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real workspace test, and adding branch-lock plus commit-lineage primitives so downstream lane consumers can distinguish superseded worktree commits from canonical lineage.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
The landed mock Anthropic harness now covers multi-tool turns, bash flows,
permission prompt approve/deny paths, and an external plugin tool path.
A machine-readable scenario manifest plus a diff/checklist runner keep the
new scenarios tied back to PARITY.md so future additions stay honest.
Constraint: Must build on the deterministic mock service and clean-environment CLI harness
Rejected: Add an MCP tool scenario now | current MCP tool surface is still stubbed, so plugin coverage is the real executable path
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep rust/mock_parity_scenarios.json, mock_parity_harness.rs, and PARITY.md refs in lockstep
Tested: cargo fmt --all
Tested: cargo clippy --workspace --all-targets -- -D warnings
Tested: cargo test --workspace
Tested: python3 rust/scripts/run_mock_parity_diff.py
Not-tested: Real MCP lifecycle handshakes; remote plugin marketplace install flows
This adds a deterministic mock Anthropic-compatible /v1/messages service,
a clean-environment CLI harness, and repo docs so the first parity
milestone can be validated without live network dependencies.
Constraint: First milestone must prove Rust claw can connect from a clean environment and cover streaming, tool assembly, and permission/tool flow
Constraint: No new third-party dependencies; reuse the existing Rust workspace stack
Rejected: Record/replay live Anthropic traffic | nondeterministic and unsuitable for repeatable CI coverage
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep scenario markers and expected tool payload shapes synchronized between the mock service and the harness tests
Tested: cargo fmt --all
Tested: cargo clippy --workspace --all-targets -- -D warnings
Tested: cargo test --workspace
Tested: ./scripts/run_mock_parity_harness.sh
Not-tested: Live Anthropic responses beyond the five scripted harness scenarios
