# Plan — Phase 1 Automated Publishing Engine (with LinkedIn MCP Server)

**Revision:** v2 (consolidated from 7-agent BMAD panel review 2026-04-19)
**Verdicts file:** `/tmp/bmad-panel-verdicts-publishing-engine-phase1-20260419.json` (WSL)
**Panel result:** 1 APPROVE, 6 REVISE, 0 REJECT — all principles ≥3 (gate passes). Revisions below address each REVISE gap, citing originating agent.

**Applicability:** tier-2 = [RBR, A11y, Testability]
**Precedence:** `CLAUDE.md > Conflict Resolution Precedence` + adopted doctrine at `/home/devuser/projects/dqms/.clinerules/12-foundational-principles.md` (user directive 2026-04-19)

---

## 1. Context

User directive 2026-04-19: **Full Phase 1 automation, now.** No manual posting, no postponing. LinkedIn programmatic refresh is gated to MDP partners per [Microsoft Learn > Programmatic Refresh Tokens (retrieved 2026-04-19)](https://learn.microsoft.com/en-us/linkedin/shared/authentication/programmatic-refresh-tokens). Non-MDP apps must re-auth every ≤60 days; we accept this as the honest fallback and file MDP in parallel.

Existing state (verified 2026-04-19):
- `stargue-com` and `stargue-net` both on Next.js 16 + React 19 + Bun + Tailwind v4 + remark (verified against `package.json` per **dev** agent). Note: **stargue-net/package.json is a copy of stargue-com** (same `name` field) — **name collision to resolve before workspace linking** (dev gap 5).
- Listmonk email capture + CTA + content protection already shipped on stargue.com.
- Dokploy on `sg-paas-s1.stargue.net`; Gitea at `git.stargue.net`; OpenObserve observability stack.
- Stargue LinkedIn Company Page: `urn:li:organization:2605890` (user-confirmed 2026-04-19).
- Authentik SSO: user-confirmed running; all Stargue services share the same instance.

**Capacity reconciliation (PM/SM gap).** PRD §6.5 caps Angelo at 4h/week. The user has explicitly overridden this cap for this Phase 1 build — "no postponing, fully functional now." Plan is re-expressed below as **concentrated full-time build (14 calendar days)** with the user accepting timeline risk explicitly. If the user later reverts to the 4h/week cap, Stages 2–7 re-expand to ~15 weeks at 4h/week.

---

## 2. Objectives

1. **Automated two-channel publish pipeline** — Obsidian vault → stargue.com/.net (git push → Dokploy) + LinkedIn (personal profile `angeloluidens` + company page `urn:li:organization:2605890`) via a **Stargue LinkedIn MCP Server**.
2. **Optimized cadence** — bootstrap Tue + Thu 08:30 AM AST; adaptive refinement after data accrues (≥8 samples per (day,hour) slot), proposed-not-auto-applied.
3. **Fail-closed content sanitization** — wikilink/Obsidian strip + private-path blocklist + tag firewall + per-outlet length validation.
4. **Admin dashboard** — approval queue, side-by-side outlet preview, per-outlet status, scheduled-publish controls, metrics heatmap.
5. **PostgreSQL content registry** (PaaS) — SSoT for publication state, idempotency, audit; nightly pg_dump → Neon free tier for DR.
6. **OAuth 2.0 handled honestly** — 60-day re-auth fallback with proactive T-5-day notification + fail-safe halt; MDP app filed in parallel.
7. **Revenue conversion preserved** (PM gap). Phase 1 must not regress the already-shipped revenue surfaces on stargue.com (Listmonk email capture, CTAs, service page, Terms of Use). New inbound-inquiry tracking column on `publications.metadata_jsonb.inquiries` (counter incremented when a contact-page submission cites the post's slug as referrer).
8. **Kill-switch** — per-outlet feature flag (`OUTLET_ENABLED:linkedin=false`) readable at runtime without redeploy, toggled via admin dashboard. TEA gap 10.

---

## 3. Architecture

### 3.1 Repository topology (simplified per **architect** gap 1)

Collapsed `apps/api` into `apps/admin` Next.js App Router route handlers. Scheduler imports `linkedin-client` directly as a library; MCP transport is **stdio only** (for Claude Code use); HTTP transport deferred until a real cross-service need emerges (architect gap 2).

### 3.2 LinkedIn API — corrected per **dev** agent

**Endpoint (dev gap 3):** Posts API `https://api.linkedin.com/rest/posts` — NOT legacy `/v2/ugcPosts`. Required headers: `LinkedIn-Version: 202404` (or current YYYYMM per release cadence), `X-Restli-Protocol-Version: 2.0.0`, `Authorization: Bearer <access_token>`. Request shape uses flat `content` + `distribution` (not nested `specificContent/com.linkedin.ugc.ShareContent`).

**Auth flow (dev gap 2):** OAuth 2.0 Authorization Code flow — **no PKCE** (LinkedIn 3LO does not document PKCE support per [Microsoft Learn > 3-Legged OAuth Flow](https://learn.microsoft.com/en-us/linkedin/shared/authentication/authorization-code-flow), retrieved 2026-04-19). We use confidential-client with `client_secret` + CSRF-protected `state` parameter.

**Products required in LinkedIn Dev Portal (dev gap 1):**
| Product | Scopes granted | Purpose | Approval gate |
|---|---|---|---|
| **Sign In with LinkedIn using OpenID Connect** | `openid profile email` | Identity | Standard |
| **Share on LinkedIn** | `w_member_social` | Personal-profile posts | Standard |
| **Community Management API** | `w_organization_social`, `r_organization_social` | Company-page posts | **Requires LinkedIn partner approval — separate from MDP, non-trivial gate** |
| **Marketing Developer Platform (MDP)** — aspirational | Programmatic refresh tokens | Eliminate 60-day re-auth | Multi-week review |

**Impact:** Company Page posting (Objective 1, personal + `org:2605890`) may be blocked pending Community Management API approval. Personal-profile posting unblocked immediately. We file Community Management API application in Stage 0.5 and build the tools so they're ready when approved.

**Token store (architect gap 3):** Encryption primitive corrected to **libsodium `crypto_secretbox`** (symmetric XSalsa20-Poly1305) with a 32-byte key stored in Dokploy secrets. Sealed-box was wrong for at-rest DB encryption. Alternative considered: KMS envelope encryption via age-based encryption — deferred (no KMS in Stargue PaaS yet; secretbox+secret is adequate for Phase 1 blast radius).

**Refresh concurrency (TEA gap 3):** Token rotation path acquires a Postgres advisory lock keyed on `hashtextextended(subject_urn, 0)` before reading/refreshing. Lock released after commit. Prevents double-rotation race.

**Idempotency (dev gap 4, TEA gap 5):** `publications` table has `idempotency_key TEXT UNIQUE NOT NULL` populated as `sha256(content_id || outlet || scheduled_at)`. LinkedIn handler refuses to dispatch if a `publications` row with `external_id IS NOT NULL` already exists for the key. BullMQ jobs also carry an `idempotency_key` to dedupe retries before they reach the handler.

**Rate limits (architect gap 4).** LinkedIn does not publicly document a fixed per-member posting cap. We impose **self-imposed conservative limits** (not LinkedIn quota): 20 posts/day/member, 50 posts/day/org. Stage 3 DoD asserts this via a test (TEA gap 6).

**MCP tools exposed (stdio transport, no HTTP):**
| Tool | Purpose |
|---|---|
| `linkedin_whoami` | Returns authenticated subject + scopes + MDP-eligible flag |
| `linkedin_auth_status` | Access-expiry remaining, refresh-expiry remaining, kill-switch state |
| `linkedin_create_post` | Text post via Posts API (`author_urn` param: `urn:li:person:<id>` or `urn:li:organization:2605890`) |
| `linkedin_create_article` | Long-form article (≤125k chars) |
| `linkedin_upload_media` | Image / PDF carousel; returns asset URN |
| `linkedin_create_post_with_media` | Combines upload + post |
| `linkedin_delete_post` | Delete post by URN (soft-reversible within 5-min edit window only; after that, delete-only) |
| `linkedin_get_post_metrics` | Impressions/reactions/comments/shares/clicks for a URN |
| `linkedin_get_profile_stats` | Aggregate profile stats for cadence optimizer |

### 3.3 Sanitization pipeline

`packages/sanitize` — Unified/remark plugin chain:
1. Strip wikilinks `[[Path/Note|Display]]` → `Display` or plain removal.
2. Strip embeds `![[file]]` → resolve (blog) or remove (LinkedIn).
3. Strip dataview blocks.
4. Strip callouts.
5. **Private-path blocklist** — `Family Matters/`, `Financial Matters/`, `Journal/`, `Clients/*[NDA]/`, extensible. Match triggers **build error**, not silent strip.
6. **Tag firewall** — `#private`, `#heal-internal`, `#confidential` trigger build error.
7. Per-outlet length validation (LinkedIn 3k / article 125k / Twitter 280 / etc.).
8. Idempotency hash output (`content_hash`) over sanitized body for dedupe.

**Test corpus (SM gap 2, TEA gap 8):** `test/corpus/private/*` contains 12 fixture files — 4 blocklist-path, 4 tag-firewall, 4 length-overflow. Stage 1 DoD: **"CI passes when all 12 round-trip with build errors AND all reference clean files round-trip without errors."** Promoted from Risks to Stage 1 DoD.

### 3.4 Content registry (Postgres) + DR

Drizzle schema in `packages/schema/db.ts`:

- `content(id, vault_path, slug, title, body_sanitized, frontmatter_jsonb, content_hash, version, created_at, updated_at)`
- `publications(id, content_id, outlet, status, scheduled_at, published_at, external_id, external_url, idempotency_key UNIQUE, error, metadata_jsonb)`
- `approvals(id, content_id, outlet, approved_by, approved_at, notes)`
- `metrics(id, publication_id, collected_at, impressions, reactions, comments, shares, clicks, raw_jsonb)`
- `linkedin_tokens(id, subject_type, subject_urn, access_token_ct, refresh_token_ct, access_expires_at, refresh_expires_at, scopes, created_at, updated_at)`
- `audit(id, ts, actor, action, subject_type, subject_id, correlation_id, payload_jsonb)` — append-only
- `outlet_feature_flags(outlet, enabled, reason, updated_at, updated_by)` — kill-switch (Objective 8)

**Migrations (architect gap 7, TEA gap 4):** Every schema change follows **expand-then-contract**. Example for idempotency_key rollout: (1) add column nullable, (2) backfill via one-time script with SELECT … UPDATE … WHERE, (3) `NOT NULL` + `UNIQUE` constraint added in a second migration, (4) contract legacy column in a third migration once no code writes it. Each migration accompanied by a runbook in `db/migrations/README.md`. **Stage 2 DoD:** "Migration rehearsal on staging DB captures full expand→backfill→contract sequence with rollback point documented."

**DR mirror:** nightly cron runs `pg_dump --format=c` streamed to Neon free tier via Neon connection string in Dokploy secrets. Retains only last 30 days of metrics on the mirror (respects Neon 0.5 GB free cap). RPO ~24h.

### 3.5 Admin dashboard + A11y (UX gaps 1–8)

Next.js App Router. Authentik SSO (user-confirmed instance). Routes also host `/api/*` handlers (architect gap 1 collapse).

**Pages:**
- `/queue` — scheduled + pending items, side-by-side outlet preview, approval CTA
- `/publications/:id` — per-outlet status, metrics, errors
- `/auth/linkedin` — OAuth flow + re-auth link + kill-switch toggle
- `/metrics` — heatmap (day × hour × outlet)

**Nine Laws temperature declaration (UX gap 5):** Admin dashboard is an **operator tool**, not a reader surface. It inhabits the **cool / stargue.net (forge) temperature**. Forest-green (#4E8211) + Citrus (#99CC00) accents. **Amber (#F59E0B-family) reserved for Hearth content only — never leaks into admin status badges** (Law 4). Status badges use Forest/slate/red variants.

**A11y DoDs (UX gaps 1–4, 6–8; dev gap A11y; TEA gap 7):**
- Axe-core ruleset pinned to `axe-core@4.x`, severity gate: **zero `serious` or `critical` violations** on every route (SM gap 5).
- WCAG 2.2 AA contrast verification via script that reads design-token file, asserts each FG/BG pair ≥4.5:1 body and ≥3:1 large-text/non-text-UI on **both themes**.
- Screen-reader smoke test in CI: `@axe-core/playwright` + NVDA scripting via GitHub Actions on Windows runner for the approval flow; manual VoiceOver pass in release checklist.
- `aria-live="polite"` on queue status transitions; `aria-live="assertive"` on publish errors only. Announcement text specified per surface.
- Error association: every form input has `aria-describedby` → error-message container; WCAG 3.3.1/3.3.3/4.1.3 complied.
- Focus trap on modal approval confirmations; skip-link on dashboard; `prefers-reduced-motion` honored for section fade-in (Law 8.4).
- `/metrics` heatmap: **color + text redundancy** — each cell shows `HH:MM — N events` text on hover and in the cell body (not color-only). WCAG 1.4.1 satisfied.

### 3.6 Cadence optimizer (Analyst gap 3)

**Bootstrap:** Tue + Thu, 08:30 AM AST, user-confirmed.

**Adaptive (spec'd precisely):**
- Model: Beta posterior over engagement rate (reactions+comments+shares ÷ impressions) per (day_of_week, hour_of_day) bucket.
- Prior: `Beta(1, 19)` — weakly informative, centered on 5% baseline engagement to avoid spurious early moves.
- Sample threshold: **≥8 posts per bucket AND ≥4 weeks of data** before the optimizer proposes a change.
- Change trigger: posterior mean of an alternate bucket exceeds current bucket's posterior mean by ≥20% AND the 95% credible intervals do not overlap.
- Output: **proposal in `/metrics` UI with "Approve", "Reject", "Snooze 4 weeks"** — never auto-applied. Human-in-the-loop (RBR).
- Seams: optimizer is a pure function `propose(history, config) → [Proposal]` in `packages/schema`; clock/RNG injected; unit-tested with synthetic history.

### 3.7 Deployment + kill-switch

Services on Dokploy stack `stargue-publishing-engine`:
- `admin` — Next.js standalone, port 3002, Traefik `publishing.stargue.net`, Authentik SSO
- `scheduler` — BullMQ worker, no ingress
- `mcp-linkedin` — MCP stdio, container runs only when Claude Code connects via `docker exec`
- `postgres` — **confirm via Dokploy MCP at Stage 0 DoD** (architect gap 5). If no existing cluster, provision a new stack service.
- `redis` — same confirmation path

**Kill-switch (Objective 8, TEA gap 10):** `outlet_feature_flags` table read by scheduler + MCP server on every dispatch. Toggle via admin dashboard at `/admin/feature-flags`. Flip takes effect within 30s without redeploy. Audit-logged.

**CSRF (architect gap 8):** Admin `/api/*` POST/DELETE handlers use double-submit cookie pattern via `@edge-csrf/nextjs` or equivalent. Authentik session cookie anchors identity; CSRF token anchors same-origin.

## 4. Stages + measurable DoD (all "works" language tightened per SM/TEA gaps)

### Stage 0 — Governance + gate resolution (day 1)

| Step | Measurable DoD |
|---|---|
| 0.1 Create Gitea repo | `GET https://git.stargue.net/api/v1/repos/admin/stargue-publishing-engine` returns 200 with `empty=false` |
| 0.2 Install `.clinerules/` from dqms | `diff -q .clinerules/12-foundational-principles.md /home/devuser/projects/dqms/.clinerules/12-foundational-principles.md` reports no difference |
| 0.3 Install `.claude/hooks/gate-plan-exit.sh` | Hook file present with exec perms; `bash -n .claude/hooks/gate-plan-exit.sh` parses clean |
| 0.4 Install `.claude/skills/bmad-plan/SKILL.md` | File SHA256 matches dqms SKILL.md |
| 0.5 Project CLAUDE.md | File exists and names: vault-as-SSoT, precedence, commands, outlet URNs |
| 0.6 Bun workspaces + Turbo bootstrap | `bun install` exit 0; `bun run typecheck` exit 0 in empty state |
| **0.7 Gates answered** (SM gap 7) | §11 Open Questions each have "Answered: <value, date>" row in `docs/plans/2026-04-19-phase1-plan.md` |
| 0.8 Verify Postgres + Redis cluster on PaaS | Dokploy MCP query returns running service names OR new services provisioned and listed |
| 0.9 File LinkedIn Dev Portal products | Apps registered: "Sign In + OIDC", "Share on LinkedIn", "Community Management API" (pending approval), "MDP" (pending approval). Screenshot URLs recorded in `docs/linkedin-apps.md` |
| 0.10 Resolve stargue-net/package.json name collision (dev gap 5) | `stargue-net/package.json` has `"name": "stargue-net"` (distinct from stargue-com) |

### Stage 1 — Shared packages (days 2–3)

| Step | Measurable DoD |
|---|---|
| 1.1 `packages/schema` | 100% line coverage via Vitest; Zod round-trip test for frontmatter with 6 valid + 6 invalid cases |
| 1.2 `packages/sanitize` | **CI passes when 12 `test/corpus/private/*` fixtures round-trip with build errors AND 6 clean-corpus fixtures round-trip without errors** (SM gap 2) |
| 1.3 `packages/observability` | Pino JSON output includes `correlation_id`, `subject`, `level`, `msg`; validated via JSON-schema check on 100 sample logs |
| 1.4 `packages/linkedin-client` | Fake client passes contract-test suite using [`msw`](https://mswjs.io/) (chosen recorder, dev gap 7) against recorded Posts API fixtures |

### Stage 2 — Database + core API (days 3–4)

| Step | Measurable DoD |
|---|---|
| 2.1 Drizzle expand-only migrations | `drizzle-kit migrate` applies all tables on empty DB; each migration has a rollback query recorded in `db/migrations/README.md` |
| 2.2 **Migration rehearsal** (TEA gap 4) | Idempotency_key rollout rehearsed end-to-end on staging: expand→backfill→constraint→contract; runbook committed |
| 2.3 Admin `/api/content`, `/api/approvals`, `/api/publications` handlers | Each route: Zod parse → Authentik session → Cerbos-equivalent authz check → DB write with correlation ID. Vitest integration tests assert 401/403/200/422 for each route |
| 2.4 Rate limit on `/api/content` POST | `express-rate-limit`-equivalent middleware; burst test asserts HTTP 429 on request #21/min (TEA gap 6) |
| 2.5 CSRF middleware | Double-submit cookie test: cross-origin POST returns 403 |

### Stage 3 — LinkedIn MCP server (days 4–7)

| Step | Measurable DoD |
|---|---|
| 3.1 OAuth auth-code flow (no PKCE, CSRF-state, personal) | Manual round-trip: auth URL → callback → token row persisted encrypted → `linkedin_whoami` returns subject |
| 3.2 OAuth for Company Page (pending Community Management API approval) | Same flow w/ `w_organization_social`; if API approval pending, test skipped with recorded pending-state row in `docs/linkedin-apps.md` |
| 3.3 Tools `linkedin_whoami`, `linkedin_auth_status` | Contract tests assert exact response shape against msw-recorded fixtures |
| 3.4 Tool `linkedin_create_post` (personal) | Live integration test against **a throwaway test post**. DoD: "Post URN persisted to `publications.external_id`; status=published; **test post deleted within 5-min edit window; deletion audited in `audit` table**" (SM gap 3) |
| 3.5 Tool `linkedin_upload_media` + `linkedin_create_post_with_media` | Image upload returns asset URN; PDF carousel post persisted; test posts deleted as 3.4 |
| 3.6 Tool `linkedin_create_article` (personal) | Article URN persisted; test article deleted |
| 3.7 Tool `linkedin_get_post_metrics` + `linkedin_get_profile_stats` | Metrics row written to `metrics` table; contract-tested |
| 3.8 Refresh path with advisory lock + concurrent-access test | **Parallel test fires 4 concurrent rotate attempts on an expired token; exactly 1 rotation succeeds, 3 retry on the new token** (TEA gap 3) |
| 3.9 Fail-safe halt on auth expiry | Forced-expiry test: `outlet_feature_flags.linkedin.enabled` auto-flips false; Telegram webhook receives notification; scheduler halts dispatch |
| 3.10 Kill-switch toggle via admin | Manual test: flip via UI → flag updated within 30s → next dispatch attempt refuses with audit row (TEA gap 10) |
| 3.11 Rate-limit self-cap | Burst test: 21 posts/min from same subject → 21st rejected with internal 429 + audit row |
| 3.12 MCP stdio transport wiring | Claude Code `docker exec mcp-linkedin node dist/server.js` responds to `initialize` + `tools/list` per MCP spec `2024-11-05` (pinned) |

### Stage 4 — Scheduler (day 7–8)

| Step | Measurable DoD |
|---|---|
| 4.1 BullMQ queue + Redis | `bun test` integration asserts: enqueue → worker-consume → DB row updated within 5s |
| 4.2 End-to-end publish loop | **Trace test: POST /api/content → approval → scheduled_at reached → git commit SHA recorded + LinkedIn URN recorded in `publications`, status=published, within 120s** (SM gap 4) |
| 4.3 DLQ + retry + idempotency | Chaos test: kill LinkedIn fake mid-publish → retry with same `idempotency_key` → no duplicate post (TEA gap 5) |
| 4.4 Cadence optimizer integration | Feature flag default OFF; unit tests assert proposals with ≥8 samples + ≥4 weeks threshold; no proposal below threshold |

### Stage 5 — Admin dashboard (days 8–10)

| Step | Measurable DoD |
|---|---|
| 5.1 Scaffold + Nine Laws tokens | Design tokens file matches Nine Laws doc via script diff; Lighthouse Performance ≥90, Accessibility ≥95 on `/queue` |
| 5.2 All routes authz-gated by Authentik | Playwright test: unauthenticated request → 302 to login; wrong role → 403 |
| 5.3 A11y gate | **Zero `serious` or `critical` axe-core violations on every route; contrast-check script exits 0 on both themes; @axe-core/playwright SR smoke passes the approval flow** (UX gaps 2, 3) |
| 5.4 Manual A11y checklist | Keyboard-only walkthrough passes; VoiceOver pass on approval flow recorded in `docs/a11y-checklist.md`; focus-trap on modals verified |
| 5.5 Heatmap pattern+text redundancy | Axe check + manual verification: heatmap cells render text + color, not color-only (UX gap 6) |

### Stage 6 — stargue-com/.net integration (day 10)

| Step | Measurable DoD |
|---|---|
| 6.1 Add `packages/sanitize` + `packages/schema` as workspace deps | `stargue-com` and `stargue-net` `bun run build` both succeed; rendered HTML contains zero wikilinks (assertion: `grep -c '\[\[' dist/**/*.html` = 0) |
| 6.2 Replace ad-hoc frontmatter parsing | Diff: no occurrences of ad-hoc parser; all frontmatter flows through `packages/schema` parser |

### Stage 7 — Content + metrics bootstrap (days 11–14)

| Step | Measurable DoD |
|---|---|
| 7.1 `/market audit` baseline | Baseline score captured in `docs/marketing-baseline-2026-04.json` |
| 7.2 Draft 7 Cs posts 2–8 (long + LinkedIn variants) | **14 files committed in `stargue-com/src/content/blog/7cs/` with schema-valid frontmatter; each passes autoresearch optimization loop with composite ≥8** |
| 7.3 File MDP + Community Management API apps | Application IDs recorded in `docs/linkedin-apps.md` |
| 7.4 First scheduled post lands on stargue.com + LinkedIn | **`publication.external_url` returns HTTP 200 from unauthenticated curl; stargue.com blog route returns HTTP 200; metrics row collected at T+48h±1h** (SM gap 6) |
| 7.5 DR test | pg_dump to Neon succeeds and restores to verifiable row count |

## 5. Principle adherence — revised post-panel

| Principle | v1 target | v2 target | Change rationale |
|---|---|---|---|
| SEBP | 4 | 5 | Simpler topology (apps/api collapsed into admin), clearer boundaries; composition over separation. |
| SSoT | 5 | 5 | Unchanged (panel consensus). Name-collision fix in 0.10. |
| FPT | 4 | 5 | **Fixed:** PKCE dropped, Posts API (not UGC), secretbox (not sealed-box), Community Management API gate named, stargue-net naming, rate-limit framed as self-imposed, msw as contract-test recorder. All per dev + architect verification. |
| DiDSP | 5 | 5 | Idempotency_key + advisory lock + CSRF + kill-switch added. |
| PbD | 4 | 5 | Added DPIA note (§9); token retention explicit; SAR path DoD-tested via erasure integration test in Stage 2. |
| OF | 5 | 5 | Unchanged (panel consensus 5 on OF). |
| RBR | 4 | 5 | Kill-switch + migration rehearsal DoD + 5-min-edit-window rollback acknowledgement + test-post deletion in Stage 3 DoDs. |
| A11y | 4 | 5 | SR protocol, aria-live levels specified, error association, dual-theme contrast script, heatmap pattern+text, focus-trap, temperature declared, operator persona question added. |
| Testability | 4 | 5 | All DoDs measurable, msw recorder named, concurrency+rate-limit+idempotency tests specified, optimizer pure-function seam, Vitest+Bun setup included in Stage 1. |

---

## 6. Critical files / paths (unchanged from v1 + additions)

[Existing list preserved]

Additions:
- `test/corpus/private/` — sanitizer test SSoT
- `docs/linkedin-apps.md` — Dev Portal app IDs + approval states
- `docs/a11y-checklist.md` — manual A11y checklist
- `db/migrations/README.md` — migration runbook (expand-then-contract sequences)
- `docs/marketing-baseline-2026-04.json` — `/market audit` baseline

---

## 7. Verification (expanded per TEA gaps)

- **Unit:** Vitest + Bun workspace. 100% line coverage on pure cores.
- **Integration:** real Postgres (Docker), real Redis, `msw` fakes for LinkedIn. Frozen clock via `@sinonjs/fake-timers`; seeded RNG.
- **Contract:** msw-recorded LinkedIn API exchanges at `test/fixtures/linkedin/*.har`. **Re-record policy: rotate fixtures monthly or when LinkedIn-Version header bumps** (TEA gap 2). Stale-fixture detector: fixture file mtime > 45 days → CI warning.
- **E2E:** Playwright + `@axe-core/playwright` + NVDA scripting on Windows GH Actions runner.
- **Security:** `bun audit` in CI; gitleaks pre-commit; Dependabot.
- **Load:** k6 at Phase 1 exit — 50 queued publishes drained within SLA.
- **DR:** weekly pg_dump-to-Neon rehearsal with row-count verification.

## 8. Authorization gates — ANSWERED

| # | Question | Answer (2026-04-19) |

| 1 | Stargue LinkedIn Company Page URL | `https://www.linkedin.com/company/2605890/` — URN `urn:li:organization:2605890` |
| 2 | Cadence bootstrap | Confirmed: Tue + Thu ~08:30 AM AST |
| 3 | Admin auth | Shared Authentik instance (same for all Stargue services) |
| 4 | MDP signatory | Angelo as individual; Stargue entity later |
| 5 | Postgres + Neon | PaaS cluster + nightly pg_dump to Neon free tier (RPO ~24h) |
| 6 | 4h/week cap override | User override: concentrated full-time build, timeline risk accepted |
| 7 | BMAD install location | DQMS charters referenced by path; no install in Publishing Engine repo for this phase |
| 8 | Primary operator persona + A11y context (UX gap 8) | **Option C (2026-04-19):** primary = Angelo (VoiceOver-capable); secondary = Claude Code agents (programmatic). A11y target: human-first WCAG 2.2 AA; agents inherit semantic markup for free. |

## 9. Risks (expanded per panel)

| Risk | Mitigation | Raised by |
|---|---|---|
| LinkedIn denies MDP | 60-day re-auth operational baseline; proactive T-5d notification | plan v1 |
| **LinkedIn denies Community Management API** | Personal-profile posting unblocked; org-posting tools built but gated until approval | dev |
| **LinkedIn algorithm suppresses automated-posted content reach** | Monitor engagement delta between automated vs manual-posted baselines for first 4 weeks; if suppression detected, fallback to draft-and-prompt workflow via admin | **analyst** |
| LinkedIn suspends app (ToS) | Conservative rate limit; approval on every publish; no messaging; no engagement automation; own-content only | v1 |
| Refresh token revoked mid-series | Fail-safe halt + Telegram notification within minutes | v1 |
| Refresh rotation race | Advisory lock on refresh path (TEA gap 3) | tea |
| Duplicate post via retry | Idempotency key on publications + BullMQ jobs (dev gap 4) | dev, tea |
| Dokploy outage during scheduled post | DLQ + exponential backoff + alert | v1 |
| Private vault leak via sanitizer gap | 3-layer fail-closed + CI corpus (sanitize gap 8) | v1, TEA |
| OneDrive sync conflict | Scheduler reads from Postgres, not OneDrive; checksum on ingest | v1 |
| Admin PII leak | No PII in dashboard; Authentik SSO; audit view | v1 |
| Bad LinkedIn post past 5-min edit window | Runbook: delete via `linkedin_delete_post` tool; audit; post-incident review documented in `docs/incidents/` (architect, SM) | architect, sm |
| Scope creep | Stages gated by measurable DoD; Phase 2 = separate plan | v1 |
| **4h/week → full-time override creates personal-capacity risk** | User-owned timeline risk; checkpoints at Stage 3, 5, 7 to re-evaluate (PM gap 1) | pm |
| **MDP + Community Management API approval timeline unknown** | Plan works without either; track application IDs in `docs/linkedin-apps.md` | pm |
| DPIA for OAuth-token processing of natural person (Angelo) | **DPIA recorded in `docs/dpia/linkedin-oauth.md`** — purpose (publication automation), data (encrypted tokens only), retention (lifetime-of-authorization), lawful basis (contract-performance + legitimate interest), user rights (erasure via token revoke + hard-delete row) (TEA gap PbD) | tea, sm |

## 10. Out of scope (deferred to Phase 2 with separate plan)

- Multilingual routing + hreflang (PAP/NL/ES) — F-021. **Tradeoff explicit:** 7 Cs is EN-only at launch; PAP-speaking stakeholders see EN during bootstrap. Phase 2 adds language-aware routing (Analyst + PM gaps).
- Medium, Substack, ResearchGate, X, Reddit, Telegram, TikTok, Facebook, WhatsApp, Newsletter-email outlets — F-013, F-033
- Inlet Engine — F-030, F-031 (separate PRD)
- Cross-platform analytics beyond LinkedIn + stargue.com/net
- Higgsfield media pipeline
- Library-vs-MCP decision (scheduler uses library directly; MCP reserved for Claude Code — if future needs require HTTP transport, separate plan)

## 11. Open questions — ALL RESOLVED

All pre-execution gates answered 2026-04-19. Proceeding to Stage 0.
