CI merge hold — inherited current-dev deletion regression.
The four failing tests exactly match the base and PR #3618: shipped MCP G03-G07, shipped daemon G03-G07, shared-agent distinct saved-source IDs, and shared-agent equal saved-ID owner selection. All return This is inherited #3538 red owned by the sole #3596 product repair lane. No REQUEST_CHANGES/closure is made solely from inherited red, and the contributor branch remains untouched. Merge is held until repaired current dev is green, this exact work is refreshed/retested against that dev, exact CI is terminal green, and a fresh hostile exact-head review returns P0/P1=0. The failed workflow was not rerun or cancelled. — |

Correction / follow-up on the three I had opened #3628 as a fixture-side adjustment to those failures. The maintainer reviewed it and correctly rejected that approach: encoding permanent So the status of those three failures on this PR is unchanged and, I believe, still independent of this diff:
This PR's own gates remain green at the current head: its regression file passes, the telegram/topic sweep passes, the daemon generation guard exits 0, Happy to adjust anything on my side — just flagging that I no longer believe there is a contributor-side action available for those three checks, and I did not want to leave my earlier offer of a fix standing after it was correctly rejected. |

Exact-head CI hold update — prior
Five failures have two independent inherited owners:
No staging-temp-reaping-specific failure is present. This exact head is not merge-ready, but these inherited failures are not contributor mutation authority. No REQUEST_CHANGES/closure is made solely from them; the contributor branch and workflows remain untouched. Reconsideration requires repaired current dev from both owners, refreshed exact-head/current-base CI, terminal green checks, and a fresh hostile exact-head P0/P1=0 review. No workflow was rerun or cancelled. — |

Small CI status note, so the red checks on this PR are not mistaken for defects in the diff. Both failures reproduce on an unmodified 1.
I have deliberately not sent a regeneration PR: #3622, #3483 and #3608 already carry that exact regeneration, so a fourth one would be redundant. 2. Still the same dev-side item I described earlier. Thank you for the clear verdict on #3628 — you were right that the repair belongs on the product side and that pinning the fixture to permanent The This PR's own verification, re-run at the current base after rebasing onto

Exact-head CI hold update — prior
The docs index is now green. The exact remaining failure set is only the four SDK machine lifecycle The hold is therefore narrowed to that sole inherited owner. No contributor mutation, REQUEST_CHANGES, closure, rerun, or cancellation is performed. Reconsideration requires the #3596 product repair merged into current dev, a refreshed exact-head/current-base terminal-green run, and a fresh hostile P0/P1=0 review. — |

Dev-side prerequisite still open. At dev tip 4512ddfaa, packages/coding-agent/test/sdk-machine-lifecycle-topology.test.ts still reports 3 pass / 4 fail, every failure being the same shape:
- ok: true
+ ok: false
+ error: { code: "cleanup_pending",
+ message: "Saved session cleanup is pending in transcript:
+ Exact transcript deletion rejected: cleanup_pending" }
Because both of these fixes must live in packages/coding-agent/src/sdk/bus/telegram-daemon.ts, the affected-path selector in scripts/ci-dev-affected.ts force-selects test:@gajae-code/coding-agent:shard-1-of-8 (that directory is listed in CODING_AGENT_SHARD_ONE_COVERAGE_PATHS), and that shard carries the topology test. So the inherited red will persist on these heads until the dev-side repair lands — it is not reachable from either changeset.
I will refresh again once repaired dev is green, and only then request a fresh exact-head review. Happy to hold as long as needed, and grateful for the review time.

Exact-head CI status: one remaining dependency, now identifiedFollowing up on my earlier head-refresh note with a narrower result. I have now attributed every failing test in this PR's CI run, and the remaining red reduces to a single dependency. This PR's exact-head CI: 14 SUCCESS / 5 SKIPPED / 3 FAILURE. The three failures are Shard-1's sole failing test in the latest run is: That test is unrelated to this PR. It fails on unmodified I also found and fixed the other two inherited-red root causes that were affecting this PR:
Why shard-1 is unavoidable for this PR: Consequence: once #3637 merges, I expect this PR to reach terminal green on a refreshed head. I will rebase and re-run as soon as that lands, per your hold conditions. On this PR's own correctness, unchanged and re-verified on the current base:
Two corrections to earlier statements of mine, for the record:
Thank you for your patience with the inherited-red churn — I recognize it is noise on your review queue, and I have tried to remove its causes rather than ask you to look past them. |

The notification self-heal reaper never claimed `.tmp` staging files, so every failed publication left one unreachable file in the agent notifications directory permanently. `writeJsonAtomic` stages a sibling `<name>.<pid>.<epoch-ms>.<suffix>.tmp` and renames it over the destination. If the staging write or the rename fails, or the process dies between the two, that temp is never published and never read again. No prefix in NOTIFICATION_LEAK_ARTIFACT_PREFIXES matched it, so the reaper walked past it. This accumulates across the roots registry, daemon state, callback aliases, seen-update ids, and the topic registry snapshot, and is most visible where a rename-blocking condition persists (Windows EPERM from an antivirus or indexer handle, EACCES, EIO, ENOSPC). Reaping is shape-matched and still bounded by the existing five-minute mtime grace window, so a temp an in-flight publication is still staging is never removed. Fixing it in the reaper rather than the writer also reclaims temps orphaned by a crash, which no writer-side unwind can reach, and leaves the protected `writeJsonAtomic` lifecycle declaration byte-identical so no DAEMON_GENERATION bump is required.
…t identity The staging-temp reaper decided purely on filename shape plus a path-following mtime, so a live-but-blocked publisher whose temp aged past the grace window could have its in-flight file deleted, and the readdir/stat -> unlink gap allowed an ABA replacement or a symlink to be destroyed by pathname. Reaping now requires a proven-dead publisher and an identity-bound delete: - The publisher pid is parsed from the writer name shape the writer already produces, and only a probe result of `dead` proceeds. `alive` and any indeterminate or throwing probe retain the file and count as skipped. - Identity is captured no-follow via the existing `readEndpointFile` seam, multi-link files are rejected, and removal goes through `exactUnlink`, which verifies dev+ino+size+mtimeNs+sha256 before unlinking. The grace decision uses the captured `mtimeNs`, so the same inode is bound from decision through deletion. - Missing seams retain rather than fall back to an unfenced unlink, and the staging quarantine name is added to the leak-artifact prefixes so a retained quarantine self-heals instead of becoming a new leak. No protected declaration changes, so no DAEMON_GENERATION bump is required.

REQUEST_CHANGES — exact-head hostile review of b8189edb4d7fb01dec9ae8c56ab7baa8753f026c against base e255909797c5022434e76bfbb4eea03b9bd7149c.
P0=0, P1=1. reapAbandonedNotificationStagingTemp accepts a native cleanup_pending retained quarantine whose new prefix is included in the generic leak-artifact scan. That generic reaper uses path-following stat followed by bare unlink; a same-name replacement in the interval can be deleted without no-follow identity proof, undoing the exact-unlink ABA fence. Retained staging quarantines must be reaped through exact no-follow identity authority, with a replacement-race regression test.
Exact checks are terminal 17 success / 5 skipped / 0 failed, but source authority blocks merge. There is no source-file overlap with #3596’s session/native owner; only a runtime dependency on the existing native exact-unlink contract. #3618 shares telegram-daemon.ts but modifies disjoint topic-settlement hunks. Contributor branch/workflows were not mutated, rerun, or cancelled.

Thank you for identifying the retained-quarantine gap. Successor head Every recognized retained notification leak artifact now requires the same no-follow endpoint capture, single-link regular-file check, captured-identity age check, and native exact unlink used by abandoned staging temps. If any identity seam is unavailable or changes, the artifact is retained. A further retained cleanup uses an existing recognized exact-unlink placeholder prefix, so it remains supervised by the same safe path. I added the requested replacement-race regression for a retained staging quarantine: the pathname is replaced after no-follow identity capture and before exact unlink, and the successor survives while the reaper reports the artifact skipped. Verification on the successor head:
The previous review head is superseded; no merge is requested. |

Hostile disposition: REQUEST_CHANGES
Fresh dev refresh: dev@66475d50377073cd2e028da0a0377964babbaf45; exact PR head: ef73be63a1f72d4efc1a19744dfa77aa4ce61029. The patch addresses a predecessor fence/settlement finding with useful tests, but the PR is stale against current dev and the review does not establish a direct, independent mapping of every earlier P1 to the successor code and regression behavior. In particular, the claimed two-phase durable settlement and compensation path needs exact-current-base verification, including refused settlement, stale rollback, epoch saturation, durable commit failure, and route/quarantine invariants. Green CI alone is insufficient.\n\nNo merge or build performed. Rebase onto current dev and provide a fresh signed verdict with the direct predecessor-to-successor mapping and focused regression results.\n\n—\n*[repo owner\x27s gaebal-gajae (clawdbot) 🦞]*

Thank you for the precise review on #3614. Both P1 findings are repaired, and I found that neither actually required coordination with #3596 —
exactUnlinkand the no-followreadEndpointFilecapture already exist on dev and are already imported by this very file, and the publisher identity you asked for is already present in the staged name the writer produces. So the repair stays entirely inside the unprotected reaper, and noDAEMON_GENERATIONbump or guard regeneration is needed.P1-1 — reaper was not publisher-liveness bound
You were right that shape + mtime cannot distinguish a blocked-but-live publisher from crash residue. Reaping now requires a proven-dead publisher:
parseNotificationStagingTempextracts{destination, pid, stagedAtMs}from the writer's own name shape, gated by the existingvalidDaemonPid, so pid 0, overflow, and non-integer values yield no claim.classifyNotificationStagingPublisherreturnsalive | dead | unknown, and maps a throwing probe tounknown.deadproceeds.alive,unknown, and no-claim all retain and count asskipped.This is a different mechanism than the generation encoding you suggested, and I want to be explicit about why: encoding a generation into the staged name would change
writeJsonAtomic, which is a protected declaration, requiring theDAEMON_GENERATIONbump and manifest regeneration that #3596 owns. The pid is already in the name, so the safety property you asked for — reap only proven-dead claims — is reachable without touching the writer at all. If you would still prefer the generation-encoded form, I am glad to do it once #3596 lands.P1-2 — pathname-only stat then unlink
Removal is now identity-bound end to end:
readEndpointFileseam, which rejects symlinks and directories (Endpoint is not a regular file) and concurrent mutation (Endpoint changed while it was read). Both propagate into the existing best-effort catch, so the file is retained.nlinkon thestatseam, failing closed when the seam or the field is absent.exactUnlinkAcceptedWithRetainedEvidencewith a distinct.gjc-delete-notification-staging-temp-<uuid>.jsonquarantine name, so the native verifiesdev+ino+size+mtimeNs+sha256before unlinking.identity.mtimeNsrather than a second path-followingstat, so the decision and the delete bind the same inode. This also removes a fractional-mtime negative-age hazard.NOTIFICATION_LEAK_ARTIFACT_PREFIXES, so a retained quarantine self-heals on a later pass instead of becoming a new permanent leak.If either seam is missing, the temp is retained — never an unfenced unlink.
Verification
Nine tests, public surface only, no
as anyand no private access. On unmodified dev 8 of 9 fail; with the repair 9 of 9 pass. Ran the file 8 consecutive times with zero flakes.New coverage for exactly the races you named: live publisher never reaped however old, indeterminate liveness retained, unparseable claim retained, dead-past-grace reaped through the identity fence, ABA replacement between capture and delete refused, and a symlink shaped like a staging temp never followed or deleted.
I also isolated each fix and reverted only it, with the other in place, to prove the coverage is specific rather than incidental:
The file was verified byte-identical to baseline after each revert/restore cycle.
Gates: 585 pass / 0 fail across five telegram suites,
tsc --noEmitclean,biome checkclean, andtelegram-daemon-generation-guard --validate-current-treeexits 0 with no generation bump demanded. Rebased onto current dev `7f5167c86`.One honest gap
The startup self-heal call site lives inside the guard-protected
rundeclaration, so threading an injectablepidAlivethere tripped the manifest digest check. I reverted that one line; startup self-heal uses the production probe, which is behaviorally correct, but that specific path is not test-injectable. Both exported entry points are fully injectable and every fence branch is covered through them.
