
- Phase 2 (renamed from Phase 1): v2.0 wrapped envelope (opt-in)
- Phase 3 (renamed from Phase 2): v2.0 default
- Phase 4 (renamed from Phase 3): v1.0/v1.5 deprecation

Rationale:
- Can't migrate from 'incoherent' to 'coherent v2.0' in one jump
- Consumers need stable target (v1.5) to transition from
- Silent failures must be fixed BEFORE migration (consumers can't detect breakage)

Effort revision: ~9 dev-days (Phase 0: 1 + Phase 1: 3 + Phase 2: 5) vs original
~6 dev-days for direct v1.0→v2.0 (which would have failed).

Doctrine implication: Fresh-dogfood principle (#9, cycle #73) prevented a multi-day
migration from hitting an unsolvable baseline problem. Evidence-backed mid-design
correction.

YeonGyu-Kim 375043f691 docs: SCHEMAS.md — critical P0 fix: mark as target v2.0, not current v1.0 (#166 filed+closed)
SCHEMAS.md was presenting the target v2.0 schema as the current binary contract.
This is the source of truth document, so the misdocumentation propagated to every
downstream doc (USAGE.md, ERROR_HANDLING.md, CLAUDE.md all inherited the false
premise that v1.0 includes timestamp/command/exit_code/etc).

Fixed with:
1. CRITICAL header at top: marks entire doc as v2.0 target, not v1.0 reality
2. 'TARGET v2.0 SCHEMA' headers on Common Fields section
3. Comprehensive Appendix: v1.0 actual shape + migration timeline + v1.0 code example
4. Links to FIX_LOCUS_164.md + ERROR_HANDLING.md for v1.0 reality
5. FAQ: clarifies the version mismatch and when v2.0 ships

This closes the fourth P0 doc-truthfulness instance (4/4 in family):
- #78 USAGE.md: active misdocumentation (fixed #78)
- #79 ERROR_HANDLING.md: copy-paste trap (fixed #79)
- #165 CLAUDE.md: boundary collapse (fixed #81)
- #166 SCHEMAS.md: aspirational source doc (fixed #82)

Pattern is now crystallized: SCHEMAS.md was the aspirational source;
three downstream docs (USAGE, ERROR_HANDLING, CLAUDE) inherited the false v2.0-as-v1.0
claim. Fix the source (SCHEMAS.md), which eliminates the root cause for all four.

YeonGyu-Kim 4728b71795 docs: CLAUDE.md — fix target/current boundary collapse (#165 Option A)
CLAUDE.md was documenting the v2.0 target schema as if it were current binary
behavior. This misled validator/harness implementers into assuming the Rust
binary emits timestamp, command, exit_code, output_format, schema_version fields
when it doesn't.

Fixed by explicitly marking the boundary:
1. SCHEMAS.md section: now clearly labels 'target v2.0 design' and lists both
   v1.0 (actual binary) and v2.0 (target) field shapes
2. Clawable commands requirements: now explicitly separates v1.0 (current) and
   v2.0 (post-FIX_LOCUS_164) envelope requirements
3. Added inline migration note pointing to FIX_LOCUS_164.md

This closes #165 as the third P0 doc-truthfulness fix (Option A: preserve current
truth, add v2.0 target as separate labeled section).

P0 doc-truthfulness family pattern (all three related to #164 envelope divergence):
- #78 USAGE.md: active misdocumentation (fixed cycle #78)
- #79 ERROR_HANDLING.md: copy-paste trap (fixed cycle #79)
- #165 CLAUDE.md: target/current boundary collapse (fixed cycle #81)

YeonGyu-Kim 03a99b91b6 docs: ERROR_HANDLING.md — fix code examples to match v1.0 envelope (flat shape)
The Python code examples were accessing nested error.kind like envelope['error']['kind'],
but v1.0 emits flat envelopes with error as a STRING and kind at top-level.

Updated:
- Table header: now shows actual v1.0 shape {error: "...", kind: "...", type: "error"}
- match statement: switched from envelope.get('error',{}).get('kind') to envelope.get('kind')
- All ClawError raises: changed from envelope['error']['message'] to envelope.get('error','')
  because error field is a STRING in v1.0, not a nested object
- Added inline comments on every error case noting v1.0 vs v2.0 difference
- Appendix: split into v1.0 (actual/current) and v2.0 (target after FIX_LOCUS_164)

The code examples now work correctly against the actual binary.
This was active misdocumentation (P0 severity) — the Python examples would crash
if a consumer tried to use them.

YeonGyu-Kim 822228dd77 docs: USAGE.md — clarify JSON v1.0 envelope shape + migration notice for #164
The JSON output section was misleading — it claimed the binary emits
exit_code, command, timestamp, output_format, schema_version, and nested
error objects. The binary actually emits v1.0 flat shape (kind at top-level,
error as string, no common metadata fields).

Updated section:
- Documents actual v1.0 success and error envelope shapes
- Lists known issues (missing fields, overloaded kind, flat error)
- Shows how to dispatch on v1.0 (check type=='error' before reading kind)
- Warns users NOT to rely on kind alone
- Links to FIX_LOCUS_164.md for migration plan
- Explains Phase 1/2/3 timeline for v2.0 adoption

This is a doc-only fix that makes USAGE.md truthful about the current behavior
while preparing users for the coming schema migration.

YeonGyu-Kim 53aa929ad5 docs: add FIX_LOCUS_164.md — JSON envelope contract migration strategy
Cycle #77 deliverable. Escalates #164 from pinpoint to fix-locus cycle.

Documents:
- 100% divergence across all 14 JSON-emitting verbs (not a partial drift)
- Two envelope shapes: current flat vs. documented nested
- Phased migration: dual-mode → default bump → deprecation (3 phases)
- Shared wrapper helper pattern (json_envelope.rs)
- Per-verb migration template (before/after code)
- Error classification remapping table (cli_parse → parse, etc.)
- 6 acceptance criteria + 3 risk categories
- Rollout timeline: Phase 1 ~6 dev-days, v3.0 cutoff at ~8 months

Ready for author review + pilot implementation decision (which 3 verbs lead).

YeonGyu-Kim 9677eb7ada fix(#161): resolve actual HEAD path in git worktrees for correct Git SHA in build metadata
Problem: In git worktrees, .git is a pointer file (not a directory), so cargo's
rerun-if-changed=.git/HEAD never triggers when commits are made. This causes
claw version to report a stale SHA after new commits.

Solution: Add resolve_git_head_path() helper that detects worktree mode:
- If .git is a file: parse gitdir pointer, watch <gitdir>/HEAD
- If .git is a directory: watch .git/HEAD (regular repo)

This ensures build.rs invalidates on each commit, making version output truthful.

Verification: Binary built in worktree now reports correct SHA after commits
(before: stale, after: current HEAD).

Relates to ROADMAP #161 (filed cycle #65, implemented cycle #69).
Diagnostic-strictness family member.
Diff: 21 lines added (resolve_git_head_path + conditional rerun-if-changed).

YeonGyu-Kim 019be080df fix(#130e-B): route plugins/prompt --help to dedicated help topics
## What Was Broken (ROADMAP #130e Category B)

Two remaining surface-level help outliers after #130e-A:

    $ claw plugins --help
    Unknown /plugins action '--help'. Use list, install, enable, disable, uninstall, or update.

    $ claw prompt --help
    claw v0.1.0  (top-level help — wrong help topic)

`plugins` treated `--help` as an invalid subaction name. `prompt`
was explicitly listed in the early `wants_help` interception with
commit/pr/issue, which routed to top-level help instead of
prompt-specific help.

## Root Cause (Traced)

1. **plugins**: `parse_local_help_action()` didn't have a "plugins"
   arm, so `["plugins", "--help"]` returned None and continued into
   the `"plugins"` parser arm (main.rs:1031), which treated `--help`
   as the `action` argument. Runtime layer then rejected it as
   "Unknown action".

2. **prompt**: At main.rs:~800, there was an early interception for
   `--help` following certain subcommands (prompt, commit, pr, issue)
   that forced `wants_help = true`, routing to generic top-level help
   instead of letting parse_local_help_action produce a prompt-specific
   topic.

## What This Fix Does

Same pattern as #130c/#130d/#130e-A:

1. **LocalHelpTopic enum extended** with Plugins, Prompt variants
2. **parse_local_help_action() extended** to map both new cases
3. **Help topic renderers added** with accurate usage info
4. **Early prompt-interception removed** — prompt now falls through to
   parse_local_help_action like other subcommands. commit/pr/issue
   (which aren't actual subcommands yet) remain in the early list.

## Dogfood Verification

Before fix:
    $ claw plugins --help
    Unknown /plugins action '--help'. Use list, install, enable, ...

    $ claw prompt --help
    claw v0.1.0
    (top-level help, not prompt-specific)

After fix:
    $ claw plugins --help
    Plugins
      Usage            claw plugins [list|install|enable|disable|uninstall|update] [<target>]
      Purpose          manage bundled and user plugins from the CLI surface
      ...

    $ claw prompt --help
    Prompt
      Usage            claw prompt <prompt-text>
      Purpose          run a single-turn, non-interactive prompt and exit
      Flags            --model · --allowedTools · --output-format · --compact
      ...

## Non-Regression Verification

- `claw plugins` (no args) → still displays plugin inventory 
- `claw plugins list` → still works correctly 
- `claw prompt "text"` → still requires credentials, runs prompt 
- All 180 binary tests pass 
- All 466 library tests pass 

## Regression Tests Added (4+ assertions)

- `plugins --help` → HelpTopic(Plugins)
- `prompt --help` → HelpTopic(Prompt)
- Short forms `plugins -h` / `prompt -h` both work
- `prompt "hello world"` still routes to Prompt action with correct text

## HELP-PARITY SWEEP COMPLETE

All 22 top-level subcommands now emit proper help topics:

| Command | Status |
|---|---|
| help --help |  #130e-A |
| version --help |  pre-existing |
| status --help |  pre-existing |
| sandbox --help |  pre-existing |
| doctor --help |  pre-existing |
| acp --help |  pre-existing |
| init --help |  pre-existing |
| state --help |  pre-existing |
| export --help |  pre-existing |
| diff --help |  #130c |
| config --help |  #130d |
| mcp --help |  pre-existing |
| agents --help |  pre-existing |
| plugins --help |  #130e-B (this commit) |
| skills --help |  pre-existing |
| submit --help |  #130e-A |
| prompt --help |  #130e-B (this commit) |
| resume --help |  #130e-A |
| system-prompt --help |  pre-existing |
| dump-manifests --help |  pre-existing |
| bootstrap-plan --help |  pre-existing |

Zero outliers. Contract universally enforced.

YeonGyu-Kim 4f672f78d2 fix(#130e-A): route help/submit/resume --help to help topics before credential check
## What Was Broken (ROADMAP #130e, filed cycle #53)

Three subcommands leaked `missing_credentials` errors when called
with `--help`:

    $ claw help --help
    [error-kind: missing_credentials]
    error: missing Anthropic credentials...

    $ claw submit --help
    [error-kind: missing_credentials]
    error: missing Anthropic credentials...

    $ claw resume --help
    [error-kind: missing_credentials]
    error: missing Anthropic credentials...

This is the same dispatch-order bug class as #251 (session verbs).
The parser fell through to the credential check before help-flag
resolution ran. Critical discoverability gap: users couldn't learn
what these commands do without valid credentials.

## Root Cause (Traced)

`parse_local_help_action()` (main.rs:1260) is called early in
`parse_args()` (main.rs:1002), BEFORE credential check. But the
match statement inside only recognized:
status, sandbox, doctor, acp, init, state, export, version,
system-prompt, dump-manifests, bootstrap-plan, diff, config.

`help`, `submit`, `resume` were NOT in the list, so the function
returned `None`, and parsing continued to credential check which
then failed.

## What This Fix Does

Same pattern as #130c (diff) and #130d (config):

1. **LocalHelpTopic enum extended** with Meta, Submit, Resume variants
2. **parse_local_help_action() extended** to map the three new cases
3. **Help topic renderers added** with accurate usage info

Three-line change to parse_local_help_action:

    "help" => LocalHelpTopic::Meta,
    "submit" => LocalHelpTopic::Submit,
    "resume" => LocalHelpTopic::Resume,

Dispatch order (parse_args):
    1. --resume parsing
    2. parse_local_help_action() ← NOW catches help/submit/resume --help
    3. parse_single_word_command_alias()
    4. parse_subcommand() ← Credential check happens here

## Dogfood Verification

Before fix (all three):
    $ claw help --help
    [error-kind: missing_credentials]
    error: missing Anthropic credentials...

After fix:
    $ claw help --help
    Help
      Usage            claw help [--output-format <format>]
      Purpose          show the full CLI help text (all subcommands, flags, environment)
      ...

    $ claw submit --help
    Submit
      Usage            claw submit [--session <id|latest>] <prompt-text>
      Purpose          send a prompt to an existing managed session
      Requires         valid Anthropic credentials (when actually submitting)
      ...

    $ claw resume --help
    Resume
      Usage            claw resume [<session-id|latest>]
      Purpose          restart an interactive REPL attached to a managed session
      ...

## Non-Regression Verification

- `claw help` (no --help) → still shows full CLI help 
- `claw submit "text"` (with prompt) → still requires credentials 
- `claw resume` (bare) → still emits slash command guidance 
- All 180 binary tests pass 
- All 466 library tests pass 

## Regression Tests Added (6 assertions)

- `help --help` → routes to HelpTopic(Meta)
- `submit --help` → routes to HelpTopic(Submit)
- `resume --help` → routes to HelpTopic(Resume)
- Short forms: `help -h`, `submit -h`, `resume -h` all work

## Pattern Note

This is Category A of #130e (dispatch-order bugs). Same class as #251.
Category B (surface-parity: plugins, prompt) will be handled in a
follow-up commit/branch.

## Help-Parity Sweep Status

After cycle #52 (#130c diff, #130d config), help sweep revealed:

| Command | Before | After This Commit |

YeonGyu-Kim 7d74fac6d1 fix(#130d): accept --help / -h in claw config arm, route to help topic
## What Was Broken (ROADMAP #130d, filed cycle #52)

`claw config --help` was silently ignored — the command executed and
displayed the config dump instead of showing help:

    $ claw config --help
    Config
      Working directory /private/tmp/dogfood-probe-47
      Loaded files      0
      Merged keys       0
      (displays full config, not help)

Expected: help for the config command. Actual: silent acceptance of
`--help`, runs config display anyway.

This is the opposite outlier from #130c (which rejected help with an
error). Together they form the help-parity anomaly:
- #130c `diff --help` → error (rejects help)
- #130d `config --help` → silent ignore (runs command, ignores help)
- Others (status, mcp, export) → proper help
- Expected behavior: all commands should show help on `--help`

## Root Cause (Traced)

At main.rs:1050, the `"config"` parser arm parsed arguments positionally:

    "config" => {
        let tail = &rest[1..];
        let section = tail.first().cloned();
        // ... ignores unrecognized args like --help silently
        Ok(CliAction::Config { section, ... })
    }

Unlike the `diff` arm (#130c), `config` had no explicit check for
extra args. It positionally parsed the first arg as an optional
`section` and silently accepted/ignored any trailing arg, including
`--help`.

## What This Fix Does

Same pattern as #130c (help-surface parity):

1. **LocalHelpTopic enum extended** with new `Config` variant
2. **parse_local_help_action() extended** to map `"config"` → `LocalHelpTopic::Config`
3. **config arm guard added**: check for help flag before parsing section
4. **Help topic renderer added**: human-readable help text for config

Fix locus at main.rs:1050:

    "config" => {
        // #130d: accept --help / -h and route to help topic
        if rest.len() >= 2 && is_help_flag(&rest[1]) {
            return Ok(CliAction::HelpTopic(LocalHelpTopic::Config));
        }
        let tail = &rest[1..];
        // ... existing parsing continues
    }

## Dogfood Verification

Before fix:
    $ claw config --help
    Config
      Working directory ...
      Loaded files      0
      (no help, runs config)

After fix:
    $ claw config --help
    Config
      Usage            claw config [--cwd <path>] [--output-format <format>]
      Purpose          merge and display the resolved configuration
      Options          --cwd overrides the workspace directory
      Output           loaded files and merged key-value pairs
      Formats          text (default), json
      Related          claw status · claw doctor · claw init

Short form `claw config -h` also works.

## Non-Regression Verification

- `claw config` (no args) → still displays config dump 
- `claw config permissions` (section arg) → still works 
- All 180 binary tests pass 
- All 466 library tests pass 

## Regression Tests Added (4 assertions)

- `config --help` → routes to `HelpTopic(LocalHelpTopic::Config)`
- `config -h` (short form) → routes to help topic
- bare `config` (no args) → still routes to `Config` action
- `config permissions` (with section) → still works correctly

## Pattern Note

#130c and #130d form a pair: two outlier failure modes in help
handling for local introspection commands:
- #130c `diff` rejected help (loud error) → fixed with guard + routing
- #130d `config` silently ignored help (silent accept) → fixed with same pattern

Both are now consistent with the rest of the CLI (status, mcp, export, etc.).

YeonGyu-Kim b24bc1af56 fix(#130c): accept --help / -h in claw diff arm
## What Was Broken (ROADMAP #130c, filed cycle #50)

`claw diff --help` was rejected with:

    [error-kind: unknown]
    error: unexpected extra arguments after `claw diff`: --help

Other local introspection commands accept --help fine:
- `claw status --help` → shows help 
- `claw mcp --help` → shows help 
- `claw export --help` → shows help 
- `claw diff --help` → error  (outlier)

This is a help-surface parity bug: `diff` is the only local command
that rejects --help as "extra arguments" before the help detector
gets a chance to run.

## Root Cause (Traced)

At main.rs:1063, the `"diff"` parser arm rejected ALL extra args:

    "diff" => {
        if rest.len() > 1 {
            return Err(format!("unexpected extra arguments after `claw diff`: {}", ...));
        }
        Ok(CliAction::Diff { output_format })
    }

When parsing `["diff", "--help"]`, `rest.len() > 1` was true (length
is 2) and `--help` was rejected as extra argument.

Other commands (status, sandbox, doctor, init, state, export, etc.)
routed through `parse_local_help_action()` which detected
`--help` / `-h` and routed to a LocalHelpTopic. The `diff` arm
lacked this guard.

## What This Fix Does

Three minimal changes:

1. **LocalHelpTopic enum extended** with new `Diff` variant
2. **parse_local_help_action() extended** to map `"diff"` → `LocalHelpTopic::Diff`
3. **diff arm guard added**: check for help flag before extra-args validation
4. **Help topic renderer added**: human-readable help text for diff command

Fix locus at main.rs:1063:

    "diff" => {
        // #130c: accept --help / -h as first argument and route to help topic
        if rest.len() == 2 && is_help_flag(&rest[1]) {
            return Ok(CliAction::HelpTopic(LocalHelpTopic::Diff));
        }
        if rest.len() > 1 { /* existing error */ }
        Ok(CliAction::Diff { output_format })
    }

## Dogfood Verification

Before fix:
    $ claw diff --help
    [error-kind: unknown]
    error: unexpected extra arguments after `claw diff`: --help

After fix:
    $ claw diff --help
    Diff
      Usage            claw diff [--output-format <format>]
      Purpose          show local git staged + unstaged changes
      Requires         workspace must be inside a git repository
      ...

And `claw diff -h` (short form) also works.

## Non-Regression Verification

- `claw diff` (no args) → still routes to Diff action correctly
- `claw diff foo` (unknown arg) → still rejected as "unexpected extra arguments"
- `claw diff --output-format json` (valid flag) → still works
- All 180 binary tests pass
- All 466 library tests pass

## Regression Tests Added (4 assertions)

- `diff --help` → routes to HelpTopic(LocalHelpTopic::Diff)
- `diff -h` (short form) → routes to HelpTopic(LocalHelpTopic::Diff)
- bare `diff` → still routes to Diff action
- `diff foo` (unknown arg) → still errors with "extra arguments"

## Pattern

Follows #141 help-consistency work (extending LocalHelpTopic to
cover more subcommands). Clean surface-parity fix: identify the
outlier, add the missing guard. Low-risk, high-clarity.

YeonGyu-Kim 38858e7bd5 fix(#130b): enrich filesystem I/O errors with operation + path context
## What Was Broken (ROADMAP #130b, filed cycle #47)

In a fresh workspace, running:

    claw export latest --output /private/nonexistent/path/file.jsonl --output-format json

produced:

    {"error":"No such file or directory (os error 2)","hint":null,"kind":"unknown","type":"error"}

This violates the typed-error contract:
- Error message is a raw errno string with zero context
- Does not mention the operation that failed (export)
- Does not mention the target path
- Classifier defaults to "unknown" even though the code path knows
  this is a filesystem I/O error

## Root Cause (Traced)

run_export() at main.rs:~6915 does:

    fs::write(path, &markdown)?;

When this fails:
1. io::Error propagates via ? to main()
2. Converted to string via .to_string() in error handler
3. classify_error_kind() cannot match "os error" or "No such file"
4. Defaults to "kind": "unknown"

The information is there at the source (operation name, target path,
io::ErrorKind) but lost at the propagation boundary.

## What This Fix Does

Three changes:

1. **New helper: contextualize_io_error()** (main.rs:~260)
   Wraps an io::Error with operation name + target path into a
   recognizable message format:

       "{operation} failed: {target} ({error})"

2. **Classifier branch added** (classify_error_kind at main.rs:~270)
   Recognizes the new format and classifies as "filesystem_io_error":

       else if message.contains("export failed:") ||
               message.contains("diff failed:") ||
               message.contains("config failed:") {
           "filesystem_io_error"
       }

3. **run_export() wired** (main.rs:~6915)
   fs::write() call now uses .map_err() to enrich io::Error:

       fs::write(path, &markdown).map_err(|e| -> Box<dyn std::error::Error> {
           contextualize_io_error("export", &path.display().to_string(), e).into()
       })?;

## Dogfood Verification

Before fix:

    {"error":"No such file or directory (os error 2)","kind":"unknown","type":"error"}

After fix:

    {"error":"export failed: /private/nonexistent/path/file.jsonl (No such file or directory (os error 2))","kind":"filesystem_io_error","type":"error"}

The envelope now tells downstream claws:
- WHAT operation failed (export)
- WHERE it failed (the path)
- WHAT KIND of failure (filesystem_io_error)
- The original errno detail preserved for diagnosis

## Non-Regression Verification

- Successful export still works (emits "kind": "export" envelope as before)
- Session not found error still emits "session_not_found" (not filesystem)
- missing_credentials still works correctly
- cli_parse still works correctly
- All 180 binary tests pass
- All 466 library tests pass
- All 95 compat-harness tests pass

## Regression Tests Added

Inside the main CliAction test function:

- "export failed:" pattern classifies as "filesystem_io_error" (not "unknown")
- "diff failed:" pattern classifies as "filesystem_io_error"
- "config failed:" pattern classifies as "filesystem_io_error"
- contextualize_io_error() produces a message containing operation name
- contextualize_io_error() produces a message containing target path
- Messages produced by contextualize_io_error() are classifier-recognizable

## Scope

This is the minimum viable fix: enrich export's fs::write with context.
Future work (filed as part of #130b scope): apply same pattern to
other filesystem operations (diff, plugins, config fs reads, session
store writes, etc.). Each application is a copy-paste of the same
helper pattern.

## Pattern

Follows #145 (plugins parser interception), #248-249 (arm-level leak
templates). Helper + classifier + call site wiring. Minimal diff,
maximum observability gain.

YeonGyu-Kim ec5a6b95b8 fix(#251): intercept session-management verbs at top-level parser to bypass credential check
## What Was Broken (ROADMAP #251)

Session-management verbs (list-sessions, load-session, delete-session,
flush-transcript) were falling through to the parser's `_other => Prompt`
catchall at main.rs:~1017. This construed them as `CliAction::Prompt {
prompt: "list-sessions", ... }` which then required credentials via the
Anthropic API path. The result: purely-local session operations emitted
`missing_credentials` errors instead of session-layer envelopes.

## Acceptance Criterion

The fix's essential requirement (stated by gaebal-gajae):
**"These 4 verbs stop falling through to Prompt and emitting `missing_credentials`."**
Not "all 4 are fully implemented to spec" — stubs are acceptable for
delete-session and flush-transcript as long as they route LOCALLY.

## What This Fix Does

Follows the exact pattern from #145 (plugins) and #146 (config/diff):

1. **CliAction enum** (main.rs:~700): Added 4 new variants.
2. **Parser** (main.rs:~945): Added 4 match arms before the `_other => Prompt`
   catchall. Each arm validates the verb's positional args (e.g., load-session
   requires a session-id) and rejects extra arguments.
3. **Dispatcher** (main.rs:~455):
   - list-sessions → dispatches to `runtime::session_control::list_managed_sessions_for()`
   - load-session → dispatches to `runtime::session_control::load_managed_session_for()`
   - delete-session → emits `not_yet_implemented` error (local, not auth)
   - flush-transcript → emits `not_yet_implemented` error (local, not auth)

## Dogfood Verification

Run on clean environment (no credentials):

```bash
$ env -i PATH=$PATH HOME=$HOME claw list-sessions --output-format json
{
  "command": "list-sessions",
  "sessions": [
    {"id": "session-1775777421902-1", ...},
    ...
  ]
}
# ✓ Session-layer envelope, not auth error

$ env -i PATH=$PATH HOME=$HOME claw load-session nonexistent --output-format json
{"error":"session not found: nonexistent", "kind":"session_not_found", ...}
# ✓ Local session_not_found error, not missing_credentials

$ env -i PATH=$PATH HOME=$HOME claw delete-session test-id --output-format json
{"command":"delete-session","error":"not_yet_implemented","kind":"not_yet_implemented","type":"error"}
# ✓ Local not_yet_implemented, not auth error

$ env -i PATH=$PATH HOME=$HOME claw flush-transcript test-id --output-format json
{"command":"flush-transcript","error":"not_yet_implemented","kind":"not_yet_implemented","type":"error"}
# ✓ Local not_yet_implemented, not auth error
```

Regression sanity:

```bash
$ claw plugins --output-format json  # #145 still works
$ claw prompt "hello" --output-format json  # still requires credentials correctly
$ claw list-sessions extra arg --output-format json  # rejects extra args with cli_parse
```

## Regression Tests Added

Inside `removed_login_and_logout_subcommands_error_helpfully` test function:

- `list-sessions` → CliAction::ListSessions (both text and JSON output)
- `load-session <id>` → CliAction::LoadSession with session_reference
- `delete-session <id>` → CliAction::DeleteSession with session_id
- `flush-transcript <id>` → CliAction::FlushTranscript with session_id
- Missing required arg errors (load-session and delete-session without ID)
- Extra args rejection (list-sessions with extra positional args)

All 180 binary tests pass. 466 library tests pass.

## Fix Scope vs. Full Implementation

This fix addresses #251 (dispatch-order bug) and #250's Option A (implement
the surfaces). list-sessions and load-session are fully functional via
existing runtime::session_control helpers. delete-session and flush-transcript
are stubbed with local "not yet implemented" errors to satisfy #251's
acceptance criterion without requiring additional session-store mutations
that can ship independently in a follow-up.

## Template

Exact same pattern as #145 (plugins) and #146 (config/diff): top-level
verb interception → CliAction variant → dispatcher with local operation.

Closes #251. Addresses #250 Option A for 4 verbs. Does not block #250

YeonGyu-Kim e5f124ca1a docs(#162): add USAGE.md sections for dump-manifests, bootstrap-plan, acp, export
Parity audit (cycle #67) found 4 verbs were in claw --help but absent from USAGE.md:
- dump-manifests: upstream manifest export for parity work
- bootstrap-plan: startup component graph for debugging
- acp: Zed editor integration status (discoverability only, tracking ROADMAP #76)
- export: session transcript export (requires --resume)

Each section follows the existing USAGE.md pattern:
- Purpose statement
- Example usage
- When-to-use guidance
- Related error modes where applicable

Coverage: 12/12 binary verbs now documented (was 8/12).

YeonGyu-Kim 91389933a5 fix(#160): reserved-semantic verbs with positional args now emit slash-command guidance
Verbs with CLI-reserved positional-arg meanings (resume, compact, memory,
commit, pr, issue, bughunter) were falling through to Prompt dispatch
when invoked with args, causing users to see 'missing_credentials' errors
instead of guidance that the verb is a slash command.

#160 investigation revealed the underlying design question: which verbs
are 'promptable' (can start a prompt like 'explain this pattern') vs.
'reserved' (have specific CLI meaning like 'resume SESSION_ID')?

This fix implements the reserved-verb classification: at parse time,
intercept reserved verbs with trailing args and emit slash-command guidance
before falling through to Prompt. Promptable verbs (explain, bughunter, clear)
continue to route to Prompt as before.

Helper: is_reserved_semantic_verb() lists the reserved set.
All 181 tests pass (no regressions).

YeonGyu-Kim 9f9603251e fix(#122b): claw doctor warns when cwd is broad path (home/root)
## What Was Broken

`claw doctor` reported "Status: ok" when run from ~/ or /, but `claw
prompt` in the same directory would error out with:

    error: claw is running from a very broad directory (/Users/yeongyu).
    The agent can read and search everything under this path.

Diagnostic deception: doctor said green, prompt said red. User runs
doctor to check their setup, sees all green, runs prompt, gets blocked.
Trust in doctor erodes.

This is the exact pattern captured in the 'Diagnostic Commands Must Be
At Least As Strict As Runtime Commands' principle recorded in ROADMAP.md
at cycle #57.

## Root Cause

Two code paths perform the broad-cwd check:
- CliAction::Prompt handler → `enforce_broad_cwd_policy()` (errors out)
- CliAction::Repl handler → same function

But render_doctor_report() never called detect_broad_cwd(). The workspace
health check only looked at whether cwd was inside a git project, not
whether cwd was a dangerously broad path.

## What This Fix Does

Extend `check_workspace_health()` to also probe `detect_broad_cwd()`:

    let broad_cwd = detect_broad_cwd();
    let (level, summary) = match (in_repo, &broad_cwd) {
        (_, Some(path)) => (
            DiagnosticLevel::Warn,
            format!(
                "current directory is a broad path ({}); Prompt/REPL will \
                 refuse to run here without --allow-broad-cwd",
                path.display()
            ),
        ),
        (true, None) => (DiagnosticLevel::Ok, "project root detected"),
        (false, None) => (DiagnosticLevel::Warn, "not inside a git project"),
    };

The check now warns about BOTH failure modes with clear messaging about
what Prompt/REPL will do.

## Dogfood Verification

Before fix:
    $ cd ~ && claw doctor
    Workspace
      Status           warn
      Summary          current directory is not inside a git project
    [all green otherwise]

    $ echo | claw prompt "test"
    error: claw is running from a very broad directory (/Users/yeongyu)...

After fix:
    $ cd ~ && claw doctor
    Workspace
      Status           warn
      Summary          current directory is a broad path (/Users/yeongyu);
                       Prompt/REPL will refuse to run here without
                       --allow-broad-cwd

    $ cd / && claw doctor
    Workspace
      Status           warn
      Summary          current directory is a broad path (/); ...

Non-regression:
    $ cd /tmp/my-project && claw doctor
    Workspace
      Status           warn
      Summary          current directory is not inside a git project
    (unchanged)

    $ cd /path/to/real/git/project && claw doctor
    Workspace
      Status           ok
      Summary          project root detected on branch main
    (unchanged)

## Regression Tests Added

- `workspace_check_in_project_dir_reports_ok` — non-broad + in-project = OK
- `workspace_check_outside_project_reports_warn` — non-broad + not-in-project = Warn with 'not inside git project' summary

- Per-cluster merge prerequisites and validation steps
- Conflict risk assessment (Cluster 2 #122/#122b have same edit locus)
- Post-merge validation checklist (build + test + dogfood)
- Timeline estimate (~60 min for full 17-branch queue)

Addresses the final integration step: once branches are reviewed, knowing
the safe merge order matters. This artifact pre-answers that question.

Applied doctrine: integration-support artifacts (cycle #64) reduce reviewer
friction. At 17-branch saturation, a merge-safe checklist is first-class work.

YeonGyu-Kim 10201c7199 docs(#250, #251): Align SCHEMAS.md with actual binary, downgrade #250 to scope-reduced
Cycle #46 follow-up to cycle #45's #251 implementation. Closes #250's
implementation urgency by aligning docs with reality.

SCHEMAS.md Updates:
For each of the 4 session-management verbs, added:
1. Status marker (Implemented or Stub only)
2. Actual binary envelope (shape produced by the #251-fixed binary)
3. Aspirational (future) shape (original SCHEMAS.md content, preserved as target)
4. Gap notes where the two diverge

Per-verb status:
- list-sessions: Implemented, nested field layout
- load-session: Implemented, nested session object with local session_not_found error
- delete-session: Stub, emits not_yet_implemented (local error, not auth)
- flush-transcript: Stub, emits not_yet_implemented (local error, not auth)

ROADMAP.md Updates:
- #251 marked CLOSED: Full status with commit ref, test counts.
- #250 marked SCOPE-REDUCED: Option A resolved by #251, Option C moot,
  only Option B (doc alignment) remains as future cleanup.

Why this matters:
Every code change should close its documentation loop. #251 landed on
the branch, but SCHEMAS.md still described aspirational shapes without
marking which were implemented. Claws reading SCHEMAS.md would have
assumed full conformance and hit surprises. Now the document tells the
truth about which verbs work, which are stubs, and why.

YeonGyu-Kim 1988496081 ROADMAP #130: re-verify still-open on main HEAD 186d42f; add classifier-cluster pairing note
Cycle #39 dogfood re-verification of #130 (filed 2026-04-20). All 5
filesystem failure modes reproduce identically on main HEAD 186d42f,
2 days after original filing. Gap is unchanged.

## What's Added

1. **[STILL OPEN — re-verified 2026-04-22 cycle #39]** marker on the
   entry so readers can see immediately that the pinpoint hasn't been
   accidentally closed.

2. Full 5-mode repro output preserved verbatim for the current HEAD,
   so future re-verifications have a concrete baseline to diff against.

3. **New evidence not in original filing**: the classifier actively
   chose `kind: "unknown"` rather than just omitting the field. This
   means classify_error_kind() has NO substring match for "Is a
   directory", "No such file", "Operation not permitted", or "File
   exists". The typed-error contract is thus twice-broken on this path.

4. **Pairing with #247/#248/#249 classifier sweep**: the classifier-level
   part of #130 could land in the same sweep (add substring branches
   for io::ErrorKind strings). The context-preservation part (fix
   run_export's bare `?`) is a separate, larger change.

## Why Re-Verification Not Re-Filing

Per cycle #24 discipline: speculative re-filings add noise, real
confirmations add truth. #130 was already filed with exact repros, code
trace, and fix shape. My dogfood hit the same gap on fresh HEAD — the
right output is confirming the gap is still there (not filing #251 for
the same bug).

This is the same pattern as cycle #32's "mark #127 CLOSED" reality-sync:
documentation-drift prevention through explicit status markers.

## New Pattern

"Reality-sync via re-verification" — re-running a filed pinpoint's
repro on fresh HEAD and adding the timestamp + output proves the gap
is still real without inventing new filings. Cycle #24 calibration
keeps ROADMAP entries honest.

Per cycle #24 calibration:
- Red-state bug? ⚠️ borderline (errors surfaced, but kind=unknown is
  demonstrably wrong on a path where the system knows the errno)
- Real friction? ✓ (re-verified on fresh HEAD)
- Evidence-backed? ✓ (5-mode repro + classifier trace)
- Same-cycle fix? ✗ (classifier-level part could join #247/#248/#249
  sweep; context-preservation part is larger refactor)
- Implementation cost? Classifier part ~10 lines; full context fix ~60 lines

YeonGyu-Kim 7a7c960628 fix: #247 classify prompt-related parse errors + unify JSON hint plumbing
Cycle #34 dogfood follow-through on Jobdori cycle #33 pinpoint (#247 filed
at fbcbe9d). Closes the two typed-error contract drifts surfaced in that
pinpoint against the Rust `claw` binary.

## What was wrong

1. `classify_error_kind()` (main.rs:~251) used substring matching but did
   NOT match two common prompt-related parse errors:
     - "prompt subcommand requires a prompt string"
     - "empty prompt: provide a subcommand..."
   Both fell through to `"unknown"`. §4.44 typed-error contract specifies
   `parse | usage | unknown` as distinct classes, so claws dispatching on
   `error.kind == "cli_parse"` missed those paths entirely.

2. JSON mode dropped the `Run `claw --help` for usage.` hint. Text mode
   appends it at stderr-print time (main.rs:~234) AFTER split_error_hint()
   has already serialized the envelope, so JSON consumers never saw it.
   Text-mode humans got an actionable pointer; machine consumers did not.

## Fix

Two small, targeted edits:

1. `classify_error_kind()`: add explicit branches for "prompt subcommand
   requires" and "empty prompt:" (the latter anchored with `starts_with`
   so it never hijacks unrelated error messages containing the word).
   Both route to `cli_parse`.

2. JSON error render path in `main()`: after calling split_error_hint(),
   if the message carried no embedded hint AND kind is `cli_parse` AND
   the short-reason does not already embed a `claw --help` pointer,
   synthesize the same `Run `claw --help` for usage.` trailer that
   text-mode stderr appends. The embedded-pointer check prevents
   duplication on the `empty prompt: ... (run `claw --help`)` message
   which already carries inline guidance.

## Verification

Direct repro on the compiled binary:

    $ claw --output-format json prompt
    {"error":"prompt subcommand requires a prompt string",
     "hint":"Run `claw --help` for usage.",
     "kind":"cli_parse","type":"error"}

    $ claw --output-format json ""
    {"error":"empty prompt: provide a subcommand (run `claw --help`) or a non-empty prompt string",
     "hint":null,"kind":"cli_parse","type":"error"}

    $ claw --output-format json doctor --foo   # regression guard
    {"error":"unrecognized argument `--foo` for subcommand `doctor`",
     "hint":"Run `claw --help` for usage.",
     "kind":"cli_parse","type":"error"}

Text mode unchanged in shape; `[error-kind: ...]` prefix now reads
`cli_parse` for the two previously-misclassified paths.

## Regression coverage

- Unit test `classify_error_kind_covers_prompt_parse_errors_247`: locks
  both patterns route to `cli_parse` AND that generic "prompt"-containing
  messages still fall through to `unknown`.
- Integration tests in `tests/output_format_contract.rs`:
  * prompt_subcommand_without_arg_emits_cli_parse_envelope_with_hint_247
  * empty_positional_arg_emits_cli_parse_envelope_247
  * whitespace_only_positional_arg_emits_cli_parse_envelope_247
  * unrecognized_argument_still_classifies_as_cli_parse_247_regression_guard
- Full rusty-claude-cli test suite: 218 tests pass (180 bin unit + 15
  output_format_contract + 12 resume_slash + 7 compact + 3 mock + 1 cli).

## Family / related

Joins §4.44 typed-envelope contract gap family closure: #130, #179, #181,
and now **#247**. All four quartet items now have real fixes landed on
the canonical binary surface rather than only the Python harness.

ROADMAP.md: #247 marked CLOSED with before/after evidence preserved.
2026-04-30 11:03:06 +09:00
YeonGyu-Kim 917738820f docs: cycle #32 — mark #127 CLOSED; document in-flight branch obsolescence
Cycle #32 dogfood finding: #127 was fixed on main via `a3270db` + `79352a2`
(2026-04-20), but the ROADMAP.md entry still lacked a [CLOSED] marker.
The in-flight branches `feat/jobdori-127-clean` and
`feat/jobdori-127-verb-suffix-flags` were superseded and are now obsolete.

## What This Fixes

**Documentation drift:** Pinpoint #127 was complete in code but unmarked
in ROADMAP. New contributors checking the roadmap would see it as open
work, potentially duplicating effort.

**Stale branches:** Two branches (`feat/jobdori-127-clean`,
`feat/jobdori-127-verb-suffix-flags`) contain the fix attempt bundled
with an unrelated large-scope refactor (5365 lines removed from
ROADMAP.md, root-level governance docs deleted, command infra refactored).
Their fix was superseded; branches are functionally obsolete.

## Verification

Re-verified all 4 #127 scenarios pass on main HEAD `b903e16`:

  $ claw doctor --json        → rejected with "did you mean" hint
  $ claw doctor garbage       → rejected
  $ claw doctor --unknown-flag → rejected
  $ claw doctor --output-format json → works (canonical form)

All behavior matches #127 acceptance criteria.

## Cluster Impact

Post-closure: **parser-level trust gap quintet (#108 + #117 + #119 + #122
+ #127) is 5/5 closed**. The `_other => Prompt` fall-through audit is
complete.

## Discipline Check

Per cycle #24 calibration:
- Red-state bug? ✗ (behavior is correct on main)
- Real friction? ✓ (ROADMAP drift; obsolete branches adrift)
- Evidence-backed? ✓ (dogfood probe confirmed closure; git log confirmed
  supersession; branch diff confirmed scope contamination)

## Relationship to Gaebal-gajae's Option A Guidance

Cycle #32 started by proposing separating the #127 fix from the attached
refactor. On deeper probe, discovered the fix was already superseded on
main via different commits. Option A (separate the fix) is retroactively
satisfied: the fix landed cleanly, the refactor never did.

The remaining action is governance hygiene: mark closure, document
supersession, flag obsolete branches for deletion.

## Next Actions (not in this commit)

- Delete `feat/jobdori-127-clean` locally and on fork (after confirmation)
- Delete `feat/jobdori-127-verb-suffix-flags` locally and on fork
- Monitor whether any attached refactor content should be re-proposed in
  its own scoped PR

YeonGyu-Kim 298b24ecf9 test: cycle #30 — lock OPT_OUT surface rejection (close parity test gap)
Cycle #30 dogfood found a testing gap: OPT_OUT surfaces were classified
in code but their REJECTION behavior was never regression-tested.

## The Gap

OPT_OUT_AUDIT.md declares 12 surfaces as intentionally exempt from
--output-format. The test suite had:

-  test_clawable_surface_has_output_format (CLAWABLE must accept)
-  test_every_registered_command_is_classified (no orphans)
-  Nothing verifying OPT_OUT surfaces REJECT --output-format

If a developer accidentally added --output-format to 'summary' (one of
the 12 OPT_OUT surfaces), no test would catch the silent promotion.

The classification was governed, but the rejection behavior was NOT.

## What Changed

Added TestOptOutSurfaceRejection to test_cli_parity_audit.py with 14 tests:

1. **12 parametrized tests** — one per OPT_OUT surface, verifying each
   rejects --output-format with an argparse error.
2. **test_opt_out_set_matches_audit_document** — verifies OPT_OUT_SURFACES
   constant matches the declared 12 surfaces in OPT_OUT_AUDIT.md.
3. **test_opt_out_count_matches_declared** — sanity check that the count
   stays at 12 as documented.

## Symmetry Achieved

Before: only CLAWABLE acceptance tested
  CLAWABLE accepts --output-format 
  OPT_OUT behavior: untested

After: full parity coverage
  CLAWABLE accepts --output-format 
  OPT_OUT rejects --output-format 
  Audit doc ↔ constant kept in sync 

This completes the parity enforcement loop: every new surface is
explicitly IN or OUT, and BOTH directions are regression-locked.

## Promotion Path Preserved

When a real OPT_OUT surface gains genuine demand (per OPT_OUT_DEMAND_LOG.md):
1. Move from OPT_OUT_SURFACES to CLAWABLE_SURFACES
2. Update OPT_OUT_AUDIT.md with promotion rationale
3. Remove from this test's expected rejections
4. Tests pass (rejection test no longer runs; acceptance test now required)

Graceful promotion; no accidental drift.

## Test Count

- 222 → 236 passing (+14, zero regressions)
- 12 parametrized + 2 metadata = 14 new tests

## Discipline Check

Per cycle #24 calibration:
- Red-state bug? ✗ (no broken behavior)
- Real friction? ✓ (testing gap discovered by dogfood)
- Evidence-backed? ✓ (systematic probe revealed missing coverage)

This is the cycle #27 taxonomy (structural / quality / cross-channel /
text-vs-JSON divergence) extending into classification: not just 'is the
envelope right?' but 'is the OPPOSITE-OF-envelope right?'

Future cycles can apply the same principle to other classifications:
every governed non-goal deserves regression tests that lock its
non-goal-ness.

Classification:
- Real friction: ✓ (cycle #30 dogfood)
- Evidence-backed: ✓ (gap discovered by systematic surface audit)
- Same-cycle fix: ✓ (maintainership discipline)

with --output-format json and noticed OPT_OUT rejection pattern was
unverified by any dedicated test.

YeonGyu-Kim 71830d7d48 docs+test: cycle #29 — document + lock text-mode vs JSON-mode exit divergence
Cycle #29 dogfood found a real pinpoint: cross-mode exit code divergence.

## The Pinpoint

Dogfooding the CLI revealed that unknown subcommand errors return different
exit codes depending on output mode:

  $ python3 -m src.main nonexistent-cmd                        # exit 2
  $ python3 -m src.main nonexistent-cmd --output-format json   # exit 1

ERROR_HANDLING.md documented the exit-code contract (1=parse, 2=timeout)
but did NOT explicitly state the contract applies only to JSON mode. Text
mode follows argparse defaults (exit 2 for any parse error), which
violates the documented contract when interpreted generally.

A claw using text mode with 'claw nonexistent' would see exit 2 and
misclassify as timeout per the docs. Real protocol contract gap, not
implementation bug.

## Classification

This is a DOCUMENTATION gap, not a behavior bug:
- Text mode follows argparse convention (reasonable for humans)
- JSON mode normalizes to documented contract (reasonable for claws)
- The divergence is intentional; only the docs were silent about it

Fix = document the divergence explicitly + lock it with tests.

NOT fix = change text mode exit code to 1 (would break argparse
conventions and confuse human users).

## Documentation Changes

ERROR_HANDLING.md:
1. Added IMPORTANT callout in Quick Reference section:
   'The exit code contract applies ONLY when --output-format json is
    explicitly set. Text mode follows argparse conventions.'
2. New 'Text mode vs JSON mode exit codes' table showing exact divergence:
   - Unknown subcommand: text=2, json=1
   - Missing required arg: text=2, json=1
   - Session not found: text=1, json=1 (app-level, identical)
   - Success: text=0, json=0 (identical)
   - Timeout: text=2, json=2 (identical, #161)
3. Practical rule: 'always pass --output-format json'

## Tests Added (5)

TestTextVsJsonModeDivergence in test_cross_channel_consistency.py:

1. test_unknown_command_text_mode_exits_2 — text mode argparse default
2. test_unknown_command_json_mode_exits_1 — JSON mode contract normalized
3. test_missing_required_arg_text_mode_exits_2 — same for missing args
4. test_missing_required_arg_json_mode_exits_1 — same normalization
5. test_success_path_identical_in_both_modes — success exit identical

These tests LOCK the expected divergence so:
- Documentation stays aligned with implementation
- Future changes (either direction) are caught as intentional
- Claws trust the docs

## Test Status

- 217 → 222 tests passing (+5)
- Zero regressions

## Discipline

This cycle follows the cycle #28 template exactly:
- Dogfood probe revealed real friction (test said exit=2, docs said exit=1)
- Minimal fix shape (documentation clarification, not code change)
- Regression guard via tests
- Evidence-backed, not speculative

Relationship to #181:
- #181 fixed env.exit_code != process exit (WITHIN JSON mode)
- #29 clarifies exit code contract scope (ONLY JSON mode)
- Both establish: exit codes are deterministic, but only when --output-format json

---

Classification (per cycle #24 calibration):
- Red-state bug? ✗ (behavior was reasonable, docs were incomplete)
- Real friction? ✓ (docs/code divergence revealed by dogfood)
- Evidence-backed? ✓ (test suite probed both modes, found the gap)

Source: Jobdori cycle #29 proactive dogfood — in response to Clawhip nudge
for pinpoint hunting. Found that text-mode errors return exit 2 but
ERROR_HANDLING.md implied exit 1 was the parse-error contract universally.

YeonGyu-Kim ef432f164e feat: #180 implement --version flag for metadata protocol (#28 proactive demand)
Cycle #28 closes the low-hanging metadata protocol gap identified in #180.

## The Gap

Pinpoint #180 (filed cycle #24) documented a metadata protocol gap:
- `--help` works (argparse default)
- `--version` does NOT exist

The ROADMAP entry deferred implementation pending demand. Cycle #28 dogfood
probe found this during routine invariant audit (attempt to call `--version`
as part of comprehensive CLI surface coverage). This is concrete evidence of
real friction, not speculative gap-filling.

## Implementation

Added `--version` flag to argparse in `build_parser()`:

```python
parser.add_argument('--version', action='version', version='claw-code 1.0.0 (Python harness)')
```

Simple one-liner. Follows Python argparse conventions (built-in action='version').

## Tests Added (3)

TestMetadataFlags in test_exec_route_bootstrap_output_format.py:

1. test_version_flag_returns_version_text — `claw --version` prints version
2. test_help_flag_returns_help_text — `claw --help` still works
3. test_help_still_works_after_version_added — Both -h and --help work

Regression guard on the original help surface.

## Test Status

- 214 → 217 tests passing (+3)
- Zero regressions
- Full suite green

## Discipline

This cycle exemplifies the cycle #24 calibration:
- #180 was filed as 'deferred pending demand'
- Cycle #28 dogfood found actual friction (proactive test coverage gap)
- Evidence = concrete ('--version not found during invariant audit')
- Action = minimal implementation + regression tests
- No speculation, no feature creep, no implementation before evidence

Not 'we imagined someone might want this.' Instead: 'we tried to call it
during routine maintenance, got ENOENT, fixed it.'

YeonGyu-Kim f012cadd64 test: cycle #27 — cross-channel consistency audit suite
Cycle #27 ships a new test class systematizing the three-layer protocol
invariant framework.

## Context

After cycles #20–#26, the protocol has three distinct invariant classes:

1. **Structural compliance** (#178): Does the envelope exist?
2. **Quality compliance** (#179): Is stderr silent + error message truthful?
3. **Cross-channel consistency** (#181 + NEW): Do multiple channels agree?

#181 revealed a critical gap: the second test class was incomplete.
Envelopes could be structurally valid, quality-compliant, but still
lie about their own state (envelope.exit_code != actual exit).

## New Test Class

TestCrossChannelConsistency in test_cross_channel_consistency.py captures
the third invariant layer with 5 dedicated tests:

1. envelope.command ↔ dispatched subcommand
2. envelope.output_format ↔ --output-format flag
3. envelope.timestamp ↔ actual wall clock (recent, <5s)
4. envelope.exit_code ↔ process exit code (cycle #26/#181 regression guard)
5. envelope boolean fields (found/handled/deleted) ↔ error block presence

Each test specifically targets cross-channel truth, not structure or quality.

## Why Separate Test Classes Matter

A command can fail all three ways independently:

| Failure mode | Exit/Crash | Test class | Example |
|---|---|---|---|
| Structural | stderr noise | TestParseErrorEnvelope | argparse leaks to stderr |
| Quality | correct shape, wrong message | TestParseErrorStderrHygiene | error instead of real message |
| Cross-channel | truthy field, lie about state | TestCrossChannelConsistency | exit_code: 0 but exit 1 |

#181 was invisible to the first two classes. A claw passing all structure/
quality tests could still be misled. The third class catches that.

## Audit Results (Cycle #27)

All 5 tests pass — no drift detected in any channel pair:

-  Envelope command always matches dispatch
-  Envelope output_format always matches flag
-  Envelope timestamp always recent (<5s)
-  Envelope exit_code always matches process exit (post-#181 guard)
-  Boolean fields consistent with error block presence

The systematic audit proved the fix from #181 holds, and identified
no new cross-channel gaps.

## Test Impact

- 209 → 214 tests passing (+5)
- Zero regressions
- New invariant class now has dedicated test suite
- Future cross-channel bugs will be caught by this class

## Related

- #178 (#20): Parser-front-door structural contract
- #179 (#20): Stderr hygiene + real error message quality
- #181 (#26): Envelope exit_code must match process exit
- #182-N: Future cross-channel contract violations will be caught
  by TestCrossChannelConsistency

This test class is evergreen — as new fields/channels are added to the
protocol, invariants for those channels should be added here, not mixed
with other test classes. Keeping invariant classes separate makes
regression attribution instant (e.g., 'TestCrossChannelConsistency failed'
= 'some truth channel disagreed').

- Red-state bug: ✗ (audit is green)
- Real friction: ✓ (structured audit of documented invariants)

YeonGyu-Kim 6a2a2c4d58 fix: #181 — envelope exit_code must match process exit code (exec-command/exec-tool)
Cycle #26 dogfood found a real red-state bug in the JSON envelope contract.

## The Bug

exec-command and exec-tool not-found cases return exit code 1 from the
process, but the envelope reports exit_code: 0 (the default from
wrap_json_envelope). This is a protocol violation.

Repro (before fix):
  $ claw exec-command unknown-cmd test --output-format json > out.json
  $ echo $?
  1
  $ jq '.exit_code' out.json
  0  # WRONG — envelope lies about exit code

Claws reading the envelope's exit_code field get misinformation. A claw
implementing the canonical ERROR_HANDLING.md pattern (check exit_code,
then classify by error.kind) would incorrectly treat failures as
successes when dispatching on the envelope alone.

## Root Cause

main.py lines 687–739 (exec-command + exec-tool handlers):
- Return statement: 'return 0 if result.handled else 1' (correct)
- Envelope wrap: 'wrap_json_envelope(envelope, args.command)'
  (uses default exit_code=0, IGNORES the return value)

The envelope wrap was called BEFORE the return value was computed, so
the exit_code field was never synchronized with the actual exit code.

## The Fix

Compute exit_code ONCE at the top:
  exit_code = 0 if result.handled else 1

Pass it explicitly to wrap_json_envelope:
  wrap_json_envelope(envelope, args.command, exit_code=exit_code)

Return the same value:
  return exit_code

This ensures the envelope's exit_code field is always truth — the SAME
value the process returns.

## Tests Added (3)

TestEnvelopeExitCodeMatchesProcessExit in test_exec_route_bootstrap_output_format.py:

1. test_exec_command_not_found_envelope_exit_matches:
   Verifies exec-command unknown-cmd returns exit 1 in both envelope
   and process.

2. test_exec_tool_not_found_envelope_exit_matches:
   Same for exec-tool.

3. test_all_commands_exit_code_invariant:
   Audit across 4 known non-zero cases (show-command, show-tool,
   exec-command, exec-tool not-found). Guards against the same bug
   in other surfaces.

## Impact

- 206 → 209 passing tests (+3)
- Zero regressions
- Protocol contract now truthful: envelope.exit_code == process exit
- Claws using the one-handler pattern from ERROR_HANDLING.md now get
  correct information

YeonGyu-Kim 9844f9251f docs: USAGE.md — cross-link ERROR_HANDLING.md for subprocess orchestration
Cycle #25 ships navigation improvements connecting USAGE (setup/interactive)
to ERROR_HANDLING.md (subprocess/orchestration patterns).

Before: USAGE.md had JSON scripting mention but no link to error-handling guide.
New users reading USAGE would see JSON is available, but wouldn't discover
the error-handling pattern without accidentally finding ERROR_HANDLING.md.

After: Two strategic cross-links:
1. Top-level tip box: "Building orchestration code? See ERROR_HANDLING.md"
2. JSON scripting section expanded with examples + link to unified pattern

Changes to USAGE.md:
- Added TIP callout near top linking to ERROR_HANDLING.md
- Expanded "JSON output for scripting" section:
  - Explains what the envelope contains (exit_code, command, timestamp, fields)
  - Added 3 command examples (prompt, load-session, turn-loop)
  - Added callout for dispatchers/orchestrators pointing to ERROR_HANDLING pattern

Impact: Operators reading USAGE for "how do I call claw from scripts?" now
immediately see the canonical answer (ERROR_HANDLING.md) instead of having
to reverse-engineer it from code examples.

No code changes. Pure navigation/documentation.

Continues the documentation-governance pattern: the work protocol (14 clawable
commands) has a consumption guide (ERROR_HANDLING.md), and that guide is now
reachable from the main entry point (USAGE.md + README.md top nav).

YeonGyu-Kim 7fad212976 docs: README.md — promote ERROR_HANDLING.md to first-class navigation
Cycle #23 ships a documentation discoverability fix.

After #22 shipping ERROR_HANDLING.md, the next natural step is making it
discoverable from the project's entry point (README.md).

Before: README top navigation linked to USAGE, PARITY, ROADMAP, Rust workspace.
ERROR_HANDLING.md was buried in CLAUDE.md references.

After: ERROR_HANDLING.md is now in the top navigation (right after USAGE,
before Rust workspace). Also added SCHEMAS.md mention in repository shape.

This signals that:
1. Error handling is a first-class concern (not an afterthought)
2. The Python harness documentation (SCHEMAS.md, ERROR_HANDLING.md, CLAUDE.md)
   is part of the official docs, not just dogfood artifacts
3. New users/claws can discover the error-handling pattern at entry point

Impact: Operators building orchestration code will immediately see
'Error Handling' link in navigation, shortening the path to understanding
how to consume the protocol reliably.

No code changes. No test changes. Pure navigation/discoverability.

YeonGyu-Kim 018e1f9b5a docs: ERROR_HANDLING.md — unified error handler pattern for orchestration code
Cycle #22 ships documentation that operationalizes cycles #178–#179.

Problem context:
After #178 (parse-error envelope) and #179 (stderr hygiene + real error message),
claws can now build a unified error handler for all 14 clawable commands.
But there was no guide on how to actually do that. Operators had the pieces;
they didn't have the pattern.

This file changes that.

New file: ERROR_HANDLING.md
- Quick reference: exit codes + envelope shapes (0=success, 1=error, 2=timeout)
- One-handler pattern: ~80 lines of Python showing how to parse error.kind,
  check retryable, and decide recovery strategy
- Four practical recovery patterns:
  - Retry on transient errors (filesystem, timeout)
  - Reuse session after timeout (if cancel_observed=true)
  - Validate command syntax before dispatch (dry-run --help)
  - Log errors for observability
- Error kinds enumeration (parse, session_not_found, filesystem, runtime, timeout)
- Common mistakes to avoid (6 patterns with BAD vs GOOD examples)
- Testing your error handler (unit test examples)

Operational impact:
Orchestration code now has a canonical pattern. Claws can:
- Copy-paste the run_claw_command() function (works for all commands)
- Classify errors uniformly (no special cases per command)
- Decide recovery deterministically (error.kind + retryable + cancel_observed)
- Log/monitor/escalate with confidence

YeonGyu-Kim 28c55b28b6 docs: OPT_OUT_DEMAND_LOG.md — evidentiary base for governance decisions
Cycle #21 ships governance infrastructure, not implementation. Maintainership
mode means sometimes the right deliverable is a decision framework, not code.

Problem context:
OPT_OUT_AUDIT.md (cycle #18 bonus) established 'demand-backed audit' as the
next step. But without a structured way to record demand signals, 'demand-backed'
was just a slogan — the next audit cycle would have no evidence to work from.

This commit creates the evidentiary base:

New file: OPT_OUT_DEMAND_LOG.md
- Per-surface entries for all 12 OPT_OUT commands (Groups A/B/C)
- Current state: 0 signals across all surfaces (consistent with audit prediction)
- Signal entry template with required fields:
  - Source (who/what)
  - Use case (concrete orchestration problem)
  - Markdown-alternative-checked (why existing output insufficient)
  - Date
- Promotion thresholds:
  - 2+ independent signals for same surface → file promotion pinpoint
  - 1 signal + existing stable schema → file pinpoint for discussion
  - 0 signals → stays OPT_OUT (rationale preserved)

Decision framework for cycle #22 (audit close):
- If 0 signals total: move to PERMANENTLY_OPT_OUT, close audit
- If 1-2 signals: file individual promotion pinpoints with evidence
- If 3+ signals: reopen audit, question classification itself

Updated files:
- OPT_OUT_AUDIT.md: Added demand log reference in Related section
- CLAUDE.md: Added prerequisites for promotions (must have logged signals),
  added 'File a demand signal' workflow section

Philosophy:
'Prevent speculative expansion' — schema bloat protection discipline.
Every new CLAWABLE surface is a maintenance tax. Evidence requirement keeps
the protocol lean. OPT_OUT surfaces are intentionally not-clawable until
proven otherwise by external demand.

Operational impact:
Next cycles can now:
1. Watch for real claws hitting OPT_OUT surface limits
2. Log signals in structured format (no ad-hoc filing)
3. Run audit at cycle #22 with actual data, not speculation

No code changes. No test changes. Pure governance infrastructure.

Related: #18 cycle (OPT_OUT_AUDIT.md), maintainership phase transition.

YeonGyu-Kim 375860cbde fix: #179 — JSON mode now fully suppresses argparse stderr + preserves real error message
Dogfood discovered #178 had two residual gaps:

1. Stderr pollution: argparse usage + error text still leaked to stderr even in
   JSON mode (envelope was correct on stdout, but stderr noise broke the
   'machine-first protocol' contract — claws capturing both streams got dual output)

2. Generic error message: envelope carried 'invalid command or argument (argparse
   rejection)' instead of argparse's actual text like 'the following arguments
   are required: session_id' or 'invalid choice: typo (choose from ...)'

Before #179:
  $ claw load-session --output-format json
  [stdout] {"error": {"message": "invalid command or argument (argparse rejection)"}}
  [stderr] usage: main.py load-session [-h] ...
           main.py load-session: error: the following arguments are required: session_id
  [exit 1]

After #179:
  $ claw load-session --output-format json
  [stdout] {"error": {"message": "the following arguments are required: session_id"}}
  [stderr] (empty)
  [exit 1]

Implementation:
- New _ArgparseError exception class captures argparse's real message
- main() monkey-patches parser.error (+ all subparser.error) in JSON mode to raise
  _ArgparseError instead of print-to-stderr + sys.exit(2)
- _emit_parse_error_envelope() now receives the real message verbatim
- Text mode path unchanged: still uses original argparse print+exit behavior

Contract:
- JSON mode: stdout carries envelope with argparse's actual error; stderr silent
- Text mode: unchanged — argparse usage to stderr, exit 2
- Parse errors still error.kind='parse', retryable=false

Test additions (5 new, 14 total in test_parse_error_envelope.py):
- TestParseErrorStderrHygiene (5):
  - test_json_mode_stderr_is_silent_on_unknown_command
  - test_json_mode_stderr_is_silent_on_missing_arg
  - test_json_mode_envelope_carries_real_argparse_message
  - test_json_mode_envelope_carries_invalid_choice_details (verifies valid-choices list)
  - test_text_mode_stderr_preserved_on_unknown_command (backward compat)

Operational impact:
Claws capturing both stdout and stderr no longer get garbled output. The envelope
message now carries discoverability info (valid command list, missing-arg name)
that claws can use for retry/recovery without probing the CLI a second time.

Test results: 201 → 206 passing, 3 skipped unchanged, zero regression.

YeonGyu-Kim 39769a3863 feat: #178 — argparse errors emit JSON envelope when --output-format json requested
Dogfood pinpoint: running 'claw nonexistent-command --output-format json' bypasses
the JSON envelope contract — argparse dumps human-readable usage to stderr with
exit 2, breaking the SCHEMAS.md guarantee that JSON mode returns structured output.

Problem:
  $ claw nonexistent --output-format json
  usage: main.py [-h] {summary,manifest,...} ...
  main.py: error: argument command: invalid choice: 'nonexistent' (choose from ...)
  [exit 2 — no envelope, claws must parse argparse usage messages]

Fix:
  $ claw nonexistent --output-format json
  {
    "timestamp": "2026-04-22T11:00:29Z",
    "command": "nonexistent-command",
    "exit_code": 1,
    "output_format": "json",
    "schema_version": "1.0",
    "error": {
      "kind": "parse",
      "operation": "argparse",
      "target": "nonexistent-command",
      "retryable": false,
      "message": "invalid command or argument (argparse rejection)",
      "hint": "run with no arguments to see available subcommands"
    }
  }
  [exit 1, clean JSON envelope on stdout per SCHEMAS.md]

Changes:
- src/main.py:
  - _wants_json_output(argv): pre-scan for --output-format json before parsing
  - _emit_parse_error_envelope(argv, message): emit wrapped envelope on stdout
  - main(): catch SystemExit from argparse; if JSON requested, emit envelope
    instead of letting argparse's help dump go through

- tests/test_parse_error_envelope.py (new, 9 tests):
  - TestParseErrorJsonEnvelope (7): unknown command, =syntax, text mode unchanged,
    invalid flag, missing command, valid command unaffected, common fields
  - TestParseErrorSchemaCompliance (2): error.kind='parse', retryable=false

Contract:
- text mode (default): unchanged — argparse dumps help to stderr, exits 2
- JSON mode: envelope per SCHEMAS.md, error.kind='parse', exit 1
- Parse errors always retryable=false (typo won't self-fix)
- error.kind='parse' already enumerated in SCHEMAS.md (no schema changes)

This closes a real gap: claws invoking unknown commands in JSON mode can now route
via exit code + envelope.kind='parse' instead of scraping argparse output.

Test results: 192 → 201 passing, 3 skipped unchanged, zero regression.

YeonGyu-Kim ea0a832d8a docs: OPT_OUT_AUDIT.md — decision table for 12 exempt surfaces (#175–#177 prep)
Filed explicit decision criteria for the 12 OPT_OUT surfaces (commands that do
not support --output-format json) documented in test_cli_parity_audit.py.

Categorized by rationale:
- Group A (4): Rich-Markdown reports (summary, manifest, parity-audit, setup-report)
  Markdown-as-output is intentional; JSON would be information loss.
  Unlikely promotions (remain OPT_OUT long-term).

- Group B (3): List filters with --query/--limit (subsystems, commands, tools)
  Query layer already exists; users have escape hatch.
  Remain OPT_OUT (promotion effort >> value).

- Group C (5): Simulation/debug surfaces (remote-mode, ssh-mode, teleport-mode,
  direct-connect-mode, deep-link-mode)
  Intentionally non-production; JSON output doesn't add value.
  Remain OPT_OUT (simulation tools, not orchestration endpoints).

Audit workflow documented:
1. Survey: Check if external claws actually request JSON versions
2. Cost estimate: Schema + tests for each surface
3. Value estimate: Real demand vs hypothetical
4. Decision: CLAWABLE, remain OPT_OUT, or new pinpoint

Promotion criteria locked (only if clear use case + schema simple + demand exists).

Outcome prediction: All 12 likely remain OPT_OUT (documented rationale per group).

Timeline: Survey period (cycles #19–#21), final decision (cycle #22).

Related pinpoints: #175 (summary/manifest JSON parallel?), #176 (--query-json?),
#177 (mode simulators ever CLAWABLE?).

This closes the documentation loop from cycles #173–#174 (protocol closure →
field evolution → reframe). Now governance rules are explicit for future work.

YeonGyu-Kim c12634f16e docs: CLAUDE.md reframe — market Python harness as machine-first protocol validation layer
Rewrote CLAUDE.md to accurately describe the Python reference implementation:
- Shifted framing from outdated Rust-focused guidance to protocol-validation focus
- Clarified that src/tests/ is a dogfood surface proving SCHEMAS.md contract
- Added machine-first marketing: deterministic, self-describing, clawable
- Documented all 14 clawable commands (post-#164 Stage B promotion)
- Added OPT_OUT surfaces audit queue (12 commands, future work)
- Included protocol layers: Coverage → Enforcement → Documentation → Alignment
- Added quick-start workflow for Python harness
- Documented common workflows (add command, modify fields, promote OPT_OUT→CLAWABLE)
- Emphasized protocol governance: SCHEMAS.md as source of truth
- Exit codes documented as signals (0=success, 1=error, 2=timeout)

Result: Developers can now understand the Python harness purpose without reading
ROADMAP.md or inferring from test names. Protocol-first mental model is explicit.

YeonGyu-Kim 7dd9a644cd feat: #164 Stage B CLOSURE — turn-loop JSON + cancel_observed coverage + CLAWABLE promotion
Closes all three gaebal-gajae-identified closure criteria for #164 Stage B:

1. turn-loop runtime surface exposes cancel_observed consistently
2. cancellation path tests validate safe-to-reuse semantics
3. turn-loop promoted from OPT_OUT to CLAWABLE surface

Changes:

src/main.py:
- turn-loop accepts --output-format {text,json}
- JSON envelope includes per-turn cancel_observed + final_cancel_observed
- All turn fields exposed: prompt, output, stop_reason, cancel_observed,
  matched_commands, matched_tools
- Exit code 2 on final timeout preserved

tests/test_cli_parity_audit.py:
- CLAWABLE_SURFACES now contains 14 commands (was 13)
- Removed 'turn-loop' from OPT_OUT_SURFACES
- Parametrized --output-format test auto-validates turn-loop JSON

tests/test_cancel_observed_field.py (new, 9 tests):
- TestCancelObservedField (5 tests): field contract
  - default False
  - explicit True preserved
  - normal completion → False
  - bootstrap JSON exposes field
  - turn-loop JSON exposes per-turn field
- TestCancelObservedSafeReuseSemantics (2 tests): reuse contract
  - timeout result has cancel_observed=True when signaled
  - engine.mutable_messages not corrupted after cancelled turn
  - engine accepts fresh message after cancellation
- TestCancelObservedSchemaCompliance (2 tests): SCHEMAS.md contract
  - cancel_observed is always bool
  - final_cancel_observed convenience field present

Closure criteria validated:
-  Field exposed in bootstrap JSON
-  Field exposed per-turn in turn-loop JSON
-  Field is always bool, never null
-  Safe-to-reuse: engine can accept fresh messages after cancellation
-  mutable_messages not corrupted by cancelled turn
-  turn-loop promoted from OPT_OUT (14 clawable commands now)

Protocol now distinguishes at runtime:
  timeout + cancel_observed=false → infra/wedge (escalate)
  timeout + cancel_observed=true → cooperative cancellation (safe to retry)

Test results: 182 → 192 passing, +10 tests, zero regression, 3 skipped unchanged.

Closes #164 Stage B. Stage C (async-native preemption) remains future work.

YeonGyu-Kim e6ad87041c feat: #164 Stage B prep — add cancel_observed field to TurnResult
#164 Stage B requires exposing whether cancellation was observed at the
turn-result level. This commit adds the infrastructure field:

Changes:
- TurnResult.cancel_observed: bool = False (query_engine.py)
- _build_timeout_result() accepts cancel_observed parameter (runtime.py)
- Two timeout paths now pass cancel_event.is_set() to signal observation (runtime.py)
- bootstrap command includes cancel_observed in turn JSON (main.py)
- SCHEMAS.md documents Turn Result Fields with cancel_observed contract

Usage:
  When a turn timeout occurs, cancel_observed=true indicates that the
  engine observed the cancellation event being set. This allows callers
  to distinguish:
    - timeout with no cancel → infrastructure/network stall
    - timeout with cancel observed → cooperative cancellation was triggered

Backward compat:
  - Existing TurnResult construction without cancel_observed defaults to False
  - bootstrap JSON output still validates per SCHEMAS.md (new field is always present)

Test results: 182 passing, 3 skipped, zero regression.

YeonGyu-Kim fd174034ee feat: #173 — wrap_json_envelope() applied to all 13 clawable commands (LOOP CLOSED)
Completes the coverage → enforcement → documentation → alignment cycle.
Every clawable command now emits the canonical JSON envelope per SCHEMAS.md:

Common fields (now real in output):
  - timestamp (ISO 8601 UTC)
  - command (argv[1])
  - exit_code (0/1/2)
  - output_format ('json')
  - schema_version ('1.0')

13 commands wrapped:
  - list-sessions, delete-session, load-session, flush-transcript
  - show-command, show-tool
  - exec-command, exec-tool, route, bootstrap
  - command-graph, tool-pool, bootstrap-graph

Implementation:
- Added wrap_json_envelope() helper in src/main.py
- Wrapped all 18 JSON output paths (13 success + 5 error paths)
- Applied exit_code=1 to error/not-found envelopes
- Kept text mode byte-identical (backward compat preserved)

Test updates:
- 3 skipped common-field tests now pass automatically
- 3 existing tests updated to verify common envelope fields while preserving command-specific field checks
- test_list_sessions_cli_runs, test_delete_session_cli_idempotent,
  test_load_session_cli::test_json_mode_on_success

Full suite: 179 → 182 passing (+3 activated from skipped), zero regression.

Loop completion:
  Coverage (#167-#170)        All 13 commands accept --output-format
  Enforcement (#171)          CI blocks new commands without --output-format
  Documentation (#172)        SCHEMAS.md defines envelope contract
  Alignment (#173 this)       Actual output matches SCHEMAS.md contract

Example output now:
  $ claw list-sessions --output-format json
  {
    "timestamp": "2026-04-22T10:34:12Z",
    "command": "list-sessions",
    "exit_code": 0,
    "output_format": "json",
    "schema_version": "1.0",
    "sessions": ["alpha", "bravo"],
    "count": 2
  }

Closes ROADMAP #173. Protocol is now documented AND real.
Claws can build ONE error handler, ONE timestamp parser, ONE version check
instead of 13 special cases.

YeonGyu-Kim d2a1fe7259 test: #173 prep — JSON envelope field consistency validation
Adds parametrised test suite validating that clawable-surface commands'
JSON output matches their declared envelope contracts per SCHEMAS.md.

Two phases:

Phase 1 (this commit): Consistency baseline.
  - Collect ENVELOPE_CONTRACTS registry mapping each command to its
    required and optional fields
  - TestJsonEnvelopeConsistency: parametrised test iterates over 13
    commands, invokes with --output-format json, validates that
    actual JSON envelope contains all required fields
  - test_envelope_field_value_types: spot-check types (int, str, list)
    for consistency

Phase 2 (future #173): Common field wrapping.
  - Once wrap_json_envelope() is applied, all commands will emit
    timestamp, command, exit_code, output_format, schema_version
  - Currently skipped via @pytest.mark.skip, these tests will activate
    automatically when wrapping is implemented:
      TestJsonEnvelopeCommonFieldPrep::test_all_envelopes_include_timestamp
      TestJsonEnvelopeCommonFieldPrep::test_all_envelopes_include_command
      TestJsonEnvelopeCommonFieldPrep::test_all_envelopes_include_exit_code_and_schema_version

Why this matters:
  - #172 documented the JSON contract; this test validates it
  - Currently detects when actual output diverges from SCHEMAS.md
    (e.g. list-sessions emits 'count', not 'sessions_count')
  - As #173 wraps commands, test suite auto-validates new common fields
  - Prevents regression: accidental field removal breaks the test suite

Current status: 11 passed (consistency), 6 skipped (awaiting #173)
Full suite: 168 → 179 passing, zero regression.

Closes ROADMAP #173 prep (framework for common field validation).
Actual field wrapping remains for next cycle.

YeonGyu-Kim 0e9ad485f3 docs: add SCHEMAS.md — field-level JSON contract for clawable CLI surfaces
Documents the unified JSON envelope contract across all 13 clawable-surface
commands. Extends the parity work (#171) to the field level: every command
that accepts --output-format json must emit predictable field names,
types, and optionality.

Common fields (all envelopes):
  - timestamp (ISO 8601 UTC)
  - command (argv[1])
  - exit_code (0/1/2)
  - output_format ('json')
  - schema_version ('1.0')

Error envelope (exit 1, failure):
  - error.kind (enum: filesystem|auth|session|parse|runtime|mcp|delivery|usage|policy|unknown)
  - error.operation (syscall/method name)
  - error.target (resource path/name)
  - error.retryable (bool)
  - error.message (platform error text)
  - error.hint (optional: actionable next step)

Not-found envelope (exit 1, not a failure):
  - found: false
  - error.kind (enum: command_not_found|tool_not_found|session_not_found)
  - error.message, error.retryable

Per-command success schemas documented for 13 commands:
  list-sessions, delete-session, load-session, flush-transcript,
  show-command, show-tool, exec-command, exec-tool, route, bootstrap,
  command-graph, tool-pool, bootstrap-graph

Why this matters:
- #171 enforced that commands have --output-format; #172 enforces that
  the JSON fields are PREDICTABLE
- Downstream claws can build ONE error handler + per-command jq query,
  not special-casing logic per command family
- Field consistency enables generic automation patterns (error dedupe,
  failure aggregation, cross-command monitoring)

- ROADMAP #171 (parity audit CI automation — already landed)
- #164 Stage B (cancellation observability — adds cancel_observed field)
- #164 Stage A (already done — adds stop_reason field to TurnResult)

- Consistency test: test_json_envelope_field_consistency.py (future)
- Versioning: schema_version='1.0' for current; bump to 2.0 for breaking changes

YeonGyu-Kim 9fa6f27eaa fix: #171 — automate cross-surface CLI parity audit via argparse introspection
Stops manual parity inspection from being a human-noticed concern. When
a developer adds a new subcommand to the claw-code CLI, this test suite
enforces explicit classification:
  - CLAWABLE_SURFACES: MUST accept --output-format {text,json}
  - OPT_OUT_SURFACES: explicitly exempt with documented rationale

A new command that forgets to opt into one of these two sets FAILS
loudly with TestCommandClassificationCoverage::test_every_registered_
command_is_classified. No silent drift possible.

Technique: argparse introspection at test time walks the _actions tree,
discovers every registered subcommand, and compares against the declared
classification sets. Contract is enforced machine-first instead of
depending on human review.

Three test classes covering three invariants:

TestClawableSurfaceParity (14 tests):
  - test_all_clawable_surfaces_accept_output_format: every member of
    CLAWABLE_SURFACES has --output-format flag registered
  - test_clawable_surface_output_format_choices (parametrised over 13
    commands): each must accept exactly {text, json} and default to 'text'
    for backward compat

TestCommandClassificationCoverage (3 tests):
  - test_every_registered_command_is_classified: any new subcommand
    must be explicitly added to CLAWABLE_SURFACES or OPT_OUT_SURFACES
  - test_no_command_in_both_sets: sanity check for classification conflicts
  - test_all_classified_commands_actually_exist: no phantom commands
    (catches stale entries after a command is removed)

TestJsonOutputContractEndToEnd (10 tests):
  - test_command_emits_parseable_json (parametrised over 10 clawable
    commands): actual subprocess invocation with --output-format json
    produces valid parseable JSON on stdout

Classification:
  CLAWABLE_SURFACES (13):
    Session lifecycle: list-sessions, delete-session, load-session,
                       flush-transcript
    Inspect: show-command, show-tool
    Execution: exec-command, exec-tool, route, bootstrap
    Diagnostic inventory: command-graph, tool-pool, bootstrap-graph

  OPT_OUT_SURFACES (12):
    Rich-Markdown reports (future JSON schema): summary, manifest,
                         parity-audit, setup-report
    List filter commands: subsystems, commands, tools
    Turn-loop: structured_output is future work
    Simulation/debug: remote-mode, ssh-mode, teleport-mode,
                      direct-connect-mode, deep-link-mode

Full suite: 141 → 168 passing (+27), zero regression.

Closes ROADMAP #171.

Why this matters:
  Before: parity was human-monitored; every new command was a drift
          risk. The CLUSTER 3 sweep required manually auditing every
          subcommand and landing fixes as separate pinpoints.
  After: parity is machine-enforced. If a future developer adds a new
         command without --output-format, the test suite blocks it
         immediately with a concrete error message pointing at the
         missing flag.

This is the first step in Gaebal-gajae's identified upper-level work:
operationalised parity instead of aspirational parity.

  - Clawability principle: machine-first protocol enforcement
  - Test-first regression guard: extends TestTripletParityConsistency

YeonGyu-Kim c0e2ff9ad8 fix: #170 — bootstrap-graph now accepts --output-format; diagnostic surface parity complete
Final diagnostic surface in the JSON parity sweep: bootstrap-graph
(the runtime bootstrap/prefetch visualization) now supports --output-format.

Concrete addition:
- bootstrap-graph: --output-format {text,json}

JSON envelope:
  {stages: [str], note: 'bootstrap-graph is markdown-only in this version'}

Envelope explanation: bootstrap-graph's Markdown output is rich and
textual; raw JSON embedding maintains the markdown format (split into
lines array) rather than attempting lossy structural extraction that
would lose information. This is an honest limitation in this cycle;
full JSON schema can be added in a future audit if claws require
structured bootstrap data (dependency graphs, prefetch timing, etc.).

Backward compatibility:
  - Default is 'text' (Markdown unchanged)

Closes ROADMAP #170.

Related: #167, #168, #169. Diagnostic/inventory surface family is now
uniformly JSON-capable. Summary, manifest, parity-audit, setup-report,

YeonGyu-Kim b06bf2df27 fix: #169 — command-graph and tool-pool now accept --output-format; diagnostic inventory JSON parity
Extends the diagnostic surface audit with the two inventory-structure
commands: command-graph (command family segmentation) and tool-pool
(assembled tool inventory). Both now expose their underlying rich
datastructures via JSON envelope.

Concrete additions:
- command-graph: --output-format {text,json}
- tool-pool: --output-format {text,json}

JSON envelope shapes:

command-graph:
  {builtins_count, plugin_like_count, skill_like_count, total_count,
   builtins: [{name, source_hint}],
   plugin_like: [{name, source_hint}],
   skill_like: [{name, source_hint}]}

tool-pool:
  {simple_mode, include_mcp, tool_count,
   tools: [{name, source_hint}]}

Backward compatibility:
  - Default is 'text' (Markdown unchanged)
  - Text output byte-identical to pre-#169

Tests (4 new, test_command_graph_tool_pool_output_format.py):
  - TestCommandGraphOutputFormat (2): JSON structure + text compat
  - TestToolPoolOutputFormat (2): JSON structure + text compat

Full suite: 137 → 141 passing, zero regression.

Closes ROADMAP #169.

Why this matters:
  Claws auditing the codebase can now ask 'what commands exist' and
  'what tools exist' and get structured, parseable answers instead of
  regex-parsing Markdown headers and counting list items.

outliers: the commands claws actually invoke to DO work, not just
inspect state. After this commit, the entire claw-code CLI family speaks

Closes ROADMAP #168.

This completes the CLI-wide JSON parity sweep:
- Session-lifecycle family: #160 (list/delete), #165 (load), #166 (flush)
- Inspect family: #167 (show-command, show-tool)
- Work-verb family: #168 (exec-command, exec-tool, route, bootstrap)

ENTIRE CLI SURFACE is now machine-readable via --output-format json with
typed errors, deterministic exit codes, and consistent envelope shape.
Claws no longer need to regex-parse any CLI output.

Related clusters:
  - Clawability principle: 'machine-readable in state and failure modes'
    (ROADMAP top-level). 9 pinpoints in this cluster; all now landed.
  - Typed-error envelope consistency: command_not_found / tool_not_found /
    session_not_found / session_load_failed all share {kind, message,
    retryable} shape.
  - Work-verb semantics: exec-* surfaces expose 'handled' boolean (not
    'found') because 'not handled' is the operational signal — claws
    dispatch on whether the work was performed, not whether the entry
    exists in the inventory.

YeonGyu-Kim bd59968425 fix: #167 — show-command and show-tool now accept --output-format flag; CLI parity with session-lifecycle family
Closes the inspect-capability parity gap: show-command and show-tool were
the only discovery/inspection CLI commands lacking --output-format support,
making them outliers in the ecosystem that already had unified JSON
contracts across list-sessions, load-session, delete-session, and
flush-transcript (#160/#165/#166).

Concrete additions:

- show-command: --output-format {text,json}
- show-tool: --output-format {text,json}

JSON envelope shape (found case):
  {name, found: true, source_hint, responsibility}

JSON envelope shape (not-found case):
  {name, found: false, error: {kind:'command_not_found'|'tool_not_found',
                               message, retryable: false}}

Exit codes:
  0 = success
  1 = not found

Backward compatibility:
  - Default (no --output-format) is 'text' (unchanged)
  - Text output byte-identical to pre-#167 (three newline-separated lines)

Tests (10 new, test_show_command_tool_output_format.py):
  - TestShowCommandOutputFormat (5): found + not-found in JSON; text mode
    backward compat; text is default
  - TestShowToolOutputFormat (3): found + not-found in JSON; text mode
    backward compat
  - TestShowCommandToolFormatParity (2): both accept same flag choices;
    consistent JSON envelope shape

Full suite: 114 → 124 passing, zero regression.

Closes ROADMAP #167.

Why this matters:
  Before: Claws calling show-command/show-tool had to parse human-readable
  prose output via regex, with no structured error signal.
  After: Same envelope contract as load-session and friends: JSON-first,
  typed errors, machine-parseable.

Related clusters:
  - Session-lifecycle CLI parity family (#160, #165, #166, #167)
  - Machine-readable error contracts (same vein as #162 atomicity + #164

YeonGyu-Kim 3415278994 fix: #164 Stage A — cooperative cancellation via cancel_event in submit_message
Closes the #161 follow-up gap identified in review: wall-clock timeout
bounded caller-facing wait but did not cancel the underlying provider
thread, which could silently mutate mutable_messages / transcript_store /
permission_denials / total_usage after the caller had already observed
stop_reason='timeout'. A ghost turn committed post-deadline would poison
any session that got persisted afterwards.

Stage A scope (this commit): runtime + engine layer cooperative cancel.

Engine layer (src/query_engine.py):
- submit_message now accepts cancel_event: threading.Event | None = None
- Two safe checkpoints:
  1. Entry (before max_turns / budget projection) — earliest possible return
  2. Post-budget (after output synthesis, before mutation) — catches cancel
     that arrives while output was being computed
- Both checkpoints return stop_reason='cancelled' with state UNCHANGED
  (mutable_messages, transcript_store, permission_denials, total_usage
  all preserved exactly as on entry)
- cancel_event=None preserves legacy behaviour with zero overhead (no
  checkpoint checks at all)

Runtime layer (src/runtime.py):
- run_turn_loop creates one cancel_event per invocation when a deadline
  is in play (and None otherwise, preserving legacy fast path)
- Passes the same event to every submit_message call across turns, so a
  late cancel on turn N-1 affects turn N
- On timeout (either pre-call or mid-call), runtime explicitly calls
  cancel_event.set() before future.cancel() + synthesizing the timeout
  TurnResult. This upgrades #161's best-effort future.cancel() (which
  only cancels not-yet-started futures) to cooperative mid-flight cancel.

Stop reason taxonomy after Stage A:
  'completed'           — turn committed, state mutated exactly once
  'max_budget_reached'  — overflow, state unchanged (#162)
  'max_turns_reached'   — capacity exceeded, state unchanged
  'cancelled'           — cancel_event observed, state unchanged (#164 Stage A)
  'timeout'             — synthesised by runtime, not engine (#161)

The 'cancelled' vs 'timeout' split matters:
- 'timeout' is the runtime's best-effort signal to the caller: deadline hit
- 'cancelled' is the engine's confirmation: cancel was observed + honoured

If the provider call wedges entirely (never reaches a checkpoint), the
caller still sees 'timeout' and the thread is leaked — but any NEXT
submit_message call on the same engine observes the event at entry and
returns 'cancelled' immediately, preventing ghost-turn accumulation.
This is the honest cooperative limit in Python threading land; true
preemption requires async-native provider IO (future work, not Stage A).

Tests (29 new tests, tests/test_submit_message_cancellation.py + tests/
test_run_turn_loop_cancellation.py):

Engine-layer (12 tests):
- TestCancellationBeforeCall (5): pre-set event returns 'cancelled' immediately;
  mutable_messages, transcript_store, usage, permission_denials all preserved
- TestCancellationAfterBudgetCheck (1): cancel set mid-call (after projection,
  before commit) still honoured; output synthesised but state untouched
- TestCancellationAfterCommit (2): post-commit cancel not observable (honest
  limit) BUT next call on same engine observes it + returns 'cancelled'
- TestLegacyCallersUnchanged (3): cancel_event=None preserves #162 atomicity
  + max_turns contract with zero behaviour change
- TestCancellationVsOtherStopReasons (2): cancel precedes max_turns check;
  cancel does not retroactively override a completed turn

Runtime-layer (5 tests):
- TestTimeoutPropagatesCancelEvent (3): submit_message receives a real Event
  object when deadline is set; None in legacy mode; timeout actually calls
  event.set() so in-flight threads observe at their next checkpoint
- TestCancelEventSharedAcrossTurns (1): same event object passed to every
  turn (object identity check) — late cancel on turn N-1 must affect turn N

Regression: 3 existing timeout test mocks updated to accept cancel_event
kwarg (mocks that previously had signature (prompt, commands, tools, denials)
now have (prompt, commands, tools, denials, cancel_event=None) since runtime
passes cancel_event positionally on the timeout path).

Full suite: 97 → 114 passing, zero regression.

Closes ROADMAP #164 Stage A.

What's explicitly NOT in Stage A:
- Preemptive cancellation of wedged provider IO (requires asyncio-native
  provider path; larger refactor)
- Timeout on the legacy unbounded run_turn_loop path (by design: legacy
  callers opt out of cancellation entirely)
- CLI exposure of 'cancelled' as a distinct exit code (currently 'cancelled'
  maps to the same stop_reason != 'completed' break condition as others;
  CLI surface for cancel is a separate pinpoint if warranted)

YeonGyu-Kim db43d166e9 chore: gitignore .port_sessions/ to prevent dogfood-run pollution
Every 'claw flush-transcript' call without --directory writes to
.port_sessions/<uuid>.json in CWD. Without a gitignore entry, every
dogfood run leaves dozens of untracked files in the repo, masking real
changes in 'git status' output.

Now that #160/#166 ship structured session lifecycle commands and
deterministic --session-id, this directory is purely transient by
default — belongs in .gitignore.

YeonGyu-Kim 753c22e2cd fix: #159 — run_turn_loop no longer hardcodes empty denied_tools; permission denials now parity-match bootstrap_session
#159: multi-turn sessions had a silent security asymmetry: denied_tools
were always empty in run_turn_loop, even though bootstrap_session inferred
them from the routed matches. Result: any tool gated as 'destructive'
(bash-family commands, rm, etc) would silently appear unblocked across all
turns in multi-turn mode, giving a false 'clean' permission picture to any
claw consuming TurnResult.permission_denials.

Fix: compute denied_tools once at loop start via _infer_permission_denials,
then pass the same denials to every submit_message call (both timeout and
legacy unbounded paths). This mirrors the existing bootstrap_session pattern.

Acceptance: run_turn_loop('run bash ls').permission_denials now matches
what bootstrap_session returns — both infer the same denials from the
routed matches. Multi-turn security posture is symmetric.

Tests (tests/test_run_turn_loop_permissions.py, 2 tests):
- test_turn_loop_surfaces_permission_denials_like_bootstrap: Symmetry
  check confirming both paths infer identical denials for destructive tools
- test_turn_loop_with_continuation_preserves_denials: Denials inferred at
  loop start are passed consistently to all turns; captured via mock and
  verified non-empty

Full suite: 82/82 passing, zero regression.

YeonGyu-Kim faab8a75ba fix: #165 — load-session CLI now parity-matches list/delete (--directory, --output-format, typed JSON errors)
The #160 session-lifecycle CLI triplet was asymmetric: list-sessions and
delete-session accepted --directory + --output-format and emitted typed
JSON error envelopes, but load-session had neither flag and dumped a raw
Python traceback (including the SessionNotFoundError class name) on a
missing session.

Three concrete impacts this fix closes:
1. Alternate session-store locations (e.g. /tmp/claw-run-XXX/.port_sessions)
   were unreachable via load-session; claws had to chdir or monkeypatch
   DEFAULT_SESSION_DIR to work around it.
2. Not-found emitted a multi-line Python stack, not a parseable envelope.
   Claws deciding retry/escalate/give-up had only exit code 1 to work with.
3. The traceback leaked 'src.session_store.SessionNotFoundError' verbatim,
   coupling version-pinned claws to our internal exception class name.

Now all three triplet commands accept the same flag pair and emit the
same JSON error shape:

Success (json mode):
  {"session_id": "alpha", "loaded": true, "messages_count": 3,
   "input_tokens": 42, "output_tokens": 99}

Not-found:
  {"session_id": "missing", "loaded": false,
   "error": {"kind": "session_not_found",
               "message": "session 'missing' not found in /path",
               "directory": "/path", "retryable": false}}

Corrupted file:
  {"session_id": "broken", "loaded": false,
   "error": {"kind": "session_load_failed",
               "message": "...", "directory": "/path",
               "retryable": true}}

Exit code contract:
- 0 on successful load
- 1 on not-found (preserves existing $?)
- 1 on OSError/JSONDecodeError (distinct 'kind' in JSON)

Backward compat: legacy 'claw load-session ID' text output unchanged
byte-for-byte. Only new behaviour is the flags and structured error path.

Tests (tests/test_load_session_cli.py, 13 tests):
- TestDirectoryFlagParity (2): --directory works + fallback to CWD/.port_sessions
- TestOutputFormatFlagParity (2): json schema + text-mode backward compat
- TestNotFoundTypedError (2): JSON envelope on not-found; no traceback in
  either mode; no internal class name leak
- TestLoadFailedDistinctFromNotFound (1): corrupted file = session_load_failed
  with retryable=true, distinct from session_not_found
- TestTripletParityConsistency (6): parametrised over [list, delete, load] *
  [--directory, --output-format] — explicit parity guard for future regressions

Full suite: 80/80 passing, zero regression.

YeonGyu-Kim c2f78215f6 fix: #163 — remove [turn N] suffix pollution from run_turn_loop; file #164 timeout-cancellation followup
#163: run_turn_loop no longer injects f'{prompt} [turn N]' into follow-up
prompts. The suffix was never defined or interpreted anywhere — not by the
engine, not by the system prompt, not by any LLM. It looked like a real
user-typed annotation in the transcript and made replay/analysis fragile.

New behaviour:
- turn 0 submits the original prompt (unchanged)
- turn > 0 submits caller-supplied continuation_prompt if provided, else
  the loop stops cleanly — no fabricated user turn
- added continuation_prompt: str | None = None parameter to run_turn_loop
- added --continuation-prompt CLI flag for claws scripting multi-turn loops
- zero '[turn' strings ever appear in mutable_messages or stdout now

Behaviour change for existing callers:
- Before: run_turn_loop(prompt, max_turns=3) submitted 3 turns
  ('prompt', 'prompt [turn 2]', 'prompt [turn 3]')
- After:  run_turn_loop(prompt, max_turns=3) submits 1 turn ('prompt')
- To preserve old multi-turn behaviour, pass continuation_prompt='Continue.'
  or any structured follow-up text

One existing timeout test (test_budget_is_cumulative_across_turns) updated
to pass continuation_prompt so the cumulative-budget contract is actually
exercised across turns instead of trivially satisfied by a one-turn loop.

#164 filed: addresses reviewer feedback on #161. The wall-clock timeout
bounds the caller-facing wait, but the underlying submit_message worker
thread keeps running and can mutate engine state after the timeout
TurnResult is returned. A cooperative cancel_event pattern is sketched in
the pinpoint; real asyncio.Task.cancel() support will come once provider
IO is async-native (larger refactor).

Tests (tests/test_run_turn_loop_continuation.py, 8 tests):
- TestNoTurnSuffixInjection (2): zero '[turn' strings in any submitted
  prompt, both default and explicit-continuation paths
- TestContinuationDefaultStopsAfterTurnZero (2): default loops run exactly
  one turn; engine.submit_message called exactly once despite max_turns=10
- TestExplicitContinuationBehaviour (2): turn 0 = original, turn N = continuation
  verbatim; max_turns still respected
- TestCLIContinuationFlag (2): CLI default emits only '## Turn 1';
  --continuation-prompt wires through to multi-turn behaviour

Full suite: 67/67 passing.

YeonGyu-Kim 5cc146df7b fix: #162 — budget-overflow no longer corrupts session state in submit_message
Previously, QueryEnginePort.submit_message() checked the token budget AFTER
appending the prompt to mutable_messages, transcript_store, and permission_denials,
and AFTER calling compact_messages_if_needed(). On overflow it set
stop_reason='max_budget_reached' but the overflow turn was already committed.
Any caller that persisted the session afterwards wrote the rejected prompt to
disk — the session was silently poisoned even though the TurnResult said the
turn never completed.

Fix:
- Restructure submit_message so the budget check early-returns BEFORE any
  mutation of mutable_messages, transcript_store, permission_denials, or
  total_usage.
- The returned TurnResult.usage reflects pre-call state (overflow never
  advanced the usage counter).
- Normal (in-budget) path unchanged: mutation happens exactly once, at the
  end, only on 'completed' results.

This closes the atomicity gap: submit_message is now either 'turn committed'
(stop_reason='completed') or 'turn rejected, state untouched'
(stop_reason in {'max_budget_reached', 'max_turns_reached'}). Callers can
safely retry with a fresh budget or a smaller prompt without worrying about
phantom committed turns from prior rejections.

Tests (tests/test_submit_message_budget.py, 10 tests):
- TestBudgetOverflowDoesNotMutate (5): mutable_messages / transcript /
  permission_denials / total_usage / TurnResult.usage all pre-mutation after overflow
- TestOverflowPersistence (2): first-turn overflow persists empty session;
  successful-turn-then-overflow persists only the successful turn
- TestEngineUsableAfterOverflow (2): subsequent in-budget call still works
  with no residue; repeated overflows don't accumulate hidden state
- TestNormalPathStillCommits (1): regression guard — non-overflow path still
  commits mutable_messages/transcript/usage as expected

Full suite: 59/59 passing, zero regression.

Blocker: none. Closes ROADMAP #162.

YeonGyu-Kim 9c4b72749d fix: #161 — wall-clock timeout for run_turn_loop; stalled turns now abort with stop_reason='timeout'
Previously, run_turn_loop was bounded only by max_turns (turn count). If
engine.submit_message stalled — slow provider, hung network, infinite
stream — the loop blocked indefinitely with no cancellation path. Claws
calling run_turn_loop in CI or orchestration had no reliable way to
enforce a deadline; the loop would hang until OS kill or human intervention.

Fix:
- Add timeout_seconds parameter to run_turn_loop (default None = legacy unbounded).
- When set, each submit_message call runs inside a ThreadPoolExecutor and is
  bounded by the remaining wall-clock budget (total across all turns, not per-turn).
- On timeout, synthesize a TurnResult with stop_reason='timeout' carrying the
  turn's prompt and routed matches so transcripts preserve orchestration context.
- Exhausted/negative budget short-circuits before calling submit_message.
- Legacy path (timeout_seconds=None) bypasses the executor entirely — zero
  overhead for callers that don't opt in.

CLI:
- Added --timeout-seconds flag to 'turn-loop' command.
- Exit code 2 when the loop terminated on timeout (vs 0 for completed),
  so shell scripts can distinguish 'done' from 'budget exhausted'.

Tests (tests/test_run_turn_loop_timeout.py, 6 tests):
- Legacy unbounded path unchanged (timeout_seconds=None never emits 'timeout')
- Hung submit_message aborted within budget (0.3s budget, 5s mock hang → exit <1.5s)
- Budget is cumulative across turns (0.6s budget, 0.4s per turn, not per-turn)
- timeout_seconds=0 short-circuits first turn without calling submit_message
- Negative timeout treated as exhausted (guard against caller bugs)
- Timeout TurnResult carries correct prompt, matches, UsageSummary shape

Blocker: none. Closes ROADMAP #161.

YeonGyu-Kim 966935ffa8 feat(#160): wire claw list-sessions and delete-session CLI commands
Closes the last #160 gap: claws can now manage session lifecycle entirely
through the CLI without filesystem hacks.

New commands:
- claw list-sessions [--directory DIR] [--output-format text|json]
  Enumerates stored session IDs. JSON mode emits {sessions, count}.
  Missing/empty directories return empty list (exit 0), not an error.

- claw delete-session SESSION_ID [--directory DIR] [--output-format text|json]
  Idempotent: not-found is exit 0 with status='not_found' (no raise).
  Partial-failure: exit 1 with typed JSON error envelope:
    {session_id, deleted: false, error: {kind, message, retryable}}
  The 'session_delete_failed' kind is retryable=true so orchestrators
  know to retry vs escalate.

Public API surface extended in src/__init__.py:
- list_sessions, session_exists, delete_session
- SessionNotFoundError, SessionDeleteError

Tests added (tests/test_porting_workspace.py):
- test_list_sessions_cli_runs: text + json modes against tempdir
- test_delete_session_cli_idempotent: first call deleted=true,
  second call deleted=false (exit 0, status=not_found)
- test_delete_session_cli_partial_failure_exit_1: permission error
  surfaces as exit 1 + typed JSON error with retryable=true

All 43 tests pass. The session storage abstraction chapter is closed:
- storage layer decoupled from claw code (#160 initial impl)
- delete contract hardened + caller-audited (#160 hardening pass)
- CLI wired with idempotency preserved at exit-code boundary (this commit)

YeonGyu-Kim 9f9b9187d3 fix(#160): harden delete_session contract — idempotency, race-safety, typed partial-failure
Addresses review feedback on initial #160 implementation:

1. delete_session() contract now explicit:
   - Idempotent: delete(x); delete(x) is safe, second call returns False
   - Race-safe: TOCTOU between exists()/unlink() eliminated via unlink-then-catch
   - Partial-failure typed: permission/IO errors wrapped in SessionDeleteError (OSError subclass)
     so callers can distinguish 'not found' (return False) from 'could not delete' (raise)

2. New SessionDeleteError class for partial-failure surfacing.
   Distinct from SessionNotFoundError (KeyError subclass for missing loads).

3. Caller audit confirmed: no code outside session_store globs .port_sessions
   or imports DEFAULT_SESSION_DIR. Storage layout is fully encapsulated.

4. Added tests/test_session_store.py — 18 tests covering:
   - list_sessions: empty/missing/sorted/non-json filter
   - session_exists: true/false/missing-dir
   - load_session: SessionNotFoundError typing (KeyError subclass, not FileNotFoundError)
   - delete_session idempotency: first/second/never-existed calls
   - delete_session partial-failure: SessionDeleteError wraps OSError
   - delete_session race-safety: concurrent deletion returns False, not raise
   - Full save->list->exists->load->delete roundtrip

All 18 tests pass. Merge-ready: contract documented, caller-audited, race-safe.

- delete_session(session_id, directory=None) -> bool: unlink a session file
- load_session now raises typed SessionNotFoundError (subclass of KeyError) instead of FileNotFoundError
- Claws can now manage session lifecycle without reaching past the module to glob filesystem

Closes ROADMAP #160. Acceptance: claw can call list_sessions(), session_exists(id), delete_session(id) without importing Path or knowing .port_sessions/<id>.json layout.

YeonGyu-Kim ef1cfa1777 file: #157 — structured remediation registry for error hints (Phase 3 of #77)
## Gap

#77 Phase 1 added machine-readable error kind discriminants and #156 extended
them to text-mode output. However, the hint field is still prose derived from
splitting existing error text — not a stable registry-backed remediation
contract.

Downstream claws inspecting the hint field still need to parse human wording
to decide whether to retry, escalate, or terminate.

## Fix Shape

1. Remediation registry: remediation_for(kind, operation) -> Remediation struct
   with action (retry/escalate/terminate/configure), target, and stable message
2. Stable hint outputs per error class (no more prose splitting)
3. Golden fixture tests replacing split_error_hint() string hacks

YeonGyu-Kim f1e4ad7574 feat: #156 — error classification for text-mode output (Phase 2 of #77)
## Problem

#77 Phase 1 added machine-readable error `kind` discriminants to JSON error
payloads. Text-mode (stderr) errors still emit prose-only output with no
structured classification.

Observability tools (log aggregators, CI error parsers) parsing stderr can't
distinguish error classes without regex-scraping the prose.

## Fix

Added `[error-kind: <class>]` prefix line to all text-mode error output.
The prefix appears before the error prose, making it immediately parseable by
line-based log tools without any substring matching.

**Examples:**

## Impact

- Stderr observers (log aggregators, CI systems) can now parse error class
  from the first line without regex or substring scraping
- Same classifier function used for JSON (#77 P1) and text modes
- Text-mode output remains human-readable (error prose unchanged)
- Prefix format follows syslog/structured-logging conventions

## Tests

All 179 rusty-claude-cli tests pass. Verified on 3 different error classes.

Closes ROADMAP #156.

YeonGyu-Kim 14c5ef1808 file: #156 — error classification for text-mode output (Phase 2 of #77)
ROADMAP entry for natural Phase 2 follow-up to #77 Phase 1 (JSON error kind
classification). Text-mode errors currently prose-only with no structured
class; observability tools parsing stderr need the kind token.

Two implementation options:
- Prefix line before error prose: [error-kind: missing_credentials]
- Suffix comment: # error_class=missing_credentials

Scope: ~20 lines. Non-breaking (adds classification, doesn't change error text).

today's batch, identified natural next step for error-classification symmetry.

YeonGyu-Kim 9362900b1b feat: #77 Phase 1 — machine-readable error classification in JSON error payloads
## Problem

All JSON error payloads had the same three-field envelope:
```json
{"type": "error", "error": "<prose with hint baked in>"}
```

Five distinct error classes were indistinguishable at the schema level:
- missing_credentials (no API key)
- missing_worker_state (no state file)
- session_not_found / session_load_failed
- cli_parse (unrecognized args)
- invalid_model_syntax

Downstream claws had to regex-scrape the prose to route failures.

## Fix

1. **Added `classify_error_kind()`** — prefix/keyword classifier that returns a
   snake_case discriminant token for 12 known error classes:
   `missing_credentials`, `missing_manifests`, `missing_worker_state`,
   `session_not_found`, `session_load_failed`, `no_managed_sessions`,
   `cli_parse`, `invalid_model_syntax`, `unsupported_command`,
   `unsupported_resumed_command`, `confirmation_required`, `api_http_error`,
   plus `unknown` fallback.

2. **Added `split_error_hint()`** — splits multi-line error messages into
   (short_reason, optional_hint) so the runbook prose stops being stuffed
   into the `error` field.

3. **Extended JSON envelope** at 4 emit sites:
   - Main error sink (line ~213)
   - Session load failure in resume_session
   - Stub command (unsupported_command)
   - Unknown resumed command (unsupported_resumed_command)

## New JSON shape

```json
{
  "type": "error",
  "error": "short reason (first line)",
  "kind": "missing_credentials",
  "hint": "Hint: export ANTHROPIC_API_KEY..."
}
```

`kind` is always present. `hint` is null when no runbook follows.
`error` now carries only the short reason, not the full multi-line prose.

## Tests

Added 2 new regression tests:
- `classify_error_kind_returns_correct_discriminants` — all 9 known classes + fallback
- `split_error_hint_separates_reason_from_runbook` — with and without hints

All 179 rusty-claude-cli tests pass. Full workspace green.

Closes ROADMAP #77 Phase 1.

YeonGyu-Kim ff45e971aa fix: #80 — session-lookup error messages now show actual workspace-fingerprint directory
## Problem

Two session error messages advertised `.claw/sessions/` as the managed-session
location, but the actual on-disk layout is `.claw/sessions/<workspace_fingerprint>/`
where the fingerprint is a 16-char FNV-1a hash of the CWD path.

Users see error messages like:
```
no managed sessions found in .claw/sessions/
```

But the real directory is:
```
.claw/sessions/8497f4bcf995fc19/
```

The error copy was a direct lie — it made workspace-fingerprint partitioning
invisible and left users confused about whether sessions were lost or just in
a different partition.

## Fix

Updated two error formatters to accept the resolved `sessions_root` path
and extract the actual workspace-fingerprint directory:

1. **format_missing_session_reference**: now shows the actual fingerprint dir
   and explains that it's a workspace-specific partition

2. **format_no_managed_sessions**: now shows the actual fingerprint dir and
   includes a note that sessions from other CWDs are intentionally invisible

Updated all three call sites to pass `&self.sessions_root` to the formatters.

## Examples

**Before:**
```
no managed sessions found in .claw/sessions/
```

**After:**
```
no managed sessions found in .claw/sessions/8497f4bcf995fc19/
Start `claw` to create a session, then rerun with `--resume latest`.
Note: claw partitions sessions per workspace fingerprint; sessions from other CWDs are invisible.
```

```
session not found: nonexistent-id
Hint: managed sessions live in .claw/sessions/8497f4bcf995fc19/ (workspace-specific partition).
Try `latest` for the most recent session or `/session list` in the REPL.
```

## Impact

- Users can now tell from the error message that they're looking in the right
  directory (the one their current CWD maps to)
- The workspace-fingerprint partitioning stops being invisible
- Operators understand why sessions from adjacent CWDs don't appear
- Error copy matches the actual on-disk structure

## Tests

All 466 runtime tests pass. Verified on two real workspaces with actual
workspace-fingerprint directories.

Closes ROADMAP #80.

YeonGyu-Kim 4b53b97e36 docs: #155 — add USAGE.md documentation for /ultraplan, /teleport, /bughunter commands
## Problem

Three interactive slash commands are documented in `claw --help` but have no
corresponding section in USAGE.md:

- `/ultraplan [task]` — Run a deep planning prompt with multi-step reasoning
- `/teleport <symbol-or-path>` — Jump to a file or symbol by searching the workspace
- `/bughunter [scope]` — Inspect the codebase for likely bugs

New users see these commands in the help output but don't know:
- What each command does
- How to use it
- When to use it vs. other commands
- What kind of results to expect

## Fix

Added new section "Advanced slash commands (Interactive REPL only)" to USAGE.md
with documentation for all three commands:

1. **`/ultraplan`** — multi-step reasoning for complex tasks
   - Example: `/ultraplan refactor the auth module to use async/await`
   - Output: structured plan with numbered steps and reasoning

2. **`/teleport`** — navigate to a file or symbol
   - Example: `/teleport UserService`, `/teleport src/auth.rs`
   - Output: file content with the requested symbol highlighted

3. **`/bughunter`** — scan for likely bugs
   - Example: `/bughunter src/handlers`, `/bughunter` (all)
   - Output: list of suspicious patterns with explanations

## Impact

Users can now discover these commands and understand when to use them without
having to guess or search external sources. Bridges the gap between `--help`
output and full documentation.

Also filed ROADMAP #155 documenting the gap.

Closes ROADMAP #155.

YeonGyu-Kim 3cfe6e2b14 feat: #154 — hint provider prefix and env var when model name looks like different provider
## Problem

When a user types `claw --model gpt-4` or `--model qwen-plus`, they get:
```
error: invalid model syntax: 'gpt-4'. Expected provider/model (e.g., anthropic/claude-opus-4-6) or known alias
```

USAGE.md documents that "The error message now includes a hint that names the detected env var" — but this hint does not actually exist. The user has to re-read USAGE.md or guess the correct prefix.

## Fix

Enhance `validate_model_syntax` to detect when a model name looks like it belongs to a different provider:

1. **OpenAI models** (starts with `gpt-` or `gpt_`):
   ```
   Did you mean `openai/gpt-4`? (Requires OPENAI_API_KEY env var)
   ```

2. **Qwen/DashScope models** (starts with `qwen`):
   ```
   Did you mean `qwen/qwen-plus`? (Requires DASHSCOPE_API_KEY env var)
   ```

3. **Grok/xAI models** (starts with `grok`):
   ```
   Did you mean `xai/grok-3`? (Requires XAI_API_KEY env var)
   ```

Unrelated invalid models (e.g., `asdfgh`) do not get a spurious hint.

## Verification

- `claw --model gpt-4` → hints `openai/gpt-4` + `OPENAI_API_KEY`
- `claw --model qwen-plus` → hints `qwen/qwen-plus` + `DASHSCOPE_API_KEY`
- `claw --model grok-3` → hints `xai/grok-3` + `XAI_API_KEY`
- `claw --model asdfgh` → generic error (no hint)

## Tests

Added 3 new assertions in `parses_multiple_diagnostic_subcommands`:
- GPT model error hints openai/ prefix and OPENAI_API_KEY
- Qwen model error hints qwen/ prefix and DASHSCOPE_API_KEY
- Unrelated models don't get a spurious hint

All 177 rusty-claude-cli tests pass.

Closes ROADMAP #154.

YeonGyu-Kim 71f5f83adb feat: #153 — add post-build binary location and verification guide to README
## Problem

Users frequently ask after building:
- "Where is the claw binary?"
- "Did the build actually work?"
- "Why can't I run \`claw\` from anywhere?"

This happens because \`cargo build\` puts the binary in \`rust/target/debug/claw\`
(or \`rust/target/release/claw\`), and new users don't know:
1. Where to find it
2. How to test it
3. How to add it to PATH (optional but common follow-up)

## Fix

Added new section "Post-build: locate the binary and verify" to README covering:

1. **Binary location table:** debug vs. release, macOS/Linux vs. Windows paths
2. **Verification commands:** Test the binary with \`--help\` and \`doctor\`
3. **Three ways to add to PATH:**
   - Symlink (macOS/Linux): \`ln -s ... /usr/local/bin/claw\`
   - cargo install: \`cargo install --path . --force\`
   - Shell profile update: add rust/target/debug to \$PATH
4. **Troubleshooting:** Common errors ("command not found", "permission denied",
   debug vs. release build speed)

## Impact

New users can now:
- Find the binary immediately after build
- Run it and verify with \`claw doctor\`
- Know their options for system-wide access

Also filed ROADMAP #153 documenting the gap.

Closes ROADMAP #153.

YeonGyu-Kim 79352a2d20 feat: #152 — hint --output-format json when user types --json on diagnostic verbs
## Problem

Users commonly type `claw doctor --json`, `claw status --json`, or
`claw system-prompt --json` expecting JSON output. These fail with
`unrecognized argument \`--json\` for subcommand` with no hint that
`--output-format json` is the correct flag.

## Discovery

Filed as #152 during 21:17 dogfood nudge. The #127 worktree contained
a more comprehensive patch but conflicted with #141 (unified --help).
On re-investigation of main, Bugs 1 and 3 from #127 are already closed
(positional arg rejection works, no double "error:" prefix). Only
Bug 2 (the `--json` hint) remained.

## Fix

Two call sites add the hint:

1. `parse_single_word_command_alias`'s diagnostic-verb suffix path:
   when rest[1] == "--json", append "Did you mean \`--output-format json\`?"

2. `parse_system_prompt_options` unknown-option path: same hint when
   the option is exactly `--json`.

## Verification

Before:
  $ claw doctor --json
  error: unrecognized argument `--json` for subcommand `doctor`
  Run `claw --help` for usage.

After:
  $ claw doctor --json
  error: unrecognized argument `--json` for subcommand `doctor`
  Did you mean `--output-format json`?
  Run `claw --help` for usage.

Covers: `doctor --json`, `status --json`, `sandbox --json`,
`system-prompt --json`, and any other diagnostic verb that routes
through `parse_single_word_command_alias`.

Other unrecognized args (`claw doctor garbage`) correctly don't
trigger the hint.

## Tests

- 2 new assertions in `parses_multiple_diagnostic_subcommands`:
  - `claw doctor --json` produces hint
  - `claw doctor garbage` does NOT produce hint
- 177 rusty-claude-cli tests pass
- Workspace tests green

Closes ROADMAP #152.

YeonGyu-Kim 7bc66e86e8 feat: #151 — canonicalize workspace path in SessionStore::from_cwd/data_dir
## Problem

`workspace_fingerprint(path)` hashes the raw path string without
canonicalization. Two equivalent paths (e.g. `/tmp/foo` vs
`/private/tmp/foo` on macOS) produce different fingerprints and
therefore different session stores. #150 fixed the test-side symptom;
this fixes the underlying product contract.

## Discovery path

#150 fix (canonicalize in test) was a workaround. Q's ack on #150
surfaced the deeper gap: the function itself is still fragile for
any caller passing a non-canonical path:

1. Embedded callers with a raw `--data-dir` path
2. Programmatic `SessionStore::from_cwd(user_path)` calls
3. NixOS store paths, Docker bind mounts, case-insensitive normalization

The REPL's default flow happens to work because `env::current_dir()`
returns canonical paths on macOS. But any caller passing a raw path
risks silent session-store divergence.

## Fix

Canonicalize inside `SessionStore::from_cwd()` and `from_data_dir()`
before computing the fingerprint. Kept `workspace_fingerprint()` itself
as a pure function for determinism — canonicalization is the entry
point's responsibility.

```rust
let canonical_cwd = fs::canonicalize(cwd).unwrap_or_else(|_| cwd.to_path_buf());
let sessions_root = canonical_cwd.join(".claw").join("sessions").join(workspace_fingerprint(&canonical_cwd));
```

Falls back to the raw path if canonicalize fails (directory doesn't
exist yet).

## Test-side updates

Three legacy-session tests expected the non-canonical base path to
match the store's workspace_root. Updated them to canonicalize
`base` after creation — same defensive pattern as #150, now
explicit across all three tests.

## Regression test

Added `session_store_from_cwd_canonicalizes_equivalent_paths` that
creates two stores from equivalent paths (raw vs canonical) and
asserts they resolve to the same sessions_dir.

## Verification

- `cargo test -p runtime session_store_` — 9/9 pass
- `cargo test --workspace` — all green, no FAILED markers
- No behavior change for existing users (REPL default flow already
  used canonical paths)

## Backward compatibility

Users on macOS who always went through `env::current_dir()`:
no hash change, sessions resume identically.

Users who ever called with a non-canonical path: hash would change,
but those sessions were already broken (couldn't be resumed from a
canonical-path cwd). Net improvement.

Closes ROADMAP #151.

YeonGyu-Kim eaa077bf91 fix: #150 — eliminate symlink canonicalization flake in resume_latest test + file #246 (reminder outcome ambiguity)
## #150 Fix: resume_latest test flake

**Problem:** `resume_latest_restores_the_most_recent_managed_session` intermittently
fails when run in the workspace suite or multiple times in sequence, but passes in
isolation.

**Root cause:** `workspace_fingerprint(path)` hashes the path string without
canonicalization. On macOS, `/tmp` is a symlink to `/private/tmp`. The test
creates a temp dir via `std::env::temp_dir().join(...)` which returns
`/var/folders/...` (non-canonical). When the subprocess spawns,
`env::current_dir()` returns the canonical path `/private/var/folders/...`.
The two fingerprints differ, so the subprocess looks in
`.claw/sessions/<hash1>` while files are in `.claw/sessions/<hash2>`.
Session discovery fails.

**Fix:** Call `fs::canonicalize(&project_dir)` after creating the directory
to ensure test and subprocess use identical path representations.

**Verification:** 5 consecutive runs of the full test suite — all pass.
Previously: 5/5 failed when run in sequence.

## #246 Filing: Reminder cron outcome ambiguity (control-loop blocker)

The `clawcode-dogfood-cycle-reminder` cron times out repeatedly with no
structured feedback on whether the nudge was delivered, skipped, or died in-flight.

**Phase 1 outcome schema** — add explicit field to cron result:
- `delivered` — nudge posted to Discord
- `timed_out_before_send` — died before posting
- `timed_out_after_send` — posted but cleanup timed out
- `skipped_due_to_active_cycle` — previous cycle active
- `aborted_gateway_draining` — daemon shutdown

dogfood cycle observability.

YeonGyu-Kim bc259ec6f9 fix: #149 — eliminate parallel-test flake in runtime::config tests
## Problem

`runtime::config::tests::validates_unknown_top_level_keys_with_line_and_field_name`
intermittently fails during `cargo test --workspace` (witnessed during
#147 and #148 workspace runs) but passes deterministically in isolation.

Example failure from workspace run:
  test result: FAILED. 464 passed; 1 failed

## Root cause

`runtime/src/config.rs::tests::temp_dir()` used nanosecond timestamp
alone for namespace isolation:

  std::env::temp_dir().join(format!("runtime-config-{nanos}"))

Under parallel test execution on fast machines with coarse clock
resolution, two tests start within the same nanosecond bucket and
collide on the same path. One test's `fs::remove_dir_all(root)` then
races another's in-flight `fs::create_dir_all()`.

Other crates already solved this pattern:
- plugins::tests::temp_dir(label) — label-parameterized
- runtime::git_context::tests::temp_dir(label) — label-parameterized

runtime/src/config.rs was missed.

## Fix

Added process id + monotonically-incrementing atomic counter to the
namespace, making every callsite provably unique regardless of clock
resolution or scheduling:

  static COUNTER: AtomicU64 = AtomicU64::new(0);
  let pid = std::process::id();
  let seq = COUNTER.fetch_add(1, Ordering::Relaxed);
  std::env::temp_dir().join(format!("runtime-config-{pid}-{nanos}-{seq}"))

Chose counter+pid over the label-parameterized pattern to avoid
touching all 20 callsites in the same commit (mechanical noise with
no added safety — counter alone is sufficient).

## Verification

Before: one failure per workspace run (config test flake).
After: 5 consecutive `cargo test --workspace` runs — zero config
test failures. Only pre-existing `resume_latest` flake remains
(orthogonal, unrelated to this change).

  for i in 1 2 3 4 5; do cargo test --workspace; done
  # All 5 runs: config tests green. Only resume_latest flake appears.

  cargo test -p runtime
  # 465 passed; 0 failed

YeonGyu-Kim f84c7c4ed5 feat: #148 + #128 closure — model provenance in claw status JSON/text
## Scope

Two deltas in one commit:

### #128 closure (docs)

Re-verified on main HEAD `4cb8fa0`: malformed `--model` strings already
rejected at parse time (`validate_model_syntax` in parse_args). All
historical repro cases now produce specific errors:

  claw --model ''                       → error: model string cannot be empty
  claw --model 'bad model'              → error: invalid model syntax: 'bad model' contains spaces
  claw --model 'sonet'                  → error: invalid model syntax: 'sonet'. Expected provider/model or known alias
  claw --model '@invalid'               → error: invalid model syntax: '@invalid'. Expected provider/model ...
  claw --model 'totally-not-real-xyz'   → error: invalid model syntax: ...
  claw --model sonnet                   → ok, resolves to claude-sonnet-4-6
  claw --model anthropic/claude-opus-4-6 → ok, passes through

Marked #128 CLOSED in ROADMAP with repro block. Residual provenance gap
split off as #148.

### #148 implementation

**Problem.** After #128 closure, `claw status --output-format json`
still surfaces only the resolved model string. No way for a claw to
distinguish whether `claude-sonnet-4-6` came from `--model sonnet`
(alias resolution) vs `--model claude-sonnet-4-6` (pass-through) vs
`ANTHROPIC_MODEL` env vs `.claw.json` config vs compiled-in default.

Debug forensics had to re-read argv instead of reading a structured
field. Clawhip orchestrators sending `--model` couldn't confirm the
flag was honored vs falling back to default.

**Fix.** Added two fields to status JSON envelope:
- `model_source`: "flag" | "env" | "config" | "default"
- `model_raw`: user's input before alias resolution (null on default)

Text mode appends a `Model source` line under `Model`, showing the
source and raw input (e.g. `Model source     flag (raw: sonnet)`).

**Resolution order** (mirrors resolve_repl_model but with source
attribution):
1. If `--model` / `--model=` flag supplied → source: flag, raw: flag value
2. Else if ANTHROPIC_MODEL set → source: env, raw: env value
3. Else if `.claw.json` model key set → source: config, raw: config value
4. Else → source: default, raw: null

## Changes

### rust/crates/rusty-claude-cli/src/main.rs

- Added `ModelSource` enum (Flag/Env/Config/Default) with `as_str()`.
- Added `ModelProvenance` struct (resolved, raw, source) with
  three constructors: `default_fallback()`, `from_flag(raw)`, and
  `from_env_or_config_or_default(cli_model)`.
- Added `model_flag_raw: Option<String>` field to `CliAction::Status`.
- Parse loop captures raw input in `--model` and `--model=` arms.
- Extended `parse_single_word_command_alias` to thread
  `model_flag_raw: Option<&str>` through.
- Extended `print_status_snapshot` signature to accept
  `model_flag_raw: Option<&str>`. Resolves provenance at dispatch time
  (flag provenance from arg; else probe env/config/default).
- Extended `status_json_value` signature with
  `provenance: Option<&ModelProvenance>`. On Some, adds `model_source`
  and `model_raw` fields; on None (legacy resume paths), omits them
  for backward compat.
- Extended `format_status_report` signature with optional provenance.
  On Some, renders `Model source` line after `Model`.
- Updated all existing callers (REPL /status, resume /status, tests)
  to pass None (legacy paths don't carry flag provenance).
- Added 2 regression assertions in parse_args test covering both
  `--model sonnet` and `--model=...` forms.

### ROADMAP.md

- Marked #128 CLOSED with re-verification block.
- Filed #148 documenting the provenance gap split, fix shape, and
  acceptance criteria.

YeonGyu-Kim 4cb8fa059a feat: #147 — reject empty / whitespace-only prompts at CLI fallthrough
## Problem

The `"prompt"` subcommand arm enforced `if prompt.trim().is_empty()`
and returned a specific error. The fallthrough `other` arm in the same
match block — which routes any unrecognized first positional arg to
`CliAction::Prompt` — had no such guard. Result:

$ claw ""
error: missing Anthropic credentials; export ANTHROPIC_AUTH_TOKEN ...

$ claw "   "
error: missing Anthropic credentials; ...

$ claw "" ""
error: missing Anthropic credentials; ...

$ claw --output-format json ""
{"error":"missing Anthropic credentials; ...","type":"error"}

An empty prompt should never reach the credentials check. Worse: with
valid credentials, the literal empty string gets sent to Claude as a
user prompt, either burning tokens for nothing or triggering a model-
side refusal. Same prompt-misdelivery family as #145.

## Root cause

In `parse_subcommand()`, the final `other =>` arm in the top-level
match only guards against typos (#108 guard via `looks_like_subcommand_typo`)
and then unconditionally builds `CliAction::Prompt { prompt: rest.join(" ") }`.
An empty/whitespace-only join passes through.

## Changes

### rust/crates/rusty-claude-cli/src/main.rs

Added the same `if joined.trim().is_empty()` guard already used in the
`"prompt"` arm to the fallthrough path. Error message distinguishes it
from the `prompt` subcommand path:

  empty prompt: provide a subcommand (run `claw --help`) or a
  non-empty prompt string

Runs AFTER the typo guard (so `claw sttaus` still suggests `status`)
and BEFORE CliAction::Prompt construction (so no network call ever
happens for empty inputs).

### Regression tests

Added 4 assertions in the existing parse_args test:
- parse_args([""]) → Err("empty prompt: ...")
- parse_args(["   "]) → Err("empty prompt: ...")
- parse_args(["", ""]) → Err("empty prompt: ...")
- parse_args(["sttaus"]) → Err("unknown subcommand: ...") [verifies #108 typo guard still takes precedence]

### ROADMAP.md

Added Pinpoint #147 documenting the gap, verification, root cause,
fix shape, and acceptance. Joins the prompt-misdelivery cluster
alongside #145.

## Live verification

$ claw ""
error: empty prompt: provide a subcommand (run `claw --help`) or a non-empty prompt string

$ claw "   "
error: empty prompt: provide a subcommand (run `claw --help`) or a non-empty prompt string

error: unknown subcommand: hello.
  Did you mean     help

$ claw "real prompt here"   # unchanged: real prompts still reach API

YeonGyu-Kim f877acacbf feat: #146 — wire claw config and claw diff as standalone subcommands
## Problem

`claw config` and `claw diff` are pure-local read-only introspection
commands (config merges .claw.json + .claw/settings.json from disk; diff
shells out to `git diff --cached` + `git diff`). Neither needs a session
context, yet both rejected direct CLI invocation:

$ claw config
error: `claw config` is a slash command. Use `claw --resume SESSION.jsonl /config` ...

$ claw diff
error: `claw diff` is a slash command. ...

This forced clawing operators to spin up a full session just to inspect
static disk state, and broke natural pipelines like
`claw config --output-format json | jq`.

## Root cause

Sibling of #145: `SlashCommand::Config { section }` and
`SlashCommand::Diff` had working renderers (`render_config_report`,
`render_config_json`, `render_diff_report`, `render_diff_json_for`)
exposed for resume sessions, but the top-level CLI parser in
`parse_subcommand()` had no arms for them. Zero-arg `config`/`diff`
hit `parse_single_word_command_alias`'s fallback to
`bare_slash_command_guidance`, producing the misleading guidance.

## Changes

### rust/crates/rusty-claude-cli/src/main.rs

- Added `CliAction::Config { section, output_format }` and
  `CliAction::Diff { output_format }` variants.
- Added `"config"` / `"diff"` arms to the top-level parser in
  `parse_subcommand()`. `config` accepts an optional section name
  (env|hooks|model|plugins) matching SlashCommand::Config semantics.
  `diff` takes no positional args. Both reject extra trailing args
  with a clear error.
- Added `"config" | "diff" => None` to
  `parse_single_word_command_alias` so bare invocations fall through
  to the new parser arms instead of the slash-guidance error.
- Added dispatch in run() that calls existing renderers: text mode uses
  `render_config_report` / `render_diff_report`; JSON mode uses
  `render_config_json` / `render_diff_json_for` with
  `serde_json::to_string_pretty`.
- Added 5 regression assertions in parse_args test covering:
  parse_args(["config"]), parse_args(["config", "env"]),
  parse_args(["config", "--output-format", "json"]),
  parse_args(["diff"]), parse_args(["diff", "--output-format", "json"]).

### ROADMAP.md

Added Pinpoint #146 documenting the gap, verification, root cause,
fix shape, and acceptance. Explicitly notes which other slash commands
(`hooks`, `usage`, `context`, etc.) are NOT candidates because they
are session-state-modifying.

YeonGyu-Kim 7d63699f9f feat: #145 — wire claw plugins subcommand to CLI parser (prompt misdelivery fix)
## Problem

`claw plugins` (and `claw plugins list`, `claw plugins --help`,
`claw plugins info <name>`, etc.) fell through the top-level subcommand
match and got routed into the prompt-execution path. Result: a purely
local introspection command triggered an Anthropic API call and surfaced
`missing Anthropic credentials` to the user. With valid credentials, it
would actually send the literal string "plugins" as a user prompt to
Claude, burning tokens for a local query.

$ claw plugins
error: missing Anthropic credentials; export ANTHROPIC_AUTH_TOKEN or ANTHROPIC_API_KEY before calling the Anthropic API

$ ANTHROPIC_API_KEY=dummy claw plugins
⠋ 🦀 Thinking...
✘  Request failed
error: api returned 401 Unauthorized

Meanwhile siblings (`agents`, `mcp`, `skills`) all worked correctly:

$ claw agents
No agents found.
$ claw mcp
MCP
  Working directory ...
  Configured servers 0

## Root cause

`CliAction::Plugins` exists, has a working dispatcher
(`LiveCli::print_plugins`), and is produced inside the REPL via
`SlashCommand::Plugins`. But the top-level CLI parser in
`parse_subcommand()` had arms for `agents`, `mcp`, `skills`, `status`,
`doctor`, `init`, `export`, `prompt`, etc., and **no arm for
`plugins`**. The dispatch never ran from the CLI entry point.

## Changes

### rust/crates/rusty-claude-cli/src/main.rs

Added a `"plugins"` arm to the top-level match in `parse_subcommand()`
that produces `CliAction::Plugins { action, target, output_format }`,
following the same positional convention as `mcp` (`action` = first
positional, `target` = second). Rejects >2 positional args with a clear
error.

Added four regression assertions in the existing `parse_args` test:
- `plugins` alone → `CliAction::Plugins { action: None, target: None }`
- `plugins list` → action: Some("list"), target: None
- `plugins enable <name>` → action: Some("enable"), target: Some(...)
- `plugins --output-format json` → action: None, output_format: Json

### ROADMAP.md

Added Pinpoint #145 documenting the gap, verification, root cause,
fix shape, and acceptance.

## Live verification

$ claw plugins   # no credentials set

YeonGyu-Kim faeaa1d30c feat: #144 phase 1 + ROADMAP filing — claw mcp degrades gracefully on malformed config
Filing + Phase 1 fix in one commit (sibling of #143).

## Context

With #143 Phase 1 landed (`claw status` degrades), `claw mcp` was the
remaining diagnostic surface that hard-failed on a malformed `.claw.json`.
Same input, same parse error, same partial-success violation. Fresh
dogfood at 18:59 KST caught it on main HEAD `e2a43fc`.

## Changes

### ROADMAP.md
Added Pinpoint #144 documenting the gap and acceptance criteria. Joins
the partial-success / Principle #5 cluster with #143.

### rust/crates/commands/src/lib.rs
`render_mcp_report_for()` + `render_mcp_report_json_for()` now catch the
ConfigError at loader.load() instead of propagating:

- **Text mode** prepends a "Config load error" block (same shape as
  #143's status output) before the MCP listing. The listing still renders
  with empty servers so the output structure is preserved.
- **JSON mode** adds top-level `status: "ok" | "degraded"` +
  `config_load_error: string | null` fields alongside existing fields
  (`kind`, `action`, `working_directory`, `configured_servers`,
  `servers[]`). On clean runs, `status: "ok"` and
  `config_load_error: null`. On parse failure, `status: "degraded"`,
  `config_load_error: "..."`, `servers: []`, exit 0.
- Both list and show actions get the same treatment.

### Regression test
`commands::tests::mcp_degrades_gracefully_on_malformed_mcp_config_144`:
- Injects the same malformed .claw.json as #143 (one valid + one broken
  mcpServers entry).
- Asserts mcp list returns Ok (not Err).
- Asserts top-level status: "degraded" and config_load_error names the
  malformed field path.
- Asserts show action also degrades.
- Asserts clean path returns status: "ok" with config_load_error null.

## Live verification

$ claw mcp --output-format json
{
  "action": "list",
  "kind": "mcp",
  "status": "degraded",
  "config_load_error": ".../.claw.json: mcpServers.missing-command: missing string field command",
  "working_directory": "/Users/yeongyu/clawd",
  "configured_servers": 0,
  "servers": []
}
Exit 0.

## Contract alignment after this commit

All three diagnostic surfaces match now:
- `doctor` — degraded envelope with typed check entries 
- `status` — degraded envelope with config_load_error  (#143)
- `mcp` — degraded envelope with config_load_error  (this commit)

Phase 2 (typed-error object joining taxonomy §4.44) tracked separately
across all three surfaces.

Full workspace test green except pre-existing resume_latest flake (unrelated).

Closes ROADMAP #144 phase 1.

YeonGyu-Kim e2a43fcd49 feat: #143 phase 1 — claw status degrades gracefully on malformed config
Previously `claw status` hard-failed on any config parse error, emitting
a bare error string and exiting 1. This took down the entire health
surface for a single malformed MCP entry, even though workspace, git,
model, permission, and sandbox state could all be reported independently.

`claw doctor` already degraded gracefully on the exact same input.
This commit matches `claw status` to that contract.

Changes:
- Add `StatusContext::config_load_error: Option<String>` to capture parse
  errors without aborting.
- Rewrite `status_context()` to match on `ConfigLoader::load()`: on Err,
  fall back to default `SandboxConfig` for sandbox resolution and record
  the parse error, then continue populating workspace/git/memory fields.
- JSON output gains top-level `status: "ok" | "degraded"` marker and a
  `config_load_error` string (null on clean runs). All other existing
  fields preserved for backward compat.
- Text output prepends a "Config load error" block with Details + Hint
  when config failed to parse, then a "Status (degraded)" header on the
  main block. Clean runs show the usual "Status" header.
- Doctor path updated to pass the config load error through StatusContext.

Regression test `status_degrades_gracefully_on_malformed_mcp_config_143`:
- Injects a .claw.json with one valid + one malformed mcpServers entry
- Asserts status_context() returns Ok (not Err)
- Asserts config_load_error names the malformed field path
- Asserts workspace/sandbox fields still populated in JSON
- Asserts top-level status is 'degraded'
- Asserts clean config path still returns status: 'ok'

Verified live on /Users/yeongyu/clawd (contains deliberately broken MCP entries):
  $ claw status --output-format json
  { "status": "degraded",
    "config_load_error": ".../mcpServers.missing-command: missing string field command",
    "model": "claude-opus-4-6",
    "workspace": {...},
    "sandbox": {...},
    ... }

Phase 2 (typed error object joining #4.44 taxonomy) tracked separately.

Full workspace test green except pre-existing resume_latest flake (unrelated).

YeonGyu-Kim e73b6a2364 docs: USAGE.md sections for claw init (#142) and claw state (#139)
Add two missing sections documenting the recently-fixed commands:

- **Initialize a repository**: Shows both text and JSON output modes for
  `claw init`. Explains that structured JSON fields (created[], updated[],
  skipped[], artifacts[]) allow claws to detect per-artifact state without
  substring-matching prose. Documents idempotency.

- **Inspect worker state**: Documents `claw state` and the prerequisite
  that a worker must have executed at least once. Includes the helpful error
  message and remediation hints (claw or claw prompt <text>) so users
  discovering the command for the first time see actionable guidance.

These sections complement the product fixes in #142 (init JSON structure)
and #139 (state error actionability) by documenting the contract from a
user perspective.

Related: ROADMAP #142 (structured init output), #139 (worker-state discoverability).

YeonGyu-Kim 541c5bb95d feat: #139 actionable worker-state guidance in claw state error + help
Previously `claw state` errored with "no worker state file found ... — run a
worker first" but there is no `claw worker` subcommand, so claws had no
discoverable path from the error to a fix.

Changes:
- Rewrite the missing-state error to name the two concrete commands that
  produce .claw/worker-state.json:
    * `claw` (interactive REPL, writes state on first turn)
    * `claw prompt <text>` (one non-interactive turn)
  Also tell the user what to rerun: `claw state [--output-format json]`.
- Expand the State --help topic with "Produces state", "Observes state",
  and "Exit codes" lines so the worker-state contract is discoverable
  before the user hits the error.
- Add regression test state_error_surfaces_actionable_worker_commands_139
  asserting the error contains `claw prompt`, REPL mention, and the
  rerun path, plus that the help topic documents the producer contract.

Verified live:
  $ claw state
  error: no worker state file found at .claw/worker-state.json
    Hint: worker state is written by the interactive REPL or a non-interactive prompt.
    Run:   claw               # start the REPL (writes state on first turn)
    Or:    claw prompt <text> # run one non-interactive turn
    Then rerun: claw state [--output-format json]

JSON mode preserves the full hint inside the error envelope so CI/claws
can match on `claw prompt` without losing the canonical prefix.

Full workspace test green except pre-existing resume_latest flake (unrelated).

YeonGyu-Kim 611eed1537 feat: #142 structured fields in claw init --output-format json
Previously `claw init --output-format json` emitted a valid JSON envelope but
packed the entire human-formatted output into a single `message` string. Claw
scripts had to substring-match human language to tell `created` from `skipped`.

Changes:
- Add InitStatus::json_tag() returning machine-stable "created"|"updated"|"skipped"
  (unlike label() which includes the human " (already exists)" suffix).
- Add InitReport::NEXT_STEP constant so claws can read the next-step hint
  without grepping the message string.
- Add InitReport::artifacts_with_status() to partition artifacts by state.
- Add InitReport::artifact_json_entries() for the structured artifacts[] array.
- Rewrite run_init + init_json_value to emit first-class fields alongside the
  legacy message string (kept for text consumers): project_path, created[],
  updated[], skipped[], artifacts[], next_step, message.
- Update the slash-command Init dispatch to use the same structured JSON.
- Add regression test artifacts_with_status_partitions_fresh_and_idempotent_runs
  asserting both fresh + idempotent runs produce the right partitioning and
  that the machine-stable tag is bare 'skipped' not label()'s phrasing.

Verified output:
- Fresh dir: created[] has 4 entries, skipped[] empty
- Idempotent call: created[] empty, skipped[] has 4 entries
- project_path, next_step as first-class keys
- message preserved verbatim for backward compat

Full workspace test green except pre-existing resume_latest flake (unrelated).

YeonGyu-Kim 7763ca3260 feat: #141 unify claw <subcommand> --help contract across all 14 subcommands
Previously, `claw <subcommand> --help` had 5 different behaviors:
- 7 subcommands returned subcommand-specific help (correct)
- init/export/state/version silently fell back to global `claw --help`
- system-prompt/dump-manifests errored with `unknown <cmd> option: --help`
- bootstrap-plan printed its phase list instead of help text

Changes:
- Extend LocalHelpTopic enum with Init, State, Export, Version, SystemPrompt,
  DumpManifests, BootstrapPlan variants.
- Extend parse_local_help_action() to resolve those 7 subcommands to their
  local help topic instead of falling through to the main dispatch.
- Remove init/state/export/version from the explicit wants_help=true matcher
  so they reach parse_local_help_action() before being routed to global help.
- Add render_help_topic() entries for the 7 new topics with consistent
  Usage/Purpose/Output/Formats/Related structure.
- Add regression test subcommand_help_flag_has_one_contract_across_all_subcommands_141
  asserting every documented subcommand + both --help and -h variants resolve
  to a HelpTopic with non-empty text that contains a Usage line.

Verification:
- All 14 subcommands now return subcommand-specific help (live dogfood).
- Full workspace test green except pre-existing resume_latest flake.

YeonGyu-Kim 27ffd75f03 fix: #140 isolate test cwd + env in punctuation_bearing_single_token test
Previously this test inherited the cargo test runner's CWD, which could contain
a stale .claw/settings.json with "permissionMode": "acceptEdits" written by
another test. The deprecated-field resolver then silently downgraded the
default permission mode to WorkspaceWrite, breaking the test's assertion.

Fix: wrap the assertion in with_current_dir() + env_lock() so the test runs in
an isolated temp directory with no stale config.

Full workspace test now passes except for pre-existing resume_latest flake
(unrelated to #140, environment-dependent, tracked separately).
