The agent's working memory survives across stateless + invocations. +3. **Cache survives pod death** — the prompt prefix cache is server-side + (Anthropic/LiteLLM), keyed on the stable prefix, not pinned to a pod. + Invocations are already one-shot, so inter-call gaps are set by event + arrival, not pod lifecycle; spawn latency adds tens of seconds to gaps that + are already minutes long. (Anthropic default cache TTL is 5 min; no + extended-TTL `cache_control` exists in the repo — true today, unchanged by + this issue.) +4. **Worktree persistence** — worktrees are hostPath-persistent across pod + restarts and keyed per `{pipeline_id}[-{slice_id}]-{role}` (#3005, #2403). + Re-attach across successive spawns is a reuse problem, not research. + +### State inventory: what a pod holds vs. what is already durable + +Lost on pod exit: container process memory, the background heartbeat +subprocess, the gateway session token, uncommitted worktree staging state. +Already durable: brc-memory.md, `.egg-state/` committed artifacts, the +worktree on disk, the message store (PROPOSE/ACK/NACK replay source), and the +consensus tracker (rebuilt from messages, #2761). The only *correctness*- +relevant pod-held state is the gateway session and any uncommitted worktree +state — both manageable at spawn boundaries. + +## Hard Constraint (learned from #3023, the scrapped first attempt) + +**The passive-wrapper coexistence guard and the on-demand spawner must land +together, or spawner strictly first.** The first run committed the +`EGG_EVENT_LOOP_OWNER` guard alone and had to revert: silencing the in-pod +loop with nothing replacing it deadlocks BRC. And since #2908 slice-4 deleted +the legacy `EGG_BRC_EVENT_PUMP` flag, the current wrapper has **no rollback +path** — the new ownership flag must default to the in-pod loop and flip only +after the spawner is proven against a live BRC cycle. + +The #3023 run's failure modes are fixed on main: contract-verify skipping +slice PRs (#3040 → #3048), post-BRC reviewer-confirm deadlock (#3043 → +#3050), overlapping-but-unordered slices rejected at plan ingestion (#3046 → +#3049). Nothing from #3023 is on main; its leftover remote branches +(`egg/issue-3023/*`, `egg/recovered/issue-3023/*`) don't collide with this +pipeline's namespace. + +## Design Questions the Plan Must Answer (grounded in code) + +1. **Spawn trigger & idempotency.** The orchestrator's consensus poll will + re-derive the same actionable event for the ~10-30s of pod startup. The + spawner needs a dedupe key: role + event identity (e.g. the + `proposal_commit_sha` already carried in `pending_reviews` payloads, + `routes/consensus.py:220-221`; for producers, the NACK version being + addressed). One event → one pod. +2. **Verb→pod mapping.** Only `propose|ack|nack` need judgment and hence a + pod. `confirm`/`complete` bookkeeping moves orchestrator-side (the wrapper + already does these agent-free). A naive mapping spawns pods that do + nothing. +3. **Failure supervision re-homing.** Today the still-running loop retries + naturally (streak backoff, #3138) and #2806's exit-code path signals + persistent producer failure. With one-shot pods, a pod dying mid-event + leaves nothing running — the orchestrator must notice (Job status) and + respawn bounded or alert. See HITL cq-2. +4. **Orchestrator-restart durability.** In-pod loops let BRC progress survive + an orchestrator bounce for free. Once the orchestrator owns the loop, the + spawn bookkeeping must either be persisted or — better — **stateless: re-derived + from consensus state on startup** (the tracker is already rebuilt from the + message store, #2761), with the dedupe key making re-derived spawns + idempotent. Cf. #3070. +5. **Worktree & session reuse.** Per-event pods make worktree setup a hot + path. Worktrees already persist; the spawner re-attaching instead of + recreating cuts spawn latency and gateway fetch traffic, but needs a + staleness/ownership story. Gateway sessions: today one per pod lifetime; + per-event pods imply setup/teardown per spawn unless sessions are reusable + per role (the spawner already pre-registers a session per Job). +6. **Health-monitor semantics shift.** `HealthMonitor` + (`orchestrator/health_monitor.py:106-400`) keys tripwires on heartbeat + timeouts (120s default, 600s implement) and container exits — both assume + long-lived pods. "Role X has no pod" becomes the *normal* state; the + idle-budget overseer alert ("role X stuck in wait N min") moves + orchestrator-side where the global judgment belongs. The + `HeartbeatCoordinator` (heartbeat.py:45-211) session-refresh side effect + (#2076, #2451) also loses its sender when no pod is running. + +## Scope Options (HITL cq-1) + +- **Option A — spawner + guard, flag off:** orchestrator-side event loop and + on-demand spawner for `propose|ack|nack`; confirm/complete bookkeeping + orchestrator-side; `EGG_EVENT_LOOP_OWNER`-style flag defaulting to the + in-pod loop; spawn dedupe + bounded respawn supervision. The in-pod path + remains the production default. Smallest honest unit that respects the hard + constraint. +- **Option B — A + lifecycle re-homing (recommended):** A plus worktree + re-attach and session reuse across a role's successive spawns, idle-budget + /stall alerts re-homed orchestrator-side, health-monitor thresholds made + lifecycle-aware, and #2806 failure signaling relocated. Delivers the full + mechanism behind the flag; the flip itself stays a follow-up gated on a + live BRC cycle run with the flag on (the issue's own bar). +- **Option C — B + default flip and in-pod loop retirement:** also flips the + default to orchestrator-owned and deletes the in-pod wait arm in this same + pipeline. Violates the spirit of the proven-first bar unless the pipeline + itself can run a live BRC validation cycle before the flip commit. + +Recommendation: **B**. The first attempt died by descoping the spawner itself; +A is defensible but leaves operational re-homing (supervision, monitors) as +debt that makes the flip risky later. C front-loads the flip without the +proving run the issue demands. + +## Risks / Trade-offs + +- **Deadlock by partial landing** — mitigated by the hard constraint + (spawner-first ordering; flag defaults to in-pod loop; #3049 now rejects + unordered overlapping slices at ingestion). +- **Cold-start latency per event** — pod + worktree attach on the hot path; + worktree reuse (Option B) is the lever. Needs an explicit per-event latency + budget in the plan. +- **Supervision gaps** — one-shot pods convert "loop retries" into + "orchestrator must respawn"; bounded-respawn policy (cq-2) prevents both + silent stalls and runaway spawn loops. +- **Monitor false positives** — health tripwires assuming long-lived pods + will misfire on ephemeral ones; thresholds must become + lifecycle-owner-aware in the same change that flips behavior. + +## Out of Scope + +- The agent primitive (pod image, Agent SDK, permissions, gateway + restrictions) — untouched. +- BRC protocol semantics (propose/ack/nack/confirm, Delphi redaction, + multi-reviewer NACK barrier) — unchanged; only *when a pod exists* changes. +- Extended prompt-cache TTL configuration — orthogonal, status quo preserved. + +## Related + +#2908 (foundation: event pump, compose_event_prompt, durable memory), #3017 +(declarative phase model, adjacent), #2958 (producer lifecycle, adjacent), +#2866 (k3s runtime, adjacent), #3002 (GKE split-object-store, adjacent), +#3023/#3041 (scrapped first attempt, fully superseded here).

The in-pod idle-budget alert +(`EGG_BRC_IDLE_BUDGET_MIN`, alert-only today) re-homes orchestrator-side: a +role whose actionable event has been pending longer than the budget (i.e. the +loop cannot make it progress) raises the same OVERSEER_ALERT shape from the +orchestrator, where the global judgment belongs. `heartbeat.py`: the +`HeartbeatCoordinator` session-refresh side effect (#2076/#2451) loses its +sender when no pod runs — under orchestrator ownership, session refresh is +not needed between events (sessions are per-spawn, slice 2); the coordinator +must tolerate absent senders without alarming.

Six slices on a single serialized chain: (1) EGG_EVENT_LOOP_OWNER ownership flag + a one-shot event arm in the consensus wrapper — when a pod is spawned in orchestrator-owned mode it executes exactly the injected event (propose|ack|nack), then exits; default 'pod' keeps the existing wait-loop byte-identical. (2) The orchestrator-side event loop + on-demand spawner: per-role _derive_next_action consumption moves orchestrator-side; propose|ack|nack spawn a deduped one-shot Job; confirm/complete are executed orchestrator-side with no pod (the wrapper already does them agent-free); spawn bookkeeping is stateless — re-derived from the message-store-rebuilt tracker on restart, with the dedupe key carried as a Job label so re-derived spawns are idempotent.

(4) Worktree re-attach and per-role gateway-session reuse across successive spawns — the per-event hot path drops worktree recreation and full session re-registration when the persisted worktree is healthy. (5) Lifecycle-aware monitoring: HealthMonitor thresholds keyed on the ownership mode ('no pod' is the normal state between events), the in-pod idle-budget overseer alert re-homed orchestrator-side as a convergence-stall judgment, HeartbeatCoordinator session-refresh accounted for at spawn time. (6) Docs + the flip follow-up package: architecture entry, proving-run procedure, and the prepared follow-up issue body (proving run with flag on -> flip default -> delete in-pod wait arm + heartbeat + flag in one cleanup PR) so retirement is scheduled work, not lingering deprecation. The chain is strictly serialized because slices 2/3/4 share orchestrator/kubernetes_spawner.py and the new event-loop module, and slice 5 judges the lifecycle that 2-4 define; no parallel root exists with a genuinely disjoint file set except docs, which still lands last so it documents the final shape.", + "hitl_bindings": { + "cq1_scope": "Option B — spawner + guard + lifecycle re-homing (worktree re-attach, session reuse, supervision, monitors, #2806 relocation).

Chose option (a) discard-on-attach over (b) dirty=>recreate to preserve the re-attach latency win \u2014 reset is cheap, recreate is not, and uncommitted residue is by definition unproposed work (committed-and-pushed state is the only durable BRC state), so discarding is correct. ac-4 now asserts an induced dirty-worktree case (predecessor killed mid-event with tracked + untracked residue; none of it reaches a subsequent commit) alongside the existing corruption/branch-mismatch cases; r-6 mitigation names the policy.

Read that diff as if you'd never seen the prior version. Apply your lens (security threat-model, concurrency races, contract AC, line-by-line bugs, silent-fallback shapes \u2014 whichever your role owns) to the delta itself, not to whether your previous concerns were satisfied. **Mandate 2 is bounded to this delta** \u2014 it does NOT ask you to re-traverse the whole accumulated surface from earlier cycles; that work was amortized when you first reviewed those commits.\n\nBoth mandates have equal weight. If (1) passes but (2) finds new issues, you NACK. ACK requires both pass.\n\n**The named-blockers anchor is a known trap. Every reviewer lens has a mandate-2 in its own territory** \u2014 security has newly-introduced threat surfaces, concurrency has newly-introduced races, contract has newly-introduced AC drift, code has newly-introduced line-by-line bugs. The four issues that escaped PR #2724 to the GitHub bot were all of code-lens shape (`${ANSWER}` as bare Python, deprecated `datetime.utcnow()`, non-atomic write, bare `except: pass`) \u2014 the persistent reviewer correctly answered mandate 1 (\"did prior issues get fixed? yes\") and skipped mandate 2 (\"does this delta introduce new issues? actually yes\"). The shape generalizes: whatever your lens, this delta can introduce issues your prior NACK didn't name. Watching the producer deliver a targeted fix pulls strongly toward \"verify my fix-request landed \u2192 ACK.\" Recognize the pull and do mandate 2 anyway.\n\n**How to execute mandate 2:**\n\n- Read each new hunk as an operator who's about to copy-paste / run / integrate it. Would this code execute as written? Would these docs send a copy-paster down a working path?\n- Apply every rubric pass to the new hunks. New issues outside the scope of your prior NACK are blocking; your prior NACK does not bound this re-review.\n- **Fresh-reviewer simulation.** Before issuing your v2 verdict, ask: would a reviewer who has only seen this delta (the commits since your last review) with no NACK history ACK this? If you can't argue yes from that diff alone, NACK.\n- **External-bot anchor.** Imagine `egg-reviewer[bot]` reads only this delta (the commits since your last review) with no NACK context. What would it flag? Anything it'd flag, you should NACK first.\n\n**Your v2 verdict must enumerate both halves** so mandate 2 doesn't silently disappear from the record:\n\n- (a) Which v1 blockers you verified-fixed (mandate 1).\n- (b) What new issues you audited-and-did-not-find (mandate 2). Name the specific shapes you checked \u2014 not \"reviewed thoroughly,\" but \"checked for silent fallbacks, doc-snippet executability, API-deprecation, atomicity of file writes.\" If you can't enumerate (b), you haven't done mandate 2.\n\n**Re-reviews are cheap by design.** Your amortized context means the work is \"read the delta, apply your rubric, decide\" \u2014 minutes, not hours. NACK without hesitance; the orchestrator absorbs cycles. Two NACKs on the same producer where the second names new findings is the correct trajectory, not goalpost-moving. The downstream GitHub reviewer should find nothing in this delta. Anything it catches that lives in this cycle's diff is a miss attributable to this re-review.", + "metadata": { + "payload": { + "summary": "v2 re-propose addressing risk_analyst's single blocker (R6 dirty-worktree gap).

Read that diff as if you'd never seen the prior version. Apply your lens (security threat-model, concurrency races, contract AC, line-by-line bugs, silent-fallback shapes — whichever your role owns) to the delta itself, not to whether your previous concerns were satisfied. **Mandate 2 is bounded to this delta** — it does NOT ask you to re-traverse the whole accumulated surface from earlier cycles; that work was amortized when you first reviewed those commits. + +Both mandates have equal weight.

The four issues that escaped PR #2724 to the GitHub bot were all of code-lens shape (`${ANSWER}` as bare Python, deprecated `datetime.utcnow()`, non-atomic write, bare `except: pass`) — the persistent reviewer correctly answered mandate 1 ("did prior issues get fixed? yes") and skipped mandate 2 ("does this delta introduce new issues? actually yes").

Would these docs send a copy-paster down a working path? +- Apply every rubric pass to the new hunks. New issues outside the scope of your prior NACK are blocking; your prior NACK does not bound this re-review. +- **Fresh-reviewer simulation.** Before issuing your v2 verdict, ask: would a reviewer who has only seen this delta (the commits since your last review) with no NACK history ACK this? If you can't argue yes from that diff alone, NACK. +- **External-bot anchor.** Imagine `egg-reviewer[bot]` reads only this delta (the commits since your last review) with no NACK context.
