📝 WalkthroughWalkthroughThe context gateway now rejects text searches with more than 512 matched paths. Tests cover rejection recording and later valid searches. Investigation prompts now describe the limit error and require narrower searches. ChangesRelation Path Budget
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The PR rejects searches that expand beyond 512 paths, but the current behavior can also leave required typed-search evidence incomplete, preventing some investigations from finishing correctly. The limit is additionally duplicated across the gateway and prompt contract, so future changes could drift; this should be fixed or explicitly accepted before merge. Poem

Add a recovery contract for typed searches.
searchText has no mode, so this branch applies to every search. review-investigation-turn-prompt.ts Line 10 requires typed searches to use the exact query and paths=["."]. Line 12 requires complete relation-context receipts. The prompt only permits narrowing after this error for exploratory searches at Line 14.
A typed search that matches more than 512 files can fail with no permitted way to complete its required evidence. Pass the search purpose and apply this limit only to exploratory searches, or define typed-search failure and obligation-closure behavior.
