- "The password minimum is enforced in usersAdmin.storePassword; the lagoon model validator's missing string min/max is deferred, because fixing it changes every model with string length rules"
- "The gate's name check covers every non-test file under modules/ and docs/ plus this phase's test files; older test files that name applications are outside the phase"
- "A hidden superuser's DELETE answers exactly what a missing id answers (200, deleted 0); the D-03 test asserts that equality instead of a 404"
patterns-established:
- "One rule, one named test: status, the en refusal text from UI-SPEC C8, and a byte-for-byte unchanged row"
- "Gate scripts list every required test by name and refuse skipped, zero-match or missing runs"

# Phase 19.6.1 Plan 03: Privilege rule tests, D-21 SPA tests and the phase gate Summary
**Every privilege rule of the Administrators and Roles screens now has a named test against the assembled admin on Postgres, including the concurrent last-superuser race on all five reducing paths. The D-21 trigger and record-lock behaviour is tested in Go, in vitest and at 1024px in Chromium. `scripts/check-phase19.6.1.sh --all` proves the phase fail-closed. The tests found two production bugs, each fixed in its own commit: a password under 4 characters was accepted, and bulk lifecycle actions changed only the first selected administrator.**
## Performance
- **Duration:** ~38 min
- **Started:** 2026-10-22T09:47:03Z
- **Completed:** 2026-10-22T10:24:41Z
- **Tasks:** 4
- **Files modified:** 23 (3761 insertions, 274 deletions)
## Accomplishments
- **Test env (tracer).** `administrators_harness_test.go` holds the screens harness:
- `newScreensEnv(t, extra...)` assembles the admin with any extra plugins.
- `seedAdmin` and `seedRole` insert unique rows and register cleanup.
- Also `login`, `isolateSuperusers`, `call`/`serve` (with `X-Requested-With` on writes), and `userRow`/`roleRow` (`row_to_json` snapshots).
- The pinger plugin's `acme_ping` action now has a switchable `Applies`, plus a token scope over `backend.manage_users`.
- `export_test.go` exposes `SuperuserLockKey`.
- **Save-path rules (Task 2):**
- D-03: superusers stay hidden from a delegate in the list, under search and filters, on GET, the hint partial, record actions, PUT and DELETE (a DELETE answers exactly as for a missing id), in bulk selections, and in both schemas. A superuser's scoped personal token is treated the same way; a `*` token is not.
- D-05: only a superuser may send the switch, true or false, on create or update.
- Pitfall 1: saving the SPA payload of an untouched superuser record keeps the flag.
- D-06/D-07: permission and role ceilings. A stored locked override is kept. A user-level deny is merged last and shuts the delegate out of the screen. An above-ceiling role the target already holds is kept.
- D-08: self-edit limits. D-11: password rules and unique identity. D-19: the delegate is outranked on all eleven write paths. D-20: own password.
- `TestRoleCeiling` covers `grantsCovered`.
- **Race and lifecycle (Task 3):**
- `TestAdministratorsLastSuperuser` has five literal subtests. In each, a test transaction holds `pg_advisory_xact_lock(SuperuserLockKey)` until `pg_locks` shows two ungranted advisory locks. Exactly one 2xx, one 403 with the last_superuser text, one superuser left, no 500 or deadlock. Stable across `-count=4`.
- `TestAdministratorsLastSuperuserConcurrent` runs ten unsynchronized rounds.
- Lifecycle and revocation tests (two-row bulk selections included).
- The seam: `TestActionExtensionBoot` (all refusals and the declared order) and `TestActionExtensionRun`.
- Roles: `TestRolesLifecycle` and `TestRolesPermissionCeiling`.
- `TestBackendScreensActivation`.
- **D-21 and the gate (Task 4):**
- Go: `TestFieldTriggerBoot`, `TestPermissionRecordLocks` (radio and checkbox), `TestRolesCodeDeclaredLocks`.
- SPA:
- `trigger.test.ts` (11 tests).
- FormView backstops: disable, absent controlling field, hide-tab removal with the banner line, and the live announcement.
- PermissionEditorField and formState: record-locked rows.
- PreviewView: hide.
- The 1024px browser footer test.
- The gate script and the filled validation map.
## Task Commits
1. **Task 1 (tracer): screens test env and the superuser flag rule.** `536ea8c` (test). Tracer gate: the `<verify>` was re-run end to end and passed before Task 2.
2. **Task 2: save-path rule tests.** `461cb21` (fix, deviation 1), `b684bb7` (test)
3. **Task 3: race, lifecycle, revocation, seam and roles.** `8324070` (fix, deviation 2), `1a56294` (test)
4. **Task 4: D-21 tests, gate, validation map.** `085179b` (test, Go), `4c61a18` (test, SPA), `7842aca` (chore, gate), `8f3d625` (docs, validation map and deferred items)
## Files Created/Modified
- `modules/cabana/administrators_harness_test.go`: the shared Postgres screens env (moved from `backend_screens_smoke_test.go` and extended).
- `modules/cabana/administrators_postgres_test.go`: the nine save-path rule tests.
- `modules/cabana/administrators_lifecycle_postgres_test.go`: the race helper and the lifecycle and revocation tests.
- `modules/cabana/backend_privileges_internal_test.go`: `TestRoleCeiling`.
- `modules/cabana/action_extensions_test.go`, `action_extensions_postgres_test.go`: the D-14 seam.
- `modules/cabana/roles_postgres_test.go`: Roles and code-declared locks.
- `modules/cabana/field_trigger_test.go`, `record_locks_test.go`: D-21 unit tests.
- `modules/cabana/backend_screens_test.go`: `TestBackendScreensActivation`.
- `modules/cabana/backend_users_admin.go`: the two fixes.
- `admin/tests/form/*.test.ts`, `admin/tests/browser/record-actions-wrap.test.ts`, `admin/vitest.browser.config.ts`: the SPA tests.
- `scripts/check-phase19.6.1.sh`: the gate.
## Decisions Made
- I reused the Plan 01 harness rather than building a second one. The file is now `administrators_harness_test.go`, as the plan names it. The existing `call(t, method, rel, token, body)` argument order stayed, so the four Plan 01 smokes run unchanged.
- The D-07 "above-ceiling role kept" case uses a holder whose override denies the extra grant. Without that the holder would outrank the delegate (D-19), and no save could reach the role check.
- "The override merged last" is shown through route access (a deny of `backend.manage_users` returns 403 on the list), because `/auth/me` does not expose permissions.
- The gate's docs stage checks non-test sources plus this phase's test files. Older lagoon and postcard tests name applications, and that is pre-existing.
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 1 - Bug] The Administrators form accepted a 3-character password**
- **Found during:** Task 2 (`TestAdministratorsPasswordAndIdentity/too_short` got 201)
- **Issue:** `FormRules` declares `min:4`, but `lagoon.Validate` (the model validator) collects string `min`/`max` tags and then skips them, so the rule never applied. D-11 was not enforced.
- **Fix:** `usersAdmin.storePassword` now refuses a typed password under `adminPasswordMinChars` (4) characters (counted with `utf8.RuneCountInString`). It answers 422 on `password` with the `min.string` text, next to the existing 72-byte check. The lagoon gap is logged in deferred-items.md.
- **Files modified:** modules/cabana/backend_users_admin.go
- **Verification:** the test passes with "at least 4 characters"; `go test -short ./...` is green.
- **Committed in:** `461cb21`
**2. [Rule 1 - Bug] Bulk activate, deactivate and restore changed only the first selected administrator**
- **Found during:** Task 3 (`TestAdministratorsLifecycle`: bulk deactivate reported `affected: 2`, but the second row stayed active)
- **Issue:** `actionDB` returned the `Unscoped()` instance of a NewDB session. GORM conditions accumulate on that instance, so the second `Where("id = ?")` update matched `id = A AND id = B` (no row) while still being counted. A bulk deactivate therefore left every row after the first active and signed in, which breaks D-10 and D-12 revocation.
- **Fix:** `actionDB` now ends with `.Session(&gorm.Session{})`, so every query starts fresh.
- **Files modified:** modules/cabana/backend_users_admin.go
- **Verification:** `TestAdministratorsLifecycle` checks stored rows after the bulk calls. `TestAdministratorsRevocation` now ends two sessions and two personal tokens in one bulk deactivate and one bulk delete. Plan 01's lifecycle smoke still passes.
- **Committed in:** `8324070`
**3. [Rule 3 - Blocking] The browser layout test needs the admin's CSS**
- **Found during:** Task 4.
- **Issue:** `vitest.browser.config.ts` had no Tailwind plugin, so a footer mounted with the real classes would have no layout.
- **Fix:** I added `tailwindcss()` to the browser config. The test imports `src/styles/main.css` and copies the footer classes from PreviewView.vue. The richeditor browser tests are unaffected.
- **Files modified:** admin/vitest.browser.config.ts (not in the plan's file list)
- **Committed in:** `4c61a18`
**4. Commit scope.** Commits use `(19.6.1-03)` as the orchestrator instructed: `test`, `chore` for the script, `docs` for the planning files. The two production fixes use `fix(cabana)`, as the plan requires. There are no co-author tags.
**5. Assertions adapted to built behaviour (no rule weakened).**
- A hidden superuser's DELETE returns the framework's "deleted 0" answer, identical to a missing id, so it reveals nothing. The test asserts that equality instead of a 404.
- Own overrides are refused through the record lock ("You cannot change this permission.") before the `self_privileged` check. The test asserts the 403 on `permissions` and an unchanged row.
- One TestRoleCeiling case (`*.manage` held covering `acme.manage`) was dropped: `granted` does not expand held leading wildcards. That is pre-existing behaviour, logged in deferred-items.md.
---
**Total deviations:** 3 auto-fixed (2 bugs, 1 blocking), plus 2 notes.
**Impact on plan:** The two fixes close real gaps in D-11 and D-10/D-12 on the server. There is no scope creep.
## TDD Gate Compliance
The tasks are marked `tdd="true"`, but this plan is the project's "unit tests last" plan: it tests behaviour Plans 01 and 02 built. So most tests passed on first run, and there are no `feat(19.6.1-03)` commits. Where a test failed because the code was wrong (deviations 1 and 2), the failing test came first and the fix went into its own `fix(cabana)` commit.
## Verification
- `go vet ./...`, `go test -short ./...`, `go -C examples/hello test ./...`: pass. These ran inside the gate's go stage and after each task.
- Docker-backed tests ran directly (the Docker socket was accessible):
- `go test ./modules/cabana ./modules/surf`: pass.
- The gate's docker stage passed: 21 Postgres rule and smoke tests by name, 10 SC-1 regression tests, and 162 surf tests.
- `npm --prefix admin run typecheck`: pass. `npm --prefix admin run test`: 94 files, 1461 tests pass. `npm --prefix admin run test:browser`: 2 files, 8 tests pass.
- `scripts/check-admin-openapi.sh --check` and `scripts/check-admin-dist.sh`: pass, and the dist is unchanged.
- `bash scripts/check-phase19.6.1.sh --all`: **exit 0**, "Phase 19.6.1 gate passed". PASS for self-test, go, admin, docs, sc1 and docker; no NOT RUN.
- SC-1: 17 commits since `88ec4df`; no phase commit touches commands.go, token_commands.go or account.go.
- Every acceptance grep of the four tasks prints the expected count.
## Issues Encountered
None blocking. Two out-of-scope findings are in deferred-items.md:
- lagoon's model validator skips string `min`/`max`, so for example an over-long `login` reaches Postgres as a 500 instead of a 422.
- `granted` does not expand a held leading wildcard.
## Known Stubs
None.
## Threat Flags
None. The two fixes tighten existing surface (T-19.6.1-07, T-19.6.1-11). T-19.6.1-24..27 are mitigated:
- every rule has a named test, and the gate requires each name;
- the race is forced on every path;
- `isolateSuperusers`, unique rows and cleanup keep tests apart, and there is no `t.Parallel`;
- the name check covers the phase's tests.
No package was added.
## User Setup Required
None.
## Next Phase Readiness
- Phase 19.6.1 is complete. Its last plan is done, and the gate is ready as input for `/msd-verify-work`.
- Manual UAT remains: the screens in a real browser session, as a superuser and as a limited administrator (VALIDATION manual-only row).
- Before the next release tag, it is worth looking at the lagoon string `min`/`max` gap (deferred-items.md).
