Docs and comments only; no behaviour change (no calls swapped, no logic altered). Closes #171.
Part A — corrected each of the ten claims at its current location (the issue's line numbers were stale): snapshot-name guessability (the remote key hashes with no secret, so a guessed hostname+name can be confirmed); blob naming = hex(SHA256(SHA256(uncompressed contents))), stated once in docs/REPOSTRUCTURE.md and referenced from README, ARCHITECTURE, DATAMODEL, database.go, models.go, types.go, packer.go; double-hashing does not hide known content (blob packing does); ChaCha20-Poly1305 not XChaCha20; encryption 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 (README and the snapshot verify --deep help); adding a recipient does not reach existing data; restore examples target a user-owned directory.
Part B — new "Accepted Risks" subsection under the existing Security Considerations in docs/REPOSTRUCTURE.md (seven write-ups), cross-referenced from the README, plus a one-line chunking note by blob_size_limit.
make check green (tests, Docker lint, fmt-check).
Disclosures:
Markdown not run through prettier: repo make fmt is Go-only and the committed docs are not prettier-formatted (proseWrap would reflow whole files); matched each file's existing style instead.
The item-5 cite of vaultik.go:92 is the optional age_secret_key (private key) comment — accurate, and owned by #74 — so left unchanged.
Also aligned a second "cryptographically checks" instance and the manifest comment, same claim family, for consistency.
ExportSnapshotMetadata's header still carries an unrelated stale ".sql"/path description (out of scope here; worth a new issue).

internal/database/database.go line 7 (package doc comment): still states a blob's "filename is derived from their SHA256 hash after compression and encryption." This is exactly the item-2 (Part A) overclaim the PR set out to remove, and it is now the only surviving copy of it in the tree. The real name is hex(SHA256(SHA256(uncompressed blob contents))), computed from the concatenated chunk plaintext before compression and encryption (blobgen.Writer.ContentID → DoubleSHA256 over the uncompressed running SHA-256). The sibling comments in internal/database/models.go, internal/types/types.go, and internal/blob/packer.go were corrected; this one was missed, so a false naming claim remains. Acceptable: correct this comment to the "double SHA-256 of the uncompressed contents, before compression and encryption" wording and point at blobgen.DoubleSHA256 / docs/REPOSTRUCTURE.md, as the sibling files now do.
internal/cli/snapshot.go line ~195 (the snapshot verify command's own Long help text): still tells users to "use --deep to download and cryptographically verify them." Item 8's correction — deep verify detects corruption, not authorship — was applied to the README and the internal comments but not to this user-facing help, which is the most visible place the claim appears and still reads as authenticity/authorship verification rather than an integrity re-hash. Acceptable: reword to match the README wording ("downloads, decrypts, and re-hashes every blob to detect corruption — integrity, not who wrote it"), or at minimum drop "cryptographically verify."

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.

Reworked per review; the two missed locations are corrected.
internal/database/database.go package doc: a blob's name is now stated as hex(SHA256(SHA256(uncompressed blob contents))), computed before compression and encryption, and points at blobgen.DoubleSHA256 and docs/REPOSTRUCTURE.md, matching the sibling comments.
internal/cli/snapshot.gosnapshot verify help: --deep now says it downloads, decrypts, and re-hashes every blob to detect corruption -- integrity, not who wrote it, matching the README; "cryptographically verify" is gone.
