phase: 06-http-routing-auth-groups-and-rate-limiting
plan: 03
subsystem: auth
tags: [surf, wire, cors, body-limit, raw-group, openapi, route-table, house-middleware]

requires:
  - phase: 06-http-routing-auth-groups-and-rate-limiting
    provides: pact.Router verbs and name:param factories, inv_token + jwt.auth groups, throttle factory and five fonoteka buckets
provides:
  - Router.GroupRaw with sticky raw inheritance and registration-time house-envelope refusal
  - pact.HasHouseMiddleware collected only from Assemble/BuildRouter's plugin loop
  - Router.Routes() / RouteInfo and surf.RouteListCommand (route:list)
  - wire.WriteJSON, WriteOpaque500, Time (+00:00), TriBool, Slice
  - path-scoped CORS matching config/cors.php (JWT group: no headers; token group: *)
  - per-route http.MaxBytesReader body limits with operator-confirmed 128MiB production numbers
  - raw oauth group declared with zero handlers; inv.must-change-password house-tagged
  - committed OpenAPI document from ListGenres swag annotations, validated by openapi-typescript
affects: [06-05-tests, phase-08-oauth, phase-10-admin-spa]

tech-stack:
  added: []
  patterns:
    - HasHouseMiddleware is the only plugin-facing house-tag path; plugins never call Register*
    - Assemble = BuildRouter + compile so route:list inspects without serving
    - Laravel-style CORS globs (api/* matches nested segments), not Go path.Match
    - swag v1 Swagger 2 converted by a local swagger2openapi helper to OpenAPI 3 for openapi-typescript 7

key-decisions:

  - "Assemble split into BuildRouter + compile so route:list can read Routes() without serving"
  - "CORS path globs compile as Laravel * (nested segments), because Go path.Match would miss /api/v1/fonoteka/genres"
  - "Production body limits are 134217728/134217728 (128MiB binary), operator-confirmed 2026-09-19 from nginx 128M + php.ini 128M/128M (D-18, T-06-13)"
  - "swag v1 emits Swagger 2; a local swagger2openapi converter produces OpenAPI 3 for openapi-typescript 7.13.0"

patterns-established:
  - "Raw groups refuse house-tagged middleware at wrap()/Assemble time and recover with a bare 500"
  - "House vs ordinary middleware is a plugin capability split (Middlewares vs HouseMiddlewares), not a Register* call site"
  - "Non-raw routes wrap http.MaxBytesReader from http.body_limits.default_bytes; body.limit:N overrides innermost; raw routes stay uncapped at this layer"
  - "genre_controller writeJSON/writeOpaque500 are one-line delegations to wire"

# Phase 6 Plan 03: Raw groups, wire, CORS, and body-limit Summary

**Registration-time raw-group house-middleware refusal, route table + route:list, wire JSON helpers, path-scoped CORS, and operator-confirmed 128MiB body limits (134217728) with a committed OpenAPI document from ListGenres**

## Performance

- **Duration:** 20 min active execution (human-verify pause between Task 3 code and close-out not counted)
- **Started:** 2026-09-19T17:55:32Z
- **Completed:** 2026-09-19T18:57:39Z
- **Tasks:** 3 (Task 3 includes the production body-limit checkpoint)
- **Files modified:** 24

## Accomplishments

- `GroupRaw` plus sticky raw inheritance: a raw group cannot spawn a non-raw child. House-envelope names are declared only through `pact.HasHouseMiddleware`; `BuildRouter` registers them and `wrap()` fails boot with `surf: raw group cannot use house-envelope middleware %q (plugin %q)`. Raw panics write a bare 500; non-raw keep the house JSON body.
- `Router.Routes()` returns a defensive `[]RouteInfo` (method, pattern, plugin, middleware, raw). `surf.RouteListCommand` renders it; generated `main` registers `route:list` next to `serve`. Mutual-exclusivity of jwt.auth vs inv_token/inv.scope is asserted over the assembled table (closes T-06-02 / T-06-10).
- `wire.WriteJSON` matches genre_controller byte-for-byte (`SetEscapeHTML(false)`, trailing-newline trim). `wire.Time` marshals Carbon `+00:00` never `Z`; `TriBool` nulls when invalid; `Slice` never returns nil. `ListGenres` delegates and carries swag annotations; `docs/openapi.json` is committed and validated by openapi-typescript 7.13.0.
- Path-scoped CORS copies `config/cors.php` (`api/*`, `_user/api/*`, `_journal/api/*`, `_feedback/api/*`, `oauth/mcp/*`). JWT `/_fonoteka/api/v1/genres` emits no `Access-Control-Allow-Origin`; personal-token `/api/v1/fonoteka/genres` emits `*`.
- Body limits: non-raw routes wrap `http.MaxBytesReader` from `http.body_limits.default_bytes`; `body.limit:N` overrides innermost; raw routes are uncapped at this layer. Production values are operator-confirmed 2026-09-19: nginx `client_max_body_size=128M`, php.ini `post_max_size=128M` and `upload_max_filesize=128M` → **134217728 / 134217728** (128 × 1024 × 1024). D-18 / T-06-13 closed. No `INTERIM` remains in production yaml.
- `golem15.fonoteka` implements `HouseMiddlewares()` with `inv.must-change-password`. The oauth group is `GroupRaw("/", Use(), empty)` with zero handlers; Phase 8 attaches `throttle:fonoteka-oauth-token` / `throttle:fonoteka-oauth-register` per-route.

**Plan metadata:** (this commit)

## Files Created/Modified

- `pact/capabilities.go` — `GroupRaw` on Router; `HasHouseMiddleware`
- `surf/router.go` — raw flag, house-tagged registration, BuildRouter, per-route recoverBare/recoverJSON, body-limit wrap, path-scoped CORS
- `surf/routetable.go` — `RouteInfo` and `Routes()` defensive copy
- `surf/routelist_command.go` — `route:list` table command
- `surf/cors.go` — `CORSConfig`, Laravel glob compile, path-scoped middleware
- `surf/bodylimit.go` — `http.MaxBytesReader` default + `body.limit:N` override
- `wire/response.go` — WriteJSON, WriteOpaque500, Time, TriBool, Slice
- `internal/build/build.go` — generated main appends `surf.RouteListCommand`
- `plugins/golem15/fonoteka/plugin.go` — `HouseMiddlewares()`; `inv.must-change-password` moved out of `Middlewares()`
- `plugins/golem15/fonoteka/routes.go` — empty `GroupRaw` oauth landing spot
- `plugins/golem15/fonoteka/controllers/genre_controller.go` — wire delegation + swag comments
- `plugins/golem15/fonoteka/routes_cors_test.go` — CORS, house-capability, raw-refusal, route-table exclusivity on real plugins
- `config/http.yaml` — cors.php paths; body_limits 134217728/134217728 operator-confirmed 2026-09-19
- `scripts/check-openapi.sh` / `scripts/swagger2openapi.go` / `docs/openapi.json` — swag → OpenAPI 3 → openapi-typescript

## Decisions Made

- House-tagged middleware is a plugin capability (`HasHouseMiddleware`), never a `Register*` call from plugin code (D-16, T-06-11).
- `Assemble` is `BuildRouter` then `compile()`, so `route:list` inspects the table without serving.
- CORS `*` globs match nested path segments the way Laravel `api/*` does; Go `path.Match` would leave `/api/v1/fonoteka/genres` without CORS and fail Pitfall 10.
- Body-size numbers are not a guess: operator read production nginx + php.ini on 2026-09-19; both keys are 134217728 (D-18, T-06-13).
- swag v1.16.6 stays (STACK.md rejects swag v2 RC); a local converter bridges Swagger 2 → OpenAPI 3 for openapi-typescript 7.13.0. Phase 10 owns wiring types into the admin SPA.

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Laravel glob instead of Go path.Match for CORS paths**
- **Found during:** Task 3 (path-scoped CORS)
- **Issue:** The plan specified `path.Match("api/*", trimmedPath)`. Go's `path.Match` does not let `*` cross `/`, so `api/*` would not match `api/v1/fonoteka/genres` and the personal-token group would emit no CORS headers — failing Pitfall 10 and HTTP-09.
- **Fix:** `compileLaravelGlob` treats `*` as `.*` (Laravel `fnmatch` / `api/*` semantics) against the leading-slash-stripped path.
- **Files modified:** `surf/cors.go`, `surf/cors_test.go`
- **Verification:** `go test ./surf -run TestCORS`; fonoteka `TestCORSPathScopedOnAssembledRouter` (JWT empty ACAO, token `*`)
- **Committed in:** `30539b9` (Task 3)

**2. [Rule 3 - Blocking] Local swagger2openapi converter so openapi-typescript 7 can validate swag v1 output**
- **Found during:** Task 2 (check-openapi.sh)
- **Issue:** swag v1.16.6 emits Swagger 2.0 (`docs/swagger.json`). openapi-typescript 7.13.0 requires OpenAPI 3.x. STACK.md forbids swag v2 (RC only).
- **Fix:** `scripts/swagger2openapi.go` converts the swag JSON to OpenAPI 3; the script writes `docs/openapi.json` and deletes the intermediate swagger.json. No new dependency.
- **Files modified:** `scripts/swagger2openapi.go`, `scripts/check-openapi.sh`
- **Verification:** `bash scripts/check-openapi.sh` exits 0; `docs/openapi.json` contains `/_fonoteka/api/v1/genres`
- **Committed in:** `db51df6` (Task 2)

**Total deviations:** 2 auto-fixed (2 Rule 3 blocking)
**Impact on plan:** Both required for HTTP-08/HTTP-09 to be true. No scope creep; no extra libraries.

## Issues Encountered

None beyond the two auto-fixes. The human-verify checkpoint is planned flow, not an issue: operator reported all three production values as 128 MB on 2026-09-19.

## Checkpoint Resolution (D-18 / T-06-13)

Operator-confirmed 2026-09-19 from the production host:

| Source | Value |
|--------|-------|
| nginx `client_max_body_size` | 128M |
| php.ini `post_max_size` | 128M |
| php.ini `upload_max_filesize` | 128M |

Converted with binary megabytes (nginx `m` / PHP `M` = 1024×1024): `128 * 1024 * 1024 = 134217728`.

`fonoteka.go/config/http.yaml`:

- `http.body_limits.default_bytes: 134217728`
- `http.body_limits.upload_bytes: 134217728`

INTERIM comments replaced with the confirmation comment. Body-limit tests assert against config-loaded / fixture YAML values and were not changed.

Re-run:

- `go test ./surf -count=1 -run BodyLimit` (summercms.go) — pass
- `go test ./plugins/golem15/fonoteka/... -count=1 -short` (fonoteka.go) — pass

## Auth Gates

Task 3 `checkpoint:human-verify` for production body-size numbers. Operator confirmed; numbers applied; plan closed. Not a deviation.

## Known Stubs

None that block this plan. The oauth `GroupRaw` has zero handlers by design (Phase 8 owns the two POST routes). Empty jwt_locale / onboarding / public_invitation / public_share builders were already declared in 06-02.

## User Setup Required

None remaining. The production-host body-size read is done (2026-09-19).

## Next Phase Readiness

- Phase 8 can mount `/oauth/mcp/token` and register on the existing raw group without house envelope/error middleware.
- Phase 10 can consume `docs/openapi.json` (already valid TypeScript via openapi-typescript).
- 06-05 owns full coverage, the remaining route-table assertions, and `06-SECURITY-REVIEW.md`.
- No blockers.

## Self-Check: PASSED

- FOUND: surf/routetable.go, surf/routelist_command.go, surf/cors.go, surf/bodylimit.go, wire/response.go, pact/capabilities.go
- FOUND: fonoteka.go/config/http.yaml default_bytes=134217728 upload_bytes=134217728, zero INTERIM
- FOUND: fa7e6d1, 9ecf2d1, 30539b9 (summercms.go); db51df6, cdc324a, 73671a8 (fonoteka.go)
- `go test ./surf -count=1 -run BodyLimit` pass; `go test ./plugins/golem15/fonoteka/... -short` pass
