• 🔴 (17:58) User required that recovery never recovers a live execution lease.
• 🔴 [enforced-workflow] (17:58) User required package tests to be run from the relevant package directory and never from the repository root.
• 🟡 (17:57) Investigation found 17 execution-phase references in packages/core/test/session-projector.test.ts: "unknown" at lines 94, 114, 173, 252, 299, 495, and 875; "ready" at lines 206, 336, 384, 390, 536, 635, 696, 789, and 907; "safe" as const at line 587.
• 🟡 (17:58) packages/core/test/session-projector.test.ts was modified while extending recovery/projector coverage; its existing tests include "atomically reconciles one abandoned execution into one continuation", "recovers each abandoned execution once across repeated startup scans", and "never recovers a live execution lease".
• 🟡 (17:58) Effect implementation guidance was consulted: use current Effect v4/effect-smol source and nearby repository patterns; prefer Effect.gen(function* () {}), Effect.fn("Name") or Effect.fnUntraced(...), Effect Schema, branded IDs, Schema.TaggedErrorClass, explicit layers, testEffect(...) for Effect services, and it.live(...) for real external resources; avoid any, non-null assertions, unchecked casts, and stale APIs.
• 🟡 (17:59) Focused package tests passed: 139 pass, 0 fail, 411 expect() calls across 3 files in 14.49s using Bun 1.3.14.
• 🟡 (17:59) packages/core/src/session/recovery.ts was modified after the focused test run; no final validation result for that subsequent modification was shown.
