## What
The full governance system of the sibling projects, ported to this repository: `RULEFOLDER/`
(map, architecture, feature registry, coding conventions, security rules and findings,
API parity, contributing workflow, team table, generated changelog), five ADRs (the four
ported ones plus a new **ADR-005 — app-side scheduling**, the TikTok-specific architectural
decision), the three tools (`new_change.py`, `build_changelog.py`, `check_rules.py` — copied
verbatim, they are project-agnostic), the change-fragment template, and the git hooks
(pre-commit + commit-msg) with `core.hooksPath` configured. `AGENTS.md` becomes the entry point.
The initial application (CHG-20261013-RG-01) is recorded as the first fragment, so the
changelog starts complete.

## Why
The owner runs all three publishers under one workflow: every change recorded, every GUI
capability with an API twin, security reviewed per change, IDs that cannot collide between
people or parallel AI sessions. Porting the proven system — tools verbatim, prose adapted to
this codebase — costs one change and removes all future argument about process.

## How
- **Tools copied verbatim** from FacebookManager (only the generated changelog's title string
  was adapted): they locate the project relative to their own path and reference `DOC/API.md`
  and `app/routes/`, which exist here.
- **Prose rewritten against this codebase**: `ARCHITECTURE.md` documents the two-container
  shape and the scheduling/token-refresh flows; `FEATURE-REGISTRY.md` lists the 19 real
  features with their real routes — `check_rules.py --parity` verifies it against the code and
  `DOC/API.md` (and caught one real gap while writing it: the GUI's retry button had no API
  twin, so `POST /api/v1/scheduled/{id}/retry` was added to keep parity structural);
  `SECURITY.md` keeps the mandatory rules and opens this project's own findings register
  (TT-S-01..09, including the two-writer SQLite note).
- **ADR-005 is new**, not ported: TikTok's Content Posting API has no scheduled publish, and
  the decision to schedule app-side (table + persistent media folder + a dedicated one-writer
  scheduler container, no scheduler library) is exactly the kind of decision an ADR exists for.
- **Hooks**: `.githooks/pre-commit` runs `check_rules.py --staged`; `.githooks/commit-msg`
  enforces the `CHG-YYYYMMDD-DEV-NN:` first line. Installed with
  `git config core.hooksPath .githooks` (the repository also needed a one-time
  `safe.directory` exception — this drive does not record ownership).

## API impact
One endpoint was added to keep parity structural (see `## How`):
`POST /api/v1/scheduled/{id}/retry` — re-queues a failed scheduled post; documented in
`DOC/API.md` §11.5 and registered in `FEATURE-REGISTRY.md`. No other endpoint changed.
`check_rules.py --parity` passes: every GUI route in code is registered with an API twin or a
reasoned browser exception, and every API endpoint in code is documented in `DOC/API.md`.

## Security review
- Inputs validated (type/length/allow-list/path)?           not applicable for the docs/tooling; the one new endpoint reuses the existing guards and service function
- Every new route has the right guard?                       yes — `POST /api/v1/scheduled/{id}/retry` is behind `@api_key_required` and requires an explicit account
- Any GET that changes state?                                no
- Secrets, tokens, personal data touched/logged/returned?    no — the fragments and rules contain no secrets; `SECURITY.md` §4 records the open findings honestly
- New dependency? pip-audit clean?                           n/a — the tools use only the Python standard library
- Mutating API endpoint requires explicit account?           yes — the retry endpoint (tested)
- Error messages safe (code + message, no exception text)?   yes — fixed messages
- Audit log written for mutations?                           n/a

## Verification
- `python RULEFOLDER\tools\build_changelog.py` → `CHANGELOG.md` rebuilt from 2 fragments.
- `python RULEFOLDER\tools\check_rules.py` → **All rule checks passed** (fragments valid, parity
  clean, changelog fresh).
- `.venv\Scripts\python -m pytest` → 61 passed (60 from CHG-20261013-RG-01 plus the new retry
  endpoint test).
- `git config core.hooksPath` → `.githooks`; `git status` works after the `safe.directory`
  exception.
