fix: schedule periodic snapshot timer (#1006)#1039
Conversation
SNAPSHOT_ENABLED and SNAPSHOT_INTERVAL were read and logged but never passed to setInterval. The snapshot function was registered but only fired on manual trigger (MCP tool or POST /snapshot/create). Add setInterval(sdk.trigger(mem::snapshot-create), interval * 1000) with .unref() matching the pattern used by auto-forget, lesson-decay, insight-decay, and consolidation timers.

📝 WalkthroughWalkthroughThe snapshot feature in src/index.ts now schedules a setInterval that periodically triggers mem::snapshot-create using the configured interval, unrefs the timer, and suppresses trigger errors. A new test file verifies the interval computation and timer creation/unref behavior. ChangesSnapshot Interval Scheduling

In `@test/snapshot-interval-timer.test.ts`:
- Around line 11-36: The snapshot interval test is mocking the entire config
module, so the assertion only checks the stubbed loadSnapshotConfig return value
instead of the real parser. Update the setup in snapshot-interval-timer.test.ts
to keep the real loadSnapshotConfig behavior for the value check while still
mocking only the other helper functions from ../src/config.js, and adjust the
assertion around the interval validation to exercise the actual config parsing
path.
- Around line 61-82: The snapshot timer test is only validating generic timer
math and never exercises the real snapshot scheduler path. Update the test to
import and run the bootstrap/helper logic in src/index.ts (or the relevant
snapshot setup function) with iii-sdk mocked using the repo’s existing test
pattern, then assert setIntervalCalls and sdk.trigger are invoked with
mem::snapshot-create when snapshotting is enabled. This should fail if the
production timer is removed, not registered, or targets the wrong function.

Don't mock the config module for the value check.
vi.mock("../src/config.js") replaces loadSnapshotConfig, so the assertion at Lines 55-59 only verifies the stubbed return value. That can't catch regressions in the real parser. If you only need the other config helpers mocked, keep the real loadSnapshotConfig for this case.
Also applies to: 55-59

This test never exercises the snapshot scheduler.
It doesn't import src/index.ts, it never checks setIntervalCalls, and it never observes sdk.trigger, so it will still pass if the production timer is removed or pointed at the wrong function. Please drive the actual bootstrap/helper path with iii-sdk mocked per the repo test pattern.

Problem
SNAPSHOT_ENABLED=trueandSNAPSHOT_INTERVAL=3600were correctly loaded vialoadSnapshotConfig()and displayed in the boot log, but no periodic timer ever calledmem::snapshot-create. The snapshot function was registered, but unlike auto-forget, lesson-decay, insight-decay, consolidation, and recent-searches-sweep — which all havesetIntervalblocks — snapshots had no corresponding timer.Snapshots were only created on manual trigger (MCP
memory_snapshot_createtool orPOST /agentmemory/snapshot/create). If the daemon crashed between manual snapshots, all data since the last snapshot was lost.Fix
Add
setIntervalfor snapshot creation insrc/index.ts, matching the exact pattern used by the other periodic tasks:The timer is
.unref()-ed like all other periodic timers so it doesn't keep the process alive.Test
test/snapshot-interval-timer.test.tsverifies:loadSnapshotConfig()returns the expected interval valueCloses #1006
