Code Review Summary
Reviewed the complete diff from 6be0e3337aa3e16cf6537cf2cf7246b872316dfb through exact head 1663182bb1d29dca92a857ae85c47f1986fc8ea6 against issue-inbox #1040 and the renderer-memory-containment PRD.
Findings
[MEDIUM] Direct entry does not install the process owner until after asynchronous startup work
File: src/server/production-server.ts:434
The direct import.meta.main path performs OTLP/cache initialization, runtime detection, and bootstrapProd() before it calls runProductionProcessOwner() at line 473. SIGINT/SIGTERM during any of those awaits therefore bypasses the coordinator, so this entry point does not provide the required startup/shutdown race behavior or the same exactly-once drain/flush/exit ownership as the compiled CLI.
Fix: move the asynchronous initialization and bootstrap into the owner start boundary, keep any acquired bootstrap handle available to shutdown, and add a direct-entry seam test proving a signal during pending bootstrap is coordinated once and disposes any resources acquired before the signal.
[MEDIUM] Compiled CLI shutdown skips disposal of its internally owned bootstrap
Files: src/server/production-server.ts:230, src/server/production-server.ts:365, cli/commands/serve/command.ts:301
When the compiled CLI calls startProductionServer without a supplied bootstrap, that function creates one internally. Its returned stop stops monitoring, the rejection guard, and the listener, but never calls bootstrap.dispose. The CLI graceful-shutdown call can pass only server.stop, so extension teardown and FS adapter resources described by BootstrapResult.dispose are not released before process exit. The direct entry explicitly passes dispose: bootstrap.dispose, which exposes the mismatch. This misses the PRD requirement that compiled process-owner cleanup stop bootstrap resources.
Fix: make bootstrap ownership explicit and dispose an internally created bootstrap exactly once from the returned lifecycle handle; leave a supplied bootstrap caller-owned so the direct path does not double-dispose it. Add regression coverage for compiled/unsupplied bootstrap teardown during memory and signal shutdown.

Code Review Summary
Reviewed the complete diff from 6be0e3337aa3e16cf6537cf2cf7246b872316dfb through exact head 9b3dde209e515f990c35c2b2fd2e3c5b6e926206 against issue-inbox #1040 and the renderer memory containment PRD.
Finding
[MEDIUM] A server that finishes starting during shutdown escapes lifecycle cleanup
Files: src/server/production-shutdown-coordinator.ts:95-98, src/server/production-shutdown-coordinator.ts:115-116, src/server/production-server.ts:484-490
When a signal arrives while start() is pending, the coordinator invokes shutdown with the current server value. If startup resolves while shutdown is draining, line 116 stores the new server, but the in-progress shutdown still holds the earlier undefined. The direct owner similarly evaluates bootstrap?.dispose when shutdown begins. The late listener is therefore never stopped and a late bootstrap is never disposed before telemetry flush and process exit. The new hung-startup test cannot expose this because its startup promise never resolves.
A pinned-Deno 2.7.7 adversarial lifecycle run reproduced the ordering as start -> shutdown(server missing) -> start resolves -> flush -> exit, with no stop call.
Fix: make shutdown join the startup/resource-acquisition handoff, or make the startup path observe cancellation and dispose any resources acquired after shutdown begins. Ensure late server/bootstrap cleanup is idempotent and completes before flush/exit. Add a regression where a signal fires during pending startup, then startup resolves before shutdown cleanup completes, and assert the late server and bootstrap are each released exactly once.
Verification
- Pinned Deno 2.7.7 focused tests passed: 6 suites, 107 steps covering sampler policy, coordinator, direct owner, bootstrap ownership, admission, and CLI ownership.
- Pinned Deno 2.7.7 checks passed for all modified production files and new/focused test entry points; the repository test-typecheck ratchet passed with 36 grandfathered files and zero new failures.
- Modified-file lint, formatting, and
git diff --checkpassed. - Direct checking of
tests/integration/server/production-server.test.tsstill reports its two grandfathered pre-existing diagnostics; blame confirms both predate this branch. - No hardcoded secrets, dependencies, chart activation, live resource changes, or default-on path were added.
- The implementation otherwise covers strict opt-in configuration, sustained RSS sampling, one-shot notification, readiness/admission behavior, active stream drain, signal/memory convergence, embedded opt-out, and rollout limits.

Code Review Summary
Re-reviewed the complete diff from 6be0e3337aa3e16cf6537cf2cf7246b872316dfb through replacement exact head e13eaa057d9ff1dcd8c02db87ee2a6d0718ff789 against issue-inbox #1040, the renderer memory containment PRD, and the prior exact-head finding.
The replacement correctly aborts startup when shutdown begins without a server, owns server stop exactly once, stops a server acquired during the shutdown callback, and dynamically disposes direct-owner bootstrap resources. One adjacent ordering window remains.
Finding
[MEDIUM] Startup resolving during telemetry flush can still exit before late cleanup completes
Files: src/server/production-shutdown-coordinator.ts:107-118, src/server/production-shutdown-coordinator.ts:133-136, src/server/production-server.ts:494-507
The coordinator performs its final late-server recheck at line 115, then starts flush. If pending startup resolves during that flush, the startup continuation calls the exactly-once server.stop(), but the coordinator does not await that new promise before exit(). The direct owner has the same boundary for a bootstrap acquired during flush: both dynamic disposal checks run inside shutdown, before the flush starts.
A pinned-Deno 2.7.7 adversarial run reproduced: shutdown(server missing) -> flush starts -> startup resolves aborted -> stop starts -> flush completes -> exit -> stop completes. This violates the stated ordering that listener/bootstrap cleanup completes before telemetry flush and process exit. The new regression resolves startup inside the shutdown callback and uses an immediately resolved stop, so it cannot expose this later and slower interleaving.
Fix: add a post-flush lifecycle recheck/join that awaits any late server stop and dynamic bootstrap disposal before the synchronous exit boundary, without waiting indefinitely for startup that remains pending. Add a regression that resolves startup during a blocked flush, keeps stop/dispose pending, and asserts both complete before exit.
Verification
- Pinned Deno 2.7.7 focused lifecycle tests passed: 3 suites, 10 steps.
- Pinned Deno 2.7.7 checks passed for all five replacement production/test files.
- Modified-file lint, formatting, and full-branch
git diff --checkpassed. - The full branch remains default off, strictly configured, embedded-opt-out safe, and scoped away from charts/live activation.
- CI was still in progress at review time; successful checks already included format, typecheck, test layout, npm compatibility, proxy binary, RSC browser E2E, and Sentry runtime packages.

Code Review Summary
Re-reviewed the complete branch from 6be0e3337aa3e16cf6537cf2cf7246b872316dfb through exact head 679335b1d85c741c941a2f0676c5ac186b47a2e4 against issue-inbox #1040, the renderer memory containment PRD, and both prior lifecycle findings.
The new post-flush hook fixes the tested case where startup assigns the server before flush completes, and the direct bootstrap regression proves disposal completion before exit in that ordering. One microtask ordering remains uncovered.
Finding
[MEDIUM] Same-task flush/startup settlement can still exit before late server stop completes
File: src/server/production-shutdown-coordinator.ts, post-flush beforeExit callback
The callback checks server before awaiting options.beforeExit. If flush and startup settle in the same task with the flush continuation queued first, that check sees no server. Its await options.beforeExit?.() yields, startup then assigns the server and begins the exactly-once stop, and the callback resumes into exit() without awaiting that pending stop.
Pinned Deno 2.7.7 exact-head reproduction:
shutdown:none -> flush-start -> flush-resolve -> start-resolve:aborted=true -> stop-start -> exit -> stop-done
The added regression resolves startup and waits for its continuation before completing flush, so it guarantees the server exists at the first post-flush check and misses this queue order.
Fix: perform the final if (server && shutdownRequested) await server.stop() after await options.beforeExit?.(), immediately before returning to the synchronous exit boundary, or add an equivalent final join with no later await. Add a regression that resolves flush first and startup second in one callback, blocks stop, and asserts stop-done precedes exit.
Verification
- Pinned Deno 2.7.7 focused lifecycle tests passed: 3 suites, 12 steps.
- Pinned Deno 2.7.7 checks passed for all five relevant production/test files.
- Modified-file lint, formatting, and full-branch
git diff --checkpassed. - The full branch otherwise satisfies the reviewed default-off configuration, sampler, readiness, admission, drain, embedded opt-out, documentation, and scope boundaries.
- CI was in progress at review time; format and typecheck were already successful.

Problem and behavior
Long-lived renderer processes retain evaluated module generations and can exhaust memory. This PR adds disabled-by-default RSS-triggered graceful recycling as containment; durable generation retirement remains tracked in veryfront/veryfront-issue-inbox#1035.
An explicitly enabled, valid policy requests one process-owner shutdown after sustained RSS pressure. Tenant admission closes before interception or project loading, health/readiness probes remain responsive during unfinished initialization, and admitted streams drain. Cleanup and telemetry are attempted within one bounded deadline before exit. Late readiness failures are observed, and late owned resources are joined at the terminal exit boundary while time remains.
Bootstrap supplies the authoritative policy, including mixed parent/project
.envvalues and supplied adapters. CLI, direct and public coordinator paths use consistent deadlines; failing deadline callbacks cannot strand shutdown. A short drain cannot consume the cleanup budget through an oversized polling interval. Custom finalizers cannot replace mandatory owned cleanup.Verification

Recycling is disabled by default; activation configuration has not been enabled. No chart values, quotas, requests/limits, replicas, HPA or live resources change. Activation requires native Linux startup/warm/drain measurements, a threshold with native/child-memory margin, a canary, fleet staggering and node/N-1 placement checks. PDBs and Deployment surge settings do not serialize self-initiated container exits. If cleanup exhausts its budget, the process aborts and exits; further cleanup is best effort.
