About this skill

Dispatch — codex/pi arm

Spawn a worker via doctrine worktree fork --worker + subprocess spawn. Drive loop lives in the /dispatch router.

Spawn — codex arm

doctrine worktree fork --base "$B" --branch "$BR" --dir "$D" --worker \
  || { echo "fork failed: $?" >&2; exit 1; }
env -C "$D" DOCTRINE_WORKER=1 codex exec "<pre-distilled prompt>"

Confined (bwrap); run the fork, check $?, then spawn. The worker inherits the ambient env and compiles into its own in-tree $D/target (no env contract).

Spawn — pi arm (RPC mode)

doctrine worktree fork --base "$B" --branch "$BR" --dir "$D" --worker \
  || { echo "fork failed: $?" >&2; exit 1; }
cp AGENTS.md "$D/" \
  || { echo "AGENTS.md copy failed: $?" >&2; exit 1; }
PI_FIFO=$(mktemp -u) && mkfifo "$PI_FIFO"
{ printf '%s\n' \
    '{"type":"set_auto_retry","enabled":false}' \
    '{"type":"prompt","message":"<pre-distilled prompt>"}'
  sleep 300
} > "$PI_FIFO" &
timeout 300 env -C "$D" DOCTRINE_WORKER=1 \
  pi --mode rpc --thinking off --session-dir "$D/.pi-session" \
     --no-extensions --no-skills --no-themes \
     --offline --approve --tools read,bash,edit,write,grep,find,ls \
  < "$PI_FIFO"
rm -f "$PI_FIFO"

Same confinement as codex arm; fifo keeps stdin open (pi RPC exits on EOF). sleep 300 keepalive, agent_end gives typed completion. Ignore extension_ui_request widget events from installed packages.

Boundary recording

At the conclude prescription (doctrine dispatch next --slice <N>), after the code commit: doctrine slice record-delta <SL> PHASE-NN --commit <S> — the safe-default single-commit mode. It derives [S^, S] and writes the per-phase boundary into the primary-tree conformance registry (F-5 resolves it from the coord tree; F-6 guard; upsert).

Pin S at the code commit; never read HEAD at record time. Knowledge commits trail the code commit, so by the time you record, HEAD may no longer be the code commit. Capture S=$(git rev-parse HEAD) immediately after the code commit lands and record --commit "$S" before trailing knowledge (or with the pinned oid regardless of order). git diff S^..S is exactly S's own patch — trailed knowledge and any refresh-base merge (which sits in S^) are excluded by construction; this is what the old --start/--end range failed to do.

This arm has no record-boundary and the codex/pi symmetric ledger derive is deferred (D6/IMP-171), so this record-delta is the arm's registry write — RETAINED, every landed phase, orchestrator-issued. It is no longer skippable: dispatch sync --prepare-review's completeness gate bail!s if a completed phase lacks a registry row, so a forgotten write halts the pre-audit conclude beat instead of silently passing (the ISS-052 failure mode). The same verb still doubles as the manual escape hatch — --start/--end remains for a range / bootstrap. Its incoming Manual is provenance-preserving — it never clears an existing funnel/legacy halt (D12).

Red Flags

Never: eval; spawn outside env -C "$D"; omit timeout; use a heredoc for RPC mode (stdin EOF kills pi); hand-sequence the funnel from memory (ask doctrine dispatch next --slice <N>). Always: halt on fork failure; carry DOCTRINE_WORKER=1; use a fifo for RPC stdin; rm -f the fifo after exit; return to the router for the funnel cadence.
