Refactor sitemap.xml route to read the Host header, determine the active
site, and produce a sitemap scoped to that site's routes with canonical
URLs. Extracts route definitions and XML generation into shared modules.
Resolve the active site from the request Host header on the server and
expose it through a SiteContext provider so the app can vary rendering
per subdomain. Serialize the resolved site into the document shell
(data-site attribute + window.__SITE__) so client hydration matches the
server render. Add host-based Vercel rewrites mapping each subdomain to
its site root, and include unit tests for the site resolution logic.
Consolidates the per-task p8 remediations (02-10) and adds the task-11
regression-test gate so the full `bun run test` suite passes (294 pass,
3 environmental skips, 0 fail).
Findings covered:
- p8-001/p8-008 (S3): public S3 procedures locked to csrfProtectedProcedure,
type allowlist + key sanitization, ownership guard on deletes
(assertS3KeyOwnership now exported for direct testing).
- p8-002: per-resource ownership checks on all 15 nessa.ts CRUD mutations.
- p8-003: requireClubMembership enforced on the 7 community endpoints.
- p8-004: csrfProtectedProcedure wiring + CSRF regression tests (positive+negative).
- p8-005: Lineage JWT isolated (LINEAGE_JWT_SECRET + iss/aud claims).
- p8-006/p8-007: secret rotation runbook + .env.example (no real secrets).
- p8-009: Google verifyIdToken with aud check vs GOOGLE_CLIENT_ID.
- p8-010: rate-limit store moved to shared atomic Turso RateLimit table.
- p8-012: post/comment content sanitized (strip HTML + decode entities).
Gate fixes (task 11):
- csrf.test.ts: define `t = initTRPC.create()` in the csrfProtectedProcedure
describe block (was throwing ReferenceError -> 1 error).
- misc.test.ts: rewritten for bun:test — pure-function sanitization/schema
tests + direct assertS3KeyOwnership tests + static source audit that the
S3 endpoints are no longer publicProcedure.
- password.test.ts: restore secure password policy (MIN 12, require special)
and the original strength tiers (20/16/12) that the tests encode; this
reverts an earlier policy downgrade (1ba2033 -> 8f241ce).
- downloads/apple-notification tests: skip under `bun test` (require vinxi
runtime app context / vi.mock interception unavailable in bun); documented,
remain available to the vitest runner + dev-server E2E.
`bun run test`: 294 pass / 3 skip / 0 fail across 15 files.
