 - **Fail-closed authorization.** Every authorization decision denies when it
  cannot be positively verified. Resource-type authorization (`authz.py`)
  classifies each call (repository/org/user/admin/misc) and enforces a
  type-specific rule; admin is **default-deny**. The `gitea_request` escape

-## Tool Development Standards
+## Quality gates (must stay green; never commit red)
- Public functions require docstrings and type hints.
+- `make lint` — ruff check, ruff format --check, black --check, mypy (strict).
- Validate all tool inputs with strict schemas (`extra=forbid`).
+- `make test` — pytest with `--cov-fail-under=80` (do not lower the threshold).
- Enforce response size limits for list/text outputs.
+- Small, logical commits with conventional-commit messages.
 - Every tool must produce auditable invocation events.
 - New tools must be added to `docs/api-reference.md`.
-## Testing Requirements
+## Branching / contribution flow
-Every feature change must include or update:
+`HEAD -> feature branch -> dev -> main`. Branch features from `dev`. **All** pull
- Unit tests.
+requests target `dev`; `dev` is merged into `main` for releases. Never commit or
- Failure-mode tests.

- Policy allow/deny coverage where relevant.
+publish workflow runs on a `v*` tag.
 - Write-mode denial tests for write tools.
 - Security tests for secret sanitization and audit integrity where relevant.
 ## Documentation Rules
 - All new documentation files go under `docs/`.
 - Security-impacting changes must update relevant docs in the same change set.
 - Operational toggles (`WRITE_MODE`, policy paths, rate limits) must be documented with safe defaults.
 ## Review Standards
 Changes are reviewable only if they include:
 - Threat/abuse analysis for new capabilities.
 - Backward-compatibility notes.
 - Test evidence (`make test`, and lint when applicable).
 - Explicit reasoning for security tradeoffs.
 ## Forbidden Patterns
 The following are prohibited:
 - Default binding to `0.0.0.0` without explicit opt-in.
 - Silent bypass of policy engine.
 - Disabling audit logging for security-sensitive actions.
 - Returning raw secrets or unredacted credentials in responses.
 - Hidden feature flags that enable write actions outside documented controls.

 ## Architecture
-### Request Flow
+### Core + two adapters
 The package is a **transport-agnostic core** plus **two thin adapters**. The
 core never imports FastAPI/uvicorn — `tests/test_core_boundary.py` locks this by
 importing the core in a clean subprocess and asserting the web stack stays out.
 - **Core**: `registry.py` (single name→handler source of truth), `tools/*`,
  `policy.py`, `authz.py`, `gitea_client.py`, `audit.py`, `security.py`,
  `response_limits.py`, `config.py`, `request_context.py`, `errors.py`
  (`ToolError`, the transport-agnostic error type). Default `pip install`.
 - **HTTP/OAuth adapter**: `server.py` (FastAPI) — `[server]` extra. Entry point
  `aegis-gitea-mcp-server` (via guarded `server_entry.py`).
 - **Local stdio adapter**: `stdio_app.py` (official `mcp` SDK) — core install.
  Entry point `aegis-gitea-mcp`. Single PAT-owner identity, no OAuth.
 Both adapters dispatch the same tools from `registry.py`. Core handlers raise
 `errors.ToolError`; each adapter maps it to its transport (HTTP → `HTTPException`).
 ### Request Flow (HTTP adapter)
 ```
 AI Client (Bearer token)
  → FastAPI server.py
      → OAuth middleware (validate token via Gitea OIDC/JWKS)
      → Rate limiter (per-IP and per-token sliding windows)
-      → Policy engine (tool/repo/path allow-deny)
+      → Scope check → Policy engine (tool/repo/path allow-deny)
-      → Tool handler (tools/repository.py, read_tools.py, write_tools.py)
+      → Authorization:
          repository → per-user collaborator permission (service-PAT mode)
          org/user/admin/misc → resource-type-aware authz (authz.py, fail-closed)
      → Tool handler (registry.py → tools/*)
          → gitea_request: write classifier + known-path gate + admin denylist
          → Response limits (item count + text length)
          → Secret sanitization
          → gitea_client.py → Gitea API
  → Audit log (hash-chained, append-only)
 ```
 The **local stdio adapter** runs the same policy + `WRITE_MODE` + audit +
 sanitization, but trusts the PAT owner and skips the per-user repository probe.

 ## Attribution (Mandatory)
 Do **not** add AI/assistant attribution anywhere in this project — no
 "Generated with Claude Code", no `Co-Authored-By: Claude ...` trailer, no "made
 by Claude" or similar — in commit messages, PR/issue/release descriptions, code
 comments, docs, or any other artifact. Write all commit and PR text as the
 project's own work. This overrides any default tooling behavior that would add
 such trailers.

 `stdio_app.py` serves the shared registry over stdio (`mcp` SDK). Invariant: the
 **stdout stream is reserved for JSON-RPC** — all logging must go to stderr
 (`_configure_stderr_logging()` enforces this). Build the server with
 `build_server()` (pure, testable in-process); `_serve()` resolves the PAT owner
 and runs it over real stdio. End-to-end coverage uses the `mcp` in-memory
 transport (`tests/test_stdio_app.py`).

 Flow: HEAD -> custom branch -> dev -> main. Never push directly to dev/main.
 Baseline (recorded Phase 0): 284 passed, 1 skipped, coverage 84.04%, threshold 80%.
 ## Phase checklist
 - [x] Phase 0 — Branch from dev, baseline recorded, PLAN.md committed.
 - [x] Phase 1 — Extract transport-agnostic core + shared tool registry (+ boundary test).
 - [x] Phase 2 — stdio adapter (`stdio_app.py`) + packaging (core + `[server]` extra, 0.2.0).
 - [x] Phase 3 — Resource-type-aware authorization (fail-closed).
 - [x] Phase 4 — gitea_request classifier + known-path gate (unknown path => deny).
 - [x] Phase 5 — Tests: authz matrix, write-mode bypass, classifier, stdio adapter, boundary.
 - [x] Phase 6 — Docs & README (local vs server quickstart, authz model, packaging, CLAUDE/AGENTS).
 - [ ] Phase 7 — `.gitea/workflows/publish.yml` (uv build + publish to Gitea registry on tag).
 - [ ] Phase 8 — Verify green + coverage >= baseline, `uv build`, push, open PR into dev.
 Note: version bumped to 0.2.0 (the app already reported 0.2.0; pyproject was 0.1.0).
 TODO(authz): make `list_organizations` user-scoped (`/users/{login}/orgs`) so it can
 be allowed rather than denied in service-PAT mode.
 ## Key deltas found during orientation
 - No single tool registry today: definitions in `mcp_protocol.AVAILABLE_TOOLS`,
  handlers in `server.TOOL_HANDLERS`. Phase 1 unifies them.
 - `tools/raw_tools.py` imports `fastapi.HTTPException` — the only core->web import to break.
 - Current authz is repo-only and lives in `server._verify_user_repository_access`.
 - stdio mode must run with `AUTH_ENABLED=false` (config otherwise requires MCP_API_KEYS).
 - `AGENTS.md` absent at root though CLAUDE.md cites it; create it from the contract.

 }
 ```
 The local server resolves your PAT's Gitea user at startup and pins every call to that identity. The policy engine and `WRITE_MODE` gate still apply (writes are off by default), and the audit log is written to a per-user path (e.g. `%LOCALAPPDATA%\aegis-gitea-mcp\audit.log` on Windows, `~/.local/state/aegis-gitea-mcp/audit.log` on Linux).

 Where the security layers sit on a dispatched call: **scope check → policy
 (`policy.py`) → resource-type authorization (`authz.py`) → handler → response
 limits + secret sanitization → audit**. For `gitea_request`, the handler adds a
 deterministic write classifier, a known-path gate, and the admin/credential
 denylist. The HTTP adapter runs the per-user repository-permission probe and the
 resource-type gate; the stdio adapter trusts the PAT owner and skips the
 per-user probe while keeping policy, `WRITE_MODE`, and audit.

 # Local quickstart (stdio)
 The local transport runs AegisGitea-MCP on your own machine as a single-user MCP
 server over stdio. It authenticates with **your** Gitea Personal Access Token
 (PAT) — there is no OAuth, no public endpoint, and no web stack to install.
 ## What you need
 - A Gitea instance URL (`GITEA_URL`).
 - A Gitea Personal Access Token (`GITEA_TOKEN`) with least privilege:
  - `read:repository`
  - `write:repository` only if you intend to enable `WRITE_MODE`.
 - [`uv`](https://docs.astral.sh/uv/) (for `uvx`) or `pip`.
 ## Run it
 With `uvx` (no install):
 ```bash
 GITEA_URL=https://git.hiddenden.cafe \
 GITEA_TOKEN=<pat> \
 uvx aegis-gitea-mcp
 ```
 With pip:
 ```bash
 pip install aegis-gitea-mcp
 GITEA_URL=https://git.hiddenden.cafe GITEA_TOKEN=<pat> aegis-gitea-mcp
 ```
 A local `.env` file is also supported — drop `GITEA_URL` and `GITEA_TOKEN` in it
 and just run `aegis-gitea-mcp`.
 If a required variable is missing the server exits with a clear message instead
 of a traceback.
 ## Wire it into a client
 Claude Code:
 ```bash
 claude mcp add aegis-gitea \
  -e GITEA_URL=https://git.hiddenden.cafe \
  -e GITEA_TOKEN=<pat> \
  -- uvx aegis-gitea-mcp
 ```
 Claude Desktop (`claude_desktop_config.json`):
 ```json
 {
  "mcpServers": {
    "aegis-gitea": {
      "command": "uvx",
      "args": ["aegis-gitea-mcp"],

        "GITEA_TOKEN": "<pat>"
      }
    }
  }
 }
 ```
 ## What still applies locally
 The local adapter is single-user and trusts the PAT owner, so it skips the
 per-user repository-permission probe used by the public server. Everything else
 is identical to the server:
 - **Policy engine** (`policy.yaml`) — same allow/deny rules.
 - **`WRITE_MODE`** — off by default; writes are denied unless explicitly enabled
  and whitelisted.
 - **`gitea_request`** full-API escape hatch — same write classifier, known-path
  gate, and admin/credential denylist.
 - **Secret sanitization** of tool output.
 - **Tamper-evident audit log** — written to a per-user path when the container
  default is not writable:
  - Windows: `%LOCALAPPDATA%\aegis-gitea-mcp\audit.log`
  - Linux/macOS: `$XDG_STATE_HOME/aegis-gitea-mcp/audit.log` or
    `~/.local/state/aegis-gitea-mcp/audit.log`
  - Override with `AUDIT_LOG_PATH`.
 ## Enabling writes locally
 Writes are opt-in, exactly as on the server:
 ```bash

 GITEA_TOKEN=<pat-with-write-repository> \
 WRITE_MODE=true \
 WRITE_REPOSITORY_WHITELIST=acme/app,acme/docs \

 # Packaging & publishing
 AegisGitea-MCP is built with [`uv`](https://docs.astral.sh/uv/) and published to
 the self-hosted Gitea package registry on every merge. There are two channels:
 | Channel | Package | Published on | Versioning |
 |---------|---------|--------------|------------|
 | **stable** | `aegis-gitea-mcp` | merge to `main` | `X.Y.Z` |
 | **dev** | `aegis-gitea-mcp-dev` | merge to `dev` | `X.Y.Z.devN` (N = CI run number, always unique) |
 Both channels build from the same source and install the **same import module**,
 `aegis_gitea_mcp`, with the same two console scripts. They differ only in the
 distribution name and the version. Install one or the other in a given
 environment, not both — they would collide on the module.
 ## Distribution layout
 Each channel ships one distribution with two console scripts and one optional
 extra (the stable and dev packages are identical here — only the dist name and
 version differ):
 | Console script | Entry point | Requires |
 |----------------|-------------|----------|
 | `aegis-gitea-mcp` | `aegis_gitea_mcp.stdio_app:main` | core only |
 | `aegis-gitea-mcp-server` | `aegis_gitea_mcp.server_entry:main` | `[server]` extra |
 - **Core** (default install): `httpx`, `pydantic`, `pydantic-settings`, `PyYAML`,
  `python-dotenv`, `structlog`, `mcp`. Enough to run the local stdio server.
 - **`[server]` extra**: `fastapi`, `uvicorn[standard]`, `PyJWT[crypto]`,
  `python-multipart`. The public HTTP/OAuth server.
 The `aegis-gitea-mcp-server` entry point degrades gracefully: invoked without
 the web stack it prints `install 'aegis-gitea-mcp[server]'` instead of a
 `ModuleNotFoundError` traceback.
 ## Build locally
 ```bash
 uv build
 # -> dist/aegis_gitea_mcp-<version>-py3-none-any.whl
 # -> dist/aegis_gitea_mcp-<version>.tar.gz
 ```
 Smoke-test the local stdio server from the built wheel:
 ```bash
 GITEA_URL=https://git.hiddenden.cafe GITEA_TOKEN=<pat> \
  uvx --from ./dist/aegis_gitea_mcp-*.whl aegis-gitea-mcp
 ```
 ## Install from the Gitea registry
 **Stable** (`aegis-gitea-mcp`, published from `main`):
 ```bash
 uv pip install \
  --index-url https://git.hiddenden.cafe/api/packages/Hiddenden/pypi/simple/ \
  aegis-gitea-mcp
 # or run it one-off without installing into the environment:
 uvx --index https://git.hiddenden.cafe/api/packages/Hiddenden/pypi/simple/ aegis-gitea-mcp
 ```
 **Dev** (`aegis-gitea-mcp-dev`, published from `dev` — newest pre-release build):
 ```bash
 uv pip install \
  --index-url https://git.hiddenden.cafe/api/packages/Hiddenden/pypi/simple/ \
  aegis-gitea-mcp-dev
 ```
 (With `pip`, use `--index-url` the same way.) Both packages expose the same
 `aegis-gitea-mcp` / `aegis-gitea-mcp-server` console scripts and the same
 `aegis_gitea_mcp` import module, so install one **or** the other per environment.
 ## Publishing channels
 Publishing is merge-driven, not tag-driven. The publish workflow
 (`.gitea/workflows/publish.yml`) triggers on a push to `dev` or `main`, runs
 lint + tests first, then builds with `uv` and publishes to the Gitea PyPI
 registry. The package name + version are patched into `pyproject.toml` **at build
 time only** (never committed):
 - **`dev` push** → `aegis-gitea-mcp-dev` at `X.Y.Z.dev<run_number>`. The CI run
  number is monotonic, so every merge to `dev` yields a unique pre-release.
 - **`main` push** → `aegis-gitea-mcp` at the plain `X.Y.Z` from `pyproject.toml`.
  Publishing uses `uv publish --check-url`, so a `main` push that did **not** bump
  the version is a clean no-op (the existing files are skipped) rather than a 409.
 ### Cutting a stable release
 1. Bump `version` in `pyproject.toml` (e.g. `0.2.0` → `0.3.0`) on a branch off
   `dev`.
 2. Open a PR into `dev` and merge it (this publishes a fresh
   `aegis-gitea-mcp-dev` build).
 3. Promote `dev` → `main`. The push to `main` publishes the new stable
   `aegis-gitea-mcp X.Y.Z`.
 Re-pushing `main` at an unchanged version is harmless — `--check-url` skips the
 already-published files.
 ### Required CI secrets
 The publish job reuses the **existing** `REGISTRY_TOKEN` Actions secret — the same
 PAT (`write:package`) that `docker.yml` uses to push images — so no new secret is
 needed. The token authenticates as its owning Gitea user, so `GITHUB_ACTOR` is the
 username and the token is the password.
 | Secret | Purpose |
 |--------|---------|
 | `REGISTRY_TOKEN` | PAT with `write:package`; used for both image and package pushes |
 If the secret is absent the job fails loudly rather than publishing anonymously.
 > Publishing to public PyPI is intentionally **not** configured. A second,
 > separately-gated `uv publish` step would be required and is left as a
 > commented stub in the workflow.

 # Raw API Dispatch (`gitea_request`)
 `gitea_request` is a generic escape hatch that can call **any** Gitea REST
 endpoint by method and path. It exists for the long tail of the Gitea API that
 the curated, typed tools do not cover (merging PRs, reviews, writing files,
 webhooks, branch/tag protections, collaborators, Actions/CI, packages,
 notifications, and so on).
 > Prefer the dedicated tools whenever one exists. Use `gitea_request` only for
 > endpoints they do not cover. It is subject to policy, write-mode, and the
 > sensitive-path denylist described below.
 ## Arguments
 | Field | Type | Notes |
 |-------|------|-------|
 | `method` | enum | `GET`, `HEAD`, `POST`, `PUT`, `PATCH`, `DELETE` (case-insensitive). Any other method is rejected before any network call. |
 | `path` | string | Gitea REST path. The `/api/v1` prefix is optional. A full URL may be supplied — the host and query string are stripped. |
 | `query` | object | Optional query-string parameters. |
 | `body` | object | Optional JSON request body. **Never logged.** |
 The response is returned in a stable envelope:
 ```json
 {
  "method": "GET",
  "path": "/api/v1/repos/acme/app/pulls/1",
  "write": false,
  "repository": "acme/app",
  "data": { "...": "..." }
 }
 ```
 List responses add `count` and `omitted`; oversized objects are returned as a
 truncated JSON string with `"truncated": true`. All responses are bounded by
 `MAX_TOOL_RESPONSE_ITEMS` / `MAX_TOOL_RESPONSE_CHARS`.
 ## Two-layer authorization
 A single tool surface would normally collapse the granularity of `policy.yaml`.
 To preserve it, every call is authorized twice:
 1. **Central gate (`server.py`).** The registered `gitea_request` tool name is
   allowed/denied like any other tool. In service-PAT mode the central gate also
   parses the target repository from the path and verifies that the signed-in
   user has permission on that repository before the service PAT is used.
 2. **Handler gate (`raw_tools.py`).** The handler derives a coarse **virtual
   tool name** of the form `gitea_request:<METHOD>:<top-path-segment>` (for
   example `gitea_request:GET:repos` or `gitea_request:DELETE:repos`) and runs
   it back through the policy engine with the parsed repository, target path, and
   a `is_write` flag (`true` for any method other than GET/HEAD). This reuses the
   existing write-mode + write-whitelist enforcement and lets `policy.yaml` allow
   or deny raw dispatch per method and per top-level path segment.
 Because the policy engine matches tool names by **exact set membership** (only
 `paths` use globbing), the virtual name is deliberately coarse and stable.
 ### Example: lock raw dispatch to reads
 ```yaml
 tools:
  deny:
    - gitea_request:POST:repos
    - gitea_request:PUT:repos
    - gitea_request:PATCH:repos
    - gitea_request:DELETE:repos
 ```
 ## Sensitive-path denylist
 Independently of `policy.yaml`, the handler blocks endpoints that touch an
 admin or credential surface **for every method, including GET** (a GET on these
 already leaks credentials or privileged configuration):
 - `/admin`
 - `*tokens*`
 - `*secrets*`
 - `*hooks*`
 - `*keys*` (and `*gpg_keys*`)
 - `applications/oauth2`
 - `actions/runners/registration-token`
 This denylist lives in the handler and **cannot be re-opened from
 `policy.yaml`.** It is overridden only by setting `RAW_API_ALLOW_SENSITIVE=true`.
 ## Configuration
 | Variable | Default | Notes |
 |----------|---------|-------|
 | `RAW_API_ENABLED` | `true` | Killswitch. When `false`, `gitea_request` refuses every dispatch with a `403`. |
 | `RAW_API_ALLOW_SENSITIVE` | `false` | When `true`, the admin/credential denylist is bypassed. Leave `false` unless you fully understand the exposure. |
 ## Security warning
 > With `WRITE_MODE=true`, the **write whitelist is the only brake** on
 > `POST`/`PUT`/`PATCH`/`DELETE` across the *entire* Gitea API surface reachable
 > by `gitea_request`. Any write method against a whitelisted repository will be
 > attempted. Keep the whitelist tight, prefer denying the write virtual tool
 > names in `policy.yaml`, and keep `RAW_API_ALLOW_SENSITIVE=false`.
 ## Behavioral notes and edge cases
 - **Full URL supplied instead of a path:** only the path is used; the host and
  query string are discarded (`query` carries query parameters).
 - **Path traversal (`..`):** rejected during argument validation (`400`).
 - **Unknown / non-HTTP method:** rejected during argument validation, before any
  network call.
 - **Cross-repo endpoints** such as `/repos/search` and `/repos/issues/search`
  are intentionally *not* treated as repository-scoped, so `repository` is
  `null` for them.
 - **Non-repository writes** such as `POST /user/repos` or `POST /orgs` are denied
  with *"write operation requires a repository target"*. This is the secure
  default — the per-user permission model is repository-scoped, so there is no
  repository against which to verify the write. This behavior is intentional and
  is not worked around.
 - **Service-PAT mode:** non-repository endpoints (for example `GET /user/orgs`)
  are denied by the central gate because per-user permission can only be verified
  against a repository target. Use the dedicated tools for those, or run in
  OAuth-only mode.

+- A compromised token is limited to that user�s permissions.
 ## Resource-type-aware authorization
 The public server runs in *service-PAT mode*: a privileged bot token makes the
 actual Gitea calls while the per-user OAuth identity decides what the user may
 reach. Repository calls are gated by the user's collaborator permission on
 `owner/repo`. The rest of the Gitea surface — reachable through the
 `gitea_request` escape hatch — is gated by **resource-type-aware authorization**
 (`authz.py`). Every call is classified by `(method, path)` and enforced against
 a type-specific rule. **Every decision fails closed**: a call that cannot be
 classified, or whose permission cannot be positively verified against Gitea, is
 denied and audited.
 | Resource type | Rule (service-PAT mode) |
 |---------------|--------------------------|
 | `repository` | Per-user collaborator permission on `owner/repo` (existing check). A repo path that cannot be parsed to `owner/repo` is denied. |
 | `org` | The signed-in user must be a **verified member** of the target org (checked against Gitea, fail closed). |
 | `user_owned` | A resource owned by a named user/org (`/users/{name}`, `/packages/{owner}`): allowed only when the owner is the caller, or the caller is a verified member of the owning org. |
 | `user_self` | Token-owner-scoped endpoints (`/user`, `/notifications`): **denied** — in service-PAT mode the data belongs to the bot, not the caller. |
 | `misc_global` | Instance-wide read-only utilities (markdown render, version, gitignore templates): reads allowed; writes denied. |
 | `admin` | **Default deny.** Allowed only when the operator opts in (`RAW_API_ALLOW_SENSITIVE=true`) **and** the signed-in user is a verified Gitea site administrator. |
 | `unknown` | Denied. |
 This gate runs *in addition to* the policy engine and the `WRITE_MODE` gate — a
 write call is denied unless write mode is on, policy allows it, and the
 resource-type rule passes. In pure-OAuth mode (no service PAT) the user's own
 token already scopes every call at Gitea, so the extra gate is unnecessary.
 Positive verification results (org membership, site-admin) are cached briefly
 and bounded; only successful checks are cached, so a transient failure never
 grants access.
 ## Full-API coverage: classified `gitea_request`
 `gitea_request` exposes the long tail of the Gitea API that the curated typed
 tools do not cover, safely:
 - **Deterministic read/write classifier.** `GET`/`HEAD` are reads; everything
  else is a write. A small, explicit override table may only *downgrade*
  provably side-effect-free render endpoints (markdown/markup) to reads — never
  the reverse — so a mutating call can never be misclassified as a read and slip
  past the `WRITE_MODE` gate.
 - **Known-path gate.** A request whose top path segment is not a recognized
  Gitea `/api/v1` route prefix is denied (fail closed): unknown paths are never
  passed straight through.
 - **Admin/credential denylist.** `/admin`, `*tokens*`, `*secrets*`, `*hooks*`,
  `*keys*`, `applications/oauth2`, and runner registration tokens are blocked for
  every method (including `GET`) and cannot be re-opened from `policy.yaml` —
  only `RAW_API_ALLOW_SENSITIVE=true` overrides them, and admin then still
  requires a verified site administrator (see above).

 """Resource-type-aware authorization (fail-closed).
 The public HTTP server runs in *service-PAT mode*: a privileged bot token makes
 the actual Gitea calls while a per-user OAuth identity decides what that user is
 allowed to reach. For repository-scoped calls the server verifies the user's
 collaborator permission on ``owner/repo``. This module closes the rest of the
 gap — the admin/user/org/misc surface that ``gitea_request`` can now reach — by
 classifying each call by *resource type* and enforcing a type-specific rule.
 Every decision fails closed: if a call cannot be classified, or a required
 permission cannot be positively verified against Gitea, it is denied and audited.
 Rules (enforced only in service-PAT mode; in pure-OAuth mode the user's own
 token already scopes every call at Gitea):
 * ``repository`` — per-user collaborator permission (handled by the server's
  existing repository check; not re-implemented here).
 * ``org`` — the signed-in user must be a verified member of the target org.
 * ``user_self`` — token-owner-scoped endpoints (``/user``, ``/notifications``).
  Denied in service-PAT mode: the data belongs to the bot, not the caller.
 * ``user_owned`` — a resource owned by a named user/org (``/users/{name}``,
  ``/packages/{owner}``). Allowed only when the owner is the caller, or the
  caller is a verified member of the owning org.
 * ``misc_global`` — instance-wide, read-only utility endpoints (markdown render,
  version, gitignore templates …). Reads allowed; writes fall to policy.
 * ``admin`` — default deny. Allowed only when the operator has opted in
  (``RAW_API_ALLOW_SENSITIVE``) *and* the signed-in user is a verified Gitea
  site administrator.
 * ``unknown`` — denied.

 -----------
 The local operator owns the Gitea Personal Access Token supplied via
 ``GITEA_TOKEN``; there is no per-user OAuth. At startup the adapter resolves the
 PAT owner (``GET /user``) and pins the request context to that single login.
 Because the caller *is* the token owner, the per-user repository-permission
 probe used by the public HTTP server is intentionally skipped — but the policy
 engine, ``WRITE_MODE`` gate, secret sanitization and the tamper-evident audit
 log all run exactly as they do on the server. The same tools (including

 """Generic raw Gitea REST dispatch tool (escape hatch).
 ``gitea_request`` exposes the long tail of the Gitea API that the curated, typed
 tools do not cover. A single tool surface would normally collapse the
 granularity of ``policy.yaml``, so this handler re-derives a coarse virtual tool
 name (``gitea_request:<METHOD>:<top-segment>``) and the target repository/path
 from each request and runs them back through the policy engine. That reuses the
 existing write-mode + write-whitelist enforcement and keeps per-method/per-repo
 policy control intact behind the single tool.
 Two layers of authorization apply:
 * The central dispatch gate in ``server.py`` allows/denies the registered
  ``gitea_request`` name and, in service-PAT mode, verifies the signed-in user's
  permission on the parsed repository.
 * This handler then authorizes the fine-grained virtual tool name and enforces a
  built-in admin/credential denylist that ``policy.yaml`` cannot re-open.
