Release 0.9.0: admin user-management page + new-request notifications

Ships DOCS.md and the /docs route — a plain-prose translation of
SPEC.md for users, distinct from the binding spec. Originating need
was the admin-vs-owner role distinction on /admin/users (§6.1);
response is a single guide that covers the framework's user-facing
surfaces end-to-end (roles, proposing, branches, PRs, graduation,
notifications). Mirrors /philosophy: markdown file at repo root +
sibling backend loader + MarkdownPreview render. No schema migration.

+## 0.14.0 — 2026-05-28
+
+**Minor — no operator action required; new optional env var.** This
+release ships `DOCS.md` and the `/docs` route — a public-facing user
+guide that translates `SPEC.md` into plain prose for readers,
+proposers, and contributors. The originating need was the
+admin-vs-owner distinction on the `/admin/users` surface (the §6.1
+role separation was load-bearing but only documented in spec voice);
+the response was a single guide that covers the framework's user-
+facing surfaces end-to-end. Mirrors `/philosophy` end-to-end: a
+markdown file checked into the repo root, served by a sibling backend
+loader, rendered with `MarkdownPreview`. No schema migration. No
+required env-var changes. The new "Docs" header link sits alongside
+the persistent "About" link from §14.3 and is reachable by anonymous
+viewers per the same v0.3.0 anonymous-read contract.
+
+### Added
+
+- **`DOCS.md`** at the repo root — the user-facing guide. Covers
+  reading anonymously, signing in, proposing an RFC, super-drafts vs
+  active RFCs, the discussion-vs-contribution distinction (§10.10),
+  working on a branch (contribute mode, AI proposals, manual edits,
+  flags, branch visibility, contribute grants, hygiene), opening and
+  reviewing PRs, graduation (§13), withdrawal and reopening, the AI
+  participant (§6.6 / §6.7 / §18), notifications and watch states
+  (§15), and the full roles-and-permissions story (§6 in plain
+  prose: anonymous / contributor / admin / owner, per-RFC
+  owners + arbiters, per-branch contribute grants, the write-mute,
+  and the three structurally distinct "mutes"). Framework-neutral —
+  no deployment-specific names or corpus references; consistent with
+  `CLAUDE.md`'s separation-of-concerns rule.
+- **`backend/app/docs.py`** — sibling loader for `philosophy.py`.
+  Reads `DOCS.md` from the repo root with the same disk-first,
+  in-process-cached, `refresh()`-on-demand shape. Optional
+  `DOCS_PATH` env var points at an alternative source (e.g. a
+  meta-repo working-tree clone) for deployments that prefer that.
+- **`§17` endpoint** — `GET /api/docs` returns
+  `{ "body": "<DOCS.md verbatim>" }`. Anonymous-reachable, same
+  contract as `GET /api/philosophy`.
+- **`frontend/src/components/Docs.jsx`** — the `/docs` reading
+  surface. Mirrors `Philosophy.jsx`: chrome with Back / "USER GUIDE" /
+  Home affordances, body rendered through `MarkdownPreview`.
+
+### Changed
+
+- **`backend/app/api.py`** — imports `docs as docs_mod` alongside
+  `philosophy` in the relative-import block; registers the new
+  `GET /api/docs` handler immediately after `GET /api/philosophy`.
+- **`frontend/src/api.js`** — exports `getDocs()` alongside
+  `getPhilosophy()`. Same fetch shape, different endpoint path.
+- **`frontend/src/App.jsx`** — imports `Docs` alongside `Philosophy`,
+  registers the `/docs` route alongside `/philosophy`, adds the
+  persistent "Docs" header link alongside "About", and adds the
+  `DocsWithSidebar` chrome wrapper alongside `PhilosophyWithSidebar`.
+
+### Upgrade steps (from 0.13.0)
+
+- You **MUST** rebuild the frontend and restart the backend after
+  upgrading so the new `/docs` route, the new endpoint, and the new
+  loader are picked up. `frontend/package.json#version` and `VERSION`
+  both move to `0.14.0`. No schema migration; the new endpoint
+  serves a checked-in file.
+- You **MAY** set `DOCS_PATH` to an absolute path if your deployment
+  hosts `DOCS.md` outside the framework's repo (e.g. as a sync target
+  from a content repo). Unset is supported — the framework's
+  `DOCS.md` at the repo root is the default, mirroring how
+  `PHILOSOPHY_PATH` works for `/api/philosophy`.
+- You **MAY** customize `DOCS.md` for your deployment if you want
+  deployment-specific phrasing layered on top of the framework's
+  guide. The file is a regular markdown source; standard `vim`/`git`
+  edits suffice. Framework upgrades that ship a new `DOCS.md` will
+  show as a normal merge in your deployment-overlay layer.
+
+## 0.13.0 — 2026-05-28
+
+**Minor — schema migration required; new optional env vars.** This
+release ships the cookie / privacy consent surface (roadmap item #11,
+SPEC §14.5 / §14.6). Every viewer — authenticated and anonymous alike —
+now sees a non-modal bottom-of-page banner on first visit asking which
+categories of cookies they allow (essential / essential + analytics /
+essential + analytics + other). The choice persists in `localStorage`
+for anonymous viewers and in a new `cookie_consent` table for
+authenticated viewers, with server-side overriding local on sign-in.
+The framework also ships default `/privacy` and `/cookies` policy pages
+that deployments can layer their own policy URL on top of via two new
+optional env vars. No analytics SDK ships in this release — the
+consent infrastructure is wired so item #13 (v0.15.0) can read from
+`frontend/src/lib/consent.js` when the SDK lands.
+
+### Added
+
+- **Cookie consent banner** (`frontend/src/components/CookieConsentBanner.jsx`).
+  Non-modal, bottom of viewport. Three single-select choices with
+  inline descriptions. Visible until the user makes a choice; hides
+  thereafter. Reachable for revision via the settings surface.
+- **Consent helper** (`frontend/src/lib/consent.js`). Exports
+  `getConsent()`, `hasChosen()`, `onConsentChange(cb)`, `setConsent()`,
+  `hydrateFromServer()`, `clearLocal()`. Cross-tab sync via the
+  `storage` event. Item #13's analytics SDK reads consent here before
+  importing.
+- **Privacy and cookies policy pages**
+  (`frontend/src/pages/Privacy.jsx`, `frontend/src/pages/Cookies.jsx`).
+  Default minimal policies that describe the framework's stance and
+  list the cookies the framework sets. Deployments override via the
+  two new env vars below; the framework's stub always renders above
+  the link so the framework-level contract stays visible.
+- **"Privacy & cookies" tab** in `/settings/notifications` showing
+  the current consent choice, the recorded-at stamp, and a "Change"
+  button that re-opens the banner via a custom DOM event.
+- **`§17` endpoints** —
+  - `GET  /api/users/me/cookie-consent` — read the current consent
+    record.
+  - `PUT  /api/users/me/cookie-consent` — write a new consent record.
+    Upserts a single row per user, stamps `recorded_at` to now,
+    accepts `essential` for symmetry but always persists it as true.
+- **Schema migration** `013_cookie_consent.sql` — new
+  `cookie_consent` table keyed by `user_id`, three flags
+  (`essential`, `analytics`, `other_cookies`), and `recorded_at`.
+  (Renumbered from `012_*` during driver integration because v0.7.0
+  also added a `012_otc.sql` migration that landed in the integration
+  order before this one.)
+- **SPEC `§14.5` Cookie / privacy consent** — settles the banner
+  shape, the three-category single-select, the storage shape (local
+  for anon, server row for authenticated), the precedence rule on
+  sign-in, and the `consent.js` helper surface for downstream
+  callers including item #13.
+- **SPEC `§14.6` Privacy and cookies policy pages** — settles the
+  `/privacy` and `/cookies` routes, the framework's stub content, and
+  the `VITE_PRIVACY_POLICY_URL` / `VITE_COOKIES_POLICY_URL` override
+  shape.
+- **SPEC `§5`** — names the `cookie_consent` table in the canonical
+  app-tables list.
+- **SPEC `§17`** — lists the two new cookie-consent endpoints.
+- **SPEC `§19.2`** — surfaces four candidates: policy content via
+  content-repo file vs env var, GPC / DNT headers, multi-language
+  consent text, and the item #13 analytics-SDK gating dependency.
+
+### Changed
+
+- **`frontend/.env.example`** — documents the two new optional env
+  vars `VITE_PRIVACY_POLICY_URL` and `VITE_COOKIES_POLICY_URL`. Unset
+  is supported; defaults render the framework's stub.
+- **`backend/app/api_notifications.py`** — module docstring grew two
+  endpoint lines; the new endpoints sit alongside the existing
+  `/api/users/me/*` neighbors.
+- **`frontend/src/App.jsx`** — registers `/privacy` and `/cookies`
+  routes (anonymous-reachable), wires `<CookieConsentBanner>` into
+  the global chrome, and listens for a `rfc-app:cookie-consent-reopen`
+  custom event to re-open the banner from the settings surface.
+
+### Upgrade steps (from 0.7.0)
+
+- You **MUST** rebuild the frontend and restart the backend after
+  upgrading. `frontend/package.json#version` and `VERSION` both move
+  to `0.13.0` and the build embeds the new env-var contract.
+- You **MUST** apply schema migration `013_cookie_consent.sql`. The
+  migration creates a single new table keyed by `user_id` with three
+  flag columns and a `recorded_at` stamp. The framework runs
+  migrations automatically at process start; no manual step is
+  required beyond restarting the backend so the migration runner
+  picks the file up.
+- You **MAY** set `VITE_PRIVACY_POLICY_URL` to an http(s) URL that
+  points at your deployment's full privacy policy. The framework's
+  `/privacy` page renders its built-in stub above a link to the
+  configured URL. Unset is supported — the stub is sufficient for a
+  default-config deployment.
+- You **MAY** set `VITE_COOKIES_POLICY_URL` to an http(s) URL that
+  points at your deployment's full cookies policy. Same shape as the
+  privacy URL.
+- You **MAY** announce the new consent banner to your users. Existing
+  authenticated users will see the banner on their next visit
+  (because their `cookie_consent` row does not yet exist); their
+  current sessions remain valid.
+
+## 0.10.0 — 2026-05-28
+
+**Minor — schema migration required; new auth path is additive.**
+This release lands user-set passcodes after OTC (roadmap item #8,
+SPEC §6.2). After a successful one-time-code sign-in, the user can
+set a passcode (4–20 characters) and use email + passcode for
+subsequent sign-ins. OTC remains the structural fallback: a
+forgotten passcode is recovered by requesting a fresh code, and
+five consecutive failed passcode verifies lock the passcode path
+for 15 minutes (HTTP 423) while leaving the OTC path open. The
+`/login` surface now consults a new `GET /auth/passcode/check`
+endpoint after the email step to decide whether to render a
+passcode input or an OTC code input; an "Use a code instead" link
+on the passcode step lets the user fall back to OTC manually. The
+`/settings/notifications` page grew a new "Sign-in" tab where the
+user can set, change, or remove their passcode.
+
+### Upgrade steps (from 0.8.0)
+
+1. **MUST** restart the backend so migration `015_passcode.sql`
+   runs. The migration adds four nullable columns to the `users`
+   table: `passcode_hash`, `passcode_set_at`,
+   `passcode_failed_attempts` (default 0), `passcode_locked_until`.
+   Existing rows pass through with `passcode_hash = NULL`, which
+   the runtime treats as "no passcode set" — every existing user
+   continues to sign in via OTC unchanged, and can opt into a
+   passcode from the new settings tab at any time.
+2. **MUST** rebuild the frontend so the v0.10.0 `/login` flow and
+   the new settings tab ship. `frontend/package.json#version` and
+   `VERSION` both move to `0.10.0`.
+3. **SHOULD** announce the new sign-in option to users. Wording
+   suggestion: "You can now set a passcode for faster sign-in.
+   We'll keep emailing one-time codes as a fallback — if you
+   forget your passcode, just request a code as usual."
+4. **MAY** leave the §6.2 default lockout shape (5 attempts,
+   15-minute window) unchanged. v0.10.0 does not expose env
+   tunables for these; raising or lowering them lives in §19.2
+   as a candidate.
+
+### Added
+
+- **`POST /auth/passcode/set`** — authenticated. Body `{passcode}`.
+  Validates length (4–20) and refuses obvious patterns from a small
+  denylist (`0000`, `1234`, `aaaa`, `password`, etc.). bcrypt-hashes
+  the passcode and writes `users.passcode_hash` plus
+  `users.passcode_set_at`. Clears any active lockout and the
+  failure counter (a user setting a fresh passcode is implicitly
+  re-authenticating). Replaces any prior passcode.
+- **`DELETE /auth/passcode`** — authenticated. Clears the passcode
+  hash and the set-at stamp; the user is back to OTC-only.
+- **`POST /auth/passcode/verify`** — unauthenticated. Body
+  `{email, passcode}`. Returns HTTP 200 + minimal user payload on
+  success; HTTP 423 with `locked_until` when the account is in the
+  lockout window; HTTP 400 for every other failure (the
+  wrong-passcode and unknown-email modes both collapse to 400 so
+  the response does not enumerate account state).
+- **`GET /auth/passcode/check`** — unauthenticated. Query param
+  `email`. Returns `{has_passcode: boolean}`. The Login.jsx flow
+  consults this after the email step to decide whether to render a
+  passcode input or fall back to OTC. The response carries only
+  the boolean; lockout state, the hash, and the `passcode_set_at`
+  stamp are not leaked. An unknown email and a known-without-
+  passcode email both return `false`, so the endpoint is
+  account-enumeration-safe.
+- **Schema migration** `015_passcode.sql` — four ALTER TABLE ADD
+  COLUMN statements on the `users` table:
+  - `passcode_hash TEXT` (nullable) — the bcrypt hash. NULL means
+    "no passcode set".
+  - `passcode_set_at TEXT` (nullable) — ISO-8601 timestamp.
+  - `passcode_failed_attempts INTEGER NOT NULL DEFAULT 0` —
+    consecutive failure counter since last success.
+  - `passcode_locked_until TEXT` (nullable) — lockout window
+    expiry; verify refuses with HTTP 423 while populated and
+    in the future.
+- **`backend/app/passcode.py`** — the passcode state machine:
+  validation (length + denylist), bcrypt hashing, set/clear,
+  status check, and the verify path with lockout management.
+- **`frontend/src/components/Login.jsx`** — extended to a five-step
+  surface: email → passcode-or-code → optional post-OTC
+  passcode-offer → optional set-passcode. The "Use a code instead"
+  link on the passcode step re-dispatches an OTC and switches to
+  the code step. A 423 from passcode verify auto-falls back to OTC
+  with a visible status message.
+- **"Sign-in" tab** in `/settings/notifications` — shows
+  passcode-set status, the recorded `passcode_set_at` stamp when
+  set, and Set / Change / Remove buttons. Mirrors the §14.5
+  "Privacy & cookies" tab pattern.
+- **SPEC `§6` / `§14.1` / `§17` / `§19.2`** corrections per §19.3
+  rule 2:
+  - §6 names the three current auth paths (OTC, passcode-with-OTC-
+    fallback, OAuth-fallback-during-migration).
+  - §14.1 documents the stepped `/login` surface and the passcode
+    check endpoint.
+  - §17 lists the four new `/auth/passcode/*` endpoints.
+  - §19.2 surfaces four new candidates (passcode policy tunables
+    via env, per-IP rate-limit on `/auth/passcode/verify`,
+    passcode-change "old passcode" challenge, passkey/WebAuthn);
+    the "device-trust 30d" entry's passcode cross-ref is updated;
+    the "first-OTC profile capture" entry's roadmap cross-ref is
+    updated.
+
+### Changed
+
+- **`backend/app/main.py`** — registers the four new
+  `/auth/passcode/*` routes on the existing oauth router, alongside
+  the v0.7.0 `/auth/otc/*` routes.
+- **`backend/app/api.py`** — `/api/auth/me` payload now includes
+  `has_passcode` (boolean) and `passcode_set_at` (string or null)
+  so the settings surface can render the Set / Change / Remove
+  affordances without a second round trip.
+- **`frontend/src/api.js`** — adds `checkPasscode`, `verifyPasscode`,
+  `setPasscode`, `clearPasscode` helpers, neighboring the v0.7.0
+  `requestOtc` / `verifyOtc` block.
+- **`frontend/src/components/NotificationSettings.jsx`** — adds the
+  `SignInSection` component between `MutesSection` and
+  `PrivacyCookiesSection`.
+
+### Tests
+
+- **`backend/tests/test_passcode_vertical.py`** — 17 new tests
+  cover: set requires session; check returns false for unknown and
+  for set-less users; check returns true after set without leaking
+  other fields; happy-path OTC → set → verify roundtrip; wrong
+  passcode increments the counter without locking; five consecutive
+  failures lock with 423 and persist `passcode_locked_until`;
+  lockout expires and the next attempt clears the counter; the OTC
+  path is unaffected by passcode lockout; clear wipes the hash and
+  set-at; setting a new passcode replaces the prior one and resets
+  the lockout; `passcode_set_at` updates on every set; validation
+  refuses too-short passcodes and denylist patterns; `/api/auth/me`
+  carries `has_passcode` and `passcode_set_at` correctly.
+
+### Environment variables
+
+None new. The existing `SECRET_KEY` continues to sign session
+cookies; passcode hashing reuses the bcrypt dependency added in
+v0.7.0. The lockout shape (5 attempts, 15 minutes) and the length
+range (4–20) are hard-coded in `backend/app/passcode.py`. See
+§19.2 for the env-tunable candidate.
+
+## 0.9.0 — 2026-05-28
+
+**Minor — no schema migration; reuses v0.8.0 columns and existing
+SMTP.** This release ships the admin user-management surface at
+`/admin/users` and the new-beta-request notifications that feed
+it (roadmap item #7, SPEC §6.1 / §15 / §17). The two halves
+compose: admins receive an inbox + email signal the moment a
+pending user submits the v0.8.0 capture form; clicking through
+lands on the page where they Grant or Revoke access.
+
+The page consumes the v0.8.0 schema columns
+(`permission_state`, `first_name`, `last_name`,
+`beta_request_reason`, `permission_decided_by`,
+`permission_decided_at`) without adding new ones — migration
+slot 016 stays reserved for a future release. The single new
+write endpoint, `POST /api/admin/users/<id>/permission`,
+replaces v0.8.0's documented manual `UPDATE users SET
+permission_state='granted'` gesture with an audited UI flip.
+
+Admin notifications ride the existing §15 chokepoint — the
+`new_beta_request` event_kind is added to the enum with
+category `admin-actionable`, fan-out is to every owner / admin
+minus the requester themselves, and the §15.4 email dispatch
+only reaches recipients whose `email_admin_actionable` toggle
+is on (the default for owners + admins). The event is the
+framework's first non-RFC-scoped notification — `rfc_slug` is
+NULL and the email deep-link points `/admin/users` instead of
+`/rfc/<slug>`.
+
+Decision on `/admin/allowlist`: the surface stays as a
+sibling sub-tab, not folded into `/admin/users`. The two have
+different keys (allowlist by email pre-sign-up, user list by
+user_id post-sign-up) and a union row would be confusing
+rather than clarifying. The allowlist's fast-path-bypass role
+from v0.8.0 is unchanged; retiring the table outright is
+deferred to a later session (see §19.2).
+
+### Upgrade steps (from 0.10.0)
+
+1. **MAY** rebuild the frontend. The build is the same shape
+   as v0.10.0; the lockfile pins to `0.9.0` so `npm install`
+   in `frontend/` updates it cleanly. No new env vars on the
+   frontend; the existing `VITE_APP_NAME` requirement carries
+   over.
+2. **MAY** restart the backend. No schema migration runs in
+   this release — every v0.9.0 column is from
+   `014_beta_access.sql` (v0.8.0). Restart only if you want
+   the new endpoints registered in this version's binary.
+3. **SHOULD** verify SMTP can reach the deployment's admin
+   inbox before the first pending user submits the capture
+   form. v0.9.0 reuses the v0.7.0 SMTP configuration
+   (`SMTP_HOST`, `SMTP_PORT`, `SMTP_USER`, `SMTP_PASSWORD`,
+   `SMTP_STARTTLS`, `EMAIL_FROM`, `EMAIL_FROM_NAME`); a
+   misconfigured deployment will still write the inbox row,
+   but the admin won't hear about it through email. No new
+   env var is required — the framework reuses the existing
+   admin-user list (role IN ('owner', 'admin')) as the
+   notification recipients.
+4. **SHOULD** announce the surface to existing admins. Wording
+   suggestion: "There's now a Users tab in /admin where you can
+   Grant or Revoke beta access — and you'll get an email +
+   inbox row when a fresh request lands. The manual SQL gesture
+   from v0.8.0 still works but is no longer the documented
+   path."
+5. **MAY** drain the existing pending queue through the new UI.
+   If your deployment carried pending users through the v0.8.0
+   manual-UPDATE window, the Pending bucket on `/admin/users`
+   surfaces all of them with their captured profile. Granting
+   from the UI stamps `permission_decided_by` /
+   `permission_decided_at`, which any prior manual UPDATE
+   gestures may have left NULL (no harm done — the v0.8.0
+   contract didn't require those stamps).
+
+### Added
+
+- **`POST /api/admin/users/<id>/permission`** — body
+  `{state: 'pending'|'granted'|'revoked'}`. Flips the column,
+  stamps `permission_decided_by` + `permission_decided_at`,
+  and writes a `permission_events` row with event_kind in
+  `{permission_granted, permission_revoked,
+  permission_repended}`. Refuses 422 on self-flip (symmetric
+  to `set_mute` / `set_role` self-action refusals) and 422
+  on invalid state. Returns `{ok, permission_state, changed}`
+  where `changed=false` indicates a no-op (the requested
+  state already matched).
+- **Widened `GET /api/admin/users` response** carrying
+  `permission_state`, `first_name`, `last_name`,
+  `beta_request_reason`, `created_at`,
+  `permission_decided_at`, plus joined
+  `permission_decided_by_login` /
+  `permission_decided_by_display`. Sort order surfaces
+  `pending` rows first (the admin queue), then `granted`,
+  then `revoked`; within a bucket, owners precede admins
+  precede contributors, with recency as the tiebreaker.
+- **`new_beta_request` event_kind** in the §15.1 enum. Fired
+  by `notify.fan_out_new_beta_request` from the first
+  successful `POST /api/auth/me/beta-request` (re-submits
+  from the same pending user don't re-fire — the row's
+  first-time-complete check guards against carpet-bombing).
+  Recipients: every owner + admin minus the requester
+  themselves. Category: `admin-actionable`. Deep-link:
+  `/admin/users`. Actor: the requester per §15.9.
+- **`/admin/users` page enhancements** in `Admin.jsx`. The
+  Users tab gains a state filter chip row (All / Pending /
+  Granted / Revoked with counts), a Grant / Revoke control
+  column, a Permission state badge, and an expandable
+  "why they want access" row beneath each pending user.
+  Sign-up timestamp surfaces in a new column.
+- **`frontend/src/api.js#setUserPermission`** — client for
+  the new endpoint, neighboring `setUserMute` and
+  `setUserRole`.
+- **`/beta-pending` copy update** in `BetaPending.jsx`. The
+  "your request is in review" page now honestly references
+  the admin-email signal v0.9.0 ships and admits the
+  framework does not commit to an SLA — turnaround depends
+  on operator availability, and the deployment operator is
+  the right person to ask if a wait runs long. No
+  deployment-specific text is baked in; per-deployment copy
+  lives in §13 of the deployment's repo, not in the
+  framework.
+- **`backend/tests/test_admin_users_vertical.py`** — 10 new
+  tests covering: a beta-request submission fans
+  notifications to every admin + owner (and not to the
+  requester or to contributors); the requester's profile
+  fields land in the notification payload; re-submitting
+  the capture form does not re-fan; the `admin-actionable`
+  category mapping is wired; the `/api/admin/users`
+  listing carries the v0.8.0 columns with `pending` rows
+  sorted first; the permission-flip endpoint promotes
+  pending → granted with the right audit shape; the
+  endpoint promotes granted → revoked; the endpoint
+  refuses self-flip with 422; the endpoint refuses
+  non-admin callers with 403 and anonymous callers with
+  401; the endpoint refuses invalid states with 422; a
+  state-already-matches flip returns `changed=false`
+  without writing an audit row.
+
+### Changed
+
+- **`backend/app/api.py`** — the `POST /api/auth/me/beta-request`
+  handler now calls `notify.fan_out_new_beta_request` after the
+  capture UPDATE lands, gated on the row not previously having
+  all three profile fields populated (so re-submits don't
+  re-fan).
+- **`backend/app/api_admin.py`** — the `list_users` query joins
+  against `users d ON d.id = u.permission_decided_by` for the
+  deciding-admin handle. The new `set_permission` endpoint
+  lives alongside `set_role` / `set_mute`.
+- **`backend/app/notify.py`** — adds
+  `CATEGORY_ADMIN_ACTIONABLE`, the `fan_out_new_beta_request`
+  helper, and the `new_beta_request` arm in `render_summary`.
+- **`backend/app/email.py`** — the `_EVENT_TO_CATEGORY` map
+  carries `new_beta_request → admin-actionable`, and
+  `_deep_link` routes framework-scoped admin signals to
+  `/admin/users` instead of `/rfc/<slug>`.
+- **`frontend/src/components/Admin.jsx`** — the `UsersTab`
+  component is rewritten with state filter chips, a per-row
+  `UserRow` + `PermissionCell` decomposition, and a
+  `useMemo`-cached counts table. The pending-row reason
+  blockquote renders as a secondary `<tr>` beneath the user
+  row when present.
+- **`frontend/src/components/BetaPending.jsx`** — pending-state
+  copy revised to reference the admin email signal honestly.
+- **`frontend/src/App.css`** — new admin-chip / permission-badge
+  / user-row-reason rules.
+- **`SPEC.md`** §6 opening, §15.1 event-kinds enum, §17 admin
+  endpoints, §19.2 candidates list — per §19.3 rule-2.
+- **`VERSION`** → `0.9.0`. `frontend/package.json#version` and
+  the lockfile mirror.
+
+### Environment variables
+
+None new. The release reuses the v0.7.0 SMTP configuration
+(`SMTP_HOST`, `SMTP_PORT`, `SMTP_USER`, `SMTP_PASSWORD`,
+`SMTP_STARTTLS`, `EMAIL_FROM`, `EMAIL_FROM_NAME`,
+`EMAIL_ENABLED`, `EMAIL_BUNDLE_THRESHOLD`) and the existing
+admin-user list (role IN ('owner', 'admin')) as the
+notification recipients. A deployment whose SMTP is misconfigured
+will still see the inbox rows; only the email channel is muted.
+
+### Deferred to later releases
+
+- **Grant / revoke notification to the user** — symmetric
+  signal: when an admin grants or revokes access, fire a
+  `personal-direct` notification (event_kind
+  `permission_change_affecting_me`, already in the §15.1
+  enum) so the affected user sees the state change in
+  their inbox and email. v0.9.0 audits the gesture in
+  `permission_events` but does not yet escape the
+  app-internal log to the user. See §19.2.
+- **Decline-with-reason on revoke** — the current Revoke
+  gesture takes only a confirmation; a follow-up release
+  may capture a free-text reason in
+  `permission_events.details`. See §19.2.
+- **Allowlist deprecation** — the `/admin/allowlist` sub-tab
+  stays in place in v0.9.0 (the two surfaces have different
+  keys and a union row would be confusing). Retiring the
+  table outright is deferred to a session that can re-read
+  the post-v0.9.0 operator experience and decide whether
+  the fast-path-bypass role is still pulling weight. See
+  §19.2.
+
+## 0.8.0 — 2026-05-28
+
+**Minor — schema migration required; admission semantics shift.**
+This release replaces the v0.3.0 / v0.7.0 `allowed_emails` admission
+gate with an admin-grant flow (roadmap item #6, SPEC §6.1 / §6.2 /
+§14.1 / §17). Anyone with a valid email can sign in via the v0.7.0
+OTC flow; the OTC request endpoint no longer consults the
+allowlist. A fresh user lands in `permission_state='pending'` until
+an admin grants access. The first-OTC sign-in captures first name,
+last name, and a free-text "why I should be included in the beta"
+via a new `POST /api/auth/me/beta-request` endpoint; the captured
+fields populate the same `users` row alongside the OAuth-era
+columns.
+
+A pending user has the same read access an anonymous viewer has —
+the catalog, RFC bodies, the philosophy page, and every public
+conversation are reachable. Every write-shaped endpoint
+(`auth.require_contributor` floor) refuses pending users with 403.
+The frontend renders a thin "Your beta access request is in
+review" banner on every page and re-purposes the v0.3.0
+`/beta-pending` page as the post-capture landing surface.
+
+Grandfathered behavior: every `users` row at migration time
+carries `permission_state='granted'` via the column default, so
+existing contributors are unaffected. The OAuth fallback at
+`/auth/callback` still consults the v0.3.0 allowlist (legacy
+path); the OTC flow does not.
+
+The `allowed_emails` table stays in the schema as a fast-path
+bypass — the v0.3.0 admin UI continues to manage it, but the OTC
+request handler no longer reads it. v0.9.0 (roadmap item #7) is
+expected to ship the admin user-management page that replaces the
+allowlist surface entirely; until then, admin grants are done by
+direct DB `UPDATE`.
+
+### Upgrade steps (from 0.13.0)
+
+1. **MUST** restart the backend so migration `014_beta_access.sql`
+   runs. The migration adds `permission_state` (default `'granted'`,
+   so existing rows pass through unaffected), `first_name`,
+   `last_name`, `beta_request_reason`, `permission_decided_by`,
+   and `permission_decided_at` to the `users` table, plus an index
+   on `permission_state` for the pending queue. The migration is
+   ALTER-TABLE-based (no table rebuild) — every foreign key and
+   existing row passes through untouched.
+2. **MUST** rebuild the frontend. The `Login.jsx` surface now
+   runs a conditional third step (the capture form) on fresh OTC
+   sign-ins; `BetaPending.jsx` carries the new "your request is
+   in review" copy; `App.jsx` renders a thin pending-access
+   banner. The build embeds the new `/api/auth/me/beta-request`
+   client call.
+3. **SHOULD** announce the new admission flow to existing users.
+   Wording suggestion: "We've replaced our email-allowlist gate
+   with an admin-review flow. Existing users are unaffected;
+   new visitors sign in with their email, tell us a bit about
+   themselves, and an admin reviews their request before
+   discussion and contribution unlock." Existing sessions
+   remain valid.
+4. **SHOULD** plan the admin grant mechanism. v0.8.0 does not
+   ship a UI for the grant — v0.9.0 (roadmap item #7) will. For
+   the v0.8.0 window, an admin grants access via direct DB
+   gesture:
+   ```sql
+   UPDATE users
+      SET permission_state = 'granted',
+          permission_decided_by = <admin_user_id>,
+          permission_decided_at = datetime('now')
+    WHERE email = '<approved>';
+   ```
+   The pending queue lives in `SELECT * FROM users WHERE
+   permission_state = 'pending' ORDER BY created_at`.
+5. **MUST** decide whether to drain the `allowed_emails` table.
+   The OTC request handler no longer consults it; populated
+   rows are inert at the request surface. Three operator
+   choices, all valid:
+   * **Leave as-is** (the framework's default behavior — the
+     v0.3.0 admin UI continues to work, the rows stay as a
+     fast-path bypass record). Recommended if you anticipate
+     v0.9.0's user-management page folding the allowlist UI
+     into its surface.
+   * **Drain via the existing admin UI** (`/admin/allowlist`)
+     — one row at a time, no data loss elsewhere.
+   * **Bulk-drain via DB** — `DELETE FROM allowed_emails;`
+     drops every row; the table stays.
+6. **MAY** announce write access individually to grandfathered
+   users you want to keep at `'granted'`. The default-`'granted'`
+   migration means no action is required for them; this step
+   exists only if you want to send a "you're still in" message.
+
+### Added
+
+- **`backend/migrations/014_beta_access.sql`** — adds
+  `permission_state` (CHECK in `('pending', 'granted', 'revoked')`,
+  default `'granted'`), `first_name`, `last_name`,
+  `beta_request_reason`, `permission_decided_by` (FK to users,
+  ON DELETE SET NULL), `permission_decided_at` to the `users`
+  table. Plus `idx_users_permission_state` for the pending
+  queue.
+- **`POST /api/auth/me/beta-request`** — body
+  `{first_name, last_name, beta_request_reason}` (all required;
+  bounds 120 / 120 / 4000). Writes the fields to the signed-in
+  user's row and leaves `permission_state='pending'`. Refuses
+  HTTP 409 for already-granted / revoked users; refuses HTTP
+  401 for anonymous callers.
+- **`needs_profile` flag** on the `/auth/otc/verify` response.
+  `true` iff the user is `permission_state='pending'` AND
+  carries no profile fields yet (a fresh OTC sign-in). The
+  Login.jsx surface uses the flag to gate the capture step.
+- **`permission_state` field** on the `/api/auth/me` response,
+  plus `first_name`, `last_name`, `beta_request_reason`, and
+  the same `needs_profile` flag.
+- **First-OTC profile capture step** in `Login.jsx`. Third
+  step in the sign-in surface, gated by the verify response's
+  `needs_profile` flag.
+- **`/beta-pending` repurpose** in `BetaPending.jsx`. The
+  page now reads as "your request is in review" when the
+  viewer is pending; the v0.3.0 "private beta" framing
+  remains as the anonymous-viewer fallback.
+- **Thin pending-access banner** at the top of every page
+  for `permission_state='pending'` viewers (other than
+  `/beta-pending` itself).
+- **SPEC `§6` opening / `§6.1` / `§6.2` / `§14.1` / `§17` /
+  `§19.2`** corrections per §19.3 rule-2 — the admission
+  shift, the orthogonality of permission_state vs role / muted
+  / notification-mutes, the new endpoints, and the
+  newly-surfaced §19.2 candidates (admin user-management page,
+  allowlist deprecation, admin notification on new request).
+- **`backend/tests/test_beta_access_vertical.py`** — 9 new
+  tests covering: a fresh OTC user lands pending with empty
+  profile; the capture endpoint populates the fields and
+  keeps state pending; the capture endpoint refuses
+  anonymous / granted / revoked callers; a pending user is
+  refused write endpoints; an admin grant promotes pending →
+  granted; a grandfathered user is unaffected by the
+  migration; the OTC request endpoint accepts any email
+  regardless of allowlist state; the `allowed_emails` table
+  is still present in the schema.
+
+### Changed
+
+- **`backend/app/auth.py#require_contributor`** widens its
+  gate to refuse `permission_state != 'granted'` with HTTP
+  403. The §6.1 contributor capabilities (propose, branch,
+  PR, chat, claim) all funnel through this dependency, so
+  the widening covers them transitively. `SessionUser` now
+  carries `permission_state` (default `'granted'` for the
+  dataclass-default fallback path).
+- **`backend/app/otc.py#request_code`** drops the allowlist
+  check from the OTC request flow. The `RequestOutcome`
+  shape loses the `'allowlist'` reason (replaced by
+  `'sent'` / `'cooldown'` / `'invalid'`).
+- **`backend/app/otc.py#provision_or_link_user`** sets
+  `permission_state='pending'` explicitly on a fresh row.
+  Grandfathered (link-by-email) users pass through with
+  their existing column value.
+- **`backend/app/auth.py#provision_user`** (OAuth fallback)
+  now sets `permission_state='granted'` explicitly on a
+  fresh row. The OAuth callback still consults the
+  `is_allowed_sign_in` allowlist check (the legacy fallback
+  path retains its v0.3.0 admission shape during the OAuth
+  migration window).
+- **`backend/tests/test_otc_vertical.py`** — the
+  `test_otc_request_silently_drops_when_email_not_on_allowlist`
+  test (asserted the v0.7.0 allowlist gate) is replaced by
+  `test_otc_request_admits_emails_regardless_of_allowlist_population`
+  which asserts the v0.8.0 open-request contract. The
+  on-list test stays as a regression net for the
+  rate-limit / outbound-buffer plumbing.
+- **`SPEC.md`** §6 opening, §6.1, §6.2, §14.1, §17, §19.2
+  per §19.3 rule-2.
+- **`VERSION`** → `0.8.0`. `frontend/package.json#version` and
+  the lockfile mirror.
+
+### Deferred to later releases
+
+- **Admin user-management page** at `/admin/users` (item #7,
+  v0.9.0) — replaces the manual DB `UPDATE` gesture.
+- **Allowlist UI deprecation** (also v0.9.0) — once the
+  admin user-management page lands, the `/admin/allowlist`
+  surface and the `allowed_emails` table both retire.
+- **Admin email notification on new beta request** (item #7
+  again, v0.9.0).
+- **Revoke gesture in the UI** — the `permission_state='revoked'`
+  state is wired in the schema and the auth gate; v0.9.0 ships
+  the admin UI that flips the column.
+
+## 0.7.0 — 2026-05-28
+
+**Minor — schema migration required; new auth path is additive.**
+This release lands email + one-time-code sign-in (roadmap item #5,
+SPEC §6.2) as the primary human-auth gesture. Users sign in by
+typing their email, receiving a six-digit code via email, and
+entering it. The Gitea OAuth callback (`/auth/callback`) remains
+functional during migration — the new UI no longer points at it
+primarily, but a "Sign in with Gitea (fallback)" link survives on
+the new login surface so users with active OAuth sessions or older
+invite paths still have a way in. A future release retires the
+OAuth path entirely once every active user has signed in at least
+once via OTC.
+
+The migration path for existing users: first OTC sign-in matches by
+`users.email` (case-insensitive) to the OAuth-era row and reuses
+that row's `id` and `gitea_id`. New users provisioned via OTC carry
+`gitea_id = NULL` and `gitea_login = NULL`. The `gitea_id` linker
+remains the canonical handle for grandfathered users; `email`
+becomes the identity key for everything provisioned after v0.7.0.
+
+The Gitea **bot** user + token are still required (server-side git
+operations — repo reads, PR creation — still flow through it). Only
+the operator-facing sign-in surface moves.
+
+### Upgrade steps (from 0.6.0)
+
+1. **MUST** restart the backend so migration `012_otc.sql` runs.
+   The migration rebuilds the `users` table (SQLite cannot ALTER
+   COLUMN); existing rows pass through unchanged, but the new
+   schema relaxes `gitea_id` / `gitea_login` to nullable (with
+   partial unique indexes that ignore NULL) and adds a partial
+   unique index on `email`. A new `otc_codes` table is created.
+2. **MUST** confirm the SMTP overlay is set (`SMTP_HOST`,
+   `SMTP_PORT`, `SMTP_USER`, `SMTP_PASSWORD`, `SMTP_STARTTLS`,
+   `EMAIL_FROM`, `EMAIL_FROM_NAME`). The OHM overlay already
+   carries these as of v0.5.0; deployments without them fall back
+   to logging the code to stdout (dev-only path — production
+   visitors will not receive their codes).
+3. **SHOULD** announce the new email-based sign-in to existing
+   users. Wording suggestion: "You can now sign in by entering
+   your email and a one-time code we'll send you. Your old
+   account is linked automatically the first time you sign in."
+4. **MAY** keep the existing OAuth callback as a fallback path.
+   The new login UI surfaces a small "Sign in with Gitea
+   (fallback)" link beneath the primary email/code form; a
+   deployment that prefers to hide it can override the Login
+   component in a future framework release that exposes the link
+   behind a feature flag. For v0.7.0, the link is hard-coded.
+
+### New environment variables (all optional with defaults)
+
+- `OTC_TTL_MINUTES` (default `10`) — how long a one-time code is
+  valid after issuance. Re-requesting invalidates the prior code
+  immediately regardless of TTL.
+- `OTC_REQUEST_COOLDOWN_SECONDS` (default `60`) — per-email cooldown
+  between successive `/auth/otc/request` calls. The endpoint returns
+  HTTP 429 when the cooldown blocks a request (the loud-failure
+  shape; the abuse path is visible rather than swallowed).
+
+No new secrets are required. The existing `SECRET_KEY` continues to
+sign session cookies; OTC codes are bcrypt-hashed at rest using a
+per-row salt the library generates.
+
+### Added
+
+- **`POST /auth/otc/request`** — body `{email}`. Generates a six-digit
+  code, stores its bcrypt hash with an expiry, and dispatches a plain
+  text email via the existing SMTP layer. Returns HTTP 200 (`{ok:true}`)
+  uniformly so allowlist state is not leaked. Returns HTTP 429 when
+  the per-email cooldown blocks the request.
+- **`POST /auth/otc/verify`** — body `{email, code}`. Validates the
+  bcrypt hash against the most-recent unconsumed non-expired row, marks
+  the row consumed, provisions or links the `users` row by email, and
+  stores the session cookie. Returns HTTP 200 on success, HTTP 400 on
+  any failure (expired, consumed, wrong, unknown).
+- **`backend/migrations/012_otc.sql`** — creates `otc_codes` and
+  rebuilds `users` with nullable `gitea_id` / `gitea_login` plus a
+  partial unique index on `email`.
+- **`backend/app/otc.py`** — the OTC request/verify state machine and
+  the `provision_or_link_user` linker.
+- **`backend/app/email_otc.py`** — outbound OTC mail composition. Reuses
+  the SMTP plumbing from `email.py` (`EmailConfig.from_env()`) and the
+  test buffer (`_SENT`) but writes its own envelope (no unsubscribe
+  footer, no quiet-hours hold — OTC mail carries a credential and
+  ignores notification preferences).
+- **`frontend/src/components/Login.jsx`** — two-step sign-in surface
+  at `/login`. Step 1: enter email → request code. Step 2: enter
+  six-digit code → verify. Cmd/Ctrl+Enter on the code field submits.
+  The previous header "Sign in" link and the `Welcome` component's
+  inline link now route to `/login` instead of jumping straight to
+  the Gitea OAuth dance.
+- **SPEC `§6.1` / `§6.2` / `§14.1` / `§17` / `§19.2`** corrections per
+  §19.3 rule-2 — see below.
+- **`backend/tests/test_otc_vertical.py`** — 11 new tests covering
+  the happy path, expired/consumed/wrong codes, the per-email rate
+  limit (and its per-email isolation), the allowlist gate, the
+  migration link to OAuth-era users, fresh provisioning, and the
+  prior-code-invalidation behavior on re-request.
+
+### Changed
+
+- **`backend/app/auth.py#current_user`** — coerces NULL `gitea_id` and
+  NULL `gitea_login` to `0` / `""` so the `SessionUser` shape stays
+  stable for OTC-only users. The DB remains the source of truth for
+  "is this user OAuth-linked" (`gitea_id IS NOT NULL`).
+- **`backend/requirements.txt`** — adds `bcrypt>=4.2` for OTC code
+  hashing. Pure-Python wheels are available on every platform the
+  deployment matrix targets; `pip install -r backend/requirements.txt`
+  picks it up.
+- **`frontend/src/App.jsx`** — adds the `/login` route and replaces
+  the header "Sign in" `<a href="/auth/login">` with `<Link to="/login">`.
+  The `Welcome` component's inline sign-in link follows suit.
+- **`frontend/src/components/Landing.jsx`** — the `/welcome` page's
+  primary action moves from "Sign in with Gitea" to "Sign in" pointing
+  at `/login`.
+
+### Deferred to later releases
+
+Per the v0.7.0 scope discipline (the foundation for items #6, #8, #9,
+#10), several adjacent capabilities are intentionally not in this
+release and surface as §19.2 candidates:
+
+- **First-OTC profile capture** (first name, last name, "why") — item
+  #6, expected v0.8.0.
+- **Open beta-access request flow** replacing the allowlist gate —
+  also item #6, v0.8.0.
+- **Passcodes** (a long-term reauth token alternative) — item #8,
+  expected v0.10.0.
+- **Device-trust 30-day skip** — item #9, expected v0.11.0.
+- **Cloudflare Turnstile** on `/auth/otc/request` — item #10,
+  expected v0.12.0.
+- **Removing the Gitea OAuth `/auth/callback` route entirely** — a
+  later release after every active user has signed in via OTC.

+# Using the RFC app
+
+This is the user-facing guide to the Wiggleverse RFC framework — how to
+read what's here, propose a new RFC, contribute to one that already
+exists, and understand who is allowed to do what.
+
+This guide describes the framework. Individual deployments brand and
+configure themselves independently — the name in the header and the
+corpus the RFCs are about belong to the deployment, not to this
+document.
+
+For the *why* of the framework, read the [philosophy](/philosophy).
+For the binding technical contract, see `SPEC.md` in the repository.
+
+---
+
+## Reading without signing in
+
+You can read the catalog and every public RFC without an account.
+Anonymous visitors can:
+
+- Browse the catalog of super-drafts and active RFCs.
+- Open any RFC and read its canonical body.
+- Read any public branch — its diff and its chat thread.
+- Read any pull request — its diff, its conversation, its review
+  comments.
+- Read the discussion that has accumulated on an RFC's main view.
+
+Reading is open by design. The framework's claim is that the *argument
+behind a definition* is the evidence that the definition was earned,
+and an argument that disappears behind a sign-in wall stops carrying
+that evidence.
+
+What you cannot do without an account: chat, propose a new RFC,
+create a branch, open a PR, drop a flag, or post on a discussion
+thread. Every write affordance is replaced with a sign-in prompt.
+
+---
+
+## Signing in
+
+While the framework is in private beta, only invited email addresses
+can complete sign-in. If your email is on the allowlist, the
+"Sign in" button in the header completes the flow and lands you on
+the catalog with full read and write access. If your email is not on
+the allowlist, you'll be sent to a short "pending" page explaining
+the gate.
+
+Once you have an account, you're a **contributor** by default — the
+role that grants every write affordance the app exposes, scoped by
+the per-RFC and per-branch rules described below.
+
+---
+
+## Proposing a new RFC
+
+A new RFC begins as a proposal. The "+ Propose new RFC" button at
+the bottom of the catalog opens a small modal that collects four
+things:
+
+- **Title.** The word, concept, or topic this RFC would define.
+- **Slug.** A kebab-cased identifier derived from the title. It is
+  the entry's stable handle from this moment until it graduates;
+  collisions with existing entries or open proposals are caught
+  inline.
+- **Pitch.** One or two paragraphs answering *why this RFC is
+  needed*. This becomes the body of the entry.
+- **Tags.** Optional. The AI suggests tags from the pitch; you can
+  accept, dismiss, or type your own.
+
+Submitting the modal does one concrete thing: it opens a pull
+request against the framework's meta repository, adding one new
+file under `rfcs/`. There is no other Git artifact and no other
+side-effect. You are returned to the **pending-idea view** for the
+new proposal.
+
+A pending idea is publicly readable but not yet a super-draft. The
+catalog surfaces it in a "Pending ideas" disclosure at the bottom
+of the list. A conversation can accumulate on the pending-idea view
+before it is admitted — contributors can argue, in public, about
+whether the entry belongs in the catalog at all.
+
+Three outcomes are possible:
+
+- **Merge.** An admin or owner merges the proposal PR. The entry
+  becomes a super-draft and graduates from the "Pending ideas"
+  section into the main catalog. Any conversation that accumulated
+  on the pending-idea view migrates with it.
+- **Decline.** An admin or owner declines, attaching a written
+  comment. You see the comment on your next visit, along with a
+  one-click affordance to revise and re-propose.
+- **Withdraw.** You can withdraw your own proposal at any time. The
+  entry will not appear in any default view; the conversation that
+  accumulated stays attached to the closed PR as historical record.
+
+You are automatically the first owner of any RFC you propose. The
+claim flow described under [Roles & permissions](#roles--permissions)
+is for *other* contributors to add themselves as owners later, not
+for the proposer.
+
+---
+
+## What a super-draft is
+
+A super-draft is an entry that has been admitted to the catalog but
+does not yet have its own dedicated repository. Most of the
+argument that shapes a definition happens here. The framework
+assumes — and the philosophy explicitly invites — that many
+super-drafts will not survive the argument, and that is fine. The
+entries that do survive earn their place in the catalog by being
+defensible in public.
+
+Opening a super-draft from the catalog gives you the same surface
+an active RFC uses:
+
+- The canonical body in the centre, read-only by default.
+- A chat thread on the right where the public conversation lives.
+- A breadcrumb dropdown listing any in-flight edit branches and
+  any open body-edit PRs against this entry.
+- A "Start Contributing" affordance that cuts a fresh edit branch
+  and lands you in contribute mode.
+
+Edits to a super-draft body propagate through pull requests against
+the meta repository — there is no dedicated RFC repository yet.
+
+---
+
+## What an active RFC is
+
+An active RFC is an entry that has been **graduated**. It has its
+own dedicated repository, an integer `RFC-NNNN` identifier, and a
+canonical body file (`RFC.md`) inside that repository. The catalog
+distinguishes super-drafts and active RFCs at a glance.
+
+Opening an active RFC gives you:
+
+- `main` — the canonical body, always read-only. Changes to `main`
+  arrive exclusively through pull requests.
+- A breadcrumb listing every open branch and pull request on this
+  RFC.
+- A per-branch chat thread on the right. Each branch has its own
+  conversation, including `main` itself.
+- A "Start Contributing" affordance: on `main` it cuts a new branch
+  and lands you on it in contribute mode; on any other branch you
+  already have push access to, it flips that branch into
+  contribute mode.
+
+---
+
+## Discussion vs contribution
+
+The framework draws an explicit distinction between two surfaces
+that other tools tend to conflate:
+
+- **Discussion** is what the RFC is *for*. The chat thread on an
+  RFC's main view is the place for "what about this part?" or
+  "have we considered…?" questions that don't yet warrant proposing
+  a specific edit. Posting on a discussion thread does not create
+  any Git artifact; the conversation lives in the app database.
+- **Contribution** is how an RFC *changes*. Editing the canonical
+  body requires opening a branch and, eventually, a pull request.
+  The pull request is the place a specific proposed change is
+  reviewed and merged.
+
+Reading both surfaces is open to anonymous visitors. Posting on
+either requires a contributor account.
+
+---
+
+## Working on a branch
+
+Contribute mode flips one branch into edit-enabled. The centre
+column splits: a markdown source pane on the left, a live-rendered
+preview on the right. Fenced `mermaid` blocks render as diagrams in
+the preview.
+
+Two kinds of edits accumulate on a branch:
+
+- **AI-proposed changes.** You ask the AI a question or request a
+  revision in the branch's chat. When the AI proposes a concrete
+  edit, that edit appears as a *change card* in a panel below the
+  chat — not yet applied to the document. You can **accept**,
+  **decline**, or **edit before accepting**. Accepting produces
+  one commit on the branch with the original text, the proposed
+  text, and the AI's reason recorded in the commit body.
+- **Manual edits.** Typing directly into the source pane buffers
+  locally and flushes as a single commit on an idle window, a
+  branch switch, or an explicit "Save now" button. Manual edits
+  also appear as change cards in the same panel — same evidence
+  shape, different author.
+
+Every accepted change is one commit. The framework does not
+support squash-merges or fixup-style cleanups: the per-change
+commit granularity is the framework's evidence unit, and
+collapsing it would erase what was earned.
+
+### Discuss mode vs contribute mode
+
+A branch defaults to discuss mode — read-only, with chat enabled.
+AI proposals still appear in chat, but they are *buffered* rather
+than applied; a single CTA invites you to flip the branch into
+contribute mode if you want to act on them. The toggle is an
+*intent* affordance, not a permission one. If you don't have push
+access to the branch, the toggle is disabled with a sign-in or
+request-access path.
+
+`main` is special: contribute mode is never available there. The
+"Start Contributing" button on `main` always cuts a new branch.
+
+### Flags
+
+Anywhere you can read, you can drop a flag. A flag is the
+lightweight "I'm pointing at this, it's a problem" gesture — a
+single short declarative statement anchored to a passage. Creating
+a flag requires a contributor account but does not require push
+access to the branch: any signed-in contributor who can read a
+passage can point at it and say it's wrong.
+
+Flags don't block PR merges by design — making them a merge gate
+would re-create the failure mode where contributors hastily "resolve"
+threads to unblock a button. Flags are prominent on PR headers but
+non-blocking.
+
+### Branch visibility
+
+A new branch is publicly readable by default. The branch creator
+can flip a branch to private, in which case only the creator, any
+explicit grantees, and the RFC's per-RFC owners and arbiters can
+read it. Owners and arbiters can flip it back.
+
+**Opening a PR makes the branch fully public.** If your branch is
+currently private, the "Open PR" affordance asks you to confirm
+this before submitting. There is no concept of a private PR — the
+framework's evidence claim depends on the argument being readable.
+
+### Who can push to a branch
+
+Every branch has one of three contribute modes:
+
+- **`just-me`** (default) — only the branch creator can push.
+- **`specific`** — only the branch creator and explicitly granted
+  contributors can push.
+- **`any-contributor`** — any signed-in contributor can push.
+
+The branch creator and the RFC's per-RFC owners and arbiters can
+change this setting at any time.
+
+### Branch hygiene
+
+A branch with no associated PR auto-closes after 30 days of
+inactivity. A closed branch is deleted from the Git host 60 days
+later. Closed branches remain in the catalog under a "show closed"
+filter — closing is a state, not a censorship event. The chat
+attached to a closed or deleted branch is preserved as historical
+record.
+
+Owners and arbiters can *pin* a branch to disable the auto-close
+timer if the work is paused but legitimately ongoing.
+
+---
+
+## Opening and reviewing a pull request
+
+A pull request is the deliberate "ready for review" gesture for
+work that has accumulated on a branch. The "Open PR" affordance is
+available on any branch with at least one commit ahead of `main`.
+
+The PR creation modal collects two AI-drafted fields, both editable
+before submit:
+
+- **Title.** A one-line description of the change, in spec voice.
+- **Description.** Two to four sentences pulling from the branch
+  chat, written for an arbiter.
+
+There is no reviewer picker. The RFC's arbiters are the implicit
+reviewer set.
+
+### The PR review page
+
+The review page shows the diff, the branch's compressed chat
+(messages that produced accepted changes are expanded, the rest is
+behind a "Show full conversation" toggle), and the review-comment
+surface inline below the chat.
+
+Review comments are not a separate concept from chat — they live in
+the same thread, anchored to a range in the diff. The framework's
+claim is that the disagreement an arbiter raises about a proposed
+change is the same *kind* of thing as the disagreement that
+produced the proposed change in the first place, and the two should
+share a surface.
+
+Each PR records a per-user seen-cursor. New diff hunks and new
+conversation messages since your last visit render with a subtle
+accent. The cursor advances on view; you do not have to mark
+anything as read.
+
+### Merging a PR
+
+Per-RFC owners and arbiters can merge; app-wide admins and owners
+also retain this capability. The merge produces a no-fast-forward
+commit on `main`, preserving every per-acceptance commit as an
+individually reachable node in `main`'s history.
+
+Merge is hard-blocked **only** by Git-level conflicts with `main`.
+Open review threads, pending change-cards, unresolved chat threads,
+and open flags do not block merge by design.
+
+### Conflicts with main
+
+A conflict surfaces on the PR page as a read-only banner. A "Start
+resolution branch" affordance cuts a fresh branch off `main`'s
+current tip, replays the work into it (asking the AI to resolve
+unambiguous conflicts, surfacing the rest for you), and opens a new
+PR. The original PR auto-closes when the resolution PR merges.
+
+Fixup commits on the existing branch are not supported. Per-change
+commit granularity is the framework's evidence unit; admitting
+"fix merge conflict with main" commits would dilute it.
+
+---
+
+## Graduation: super-draft → active RFC
+
+Graduation is the moment a super-draft becomes a canonical entry
+in the catalog. It is initiated by an app-wide admin, an app-wide
+owner, or one of the RFC's per-RFC owners or arbiters from the
+super-draft's page.
+
+Two preconditions block the action:
+
+- **The super-draft must have at least one owner.** The proposer
+  is automatically the first owner; if they have stepped away, any
+  contributor can use the "Claim ownership" affordance to add
+  themselves.
+- **No open body-edit PRs against the super-draft's entry.** An
+  open body-edit PR would attempt to re-introduce a body to a
+  frontmatter-only entry after graduation runs. Merge or withdraw
+  them first.
+
+When the dialog confirms, the framework runs a transactional
+sequence: create a fresh Git repository for the RFC, seed it with
+the super-draft's body as `RFC.md`, update the meta-repo entry to
+`state: active` with the integer ID and the new repository's URL,
+auto-merge that update. If any step fails partway, the sequence
+rolls back — the half-created repository is deleted and the
+unmerged update is abandoned. The dialog shows each step in flight
+and tells you exactly what happened.
+
+The chat thread on the super-draft moves to the new repository's
+`main` chat at graduation. Edit-branch chats from the super-draft
+phase stay attached to their original branches on the meta repo
+and surface from the new RFC view under a "Pre-graduation history"
+section.
+
+Graduation is not reversible. The path forward from an active RFC
+is withdrawal, not back to super-draft.
+
+---
+
+## Withdrawing and reopening
+
+An active RFC or a super-draft can be withdrawn by the proposer
+(for a super-draft they proposed) or by an admin or owner. A
+withdrawn entry stays in the catalog as a historical record but is
+hidden from default views. The entry is filterable back in.
+
+An admin or owner can reopen a withdrawn entry back into the
+super-draft state. The history is preserved across the transition.
+
+---
+
+## AI in the chat
+
+The chat on every RFC, super-draft, branch, and PR has an AI
+participant by default. The framework treats the AI as one voice
+among many in a public argument — not an oracle, and not a
+co-author whose name lands on commits.
+
+You invoke the AI by writing into the chat composer and submitting.
+Each message can pick a model from the picker (the option list is
+configurable per RFC). The AI responds in the chat; when its
+response includes a concrete change to the document, that change
+appears as a card you can accept, decline, or edit.
+
+When you accept an AI's proposed change, the commit's
+`On-behalf-of:` trailer names *you*, not the AI. The AI's authorship
+survives only as evidence — the original proposal in the commit body
+and the message that produced it in the chat record. The framework
+is explicit about this: AI participation produces evidence; it does
+not produce authorship.
+
+Two configuration knobs scope AI participation per RFC:
+
+- **Which models are available.** The meta-repo entry's frontmatter
+  carries an optional `models:` list. Absent means the RFC inherits
+  whatever models the deployment is provisioned to run. An empty
+  list (`models: []`) opts the RFC out of AI entirely — every AI
+  surface is absent rather than disabled-but-present.
+- **Whose credentials pay.** By default the deployment operator's
+  API credentials cover AI calls on every RFC. A `funder:`
+  frontmatter field can name a single contributor whose registered
+  credentials pay for AI calls on this RFC instead. The named
+  contributor must explicitly consent from their settings page;
+  either side can revoke at any time.
+
+Per-RFC AI configuration is edited through the meta-repo PR flow
+that governs the rest of the entry's frontmatter — by the RFC's
+per-RFC owners and arbiters, or by app-wide admins or owners.
+
+---
+
+## Notifications
+
+The framework's public-async work model produces signals that
+shouldn't all reach you the same way. Five surfaces compose:
+
+- **In-app inbox.** The durable triage surface. One mental space
+  across every RFC you have any relationship to, with per-RFC and
+  per-category filters. Reachable from the inbox icon in the
+  header.
+- **Badges.** Ambient pull-ins. A single integer beside the inbox
+  icon (count of unread notifications). A small binary dot on
+  individual catalog rows for watched RFCs with unseen activity.
+  No per-row counts and no per-section counts.
+- **Toasts.** Transient mid-session signals. Used only for your own
+  actions completing, and for events arriving on the view you're
+  currently looking at.
+- **Email.** The single channel that escapes the app. Opt-in per
+  category, conservative defaults. One-click unsubscribe per
+  category.
+- **Digest.** Aggregation for activity on watched RFCs you haven't
+  triaged through any other channel.
+
+### Watch states
+
+Every RFC has one of three implicit relationship states for you:
+
+- **Watching.** You receive structural signals for the RFC.
+- **Following.** You receive only churn-grade signals (new
+  commits, new chat messages on threads you didn't participate
+  in). This is a lighter relationship than watching.
+- **Muted.** You receive no signals for the RFC. The mute is
+  per-RFC and self-imposed; it does not affect what others see
+  or what reaches you on *other* RFCs.
+
+Watch states transition automatically based on your participation,
+with explicit overrides available from each RFC's header and from
+the notification settings page.
+
+### Email categories
+
+Four categories with distinct defaults:
+
+- **Personal-direct events** — default on. Signals where you are
+  the named subject. The contract is that when your name is on the
+  action, the framework reaches out of band.
+- **Watched-RFC structural events** — default off. PR opened on a
+  watched RFC, PR merged, graduation, withdrawal. Inbox and badges
+  carry these by default; the email toggle is opt-in.
+- **Watched-RFC churn** — permanently off, by design. Per-commit
+  and per-message email is intentionally not offered. The digest
+  aggregates this activity weekly.
+- **Admin-actionable events** — default on for admins and owners,
+  unused for contributors.
+
+### Quiet hours
+
+You can set a daily window during which email notifications are
+held. Messages held during the window are released at window end —
+bundled into a single "Activity while you were away" email if a
+threshold accumulated, otherwise sent individually.
+
+---
+
+## Roles & permissions
+
+Authorization in this framework is owned by the app itself, not by
+the Git host. The Git host sees only a single bot account — every
+commit, every PR, every merge passes through it on a user's behalf
+— and the *app* decides which users are authorized to ask the bot
+to do which things.
+
+### The four app-wide roles
+
+Each role is a strict superset of the one below it.
+
+1. **Anonymous.** Anyone who has not signed in. Can read public
+   RFCs, public branches, and public PRs; cannot chat, propose,
+   create branches, or open PRs.
+
+2. **Contributor.** The default role for any authenticated
+   account. Adds everything anonymous can do, plus: propose new
+   RFCs, create branches on any RFC repository, open PRs from
+   branches they have push access to, post on chat anywhere they
+   can read, claim ownership of unclaimed super-drafts.
+
+3. **Admin.** Adds the ability to act on any RFC, anywhere in the
+   framework. Concretely: merge any PR on any RFC, graduate any
+   super-draft, set branch visibility on anyone's behalf, withdraw
+   or reopen any entry, write-mute or restore any contributor,
+   grant or revoke the **admin** role.
+
+4. **Owner.** Adds two capabilities admin does not have: grant or
+   revoke the **owner** role itself, and disable an account
+   entirely. The framework names a single "owner zero" at
+   bootstrap.
+
+The practical difference between admin and owner is narrow but
+load-bearing: admin is the operational tier — it does the day-to-
+day moderation and stewardship work; owner is the tier that
+controls the admin tier. Disabling an account and creating other
+owners are owner-only because they affect the framework's chain of
+authority itself.
+
+The app refuses to let the last owner demote themselves silently —
+losing the last owner would leave nobody able to grant the role
+back. Role changes are recorded in an append-only `permission_events`
+log; an admin's own admin/users page shows the log of who promoted,
+demoted, or muted whom.
+
+### Per-RFC delegated authority
+
+The four roles above are framework-wide. Within an individual RFC,
+the meta-repo entry's frontmatter names two additional groups:
+
+- **`owners:`** — contributors elevated for this RFC. They can
+  grant push access on any branch in the RFC, merge any PR on the
+  RFC, change branch visibility, and withdraw the RFC.
+- **`arbiters:`** — contributors with merge authority for this RFC.
+  Functionally similar to per-RFC owners for merge decisions; the
+  distinction matters in some configuration paths.
+
+Per-RFC owners and arbiters are **not** app-wide admins. Their
+elevated powers are scoped strictly to the RFC named in the
+frontmatter. This is what lets the framework distribute work
+without putting one person on the hook for every action.
+
+The proposer of an RFC is automatically the first per-RFC owner.
+Additional per-RFC owners are added through a "Claim ownership"
+PR against the meta repository; app-wide admins or owners merge
+it.
+
+### Per-branch contribute grants
+
+Within an RFC, the branch creator and the RFC's per-RFC owners
+and arbiters can grant push access to specific contributors on a
+specific branch — `specific` contribute mode, described under
+"Working on a branch."
+
+### The write-mute
+
+An app-wide admin or owner can **mute** a contributor. A muted
+account retains read access and keeps its existing branches, but
+cannot create new branches, open new PRs, propose new RFCs, or
+post chat. This is a moderation tool, distinct from removing the
+account; restoring is the reverse gesture.
+
+The write-mute applies only to contributors. Promoting a user to
+admin or owner is the way to remove a user's write-restriction in
+the structural sense; the write-mute is for *retaining* an account
+while removing its ability to act.
+
+Every mute and every restore is recorded in `permission_events`.
+
+### Three different "mutes"
+
+The word "mute" appears in three structurally distinct places.
+They share a word and nothing else.
+
+- **Write-mute.** Admin-imposed. Removes a contributor's ability
+  to post or push. Described above.
+- **Per-RFC notification mute.** Self-imposed. Sets your watch
+  state on a specific RFC to *muted* — you stop receiving signals
+  for that RFC, in inbox, badges, and email. Does not affect what
+  others see.
+- **Per-user notification mute.** Self-imposed. Suppresses
+  notifications produced by a specific other user, anywhere in
+  the framework. Notification-volume only — it does not affect
+  what you can read.
+
+A write-muted contributor continues to receive notifications
+normally, so they can triage what they can't act on, and so a
+restore lands cleanly.
+
+### Audit trail
+
+Every gesture that changes app state — role changes, mutes,
+graduations, withdrawals, grant changes — is recorded in
+append-only logs the app maintains. Git commit history is for
+code archaeology; the app's audit log is the accountability
+record. An admin's page surfaces both `permission_events` (the
+role/mute log) and `actions` (the state-transition log) for
+review.

+Authentication has three paths, in the order a visitor encounters
+them:
+
+1. **Email + one-time code (OTC).** The v0.7.0 primary path: a
+   visitor enters their email address, receives a six-digit code via
+   SMTP, and exchanges the code for a session. Used by every visitor
+   on first sign-in, and as the fallback for the other two paths.
+2. **Email + passcode (with OTC fallback).** Added in v0.10.0
+   (roadmap item #8). After a successful OTC sign-in, the visitor
+   may set a user-chosen passcode (4–20 characters, bcrypt-hashed at
+   rest) and use email + passcode on subsequent sign-ins. Five
+   consecutive failed verifies lock the passcode path for 15 minutes
+   (HTTP 423); during the lockout the user falls back to OTC. The
+   OTC path is unaffected by the passcode lockout, so a forgotten
+   passcode is recovered by requesting a fresh OTC — there is no
+   separate "forgot passcode" flow. The user can remove the passcode
+   at any time from the §6.2 sign-in settings tab, returning to
+   OTC-only.
+3. **Gitea OAuth fallback (migration only).** The v0.1 OAuth
+   callback remains functional during the v0.7.0 window, with a
+   small "Sign in with Gitea (fallback)" link on `/login` so users
+   with active OAuth sessions or older invite paths still have a
+   way in. Scheduled for removal in a future release per §19.2.
+
+`users.gitea_id` is preserved on existing rows so a grandfathered
+user signing in via any of the three paths resolves to the same row.
+`users.email` is the identity key for everything provisioned after
+v0.7.0; `users.gitea_id` is the grandfathering linker (nullable,
+partial-unique). The Gitea bot user + token are still required for
+server-side git operations (repo reads, PR creation); only the
+operator-facing sign-in surface moved.
+
+Admission, as of v0.8.0, is by admin grant. v0.7.0 carried the
+v0.3.0 `allowed_emails` table forward as the admission gate at the
+OTC request surface — emails not on the list got a silent drop.
+v0.8.0 (roadmap item #6) reverses that: any valid email receives an
+OTC, the fresh `users` row lands in `permission_state='pending'`,
+and an admin grant flips the column to `'granted'` before write
+endpoints accept the user. The capture-fields step (first name,
+last name, free-text "why I should be included in the beta") feeds
+the admin's triage queue. The `allowed_emails` table stays in the
+schema as a fast-path bypass — the v0.3.0 admin UI still manages
+it — but the OTC request path no longer consults it. v0.9.0
+(roadmap item #7) shipped the user-management surface that
+consumes the `permission_state` column: `/admin/users` carries
+every user with their state, profile, and sign-up reason, plus
+Grant / Revoke controls that flip the column and write a
+`permission_events` audit row. The capture-form submission also
+fans a `new_beta_request` notification out to every admin/owner
+through the §15 substrate, so the queue surfaces in the inbox +
+email channels admins already have.
+
+The `/admin/allowlist` sub-tab stays in place alongside
+`/admin/users` rather than merging: the two surfaces have
+different keys (allowlist by email pre-sign-up, user list by
+user_id post-sign-up) and a union row would be confusing rather
+than clarifying. The allowlist's role narrowed to "fast-path
+bypass for known-good emails" with the v0.8.0 admission shift;
+v0.9.0 retains that role unchanged.

+single primary action: "Sign in" → the email + one-time-code surface
+at `/login` (per §6.2). Beneath that, a secondary link: "Read the
+full philosophy" → `/philosophy`. The v0.1 landing said "Sign in
+with Gitea"; v0.7.0's email/OTC surface replaced that as the primary
+gesture, with a small "Sign in with Gitea (fallback)" link surviving
+on `/login` itself for the migration window.
+
+`/login` itself is a stepped surface, driven by which auth path the
+viewer is currently on (§6):
+
+1. **Email step.** The viewer enters their email. The frontend
+   consults `GET /auth/passcode/check?email=…` to learn whether
+   this email has a passcode set. The check endpoint is
+   account-enumeration-safe — it returns `has_passcode: false` for
+   both "unknown email" and "known email without passcode", so a
+   probing client cannot distinguish the two from the response.
+2. **Either the passcode step or the OTC code step.** If the email
+   has a passcode set, the viewer is asked for it (v0.10.0).
+   Otherwise an OTC is dispatched and the viewer is asked for the
+   six-digit code from their email (v0.7.0).
+3. **Optional post-OTC passcode-offer step.** After a successful
+   OTC verify on an account with no passcode set, the surface
+   asks "Set a passcode for faster sign-in next time?" — the user
+   can dismiss the offer or set one inline. The skip-for-now path
+   redirects straight to `/`.
+
+The passcode step carries a "Use a code instead" link that
+re-dispatches an OTC and switches to the code step — the same path
+the lockout response (HTTP 423) takes automatically after five
+consecutive failed passcode verifies.
 
 This is the front door. It sets expectation before the user encounters
 the mechanics, so the mechanics (super-drafts, graduation, public
 arguments, AI participation in chat) read as load-bearing rather than
 novel.
 
+v0.8.0 (roadmap item #6) added a third sign-in step the surface
+runs conditionally — on the first OTC sign-in by a previously
+unknown email, the verify response carries `needs_profile=true`
+and the surface prompts for first name, last name, and a free-text
+"why I should be included in the beta" before bouncing the user to
+`/beta-pending`. The page displays a "your request is in review"
+message keyed on `users.permission_state='pending'` (repurposed
+from the v0.3.0 post-OAuth-rejection surface). Anonymous viewers
+and pending viewers see the same read surfaces; only the write
+affordances differ. A persistent thin "Your beta access is in
+review" banner shows on every page (other than `/beta-pending`

+### 14.5 Cookie / privacy consent (v0.13.0)
+
+The framework ships a non-modal cookie consent banner reachable by
+every viewer — authenticated and anonymous alike. The banner appears
+at the bottom of the viewport on first load and stays visible until
+the user makes a choice, after which it hides and the choice is
+persisted. The `/settings/notifications` page carries a "Privacy &
+cookies" tab that surfaces the current choice and re-opens the banner
+on demand.
+
+The choice has three categories, presented as a single-select:
+
+- **Essential only** — the framework's strictly-necessary cookies
+  (sign-in session, signed payloads, the consent-choice record
+  itself). Always on; the user cannot switch this off because the
+  app cannot function without it.
+- **Essential + analytics** — adds the optional analytics layer
+  gated by this choice. As of v0.13.0 no analytics SDK ships in the
+  framework; roadmap item #13 (v0.15.0) lands one behind this gate.
+  Off by default — the user has to opt in.
+- **Essential + analytics + other** — adds third-party embeds or
+  social widgets a deployment may configure. The framework ships no
+  such cookies by default; this category exists so deployments that
+  add them have a categorized opt-in to wire them behind.
+
+Storage shape:
+
+- **Anonymous viewer** — choice persists in `localStorage` only
+  (`rfc-app.cookie-consent.v1`). The same browser carries the choice
+  forward; a different browser, or cleared storage, re-prompts.
+- **Authenticated viewer** — choice persists in the `cookie_consent`
+  row keyed by `user_id`. On sign-in, the server row (if present)
+  overrides the local snapshot; if the server has no row, the local
+  choice is uploaded.
+
+The `essential` flag is permanently true at the API surface. The
+endpoint accepts it for symmetry but never persists a false value.
+A deployment that wants strictly-necessary cookies to be optional
+must change the framework contract, not flip a flag.
+
+The framework exports a small JavaScript helper (`frontend/src/lib/
+consent.js`) for downstream surfaces:
+
+- `getConsent()` — current snapshot.
+- `hasChosen()` — true once the user has made a choice.
+- `onConsentChange(cb)` — subscribe to updates.
+- `setConsent({analytics, other})` — record a new choice locally
+  (the banner / settings surface handles server persistence on top).
+
+Roadmap item #13's analytics SDK (v0.15.0) will read from this helper:
+read consent, then conditionally `import()` the SDK module. The gate
+is wired before the SDK lands so the contract is already in place.
+
+### 14.6 Privacy and cookies policy pages
+
+The framework ships two policy routes:
+
+- `/privacy` — a minimal default privacy policy that describes the
+  framework's stance (what is stored, why, how to revoke consent,
+  how to reach the deployment operator). The page is reachable by
+  anonymous and authenticated viewers alike.
+- `/cookies` — the framework's cookies policy, listing exactly which
+  cookies the framework sets, by category. Self-documenting: a future
+  framework release that adds or removes a cookie updates this page
+  as part of the change.
+
+Each page links to the other and to the §14.5 banner. The consent
+banner links to both.
+
+Deployments override the policy content via two optional build-time
+env vars documented in `frontend/.env.example`:
+
+- `VITE_PRIVACY_POLICY_URL` — an http(s) URL the `/privacy` page
+  links to as the "full deployment policy". The framework's stub
+  always renders above the link so the framework-level contract is
+  always visible; the link layers deployment-specific content on
+  top.
+- `VITE_COOKIES_POLICY_URL` — same shape for `/cookies`.
+
+Both are optional. Unset is the supported default; the stub pages are
+sufficient for a default-config deployment that has nothing
+deployment-specific to add. The framework chose the env-var path over
+a content-repo file because it composes with the existing build-time
+config layer; the content-repo-file alternative is the §19.2
+candidate.

+  below).
+- **Allowlist deprecation.** *Decision deferred past v0.9.0.*
+  v0.9.0 considered merging `/admin/allowlist` into the new
+  `/admin/users` page but kept the surface as a sibling sub-tab:
+  the two have different keys (allowlist by email pre-sign-up,
+  user list by user_id post-sign-up) and a union row would be
+  confusing rather than clarifying. The fast-path-bypass role
+  the allowlist has carried since v0.8.0 stays intact; the
+  cutover to retire the table outright is a later session.
+  Decision points unchanged from v0.8.0: drop the table outright
+  (a schema migration) or leave it as a non-functional surface
+  and remove only the UI (a frontend-only change); how to handle
+  existing `allowed_emails` rows at the cutover (probably: walk
+  them into the pending queue with `permission_state='granted'`
+  for any matching `users` row, leave unmatched rows as a no-op
+  since v0.8.0 doesn't consult them anymore). Earns its session
+  once the v0.9.0 admin queue has run long enough to confirm the
+  allowlist's bypass role is no longer pulling weight.
+- **Admin notification on new beta request.** *Shipped in v0.9.0
+  (roadmap item #7).* The `POST /api/auth/me/beta-request`
+  handler now calls `notify.fan_out_new_beta_request`, which
+  fans a `new_beta_request` event (category `admin-actionable`,
+  rfc_slug NULL) out to every owner / admin. The §15 chokepoint
+  handles the SSE broadcast and the §15.4 email dispatch; the

+  toggle is on (the default for owners + admins).

+  v0.9.0.* The new flip endpoint stamps `permission_decided_by` +
+  writes a `permission_events` row but does not yet signal the
+  affected user that their state changed. A future release could
+  fire a `personal-direct` notification (event_kind
+  `permission_change_affecting_me`, already in the §15.1 enum) so
+  a granted user sees "Your beta-access request was approved" in
+  their inbox and email, and a revoked user sees a parallel
+  refusal notice. Decision points: does revocation include a

+  comment); does grant carry a welcome message (probably no —

+  could add a free-text reason input that lands in the
+  `permission_events.details` JSON column (no schema change

+  v0.7.0 keeps `/auth/callback` functional and links to it as a
+  "Sign in with Gitea (fallback)" affordance on the new `/login`
+  surface, so users with active OAuth sessions or older invite
+  paths still have a way in during the migration window. A later
+  release retires the route entirely. Decision points: how do we
+  know "every active user has signed in via OTC at least once"
+  (probably: a `users.otc_first_signed_in_at` timestamp added in
+  v0.7.x and a query that confirms 100% population), how do we
+  handle users who never come back (probably: silently leave them
+  with stale rows; OAuth callback returning 404 is a sufficient
+  message), and whether the `/auth/login` and `/auth/callback`
+  routes get a tombstone redirect to `/login` or just 404. Earns
+  its session once the OTC adoption curve flattens.
+- **Device trust (30-day skip).** *Surfaced by v0.7.0 — the
+  signed-in cookie already lasts 30 days via SessionMiddleware,
+  but every sign-in still requires a fresh OTC or passcode.* The
+  roadmap item-#9 candidate adds a "trust this device" affordance
+  on the verify step that issues a longer-lived rotating token,
+  so returning visitors on the same device skip both the OTC and
+  the passcode step. The shape question is whether the trust is a
+  signed cookie distinct from the session, a row in a `device_trust`
+  table keyed by a random device-id, or a property of the session
+  itself; and whether the trust survives password-equivalent events
+  — v0.10.0's passcode-change and passcode-clear gestures are the
+  v1 instances — or only survives explicit logout. Earns its

+- **Cloudflare Turnstile (or equivalent) on `/auth/otc/request`.**
+  *Surfaced by v0.7.0 — the endpoint is now the new abuse hot
+  path.* Per-email cooldown stops the trivial loop; what it
+  doesn't stop is a distributed scrape that fans out across a

+  this email is not" signal indirectly (timing differences, SMTP
+  bounce-rate observation). The roadmap item-#10 candidate gates
+  the request endpoint behind a one-step browser-side challenge
+  before the bcrypt hash + SMTP send. Open questions: which

+  how the deployment configures it (`TURNSTILE_SITE_KEY` +
+  `TURNSTILE_SECRET_KEY` env vars, gated by `if

+  also hard-coded. A deployment that wants tighter or looser rules
+  has to fork the constants. Two env vars
+  (`PASSCODE_LOCKOUT_AFTER_ATTEMPTS`,
+  `PASSCODE_LOCKOUT_DURATION_MINUTES`) would let operators

+- **Per-IP rate-limiting on `/auth/passcode/verify`.** v0.10.0's
+  lockout is per-account: 5 failures against the same email lock
+  that account for 15 minutes. A distributed attacker that knows

+  one account's lockout. Adding a per-IP throttle (e.g., 30
+  passcode-verify attempts / minute / IP, returning HTTP 429) is
+  the natural pairing. Defer-able — the per-account lockout is
+  the v1 shape that closes the loud-loop case; the per-IP
+  distributed case waits on evidence. Touches §6.2 and §17.
+- **Passcode-change "still know your old passcode" challenge.**
+  v0.10.0 lets a signed-in user replace their passcode from
+  `/settings/notifications` without re-entering the old one — the
+  session is sufficient. A future hardening pass may require the
+  old passcode (or a fresh OTC verify) before accepting the
+  change, to mitigate session-hijack scenarios where the attacker
+  rotates the passcode to lock the legitimate owner out. The same
+  question applies to the clear gesture. Earns its session if
+  session-hijack becomes a real threat surface.
+- **Passkey / WebAuthn.** A much heavier next step than passcodes:
+  hardware-backed device credentials that resist phishing. The

+  type a code every time" ergonomic problem; passkeys are the

+  (`VITE_PRIVACY_POLICY_URL`, `VITE_COOKIES_POLICY_URL`) that the
+  framework's stub pages link out to. The alternative — accepting
+  a markdown file path the framework renders inline, parallel to
+  `PHILOSOPHY_PATH` per §14.2 — was deferred. The two compose:
+  a deployment could carry both an inline file (rendered above
+  the fold) and an external link (rendered below). Earns its own
+  topic when a real deployment ships a policy long enough that
+  the link-out shape bites and renders the link unread.
+- **Global Privacy Control / Do-Not-Track headers.** v0.13.0
+  scoped the consent surface to the in-app banner and did not
+  honor browser-side GPC or DNT signals. The framework's stance
+  is that the in-app banner is the authoritative gesture — a
+  user who clears their consent in the banner has expressed
+  intent, and the GPC header is a coarser signal layered on top.
+  Earns its own topic if a regulatory regime emerges that treats
+  GPC as the legally-binding gesture, in which case the framework
+  would honor GPC as an automatic "essential only" choice unless
+  the user explicitly broadened it in-app.
+- **Multi-language consent text.** The banner ships English-only.
+  i18n of the framework's user-facing strings is a broader topic
+  than the consent banner; carrying the work in that future topic
+  rather than as a per-surface translation pass.
+- **Analytics SDK gating against `consent.js`.** Roadmap item #13
+  (target v0.15.0) lands the analytics SDK behind
+  `lib/consent.js`'s `getConsent().analytics` gate. The framework
+  contract is already in place; the SDK integration is the work
+  the item ships. Listed here so the dependency is documented.

+"""Outbound OTC email — a thin wrapper over the existing SMTP layer.
+
+The §15.4 notification mailer in `email.py` is purpose-built for
+inbox-driven mail (unsubscribe footers, quiet-hours holds, bundling).
+OTC mail is structurally different: it carries a credential, has no
+inbox row behind it, and ignores user-preferences (a contributor
+who's opted out of every notification still needs to receive the
+code they explicitly requested).
+
+So this module reuses `EmailConfig.from_env()` for the SMTP plumbing
+and the From identity, but writes its own envelope. In dev (no
+SMTP_HOST set), the envelope is logged at INFO level and pushed to
+the same `_SENT` buffer the notification mailer uses, so the
+integration tests can assert on the outbound shape without standing
+up an SMTP server.
+
+The send is synchronous. The `/auth/otc/request` endpoint always
+returns 202 regardless of send outcome — the user-facing surface
+doesn't know whether the SMTP relay was reachable, since revealing
+that would let an attacker probe for valid emails on a tight loop.

+"""§6.2 / v0.7.0 / v0.8.0: email + one-time-code sign-in.
+
+Replaces the Gitea OAuth gesture as the primary human-auth path. The
+Gitea bot user + token are still needed for server-side git
+operations (repo reads, PR creation); only the operator-facing
+sign-in surface moves through this module.
+
+The shape:
+
+  * `request_code(email)` generates a 6-digit decimal code,
+    hashes it (bcrypt), stores the hash + expiry in `otc_codes`,
+    and dispatches a plain-text email via `email_otc.send`. It
+    invalidates any prior unused codes for the same email so a
+    re-request keeps the surface to one outstanding code per
+    address. The TTL comes from `OTC_TTL_MINUTES` (default 10).
+    A per-email cooldown (`OTC_REQUEST_COOLDOWN_SECONDS`, default
+    60) refuses back-to-back requests inside the window.
+
+  * `verify_code(email, code)` walks the most recent unconsumed
+    non-expired row for the email, checks the bcrypt hash, marks
+    the row consumed, and returns the linked or freshly-provisioned
+    user row.
+
+  * `provision_or_link_user(email)` is the migration path: if a
+    `users` row already carries `email` (case-insensitive), it is
+    reused — `gitea_id` is left alone so a grandfathered OAuth-era
+    user keeps the linker intact. Otherwise a fresh contributor
+    row is provisioned with `gitea_id = NULL`, `gitea_login = NULL`,
+    and `permission_state = 'pending'` (v0.8.0 — see below).
+
+The endpoints in `main.py` thin-wrap this module.
+
+v0.8.0 (roadmap item #6) replaces the v0.3.0 `allowed_emails` gate at
+the request surface. The request handler used to silently drop OTC
+requests for emails not on the allowlist; now any valid email
+receives a code. The admission gate moves to `permission_state` on
+the freshly-provisioned `users` row: a fresh user lands in 'pending'
+and waits for an admin grant before write endpoints accept them.
+Read surfaces stay open (the same blast radius v0.6.0 / item #4
+already audited for anonymous viewers).
+
+The `allowed_emails` table itself stays in the schema as a
+fast-path bypass — the admin UI from v0.3.0 continues to manage it,
+and a future release (v0.9.0's admin user-management page) collapses
+the two admission surfaces into one. The OTC request path no
+longer consults the table.

+"""§6.2 / v0.10.0: user-set passcodes after OTC (roadmap item #8).
+
+After a successful OTC sign-in, a contributor may set a passcode and
+use email + passcode for subsequent sign-ins. OTC remains the fallback
+— a forgotten passcode is recovered by requesting a fresh OTC.
+
+This module is the state machine behind the four `/auth/passcode/*`
+endpoints (`set`, `clear`, `verify`, `check`). The endpoints in
+`main.py` thin-wrap these helpers in the same shape the OTC module
+uses (see `otc.py`).
+
+Shape:
+
+  * `set_passcode(user_id, passcode)` — bcrypt-hash the passcode and
+    write it to `users.passcode_hash` + `users.passcode_set_at`.
+    Validation (length, denylist) happens here, not at the endpoint,
+    so the rule lives in one place. Replaces any prior passcode.
+  * `clear_passcode(user_id)` — null out `passcode_hash` and
+    `passcode_set_at`. The user is back to OTC-only.
+  * `verify_passcode(email, passcode)` — locate the user by email,
+    check lockout, compare via bcrypt, manage the failure counter,
+    and return a populated `SessionUser` on success.
+  * `passcode_status(email)` — does this email have a passcode set?
+    Used by the `/auth/passcode/check` endpoint that the Login.jsx
+    flow consults after the user types their email.
+
+Lockout is a v1 shape: 5 consecutive failures sets
+`passcode_locked_until` to `now + 15 minutes`, after which a verify
+attempt that lands inside the window returns HTTP 423. The OTC path
+is unaffected by the lockout — a user can request and verify a fresh
+OTC to sign in while their passcode is locked out, and `verify_code`
+in `otc.py` does not consult these columns.
+
+The lockout window and the failure threshold are hard-coded here.
+Tuning them via env vars (or moving to per-IP rate-limiting) is a
+§19.2 candidate; see SPEC §19.2.

+--                 symmetry with the analytics / other flags rather than
+--                 because the user can switch it off.
+--   - analytics:  reserved for the §13 analytics SDK gating that lands
+--                 in v0.15.0. Off by default; opt-in via the banner.
+--   - other:      everything else (third-party embeds, social widgets).
+--                 Off by default; opt-in via the banner.
+--
+-- A NULL recorded_at means "no choice yet" — the banner should re-prompt
+-- the next time the user signs in on a fresh device. Once recorded_at is
+-- set, the banner is hidden until the user re-opens it from the
+-- /settings/notifications "Privacy & cookies" tab.
+--
+-- The row is created lazily on first PUT. Absence of a row is equivalent

+-- §6.1 / §6.2 / §14.1 / v0.8.0: open beta-access request flow (roadmap item #6).
+--
+-- This release replaces v0.3.0's `allowed_emails` allowlist as the
+-- admission control. Anyone with a valid email can sign in via the
+-- v0.7.0 OTC flow; a fresh user lands in `permission_state='pending'`
+-- until an admin grants access. The first-OTC flow captures three
+-- profile fields (first name, last name, free-text "why I should be
+-- included in the beta") that the admin sees when triaging the
+-- request queue. The `allowed_emails` table stays in the schema as a
+-- fast-path bypass — populated rows are still readable by the
+-- existing admin UI; the OTC `/request` handler no longer consults
+-- it. v0.9.0's admin user-management page will replace the
+-- allowlist UI entirely.
+--
+-- Schema additions:
+--
+--   * `permission_state` — three-state CHECK: 'pending' | 'granted' |
+--     'revoked'. Default 'granted' so every row at migration time
+--     passes through unaffected; only newly provisioned OTC users
+--     land in 'pending' (the OTC verify path sets the column
+--     explicitly on a fresh row, per `app/otc.py`). 'revoked' is the
+--     admin gesture for an account that earned a grant then later
+--     lost it; v0.8.0 doesn't surface a revoke UI, but the schema
+--     slot is here so v0.9.0's admin user-management page can flip
+--     the column without another migration.
+--
+--   * `first_name`, `last_name` — nullable TEXT. Captured on the
+--     first OTC sign-in via `POST /auth/me/beta-request`. Existing
+--     rows (OAuth-era users, OTC users provisioned in v0.7.0) carry
+--     NULL through the migration; the admin queue treats an
+--     unpopulated capture as "auto-grandfathered" since the row's
+--     `permission_state` is already 'granted'.
+--
+--   * `beta_request_reason` — nullable TEXT. The free-text "why I
+--     should be included" from the capture form. Bounded to ~4000
+--     chars at the endpoint layer (no DB-level constraint —
+--     SQLite's TEXT is unbounded).
+--
+--   * `permission_decided_by` — nullable INTEGER. The `users.id` of
+--     the admin who flipped `permission_state` from 'pending' to
+--     'granted' (or 'granted' to 'revoked'). NULL for grandfathered
+--     rows (they were never decided — they passed through at
+--     migration). ON DELETE SET NULL because losing the admin row
+--     should not cascade-delete the user whose access they granted.
+--
+--   * `permission_decided_at` — nullable TEXT timestamp (ISO 8601,
+--     same shape as the existing `created_at` / `last_seen_at`).
+--     Co-populated with `permission_decided_by` on each decision.
+--
+-- Grandfathered-row invariant:
+--
+--   Every row that exists at migration time has
+--   `permission_state='granted'` and `permission_decided_by=NULL`
+--   (the column default + NULL preservation). v0.8.0's auth gate
+--   reads `permission_state='granted'` as the admission check, so
+--   no existing user is locked out by the upgrade. v0.7.0's OTC
+--   path is patched in the same release to set
+--   `permission_state='pending'` explicitly on a fresh row, so the
+--   gate engages only for users provisioned after the upgrade.

+-- §6.2 / v0.10.0: user-set passcodes after OTC (roadmap item #8).
+--
+-- After a successful OTC sign-in, a contributor may set a passcode
+-- (numeric PIN or short alphanumeric). Subsequent sign-ins on the same
+-- account can use email + passcode instead of email + OTC. OTC remains
+-- the structural fallback — a forgotten passcode is recovered by
+-- requesting a fresh OTC and signing in via that path. Per-account
+-- lockout after 5 consecutive verify failures redirects the user to
+-- the OTC path for 15 minutes; the OTC path itself is unaffected by
+-- the passcode lockout (a locked-out user can still receive a fresh
+-- code and sign in).
+--
+-- The columns are additive to the `users` table from `012_otc.sql`.
+-- v0.8.0's `permission_state` column (roadmap item #6) lands in the
+-- driver's integration order ahead of this migration; we do not touch
+-- that column here. v0.7.0's nullable-`gitea_id`/`gitea_login` shape
+-- is preserved verbatim.
+--
+-- Storage shape:
+--
+--   * `passcode_hash` (nullable) — bcrypt hash of the passcode.
+--     NULL means "no passcode set"; the user is OTC-only.
+--   * `passcode_set_at` (nullable) — timestamp of the most recent
+--     `passcode/set` call. Updated when a passcode is set or
+--     replaced; cleared when the passcode is removed.
+--   * `passcode_failed_attempts` — count of consecutive failed
+--     verify attempts since the last successful verify (or since
+--     the lockout cleared). Resets to 0 on success and on lockout
+--     expiry. Defaults to 0 so existing rows post-migration are
+--     not implicitly half-locked.
+--   * `passcode_locked_until` (nullable) — if populated and the
+--     timestamp is in the future, passcode verify is refused with
+--     HTTP 423. Cleared on successful verify after the window
+--     expires, or by the operator via direct DB intervention if
+--     ever needed (no admin endpoint surfaces this in v1).
+--
+-- v0.10.0 introduces no new env vars. The lockout window (5 attempts,
+-- 15 minutes) is hard-coded in `backend/app/passcode.py`; raising or
+-- lowering it is a future-§19.2 candidate. Passcode hashing reuses
+-- the bcrypt dependency added in v0.7.0 for OTC; no new secret is
+-- required (the existing `SECRET_KEY` continues to sign sessions).
+--
+-- Note on SQLite: ALTER TABLE ... ADD COLUMN is supported, so this
+-- migration does not need the rebuild dance that `012_otc.sql`
+-- required. The runner wraps each file in a single BEGIN/COMMIT
+-- block — see `backend/app/db.py` — so either every ADD COLUMN

+"""End-to-end integration tests for v0.9.0's admin user-management page
+and new-beta-request notifications (roadmap item #7, §6.1 / §15).
+
+The release lands two halves of the same surface:
+
+  * **Admin notification on new beta request.** When a pending user
+    submits `POST /api/auth/me/beta-request`, every owner/admin
+    receives a `new_beta_request` notification (the §15 substrate
+    insert lands the row; the §15.4 email path dispatches subject to
+    the recipient's `email_admin_actionable` toggle).
+
+  * **Admin user-management surface** at `/admin/users`. The
+    `GET /api/admin/users` listing carries every user with their
+    permission_state, profile fields, sign-up reason, and decision
+    audit. The new `POST /api/admin/users/<id>/permission` endpoint
+    flips the column and writes a `permission_events` row.
+
+The tests prove:
+
+  * The first beta-request submission fans a `new_beta_request`
+    row out to every admin/owner (and not to the requester
+    themselves). The row carries the captured profile in
+    `payload.extras`.
+  * Re-submitting the form from the same pending user doesn't
+    re-fan (we only notify on the row's first complete state).
+  * `GET /api/admin/users` carries the v0.9.0 columns
+    (permission_state, first/last/reason, decided_by).
+  * `POST /api/admin/users/<id>/permission` flips the state,
+    stamps decided_by/at, and writes a `permission_events` row.
+  * The endpoint refuses self-flip (422) and refuses non-admin
+    callers (403).
+  * The endpoint accepts only the three valid states (422 on
+    anything else).

+"""End-to-end integration tests for v0.8.0's open beta-access request
+flow (§6.1 / §14.1, roadmap item #6).
+
+The release replaces v0.3.0's `allowed_emails` allowlist as the
+admission gate. Any valid email can sign in via the v0.7.0 OTC flow;
+a fresh user lands in `permission_state='pending'` until an admin
+grants access. The first-OTC flow captures first name, last name,
+and a free-text "why I should be included in the beta" via a new
+`POST /api/auth/me/beta-request` endpoint.
+
+The tests prove:
+
+  * A fresh OTC user lands `permission_state='pending'` with empty
+    profile fields, and the verify-response carries `needs_profile=true`.
+  * `POST /api/auth/me/beta-request` populates the three fields and
+    leaves the row in `pending`.
+  * A pending user is refused write endpoints (representative
+    samples: propose RFC, post discussion thread). The refusal is
+    403 (not 401 — they're authenticated, just not granted).
+  * An admin-grant flow promotes pending → granted. v0.8.0 doesn't
+    ship an admin UI for this (deferred to item #7 / v0.9.0), so
+    the test flips the column directly via DB and asserts that
+    `require_contributor` now admits the user.
+  * A grandfathered user (existing row pre-migration, default
+    `permission_state='granted'`) is unaffected — write endpoints
+    accept them.
+  * The `/auth/otc/request` endpoint accepts any email — the
+    v0.7.0 allowlist gate is gone from this path. The `allowed_emails`
+    table stays in the schema; the admin UI from v0.3.0 continues to
+    manage it for the fast-path bypass deployments may use.

+"""End-to-end integration tests for the v0.7.0 email/OTC sign-in
+vertical (§6.2).
+
+The release replaces the Gitea OAuth gesture as the primary human
+sign-in path. The tests prove:
+
+  * `/auth/otc/request` is rate-limited per-email — back-to-back
+    requests inside `OTC_REQUEST_COOLDOWN_SECONDS` are refused with
+    429 (the loud-failure shape the spec calls out).
+  * The happy path: request → code lands in the outbound buffer →
+    verify with the code → session cookie surfaces an authenticated
+    user via `/api/auth/me`.
+  * Expired codes refuse with 400.
+  * Already-consumed codes refuse with 400 on re-use.
+  * Wrong codes refuse with 400.
+  * Allowlist gate (v0.8.0 update): v0.7.0 silently dropped requests
+    for emails not on `allowed_emails`. v0.8.0 (item #6) removed
+    that gate from the request path; the admission gate is now
+    `permission_state` on the freshly-provisioned `users` row,
+    asserted in test_beta_access_vertical.py. The tests below
+    confirm v0.8.0's open-request shape for both on-list and
+    off-list emails.
+  * Migration link: an existing OAuth-era user (with a `users.email`
+    row) is linked by email on first OTC sign-in — `gitea_id` is
+    preserved.
+  * Provisioning path: an unrecognized email creates a fresh
+    contributor row with `gitea_id = NULL`.
+
+The Gitea bot user + token are still required at process construction
+(every test harness sets the same `GITEA_*` env vars); the OTC flow
+itself never reaches Gitea. The fakes from `test_propose_vertical`
+remain in scope so the rest of the app boots cleanly.

+"""End-to-end integration tests for the v0.10.0 user-set passcode
+vertical (§6.2, roadmap item #8).
+
+After a successful OTC sign-in the user can set a passcode and use
+email + passcode for subsequent sign-ins. OTC remains the structural
+fallback — these tests prove:
+
+  * `/auth/passcode/set` requires an active session.
+  * `/auth/passcode/check` returns `has_passcode` without leaking the
+    hash, the set-at stamp, or the lockout state.
+  * Happy path: OTC sign-in → set passcode → sign out → email +
+    passcode signs in (no OTC roundtrip).
+  * Wrong passcode increments the failure counter without locking.
+  * Five consecutive failures lock the passcode path (HTTP 423) and
+    persist `passcode_locked_until` on the user row.
+  * The lockout expires after `passcode_locked_until`; a verify
+    attempt past the window succeeds again and clears the counter.
+  * The OTC path is unaffected by the passcode lockout — a user
+    whose passcode is locked can still request and verify a fresh
+    OTC to sign in.
+  * Clearing the passcode wipes the hash; subsequent verify refuses
+    with the no-passcode failure shape.
+  * Setting a new passcode replaces the prior one (and resets the
+    failure counter / lockout state).
+  * `passcode_set_at` updates on every set call.
+  * The validation denylist refuses obvious patterns (e.g. `0000`,
+    `1234`).
+  * Passcode length is enforced (4-20).
+
+The fakes from `test_propose_vertical` give us a working app harness.
+The OTC envelope buffer from `test_otc_vertical` is reused for the
+OTC roundtrips this suite needs.

+//                        for admin grant gains them nothing.

+//                        keyboard shortcut.
+//
+//   3. 'capture-profile' (v0.8.0, §6.1) First name, last name, and "why
+//                        I should be included in the beta" → POST
+//                        /api/auth/me/beta-request → redirect to
+//                        /beta-pending. The user's row stays
+//                        permission_state='pending' until an admin
+//                        grants access; they can set a passcode later
+//                        from settings, or on a future sign-in once
+//                        granted.
+//
+//   4a. 'offer-passcode' (v0.10.0) "Set a passcode for faster sign-in
+//                        next time?" Yes → 'set-passcode'. Skip → "/".
+//
+//   4b. 'set-passcode'   Pick a passcode (4–20 chars) → POST
+//                        /auth/passcode/set → redirect to "/". A
+//                        "Skip for now" link also redirects to "/".
+//
+// Server-side, /auth/otc/request returns 202 uniformly and
+// /auth/passcode/check returns has_passcode=false for an unknown
+// email, so this surface never distinguishes "we couldn't reach you"
+// from "we don't know you" — an unknown email always lands in the
+// OTC path with no account-enumeration signal.
+//
+// The legacy Gitea OAuth callback remains at /auth/login →
+// /auth/callback during the v0.7.0 migration; we surface a "Sign in
+// with Gitea" link as a fallback in the footer so users with active
+// OAuth sessions or older invite emails still have a path. We hide
+// the fallback on 'capture-profile' so a half-captured pending user
+// doesn't bail out into the OAuth path mid-form.

+// Privacy.jsx — v0.13.0 / roadmap item #11 / SPEC §14.5.
+//
+// The framework's default privacy policy page. Reachable by anonymous
+// and authenticated viewers alike at `/privacy`. The text below is a
+// minimal stub that describes the framework's stance; deployments are
+// expected to override it via the `VITE_PRIVACY_POLICY_URL` env var.
+//
+// When `VITE_PRIVACY_POLICY_URL` is set:
+//   - http(s) URL → the page renders the framework's stub above a
+//     "Read the full deployment policy" link to the configured URL.
+//     We don't iframe-embed third-party policy hosts because their
+//     Content-Security-Policy frequently refuses framing; the link is
+//     the predictable affordance.
+//
+// The framework's stub is intentionally short — the rules that matter
+// to a user are: (1) what categories of cookies the app sets, (2) how
+// to change consent, (3) where to reach the deployment operator with a
+// complaint. Each deployment's content repo can carry a fuller version.

+
+        <h2>What we store</h2>
+        <p>
+          {appName} runs on the Wiggleverse RFC framework. The framework
+          stores the identity you sign in with (your Gitea login,
+          display name, email, and avatar URL), the proposals and edits
+          you author, the discussion threads you participate in, and
+          your notification preferences. Authoring is public by design —
+          this is a framework for public-async RFC work, and threads,
+          changes, and PRs are visible to anyone who reaches the
+          deployment. Settings (notification toggles, quiet hours, mute
+          list, cookie consent) are private to your account.
+        </p>
+
+        <h2>Cookies</h2>
+        <p>
+          The app sets a small set of cookies. The full list is on the{' '}
+          <Link to="/cookies">cookies policy page</Link>. You can choose
+          which categories you allow from the consent banner shown on
+          your first visit or from <Link to="/settings/notifications">
+          Settings &rarr; Privacy &amp; cookies</Link> any time
+          afterwards.
+        </p>
+
+        <h2>Analytics</h2>
+        <p>
+          The framework supports an optional anonymous analytics layer
+          gated behind your consent choice. As of v0.13.0 no analytics
+          SDK ships in the framework; deployments that enable analytics
+          do so via a later framework version (roadmap item #13). The
+          consent toggle exists today so the gate is already in place
+          when the SDK lands.
