* feat(daemon): persistent UUID identity + legacy-id merge at register-time
daemon_id is now a stable UUID persisted to `<profile-dir>/daemon.id` on
first start, replacing the hostname-derived id that drifted whenever
`.local` appeared/disappeared, a system was renamed, or a profile
switched — each of which used to mint a fresh `agent_runtime` row and
strand agents on the old one.
To migrate existing installs without operator intervention, the daemon
reports every legacy id it may have registered under previously
(`host`, `host` with `.local` stripped, and `host[-profile]` variants
for both). At register-time the server looks up each candidate row
scoped to (workspace, provider), re-points its agents and tasks onto
the new UUID-keyed row, records which legacy id was subsumed in the
new `legacy_daemon_id` column for audit, and deletes the stale row.
Result: users running `xxx.local`-keyed runtimes today transparently
land on the new UUID row on next daemon restart.
The hostname-prefix `MigrateAgentsToRuntime` / `daemon_id LIKE '...-%'`
compatibility shim is no longer needed and has been removed along with
the handler call that invoked it.
* fix(daemon): handle bidirectional .local drift and case drift in legacy merge
Review on #1220 flagged two gaps in the legacy-id migration candidate set:
1. Reverse .local: LegacyDaemonIDs only added the stripped variant when the
current hostname ended in `.local`. The opposite direction — DB has
`foo.local`, current host is `foo` — was missed, so runtimes registered
under the `.local` variant stayed orphaned after upgrade. Now both
variants (`foo` and `foo.local`) are always emitted, regardless of what
`os.Hostname()` currently returns, plus their `-<profile>` suffix forms.
2. Case drift: os.Hostname() has been observed returning different casings
on the same machine across mDNS/reboot state. A case-sensitive `=`
comparison stranded rows like `Jiayuans-MacBook-Pro.local` when the
daemon later reported `jiayuans-macbook-pro.local`. FindLegacyRuntimeByDaemonID
now uses `LOWER(daemon_id) = LOWER(@daemon_id)` on both sides, so casing
differences merge rather than orphan. The (workspace_id, provider) prefix
still bounds the scan to a tiny set of rows so the non-indexed LOWER()
comparison has negligible cost.
Tests: TestLegacyDaemonIDs gets the mixed-case + reverse-direction cases;
daemon_test.go adds TestDaemonRegister_MergesLegacyDaemonIDRuntime_ReverseDotLocal
and TestDaemonRegister_MergesLegacyDaemonIDRuntime_CaseDrift.
* fix(daemon): consolidate every case-duplicate legacy runtime, not just the first
Follow-up review on #1220: after switching to `LOWER(daemon_id) =
LOWER(@daemon_id)`, the single-row lookup still only merged one legacy
row per candidate. If a machine already had two rows in the DB that
differed only in casing (e.g. `Jiayuans-MacBook-Pro.local` AND
`jiayuans-macbook-pro.local` coexisting because earlier hostname drift
already minted a duplicate), only one of them got consolidated and the
other stayed orphaned — violating the "no duplicate runtime per machine
after backfill" acceptance.
- FindLegacyRuntimeByDaemonID → FindLegacyRuntimesByDaemonID (:many)
- mergeLegacyRuntimes iterates every returned row and dedupes across
overlapping legacy candidates so `foo` and `foo.local` both resolving
to the same stored row don't double-process
Test: TestDaemonRegister_MergesAllCaseDuplicateLegacyRuntimes seeds two
case-duplicate rows with one agent each and confirms both rows are
deleted and both agents end up on the new UUID-keyed row.
* fix(daemon): prevent duplicate runtime registration on profile switch
The daemon_id included a profile name suffix (e.g. "hostname-staging"),
so switching profiles created a new daemon_id that bypassed the UPSERT
dedup constraint, leaving orphaned runtime records in the database.
Three changes:
- Remove profile suffix from daemon_id — use stable hostname only.
The unique constraint (workspace_id, daemon_id, provider) already
prevents collisions within the same workspace.
- Auto-migrate agents from old offline runtimes to the newly registered
runtime during DaemonRegister (same workspace/provider/owner).
- Add TTL-based GC in the runtime sweeper to delete offline runtimes
with no active agents after 7 days.
Closes MUL-695
* fix(daemon): address code review issues on PR #906
1. Move gcRuntimes() to the main sweep loop — previously it was inside
sweepStaleRuntimes() after an early return, so it only ran when new
runtimes were marked stale. Now it runs every sweep cycle independently.
2. Fix DeleteStaleOfflineRuntimes to exclude runtimes with ANY agent
reference (not just active ones). The FK agent.runtime_id is ON DELETE
RESTRICT, so archived agents also block deletion.
3. Scope MigrateAgentsToRuntime to the same machine by matching
daemon_id LIKE '<current_daemon_id>-%'. This prevents cross-machine
agent migration when the same user has multiple devices.
Previously, runtimes could never be deleted once an agent was created
because agents can only be archived (not deleted) and the count check
included archived agents. Now the check only counts active agents, and
archived agents are cleaned up before runtime deletion.
Add owner_id to agent_runtime table to track who registered each runtime.
Backend: new delete endpoint with role-based permissions (owner/admin can
delete any, members only their own), list filtering by owner (?owner=me),
and agent dependency check before deletion.
Frontend: Mine/All filter toggle in runtime list, owner display in list
items and detail view, delete button with AlertDialog confirmation.

- Coalescing queue: use HasPendingTaskForIssue (queued/dispatched only)
instead of HasActiveTaskForIssue so comments during a running task
enqueue exactly one follow-up task that picks up all new comments.
- Stale task cleanup: runtime sweeper now fails orphaned tasks when
their runtime goes offline (daemon crash/network partition).
- Cancel-aware daemon: handleTask checks task status after execution
and discards results if the task was cancelled mid-run (e.g. reassign).
- Terminal issue guard: ClaimTaskForRuntime auto-cancels pending tasks
for done/cancelled issues instead of executing them.
- Race condition safety net: unique partial index ensures at most one
pending task per issue at the DB level.
The only path to marking a runtime offline was the daemon's deregister
call on graceful shutdown. If the daemon crashed, was killed, or lost
network, the status stayed "online" forever. Add a background goroutine
that sweeps every 30s and marks runtimes offline after 45s without a
heartbeat (3 missed intervals).
