Problem

The dev database seed (vp run migrate-dev-db, and the first vp run dev in a worktree) copied kept threads' projection payloads verbatim. That copy included each pull request link's active watch. On a stopped, unsettled thread the dev server's PullRequestWatchReactor then swept that watch at startup and read the pull request from the host with this machine's credentials. A change in checks, comments or merge state would wake the thread and start its provider in the real worktree, while the live install's agent is doing the same work.

Reproduced on main a9e709f15f with a synthetic source database (one stopped thread, one PR link with an active watch): after the seed, $.pullRequests[0].watch is still set, and the seeded dev server logs pull request watch check failed … getChangeRequest about one second after Listening.

Change

pruneSnapshot in apps/server/scripts/migrate-dev-db.ts now rebuilds $.pullRequests without $.watch on every kept thread whose links carry a watch, in the same transaction that clears the rest of the pending work. The links themselves (URL, snapshot, stack, endedWatch) stay, so the UI still shows the thread's pull requests.

Scope and approval

Fixes #32736

AGENTS.md promises that the seed drops pending work "so your dev server never runs the developer's agents". This change brings the seed back in line with that promise.

Verification

• vp test run apps/server/scripts/migrate-dev-db.test.ts: 9/9 pass, also on head de4008a (main merged in). The extended keeps stopped and settled thread families and clears pending work gives stopped-thread a watched PR link and asserts the link's URL survives while its watch is gone. On main it fails with copied pull request links keep their history but stop being watched (the watch JSON is still present).
• vp run check:changed: pass on de4008a (format, lint, knip, typecheck, tests).
• Runtime transcript (synthetic database only). Each side ran the real CLI and then a seeded dev:server first start with HOME pointed at a synthetic home:

• Mixed links and untouched controls (real migration CLI on a synthetic source, same driver at merge-base f12bb62 and head f219ff9, Node 26.12.1 / SQLite 3.54.0). Kept threads: a stopped root with 13 mixed links, a watched fork and a watched settled root. Before: all 9 watches survive the seed. After: all 9 are gone, and the 17 links keep their order, count, snapshot, stack, endedWatch and other fields. Control threads (no pullRequests, an empty array, unwatched links with endedWatch) come out with payload_json byte-identical to the source on both sides. The source database is unchanged after each run. driver.mjs, assertions.mjs, raw-before.json, raw-after.json, transcript.md.
• Review on de4008a: two independent reviewers, round 1, both no findings. Both checked mixed, empty, missing and legacy link shapes against SQLite 3.54.0 and timed the json_each rewrite as linear: 2.6 ms for one row with 3000 links; malformed JSON is rejected in under 1 ms, and the existing prune query already rejects it.
• Proof audit on de4008a: sufficient, nothing to recapture (matrix). The transcript above was taken on 9f04b77. Since then, the merges from main have not touched migrate-dev-db.ts, its test, scripts/dev-runner.ts, or the reactor's watch selection.
• Not checked: a real wake against a live PR. The synthetic home has no GitHub credential, so the "before" sweep stops at the host read. The reactor reaching the host read is the step this fix removes.

Approvability

Verdict: Approved at 9f04b77

Macroscope's review found this PR approvable — Development database seeds now strip active pull-request watches while retaining the pull-request links. The change affects only the generated development copy and leaves the read-only source unchanged.

No code changes detected at de4008a. Prior analysis still applies.

Full details: Title check

Explanation

The title "fix(server): dev database seed drops active pull request watches" matches the main change. The PR changes pruneSnapshot in migrate-dev-db.ts to remove the watch property from pull request links in kept threads during dev seeding. It uses a conventional commit prefix and names the component, the seed, and the behavior. It is 64 characters and 9 words, which is concise. The title is not vague and does not describe anything absent from the changeset.

Full details: Linked Issues check

Explanation

Issue #32736 requires the dev seed to keep pull request links as history and drop their active watches on kept threads. The diff at apps/server/scripts/migrate-dev-db.ts (pruneSnapshot) adds an UPDATE on orchestration_v2_projection_threads. It runs inside the existing transaction that clears pending work. It sets $.pullRequests to json_group_array(json_remove(link.value, '$.watch')) for every thread whose links carry a non-null watch. The url, snapshot, stack and endedWatch fields stay in place, which matches the issue's expected behavior. The test diff in migrate-dev-db.test.ts gives stopped-thread a watched PR link. It asserts that the URL survives and that $.pullRequests[0].watch is null after the seed. That is the fixture repro described in the issue. Residual uncertainty: the seed keeps orchestration_events for kept threads. The diff does not show whether a projection rebuild from those events could restore a watch. The runtime transcript used a synthetic database with no events, so it does not cover this path. The verdict rests on the payload copy that the issue describes.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff against merge base a9e709f has two files. apps/server/scripts/migrate-dev-db.ts gains one UPDATE statement in pruneSnapshot, which is the seed path named by #32736. apps/server/scripts/migrate-dev-db.test.ts changes the stopped-thread fixture to carry a watched PR link and adds an assertion on its URL and watch. Both changes support the objective of dropping watches from seeded threads. No unrelated runtime, reactor or UI code changed. The watch is stripped from all kept threads, including settled and running ones. The issue scope permits this because the seed goal is to drop active watches, and the reactor already ignores watches on settled threads.

Full details: Description check

Explanation

The description covers the problem, change, scope, and focused verification in detail. It links the issue, but does not include an explicit maintainer approval comment or name the AI model and harness, as requested by the template. These omissions do not make the otherwise complete description fail.

Thanks. Skipping both nitpicks:

• History fields: the rewrite calls json_remove(link.value, '$.watch') on each element, so it cannot drop snapshot, stack or endedWatch. The test already asserts that the link survives (its URL is checked), so a rewrite that dropped the whole link would fail.
• Multiple links: the UPDATE rebuilds the array from json_each over every element, ordered by key. No code path handles only the first link.

Both were checked outside the suite: a single array with up to 13 links, mixing watched and unwatched links, populated metadata and endedWatch, kept its order and every field except watch. Adding those cases to the fixture would only restate SQLite's JSON functions.
