feat(supply-chain): Global Shipping Intelligence — Sprint 0 + Sprint 1 (#2870)

* feat(supply-chain): Sprint 0 — chokepoint registry, HS2 sectors, war_risk_tier - src/config/chokepoint-registry.ts: single source of truth for all 13 canonical chokepoints with displayName, relayName, portwatchName, corridorRiskName, baselineId, shockModelSupported, routeIds, lat/lon - src/config/hs2-sectors.ts: static dictionary for all 99 HS2 chapters with category, shockModelSupported (true only for HS27), cargoType - server/worldmonitor/supply-chain/v1/_chokepoint-ids.ts: migrated to derive CANONICAL_CHOKEPOINTS from chokepoint-registry; no data duplication - src/config/geo.ts + src/types/index.ts: added chokepointId field to StrategicWaterway interface and all 13 STRATEGIC_WATERWAYS entries - src/components/MapPopup.ts: switched chokepoint matching from fragile name.toLowerCase() to direct chokepointId === id comparison - server/worldmonitor/intelligence/v1/_shock-compute.ts: migrated from old IDs (hormuz/malacca/babelm) to canonical IDs (hormuz_strait/malacca_strait/ bab_el_mandeb); same for CHOKEPOINT_LNG_EXPOSURE - proto/worldmonitor/supply_chain/v1/supply_chain_data.proto: added WarRiskTier enum + war_risk_tier field (field 16) on ChokepointInfo - get-chokepoint-status.ts: populates warRiskTier from ChokepointConfig.threatLevel via new threatLevelToWarRiskTier() helper (FREE field, no PRO gate) * feat(supply-chain): Sprint 1 — country chokepoint exposure index + sector ring S1.1: scripts/shared/country-port-clusters.json ~130 country → {nearestRouteIds, coastSide} mappings derived from trade route waypoints; covers all 6 seeded Comtrade reporters plus major trading nations. S1.2: scripts/seed-hs2-chokepoint-exposure.mjs Daily cron seeder. Pure computation — reads country-port-clusters.json, scores each country against CHOKEPOINT_REGISTRY route overlap, writes supply-chain:exposure:{iso2}:{hs2}:v1 keys + seed-meta (24h TTL). S1.3: RPC get-country-chokepoint-index (PRO-gated, request-varying) - proto: GetCountryChokepointIndexRequest/Response + ChokepointExposureEntry - handler: isCallerPremium gate; cachedFetchJson 24h; on-demand for any iso2 - cache-keys.ts: CHOKEPOINT_EXPOSURE_KEY(iso2, hs2) constant - health.js: chokepointExposure SEED_META entry (48h threshold) - gateway.ts: slow-browser cache tier - service client: fetchCountryChokepointIndex() exported S1.4: Chokepoint popup HS2 sector ring chart (PRO-gated) Static trade-sector breakdown (IEA/UNCTAD estimates) per 9 major chokepoints. SVG donut ring + legend shown for PRO users; blurred lockout + gate-hit analytics for free users. Wired into renderWaterwayPopup(). 🤖 Generated with Claude Sonnet 4.6 via Claude Code (https://claude.com/claude-code) + Compound Engineering v2.49.0 Co-Authored-By: Claude Sonnet 4.6 (200K context) <noreply@anthropic.com> * fix(tests): update energy-shock-v2 tests to use canonical chokepoint IDs CHOKEPOINT_EXPOSURE and CHOKEPOINT_LNG_EXPOSURE keys were migrated from short IDs (hormuz, malacca, babelm) to canonical registry IDs (hormuz_strait, malacca_strait, bab_el_mandeb) in Sprint 0. Test fixtures were not updated at the time; fix them now. * fix(tests): update energy-shock-seed chokepoint ID to canonical form VALID_CHOKEPOINTS changed to canonical IDs in Sprint 0; the seed test that checks valid IDs was not updated alongside it. * fix(cache-keys): reword JSDoc comment to avoid confusing bootstrap test regex The comment "NOT in BOOTSTRAP_CACHE_KEYS" caused the bootstrap.test.mjs regex to match the comment rather than the actual export declaration, resulting in 0 entries found. Rephrase to "excluded from bootstrap". * fix(supply-chain): address P1 review findings for chokepoint exposure index - Add get-country-chokepoint-index to PREMIUM_RPC_PATHS (CDN bypass) - Validate iso2/hs2 params before Redis key construction (cache injection) - Fix seeder TTL to 172800s (2× interval) and extend TTL on skipped lock - Fix CHOKEPOINT_EXPOSURE_SEED_META_KEY to match seeder write key - Render placeholder sectors behind blur gate (DOM data leakage) - Document get-country-chokepoint-index in widget agent system prompts * fix(lint): resolve Biome CI failures - Add biome.json overrides to silence noVar in HTML inline scripts, disable linting for public/ vendor/build artifacts and pro-test/ - Remove duplicate NG and MW keys from country-port-clusters.json - Use import attributes (with) instead of deprecated assert syntax * fix(build): drop JSON import attribute — esbuild rejects `with` syntax --------- Co-authored-by: Claude Sonnet 4.6 (200K context) <noreply@anthropic.com>

+# get-country-chokepoint-index missing from PREMIUM_RPC_PATHS — CDN serves PRO data to free users
+
+## Problem Statement
+`get-country-chokepoint-index` is absent from `PREMIUM_RPC_PATHS` in `server/shared/premium-paths.ts`. The `isPremium` flag is therefore `false`, causing `CDN-Cache-Control: public, s-maxage=900` to be set. A PRO user's full exposures response can be cached by Vercel CDN and served to a free user who hits the same iso2+hs2 pair before the edge cache expires.
+
+## Findings
+`server/gateway.ts` — `isPremium` check references `PREMIUM_RPC_PATHS`; path `/api/supply-chain/v1/get-country-chokepoint-index` is absent from that set.
+
+## Proposed Solutions
+
+### Option A: Add path to PREMIUM_RPC_PATHS (Recommended)
+- Add `'/api/supply-chain/v1/get-country-chokepoint-index'` to `PREMIUM_RPC_PATHS` in `server/shared/premium-paths.ts` (1 line)
+- Sets `isPremium=true` → `cdnCache=null` → no CDN caching of PRO responses
+- Effort: Small | Risk: Low
+
+### Option B: Add per-handler CDN override
+- In the handler itself, explicitly set `CDN-Cache-Control: no-store` regardless of `isPremium`
+- Effort: Small | Risk: Low (but diverges from the shared pattern)
+
+## Acceptance Criteria
+- [ ] `PREMIUM_RPC_PATHS` includes `/api/supply-chain/v1/get-country-chokepoint-index`
+- [ ] After fix, `CDN-Cache-Control` header is absent or `no-store` on this endpoint
+- [ ] PRO response for iso2+hs2 pair is never cached at the Vercel edge

+# Unvalidated iso2 and hs2 params used as Redis cache key segments — cache pollution risk
+
+## Problem Statement
+`server/worldmonitor/supply-chain/v1/get-country-chokepoint-index.ts` uses `req.iso2` and `req.hs2` directly as segments of the Redis cache key with no format validation. An attacker can pass arbitrary strings (e.g. `US/../something`, `*`, or very long strings), generating unbounded distinct cache entries and polluting Redis. The seeder already validates `k.length === 2` before writing; the handler must apply the same constraint.
+
+## Findings
+`get-country-chokepoint-index.ts:68-69` — `CHOKEPOINT_EXPOSURE_KEY(req.iso2, hs2)` called with no prior validation of `req.iso2` or `hs2` format.
+
+## Proposed Solutions
+
+### Option A: Add format guards before cache key construction (Recommended)
+- Add `if (!/^[A-Z]{2}$/.test(req.iso2)) return emptyResponse(req.iso2, hs2);` before cache key construction
+- Add `if (!/^\d{1,4}$/.test(hs2)) hs2 = '27';` to fall back to the default HS2 chapter
+- Mirrors the `k.length === 2` guard already present in the seeder
+- Effort: Small | Risk: Low
+
+### Option B: Sanitize at the RPC request schema level
+- Add a Zod/joi schema to the handler's request validation layer that enforces ISO2 and numeric HS2 formats upstream
+- Effort: Medium | Risk: Low
+
+## Acceptance Criteria
+- [ ] Handler rejects (returns empty response) for non-uppercase-2-letter `iso2` values
+- [ ] Handler rejects or coerces invalid `hs2` values
+- [ ] No garbage/arbitrary keys appear in Redis under the exposure namespace
+- [ ] Existing valid requests (e.g. `iso2=US&hs2=27`) continue to work correctly

+# Seeder lock.skipped early return doesn't call extendExistingTtl — health shows STALE_SEED during Redis transient failure
+
+## Problem Statement
+`scripts/seed-hs2-chokepoint-exposure.mjs:123` — `if (lock.skipped) return` exits immediately without extending existing exposure key TTLs. Per the seeder gold standard (documented in project memory `feedback_seed_meta_skipped_path.md`), the skipped path must call `extendExistingTtl` on the existing keys before returning, so that health checks continue to see valid-if-stale data rather than reporting STALE_SEED.
+
+## Findings
+Line 123 in `scripts/seed-hs2-chokepoint-exposure.mjs` — bare `return` after `lock.skipped` check. The seed-meta key is never written in this path, so health checks that observe a missed cron window will incorrectly classify the seeder as STALE_SEED rather than degraded-but-alive.
+
+## Proposed Solutions
+
+### Option A: Mirror seed-energy-spine.mjs skipped path pattern (Recommended)
+- After `lock.skipped` is true, call `extendExistingTtl` on all existing exposure keys
+- Write seed-meta with `count=0` and `status='skipped'` before returning
+- Matches the pattern from `seed-energy-spine.mjs`
+- Effort: Small | Risk: Low
+
+### Option B: Write seed-meta only (no TTL extension)
+- Write seed-meta with `count=0, status='skipped'` without extending TTLs
+- Prevents STALE_SEED in health but keys can still expire if multiple cron cycles are skipped
+- Effort: Small | Risk: Medium
+
+## Acceptance Criteria
+- [ ] Under simulated Redis lock contention, health endpoint shows `degraded` (not `STALE_SEED`) status
+- [ ] Existing exposure keys retain their TTL after a skipped cron run
+- [ ] seed-meta is written with `count=0` in the skipped path

+# Seeder data TTL is 1x cron interval — keys expire at the next cron boundary with no buffer
+
+## Problem Statement
+`scripts/seed-hs2-chokepoint-exposure.mjs:27` — `TTL_SECONDS = 86400` (24h). The cron runs daily (24h interval). TTL = 1x interval means keys expire exactly when the next cron run is due. Any single missed or delayed cron run causes all 130 country exposure keys to expire before fresh data is written. The seeder gold standard requires TTL >= 2x the cron interval to survive one missed cycle.
+
+## Findings
+`TTL_SECONDS = 86400` (line 27) with a daily cron schedule. `seed-energy-spine.mjs` uses `SPINE_TTL_SECONDS = 172800` (48h) as the correct reference implementation.
+
+## Proposed Solutions
+
+### Option A: Change TTL_SECONDS to 172800 (Recommended)
+- Set `TTL_SECONDS = 172800` (48h = 2x the 24h cron interval)
+- Matches the pattern from `seed-energy-spine.mjs`
+- One cron miss no longer causes all 130 country exposure keys to expire
+- Effort: Small | Risk: Low
+
+### Option B: Change TTL_SECONDS to 129600 (1.5x interval)
+- Set `TTL_SECONDS = 129600` (36h = 1.5x interval)
+- Provides some buffer but does not fully survive a missed cron cycle
+- Effort: Small | Risk: Medium
+
+## Acceptance Criteria
+- [ ] `TTL_SECONDS >= 172800` in `seed-hs2-chokepoint-exposure.mjs`
+- [ ] `health.js` `maxStaleMin` value remains valid (must be <= TTL in minutes)
+- [ ] After one simulated missed cron run, exposure keys are still present in Redis with positive TTL

+# CHOKEPOINT_EXPOSURE_SEED_META_KEY constant has wrong value — future consumers will read an empty key
+
+## Problem Statement
+`server/_shared/cache-keys.ts:72` exports `CHOKEPOINT_EXPOSURE_SEED_META_KEY = 'supply-chain:exposure:seed-meta:v1'`. The seeder writes to `'seed-meta:supply_chain:chokepoint-exposure'` (different namespace, hyphens vs underscores). The constant is orphaned (zero usage in codebase). If any future code imports it to check seeder health, it will silently read a nonexistent Redis key and conclude the seeder is in an unknown state.
+
+## Findings
+`cache-keys.ts:72` — exported constant value does not match the key the seeder actually writes. Seeder `META_KEY` on line 20 of `seed-hs2-chokepoint-exposure.mjs` has the real value `'seed-meta:supply_chain:chokepoint-exposure'`. Current grep confirms zero consumers of `CHOKEPOINT_EXPOSURE_SEED_META_KEY`.
+
+## Proposed Solutions
+
+### Option A: Delete the orphaned constant (Recommended)
+- Remove `CHOKEPOINT_EXPOSURE_SEED_META_KEY` from `server/_shared/cache-keys.ts` (it has no consumers)
+- Use `META_KEY` inside the seeder directly; `health.js` already references the correct string literal
+- Eliminates the silent wrong-key trap before any consumer is added
+- Effort: Small | Risk: Low
+
+### Option B: Correct the constant value and add a comment
+- Change the value to `'seed-meta:supply_chain:chokepoint-exposure'` to match the seeder
+- Add a comment noting it is reserved for future health check use
+- Effort: Small | Risk: Low (but leaves an unused export)
+
+## Acceptance Criteria
+- [ ] No orphaned constant with wrong value exists in `cache-keys.ts`
+- [ ] `grep` confirms the key string used in `health.js` matches what the seeder writes
+- [ ] TypeScript compilation passes after removal

+# Blurred sector ring passes real sector data through renderSectorRing — DOM readable despite CSS blur
+
+## Problem Statement
+`src/components/MapPopup.ts` — when `!isPro`, the locked-state render path calls `renderSectorRing(sectors)` with real `CHOKEPOINT_HS2_SECTORS` data (actual share percentages and labels). The SVG is then blurred via `filter:blur(4px)`. CSS blur is a visual effect only; the SVG `stroke` colors derived from real data, the legend text (`Energy 78%`, `Chemicals 9%`, etc.), and all percentage values are fully readable in the DOM via DevTools. A free user can inspect the sector breakdown by reading the HTML source.
+
+## Findings
+`MapPopup.ts` lines 1215-1220 — `renderSectorRing(sectors)` called with full real data for the blurred lockout div. The actual sector shares and labels (e.g. `Energy 78%`) are present verbatim in the rendered SVG DOM, accessible to any user who opens browser DevTools.
+
+## Proposed Solutions
+
+### Option A: Replace real data with placeholder data in non-pro path (Recommended)
+- For the non-pro path, pass zeroed/placeholder data to `renderSectorRing` (e.g. all shares = 20, all labels = '?')
+- The blur overlay still conveys the existence of a chart without leaking the actual distribution
+- Effort: Small | Risk: Low
+
+### Option B: Omit renderSectorRing entirely in non-pro path
+- Render only the lock icon overlay without calling `renderSectorRing` at all
+- Simpler but loses the visual affordance that a chart exists behind the paywall
+- Effort: Small | Risk: Low
+
+## Acceptance Criteria
+- [ ] DOM inspection of the non-pro waterway popup shows no real sector share percentages
+- [ ] DOM inspection shows no real sector label names (e.g. "Energy", "Chemicals") with real values
+- [ ] Pro users continue to see the full real sector ring with correct data
+- [ ] Visual blur effect is preserved for non-pro users

+# get-country-chokepoint-index not in widget system prompt — agents cannot discover or call this endpoint
+
+## Problem Statement
+`scripts/ais-relay.cjs` widget system prompt lists known supply-chain RPCs (line ~9667) but `get-country-chokepoint-index` is absent. Agents asked "what is Country X's chokepoint exposure?" have no path to this data. The RPC is HTTP-callable but invisible to the agent layer.
+
+## Findings
+`scripts/ais-relay.cjs:9667` — supply-chain RPC list omits the new endpoint. `src/config/commands.ts` has no CMD+K entry for the exposure index. Without system prompt inclusion, widget agents cannot discover, reason about, or invoke this RPC, making the feature inaccessible via the AI interface despite being live.
+
+## Proposed Solutions
+
+### Option A: Add RPC to system prompt and CMD+K (Recommended)
+- Add `get-country-chokepoint-index?iso2=XX[&hs2=27] (PRO only — returns empty if not authenticated)` to the supply-chain RPC block in the widget system prompt in `scripts/ais-relay.cjs`
+- Add a CMD+K command entry in `src/config/commands.ts` for the chokepoint exposure index
+- Effort: Small | Risk: Low
+
+### Option B: Add to system prompt only
+- Add the RPC description to the agent system prompt without adding a CMD+K entry
+- Agents gain discoverability but keyboard-driven users cannot surface the feature
+- Effort: Small | Risk: Low
+
+## Acceptance Criteria
+- [ ] Widget agent asked about a country's chokepoint exposure can identify and call `get-country-chokepoint-index`
+- [ ] CMD+K search includes an entry for the chokepoint exposure index
+- [ ] System prompt entry correctly documents the PRO-only restriction and the `hs2` default parameter
