AeroVault Security Audit Hardening and Error-Correction Convergence

AeroVault went through an independent dual blind security audit (Claude Opus 4.8 and Codex GPT-5) followed by full remediation and a two-round adversarial controaudit that closed every finding (1 High, 1 Medium, 3 Low, 4 Info, 0 Critical, grade A). In the same pass the error-correction engine became a single audited implementation living in the published aerovault crate (0.6.2) instead of a copy forked into the app, and the My Servers grid got a pair of layout fixes.

Fixed

• No leftover temp or lock after an interrupted vault seal: killing a vault operation mid-seal used to leave a 56-byte .aerovault.lock that blocked the next writer and an 8 GB .aerovault-v3-XXXX plaintext temp beside the target. The container now writes through an auto-deleting temp on the error path, the standalone repair scrubs its temp on the persist-error branch (M1), and a lock orphaned by a crashed run is auto-reclaimed once its recorded owner PID is provably dead, via an atomic rename-aside (M9). (@EhudKirsh, #2)
• AeroVault extract blocks reparse-point escape: extracting a vault could follow a pre-planted intermediate Windows directory junction out of the destination, writing decrypted plaintext into a sibling directory. Each path component is now created refusing to follow a pre-existing reparse point, and the canonical parent is checked to stay inside the destination root (M2).
• correct repair honors an authenticity anchor: a bare repair reconstructed toward whatever hash the sidecar declared, so a planted same-length sidecar could drive it to attacker content. A new --expect-sha256 anchor refuses a sidecar that declares a different hash before any byte is written, on the CLI, the library and the MCP tool (M3).
• AeroVault rejects a forged extension directory at open: the header MAC covered the extension-directory offset and length but not its JSON bytes, so a forged directory is now rejected at open, before any recovery uses it (M4).
• AI local tools resolve absolute POSIX paths on Windows: a /-rooted path was treated as relative on Windows and re-based under the tool working directory; a leading / is now treated as absolute on every operating system.
• IntroHub layout: the My Servers grid now uses container-aware column counts (3 to 9) with a full-height sidebar divider, symmetric grid gutters, and aligned toolbar and cards.

Changed

• Error correction converged onto the aerovault crate (0.6.2): the app's forked standalone .aerocorrect and AeroSync error-correction engine (about 3,500 lines) is removed and replaced by a logic-free re-export of the crate, so the .aerocorrect format has a single audited implementation shared by the desktop app, the CLI and any Rust consumer. A cross-implementation golden keeps the bytes byte-for-byte identical (M7).
• Accurate AeroVault error-correction capability string: the app reported error correction as a Phase 1 stub while shipping live Reed-Solomon error correction; the capability string now reflects the real RS engine (M5).

Security

• AeroVault dual blind security audit, grade A: an independent dual blind audit (Claude Opus 4.8 and Codex GPT-5) plus full remediation and a two-round adversarial controaudit closed 1 High, 1 Medium, 3 Low and 4 Info findings with zero Critical and zero open findings, verified on both the crate and the app. The kill-cleanup pair (M1 and M9) was surfaced by Ehud Kirsh's V3 Beta test pass. (@EhudKirsh, #2)
• DOMPurify updated to 3.4.11: clears a Dependabot advisory (GHSA-cmwh-pvxp-8882, ALLOWED_ATTR pollution via setConfig). A precautionary transitive bump; the affected configuration path is not exercised by AeroFTP.
