It currently + cannot, so those assignments fail. +- **`serverSupplies`** now checks the caller's role. Previously a talent-only + derived column was treated as server-supplied for every role, so an + **operator** creating a job application without an email passed validation and + hit a NOT NULL violation — **a 500 where the contract promises 422.** + +## 4. The required extra commit — cookie posture + +`b6f8655` alone derives `SameSite` from whether a CORS allowlist is configured: +non-empty ⇒ `None`. On this host the allowlist *is* non-empty, so deploying it +as-is flips the session cookie from `Lax` to `None`. + +**`SameSite` is the only CSRF protection this API has.** There is no CSRF token. + +The derivation is wrong for this topology, because CORS and SameSite answer +different questions: + +- **CORS** is about **origin**. `platform.krowforce.com` → `mcp.krowforce.com` + is cross-origin, so the allowlist is genuinely required. Confirmed live: that + origin returns `204` with the origin echoed; an unlisted origin returns `403`. +- **SameSite** is about **site**. Both share the registrable domain + `krowforce.com`, so they are **same-site** and a `Lax` cookie is already sent + on those requests. + +So the correct configuration is *CORS on, `SameSite=Lax`* — a combination +`b6f8655` cannot express. + +The commit makes an explicit `HTTP_COOKIE_SAMESITE` authoritative and leaves the +CORS-derived value as the default when it is unset. It also closes a trap: +`config.Load` has always parsed and validated that variable, and nothing read +it, so a deployment that set it saw it silently ignored. + +``` +internal/config/config.go unset is "" rather than defaulting to "lax" +internal/httpserver/auth.go explicit value wins; allowlist decides the default +internal/httpserver/samesite_test.go the full matrix, pinned +``` + +`docker-compose.yml` already passes `HTTP_COOKIE_SAMESITE: ${…:-lax}`, so a +compose deploy keeps `Lax` without any `.env` change. + +> **Do not empty `HTTP_CORS_ORIGINS`.** It looks like a way to keep `Lax` +> without a code change, and it would take `platform.krowforce.com` offline — +> that frontend calls the API cross-origin from the browser. + +## 5. Rollout + +Migrations first, then the binary — the order `docker-compose.yml` already +encodes through `depends_on: service_completed_successfully`. There is nothing +to migrate this time, but the step is a no-op rather than something to skip. + +```sh +# On the host, from the repository root +git fetch origin && git checkout b6f8655 # or the extra commit from §4 +cd infrastructure +docker compose build api +docker compose up -d --no-deps migrate # exits 0, nothing to apply +docker compose up -d --no-deps api +docker compose ps # api healthy +docker compose logs -n 50 api # expect: "endpoints":53 +``` + +`"endpoints":53` in the startup log is the single fastest confirmation that the +right binary is running. + +## 6. Verification + +```sh +KROW_EMAIL=… KROW_PASSWORD=… ./scripts/verify-deployment.sh +``` + +Read-only by default. Add `--write` to prove the write path reaches PostgreSQL; +it creates one posting with `status: draft`, which is invisible to talent — and +permanent, because `JobPosting` has no `DELETE`. + +It checks, in order: `/health` and whether the schema reads `degraded`; login +and the issued cookie; the caller's `role` (a `talent` role explains almost every +403); `GET /owliver/suggestions` as the version discriminator; that +`/api/v1/positions` still `404`s; `GET /job-postings`; both suggestion modes and +the 3-item cap; and the `SameSite` attribute actually being served. + +Exit status is the number of failures, so it can gate a rollout. + +### The resource is `job-postings` + +`/api/v1/positions` has never existed in this API. Every `/positions` in the +frontend is a React Router **UI** route. Two tests assert the phantom stays +absent — `TestThereIsNoPositionsResource` and the script's own check — so nobody +"fixes" a future 404 by adding a duplicate resource. + +## 7. Rollback + +The previous image is still on the host. + +```sh +docker compose down api +git checkout cadea4b +docker compose build api && docker compose up -d --no-deps api +``` + +No schema change means rollback is clean: nothing to reverse, and the old binary +runs against the current schema unchanged. + +## 8. Separately — the deployed frontends are not reaching the API + +Found while verifying, out of scope for this deploy, and more severe than the 404. + +`platform.krowforce.com` is built with +`VITE_API_BASE_URL=https://mcp.krowforce.com/api/v1` — an absolute cross-origin +URL. The repository's own `.env` warns against this at length, and +`httpClient.js` has a guard for it that is compiled out of production builds, so +it fails silently. + +`app.krowforce.com` is worse off: its origin is **not** on the backend's +allowlist (`403` at preflight), and its bundle carries neither `auth/login` nor +any reference to the API host. + +Both hosts also serve their SPA for `/api/v1/*` — `GET /api/v1/me` on either +returns `index.html` with status `200`. The shipped `nginx.conf` has no `/api` +proxy at all, and `try_files $uri $uri/ /index.html` swallows every API path. + +The fix is a `/api` and `/health` `proxy_pass` in the frontend's nginx plus a +rebuild with `VITE_API_BASE_URL=/api/v1`, which is what the same-origin design +assumes. That is a frontend deployment change and belongs in its own rollout. diff --git a/evals/activity-agent.json b/evals/activity-agent.json new file mode 100644 index 0000000..8e27a1d --- /dev/null +++
