Summary

  • recover workspace convergence state written by Engine 1.1.0-rc.3 using its exact persisted layout
  • migrate recovered state to a fixed V3 persisted layout without discarding the original ciphertext before verification
  • keep rc.4 V3 records readable and document the recovery guarantee

Affected users who have not reset or deleted their local data can upgrade to the fixed build and recover automatically.

Validation

  • cargo test -p uc-infra --lib db::repositories::workspace_convergence_store::tests --locked (14 passed)
  • cargo metadata --locked --format-version 1
  • cargo check --workspace --all-targets --locked
  • cargo fmt --all -- --check
  • node scripts/architecture/check-engine-repository.mjs
  • git diff --check origin/main...HEAD
  • full workspace tests passed before rebasing onto the latest main; the focused recovery tests and required repository checks were rerun after rebase

Verification boundary

  • physical desktop upgrade was not run in this checkout

Summary by CodeRabbit

  • Bug Fixes

    • Improved compatibility when reading and migrating legacy workspace convergence state.

    • Improved handling of interrupted, incomplete, or invalid migrations with safer recovery decisions.
    • Preserved newer convergence data during version upgrades.
    • Improved recovery of legacy membership information.
  • Documentation

    • Updated architecture documentation with migration behavior and recovery guidance.

📝 Walkthrough

Walkthrough

The change adds workspace convergence recovery for missing persisted state. It updates origin detection, state loading, legacy marker recovery, repository provenance recovery, diagnostics wording, tests, and architecture and planning records.

Changes

Workspace convergence recovery

Layer / File(s) Summary
Origin and presence plumbing
crates/uc-application/src/space/convergence/mod.rs, crates/uc-engine/src/assembly/sync_engine.rs, crates/uc-application/src/space/convergence/membership/bootstrap.rs, crates/uc-application/src/space/convergence/membership/tests.rs
from_version_transition now treats any prior version as an upgrade. State loading now reports persisted-state presence. Sync assembly passes the derived origin. Legacy marker recovery now persists missing state when migration is already marked. Tests cover upgraded and fresh installations.
Repository provenance recovery
crates/uc-infra/src/db/repositories/workspace_convergence_store.rs
V2 and V3 conversions now recover legacy migration provenance from persisted flags and durable historical evidence. RC4 fixtures, RC3 normalization, and recovery and fail-closed tests cover the new conversion rules.
Diagnostics and records
crates/uc-application/src/space/convergence/projection/current_scope.rs, docs/architecture/architecture-bible.md, .planning/*
Current-scope warnings now use the shared unavailable message. The architecture bible records the recovery rules. The planning files record the recovery work item, findings, progress, and task plans.

Estimated code review effort: 4 (Complex) | ~50 minutes

Merge Risk: 🟡 Moderate · up to e49e9

The migration can currently mark unavailable V2 workspace records as legacy, allowing them to take a legacy peer-scope path instead of remaining unavailable. This may cause incorrect workspace convergence for affected users, so the PR is not merge-ready until the fail-closed checks are applied consistently.

Synchronize the missing-state verification records.

The progress log still lists the broader suite and mandatory repository checks as the next step. The task plan still marks Phase 4 in_progress with unchecked verification items.

Keep V2 provenance recovery fail-closed.

Line 72 marks every V2 state without an applied history as legacy. This includes removed, recovery-required, and integrity-failed states.

The V3 conversion at lines 407-416 correctly requires durable evidence before it sets this marker. Apply the same checks to V2 conversion. Update expected_rc3_state to match. Add V2 cases for removed, missing identity, missing peers, recovery-required, and failed states.

Otherwise, the migrated V3 record persists migrated_from_pre_adr_020 = true. current_scope can then use the legacy peer-scope fallback for a state that must remain unavailable.

Proposed fix
-        let migrated_from_pre_adr_020 = state.migrated_from_pre_adr_020
-            || state
-                .membership_reconciliation
