…newer V1 threads Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
statev2.sqlite left behind by a preview, rollback or channel switch was reused forever, so projects and threads created in V1 afterwards never appeared. When V1 has a project or thread missing from, or newer than, the copied legacy tables and the V2 store holds no V2-native events, move the stale copy (and its WAL/SHM) aside and snapshot V1 again. A V2 store with V2 work is kept, with a warning that newer V1 data is not imported. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…ontent The V2-work check now looks at content instead of events: threads or messages beyond the copied legacy tables, projects missing from V1, or scheduled tasks missing from V1. Server-written events such as auto-settle no longer block a re-seed, and event-less scheduled tasks are kept. The replacement moved out of SqlitePersistence.layerConfig into replaceStaleV2Database, called right after the server acquires ownership, so CLI processes never move the live database. It keeps one statev2.sqlite.stale backup and renames -wal/-shm before the main file. Docs describe the re-copy. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A device revoked or a pairing link closed in V2 now counts as V2 work, so a re-copy cannot reopen it from V1. The stale copy is checkpointed before it is moved, and a failed move logs a warning and keeps the existing database instead of failing startup. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Disabling or deleting an imported V1 task in V2 does not count as V2 work, so when V1 later gains a newer thread, replaceStaleV2Database replaces the database and restores the task's original enabled state. hasIdsBeyond only detects task IDs added in V2; compare task updates and removals too before replacing the copy.

Because the replacement is heuristic and can discard or restore stored user state, the change warrants human review. Needs human approval because:

Explanation
For
#15017, the implementation detects newer V1 project or thread shells by ID andupdated_at. It re-copies V1 when the V2 copy has no V2-specific threads, messages, projects, scheduled tasks, or protected V2 auth revocations. It preserves divergent V2 data and logs a warning. The server calls this check after ownership acquisition, while CLI initialization keeps seed-only behavior. Tests cover new and updated V1 data, V2 keep cases, WAL checkpointing, backup retention, and repeated startup.

Log inspection failures before keeping the V2 copy.
An inspection failure does not prove that the V2 copy is stale, so retaining it is a safe fallback. However, the current fallback is silent. If the copy is stale, newer V1 projects, threads, messages, or status changes can remain unavailable until a later inspection succeeds. This is an operational data-freshness risk, not only a logging cleanup.

Rewrap the paragraph; Line 8 exceeds the formatter width.
The other lines in this paragraph wrap at about 100 characters. Line 8 is about 113 characters because the new text was joined to the existing sentence. The coding guidelines require markdown edits to be formatter-clean, so vp check will likely fail.
Run vp check --fix and commit the reflowed paragraph.

Document authentication state as V2 work.
The current guard preserves V2-revoked sessions and revoked or consumed pairing links. The paragraph’s exhaustive-looking V2 work list omits this security invariant. Without it, a maintainer may remove the guard as unnecessary. This is a documentation-contract violation and a future security-regression risk, not a current authorization bypass.

Problem
V2 copies V1's
state.sqliteintostatev2.sqliteonce, then reuses that file on every later start. If the copy came from a preview build, a nightly run once, a rolled-back server update, or a channel switch back to V1, everything the user did in V1 afterwards never shows up in V2. Missing items include new projects, threads and messages. Restarting does not help and nothing is logged.Repro on
main(8d3b061121), with real apps sharing one T3 home:t3@0.0.45(V1) with--auto-bootstrap-project-from-cwd projAcreates project A and its thread.statev2.sqlite.t3@0.0.45runs again fromprojBand creates project B and its thread.Change
The server now replaces a stale copy when two things are both true:
updated_at.When both hold, the server moves the copy aside to
statev2.sqlite.staleand copies V1 again.What counts as V2 work. Work is judged by content, not by events, because the server writes its own events within a minute of starting (auto-settle, PR sync). Any of these counts:
If V2 holds work, it is kept and the server logs a warning.
Where it runs. Only the server does this, right after it takes the T3-home ownership lock (
replaceStaleV2Databaseinserver.ts). CLI processes that open persistence, such ast3 pairandt3 project, keep main's seed-only-when-missing behaviour, so they never move a database another process has open.How the copy is moved. The server checkpoints the WAL into the copy, then renames the main file. Any failure logs a warning and keeps the existing database, so a locked file never blocks startup. Exactly one backup is kept.
state.sqliteis only ever opened read-only.The user and internal migration docs now describe when V2 copies V1 again and what that copy replaces.
