Overview
| Comment: | Add the storage capability seam and its deterministic fault simulator: a narrow StorageFile interface (append/pread/sync/size/truncate), an in-memory FaultyFile that injects torn and short writes, lost fsync tails, crash-restart, and payload-derived bitflips from the run seed, and a simulation sweep asserting crash-recovery truncates a torn tail to the last valid frame and never reads corruption as data |

| 21:53 | Add the LogStore: a framed append-only content-addressed object log with a 64-byte header and per-frame length, kind, hash, and crc, exposing intern, put, content, hash lookup, and commit over the storage capability, rebuilding its hash-to-offset index by scanning on open and truncating a torn tail, and driven through the fault simulator by the storage sweep check-in: c1e15637a3 user: dmestas tags: storage | |
