v1.14.0: style: ruff-format page_path.py after symbol move

[1.14.0] - 2026-07-16

Catalog write-safety, leaf-module dependency direction, and Clean Code Tier F closures

Reliability and architecture hardening after the 2026-07-16 deep code audit. Builds on v1.13.1 (parser 1.6.0 alignment). No intentional MCP/CLI surface break for vault operators.

Fixed

• MasterCatalog write-safety (#210 / #211) — remove() followed by upsert() of the same title no longer loses the entry on save() (upsert clears a pending removal); corrupt / non-dict catalog JSON is logged and quarantined during merge-save instead of silently treated as empty; prune_missing_pages() records its removals so a plain save cannot undo a prune; get_case_insensitive uses a cached casefold index (invalidated on write) instead of a full linear scan under the lock.
• File watcher (#211) — handles on_moved events (rename routed as delete+create); replaced per-file threading.Timer fan-out with a single-thread debounce scheduler.
• Leaf-module import cycles (#215 / #216) — 4 of 5 deferred-import cycles resolved by relocating symbols to their true lowest-layer home: DaemonState / phase-2 progress metrics from daemon_state.py / daemon_page_queue.py (not via maintenance_daemon re-exports); lint handlers use daemon.ast_cache directly; shared canonicalize_llm_base_url() in llm_url_policy.py; resolve_existing_page_title moved to alias_index.py. One Tana cycle left intentional (test monkeypatch constraint).

Added

• Graph → rag boundary guard (#171 / #192) — tests/test_graph_layer_boundary.py forbids src/graph/ → src/rag/ imports in CI; allowlists generational_cache.py (lazy tokenize import) for a follow-up extraction. Thanks to @Maqbool61.
• Env clamp-contract tests (#173 / #187) — parametrized contracts for MATRYCA_LINK_VERIFY_STRIKES / BATCH / TIMEOUT and MATRYCA_GENERATIONAL_CACHE_MAX_GRAPHS (bounds, invalid strings, empty → defaults). Thanks to @Maqbool61.
• Deep code audit report — docs/AUDIT_REPORT_2026-07-16.md with F1–F11 findings, remediation status, and Mermaid architecture / sequence diagrams; CONTRIBUTING and good-first guides gain matching lifecycle diagrams.

Changed

• Shared env_parse adoption (Tier F) — concurrency_probe uses env_bool("MATRYCA_ALLOW_FLOCK_DEGRADATION") instead of a private helper (#172 / #188); plumber_config drops the _env_int shim so agent modules call utils.env_parse.env_int directly (#170 / #191). Thanks to @Maqbool61.
• Dependencies — Sovereign UI frontend npm group bumps (#190, #218); astral-sh/setup-uv in the github-actions Dependabot group (#189, #195).
• Documentation — README star-history section and duplicate header fix; docs aligned to post-audit code state; PROJECT_DIARY records F1–F11 remediation.
