The proposal described one kind of record — a decision — while the store now has three. Adds §4.5 with amendments A10 and A11.

One property, not three arguments

What separates the kinds is what a failed anchor means:

Kind Anchor points Not resolving means Checked
decision backward, at what exists stale fails
requirement forward, at what is intended not built yet counted, never fails
open question at what is under discussion nothing — the question is often whether it should exist not at all

Identical syntax; only the direction differs, and that is the whole lifecycle.

Records that this was measured before it was designed: as an ordinary entry, a single not-yet-built requirement takes brain check to exit 1, and so does a question. Neither could be more decisions without making the check useless.

Where this departs from the playbook, and where it was behind

Both stated, because the difference is the interesting part.

Departs: the AI-native SDLC playbook keeps a plan.md and recommends a hook enforcing that the merged diff still matches it. That is a self-reported artifact being policed, and it is only necessary when there is no queryable model. There is one here, so progress is derived instead.

Behind: the playbook's trigger for CLAUDE.md — "when Claude makes a mistake twice, the correction goes into CLAUDE.md" — is the one thing this design was missing outright. It is now A11.

The defect the comparison exposed

The proposal asserted project.md was loaded every session and justified the store's tightest cap on that basis, with nothing behind it: a generated project mentioned the brain exactly once, in a skills-table row, behind a symptom-triggered description.

§4.5 records the general lesson rather than just the fix: a policy about what is loaded is worth nothing without the thing that loads it, and the same question should be asked of any future claim of that shape here.

Docs only. Independent of the two code branches — no shared files, so any merge order works.

…es them

The proposal described one kind of record, a decision, while the store has
three. Adds §4.5 with amendments A10 and A11.

The separating property is not three separate arguments but one: what a FAILED
anchor means. A decision's anchor points backward at what exists, so one that
stops resolving means the decision is stale. A requirement's points forward, so
one that does not resolve means not built yet. A question's points at what is
under discussion, so it means nothing at all — the question is often whether the
thing should exist. Identical syntax; only the direction differs, and that is
the whole lifecycle.

Records that this was measured before it was designed: as an ordinary entry, a
single not-yet-built requirement takes `brain check` to exit 1, and so does a
question. Neither could be more decisions without making the check useless.

Also records where this departs from the AI-native SDLC playbook and where it
was behind it. Departs: the playbook keeps a plan.md and recommends a hook
enforcing that the diff still matches it — a self-reported artifact being
policed, which is only necessary when there is no queryable model. Behind: the
playbook's trigger for CLAUDE.md ("when Claude makes a mistake twice, the
correction goes into CLAUDE.md") is the one thing this design was missing
outright, and is now A11.

And notes the defect the comparison exposed, because the lesson generalises: the
proposal asserted project.md was loaded every session and justified the store's
tightest cap on that basis, with nothing behind it — a generated project
mentioned the brain once, in a skills-table row, behind a symptom-triggered
description. A policy about what is loaded is worth nothing without the thing
that loads it, and the same question should be asked of any future claim of that
shape here.
