jschoubben 23232e019a ADR 0042 — the approval is the checkpoint, not the second pair of hands
§2 said "never merge your own", written for people. Applied to an agent it
produced a contradiction that surfaced immediately: an agent asked to merge
cannot merge, because it authored what it is being asked to merge. So every
merge here was either performed by the thing that wrote it, or not performed.

Rejected the literal reading, because an operator clicking merge dozens of times
without reading is not a checkpoint — it is the SHAPE of one, which is worse,
since the record then claims a review that did not happen. Rejected dropping the
rule, because the failure it prevents is not one an agent is less prone to.

So the rule names what the checkpoint actually is: a person deciding, not a
person clicking. Work may be merged by whoever wrote it once a human has
explicitly approved that merge. What "explicit" excludes is the half that can
rot, so it is enumerated: a standing permission cited forever, an instruction to
do the work read as approval to merge it, silence, and the author's own
judgement that it is ready.

This narrows rather than relaxes. The obligation moves from who performs the
merge to whether a person decided — a higher bar in the case the old wording
permits, where a reviewer merges someone else's work without reading it.

Synced, and verified by reading the rule back out of the live page rather than
by trusting the publish.

02-DECISIONS

Architecture decision records — the "why" trail behind the rules in 00-META and the specifications in 03-DESIGN.

Numbered 02 because a decision precedes the design it authorises. Research concludes, the decision is recorded here, and only then is the design written. Following the folder numbers walks the process in the order it happens.

One file per decision, numbered, never deleted. A superseded record has its status: changed and gains a pointer to what replaced it — its text is never edited. The reasoning that was rejected is the expensive half to rediscover.

The records run in the order the decisions were taken, oldest first.

Every decision is a record. There is no ledger and no index file — if a decision is worth recording it is worth a record, and if it is not worth a record it is not recorded (ADR 0026). A "decision" small enough to be one line is almost always a rule, and a rule belongs in 00-META/how-we-build.md, where it is enforced and keeps the incident that earned it.

Body

# N. Title in plain language

## Context            what was true, with evidence
## Considered Options numbered, each with why it was rejected
## Decision           what was decided
## Consequences       what follows, including what got harder
## References         commits, pull requests, knowledge-base entries, prior art

State evidence, not assertion. "Zero of 124 modules declare brain as a dependency" outranks "the dependency rule is not followed".

Reconstructed records

Records 0001–0014 were written on 2026-08-23, after the decisions they describe. Records 0015 onward were taken as records. Those decisions were taken in implementation rather than in a document; the records state what was decided and the evidence it was decided from, and each carries reconstructed: true and says so in its first lines.

A reconstructed record is not a transcript. Where the deliberation is not recoverable, the options section states what the alternatives were and why the chosen one won on the evidence available — not a discussion that did not happen. Where a date is not establishable it says so rather than guessing.

Index

The index is generated, not maintained — run the hq-status skill, which reads the frontmatter of every record. A hand-written index drifts from the folder it describes, and this one had already done so after a single addition.
