* feat(simulation): add keyActorRoles field to fix actor overlap bonus vocabulary mismatch
The +0.04 actor overlap bonus never reliably fired in production because
stateSummary.actors uses role-category strings ('Commodity traders',
'Policy officials') while simulation keyActors uses named geo-political
entities ('Iran', 'Houthi'). 53 production runs audited showed the bonus
fired once out of 53.
Fix: add keyActorRoles?: string[] to SimulationTopPath. The Round 2 prompt
now includes a CANDIDATE ACTOR ROLES section with theater-local role vocab
seeded from candidatePacket.stateSummary.actors. The LLM copies matching
roles into keyActorRoles. applySimulationMerge scores overlap against
keyActorRoles when actorSource=stateSummary, preserving the existing
keyActors entity-overlap path for the affectedAssets fallback.
- buildSimulationPackageFromDeepSnapshot: add actorRoles[] to each theater
from candidate.stateSummary.actors (theater-scoped, no cross-theater noise)
- buildSimulationRound2SystemPrompt: inject CANDIDATE ACTOR ROLES section
with exact-copy instruction and keyActorRoles in JSON template
- tryParseSimulationRoundPayload: extract keyActorRoles from round 2 output
- mergedPaths.map(): filter keyActorRoles against theater.actorRoles guardrail
- computeSimulationAdjustment: dual-path overlap — roleOverlapCount for
stateSummary, keyActorsOverlapCount for affectedAssets (backwards compat)
- summarizeImpactPathScore: project roleOverlapCount + keyActorsOverlapCount
into path-scorecards.json simDetail
New fields: roleOverlapCount, keyActorsOverlapCount in SimulationAdjustmentDetail
and ScorecardSimDetail. actorOverlapCount preserved as backwards-compat alias.
Tests: 308 pass (was 301 before). New tests T-P1/T-P2/T-P3 (prompt/parser),
T-RO1/T-RO2/T-RO3 (role overlap logic), T-PKG1 (pkg builder actorRoles),
plus fixture updates for T2/T-F/T-G/T-J/T-K/T-N2/T-SC-4.

* fix(simulation): address CE review findings from PR #2582
- Add SimulationPackageTheater interface to seed-forecasts.types.d.ts
(actorRoles was untyped under @ts-check)
- Add keyActorRoles to uiTheaters Redis projection in writeSimulationOutcome
(field was stripped from Redis snapshot; only visible in R2 artifact)
- Extract keyActorRoles IIFE to named sanitizeKeyActorRoles() function;
hoist allowedRoles Set computation out of per-path loop
- Harden bonusOverlap ternary: explicit branch for actorSource='none'
prevents silent fallthrough if new actorSource values are added
- Eliminate roleOverlap intermediate array in computeSimulationAdjustment
- Add U+2028/U+2029 Unicode line-separator stripping to sanitizeForPrompt
- Apply sanitizeForPrompt at tryParseSimulationRoundPayload parse boundary;
add JSDoc to newly-exported function
All 308 tests pass, typecheck + typecheck:api clean.
* fix(sim): restore const sanitized in sanitizeKeyActorRoles after early-return guard
Prior edit added `if (!allowedRoles.length) return []` but accidentally removed
the `const sanitized = ...` line, leaving the filter on line below referencing an
undefined variable. Restores the full function body:
if (!allowedRoles.length) return [];
const sanitized = (Array.isArray(rawRoles) ? rawRoles : [])
.map((s) => sanitizeForPrompt(String(s)).slice(0, 80));
const allowedNorm = new Set(allowedRoles.map(normalizeActorName));
return sanitized.filter((s) => allowedNorm.has(normalizeActorName(s))).slice(0, 8);
308/308 tests pass.

Eliminate roleOverlap intermediate array in computeSimulationAdjustment
Problem Statement
roleOverlap is stored as a filtered array but is only ever used as .length (twice). The array itself is never inspected. This creates an unnecessary intermediate allocation.
Current Code
const roleOverlap = actorSrc === 'stateSummary' ? candidateActors.filter((a) => simRoles.has(a)) : [];
details.roleOverlapCount = roleOverlap.length;
// ...
const bonusOverlap = actorSrc === 'stateSummary' ? roleOverlap.length : details.keyActorsOverlapCount;
Proposed Solution
details.roleOverlapCount = actorSrc === 'stateSummary'
? candidateActors.filter((a) => simRoles.has(a)).length
: 0;
const bonusOverlap = actorSrc === 'stateSummary'
? details.roleOverlapCount
: actorSrc === 'affectedAssets' ? details.keyActorsOverlapCount : 0;
This combines with todo #090 (explicit ternary for bonusOverlap).
