 # MailVault Collection Profiler v0.1.0-alpha.6
 
-Final feature-complete prerelease combining incremental profiling, continuous watch, crash-safe
-resume, content-addressed file/format reuse, update-aware full-snapshot metadata reconciliation,
-stable archive identity migration and bounded snapshot retention.
+## Release status
 
-Publication requires the Windows quality gate and the real-archive initial/no-change/delta/crash/soak
-acceptance scripts to pass. After Alpha 6 only maintenance, security and compatibility fixes are in scope.
+Alpha 6 is the final feature-complete prerelease of the MailVault Collection
+Profiler continuous-profiling runtime.
+
+It is intended for technical evaluation and controlled profiling of existing
+MailVault schema-v3 archives on Windows x64.
+
+After Alpha 6, only maintenance, security and compatibility corrections are in
+scope for this prerelease line.
+
+## Implemented capabilities
+
+- read-only MailVault schema-v3 preflight;
+- SQLite Online Backup source snapshots;
+- stable collection binding and archive identity aliases;
+- initial, incremental and rebuild generations in one workspace;
+- update-aware full metadata reconciliation;
+- cumulative SHA-256 content projection;
+- selective reuse of successful unchanged file-stat results;
+- retry of unavailable, missing, mismatched and I/O-error objects;
+- exact-format identification with Siegfried 1.11.6 and PRONOM v124;
+- content-addressed reuse for duplicate attachment SHA-256 values;
+- same-run resume after interruption in source snapshot, metadata inventory,
+  file-stat and format-identification stages;
+- continuous watch with stable source-revision polling and retry backoff;
+- bounded successful-snapshot retention and orphan cleanup;
+- automatic workspace schema migration from version 6 to version 7.
+
+## Runtime validation
+
+The Alpha 6 candidate passed:
+
+- complete Windows quality gate;
+- Rust formatting, strict Clippy and all Rust tests;
+- TypeScript, Vite and native Tauri validation;
+- MSI and NSIS installer builds;
+- real-archive initial profile;
+- immediate no-change incremental profile;
+- real IMAP delta ingestion;
+- duplicate-SHA occurrence reuse without duplicate content objects;
+- forced termination and same-run resume in all four processing stages;
+- 100-generation bounded-growth soak;
+- source-revision v3 watch stability;
+- independent rebuild equivalence;
+- canonical MailVault source immutability checks.
+
+## Safety and privacy
+
+The profiler treats the MailVault archive as read-only.
+
+Profiling data, checkpoints, findings and retained snapshots are written only to
+the selected profiler workspace. The profiler does not execute attachments,
+modify MailVault records or repair source archive files.
+
+Public release assets do not include runtime databases, archive payloads, logs,
+private screenshots, acceptance workspaces or real-archive evidence.
+
+## Compatibility boundary
+
+- Windows x64;
+- MailVault schema version 3;
+- profiler workspace schema version 7;
+- Siegfried 1.11.6;
+- PRONOM signature version 124;
+- NSIS and MSI installer formats.
+
+Newer unsupported MailVault schemas fail closed during preflight.
+
+## Known limitations
+
+- installers are currently unsigned and Windows may display a publisher or
+  SmartScreen warning;
+- unavailable or missing source objects are reported and retried but are not
+  repaired by the profiler;
+- exact-format identification may legitimately classify unsupported content as
+  unknown;
+- OCR, text extraction, embeddings, vector databases, RAG, LLM classification,
+  procurement semantics, RMS integration, attachment execution and container
+  expansion are outside this profiler;
+- Alpha 6 remains a prerelease and should not be treated as a substitute for
+  independent backups of the MailVault archive or profiler workspace.
+
+## Upgrade and rebuild
+
+Back up an existing profiler workspace before opening it with Alpha 6.
+
+Supported version-6 workspaces are migrated to workspace schema version 7. For
+independent verification or when replacing an experimental workspace, create a
+new workspace and run a clean rebuild against the same read-only MailVault
+archive.
+
+Do not place the profiler workspace inside the MailVault archive.
+
+## Artifact verification
+
+After downloading the release assets and `SHA256SUMS.txt`, run:
+
+```powershell
+Get-Content .\SHA256SUMS.txt
+
+Get-ChildItem -File -Include *.exe,*.msi |
+ForEach-Object {
+    Get-FileHash `
+      -LiteralPath $_.FullName `
+      -Algorithm SHA256
+}
+```
+
+Compare every calculated SHA-256 value with `SHA256SUMS.txt`.
+
+For repository provenance verification:
+
+```powershell
+Get-ChildItem -File -Include *.exe,*.msi |
+ForEach-Object {
+    gh attestation verify `
+      $_.FullName `
+      --repo FireXCore/MailVault-Collection-Profiler
+}
+```
+
+Installers must remain byte-identical to the assets referenced by the published
+checksum manifest and provenance attestations.
