A shared verb is not a shared fact. 「客厅的恒温器调到 22 度」 and
「卧室的恒温器调到 24 度」 agree with each other; the store had been
recording them as one thermostat moving, and the older side then left the
answer page — asking about the living room returned the bedroom's reading
as the only evidence. A conflict now requires the two memories to lead
with the same subject, and the subject is the first content word rather
than the first word, so 「The router forwards 220 packets」 still leads
with its router behind the article.
The rule trades one error for another, and both directions are measured
and pinned: a qualifier on the subject reads as a different thing, and
the first number under a label is the value that gets compared. Neither
hides a memory — each leaves a disagreement unrecorded for a person to
supersede by hand.
Six review findings, all measured before being changed:
- the archive rule string hid that an unset importance archives too
- a never-archived id reported {"restored": 1} while nothing moved
- the suppression condition (both sides in the page) was undocumented
- a determinism claim had no reproducible path, two latency numbers were
never committed, and one cited test name did not exist
Gates: 374 passed, six acceptance files 73 passed, ruff clean, mypy cold
cache 24 errors in 9 files (the recorded 9cb46c1 baseline, net 0),
pyright 0 on the touched files, go build/vet/test + gofmt clean, npm
bundle unchanged, product audit clean, MCP smoke passing across processes.
A memory used to have one state: present. A session could not be reloaded
without searching, nothing separated what a person said today from what the
store ingested a year ago, and two statements that disagree about a number
were both handed to the reader as if the store believed both.
Schema v10. Atoms gain session_id, importance, recall_count, last_recalled_at
and archived_at; two tables arrive beside them — consolidations (one watermark
per holder+scenario lane) and conflicts (a pair, the term they disagree on,
both values, and whether anyone has settled it). v_atoms_current now also
hides archived rows, and apply() drops the view before rebuilding it because
CREATE VIEW IF NOT EXISTS would keep the old body and ignore the archive.
Working memory is a read, not a store: `working <holder> <session>` returns
what that session recorded, in order, with no search involved. Consolidation
rolls a lane's new memories into one standing summary and moves the watermark
to the newest memory actually rolled up — not to the clock of the pass, which
made a second pass count the same memories twice. The archive rule is stated
in the command that runs it (recorded before N days, never returned by a
search, importance at or under a floor) rather than hidden in a decay formula
nobody measured; --dry-run names the victims first.
A conflict is recorded when a new memory repeats a label with a different
number in the same holder's same scenario. Retrieval drops the older side
while the conflict is open and both sides answer again once it is settled:
settling is not superseding, and a word-only disagreement is left alone
because a reworded sentence would fire on every paraphrase. Numbers are keyed
to both the memory's subject and the nearest preceding label, measured: the
two thermostat sentences share only their subject, so a nearest-word-only rule
found nothing.
Search now counts the memories it handed back, which is the only use estimate
the store has, and the archive rule reads it. The dense index applies the same
currency rules as the view, so an archived memory cannot stay findable through
one leg while the other hides it.
Two reads over HTTP (working, conflicts) and two tools over MCP
(working_set, memory_conflicts); curation stays with the operator because an
agent should not decide what its own past is worth. remember and supersede
carry a session id; importance does not cross MCP, because recall_count is
observed and importance is stated.
Gates: 366 passed; ruff clean; mypy 24 errors in 9 files, the recorded 9cb46c1
baseline, net 0; pyright 0 on the touched files; go build/vet/test and gofmt
clean; mcp_write_smoke PASS.
