clawbot	dd7a610c23	Mark a snapshot complete only after its metadata export succeeds (closes #177) ... finalizeSnapshotMetadata marked the snapshot complete and then exported its metadata. A crash after completion but before/during the export left the local index showing the snapshot complete while the destination had no manifest or database, and PruneDatabase (which drops only NULL completed_at rows) kept it: a silently unrestorable snapshot. Reorder so completion is recorded last. CompleteSnapshot is split into PopulateSnapshotBlobs (before the export) and MarkSnapshotComplete (after it). An interrupted export now leaves the snapshot incomplete, so the next run PruneDatabase drops it and re-backs-up the data; the reverse tiny window leaves a restorable snapshot the index reports honestly as remote-only. Update REPOSTRUCTURE.md guarantee 4 and the ARCHITECTURE.md flow. Add a fault-injection test driving the full create path. Model: opus-4-8	2026-09-22 20:00:41 +02:00
clawbot	1548c0f933	Correct the security claims in docs and comments, and record the accepted risks (closes #171) ... Docs and comments only; no behaviour change. Corrects ten overclaims the security review found: snapshot names are hashed but the hash uses no secret, so a guessed hostname and name can be confirmed; a blob is named by hex(SHA256(SHA256(uncompressed contents))), stated once in docs/REPOSTRUCTURE.md and referenced elsewhere; double hashing does not hide known content (blob packing does); age uses ChaCha20-Poly1305, not XChaCha20; encryption is required, not optional; a snapshot is marked complete before its metadata is uploaded; the export comment now matches its only caller; deep verify detects corruption, not authorship; adding a recipient does not reach existing data; restore examples target a user-owned directory. Adds an Accepted Risks subsection under Security Considerations with the seven documented risks, cross-referenced from the README. Model: opus-4-8	2026-09-22 19:28:31 +02:00
clawbot	86361c8b50	Fail closed on unreadable manifests instead of losing blobs (closes #157) ... Prune learned which blobs are in use by reading every snapshot's manifest, but merely logged and skipped one it could not download or decode. Blobs referenced only by that snapshot then looked unreferenced and were deleted, with a zero exit -- and snapshot create --prune runs this unattended. collectReferencedBlobs now errors, naming the remote key, so prune deletes nothing and exits non-zero. Manifest generation likewise skipped a blob whose lookup failed or was missing, yielding a manifest short of what the snapshot needs; it now fails. Deep verify only warned when the manifest omitted a database blob; it now fails on any divergence. Docs corrected. Model: opus-4-8	2026-09-22 11:45:30 +02:00
clawbot	753bc3ef60	Correct remote layout and privacy docs for hashed snapshot keys (closes #67) ... Three documents showed the remote layout with a plaintext snapshot ID as the metadata directory name, and docs/REPOSTRUCTURE.md blamed those IDs for the observable backup time. The store actually names each metadata directory with a one-way hash of the ID, so hostname and snapshot name are not visible; the backup time is, through the plaintext timestamp in the manifest, which is accepted behaviour. README, ARCHITECTURE.md, docs/DATAMODEL.md and docs/REPOSTRUCTURE.md now show the hashed layout, the derivation is documented once, and the privacy section lists what the unencrypted manifest exposes. Two code comments that claimed the timestamp was hidden are corrected. No behaviour change. Judgement call: docs/DATAMODEL.md was not named in the issue but had the same error. model: claude-opus-4-8 (implementation, review); claude-fable-5-1 (merge)	2026-09-21 19:24:44 +02:00
sneak	9f2d722734	Refresh docs: remove PROCESS.md, fix snapshot ID format, document pre-1.0 migration policy	2026-05-01 07:07:18 +02:00
sneak	fb220685a2	Fix manifest generation to not encrypt manifests ... - Manifests are now only compressed (not encrypted) so pruning operations can work without private keys - Updated generateBlobManifest to use zstd compression directly - Updated prune command to handle unencrypted manifests - Updated snapshot list command to handle new manifest format - Updated documentation to reflect manifest.json.zst (not .age) - Removed unnecessary VAULTIK_PRIVATE_KEY check from prune command	2025-07-26 02:54:52 +02:00
