MailVault Collection Profiler v0.1.0-alpha.4

MailVault Collection Profiler v0.1.0-alpha.4

Alpha 4 adds exact technical file-format identification to the existing read-only physical profiler.
It does not create a second archive and does not add OCR or procurement classification.

Highlights

• pinned Siegfried 1.11.6 + PRONOM v124 Windows sidecar;
• verified release-asset acquisition and local tool/signature manifest;
• PUID, format/version, MIME, evidence basis and all alternative matches;
• deterministic primary assertion with explicit ambiguity preservation;
• safe extension-evidence aliases and honest Not checked state;
• bounded batch runner with timeout, output limits and adaptive failure isolation;
• durable format checkpoints and same-fingerprint resume;
• exclusive format-stage workspace lock;
• desktop Exact formats dashboard and CLI commands;
• profiler schema migration 6;
• sanitized aggregate format summary schema 2;
• updated English/Persian docs and publication-ready screenshots.

Security and privacy

• MailVault remains read-only.
• Sidecar resources are versioned and hashed.
• Containers are not expanded.
• No attachment is executed or rendered.
• Raw profiler databases, paths, filenames and progress evidence remain private.

Upgrade

Back up an Alpha 3 workspace before using --allow-migration. Migration 0006 preserves existing
objects, occurrences, findings and review history while adding exact-format tables and indexes.

Validation status

Static/frontend gates and migration of a private real Alpha 3 workspace passed. Full Rust semantic
compilation, Windows installer creation and the first private real-archive Siegfried run are required
before publishing runtime-green performance claims. See
Alpha 4 validation evidence.

Known limitations

• no physical-profile pause/cancel/resume;
• no container expansion;
• no JHOVE validation;
• no extraction, OCR or preview;
• no document classification or RMS integration;
• unsigned Windows installers;
• no public real-archive format distribution is bundled in this source candidate.

MailVault Collection Profiler v0.1.0-alpha.3

MailVault Collection Profiler 0.1.0-alpha.3

This development pre-release adds durable workspace reopening and append-only findings review to the existing read-only physical inventory pipeline.

Highlights

• Inspect and reopen existing profiler workspaces after application restart.
• Explicit compatibility and migration confirmation before opening older workspaces.
• Retained SQLite backup before workspace schema migration.
• Run catalog for completed, failed and interrupted profiling records.
• Browse previous inventory, findings and object details without rerunning profiling.
• Single-writer workspace lock with read-only fallback for concurrent instances.
• Append-only review history with SHA-256 event-chain validation.
• Review statuses: acknowledged, expected, needs investigation and resolved externally.
• Required review notes for investigation and externally resolved decisions.
• Findings separated into attention, informational, reviewed and all views.
• Sanitized JSON and CSV exports that exclude paths, filenames, email addresses and review notes.
• CLI commands for workspace inspection, run browsing, review and export.

Safety boundary

• MailVault source databases and objects remain read-only.
• Source snapshots and original runtime evidence are not changed by review activity.
• Existing profiler databases are never created implicitly during reopen.
• Newer or corrupted workspaces fail closed.
• Review history integrity failure disables writes but leaves browsing available.

Upgrade

Opening an alpha.2 workspace requires an explicit migration to workspace schema 5. A pre-migration backup is retained under backups/. Do not delete the backup until the migrated workspace has been validated.

Known limitations

• Interrupted profiling cannot yet resume from the desktop UI.
• Pause and cancellation controls are not exposed.
• Full payload fixity, PRONOM/Siegfried identification, JHOVE, container expansion, OCR and semantic classification remain deferred.
• Windows installers remain unsigned.

Validation completed

The Windows release candidate passed Rust formatting, Clippy with warnings denied, 28 Rust tests,
TypeScript type-checking, the Vite production build, native Tauri desktop compilation, documentation
privacy checks, workspace restart/reopen acceptance, Windows lock fallback, append-only review
integrity and sanitized export acceptance.

A controlled real-archive run completed with 17,296 messages, 54,450 MIME parts, 13,684 content
objects, 1,484 findings, 0 errors, 2 warnings, 1 missing object and 0 size mismatches. Source and
snapshot aggregate metrics matched, and the MailVault source was not modified. Raw runtime evidence
remains private; only sanitized aggregate evidence may be published.
