Trust platform v4: reliable releases and decision workspace

[computersciencefreshmen]

Outcome

• adds four-layer admission quality metrics and honest 2026-08-15 README scorecard
• upgrades ten pilot Source Manifests to strict V2 in-progress ledgers
• adds lightweight four-program compare API and decision-first favorites UX
• preserves semantic filters across languages and surfaces Open now / Upcoming routes
• hardens exact-SHA Vercel alias promotion with transactional rollback
• separates backup/restore credentials, versioned raw-v1 R2 checkpoints, readback verification and isolated bulk restore
• preserves D1 Release truth and keeps Shadow compare JSON-primary until parity is proven

Verified

• lint and TypeScript passed
• focused release/manifest/D1/UX tests: 36 passed
• full unit suite before final fail-closed refinements: 656 passed
• data, Manifest and maintenance validators passed after 2026-08-15 stale rollover
• D1 migrations/integrity and four Worker suites passed
• real Catalog + Pipeline R2 readback passed; isolated restore completed in 101.198 seconds with zero FK violations

Safety

• no unreviewed MiniMax inbox/raw files are included
• Production remains on JSON until the planned Shadow gates are satisfied
• GitHub backup/restore/Alias secrets still require secure repository configuration
