feat(regulatory): classify and publish regulatory actions

[lspassos1]

Summary

This adds the second regulatory RSS step by classifying normalized actions into high / medium / low, computing aggregate counts, and publishing the final payload to regulatory:actions:v1 via runSeed.

Root cause

The fetch/parse seeder from #2564 produces stable normalized actions, but the pipeline still needed tiering logic and Redis publication before cross-source signals could consume regulatory events.

Changes

• add the HIGH_KEYWORDS and MEDIUM_KEYWORDS classification rules from feat(regulatory): seed-regulatory-actions.mjs — classify + Redis write #2493
• classify each action with tier and matchedKeywords, using word-boundary matching to avoid false positives like ban inside bank
• build the final seed payload with actions, fetchedAt, recordCount, highCount, and mediumCount
• wire main() through runSeed('regulatory', 'actions', 'regulatory:actions:v1', ...) with TTL 7200 and an empty-array-safe validateFn
• expand tests/regulatory-seed-unit.test.mjs to cover classification, payload counts, fetch-to-payload flow, and the runSeed wiring

Validation

• node --test tests/regulatory-seed-unit.test.mjs
• node -e "import('./scripts/seed-regulatory-actions.mjs').then(async (m) => { const data = await m.fetchRegulatoryActionPayload(); process.stdout.write(JSON.stringify({recordCount: data.recordCount, highCount: data.highCount, mediumCount: data.mediumCount, first: data.actions[0]}, null, 2) + '\\n'); })"
• node -e "import('./scripts/seed-regulatory-actions.mjs').then(() => process.stdout.write('import-ok\\n'))"

Risk

Low risk. This only evolves the new regulatory seeder introduced in #2564 and adds focused test coverage around the new classification/publish behavior.

Note

This branch is currently stacked on #2564. Until #2564 merges, this PR includes the parent fetch/parse commit in the diff.

Greptile Summary

This PR completes the second step of the regulatory RSS pipeline by adding keyword-based tiering (high/medium/low) to normalized regulatory actions and publishing the resulting payload to regulatory:actions:v1 via runSeed with a 2-hour TTL. Classification uses word-boundary regex matching to avoid false positives (e.g. ban inside bank), and the final payload includes highCount/mediumCount aggregate fields for downstream consumers. The implementation is well-structured and the test coverage is thorough.

Key findings:

• Missing bootstrap hydration (api/bootstrap.js) — AGENTS.md requires all new data sources to be wired for bootstrap hydration; regulatory:actions:v1 is absent from api/bootstrap.js, meaning first page loads will not receive regulatory data until a cache-miss fetch cycle completes.
• fetch convention violation — All four functions that accept a fetchImpl parameter default to globalThis.fetch directly (fetchImpl = globalThis.fetch). AGENTS.md explicitly requires the (...args) => globalThis.fetch(...args) arrow-wrapper pattern instead. This is consistent with how other seed scripts in the repo invoke fetch inline via globalThis.fetch(url, opts).
• FINRA feed over plain HTTP — All other feed URLs use HTTPS; the FINRA entry uses http://feeds.finra.org/FINRANotices.
• Regex pre-compilation — findMatchedKeywords compiles a new RegExp for each keyword on every classifyAction call; since the keyword lists are constant, pre-compiling at module load would be a minor efficiency improvement.

Confidence Score: 4/5

• Safe to merge after wiring bootstrap hydration in api/bootstrap.js; all other findings are style/convention issues.
• One P1 finding: regulatory:actions:v1 is not wired in api/bootstrap.js, which AGENTS.md marks as a MUST for new data sources. Without it, the key is invisible to first-load hydration. The remaining findings (fetch convention, HTTP URL, regex pre-compilation) are all P2 style/best-practice items that do not affect runtime correctness in the Node.js Railway environment where these scripts execute.
• scripts/seed-regulatory-actions.mjs — bootstrap wiring and fetch convention; api/bootstrap.js — needs regulatory:actions:v1 entry added.

Important Files Changed

Filename	Overview
scripts/seed-regulatory-actions.mjs	New regulatory seed script: fetches 5 agency RSS/Atom feeds, classifies actions as high/medium/low via word-boundary keyword matching, and publishes to regulatory:actions:v1 via runSeed. Issues: globalThis.fetch used as raw default parameter (AGENTS.md convention), FINRA feed uses plain HTTP, bootstrap hydration not wired in api/bootstrap.js.
tests/regulatory-seed-unit.test.mjs	Thorough unit tests covering entity decoding, HTML stripping, RSS/Atom parsing, deduplication, classification tiers, payload construction, and runSeed wiring; uses vm.runInContext to test pure functions without live network or Redis calls.

Follow-up on the bootstrap thread: I am intentionally leaving regulatory:actions:v1 out of api/bootstrap.js here. That key is an internal seed input for seed-cross-source-signals.mjs, not a client-facing bootstrap source. The UI hydrates crossSourceSignals directly, and that key is already in bootstrap. Adding regulatory:actions:v1 would only increase bootstrap payload size with unused data; it would not change first-load behavior for the cross-source panel.
