# GLUECRON BUILD BIBLE

**This file is the single source of truth for the GlueCron build.**

**Every Claude agent MUST read this file in full before touching code. No exceptions.**

GlueCron is a GitHub replacement — AI-native code intelligence, green ecosystem enforcement, git hosting, automated CI. It is production infrastructure for multiple downstream platforms. Production cannot stop.

---

## 1. AGENT POLICY (READ FIRST, FOLLOW ALWAYS)

### 1.1 Required reads at session start
1. `BUILD_BIBLE.md` (this file) — complete
2. `CLAUDE.md` — stack + architecture
3. `README.md` — user-facing overview
4. Most recent commit on the current branch (`git log -1 --stat`)

### 1.2 Do-not-undo rule
- Anything listed in **§4 LOCKED BLOCKS** is shipped and must not be deleted, renamed, or semantically altered without the owner's explicit written permission in the current session.
- "Refactor" is not permission. "Clean up" is not permission. "Simplify" is not permission.
- If a locked file seems wrong, open an issue in the plan and keep going on a new block.

### 1.3 Continuous-build rule
- The owner runs many parallel projects. Do not stop work to ask for clarification that can be inferred from this file.
- Default behaviour when a block is partially complete: **finish it, run tests, commit, push, start the next block**.
- Only stop for genuinely blocking decisions: destructive operations, architectural reversals, requests outside this plan, or repeated test failures you can't diagnose.
- Never stop because "the session might run out." Commit what works and keep building.

### 1.4 Branch + commit rules
- Development branch: whatever the current session was told (check session opening message). Fall back to `main` if none given.
- One commit per completed block. Message format: `feat(BLOCK-ID): <summary>`.
- Push after every commit with `git push -u origin <branch>`.
- Never force-push. Never `--no-verify`. Never amend published commits.

### 1.5 Quality bars (non-negotiable)
- `bun test` must pass before every commit.
- New features ship with tests in `src/__tests__/`.
- New routes use `softAuth` or `requireAuth` middleware.
- New DB tables have a corresponding migration in `drizzle/`.
- AI features use `isAiAvailable()` guards and degrade gracefully without `ANTHROPIC_API_KEY`.
- Every user-facing failure mode has a fallback — no 500s reach the UI.

### 1.6 Green-ecosystem-by-default
- Every new repo auto-configures: gates on, branch protection on, labels seeded, CODEOWNERS synced, welcome issue posted.
- Users can opt out per feature but defaults are maximum-green.
- Nothing broken ever reaches production, the website, or the customer.

### 1.7 Parallelism rule (added per owner request)
- **Default to spawning sub-agents whenever work can be parallelised.** Owner-cost of an idle main thread is high; owner-cost of an extra agent is near-zero.
- Independent files = parallel agents. Schema-only edits, new route files, doc updates, test additions, codebase research — all of these run in parallel by default unless they collide.
- Coordinate file ownership: one agent per file. Never let two agents edit the same file. Mounting + middleware integration stay on the main thread to avoid merge conflicts.
- When launching multiple agents, send them in a single message with multiple Agent tool calls so they actually run concurrently.
- The main thread is responsible for: reviewing each agent's output before integrating, running the test suite, and committing. Trust-but-verify — read the changes, don't just rely on the agent's summary.

## 2. GITHUB PARITY SCORECARD

Legend: ✅ shipped · 🟡 partial · ❌ not built

### 2.1 Repository hosting
| Feature | Status | Notes |
|---|---|---|
| Git Smart HTTP (clone / push / fetch) | ✅ | `src/routes/git.ts`, `src/git/protocol.ts` |
| SSH keys | ✅ | `ssh_keys` table, `src/routes/settings.tsx` |
| Public / private visibility | ✅ | `repositories.isPrivate` |
| Forking | ✅ | `src/routes/fork.ts` |
| Stars | ✅ | `stars` table, `/:owner/:repo/star` |
| Topics | ✅ | `repo_topics` table |
| Archive / disable repo | ✅ | I1 — `src/routes/repo-settings.tsx` archive toggle; `RepoHeader` renders an "Archived" badge when `is_archived=true`. |
| Repository transfer | ✅ | I3 — `src/routes/repo-settings.tsx` transfer form + `POST /:owner/:repo/settings/transfer`; ownership change recorded in `repo_transfers` audit table. Reject conflicts (target owner already has a repo by that name) with a redirect. |
| Template repositories | ✅ | I2 — `drizzle/0022_repo_templates.sql` adds `is_template`. `src/routes/templates.ts` serves `POST /:owner/:repo/use-template` (git clone --bare into caller's namespace). "Use this template" CTA rendered on the public repo page. |
| Repository mirroring | ✅ | I9 — pull-style mirror of an upstream git URL. `drizzle/0026_repo_mirrors.sql` adds `repo_mirrors` (one-per-repo config) + `repo_mirror_runs` (audit log). `src/lib/mirrors.ts` validates URLs (https/http/git only, rejects ssh/file/shell metacharacters), runs `git fetch --prune --tags` via `Bun.spawn` with a 5-min timeout + `GIT_TERMINAL_PROMPT=0`. `src/routes/mirrors.tsx` exposes `/:owner/:repo/settings/mirror` + `/admin/mirrors/sync-all`. |

### 2.2 Code browsing
| Feature | Status | Notes |
|---|---|---|
| File tree browser | ✅ | `src/routes/web.tsx` |

| Semantic / embedding search | ✅ | D1 — `code_chunks` table + lexical fallback, optional Voyage `voyage-code-3`; `src/lib/semantic-search.ts`, `src/routes/semantic-search.tsx` |
| Symbol / xref navigation | ✅ | I8 — `src/lib/symbols.ts` regex-based extractor for ts/js/py/rs/go/rb/java/kt/swift; on-demand indexer persists top-level definitions into `code_symbols` (0025). `src/routes/symbols.tsx` serves `/:owner/:repo/symbols` overview + A–Z list, `/:owner/:repo/symbols/search?q=` prefix search, `/:owner/:repo/symbols/:name` definition detail. Owner-only reindex. |
| Dependency graph | ✅ | J1 — `src/lib/deps.ts` parses package.json / requirements.txt / pyproject.toml / go.mod / Cargo.toml / Gemfile / composer.json without a TOML lib. `src/routes/deps.tsx` serves `/:owner/:repo/dependencies` grouped by ecosystem with per-ecosystem counts; owner-only reindex walks the default-branch tree (max 200 manifests, 1MB each). `drizzle/0028_repo_dependencies.sql` adds `repo_dependencies`. |
| Security advisories / Dependabot alerts | ✅ | J2 — curated 12-entry seed list + minimal semver range matcher cross-referenced against J1 dep rows. `src/lib/advisories.ts` + `src/routes/advisories.tsx` serve `/:owner/:repo/security/advisories` (open) + `/all`, owner-only `POST /scan`, and per-alert dismiss/reopen. `drizzle/0029_security_advisories.sql` adds `security_advisories` + `repo_advisory_alerts`. |

Green "Verified" badge rendered on commit list + detail when a registered key matches. `src/lib/signatures.ts` + `src/routes/signing-keys.tsx` + `drizzle/0030_signing_keys.sql`. |
| Repository rulesets (push policy engine) | ✅ | J6 — named policies group N rules at active/evaluate/disabled enforcement. Pure evaluator `evaluatePush(rulesets, ctx)` → `{allowed, violations}`. Six rule types: commit_message_pattern, branch_name_pattern, tag_name_pattern, blocked_file_paths, max_file_size, forbid_force_push. Glob-lite matcher (`*` = non-slash, `**` = anything). Owner-only CRUD at `/:owner/:repo/settings/rulesets`. `src/lib/rulesets.ts` + `src/routes/rulesets.tsx` + `drizzle/0032_repo_rulesets.sql`. |
| Commit status API (external CI signals) | ✅ | J8 — external systems POST per-commit (sha, context) statuses with state pending/success/failure/error. Combined rollup reduces to worst state. Public list + combined endpoints; write requires owner auth. Rendered on commit detail view as a pill row. `src/lib/commit-statuses.ts` + `src/routes/commit-statuses.ts` + `drizzle/0033_commit_statuses.sql`. |

## 3. BUILD PLAN (BLOCKS)

Each block is a self-contained unit. Order matters for dependencies. Each block ends with tests + commit + push.

### BLOCK A — Hardening the current surface
Polish what's shipped before adding more. **Priority: do this first if parity gaps are minor.**
- **A1** — Dark/light theme toggle (cookie, CSS variable swap) ✅
- **A2** — Audit log UI page (`/settings/audit` + `/:owner/:repo/settings/audit`) ✅
- **A3** — Reactions UI on issues / PRs / comments (data exists) ✅
- **A4** — Draft PR toggle + filter ✅
- **A5** — Issue + PR templates (`.github/*_TEMPLATE.md` auto-prefill) ✅
- **A6** — Saved replies per user ✅
- **A7** — Environments + deployment history UI (`deployments` table) ✅
- **A8** — Email notifications (opt-in, provider-pluggable) ✅

**BLOCK A COMPLETE.** Next: BLOCK B (Identity + orgs).

### BLOCK B — Identity + orgs
- **B1** — Organizations (schema: `organizations`, `org_members`, `teams`, `team_members`) → ✅ shipped (`6563f0a`)
  - Helpers in `src/lib/orgs.ts`: slug validation, role rank, reserved-slug set, loaders
  - Routes in `src/routes/orgs.tsx`: list / create / profile / people / teams / team detail
  - Role-based guards: admin adds members, owner grants owner, last-owner demote/remove blocked
  - All sensitive actions `audit()`'d (org.create, member.add/role/remove, team.create, team.member.add/remove)
- **B2** — Repos owned by orgs (nullable `repositories.orgId`) → ✅ shipped (`7437605`)
- **B3** — Team-based CODEOWNERS (`@org/team` resolution) → ✅ shipped (`40d3e3f`)
- **B4** — 2FA / TOTP (enroll, recovery codes) → ✅ shipped (`7298a17`)
- **B5** — WebAuthn / passkeys → ✅ shipped (`2df1f8c`)
- **B6** — OAuth 2.0 provider (third-party apps can request access) → ✅ shipped (pending final commit)

### BLOCK C — Runtime + hosting
- **C1** — Actions-equivalent workflow runner → ✅ shipped (`eafe8c6`)
  - Workflow YAML parser (`src/lib/workflow-parser.ts`) — hand-rolled subset
  - Background worker (`src/lib/workflow-runner.ts`) — Bun.spawn, size-capped logs, SIGTERM→SIGKILL timeouts
  - Auto-discovery from `.gluecron/workflows/*.yml` on default-branch push
  - UI at `/:owner/:repo/actions` with manual trigger + cancel
- **C2** — Package registry (npm protocol) → ✅ shipped
  - Packument + tarball + publish + yank via `PUT /npm/<name>` + `GET /npm/<name>`
  - PAT (`glc_`) bearer auth for CLI clients; add `//host/npm/:_authToken=<PAT>` to .npmrc
  - Container registry deferred (schema ready for it)
- **C3** — Pages / static hosting → ✅ shipped
  - Serves `/:owner/:repo/pages/*` from the latest successful `pages_deployments` row
  - Auto-records on push to the repo's configured source branch (default `gh-pages`)
  - Settings UI at `/:owner/:repo/settings/pages` + manual redeploy
- **C4** — Environments with protected approvals → ✅ shipped
  - Per-repo `environments` with reviewer list + branch-glob allowlist
  - Auto-deploy on main is gated by `requiresApprovalFor()`; pending rows show status `pending_approval`
  - Approve/reject at `POST /:owner/:repo/deployments/:id/approve|reject`

### BLOCK D — AI-native differentiation
This is where GlueCron beats GitHub outright. **Priority: ship these loud.**
- **D1** — Semantic code search → ✅ shipped. `src/lib/semantic-search.ts` + `src/routes/semantic-search.tsx`. `code_chunks` table stores chunk embeddings as JSON (upgrade path to `pgvector`). Embedding provider: Voyage AI `voyage-code-3` when `VOYAGE_API_KEY` is set, otherwise deterministic 512-dim hashing fallback. Index via `POST /:owner/:repo/search/semantic/reindex` (owner-only).
- **D2** — AI dependency updater → ✅ shipped. `src/lib/dep-updater.ts` + `src/routes/dep-updater.tsx`. `dep_update_runs` table tracks run history. Parses `package.json`, queries `registry.npmjs.org`, plans bumps (skips workspace/github specs + downgrades), writes an `gluecron/dep-update-<ts>` branch via git plumbing (`hash-object` + `mktree` + `commit-tree` + `update-ref`), inserts a pull_requests row with a markdown bump table. Settings UI at `/:owner/:repo/settings/dep-updater` with "Run now".
- **D3** — AI PR triage → ✅ shipped. `triagePullRequest` in `src/lib/ai-generators.ts`; hooked into PR create in `src/routes/pulls.tsx` (fire-and-forget). Posts a non-applied "## AI Triage" comment with suggested labels, reviewers, priority, and risk area. Suggestions only — PR author stays in control.
- **D4** — AI incident responder → ✅ shipped. `src/lib/ai-incident.ts` exports `onDeployFailure(args)` — on deploy-fail hooks, samples ~10 recent commits, calls Sonnet 4 for a structured root-cause JSON, opens an issue (number via `serial`), best-effort attaches `incident` label, sets `deployments.blockedReason="auto-issue #N"`. Wired from `src/hooks/post-receive.ts triggerCrontechDeploy` (fire-and-forget) and from `POST /:owner/:repo/deployments/:id/retry-incident` (owner-only re-run button on the deployment detail page). Never throws; degrades to deterministic body when no `ANTHROPIC_API_KEY`.
- **D5** — AI code reviewer blocks merges → ✅ shipped. `src/lib/branch-protection.ts` exports `matchProtection(repoId, branch)` (exact > glob, reuses `matchGlob` from environments.ts), `evaluateProtection(rule, ctx)` pure decision helper (checks `requireAiApproval` / `requireGreenGates` / `requireHumanReview` / `requiredApprovals`), and `countHumanApprovals(prId)` (LGTM/`+1`/approved heuristic on non-AI PR comments). Wired into `src/routes/pulls.tsx` merge handler after the existing hard-gate filter — blocks merge with readable reasons when rule fails. 8 unit tests in `src/__tests__/branch-protection.test.ts`.
- **D6** — AI "explain this codebase" → ✅ shipped. `src/lib/ai-explain.ts` + `src/routes/ai-explain.tsx`. Samples up to ~25 representative files (~60KB cap), generates a Markdown explanation via Sonnet 4, caches per (repo, commit sha) in `codebase_explanations`. `GET /:owner/:repo/explain` + owner-only `POST /:owner/:repo/explain/regenerate`. Explain link added to `RepoNav`.
- **D7** — AI changelog for every commit range → ✅ shipped. `src/routes/ai-changelog.tsx`. `GET /:owner/:repo/ai/changelog?from=&to=(&format=markdown)` — runs `git log` on the range, calls existing `generateChangelog`, renders form + rendered Markdown + copy-box; `format=markdown` returns `text/markdown` for CLI/CI consumers. Caps at 500 commits.
- **D8** — AI-generated test suite → ✅ shipped. `src/lib/ai-tests.ts` exports `detectLanguage(path)`, `detectTestFramework(repo tree)`, `buildTestsPrompt(...)`, `suggestedTestPath(...)`, `generateTestStub({path, content, framework, language})` (returns `{code:"", framework:"fallback"}` when AI unavailable), `contentTypeFor(path)`. Route `src/routes/ai-tests.tsx` adds `GET /:owner/:repo/ai/tests` (form + file picker), `GET /:owner/:repo/ai/tests?format=raw` (raw text with correct MIME), `POST /:owner/:repo/ai/tests/generate` (requireAuth, renders highlighted source + generated failing test, copy button). Stubs are intentionally failing so the author fills them in.
- **D9** — Copilot-style completion endpoint → ✅ shipped. `src/lib/ai-completion.ts` + `src/routes/copilot.ts`. `POST /api/copilot/completions` (requireAuth accepts PAT/OAuth/session), `GET /api/copilot/ping`. Claude Haiku; in-memory LRU (size 200, 5-min TTL); code-fence stripping; 60/min rate limit per caller.

### BLOCK E — Collaboration parity
- **E1** — Projects / kanban boards → ✅ shipped. `src/routes/projects.tsx`, tables `projects`/`project_columns`/`project_items` (migration 0015). Create creates three default columns (To Do/In Progress/Done); cards carry note or issue/pr link; one-click move between columns; owner-only close.
- **E2** — Discussions (forum threads per repo) → ✅ shipped. `src/routes/discussions.tsx`, tables `discussions`/`discussion_comments` (migration 0013). Categorised (general/q-and-a/ideas/announcements/show-and-tell), pinnable, lockable, q-and-a answers.
- **E3** — Wikis → ✅ shipped as DB-backed v1. `src/routes/wikis.tsx`, tables `wiki_pages`/`wiki_revisions` (migration 0016). Slug auto-derived; every edit bumps revision + appends a revision row; owner can revert. Git-backed mirror deferred.
- **E4** — Gists → ✅ shipped. `src/routes/gists.tsx`, tables `gists`/`gist_files`/`gist_revisions`/`gist_stars` (migration 0014). Multi-file; each edit takes a JSON snapshot into `gist_revisions` keyed on revision number; stars toggle; secret gists hidden from non-owners.
- **E5** — Merge queues → ✅ shipped. `src/lib/merge-queue.ts`, `src/routes/merge-queue.tsx`, table `merge_queue_entries` (migration 0017). Per `(repo, base_branch)` FIFO queue; `POST /:owner/:repo/pulls/:n/enqueue` adds from the PR page; owner-only `POST /queue/process-next` re-runs gates against latest base before merging the head. Entries have queued | running | merged | failed | dequeued states.
- **E6** — Required status checks matrix → ✅ shipped. `src/routes/required-checks.tsx`, table `branch_required_checks` (migration 0018); helpers `listRequiredChecks` + `passingCheckNames` in `src/lib/branch-protection.ts`. Settings UI at `/:owner/:repo/gates/protection/:id/checks`; merge handler (`src/routes/pulls.tsx`) loads required names + computes passing set from `gate_runs` (passed/repaired) + `workflow_runs` (success) and blocks if any required name is missing.
- **E7** — Protected tags → ✅ shipped. `src/lib/protected-tags.ts`, `src/routes/protected-tags.tsx`, table `protected_tags` (migration 0019). Settings CRUD at `/:owner/:repo/settings/protected-tags`; patterns use same glob syntax as branch protection. v1 enforcement is advisory: post-receive logs audit entries (`protected_tags.{create|update|delete}_violation_candidate`) so owners can see violations; pre-receive blocking is future work.

### BLOCK F — Observability + admin
- **F1** — Traffic analytics per repo → ✅ shipped. `src/lib/traffic.ts` + `src/routes/traffic.tsx`, table `repo_traffic_events` (migration 0020). `track`/`trackView`/`trackClone`/`trackByName` are fire-and-forget; SHA-256 of IP truncated to 16 chars for unique-visitor approximation. Owner-only `GET /:owner/:repo/traffic` renders 7/14/30/90 day windows with an ascii-bar daily chart. Wired into `src/routes/web.tsx` repo overview + `src/routes/git.ts` git-upload-pack handler.
- **F2** — Org-wide insights → ✅ shipped. `src/routes/org-insights.tsx` exports `computeOrgInsights(orgId)`. `GET /orgs/:slug/insights` requires org membership; aggregates gate green-rate, open/merged PR counts, open issue count, and per-repo rows sorted by activity. No new tables — live rollup across existing `repositories`, `gate_runs`, `pull_requests`, `issues`.
- **F3** — Admin / superuser panel → ✅ shipped. `src/lib/admin.ts` + `src/routes/admin.tsx`, tables `site_admins` + `system_flags` (migration 0020). `isSiteAdmin(userId)` with bootstrap rule (empty `site_admins` table → oldest user wins); `KNOWN_FLAGS` = { registration_locked, site_banner_text, site_banner_level, read_only_mode }. Routes: `GET /admin` (dashboard), `GET /admin/users` + toggle grant/revoke, `GET /admin/repos` + nuclear delete, `GET /admin/flags` + save. All mutations audit-logged.
- **F4** — Billing + quotas → ✅ shipped. `src/lib/billing.ts` + `src/routes/billing.tsx`, tables `billing_plans` + `user_quotas` (migration 0020, seeded with free/pro/team/enterprise). `FALLBACK_PLANS` mirror the seeds so billing works pre-migration. Helpers: `getUserQuota` (auto-initialises free row on first read), `bumpUsage`, `checkQuota` (fail-open), `wouldExceedRepoLimit`, `resetIfCycleExpired`. Routes: `GET /settings/billing` (personal view with usage bars + plan cards), `GET /admin/billing` (site-admin plan override), `POST /admin/billing/:userId/plan`.

### BLOCK G — Mobile + client
- **G1** — PWA manifest + service worker → ✅ shipped. `src/routes/pwa.ts` serves `/manifest.webmanifest`, `/sw.js`, `/icon.svg`; `Layout` injects `<link rel="manifest">` + a tiny SW registration script. Service worker is network-first for HTML + skips `.git/`/`/api/`/`/login*` routes.
- **G2** — GraphQL API mirror of REST → ✅ shipped. `src/lib/graphql.ts` is a dependency-free recursive-descent parser + executor over a fixed schema (viewer, user, repository, search, rateLimit). `src/routes/graphql.ts` serves `POST /api/graphql` + a GraphiQL-lite explorer at `GET /api/graphql`. Queries only; writes stay on REST.
- **G3** — Official CLI (`gluecron`) → ✅ shipped. `cli/gluecron.ts` is a Bun-compilable single-file CLI. Commands: `login`, `whoami`, `repo ls/show/create`, `issues ls`, `gql`, `host`, `version`. Config in `~/.gluecron/config.json` (0600). Talks to the server via REST + GraphQL.
- **G4** — VS Code extension → ✅ shipped. `vscode-extension/` contains package.json + `src/extension.ts`. Commands: `gluecron.explainFile`, `gluecron.openOnWeb`, `gluecron.searchSemantic`, `gluecron.generateTests`. Detects Gluecron remotes via `git config remote.origin.url`. Settings: `gluecron.host` + `gluecron.token`.

### BLOCK I — Filling parity gaps
- **I1** — Archive / unarchive repository → ✅ shipped. `src/routes/repo-settings.tsx` archive/unarchive toggle (existing `repositories.is_archived` column). `RepoHeader` surfaces an "Archived" badge.
- **I2** — Template repositories → ✅ shipped. `drizzle/0022_repo_templates.sql` adds `is_template` column + partial index. `src/routes/templates.ts` serves `POST /:owner/:repo/use-template` (git clone --bare into caller's namespace, fresh `activity_feed` entry). Settings UI gains a "Mark as template" toggle. Public repo page renders a prominent "Use this template" CTA for non-owners.
- **I3** — Repository transfer → ✅ shipped. `drizzle/0022_repo_templates.sql` adds `repo_transfers` audit table. `src/routes/repo-settings.tsx` `POST /:owner/:repo/settings/transfer` (validate target user exists, reject name conflicts, update `owner_id`, log to `repo_transfers`).
- **I4** — Generic command palette → ✅ shipped. `src/views/layout.tsx` injects a Cmd+K palette with ~20 canonical destinations (Dashboard, Explore, Notifications, Ask AI, Create repo, Marketplace, Installed apps, Register app, Shortcuts, Settings, 2FA, Passkeys, PATs, Billing, Audit, Gists, GraphQL, Admin, Theme). Fuzzy-match, arrow-key navigation, Esc/backdrop to close.
- **I5** — Code scanning UI → ✅ shipped. `src/routes/code-scanning.tsx` `GET /:owner/:repo/security` aggregates `gate_runs` matching `%scan%`/`%security%` (last 100), computes latest-per-gate status, renders failed/repaired/total summary cards + per-scanner status list + recent-runs table. Private-repo visibility enforced. Zero new tables — pure surfacing layer.
- **I6** — Sponsors → ✅ shipped. `drizzle/0023_sponsors.sql` adds `sponsorship_tiers` (maintainer_id, name, monthly_cents, one_time_allowed, is_active) + `sponsorships` (sponsor_id, maintainer_id, tier_id, amount_cents, kind, note, is_public, cancelled_at). `src/routes/sponsors.tsx` serves public `/sponsors/:username` (tier cards + recent public sponsors join) + maintainer `/settings/sponsors` (tier CRUD, soft-retire via is_active=false, activity list). Payment rails deferred — v1 captures intent + thank-you notes.
- **I7** — Weekly email digest → ✅ shipped. `drizzle/0024_email_digest.sql` adds `users.notify_email_digest_weekly` + `last_digest_sent_at`. `src/lib/email-digest.ts` exposes `composeDigest`/`sendDigestForUser`/`sendDigestsToAll` (never-throws). Pulls notifications + failed/repaired gate_runs + merged PRs from the last 7d, composes escaped HTML + plaintext, and sends via the shared email provider. `/settings/digest/preview` renders the digest inline for self-preview; `/admin/digests` gives site admins a "Send now" trigger + single-user preview, audit-logged as `admin.digests.run`/`admin.digests.preview`.
- **I8** — Symbol / xref navigation → ✅ shipped. `drizzle/0025_code_symbols.sql` adds a `code_symbols` table. `src/lib/symbols.ts` provides a regex-based top-level extractor for ts/js/py/rs/go/rb/java/kt/swift. On-demand indexing via `POST /:owner/:repo/symbols/reindex` walks the default-branch tree, caps at 2000 files/1MB each, replaces the prior set. Browse at `/:owner/:repo/symbols` (A–Z + per-kind counts), search via `/symbols/search?q=`, inspect at `/symbols/:name`. 14 new tests.
- **I9** — Repository mirroring → ✅ shipped. `drizzle/0026_repo_mirrors.sql` adds `repo_mirrors` (one-per-repo config) + `repo_mirror_runs` (audit log). `src/lib/mirrors.ts` provides URL validation (https/http/git only, no ssh/file/paths/shell metas), credentials-redaction for logs, and `runMirrorSync` that shells out to `git fetch --prune --tags` with a 5-min timeout and `GIT_TERMINAL_PROMPT=0`. `src/routes/mirrors.tsx` serves owner-only `/:owner/:repo/settings/mirror` + site-admin `/admin/mirrors/sync-all`. 17 new tests.
- **I10** — Enterprise SSO via OIDC → ✅ shipped. `drizzle/0027_sso_oidc.sql` adds `sso_config` (singleton `id='default'` row with issuer + authorize/token/userinfo endpoints + client credentials + scopes + optional email-domain allow-list + `auto_create_users` toggle) and `sso_user_links` (maps local user to IdP `sub`, unique per-subject). `src/lib/sso.ts` exposes `buildAuthorizeUrl`/`exchangeCode`/`fetchUserinfo`/`findOrCreateUserFromSso` pure helpers — plain OIDC auth-code flow, no XML / no signature verification dep. `src/routes/sso.tsx` serves site-admin `/admin/sso` config page, `/login/sso` initiator (state + nonce cookies, 10-min TTL), `/login/sso/callback` exchanger + session issuer, plus `POST /settings/sso/unlink` for users. `/login` renders "Sign in with &lt;provider name&gt;" when enabled. 24 new tests (pure helpers + route-auth smokes).

### BLOCK J — Beyond-parity advanced features
- **J1** — Dependency graph → ✅ shipped. `drizzle/0028_repo_dependencies.sql` adds `repo_dependencies` (ecosystem + name + version_spec + manifest_path + is_dev + commit_sha) with indexes on `(repository_id, ecosystem)` + `(name)`. `src/lib/deps.ts` parses seven manifest formats (package.json, requirements.txt, pyproject.toml, go.mod, Cargo.toml, Gemfile, composer.json) without a TOML library — each parser is defensive and returns `[]` on malformed input. Walks default-branch tree (max 200 manifests, 1MB each), replaces the prior set on reindex. `src/routes/deps.tsx` serves `/:owner/:repo/dependencies` (grouped by ecosystem with per-ecosystem counts) + owner-only `POST /dependencies/reindex`. Reverse-dep lookup via `repositoriesDependingOn(ecosystem, name)` for future "who depends on me" network-graph UI. 21 new tests.
- **J2** — Security advisories (Dependabot-style) → ✅ shipped. `drizzle/0029_security_advisories.sql` adds `security_advisories` (GHSA + CVE IDs, severity, affected range, fixed version) + `repo_advisory_alerts` (per-repo match state with open/dismissed/fixed, unique on `(repo, advisory, manifest_path)`). `src/lib/advisories.ts` ships a 12-entry seed list (log4shell, lodash, minimist, vm2, urllib3, jwt-go, etc.), a minimal version-range matcher (`satisfiesRange` + `rangeMatches`) that handles `<`/`<=`/`>`/`>=`/`=` clauses including compound ranges, and `scanRepositoryForAlerts(repoId)` which cross-references J1 dep rows against the advisory list — inserts new alerts, reopens fixed-then-regressed ones, auto-closes alerts whose dep went away. `src/routes/advisories.tsx` serves `/:owner/:repo/security/advisories` (open), `/all` (everything), owner-only `POST /scan`, and per-alert `POST /:id/dismiss` + `POST /:id/reopen` with audit-log entries. 27 new tests (version parser, range matcher, seed shape, route auth).
- **J3** — Commit signature verification (GPG + SSH "Verified" badge) → ✅ shipped. `drizzle/0030_signing_keys.sql` adds `signing_keys` (per-user GPG/SSH pubkeys, unique on `(key_type, fingerprint)`) + `commit_verifications` (memoised per-commit result, unique on `(repo, sha)`). `src/lib/signatures.ts` extracts `gpgsig` / `gpgsig-sha256` from raw commit objects (`getRawCommitObject` added to `src/git/repository.ts`), unarmors PGP + SSH signature blobs, walks OpenPGP packet streams for Issuer Fingerprint (subpacket 33) / Issuer Key ID (subpacket 16), parses the SSHSIG inner publickey field, and SHA-256 fingerprints SSH wire-format keys. Identity matching via fingerprint → optional email check → cached. `src/routes/signing-keys.tsx` serves `GET/POST /settings/signing-keys` + `POST /settings/signing-keys/:id/delete`, audit-logged. `CommitList` + single commit view render a green "Verified" badge when cached `verified=true`. 29 new tests (extraction, unarmor, packet walker, SSH fp, end-to-end fast paths, route auth).
- **J4** — User following + personalised feed → ✅ shipped. `drizzle/0031_user_follows.sql` adds `user_follows` (composite PK on `(follower_id, following_id)`, CHECK constraint rejecting self-follows, reverse-lookup index on `following_id`). `src/lib/follows.ts` exposes `followUser/unfollowUser/isFollowing/listFollowers/listFollowing/followCounts` + `feedForUser(userId, limit)` which joins `activity_feed` against the follow set (bounded to 200 edges) and filters out private repos the viewer doesn't own. `src/routes/follows.tsx` serves `POST /:user/follow` + `/:user/unfollow` (auth-gated, audit-logged), public `GET /:user/followers` + `/:user/following`, and `GET /feed` (personalised timeline). Follow button + follower/following counts added to the user profile page via `src/routes/web.tsx`. Reserved-name set protects fixed paths (`login`, `settings`, `feed`, etc.). 8 new tests (verb table + route auth).
- **J5** — Profile READMEs → ✅ shipped. User profile page at `/:owner` now attempts to render `<user>/<user>/README.md` (GitHub convention) or `<user>/.github/README.md` (org-style fallback) as the hero panel above the repo list. No schema changes — reuses `getReadme` / `renderMarkdown` + `repoExists` from the git layer. Failures are silent; missing repo just hides the panel. 2 smoke tests.
- **J6** — Repository rulesets (push policy engine) → ✅ shipped. `drizzle/0032_repo_rulesets.sql` adds `repo_rulesets` (unique on `(repository_id, name)`, enforcement enum active/evaluate/disabled) + `ruleset_rules` (JSON params). `src/lib/rulesets.ts` exposes six rule types (`commit_message_pattern`, `branch_name_pattern`, `tag_name_pattern`, `blocked_file_paths`, `max_file_size`, `forbid_force_push`) + the pure evaluator `evaluatePush(rulesets, ctx) → {allowed, violations}`. Helpers: glob-lite matcher (`globToRegex`), defensive `parseParams`. CRUD: `listRulesetsForRepo`, `getRuleset`, `createRuleset`, `updateRulesetEnforcement`, `deleteRuleset`, `addRule`, `deleteRule`. `src/routes/rulesets.tsx` serves owner-only UI at `/:owner/:repo/settings/rulesets` (list + create), `/:id` (detail, enforcement toggle, add rule), `/:id/delete`, `/:id/rules/:ruleId/delete`. 23 new tests covering each rule type, enforcement modes, glob edge cases, and route-auth redirects.
- **J7** — Closing keywords auto-close issues on PR merge → ✅ shipped. `src/lib/close-keywords.ts` exports pure `extractClosingRefs(text)` and `extractClosingRefsMulti(sources[])` — scans for `(close|closes|closed|fix|fixes|fixed|resolve|resolves|resolved)[:|-]? #N` with case-insensitive, punctuation-tolerant, word-boundary-respecting matching. Rejects cross-repo refs (`owner/repo#N`), embedded-in-word verbs (`disclose`, `unresolved`), and non-positive numbers. Wired into the PR merge handler in `src/routes/pulls.tsx` — after a successful merge, scans `pr.title + pr.body`, looks up each referenced open issue in the same repo, closes it, and posts a "Closed by pull request #N" comment. Wrapped in try/catch so close-keyword failures never block the merge redirect. 14 new tests covering verb forms, punctuation variants, de-dup+sort, cross-repo rejection, embedded-word rejection, case-insensitivity, and multi-source merging. Total suite 749/749.
- **J8** — Commit status API (external CI signals) → ✅ shipped. `drizzle/0033_commit_statuses.sql` adds `commit_statuses` (unique on `(repository_id, commit_sha, context)`, state vocabulary pending/success/failure/error). `src/lib/commit-statuses.ts` exposes pure helpers (`isValidSha`, `isValidState`, `sanitiseContext`, `reduceCombined`) and DB helpers (`setStatus` with delete-then-insert upsert, `listStatuses`, `combinedStatus`). `src/routes/commit-statuses.ts` serves `POST /api/v1/repos/:owner/:repo/statuses/:sha` (requireAuth + owner check), `GET /api/v1/repos/:owner/:repo/commits/:sha/statuses` (list, private-repo visibility), `GET /api/v1/repos/:owner/:repo/commits/:sha/status` (combined rollup). Commit detail view now renders a "Checks" pill row when statuses exist, colour-coded per state with clickable target URLs. 18 new tests covering the pure helpers + route auth + invalid-sha rejection. Total suite 767/767.

### BLOCK H — Marketplace
- **H1** — App marketplace → ✅ shipped. `src/routes/marketplace.tsx` + `src/lib/marketplace.ts` + `drizzle/0021_marketplace_and_apps.sql` (5 tables: `apps`, `app_installations`, `app_bots`, `app_install_tokens`, `app_events`). Routes: `GET /marketplace` (public directory with search), `GET /marketplace/:slug` (detail + install CTA), `POST /marketplace/:slug/install` (user-target install in v1), `POST /marketplace/installations/:id/uninstall`, `GET /settings/apps` (personal list), `GET+POST /developer/apps-new` (register), `GET /developer/apps/:slug/manage` (event log + install count), `POST /developer/apps/:slug/tokens/new` (show-once token). Install idempotent via soft-update on existing non-uninstalled row.
- **H2** — GitHub Apps equivalent (bot identities + installation tokens) → ✅ shipped. Same schema as H1: every app gets a `<slug>[bot]` row in `app_bots`. `generateBearerToken()` produces `ghi_`-prefixed bearers; `hashBearer` (sha256) is the only form persisted. `verifyInstallToken(token)` returns `{installation, app, botUsername, permissions}` or `null` (checks revoked/expired/uninstalled/suspended). Permission vocabulary: `contents:read/write`, `issues:read/write`, `pulls:read/write`, `checks:read/write`, `deployments:read/write`, `metadata:read` — `hasPermission` implements write→read implication.

- `src/lib/packages.ts` (Block C2) — npm protocol helpers: `parsePackageName`, `computeShasum` (sha1), `computeIntegrity` (sha512 base64), `buildPackument`, `resolveRepoFromPackageJson`, `parseRepoUrl`, `tarballFilename`. Pure functions.
- `src/lib/pages.ts` (Block C3) — `onPagesPush` (never throws), `resolvePagesPath` (probe list including pretty URLs + traversal strip), `contentTypeFor` (MIME).
- `src/lib/environments.ts` (Block C4) — `matchGlob`, `listEnvironments`, `getOrCreateEnvironment`, `getEnvironmentByName`, `isReviewer`, `reviewerIdsOf`, `allowedBranchesOf`, `computeApprovalState`, `reduceApprovalState`, `recordApproval`, `requiresApprovalFor`. Empty reviewers list → repo owner approves. Any rejection hard-stops.

### 4.4 AI layer (locked)

PR page has an extra "Add to merge queue" button.
- `src/lib/merge-queue.ts` (Block E5) — `enqueuePr`, `dequeueEntry`, `peekHead`, `markHeadRunning`, `completeEntry`, `isQueued`, `queueDepth`, `listQueue`, `listQueueWithPrs`. No side effects beyond the `merge_queue_entries` table; callers own gate execution + git updates.
- `src/routes/required-checks.tsx` (Block E6) — `/:owner/:repo/gates/protection/:id/checks` CRUD (owner-only, requireAuth). "Required checks" link added on gates settings UI next to each branch protection rule.
- `src/lib/branch-protection.ts` extends for E6 — `listRequiredChecks(branchProtectionId)`, `passingCheckNames(repositoryId, commitSha)` (scans `gate_runs` + `workflow_runs`), and `evaluateProtection(rule, ctx, requiredChecks[])` now takes a third param + reports `missingChecks`.
- `src/routes/protected-tags.tsx` (Block E7) — `/:owner/:repo/settings/protected-tags` CRUD (owner-only, requireAuth).

- `src/routes/org-insights.tsx` (Block F2) — exports `computeOrgInsights(orgId)` returning `OrgInsightsSummary` (repoCount, gateRunsTotal, greenRate, openIssues, openPrs, mergedPrs30d, perRepo[]). `GET /orgs/:slug/insights` requires org membership. No new tables.
- `src/lib/admin.ts` (Block F3) — `isSiteAdmin(userId)` with bootstrap rule (empty `site_admins` → oldest user wins), `listSiteAdmins`, `grantSiteAdmin`, `revokeSiteAdmin`, `getFlag`, `setFlag`, `listFlags`, `KNOWN_FLAGS = { registration_locked, site_banner_text, site_banner_level, read_only_mode }`. All helpers swallow DB errors.
- `src/routes/admin.tsx` (Block F3) — `GET /admin` dashboard (user/repo/admin counts + recent signups), `/admin/users` + toggle grant/revoke, `/admin/repos` + nuclear delete, `/admin/flags` form. All mutations audit-logged via `audit()`. Gated through a `gate(c)` helper that returns `{user} | Response`.
- `src/lib/billing.ts` (Block F4) — plan + quota helpers. `FALLBACK_PLANS` (free/pro/team/enterprise) mirror the seed rows. `getUserQuota(userId)` auto-initialises free row. `bumpUsage`, `checkQuota` (fail-open), `wouldExceedRepoLimit`, `resetIfCycleExpired`, `formatPrice`. Never throws into request path.
- `src/routes/billing.tsx` (Block F4) — `GET /settings/billing` (personal view with usage bars + plan cards), `GET /admin/billing` (site-admin user/plan table), `POST /admin/billing/:userId/plan` (override plan, audit-logged).

- `src/lib/graphql.ts` (Block G2) — hand-rolled recursive-descent parser (`parseQuery`) + executor (`execute`) over a fixed schema. Zero dependencies. Root fields: viewer, user, repository, search, rateLimit. No mutations.
- `src/routes/graphql.ts` (Block G2) — `POST /api/graphql` JSON endpoint + `GET /api/graphql` GraphiQL-lite explorer (Cmd+Enter to run).
- `cli/gluecron.ts` (Block G3) — single-file Bun CLI. Exports `dispatch(argv, out)` for programmatic use, `HELP` constant, `loadConfig`/`saveConfig`. Config at `~/.gluecron/config.json` (0600). Compile: `bun build cli/gluecron.ts --compile --outfile gluecron`.
- `vscode-extension/` (Block G4) — VS Code extension with `package.json` declaring four commands (explainFile, openOnWeb, searchSemantic, generateTests) + `gluecron.host` / `gluecron.token` settings. Detects Gluecron remotes via `git config remote.origin.url`.
- `src/lib/marketplace.ts` (Block H1+H2) — marketplace + app identity surface. `KNOWN_PERMISSIONS` (10 scopes), `KNOWN_EVENTS` (8 kinds). Pure helpers: `slugify` (40-char cap), `botUsername` (`<slug>[bot]`), `normalisePermissions` (drops unknown, de-dupes), `parsePermissions` (JSON), `hasPermission` (write→read implication), `permissionsSubset`, `generateBearerToken` (`ghi_` prefix + 24-byte hex), `hashBearer` (sha256). DB helpers: `listPublicApps(query)`, `getAppBySlug`, `createApp` (retries slug collisions, creates matching bot row), `installApp` (idempotent soft-update), `uninstallApp` (revokes all tokens), `issueInstallToken` (1h TTL default), `verifyInstallToken` (checks revoked/expired/uninstalled/suspended), `listInstallationsForApp`, `listInstallationsForTarget`, `listEventsForApp`, `countInstalls`. Never throws into request path.
- `src/routes/marketplace.tsx` (Block H1+H2) — public marketplace + developer UX. `GET /marketplace` (directory + search), `GET /marketplace/:slug` (detail + install form), `POST /marketplace/:slug/install` (v1 user-target only), `POST /marketplace/installations/:id/uninstall` (installer-only), `GET /settings/apps` (personal list), `GET+POST /developer/apps-new` (register), `GET /developer/apps/:slug/manage` (event log + install count, owner-only), `POST /developer/apps/:slug/tokens/new` (show-once `ghi_` token). All mutations audit-logged.
- `src/routes/code-scanning.tsx` (Block I5) — `GET /:owner/:repo/security` (softAuth, private-repo visibility enforced). Aggregates last-100 scan-related `gate_runs`, builds `latestByName` map, renders summary cards + scanner status list + recent runs.
- `src/routes/sponsors.tsx` (Block I6) — public `/sponsors/:username` + maintainer `/settings/sponsors` (requireAuth). Tier CRUD (`POST /settings/sponsors/tiers/new`, soft-retire via `is_active=false` on delete). Exports `sponsorshipTotalForUser(userId)` helper and `__internal.formatCents` for tests.
- `src/lib/email-digest.ts` (Block I7) — `composeDigest(userId, since?)` (never throws, null on failure), `sendDigestForUser(userId)` (opt-out check + updates `last_digest_sent_at` on success), `sendDigestsToAll()` (iterates opted-in users). Pulls notifications + owned-repo gate_runs (failed/repaired) + merged PRs over last 7d. Builds text + escaped HTML body. Exports `__internal = { textToHtml, escapeHtml, fmtRange }` for tests.
- `src/routes/admin.tsx` (extends Block F3 for I7) — adds `GET /admin/digests` (opted-in count + recently sent list), `POST /admin/digests/run` (calls `sendDigestsToAll`, audit-logged with counts), `POST /admin/digests/preview` (sends to one user by username, audit-logged). New "Email digests" tile on the /admin dashboard grid.
- `src/routes/settings.tsx` (extends for I7) — adds `notify_email_digest_weekly` checkbox to email prefs + handler wiring in `POST /settings/notifications`, and `GET /settings/digest/preview` (renders `composeDigest` output inline via `raw(body.html)` with Hono's `hono/html`).
- `src/lib/symbols.ts` (Block I8) — regex-based top-level symbol extractor. Pure helpers: `detectLanguage(path)` (10 extensions mapped to 8 languages), `extractSymbols(content, lang)` (per-language rule list, 1-based line numbers, 240-char signature cap, skips lines >500 chars). `indexRepositorySymbols(repoId)` walks the default-branch tree, caps at 2000 files / 1MB each, replaces the prior set in batches of 500. `findDefinitions(repoId, name)` + `countSymbolsForRepo(repoId)`. `__internal` exposes `RULES` + `EXT_LANG` for tests.
- `src/routes/symbols.tsx` (Block I8) — `/:owner/:repo/symbols` overview (total + per-kind counts + A–Z list with blob deep-links), `/:owner/:repo/symbols/search?q=` prefix search (ilike `q%`), `/:owner/:repo/symbols/:name` detail (all definitions with signature preview + deep link). `POST /:owner/:repo/symbols/reindex` is requireAuth + owner-only.
- `src/lib/mirrors.ts` (Block I9) — upstream URL validator (accepts https/http/git schemes, rejects ssh/file/paths/shell metacharacters, 2048-char cap), `safeUrlForLog` (redacts embedded credentials), `upsertMirror` / `deleteMirror` / `getMirrorForRepo` / `listRecentRuns`, `runMirrorSync` (runs `git fetch --prune --tags --no-write-fetch-head` via `Bun.spawn` with 5-min timeout + `GIT_TERMINAL_PROMPT=0`; updates `last_synced_at` + `last_status` + `last_error`), `listDueMirrors` + `syncAllDue` for the admin trigger.
- `src/routes/mirrors.tsx` (Block I9) — owner-only config at `/:owner/:repo/settings/mirror` (GET form + recent-runs panel, POST save, POST delete, POST sync-now). Site-admin `POST /admin/mirrors/sync-all` iterates due mirrors. All mutations `audit()`-logged.
- `src/lib/rulesets.ts` (Block J6) — exports `RULE_TYPES` (6 types), pure `globToRegex`, defensive `parseParams`, pure evaluator `evaluatePush(rulesets, ctx) → {allowed, violations}`. CRUD: `listRulesetsForRepo`, `getRuleset`, `createRuleset`, `updateRulesetEnforcement`, `deleteRuleset`, `addRule`, `deleteRule`. `__internal = { evalRule, globToRegex, parseParams }` for tests. Every rule variant no-ops on malformed params or bad regex rather than throwing.
- `src/routes/rulesets.tsx` (Block J6) — owner-only UI at `/:owner/:repo/settings/rulesets` (list + create), `/:id` (detail + enforcement toggle + add rule), `/:id/delete`, `/:id/rules/:ruleId/delete`. All mutations `audit()`-logged via the existing `gate(c)` owner pattern.
- `src/lib/close-keywords.ts` (Block J7) — pure parser. Exports `extractClosingRefs(text)` + `extractClosingRefsMulti(sources[])`. Verbs: close/closes/closed/fix/fixes/fixed/resolve/resolves/resolved. Case-insensitive, word-boundary-respecting, ignores cross-repo `owner/repo#N` refs, rejects non-positive numbers, returns sorted de-duped list. Tolerates `:` / `-` / whitespace between verb and ref.
- `src/lib/commit-statuses.ts` (Block J8) — pure helpers: `isValidSha`, `isValidState`, `sanitiseContext`, `reduceCombined`. DB helpers: `setStatus` (delete-then-insert upsert on `(repo, sha, context)`, SHA lowercased, description/url clamped to 1000/2048 chars), `listStatuses` (newest first), `combinedStatus` (latest per context, reduces to worst state, returns counts + context pills). `STATUS_STATES` exported array. Never throws on clamping; null/empty description returns null.
- `src/routes/commit-statuses.ts` (Block J8) — `POST /api/v1/repos/:owner/:repo/statuses/:sha` (requireAuth — accepts session/OAuth/PAT; owner-only), `GET /api/v1/repos/:owner/:repo/commits/:sha/statuses` (softAuth, private-repo visibility enforced), `GET /api/v1/repos/:owner/:repo/commits/:sha/status` (combined rollup, same visibility rules).

### 4.7 Views (locked contracts)
- `src/views/layout.tsx` — `Layout` accepts `title`, `user`, `notificationCount`
- `src/views/components.tsx` — `RepoHeader`, `RepoNav` (active: `code|issues|pulls|commits|releases|actions|gates|insights|explain|changelog|semantic`), `RepoCard`, etc.
- `src/views/reactions.tsx` — `ReactionsBar` (no-JS compatible, form-per-emoji)
- Nav links: logo · search · theme-toggle · Explore · Ask · Notifications · New · Profile (or Sign in / Register)
- Keyboard chords: `/`, `Cmd+K`, `?`, `n`, `g d`, `g n`, `g e`, `g a`

### 4.8 Tests (locked)
- `src/__tests__/green-ecosystem.test.ts` — secret scanner, codeowners, AI fallback, health, rate-limit headers, `/shortcuts`, `/search`
- All other existing test files — do not delete without owner permission

### 4.9 Invariants (never break these)
- `isAiAvailable()` guard returns true fallback strings when no ANTHROPIC_API_KEY. AI features degrade gracefully.
- `getUnreadCount` never throws; returns 0 on any error.
- Rate-limit middleware adds `X-RateLimit-Limit` + `X-RateLimit-Remaining` to every response, including 500s.
- `c.header("X-Request-Id", ...)` set by request-context on every response.
- Secret scanner skips binary/lock paths (`shouldSkipPath`).
- `SECRET_PATTERNS` is an exported array. Its shape is `{ type, regex, severity }`.
- Theme routes live outside `/settings/*` (they must work for logged-out visitors). Cookie name: `theme`, values: `dark|light`.
- Draft PRs cannot be merged — `/pulls/:n/merge` returns a redirect with the draft error when `pr.isDraft=true`.
- Reactions API accepts only `ALLOWED_EMOJIS` and `ALLOWED_TARGETS`. Toggle is idempotent per (user, target, emoji).
- `sendEmail()` never throws — always resolves to `{ ok, provider, ... }`. Email failures never break notification delivery or the primary request path.
- Email fan-out in `notify()` is scoped to kinds in `EMAIL_ELIGIBLE` (mention / review_requested / assigned / gate_failed). Each eligible kind maps to exactly one user preference column.
- Issue + PR template loading must return `null` on any git-subprocess failure (templates are a convenience, not a requirement). Forms always render.

1. Read this file, `CLAUDE.md`, `README.md`, `git log -1 --stat`.
2. Check `git status` + current branch.
3. Pick the next unfinished block from §3 (lowest letter + number first, unless owner specifies).
4. Create a todo list that mirrors the sub-items of that block.
5. Build. Write tests. Run `bun test`.
6. Commit with `feat(<BLOCK-ID>): ...`.
7. Push.
8. Update this file:
   - Move the block's row in §2 to ✅ where applicable.
   - Add the block's files to §4 LOCKED BLOCKS.
   - Commit + push again.
9. Start the next block. **Do not stop to ask.**

If a block is too large for a single session, split it into a sub-plan at the top of the session, ship what you can, and document what's left at the end of this file under a `## 7. IN-FLIGHT` section.

## 7. IN-FLIGHT

(Intentionally empty. Add here if a block is partially complete at session end.)
