SetTaskStatus was the only mutation on a task row, so a typo in a dictated
task was permanent and a deadline could not move. EditTask rewrites the three
fields capture set — text, due date and weight — and nothing else. Status
stays the one-way ladder SetTaskStatus owns.
Two things the task asked to settle.
A text edit re-normalises the dedupe key and can collide with another live
row. That is ErrTaskDuplicate, a refusal rather than a merge: two live rows
carry two provenances, two capture times and possibly two external
identities, and merging picks a winner for all three with nobody asked. The
surface names the row that holds the text.
A resolved task is refused outright (ErrTaskResolved). Its text is the record
of what was finished, and rewriting it rewrites history.
due nil clears the date, because clearing has to be sayable — an absent date
and "remove the date" cannot be one argument.
Migration #22 adds done_when and blocked_on to tasks, both NOT NULL DEFAULT
''. "He has not written one" and "there is nothing to write" are the same
state here, so no caller has to tell NULL from empty.
blocked_on is a canonical Nexus entity id, never a name. It names a person
and identity lives in Nexus, so free text here would be a second answer to a
question Nexus already owns. The caller resolves before it writes.
Both columns round-trip through ipc.TaskAPI: on ipc.Task, settable at intake
through CaptureTaskReq, and writable afterwards through the new
SetTaskFields, which is deliberately not one-way — he may sharpen a
criterion, and a blocker clears when the person answers.
SetTaskStatus now refuses candidate → open when done_when is empty
(ErrTaskNoDoneWhen, mapped across the wire), the same refusal
ParseTaskCapture makes for a capture marker with nothing after it: confirming
work whose finish line nobody wrote is how a board fills with rows that can
never leave it. Dropping such a candidate stays legal, and the /tasks confirm
button now says what is missing instead of surfacing a not-found.
One caller skips the gate. CaptureTask promoting a candidate he stated out
loud would otherwise be denied intake rather than asked for a criterion, and
a direct open capture never carried one either. The gate belongs to the
deliberate promotion on /tasks, where V-511 puts a form.
A task extracted from mail deduped on the live-norm index only, so once he
finished it the row left the live set and the next poll of the same immutable
message re-extracted it as a fresh candidate. mavmaild is a read-only reader
and marks nothing read, so that repeats forever. Derived rows now carry an
ext_id built from the message uid and the extracted span, unique across every
status, while voice keeps live-only norm dedupe because saying an errand again
is the recurrence signal. A derived source can no longer capture straight to
open, and saying a task out loud that Maven had only proposed promotes the
candidate instead of answering that it is already in the list.
SetTaskStatus was classified AuthRead. Resolving a task is not additive, it
erases work off his list, so it is a write, and the row now records the caller
that moved it. ListTasks was unbounded. The list-query matcher claimed any
utterance with "что мне делать", including "с чем мне помочь", and the urgency
stripper matched inside words.
Found in review of #60.
A task is not a fact and not a note. A fact is a claim about the world that a
correction supersedes; a note is something to recall by meaning. A task is work
with a lifecycle, and the read that matters is "everything outstanding right
now" — which over an append-only log would mean replaying history on every
question. So: a tasks table, migration #14, statuses candidate/open/done/dropped
that each move forward exactly once.
Dedupe is on normalised text among LIVE rows only, via a partial unique index.
That is the property the mail side needs: an extractor may call CaptureTask for
every message it reads, as often as it likes, without growing the list — while a
weekly errand is still capturable again once the last one is done.
Three ways in, one seam. ipc.CaptureTaskReq is it: the voice path
(router.ParseTaskCapture on an explicit marker — "добавь в задачи …", never
"надо бы поспать"), the /tasks form, and the email reader from #246 when it
exists. Mail-derived items set Source "email:<account>", Status "candidate" and
Evidence to whatever makes the row reviewable; a candidate is inert until he
confirms it on /tasks, and Maven names it as unconfirmed when she recites the
list rather than putting words in his mouth.
No new intent — the router enum is a contract with the relabelling prompt, so
capture rides the note intent and the list rides a query source, both matched
deterministically like the calendar and plan matchers already are.
Nothing here speaks. No tick rule reads tasks; the list is answered when asked
about, which is why /tasks POST is not step-up gated the way /tools and
/routines are — a task write moves no boundary.
