docs(memory): record the write-gate deadlock and the two stores behind it

[wenzowski]

What

One commit, one memory: mem:workflow/landing-loop gains two sections recording three traps this session paid a lap each for.

• The write gate, and the two stores that decide when it opens. plan cover partial is tree-scoped, so an in-flight plan entry reds every batten-check, so verify writes no receipt, so turn mint ahead refuses every write — with deleted via batten record plan as the gate's own free exit, reachable while the write gate holds. A red verify at HEAD with the marker set is a genuine deadlock (the fix for the red needs a write; the write needs a receipt only that fix can earn); the exit is to push, then git reset --soft to a commit that already carries a green verify.<sha>, and land the fix in that window. refusal::first_sighting keys its store under $GIT_DIR, so a fixture without its own repository shares the enclosing one's history and a cold state root controls nothing.
• A control must control the thing the code actually reads. The habit behind three wrong diagnoses, none reproduced before it was reported and one filed as an Urgent row that then needed a correction.

Why it is its own PR

diff ship early refuses a prose-only diff, correctly: a CI matrix confirms nothing about a comment. The declared route out — let the next change to these files carry it — does not apply, because a change to a memory is prose-only by construction and there is no next change to ride. The admission is spent and recorded in the commit's Admits: trailers, with the answer to each question the class asks. PR #955 is the precedent for the shape.

The row is already In Review

CLOUD-1832 was closed by #978, which landed the fix these traps were met while making. This PR records what the session learned on the way and completes nothing, so the citation is deliberately not in closing form.

📝 Walkthrough

Walkthrough

The memory adds guidance on the turn mint ahead write gate, verify receipts, terminal branch plans, and $GIT_DIR stores. It documents refusal rendering behavior and receipt invalidation during history changes. It also records incorrect diagnoses and requires reproduction controls to target the variable read by the source code.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to 3c3b6

The workflow guide can cause unnecessary resets and force-pushes for plan-related verification failures that can instead be resolved by closing the plan. Clarify this before merging.

Limit the deadlock rule to gated verification failures.

A pending or in_progress plan can make verify red while batten record plan remains reachable. Recording the plan as deleted is the documented exit because deleted is terminal. Therefore, a red verify at HEAD with unlanded-nudged set is not always a deadlock requiring git reset --soft.

Qualify the rule for cases where the plan is terminal and the verification failure requires a mediated write that the gate blocks. This prevents an unnecessary history reset and force push.
