Tasks: the checklist asks, the config answers when nobody did

Phase 3 of 3. A DAG of small, verifiable tasks. Each task references the requirements it serves and names the testing-plan row that proves it. tdd.mode: standard — the red tests come first and their failure is captured as evidence.

Task list

• [x] T1 — red: the gate renders and freezes a mode. Assert the posted checklist carries the three pr-sessions-* rows with the configured default pre-ticked; that ticking one freezes it into the decision, the frozen graph and the published record and names it in the confirmation; that none/several fall back to the default; and that a mode row is never read as a phase. Fails today: no such rows. Requirements: R1.1–R1.5, R3.1, R3.3 · Test: T1, T10
• [x] T2 — red: routing honours the frozen mode. Assert _endpoint_for under a frozen always / never / absent / invalid mode on a daemon configured cross-repository, that two work items resolve independently, and that delivery_status resolves through the same mode. Fails today: only self.config.tmux is consulted. Requirements: R2.1–R2.5, R3.4 · Test: T3, T10, T12
• [x] T3 — red: the integration scenario. One Gherkin-documented scenario through the receiver: a work item frozen to never on a daemon configured cross-repository keeps a cross-repository pull request's events in the work item's session. Requirements: R1.2, R2.1 · Test: T4
• [x] T4 — green: the shared vocabulary. Move the mode constants and the resolver out of webhook/dispatcher.py into the_loop/prsessions.py; the dispatcher imports them. No behaviour change — T2 of the testing plan proves the resolver from its new home. Requirements: R3.2 · Test: T2
• [x] T5 — green: the operator's default reaches the gate. graph/bootstrap.py reads routing.tmux.sessionPerPr from the CLI config it already loads and puts the resolved mode in the hook config. Requirements: R1.1, R3.2 · Test: T1 · Depends: T4
• [x] T6 — green: the rows. graph/hooks/selection.py renders the three rows, parses them into a mode, keeps them out of the phase vocabulary, states the result in the confirmation, and carries it on the hook result and inside frozenGraph. Turns T1 green. Requirements: R1.1–R1.4, R3.1, R3.3 · Test: T1, T10 · Depends: T5
• [x] T7 — green: recording. graph/runtime.py copies the mode into the phase-selection decision beside surface; ControlStore gains the reader that mirrors record_frozen_graph. Requirements: R1.3 · Test: T1, T3 · Depends: T6
• [x] T8 — green: routing. Dispatcher._tmux_for(work_item) substitutes the frozen mode into the operator's TmuxConfig; _endpoint_for and delivery_status use it. Turns T2 and T3 green. Requirements: R2.1–R2.5, R4.1–R4.3 · Test: T3, T4 · Depends: T7
• [x] T9 — docs: the configuration reference. docs/config/cli/routing-options.md states that tmux.sessionPerPr is the default and that phase-selection overrides it, with the token names. Keeps the docs-parity gate green. Requirements: R1, R2, R3 · Test: T14 · Depends: T8
• [x] T10 — docs: capabilities, skill and decision.docs/capabilities/process-graph.md (the gate's second and third questions), docs/capabilities/webhook-triggers.md (routing reads the frozen mode first), docs/cli/state.md (the portable record's new key), the two cli-config.yaml commentaries and both schema descriptions, skills/the-loop/reference/workflow.md + skills/the-loop/SKILL.md (the checklist's other box), and decision-093.md + the decisions index. Requirements: R1, R2 · Test: T14 · Depends: T8
• [x] T11 — verification. Run every activity in testing-plan.md, commit the evidence, fill Verification results. Test: all · Depends: T9, T10

Dependency graph (DAG)

The three red roots are independent: the gate (T1), routing (T2) and the end-to-end scenario (T3) each fail for their own reason before any production line moves.

Checkpoints

• After T3: the full red run is captured to evidence/red.md and committed before any production line changes. That commit is the TDD record.
• After T8: make test is green — proof that R3 holds (the default path is untouched) before any documentation is written against the new behaviour.
• After T11: the ready-to-ship gate — green checks, capability docs updated in this pull request, reviewer briefing posted.
