762. **`classify_error_kind` unit test missing coverage for 15 of 23 classifier arms** — dogfooded 2026-05-27 on `d83de563`. `classify_error_kind_returns_correct_discriminants` only asserted 8 of the 23 arms, leaving `missing_flag_value`, `invalid_flag_value`, `missing_prompt`, `interactive_only`, `unknown_agents_subcommand`, `agent_not_found`, `plugin_not_found`, `skill_not_found`, `unsupported_config_section`, `no_managed_sessions`, `legacy_session_no_workspace_binding`, `missing_manifests`, `unknown_plugins_action`, `unsupported_skills_action`, and `confirmation_required` uncovered. Any discriminant string drift would silently fall to `"unknown"` without a failing test. Fix: added 18 new `assert_eq!` invocations covering all previously untested arms.

763. **Config JSON parse errors fall to `error_kind:"unknown"`** — dogfooded 2026-05-27 on `88ce1810`. Malformed `.claw/settings.json` or `.claw.json` (unterminated string, type mismatch, unknown keys) produce serde_json errors like `"/path/.claw/settings.json: expected ',', found end of input"` but classify as `error_kind:"unknown"` + `hint:null`. Callers must regex the error message to route. Fix: added `config_parse_error` classifier arm that matches on presence of `.claw/settings.json` or `.claw.json` in the error message. All three error patterns now consistently produce `error_kind:"config_parse_error"`. Test coverage added. Source: Jobdori event/log opacity probe on `88ce1810`, 2026-05-27.
764. **`config_parse_error` returned `hint: null` despite #763 adding the classifier** — dogfooded 2026-05-27 on `c86dc73d`. #763 fixed `error_kind` classification but `hint` remained `null` because `ConfigError::Parse` Display impl emitted only the bare serde_json error string (no `\n` delimiter). `split_error_hint()` found nothing to split. Fix: updated `Display for ConfigError::Parse` in `runtime/src/config.rs` to append `\nFix: open the file shown above and correct the JSON syntax, then retry.`. Integration test `config_parse_error_has_typed_error_kind_and_hint_764` added to `output_format_contract.rs` asserting non-zero exit + `error_kind:config_parse_error` + non-empty hint. 31 contract tests pass.
