Keep malformed diff invocations with trailing JSON format flags on the parser error path and lock the contract with focused output-format regressions.
Constraint: Do not touch tracked .omx state files.
Rejected: Repeating direct binary smoke loops | local auth/provider configuration intercepts those invocations and obscures parser behavior.
Confidence: high
Scope-risk: narrow
Tested: git diff --check; cargo fmt --check; cargo test -p rusty-claude-cli diff_extra_args_have_typed_error_kind_and_hint_766 --test output_format_contract; cargo test -p rusty-claude-cli diff_trailing_json_after_malformed_args_is_bounded_json_3129 --test output_format_contract; cargo test -p rusty-claude-cli diff_non_git_dir_has_error_kind_and_hint_801 --test output_format_contract
Two classifier arms had no corresponding assert_eq! in
test_classify_error_kind_returns_correct_discriminants: invalid_history_count
(both prefix and contains paths) and unknown_option (#790). Now 49/39 = full
coverage of all classify_error_kind return values.
claw '' and claw ' ' returned empty_prompt + hint:null because the
error message had no newline delimiter. Added usage hint. 61 CLI
contract tests pass.
Parity with #791 (config extra-arg fix). The plugins arg parser emitted
'unexpected extra arguments after claw plugins show ...' with no newline
delimiter, so split_error_hint returned None. Added usage hint after newline.
60 CLI contract tests pass.
Use git rev-parse --git-dir so startup preflight follows worktree .git indirections to the real metadata directory, then check directory permission metadata without creating probe files. Add a regression that verifies both the warning kind and structured event path for a read-only external gitdir.
Constraint: ROADMAP #695 requires early startup/worktree diagnostics without destructive writes or broad sandbox redesign.
Rejected: write-probe detection | it mutates git metadata during a diagnostic path.
Confidence: high
Scope-risk: narrow
Directive: Keep startup preflight warnings non-destructive and structured by warning kind/path.

The analog RAG/bootstrap formatter already rejected missing and literal unknown phases, but still accepted arbitrary phase strings. Keep the parser aligned with the runtime/service contract by allowlisting the known emitted phases and returning the existing typed error shape with received value and field context when drift appears.
Constraint: Scope is limited to claw-analog bootstrap/RAG phase parsing for ROADMAP #693.
Rejected: Preserve arbitrary non-empty phases | would continue hiding producer/parser phase drift.
Confidence: high
Scope-risk: narrow
Directive: Update KNOWN_RAG_BOOTSTRAP_PHASES when claw-rag-service deliberately adds a new response phase.

Guard the local/no-credential JSON command sweep so future additions fail fast when action is absent or empty.
Constraint: ROADMAP #710-#713 fixed most JSON surfaces; #714 dogfood sweep found remaining help and sandbox gaps.
Rejected: Schema redesign for help output | outside the action-field contract scope.
Confidence: high
Scope-risk: narrow
Directive: Keep --output-format json envelopes carrying a stable non-empty action on every local CLI surface.

Preserve session-list consumers from depending on encoded session IDs by carrying persisted creation timestamps through managed summaries and JSON detail output, with an ID timestamp fallback only for legacy metadata that lacks created_at_ms.\n\nConstraint: ROADMAP #335 requires created_at_ms in session_details with the same millisecond unit as updated_at_ms.\nRejected: Making callers parse session IDs | undocumented ID structure is brittle and was the issue being fixed.\nRejected: Session storage redesign | scope is limited to detail metadata propagation and legacy compatibility.\nConfidence: high\nScope-risk: narrow\nDirective: Keep ID timestamp parsing fallback-only; persisted session_meta.created_at_ms remains the source of truth when present.\nTested: cargo fmt --manifest-path rust/Cargo.toml --all -- --check; cargo check --manifest-path rust/Cargo.toml --workspace; cargo build --manifest-path rust/Cargo.toml --workspace; cargo test --manifest-path rust/Cargo.toml --workspace; cargo clippy --manifest-path rust/Cargo.toml -p runtime -p rusty-claude-cli --all-targets\nNot-tested: live interactive /session list against a real provider-backed REPL
