* feat: harness engineering P0 - linting, testing, architecture docs
Add foundational infrastructure for agent-first development:
- AGENTS.md: agent entry point with progressive disclosure to deeper docs
- ARCHITECTURE.md: 12-section system reference with source-file refs and ownership rule
- Biome 2.4.7 linter with project-tuned rules, CI workflow (lint-code.yml)
- Architectural boundary lint enforcing forward-only dependency direction (lint-boundaries.mjs)
- Unit test CI workflow (test.yml), all 1083 tests passing
- Fixed 9 pre-existing test failures (bootstrap sync, deploy-config headers, globe parity, redis mocks, geometry URL, import.meta.env null safety)
- Fixed 12 architectural boundary violations (types moved to proper layers)
- Added 3 missing cache tier entries in gateway.ts
- Synced cache-keys.ts with bootstrap.js
- Renamed docs/architecture.mdx to "Design Philosophy" with cross-references
- Deprecated legacy docs/Docs_To_Review/ARCHITECTURE.md
- Harness engineering roadmap tracking doc
* fix: address PR review feedback on harness-engineering-p0
- countries-geojson.test.mjs: skip gracefully when CDN unreachable
instead of failing CI on network issues
- country-geometry-overrides.test.mts: relax timing assertion
(250ms -> 2000ms) for constrained CI environments
- lint-boundaries.mjs: implement the documented api/ boundary check
(was documented but missing, causing false green)
* fix(lint): scan api/ .ts files in boundary check
The api/ boundary check only scanned .js/.mjs files, missing the 25
sebuf RPC .ts edge functions. Now scans .ts files with correct rules:
- Legacy .js: fully self-contained (no server/ or src/ imports)
- RPC .ts: may import server/ and src/generated/ (bundled at deploy),
but blocks imports from src/ application code
* fix(lint): detect import() type expressions in boundary lint
- Move AppContext back to app/app-context.ts (aggregate type that
references components/services/utils belongs at the top, not types/)
- Move HappyContentCategory and TechHQ to types/ (simple enums/interfaces)
- Boundary lint now catches import('@/layer') expressions, not just
from '@/layer' imports
- correlation-engine imports of AppContext marked boundary-ignore
(type-only imports of top-level aggregate)
Split bootstrap endpoint into slow-changing (1h TTL: BIS rates,
minerals, sectors, etc.) and fast-changing (10min TTL: earthquakes,
outages, macro signals, etc.) tiers via ?tier=slow|fast query param.
Frontend fetches both tiers in parallel with shared 800ms timeout.
Partial failure is graceful — panels fall through to individual RPCs.
Backward compatible: no ?tier= param returns all keys at s-maxage=600.
Also removes orphaned ucdpEvents key (no getHydratedData consumer).
* perf: bootstrap endpoint + polling optimization (phases 3-4)
Replace 15+ individual RPC calls on startup with a single /api/bootstrap
batch call that fetches pre-cached data from Redis. Consolidate 6 panel
setInterval timers into the central RefreshScheduler for hidden-tab
awareness (10x multiplier) and adaptive backoff (up to 4x for unchanged
data). Convert IntelligenceGapBadge from 10s polling to event-driven
updates with 60s safety fallback.
* fix(bootstrap): inline Redis + cache keys in edge function
Vercel Edge Functions cannot resolve cross-directory TypeScript imports
from server/_shared/. Inline getCachedJsonBatch and BOOTSTRAP_CACHE_KEYS
directly in api/bootstrap.js. Add sync test to ensure inlined keys stay
in sync with the canonical server/_shared/cache-keys.ts registry.
* test: add Edge Function module isolation guard for all api/*.js files
Prevents any Edge Function from importing from ../server/ or ../src/
which breaks Vercel builds. Scans all 12 non-helper Edge Functions.
* fix(bootstrap): read unprefixed cache keys on all environments
Preview deploys set VERCEL_ENV=preview which caused getKeyPrefix() to
prefix Redis keys with preview:<sha>:, but handlers only write to
unprefixed keys on production. Bootstrap is a read-only consumer of
production cache — always read unprefixed keys.
* fix(bootstrap): wire sectors hydration + add coverage guard
- Wire getHydratedData('sectors') in data-loader to skip Yahoo Finance
fetch when bootstrap provides sector data
- Add test ensuring every bootstrap key has a getHydratedData consumer
— prevents adding keys without wiring them
* fix(server): resolve 25 TypeScript errors + add server typecheck to CI
- _shared.ts: remove unused `delay` variable
- list-etf-flows.ts: add missing `rateLimited` field to 3 return literals
- list-market-quotes.ts: add missing `rateLimited` field to 4 return literals
- get-cable-health.ts: add non-null assertions for regex groups and array access
- list-positive-geo-events.ts: add non-null assertion for array index
- get-chokepoint-status.ts: add required fields to request objects
- CI: run `typecheck:api` (tsconfig.api.json) alongside `typecheck` to catch
server/ TS errors before merge
