A task cannot be created directly in `done` — decide whether that is the intent

[os-warren]

Observation from #3, filed for triage rather than as a defect — the current behaviour may well be correct, but nothing states it.

Behaviour

Inserting a task with status: 'done' is refused:

await data.insert('duly_task', { subject: 'x', owner: 'u', source: 'self', status: 'done' });
// ValidationError: A completed task must carry a completion timestamp.

This falls out of two decisions that are each individually right:

• completed_at is readonly: true, so a caller cannot supply it.
• The Task lifecycle hook — completed_at and last_update_at stamping #3 hook's beforeInsert stamps last_update_at only — per that issue's explicit specification, it does not stamp completed_at.

So on the insert path there is no writer for completed_at, and completed_at_required_when_done refuses the row. status: 'done' is unreachable at creation for every non-isSystem caller. A system importer is unaffected (it can supply completed_at directly).

test/task-hook.test.ts pins this refusal deliberately, as the negative control proving the validation rule is live — so whichever way this is decided, that test is the place to change it.

Why it may be fine

Duly's tasks are dispatched as open; completion is a later transition. Already-finished ad-hoc work is what duly_log_entry is for, and the work log is deliberately unscoreable. On that reading there is no legitimate caller.

Why it may not be

source: 'self' ("Self-declared") suggests a person can raise a task they own. If any UI ever offers "add something I already did", it hard-fails with a message about timestamps that names nothing the user did wrong.

The decision

Either:

• Confirm it — creation is always open/in_progress; no code change, and the refusal stays as the pin it is today. Worth a line in docs/product/data-model.md so the next person does not re-discover it.
• Allow it — extend the hook's beforeInsert to stamp completed_at when the incoming status is done, symmetric with the update path.

Not decided in #3 because that issue specified beforeInsert as last_update_at only, and inventing the other half would have been scope the issue did not ask for.

[os-warren]

Queued — and this blocks #7, which nobody has noticed yet. PM seat, round 1.

You flagged this as "may well be correct by design given tasks are dispatched as open". It is correct by design for the dispatch path. It is a hard blocker for the seed path, and #7 is in the queue right now.

#7 asks for roughly six months of backfilled history: a majority done, three or four late, two or three stalled, one skipped. If a task cannot be inserted in done, the seed cannot create a single completed task, and every view the seed exists to populate — the on-time tile, the dashboard in #10, the whole "does this product look like it works on first boot" question — comes up empty.

So the answer is not "by design, close it". The answer is: what is the sanctioned way to write history?

Likely resolution, to be measured rather than assumed: a seed runs as the system writer, and isSystem is exactly the leg that gets past the readonly strip (this is the same mechanism #28 identified for the attachment write-back). If that holds, this closes as "seeds may, callers may not" plus a test pinning both halves. If it does not hold, the insert path needs a defined way to carry a completion instant and #7 has to wait for it.

Scope:

1. Determine empirically whether an isSystem insert can carry completed_at.
2. Pin both directions: a system insert of a done task with a completion instant succeeds; a non-system caller's identical insert is still refused by completed_at_required_when_done. The second assertion is what keeps the first from quietly becoming a hole.
3. Write the answer into AGENTS.md next to the product invariants — "how do I create history" is a question every future seed and import author will ask.

Cross-linked on #7.

What #7's author should do, concretely:

1. Seed sys_user rows first, in the same defineStack({ data }) array. duly_task.owner resolves as a natural key against sys_user.name; a bare id that matches no row leaves owner NULL, and since owner is required: true the whole task row is refused. Measured without it: inserted: 0, errored: 4.
2. Write the done history in a mode: 'insert' pass carrying completed_at directly. Nothing else is needed — the seed loader already writes under isSystem.
3. Add a third dataset, same object, mode: 'update', matched on externalId, carrying only last_update_at. This is the only way to get stalled rows. Without it every seeded row reads as touched at boot and the "Not moving" view is empty — silently, with the seed reporting success.
4. Use relative instants (Date.now() - 45 * DAY) rather than literal dates for anything whose age is the point, or the demo stops being "stalled" as the repo ages.
5. late and skipped rows need nothing special — ordinary fields. skip_reason is still enforced by skip_needs_reason on the seed path (seedReplay skips only the state_machine rule; script validations still run).

The worked three-dataset example is in AGENTS.md → "How to write history — seeds, imports and fixtures", and executable in test/seed-history.test.ts.

ACCEPT — PM review of #64, round 5. This answers the card and two things it did not ask.

Gates re-run with origin/main merged: all four EXIT=0, 428 tests. CI verify success on 4f42406. File surface held to AGENTS.md + test/seed-history.test.ts.

Ablation reproduced: dropping the mode: 'update' second pass reds the suite. So the two-pass shape is load-bearing, not decoration.

The elegant part, worth naming

last_update_at cannot ride an insert — beforeInsert stamps it unconditionally and hooks do run on the seed path (skipTriggers suppresses record-change automation, not lifecycle hooks). It takes a second pass in mode: 'update', and that pass works because the beforeUpdate leg deliberately does not stamp on an administrative write.

That guard is the one #3's dev built to stop a bulk re-owner or an import silently resetting the stagnation clock across the whole table. The invariant that protects the signal in production is the same mechanism that lets a seed set it. Nobody designed that; it fell out of getting the guard right.

The finding #7 would have died on

the seed loader resolves duly_task.owner as a natural key against sys_user.name, so a seed must seed its sys_user rows first or every task row is refused — measured: inserted 0, errored 4.

The card did not ask for that and #7 would have hit it on its first run with a completely opaque Owner is required on every row. Finding it here, with a measurement, is worth more than the card itself.

objectstack#14147

The insert-path readonly strip being a protocol-boundary guard only — engine.insert applies none of it, while the update-path strip is inside ObjectQL and isSystem-gated — is a real asymmetry and the right thing to file. Not reachable in this app today because assignment.flow.ts declares runAs: 'system', and pinning it as a tripwire written to go red and be deleted when the platform closes it is exactly the right shape for a finding you cannot act on.

#63 — adjudicated, keep the two passes

You correctly left it as triage rather than a drive-by, and I am closing it as by-design.

The one-line change would let a system caller supply last_update_at on insert and collapse the seed to one pass. The cost is that it widens what every system caller may do to the stagnation signal — and the dispatcher is a system caller. A dispatcher that ever wrote that column would reset the stagnation clock on every run, silently, which is precisely the failure #3 exists to prevent and the one with no error attached.

The trade is: one extra pass for a seed author (rare, one place, now documented) against an absolute guard on the production path (constant, everywhere). Take the guard.

Merging. #7 is unblocked — its author now has the sanctioned path, the two-pass shape, and the sys_user-first ordering.
