A client cannot name its own tenant. + - **Every** query touching a tenant-owned table (`users`, `flights`, + `bookings`, `passengers`) filters on `tenant_id` as its first parameter. + - A lookup that misses within the tenant returns `ErrNotFound` → **HTTP 404**, + never 403 — so probing for another tenant's record is indistinguishable + from asking for one that does not exist. + - **Do not introduce PostgreSQL row-level security (RLS).** It is a deliberate + choice for this project: per-request session state (`SET LOCAL`) fights + connection pooling and a missed reset leaks across tenants rather than + failing closed. Enforce isolation in the repository layer with the + convention above. If stronger isolation is wanted at scale, prefer + schema- or database-per-tenant, not RLS. + +2. **Security is not optional.** See the security rules below and + `security/VAPT-REPORT.md`. Never weaken a security control to make something + work; flag it instead. + +3. **A change isn't done until its tests pass and prove it.** Assert on + behaviour a user can observe, not on implementation. Never loosen an + assertion to get green. + +4. **Scope discipline.** Do what was asked; don't widen, narrow, or sneak in + unrelated changes. AI-generated PRs that drift in scope are rejected. + +5. **The human is accountable for what merges.** AI generates and reviews; + people own the merge decision on anything security- or tenant-sensitive. + +--- + +## Layout + +``` +backend/ + cmd/api/ server entrypoint, graceful shutdown + internal/ + httpapi/ the route tree (shared by server and tests) + handlers/ HTTP layer — takes tenant id from the identity + middleware/ basic auth + tenant resolution, CORS, recoverer + repository/ ALL SQL; every tenant query filters tenant_id = $1 + auth/ identity carried in request context + config/ .env loading, DSN assembly + database/ pgx pool + models/ API types (camelCase JSON) + testsupport/ per-test tenant harness for the Go suite + migrations/ 001 schema · 002 seed · 003 demo bookings (idempotent) +frontend/ Angular SPA (features/, core/, layout/, shared/) +e2e/ Playwright: pages/ fixtures/ tests/ reporters/ + CLAUDE.md conventions for generating Playwright tests +qa/ scenario cards, the generation prompt, the QA runbook +scripts/ db.mjs, report + hook helpers +app.ps1 start/stop/restart/rebuild/status/logs the app +run-tests.ps1 run any test layer, log, emit JUnit + evidence +``` + +--- + +## Running, testing, data + +Everything has an npm script or a ps1; prefer them over ad-hoc commands. + +```powershell +.\app.ps1 start # DB up, API (:8080) + Angular (:4200) +.\app.ps1 rebuild -Clean # build Go binary + Angular bundle +.\run-tests.ps1 -Layer all # backend + web + ui, logged, JUnit + evidence +.\run-tests.ps1 -Layer unit # fast: backend + web, no browser +npm run db:migrate | db:reset # schema + seed (reset re-seeds fresh) +npm run report # open the evidence report +``` + +- **Test output** lands in `.testlogs//` (logs, `summary.json`, + `junit.xml`) and `e2e/evidence-report/` (screenshots + API request/response). + All are git-ignored run artifacts. +- **Demo data is time-relative** — seeded flights depart within 21 days of seed + time and go stale after ~3 weeks. `run-tests.ps1` re-seeds automatically via + `npm run db:check`; if the UI shows no flights, run `npm run db:reset`. + +--- + +## Conventions + +**Go.** `gofmt` + `go vet` clean.

The owner of all tenant-scoped data.

Enforced in the application layer. | +| **PNR / Booking reference** | The 6-character code identifying a booking (e.g. `QX7A2M`). Unique within a tenant. | +| **Flight (inventory)** | A sellable route on a date at a fare with a seat count, owned by one tenant. The same physical route is a separate row per tenant. | +| **Cabin class** | `economy`, `premium_economy`, `business`, or `first`. | +| **Seats available / total** | Remaining and original seats on a flight. Bookings decrement available; cancellations restore it. | +| **Oversell** | Selling more seats than exist. Prevented by a row-locked transaction at booking time. | +| **IATA code** | Standard airport (3-letter, e.g. `JFK`) or airline (2-letter, e.g. `AA`) code. | +| **Reference data** | Global, non-tenant data: airports and airlines, shared by all tenants. | +| **X-Tenant** | The HTTP header naming which agency a request is for (or taken from the subdomain). | +| **Basic auth** | The authentication scheme: `Authorization: Basic base64(email:password)`, verified within the named tenant. | +| **Suspended tenant** | An agency whose users cannot sign in and which is hidden from the agency picker. | +| **Evidence report** | The e2e test report showing screenshots and the API request/response for each scenario (`e2e/evidence-report/`). | +| **Scenario card** | A structured definition of one test scenario in `qa/scenarios/`; the source a Playwright test is generated from. | +| **Binding (test layer)** | A test of the seam between layers — that the UI sends what the API expects and renders what it returns. | diff --git a/docs/wiki/README.md b/docs/wiki/README.md new file mode 100644 index 0000000..de9d9de --- /dev/null +++ b/docs/wiki/README.md @@ -0,0 +1,24 @@ +# TravelHub product wiki + +The product reference for TravelHub — what it is, how it is modelled, and how it +behaves.
