Fix memory integrity and introduce project-centered dashboard workflows

[Coding-Dev-Tools]

Description

Concurrent governed writes could create multiple successors and delayed sync publication could restore erased vectors. Packing could also discard repository-specific facts, and synthesis could remove exceptions while still reporting a grounded answer. This change makes those transitions authoritative and gives project-memory tasks a consistent dashboard journey.

• Add atomic, idempotent revisions, schema 18 command receipts/source claims, version conflicts and paginated record lineage. Slow revision preparation happens before the writer reservation. Committed correction/revision/approval retries replay without embeddings and preserve erased/retired-result conflicts. Approval retries retain the original recorded reviewer; malformed lineage metadata cannot crash history or create false links. Completed session promotions/merges replay after closure without embeddings, and project history retains promoted workspace versions without widening caller access. The inspector and editor send the selected project to history and cancel stale responses on context changes; broader roots remain readable within a project.
• Repair indexes from current canonical generations, retaining erasure and retry semantics. Native index failures roll back canonical changes. Cleanup is processed before blocked vector updates, including with a one-attempt budget; failed work remains durable.
• Preserve distinct scoped facts and complete cited evidence units. Answer coverage defaults to unknown, independently of support and citations. Numerical ranking and backend defaults remain unchanged.
• Add portable scoped cursors, bounded file-backed browsing snapshots, durable startup transformation markers, content-free diagnostics and package/build identity.
• Organize Home, Ask, Library and Connections around project context, visible ownership, atomic editing and history. Preserve drafts and independent answer/preview retries. Pause hidden Explore views through the existing renderer APIs; retain CSP, themes and renderer algorithms.
• Add strict corpus, paired-result and complete-engine capacity measurement contracts. Refresh the measured offline payload artifact and visible figures without weakening the evidence tolerance. These tools do not establish 100k capacity or independent task quality.

The original checkout's active graph/layout work stays separate. The implementation and remaining dependency order are recorded in docs/REWORK_EXECUTION.md.

Type

• Bug fix
• New additive interfaces
• Documentation and evaluation infrastructure
• Packaging gate coverage

Verification

• All checks passed on 31da32c06a5ade989608504472e00dfca6f13f94: CodeQL and ci. This includes the NumPy-only Python 3.9 floor, full Python 3.10–3.14 stacks, encryption matrix, coverage, browser, packaging, Docker, type and hygiene gates. The Python 3.12 full suite passed 5,067 tests with 18 optional/platform skips.
• The approval, lineage, session-retry, lost-response/embedding and erasure-starvation counterexamples failed on their prior source and pass after the fixes. Additional focused governance, poisoning, inspection, REST/history and workspace-isolation suites passed; independent review found no remaining blocker in those changes.
• Seven documented offline evaluation gates, Ruff, Pyright, commercial manifest, generated MCP contract, packaged CSP assets and whitespace checks passed.
• Complete browser CI passed. The final focused history/workflow run passed 25 checks, including real-service project isolation, stale request cancellation and correction/history smoke in Firefox and WebKit. Human agent restart and screen-reader testing are not claimed.
• Built wheel and sdist passed archive verification. A fresh Windows Python 3.12 environment containing only NumPy and the installed wheel migrated a real schema-17 fixture, restarted, retried an atomic revision, rejected conflicting reuse, and paged preserved history. Database/backup integrity, all new assets, dependency compatibility and all 16 console help entrypoints passed on the wheel rebuilt from this exact commit.

Migration and remaining release gates

Schema 18 uses the verified pre-migration backup path. Never downgrade a migrated live database in place: restore into a separate fenced location and reconcile later erasures/revocations before serving it. Production restore/cutover, both physical capacity targets, the independent 400-task corpus, human usability and the consented pilot remain open. Paid evaluations require the separate concrete proposal's approval. No merge, release or deployment is included.
