docs(slice1): schema v3b, current snapshot view (darkwing)
Lead decision 59. task_current picks each task's current snapshot, skipping a poll row whose read_at is at or before the latest self row's at; tasks_open reads it. Prototype on Node 24 and 26, two mutants caught, and Dewey's fixture replayed: tasks_open now differs from v3a only on #42 (in-progress). The notes add an S3 poller rule: compare a read against task_current, not the raw latest row. Co-Authored-By: Claude Opus 5.5 <[email protected]>

# Slice 1 prototype, v3b (lead decision 59)
|
||||||
|
|
||||||
|
Darkwing, 2026-10-04. Dewey's mockup check found the case, recorded in
|
||||||
|
`agents/dewey/work/wui/SLICE1-VIEWS.md` section 8. A board read that
|
||||||
|
started before the broker's own move is written, because its digest
|
||||||
|
differs from the latest row. It then becomes the latest snapshot, and
|
||||||
|
`tasks_open` shows the old bucket until the next tick. Sage's ruling keeps
|
||||||
|
the row as evidence and puts the rule for "current" in the schema.
|
||||||
|
|
||||||
|
`schema-v3b.sql` is a full schema that replaces v3a. It isn't a
|
||||||
|
migration, and the v1 to v3a files are unchanged. `diff schema-v3a.sql
|
||||||
|
schema-v3b.sql` shows the whole change:
|
||||||
|
- New view `task_current`: one row per task, with every
|
||||||
|
`task_snapshots` column. It is the task's highest-`seq` row, skipping a
|
||||||
|
`poll` row whose `read_at` is at or before the `at` of the task's latest
|
||||||
|
`self` row. A task with no `self` row takes its latest row.
|
||||||
|
- `tasks_open` now reads `task_current` instead of picking the latest row
|
||||||
|
itself. Its columns are unchanged.
|
||||||
|
- `task_external_changes` is unchanged. It already ignores a read with
|
||||||
|
`read_at` at or before the latest `self` row, and it only reports a
|
||||||
|
task whose latest row is a poll, so a row it reports is also that
|
||||||
|
task's current row.
|
||||||
|
|
||||||
|
Counts: tables 8, triggers 36 (the prototype prints 35 after its tamper
|
||||||
|
check drops one), views 5. Schema digest (the `meta` value the
|
||||||
|
prototype stores at create time):
|
||||||
|
`52514a1173bef256ac262b397321bd5cf16f6a903ea2de40e25db895154fc692`.
|
||||||
|
|
||||||
|
## A rule for the S3 poller
|
||||||
|
|
||||||
|
Today the poller writes a poll snapshot when the read's digest differs
|
||||||
|
from the task's latest row. It has to compare against `task_current`
|
||||||
|
instead. Otherwise a stale row can hide a real change. In this sequence:
|
||||||
|
1. The broker moves a task to `in-progress`.
|
||||||
|
2. A stale read still shows `todo` and is written.
|
||||||
|
3. A person really moves the task back to `todo`.
|
||||||
|
|
||||||
|
The next read shows `todo`, which matches the stale latest row, so the
|
||||||
|
poller doesn't write it. The view goes on showing `in-progress`, and
|
||||||
|
`task_external_changes` never reports the person's move. Compared against
|
||||||
|
`task_current`, the read differs and is written, and both views come out
|
||||||
|
right. The prototype shows both comparisons on `vikunja:3/46`. This is my
|
||||||
|
row (S3), and it applies to addendum B section 5. It isn't a reason to
|
||||||
|
skip the stale write; with the comparison fixed, keeping the row costs
|
||||||
|
nothing.
|
||||||
|
|
||||||
|
## Prototype
|
||||||
|
|
||||||
|
`proto-v3b.mjs` is `proto-v3a.mjs` with these changes:
|
||||||
|
- the header, the temp directory prefix and the schema file name;
|
||||||
|
- a `digest` line after the open-time check;
|
||||||
|
- `task_current` and `tasks_open` shown for `vikunja:3/41` right after the
|
||||||
|
stale board read;
|
||||||
|
- a new section, "current snapshot", with a read whose `read_at` equals
|
||||||
|
the `self` row's `at` (skipped), the two poller comparisons, the
|
||||||
|
person's move (now current and external), and a check that
|
||||||
|
`task_current` has one row per task.
|
||||||
|
|
||||||
|
Results: `proto-v3b-node24.txt` (Node 24.21.0 in the `node:24` image, no
|
||||||
|
network, the directory mounted read-only) and `proto-v3b-node26.txt`
|
||||||
|
(Node 26.8.1 on the host). Both use SQLite 3.53.4, and the outputs differ
|
||||||
|
only in the version line. Against `proto-v3a-node26.txt`, every v3a line
|
||||||
|
is unchanged. The new lines are the digest, the two views after the stale
|
||||||
|
read (bucket 13, in review, not the stale read's 12, in progress), the new
|
||||||
|
section and the view count of 5.
|
||||||
|
|
||||||
|
Mutants, each run with the same script in `~/darkwing-scratch/v3b`:
|
||||||
|
- The rule dropped (`task_current` is the plain latest row): the stale
|
||||||
|
read shows as current on `vikunja:3/41` (bucket 12) and on
|
||||||
|
`vikunja:3/46`, and the current-based poller comparison says "no
|
||||||
|
write". Caught on four lines.
|
||||||
|
- `>` widened to `>=` (a read at the same instant as the `self` row
|
||||||
|
counts): `vikunja:3/46` shows the stale read. Caught on two lines.
|
||||||
|
|
||||||
|
## Dewey's fixture
|
||||||
|
|
||||||
|
`fixture-replay.mjs` loads `mockups/slice1/data.js` (sha256
|
||||||
|
`aed3616f…`, Dewey's uncommitted working file, read-only) the way
|
||||||
|
`checks/slice1-verify.mjs` check 15 does, without the browser, into both
|
||||||
|
schemas. All 72 rows insert in both. `tasks_open` differs only on #42:
|
||||||
|
`todo` in v3a, `in-progress` in v3b. `task_external_changes` and
|
||||||
|
`urgent_inbox` are the same in both. Check 15 found v3a differed from the
|
||||||
|
page on #42 alone, so v3b agrees with the page on every row. Output:
|
||||||
|
`fixture-replay.txt`. Dewey's check still pins `schema-v3a.sql` d55e41fd;
|
||||||
|
moving it to v3b is Dewey's change.
