## [Unreleased]

### Added

- **Hermes FastMCP scaffold lane**: Added bundled scaffold script at `src/codomyrmex/agents/hermes/optional-skills/mcp/fastmcp/scaffold_fastmcp.py` to generate minimal FastMCP server packages for Codomyrmex↔Hermes MCP exposure.
- **`HermesClient.scaffold_fastmcp()`**: New client helper that resolves and executes the scaffold script with overwrite protection.
- **`hermes_fastmcp_scaffold` MCP tool**: Exposes FastMCP scaffolding through the Hermes MCP surface.
- **DAF Paperclip release milestone**: `projects/daf-consulting` advanced to `v0.4.1` with health-attempt telemetry artifacts, executable bootstrap artifact audit CLI, and end-to-end zero-mock CLI coverage for setup/audit flows.
- **Import-linter contract (LP5)**: `pyproject.toml` now declares a 4-layer architectural contract (Foundation → Core → Service → Application) enforced via `uv run lint-imports`. 5 known violations carved out with TODO comments for follow-up.
- **`config_management.defaults` constants**: Three new constants centralize hardcoded URLs — `DEFAULT_PAPERCLIP_URL`, `DEFAULT_VIDEO_TRANSCRIPTION_URL`, `DEFAULT_CORS_ALLOWED_ORIGINS`. All resolve via `os.getenv()` for env-var overrides.
- **Version stamp headers** on `docs/PAI_DASHBOARD.md`, `docs/DEPENDENCIES.md`, `docs/index.md` (previously missing).
- **Doc frontmatter `Last Updated`** field added to all 7 `docs/cognitive/*.md` + 11 `docs/bio/*.md` files (previously had it only in `docs/agi/`).
- **Cross-link** between `docs/bio/superorganism.md` and `docs/agi/the_colony_thesis.md`.

### Changed

- **`CodeReviewer._detect_language`**: Restored extension-to-`Language` mapping on `coding/review/reviewer.py` so `TraditionalMixin` / `PyscnMixin` and `test_reviewer_analysis` run against a real method (regression after mixin refactor).
- **Security secrets / NumPy `randbits`**: `security/secrets/vault.py` loads stdlib `secrets` with `importlib` + `sysconfig` (no `sys.modules['secrets']` mutation). **`tests/unit/security/secrets/`** renamed to **`secrets_tests/`** so `sys.path` entries under `tests/unit/security` no longer resolve `import secrets` to the test package (fixes `ImportError: cannot import name randbits` in NumPy and Hypothesis). `HYPOTHESIS_NO_NPY=1` remains on CI/release `env`, Makefile `export`, and conftest mirrors; see `RUNNING_TESTS.md` / `CLAUDE.md`.
- **Pytest / coverage defaults**: Removed `--cov` and related flags from default pytest `addopts` in `pyproject.toml` so `uv run pytest` runs without measuring coverage. The **40%** floor remains in `[tool.coverage.report] fail_under` and is applied when using `--cov` (e.g. `make test`, CI unit job, or manual `--cov-fail-under=40`).
- **Coverage scope**: `src/codomyrmex/meme/` is listed in `[tool.coverage.run] omit` (experimental module); statement coverage is measured for the rest of `src/codomyrmex/`.
- **CI**: Added `coverage-gate` job in `.github/workflows/ci.yml` (full `src/codomyrmex/tests/` with `--cov-fail-under=40`, no `continue-on-error`); `build-package` depends on it. **Release** workflow uses `--cov-fail-under=40` on the unit tree.
- **Makefile**: `verify-release` target runs `lint`, `type-check`, and `test` (40% gate).
- **Code Health & Zero-Mock Enforcement**: Resolved 446 `ruff` diagnostic errors across the ecosystem. Enforced strict Zero-Mock compliance by removing legacy mock-dependent test adapters for the `open_gauss` agent.
- **Paperclip workspace surfaces**: Root and `projects/` docs now explicitly track Paperclip adapter/integration workspaces; `projects/hermes-paperclip-adapter` is treated as an intentional standalone nested repository pending writable upstream publication.
- **Doc version stamps** harmonized to v1.2.7 across all 19 `docs/` subdirectories (previously 14 were stale at v1.2.3).
- **`docs/reference/inventory.md`** — timestamp refreshed (2026-05-13 → 2026-05-21); `Markdown files under docs/` count updated 1,164 → 1,172 (caught drift).
- **`docs/pai/tools-reference.md`** — static-tool count corrected 22 → 20 (matches `TOOL_DEFINITIONS` length empirically).
- **`docs/AGENTS.md`** — "200+ markdown files" → "1,172" with link to `inventory.md`.
- **`docs/index.md`** — "15-tab SPA dashboard" → "14-tab" + link to `PAI_DASHBOARD.md` (matches the canonical 14-subsystem list).
- **`docs/agi/`** module-count contradictions reconciled to 128 across `scaffolding.md` (line 17), `the_colony_thesis.md` (lines 173, 218), `recursive_self_improvement.md` (line 82); `memory_and_continuity.md` heading "Four-Tier" → "Five-Tier" to match content.
- **`docs/bio/myrmecology.md`** — Formicidae species count corrected from "over 22,000 described" to "over 14,000 valid extant species (Bolton 2024 / AntCat), with several thousand additional subspecies and fossil taxa" (the 22k figure conflated extant + subspecific + fossil taxa).
- **`docs/agi/emergence_and_scale.md`** line 21: clarified bond-percolation vs site-percolation interpretation of Molloy-Reed threshold.
- **`docs/cognitive/active_inference.md`** line 11: added "F measured in nats; multiply by 1/ln 2 ≈ 1.443 for bits" units clarification.
- **`docs/agi/the_colony_thesis.md`** line 79: added Hofstadter strange-loop vs tangled-hierarchy distinction.
- **`projects/test_project/src/llm_inference.py`**: `OllamaModel.get()` (dict access on dataclass) → `getattr()`; `OllamaManager.list_models()` now returns 7 models on systems with Ollama running (was 0); `TaskDecomposer.decompose()` called with `description` string instead of `Task` object (decomposer uses `.lower()` internally).
- **`projects/test_project/src/security_audit.py`**: `SystemDiscovery.discover_modules()` (missing method) → `scan_system()`.
- **`projects/test_project/src/mcp_explorer.py`**: `MCPDiscovery.discover()` → `scan_package() + list_tools()`; `generate_taxonomy_report()` and `categorize_all_tools()` now passed required `tool_names` arg; `SkillRegistry.list_skills()` → `build_index() + get_categories()`.
- **`projects/test_project/src/knowledge_search.py`**: `verify_constraints()` now uses `importlib.util.find_spec("z3")` guard, returns clean error message instead of `NameError: name 'z3' is not defined`.
- **`projects/test_project/src/{README,SPEC,PAI}.md`**: regenerated content from boilerplate "Validation coverage" stub to accurate descriptions of the zero-mock reference implementation; `SPEC.md` mermaid diagram now includes the 6 integration-layer modules (`agent_brain`, `git_workflow`, `knowledge_search`, `security_audit`, `mcp_explorer`, `llm_inference`); `PAI.md` tree expanded from 5 to 11 src files.
- **`src/codomyrmex/agentic_memory/core/memory.py`**: hardcoded `http://localhost:11434/api/embed` → `os.getenv("OLLAMA_BASE_URL", "http://localhost:11434")` per "No silent fallbacks" + "No hardcoded values" policies.
- **`src/codomyrmex/agentic_memory/memory.py`**: 528-line byte-near-identical duplicate of `core/memory.py` collapsed to 19-line re-export shim. Surfaced and fixed a latent `rr.relevance` → `rr.relevance_score` `AttributeError` carried by the old duplicate.
- **`src/codomyrmex/cli/core.py`**: module docstring added (entry point listed in `[project.scripts]`).
- **`src/codomyrmex/cli/mcp_tools.py`** + **`src/codomyrmex/agents/pai/trust_gateway.py`**: docstring capitalizations + stale line-reference comment removal.
- **`src/codomyrmex/__init__.py`**: `"tests"` removed from `__all__` (kept in `_submodules` lazy-load list for legitimate internal use).
- **`src/codomyrmex/video/transcription.py`**: `_DEFAULT_API_URL` now reads `os.getenv("VIDEO_TRANSCRIPTION_URL", DEFAULT_VIDEO_TRANSCRIPTION_URL)`.
- **`src/codomyrmex/agents/paperclip/{paperclip_api_client,paperclip_client,mcp_tools}.py`**: 4 hardcoded `http://localhost:3100` defaults replaced with `base_url or os.getenv("PAPERCLIP_BASE_URL", DEFAULT_PAPERCLIP_URL)` sentinel pattern.
- **`src/codomyrmex/website/server.py`**: CORS allow-list now reads `os.getenv("CORS_ALLOWED_ORIGINS", DEFAULT_CORS_ALLOWED_ORIGINS)`.
- **`src/codomyrmex/website/pai_mixin.py`**: localhost host now reads `os.getenv("PM_SERVER_HOST", "localhost")`.

### Tests

- Added unit coverage for FastMCP scaffolding in `test_new_client_methods.py` and `test_new_mcp_tools.py` (real filesystem writes; no mocks).
- `secrets_tests/test_secrets.py`: regression test that `generate_secret` leaves stdlib `secrets.randbits` and `numpy.random` usable.

### Documentation

- **Deep-review pass (rounds 1+2)**: 8 specialist + 7 specialist agent dispatches across two rounds; 95+ files modified outside the pre-existing Docusaurus mirror; ~16/16 round-2 ISCs `[x]` with quoted artifacts in `~/.claude/PAI/MEMORY/WORK/codomyrmex-deep-review-2026-05-21/ISA.md`.

## [1.2.4] - 2026-03-18 — "Google Affordances & Auth Unification"

Unified OAuth2 env var pattern across all Google integrations. PAI can now send Gmail and manage Google Calendar without a credentials file.

### Added

- **email/gmail**: `GmailProvider.from_env()` — OAuth2 env var constructor (`GOOGLE_CLIENT_ID` + `GOOGLE_CLIENT_SECRET` + `GOOGLE_REFRESH_TOKEN`) with ADC fallback
- **email/mcp_tools**: 4 Gmail MCP tools — `gmail_send_message`, `gmail_list_messages`, `gmail_get_message`, `gmail_create_draft`; PAI can now send Gmail directly via <FristonBlanket@gmail.com>
- **calendar_integration/gcal**: `GoogleCalendar.from_env()` — same unified OAuth2 env var pattern as `GmailProvider`
- **tests/integration/email**: 11-test integration suite (9 skip without live creds); covers send/list/get/retrieve and MCP tool layer end-to-end

### Changed

- **calendar_integration/mcp_tools**: `_get_provider()` now prefers `GOOGLE_REFRESH_TOKEN` env vars (token-file path is legacy fallback)

### Fixed

- `calendar_integration/README.md`: Wrong default attendee email corrected (`danielarifriedman@gmail.com` → `FristonBlanket@gmail.com`)
- `email/API_SPECIFICATION.md`: Wrong env var corrected (`GOOGLE_CREDENTIALS` → `GOOGLE_CLIENT_ID` + `GOOGLE_CLIENT_SECRET` + `GOOGLE_REFRESH_TOKEN`)
- `email/PAI.md`: Now documents all 12 MCP tools (8 AgentMail + 4 Gmail)

### Metrics

| Metric | Before | After |
|--------|--------|-------|
| Gmail MCP tools | 0 | **4** |
| Google auth pattern | per-provider ad hoc | **unified `from_env()` OAuth2** |
| Email integration tests | 0 | **11** (9 skip without live creds) |


---

## [1.2.3] - 2026-03-16 — "Coherence Release"

Repo-wide structural coherence audit and reconciliation.

### Fixed

- **Version sync**: Reconciled version mismatch — `pyproject.toml` (1.2.2), `__init__.py` (1.1.9), `README.md` (1.1.9), `SPEC.md` (1.1.9) → all aligned to **1.2.3**
- **Module registration**: 39 modules existed on disk but were missing from `__init__.py` `_submodules` and `__all__` — now all 128 registered and lazy-importable
- **Coverage config**: Reconciled contradictory `fail_under` values (75/40/33%) → unified to **40%**
- **Python classifier**: Removed misleading `Python :: 3.10` classifier (project requires `>=3.11`)
- **Spurious files**: Removed git-tracked junk files at repo root created by buggy type-annotation script
- **Sub-level versions**: Updated `src/README.md` (v0.1.0 → v1.2.3) and `src/codomyrmex/AGENTS.md` (v0.1.0 → v1.2.3)

### Metrics

| Metric | Before v1.2.3 | v1.2.3 |
|--------|--------|--------|
| **Registered modules** | 90 | **128** (38 added) |
| **Version files synced** | 1 | **7** |
| **Coverage gate** | inconsistent | **40%** (unified) |
