Elie Habib 01f6057389 feat(simulation): MiroFish Phase 2 — theater-limited simulation runner (#2220 )

* feat(simulation): MiroFish Phase 2 — theater-limited simulation runner

Adds the simulation execution layer that consumes simulation-package.json
and produces simulation-outcome.json for maritime chokepoint + energy/logistics
theaters, closing the WorldMonitor → MiroFish handoff loop.

Changes:
- scripts/seed-forecasts.mjs: 2-round LLM simulation runner (prompt builders,
  JSON extractor, runTheaterSimulation, writeSimulationOutcome, task queue
  with NX dedup lock, runSimulationWorker poll loop)
- scripts/process-simulation-tasks.mjs: standalone worker entry point
- proto: GetSimulationOutcome RPC + make generate
- server/worldmonitor/forecast/v1/get-simulation-outcome.ts: RPC handler
- server/gateway.ts: slow tier for get-simulation-outcome
- api/health.js: simulationOutcomeLatest in STANDALONE + ON_DEMAND keys
- tests: 14 new tests for simulation runner functions

* fix(simulation): address P1/P2 code review findings from PR #2220

Security (P1 #018):
- sanitizeForPrompt() applied to all entity/seed fields interpolated into
  Round 1 prompt (entityId, class, stance, seedId, type, timing)
- sanitizeForPrompt() applied to actorId and entityIds in Round 2 prompt
- sanitizeForPrompt() + length caps applied to all LLM array fields written
  to R2 (dominantReactions, stabilizers, invalidators, keyActors, timingMarkers)

Validation (P1 #019):
- Added validateRunId() regex guard
- Applied in enqueueSimulationTask() and processNextSimulationTask() loop

Type safety (P1 #020):
- Added isOutcomePointer() and isPackagePointer() type guards in TS handlers
- Replaced unsafe as-casts with runtime-validated guards in both handlers

Correctness (P2 #022):
- Log warning when pkgPointer.runId does not match task runId

Architecture (P2 #024):
- isMaritimeChokeEnergyCandidate() accepts both flat and nested topBucketId
- Call site simplified to pass theater directly

Performance (P2 #025):
- SIMULATION_ROUND1_MAX_TOKENS raised 1800 to 2200
- Added max 3 initialReactions instruction to Round 1 prompt

Maintainability (P2 #026):
- Simulation pointer keys exported from server/_shared/cache-keys.ts
- Both TS handlers import from shared location

Documentation (P2 #027):
- Strengthened runId no-op description in proto and OpenAPI spec

* fix(todos): add blank lines around lists in markdown todo files

* style(api): reformat openapi yaml to match linter output

* test(simulation): add flat-shape filter test + getSimulationOutcome handler coverage

Two tests identified as missing during PR #2220 review:

1. isMaritimeChokeEnergyCandidate flat-shape tests — covers the || candidate.topBucketId
   normalization added in the P1/P2 review pass. The existing tests only used the nested
   marketContext.topBucketId shape; this adds the flat root-field shape that arrives from
   the simulation-package.json JSON (selectedTheaters entries have topBucketId at root).

2. getSimulationOutcome handler structural tests — verifies the isOutcomePointer guard,
   found:false NOT_FOUND return, found:true success path, note population on runId mismatch,
   and redis_unavailable error string. Follows the readSrc static-analysis pattern used
   elsewhere in server-handlers.test.mjs (handler imports Redis so full integration test
   would require a test Redis instance).

Redis key strings duplicated between TS handler and MJS seed script

Problem Statement

SIMULATION_OUTCOME_LATEST_KEY = 'forecast:simulation-outcome:latest' is defined independently in both server/worldmonitor/forecast/v1/get-simulation-outcome.ts and scripts/seed-forecasts.mjs. The same duplication exists for SIMULATION_PACKAGE_LATEST_KEY. server/_shared/cache-keys.ts (referenced in the worldmonitor-bootstrap-registration pattern) exists for exactly this purpose: shared Redis key constants that TypeScript handlers and seed scripts need to agree on. A future rename in one file without the other produces a silent miss where the handler reads an empty key forever.

Findings

F-1:

// server/worldmonitor/forecast/v1/get-simulation-outcome.ts line 10
const SIMULATION_OUTCOME_LATEST_KEY = 'forecast:simulation-outcome:latest';

// scripts/seed-forecasts.mjs line 35
const SIMULATION_OUTCOME_LATEST_KEY = 'forecast:simulation-outcome:latest';
// Two independent definitions with no enforcement of consistency

F-2: Same pattern for SIMULATION_PACKAGE_LATEST_KEY between get-simulation-package.ts and seed-forecasts.mjs.

Proposed Solutions

Option A: Move keys to `server/_shared/cache-keys.ts`, import in handler (Recommended)

// server/_shared/cache-keys.ts — add:
export const SIMULATION_OUTCOME_LATEST_KEY = 'forecast:simulation-outcome:latest';
export const SIMULATION_PACKAGE_LATEST_KEY = 'forecast:simulation-package:latest';

// server/worldmonitor/forecast/v1/get-simulation-outcome.ts — replace local const:
import { SIMULATION_OUTCOME_LATEST_KEY } from '../../../_shared/cache-keys';

The seed script (scripts/seed-forecasts.mjs) keeps its own definition since it's a standalone MJS module that cannot import from TypeScript source. But the TypeScript handler becomes the downstream consumer of a canonical definition, making renames TypeScript-checked.

Effort: Small | Risk: Low

Option B: Add a comment cross-referencing both locations

Not a fix, but documents the relationship so a human renaming one knows to update the other. Use as a stopgap if Option A causes import complexity.

Acceptance Criteria

SIMULATION_OUTCOME_LATEST_KEY exported from server/_shared/cache-keys.ts
get-simulation-outcome.ts imports from cache-keys.ts instead of local const
SIMULATION_PACKAGE_LATEST_KEY moved simultaneously
get-simulation-package.ts updated to import from cache-keys.ts
TypeScript compilation clean after change

Technical Details

Files: server/worldmonitor/forecast/v1/get-simulation-outcome.ts:10, server/worldmonitor/forecast/v1/get-simulation-package.ts:~10, server/_shared/cache-keys.ts
Scripts keep their own definitions (they're standalone MJS — can't import from TS source)
