`claw agents --output-format json` was still wrapping the text report,
which meant automation could not distinguish empty inventories from
populated agent definitions. Add a dedicated structured handler in the
commands crate, wire the CLI to it, and extend the contracts to cover
both empty and populated agent listings.
Constraint: Keep text-mode `claw agents` output unchanged while aligning JSON behavior with existing structured inventory handlers
Rejected: Parse the text report into JSON in the CLI layer | brittle duplication and no reusable structured handler
Confidence: high
Scope-risk: narrow
Directive: Keep inventory subcommands on dedicated structured handlers instead of serializing human-readable reports
Tested: cargo test -p commands renders_agents_reports_as_json; cargo test -p rusty-claude-cli --test output_format_contract; cargo test --workspace; cargo fmt --check; cargo clippy --workspace --all-targets -- -D warnings
Not-tested: Manual invocation of `claw agents --output-format json` outside automated tests
The resumed slash-command path built a reduced status JSON payload by hand, so it drifted from the fresh status schema and dropped metadata like model, permission mode, workspace counters, and sandbox details. Reuse a shared status JSON builder for both code paths and tighten the resume regression tests to lock parity in place.
Constraint: Resume mode does not carry an active runtime model, so restored sessions continue to report the existing restored-session sentinel value
Rejected: Copy the fresh status JSON shape into the resume path again | would recreate the same schema drift risk
Confidence: high
Scope-risk: narrow
Directive: Keep resumed and fresh /status JSON on the same helper so future schema changes stay in parity
Tested: Reproduced failure in temporary HEAD worktree with strengthened resumed_status_command_emits_structured_json_when_requested
Tested: cargo test -p rusty-claude-cli resumed_status_command_emits_structured_json_when_requested --test resume_slash_commands -- --exact --nocapture
Tested: cargo test -p rusty-claude-cli doctor_and_resume_status_emit_json_when_requested --test output_format_contract -- --exact --nocapture
Tested: cargo test --workspace
Tested: cargo fmt --check
Tested: cargo clippy --workspace --all-targets -- -D warnings
Finish the remaining roadmap work by making direct CLI JSON output deterministic across the non-interactive surface, restoring the degraded-startup MCP test as a real workspace test, and adding branch-lock plus commit-lineage primitives so downstream lane consumers can distinguish superseded worktree commits from canonical lineage.
Constraint: Keep the user-facing config namespace centered on .claw while preserving legacy fallback discovery for compatibility
Constraint: Verification needed to stay clean-room and reproducible from the checked-in workspace alone
Rejected: Leave the output-format contract implied by ad-hoc smoke runs only | too easy for direct CLI regressions to slip back into prose-only output
Rejected: Keep commit provenance as free-form detail text | downstream consumers need structured branch/worktree/supersession metadata
Confidence: medium
Scope-risk: moderate
Directive: Extend the JSON contract through the same direct CLI entrypoints instead of adding one-off serializers on parallel code paths
Tested: python .github/scripts/check_doc_source_of_truth.py
Tested: cd rust && cargo fmt --all --check
Tested: cd rust && cargo test --workspace
Tested: cd rust && cargo clippy -p commands -p tools -p rusty-claude-cli --all-targets --no-deps -- -D warnings
Not-tested: full cargo clippy --workspace --all-targets -- -D warnings still reports unrelated pre-existing runtime lint debt outside this change set
