Ticket

The delivery loop, as one skill. The human names the action:

/ticket load <ticket> /ticket start /ticket adversary /ticket review /ticket complete [<ticket>]

Process

1. Take the action from the invocation. If none was given, list the five actions below and stop. If it is not one of the five, say so, list them, and stop.
2. Read only skills/ticket/actions/<action>.md and follow it exactly.

Actions

• load — prepare one ticket for execution. Resolves the ticket store, reads the ticket and its parent Feature spec, verifies every blocker, loads the minimum context the ticket names, and writes the session's workspace state.
• start — implement the loaded ticket, restating the pre-implementation summary before editing anything.
• adversary — optionally challenge one implemented ticket through bounded, reproducible experiments. It gives no verdict, changes no lifecycle status, and hands suspected defects to Tester.
• review — verify implemented work against the ticket and its parent Feature, and report findings. It changes no implementation and accepts nothing.
• complete — complete work the human has accepted, through the project's delivery workflow and its durable records, then name the tickets that are now ready.

Lifecycle

A ticket's status holds the durable lifecycle state named in context/ai-interaction.md. It lives in the ticket store — see skills/ticket/store.md, which is where the store and ticket identity are defined:

Proposed → Ready → In Progress → Complete

Cancelled and Superseded are terminal alternatives.

• load writes Proposed → Ready.
• start writes Ready → In Progress.
• complete writes Complete.
• adversary writes no status.
• review writes no status. Review is workflow activity, not lifecycle state.

The parent Feature's status is derived from its tickets, never maintained by hand. start and complete are the only actions that write it, and each writes it only as a consequence of the ticket transition it just made.

context/current-ticket.md is transient workspace state and records no status.

Execution mode

A project records how Pathfinder runs it in context/execution-mode.md, on one marker line:

<!-- pathfinder:execution-mode <value> -->

The values are human-in-the-loop and orchestrator. No file means human-in-the-loop; every project installed before the file existed is one, and nothing needs migrating. A file whose marker is missing or names anything else is invalid: report it once, naming the file and the two values, and proceed as human-in-the-loop. Never infer a mode from prose, the environment, or the harness.

Every reader of the mode — the actions below, whereami, and the session orientation handler — reads it this way, and nothing else restates it. In human-in-the-loop mode nothing in this skill behaves differently from before the file existed.

Full-suite reuse

A role may cite a full-suite run it made earlier instead of running the suite again only when all of these hold: the same role made it, in the same session; HEAD is unchanged and git status --porcelain was empty at that run and is empty now; that run exited 0; and no dependency, lockfile, environment, or install change has happened since. The citation is one line, suite: <command> | head <sha> | clean | exit 0 | <counts> | <UTC time>. A dirty tree is never reused. These always run fresh: focused tests after an edit; any run after a change; a run by another role or in another session, which is never cited; the Tester's own run at the Developer's head; Adversary experiments; CI; complete's final checks (its step 1), whether they run pre-merge or post-merge; and any re-run after a failure.

Rules

• Run the one action the human named. Do not continue into the next one.
• Read only that action's file. The other actions are not context for this work.
• One ticket at a time. A session that finishes a ticket stops there.
• Human authority is unchanged: approval, acceptance, merge, and release are the human's, whichever action is running.
