feat(backlog): extract the execution loop into work-the-backlog.org

work-the-backlog.org now owns the autonomous execution loop: the mechanical eligibility gate, the four-item defer checklist, the per-task quality bar, and the run-cap kill switch, fed a task set, session mode, and cap by its callers. I stubbed the pre-flight Q&A, waiver read, end-of-set page, and metrics record with pointers to their phases.

inbox.org's auto mode drops its execute step. Per-cycle item 3 routes and queues only, so the loop has one home. This is Phase 1 of the autonomous-batch execution spec.

 *** 2026-07-02 Thu @ 00:44:59 -0400 spec-response decomposition — :SPEC_ID: bound, spec DOING
 Stamped the spec's UUID on this parent, broke Phases 1-6 into the build tasks below (plus the flip task and a live-trial validation child), and flipped the spec's status heading READY → DOING per the transition-ownership table.
 
-*** TODO [#C] Phase 1 — extract the loop into work-the-backlog.org :feature:solo:
-Write work-the-backlog.org holding the eligibility gate (mechanical tag read: :solo: present, no do-not-auto-implement marker), the defer checklist, the per-task quality bar (TDD red→green, /review-code, /voice on the commit), and run-cap logic — inputs: task set + session mode + cap. In the same change, revert inbox.org's "auto inbox zero" execute step (per-cycle item 3's "Yes → launch into implementing...") to routing-only so the execution loop has one home. Spec Phase 1. Verify: make test green, sync clean; the new workflow is callable but nothing invokes it yet.
+*** 2026-07-02 Thu @ 01:07:29 -0400 Phase 1 landed — execution loop extracted into work-the-backlog.org
+work-the-backlog.org written (canonical + mirror): caller contract (task set + session mode + cap), five-outcome vocabulary, the loop, mechanical eligibility gate (TODO + :solo: per scheme header, safe-by-omission, no-scheme-header → don't run), four-item defer checklist, per-task quality bar, cap/kill-switch semantics, page + metrics stubs pointing at Phases 4-5. inbox.org's auto-mode per-cycle item 3 reverted to routing-only (yes-path execution removed; mode intro + closing line updated to match). INDEX.org entry added. make test green, sync clean; nothing invokes the new workflow yet.
 
 *** TODO [#C] Phase 2 — wire the two callers :feature:solo:
 Auto-inbox-zero's "run this batch next?" yes-path invokes work-the-backlog (tag query + file-only + cap 1); the no-approvals speedrun preset (trigger phrases "speedrun" / "no approvals speedrun") feeds it an explicit ordered list + autonomous-commit + always-push + paging-on, running the pre-flight Q&A first. Spec Phase 2 / D4 / D7. Verify: each caller independently exercisable.
