Why: 11 merged branches had left their task cards open (bookkeeping debt found on 2026-09-30); closure was manual and never triggered, so card status rotted after each merge.
Evidence: dogfood run of `task.sh close --fold` closed and archived the 11 cards (previous commit); temp-repo matrix 33/33 PASS covering detection, pending-branch idempotence, dirty/no-fold refusals, post-merge auto-close on merge-type pulls, worktree guard, and the full lifecycle (closure PR merge archives cards on main).
Impact: scripts/task.sh (+close, precheck [cards] report, finish-tail trigger), scripts/hooks/post-merge (new), Makefile (+task-close target, setup chmod), AGENTS.md rule; archive fixes correct PR links missed by the first dogfood run; no module or gitlink change.

Why: Provider repos merged for T1 (core PR#2, agent-command PR#2, frontend
PR#3, ui PR#3, documents PR#9); gitlinks pinned to those mains. The
task-finish guard prevents a repeat of the T0 incident where running
finish from the main checkout deleted it (scripts/task.sh treated $PWD as
the worktree to remove).
Evidence: make test green on the pinned combo — core, backend 13 pkgs,
frontend 9, ui 6, agent-command (vet + tests incl. conformance); make build
produces the binary; combo version string now includes agentcmd SHA.
Impact: combo grows its version traceability; AGENTS.md documents the
worktree-cwd requirement for finish.

Why: PR test evidence depended on the agent's word (single point); the
running binary could not answer what combination it was built from; and
irreversible operations lacked an explicit agent-stops-here boundary.
Evidence: Gitea runner online (home-runner, ubuntu-latest+docker); make
version prints describe+component SHAs; two-key line maps to baseline hard
boundary 1. CI first run observed on this PR before merge (see Actions tab).
Impact: .gitea/workflows/ci.yaml runs make test + make build on PR/push;
Makefile injects main.version (make version / agent-system version);
AGENTS.md and adoption register the two-key rule. No product code change.

Why: agents skipped triggered reading and wrote into shared checkouts holding
other tasks' in-flight changes; the 2026-09-30 empty-list incident session
found 24 overlapping in-flight files only by accident at first write.
Evidence: positive/negative suite in a real scratch repo passed 19/19
(precheck READY/BUSY/SYNC_REQUIRED, start refuse/establish, hook main/badname/
longsubject refusals, sync checkpoint, finish recycle and abandon double-
confirm); the suite caught three real defects (pipefail empty-grep abort,
worktree gitdir COMMIT_EDITMSG resolution, message checks in the wrong hook
phase).
Impact: make setup enables pre-commit/commit-msg hooks; make precheck/task-
start/task-sync/task-finish provide the governed path; no existing workflow
removed. AGENTS.md carries the resident gate rules.
