[nissa-seru]

This PR fixes the places that still assume context-manager 0.13's contract, though agent-framework has required ^0.14.0 since 0.21.1, and the places that remove a single message from a body, which context-manager refuses:

• Context maintenance no longer fails for every agent when one agent's context manager refuses its readiness query. That agent's run records the error and the agent gets its own alert, once for a failure that lasts, while the others run. An operator surgery or branch switch now waits for running maintenance, a pass or an over-budget drain kick, before it moves the branch.
• resume() no longer throws when one agent's runtime settings can't be read. It warns, naming the agent, and proceeds without a feasibility verdict for that agent. While a surgery holds the store, it refuses as busy, including when the surgery took the store while resume() waited.
• Offline recovery reads a sharded body the way 0.14.0 does. It accepts two selections it used to refuse.
• Removing a message stored as a body, a one-shard body's included, no longer fails: in offline recovery, a resumed Discord suppression, the host hide command, a module's removal (a message deleted on Discord) and the coalescer's. A rewind takes the whole exchange, bodies included, in one removal.

It also adds notes for operators and hosts to CHANGELOG's 0.21.1 section, about what context-manager 0.14.0 changed for them, including stores whose estimator calibration 0.14.0 can reject. No dependency changes.

Merge order: after #286, and before the fix for #326 (below).

Why these places

context-manager 0.14.0 refuses most of its methods while its strategy's initialization is pending or has failed. Initialization is pending only inside ContextManager.open, switchBranch, fork and setStrategy, and a failed one leaves the manager refusing until a successful switchBranch or setStrategy. The refused methods include isReady, getPendingWork and getHotContextSettings, which 0.13 always answered. A strategy can also refuse on its own: the autobiographical strategy refuses its queries for a branch it hasn't reloaded.

0.21.1 raised the floor to ^0.14.0 and changed nothing else, so:

1. The maintenance pass read every agent's isReady while building its queue, outside any guard. One agent whose manager was mid-switch or had failed to initialize ended the whole pass. No agent's maintenance ran, and the pass raised one alert for the whole pass (scope: 'pass'), on every pass, every few seconds by default, for as long as the manager stayed refused.
2. resume() reads each agent's runtime-settings preview for its feasibility check. One agent's refusal threw out of resume() before any verdict, and force couldn't get past it.
3. 0.14.0 reads a body pairwise in store order. A message continues the body before it only when it carries the same group id at a higher shard index (continuesBody). A document posted twice is stored as two copies under one group id, and 0.14.0 reads the copies as two bodies. Offline recovery compared group ids alone, which 0.14.0's changelog asks hosts to stop doing.

Separately, context-manager's removeMessage refuses any message that carries a group id, a one-shard body's included, and has since before 0.11. Four places in agent-framework removed a single message with it, and each failed on a shard.

What changes

Context maintenance (src/framework.ts)

• The pass reads each agent's readiness through one helper that catches a throw. An agent whose readiness can't be read gets the error on its run record (error) and its own context-maintenance-failed alert with scope: 'agent', and sits the pass out. The other agents run. Anything else that throws while one agent's maintenance is prepared, such as its tool refresh, is that agent's failure in the same way.
• The readiness read after an agent's ticks goes through the same helper. A refusal there is reported for that agent, unless one of its ticks already failed: a run records an agent's first failure, and the next pass reads the agent again.
• A refusal inside an agent's ticks is that agent's error and alert, as any tick failure is.
• A failure that lasts meets every pass. Each run records it, and it is logged and alerted once. It is alerted again when its whole text changes; every 15 minutes while it lasts, the alert webhook's cooldown for it, counted from the webhook's last post of it, so a report of changed text that the webhook didn't post doesn't push the reminder back; or after that agent's maintenance has gone without a failure, meaning a pass that finds it ready, or one whose ticks and readiness read succeed.
• While an operator surgery (rollbackToMessage or suppressMessages) or switchBranch holds the store, no pass starts and no over-budget drain kick starts, and a running pass or kick starts no new tick. The operator call waits for them to finish before it switches or forks the branch, so no maintenance work overlaps the move. Maintenance makes no provider call meanwhile. One made then, or one waiting at the agent's provider gate when the hold is taken, is withdrawn without being sent. Such a call waits behind a cooldown, or behind the retry turn a cooldown queues, which the hold keeps from starting, so waiting for it could wait for good. A withdrawal is no maintenance failure, and context-manager counts no attempt for it. A merge keeps its queue entry, so the next tick after the hold does it. A chunk's compression has already left its queue: context-manager logs "Failed to compress chunk (hierarchical)" with the withdrawal and records the call. The chunk, still uncompressed, is queued again at that manager's next rebuild: the switched manager's own initialization, or another agent's next message or sent compile. So the operator call's wait is at most the provider calls already in flight. A pass waits for every agent's work to settle before it ends. The store moves that take no reservation, the API's branch.switch, undoLastTurn and redo, are After a surgery or branch switch, the other agents on the store can't compile until the host restarts #326's. A failure the pass meets meanwhile is reported as any other. maintenanceTick() answers ran: false with a warning that names the surgery.
• getContextMaintenanceSnapshot() reports an agent whose readiness can't be read as ready: false with an error. A strategy whose getProgressSnapshot throws reads as having no progress, in the snapshot and in the pass's records.

The API server (src/api/server.ts)

• switchBranch now moves the store once maintenance already running has finished, so a switch's move can come after the call returns. The API server reads the store's branch whenever it reports one: branch.current, the branch list, /health, /status and a client's welcome. It keeps the last name it read only for once the store has closed. branch.switch announces its own move, from the branch it began on to the one it was asked for, once the move is made. One that fails after moving the store still announces it, and a refusal announces nothing.

resume()

• A throw from one agent's settings read is caught. resume() warns, naming the agent and the error, and gives that agent no verdict, as it already does for a preview that isn't available. The verdict guards against returning an agent that would run over budget, and an agent whose manager refuses its compiles can't run. That manager refuses the agent's turns and writes until a switchBranch or setStrategy succeeds, and the maintenance pass reports it.
• While a surgery holds the store, resume() refuses with OperatorActionError (agent-busy), as the other operator calls do, since the manager the surgery is switching refuses its settings read until the switch is done. It checks on entry and again after its waits for a pass or a preview, before it reopens anything, so a surgery that took the store meanwhile is refused too.

Offline recovery (src/recovery/offline-branch.ts)

• The anchor check asks continuesBody(anchor, next). An anchor at the end of one copy of a reposted document is accepted, and an anchor inside a copy is still refused.
• The removal check reads each message against the one before it, in store order and across scan windows. A selection splits a body when a message that continues the one before it lands on the other side. Suppressing one copy and keeping the other is accepted. A selection inside one copy is still refused, including one that crosses the edge of a 1,000-message scan window.
• An anchor at the end of a write that was cut short keeps that partial body and leaves out its retry, which 0.14.0 reads as a body of its own.

Removing one message of a body (src/stored-removal.ts)

• removeStoredMessages removes a single message outside any body with removeMessage, and a shard, or any longer interval, with removeMessages, which refuses an interval that splits a body. removeStoredMessage removes a message by its id, with the rest of its body when it's in one. It finds the body in blob-free windows, as the live surgeries do, rather than reading the whole branch with every attachment on it, once for each message a sweep removes.
• Offline recovery's suppressions and a Discord suppression resumed after a crash go through it. Each called removeMessage for a single message, so suppressing a one-shard copy failed at removal.
• A module's removeMessage, which the Discord module calls for a message deleted on Discord (live, in its sweep, and at reconcile), and the coalescer's removal of an unread message it replaces go through removeStoredMessage. A long message, stored in shards, used to stay in context when it was deleted.
• The host hide command hides a message stored as a body whole, and every stored copy of it: a write cut short and retried leaves a partial body before the whole one, both carrying the Discord id. Only a message that carries a Discord id matches. Its reply counts a body once and lists each Discord message once. Its range form widens both ends to whole bodies. Its operator-log entry lists at most 50 of the ids it removed, with removedIdsTruncated when there were more, as the range form's does. While a surgery holds the store, it refuses, as the other operator calls do.
• An automatic rewind whose newest message is the last shard of a body takes the whole body (bodyBoundsIn) and describes it whole. A tool result's paired tool_use turn is taken whole too, since a turn stored as a body carries its tool_use on its first shard, and the exchange goes in one removal, so a refusal can't leave it half applied. It used to fail at removal.

Changelog

• changelog.d/cm-0.14.changed.md, changelog.d/cm-0.14.fixed.md and changelog.d/body-removals.fixed.md describe the changes above for the next release.
• CHANGELOG's 0.21.1 section gains two notes, marked as added after the release. They belong there because 0.21.1 is the release that brought 0.14.0 to hosts, and a fragment would put them in a later release, after hosts on 0.21.1 or 0.22.0 had already upgraded.
  • For operators: 0.14.0 stamps its persisted calibration multiplier with the pricing it was learned under, and two kinds of store can then refuse every compile with OverBudgetError. The note says how to tell the two apart and points at the Operators entry of context-manager 0.14.0's changelog for the repair.
  • For hosts: what else 0.14.0 changed: dry-run compiles leave the estimate and calibration alone, the state queries throw while initialization is pending or has failed, and a reposted sharded document misses the prompt cache once after the upgrade.

Where else agent-framework meets the refusals

Each of these was read at this PR's base and left as it is:

• Operator reads and writes of an agent's settings (getRuntimeSettings, the runtime-settings preview, updateRuntimeSettings, resetRuntimeSettings and cancelRuntimeSettingsTransition). During a switch, or after a failed initialization, the operator gets context-manager's refusal, which names the branch and how to recover.
• A module's editMessage reaches the primary agent's manager, and a refusal comes back to the module.
• The API server's message.list and agent-context commands compile through the context manager, and a refusal comes back as the command's error.
• The semantic history index catches a refusal in its sync, logs it and backs off, as it does for any failure.
• The history tools run inside turns, and an operator surgery reserves the store while it switches, so no turn runs then.
• The over-budget drain breaker's ticks. A refusal there ends that kick and is logged, and the next over-budget failure kicks again. While a surgery holds the store, no kick starts, and one running stops ticking.
• A deferred write for an agent whose manager refuses. On main, the resume flush logs it and drops it from the durable queue, and the withdrawn-turn flush at a turn's start throws at the first refused write, losing the rest of its drained batch. Since this PR lets resume() go on past an agent whose manager refuses, it merges after fix(deferral): hold window-only messages to the turn's end; injected messages are read #286, which keeps a write that can't be stored in its agent's queue on every flush path, holding what's queued behind it.
• Every other agent on the store, after the branch moves. An operator surgery moves the branch through the named agent's manager, and branch.switch, undoLastTurn and redo move the store directly. Each manager that didn't make the move keeps its strategy loaded for the old branch, and the autobiographical strategy then refuses until it's re-initialized, on context-manager 0.13 as on 0.14. That's After a surgery or branch switch, the other agents on the store can't compile until the host restarts #326, whose fix re-initializes those managers and merges after this PR. Until then, this PR keeps maintenance running for the agents that can. The direct moves don't hold the store, so they don't wait for a maintenance tick either; After a surgery or branch switch, the other agents on the store can't compile until the host restarts #326's fix gives them the reservation.
• A surgery whose switch fails restores the source branch with switchBranch, which re-initializes it. If the restore fails too, the operator's error says so, as before.
• The live suppression already removes a body as a range.
• A module's or the coalescer's removal during a surgery doesn't check the hold, as on main. It lands on the branch the surgery is leaving, or is refused mid-switch, and the Discord module's sweep tries again later.
• A module's removal of a message stored twice, a write cut short and then retried, takes the body its id names and leaves the other copy, which carries the same Discord id. hide takes both. Taking both on a module's removal would need a removal by Discord id.

Tests

• test/maintenance-timer.test.ts:
  • an agent whose manager failed to initialize, beside a healthy one; a tick that fences its own manager; a strategy whose readiness and progress queries throw; a throw while one agent's pass is prepared;
  • a failure that lasts: alerted once over several passes, and again after each way it ends; again when its text changes, including two long texts that differ only in their middle, and once the alert cooldown has passed;
  • a readiness refusal after an agent's last tick, reported once from the pass's end, and a run that keeps an agent's first failure only;
  • a rollback, a suppression and a branch switch that begin during a tick: the branch stays until the tick ends, no tick starts under the hold, and resume() refuses as busy meanwhile; a rollback that takes the store while resume() waits for a tick, refused by resume() after the wait; a rollback that waits for an over-budget drain kick's tick, after which the kick ticks no more;
  • no pass while a surgery holds the store, counted over the timer's passes; a pass that starts no new tick once the hold is up; a pass that ends before its agent is ready;
  • a rollback, a suppression and a branch switch that each finish while a maintenance call waits at the provider gate behind a queued retry: the call is withdrawn having sent nothing, and nothing is reported as a failure; a call made under a hold, withdrawn whether the gate is open or closed, and admitted again once the hold is released;
  • with the real alert path and a recorded webhook, a failure posted at minute 0 whose text changes at minute 14, posted again with the changed text once 15 minutes have passed since the post.
• test/stop-with-host-operations.test.ts: an API switch made while a pass runs leaves the store and the current branch on main until the pass ends, then announces main to side, with the current branch side.
• test/host-quiesce.test.ts: resume() with an agent whose manager failed to initialize, and the warning that names it; maintenanceTick() while a surgery holds the store.
• test/offline-recovery-branch.test.ts: two copies of one document, for an anchor at the end of a copy, an anchor inside a copy, a suppression of one copy (reopening the recovered store to check which copy remains), a suppression that splits a copy, a split across a scan window's edge, a one-shard copy, a plain message removed alone beside a one-shard copy removed as a range, and an anchor at the end of a write cut short before its retry.
• test/discord-awareness-outbox.test.ts: a resumed suppression removes a one-shard body as a range and a plain message alone; it skips an interval that committed before the crash and refuses one only partly present.
• test/operator-surgery.test.ts: hide removes a one-shard body, a three-shard body counted once, and a cut-short copy with its retry; its range form widens both ends; it refuses under a reservation, "undefined" matches none of two id-less messages, and the held message hides once the store is let go; a module's removal of a body's shard takes the body, with no full read of the branch; a single hide of a 60-shard body logs the first 50 ids and removedIdsTruncated; a rewind takes the whole body of its newest shard, and a sharded tool exchange in one range.

Evidence

At fb8a6c4f, which contains main at cd036e0d, each test file in its own node --test process on a Linux VPS, after a clean typecheck and build, with context-manager 0.14.0 and membrane 0.5.87:

• The full suite: 2181/2181 on Node 24.21.0 unforced and on Node 20.20.2 with --test-force-exit. On Node 24 with --test-force-exit, as CI runs npm test, 2166 ran and passed: it cut agent-runtime-settings short (40 of 55), which passes whole unforced (npm test's --test-force-exit can end a test file before its tests report, so a short run still passes #294).
• The last round's tests against the code before it: with framework.ts, api/server.ts and stored-removal.ts put back to d71370d5, all nine tests the round adds or extends fail: six in maintenance-timer, two in operator-surgery and one in stop-with-host-operations. Nothing else in those files fails.
• Removals: each of 44 pieces of the change was taken out on its own, and the nine test files that cover them were run: 43 at 194b17a6, and the withdrawal's pieces again at fb8a6c4f, with the loop's own. 42 fail a test. Two don't:
  • hide's widening of each matched copy to its body. context-manager's chunker gives every shard of a body the message's metadata, so matching every stored message by its Discord id already takes each whole body, and the widening only guards a body whose shards don't all carry the id.
  • Leaving what the failure reports remember untouched after a withdrawn pass. No test pins it. Clearing it would only let a lasting failure's next report count as new.
• ca2f8068, after fb8a6c4f, changes only test/maintenance-timer.test.ts. Six tests now read the first pass the timer recorded rather than the newest, since on a busy machine a second pass can end before the read. One of them failed that way in a cross-package run. The file passes 27/27 against context-manager 0.14.0 and against its main at 58a3f9e.

Greptile's reviews of this pull request and of #353, which is built on it, found the five problems that 3abf2bd1 to 609b247d fix: a surgery's wait for maintenance parked at the provider gate, the API server's branch read before the move, the reminder's count, the full read in removeStoredMessage, and the single hide's log.

Read by Gladys-2413 (Claude Opus 5.5), who read every round and ran the changed files on both Nodes. Her probes found the two hide gaps this pull request closes: hide under a surgery's hold, and a missing Discord id read as "undefined". Her read of the answer to Greptile found that its text said context-manager keeps a withdrawn chunk's work queued, which holds for merges alone, and suggested the loop the gate's wait now takes (fb8a6c4f).

@antra-tess, @Anarchid: I'll merge it once its checks pass on its merge with the then-current main, after #286, and not before 2026-10-15 16:00 UTC, unless you'd like changes first.

Fix with agent prompt

### Issue 1
src/framework.ts:3416
A branch change can wait forever when a running drain has a compression call parked behind a cooldown started by a primary call. The branch change takes `surgeryHold` before awaiting `settleMaintenancePass()`. When the cooldown ends, it queues a primary turn without releasing the parked compression call. That turn cannot start under `surgeryHold`, so neither side can finish. The store stays reserved and every agent stays paused.

Cancel or release parked maintenance work before waiting while holding the store.

### Issue 2
src/framework.ts:3571-3572
The new cache starts its cooldown even when `opsAlert()` suppresses the webhook post. A post at minute 0 followed by changed error text at minute 14 moves `reported.at` to minute 14. The webhook suppresses that changed report, and this cache then blocks the reminder due at minute 15 until minute 29.

Keep webhook reminders tied to the last actual post. Test this path with the real `opsAlert()` rather than replacing it.

### Issue 3
src/stored-removal.ts:35-38
`removeStoredMessage()` now calls `getAllMessages()` for every body deletion, although it only needs the body’s IDs and boundaries. This loads every attachment on the branch. Discord’s history sweep calls this helper once per deleted message, so deleting several bodies repeats that full read and adds memory and CPU work.

Find the target with blob-free windows and use `alignToBodyGroups`, as the existing surgery helpers do.

### Issue 4
src/framework.ts:7096
A single `hide` can now remove many shards and stored copies, but it writes all of `hiddenIds` to the operator log and trace. Hiding a large document can therefore create an oversized record and broadcast the same large list to listeners.

The range form already uses `capIds()` to enforce the 50-ID limit. Apply the same cap and `removedIdsTruncated` flag here.

Summary

This PR adapts maintenance and recovery to context-manager 0.14 and makes message removal work with stored bodies.

• A refusing agent no longer stops maintenance for every agent.
• resume() keeps going when an agent’s settings cannot be read.
• Offline recovery treats reposted copies as separate message bodies.
• Removing a message stored in shards now removes its whole body.

Known/deferred per nissa-seru: refused-write retention belongs to #286; sibling-manager refresh and direct branch-move reservations belong to #326. Module/coalescer removals during surgery and module deletion leaving another stored copy are acknowledged and unchanged. Existing settings/API refusals, derived summaries, and failed-restore behavior are intentionally unchanged.

Review was source-only; no tests were executed.

[nissa-seru]

Real, and fixed in 3abf2bd1, with fb8a6c4f on top. Maintenance makes no provider call while a surgery holds the store. Taking the hold wakes every call parked at a provider gate, and each one, finding the hold, is withdrawn without being sent. A call made under the hold is withdrawn before it can park, and one woken while its gate is still closed parks again rather than going out. The surgery's wait is then at most the provider calls already in flight. A withdrawal is no maintenance failure, and context-manager counts no attempt for it. maintenance-timer covers a rollback, a suppression and a branch switch, each with a call parked behind a queued retry, and each finishes. #​353 adds an undo and a redo.

Real, and fixed in ebef76ee. The same failure again now counts from the webhook's last post of it (opsAlertLastSent), and from its last report only when no webhook is set. So a report of changed text that the webhook didn't post no longer pushes the reminder back. The test uses the real opsAlert with a recorded webhook: a failure posted at minute 0, whose text changes at minute 14, is posted again with the changed text once 15 minutes have passed since the post.

Real, and fixed in 5985987f. removeStoredMessage now finds the message with the surgeries' blob-free tail scan, and takes its body's bounds from alignToBodyGroups, which reads a body as context-manager 0.14's body-runs rule does.

Verdict: approve. Six minor findings, none blocking; the release coupling is already enforced by hold #345.

The core of the PR is right on both questions it sets out to answer. Every place that removes one stored message now goes through body-aware helpers that match context-manager's actual contract, in 0.14.0 and 0.14.1 alike (the relevant context-manager, message-store and body-runs builds are byte-identical between the two). The maintenance pass, resume() and the snapshot now absorb a refusal from one agent instead of failing for every agent. What remains is edge cases and stale prose: hide's range form misses a later stored copy of the message at its end; conversation agents' maintenance isn't withdrawn under the hold; one docstring still states the 0.13 contract; and the 0.21.1 operator note doesn't yet say what context-manager 0.14.1 changes about it.

No earlier review from us on this PR, so there are no prior findings to dispose of.

The two questions

Is every remaining context-manager 0.13 assumption found and fixed? Almost all. I swept src/ for every method context-manager 0.14.1 guards with requireInitialized (isReady, getPendingWork, getHotContextSettings, previewContext, tick, removeMessage(s), addMessage, editMessage, fork, branchAt, summary queries and others), for group-id equality comparisons, and for single-message removeMessage calls:

• Fixed by this PR: the maintenance pass, resume(), getContextMaintenanceSnapshot(), offline recovery's body reads, and every removal site.
• Listed in the PR as deliberately left alone, and they behave as described: turn paths, the history module (its handleToolCall and semantic catch-up both catch), API message.list and agent context, and runtime-settings operations.
• Two places still carry the 0.13 contract: previewAgentRuntimeSettings's documented "never throws" contract (R1-3), and the 0.21.1 operator note, which describes 0.14.0's calibration load rather than 0.14.1's (R1-4).
• No group-id equality comparison remains in src/. The only bodyGroupId reads left are error text and isUnreadStoredMessage's conservative exclusion of bodies.

Is removing a message stored as a body correct for existing stores? Yes, for every store context-manager has written:

• bodyGroupId and shardIndex were introduced in the same change (first released in 0.10.0).
• Every release from 0.10.0 through 0.14.1 passes the message's metadata to every shard's append (e.g. 0.13.0 src/context-manager.ts:457-469). So continuesBody reads legacy bodies correctly, and every shard carries the Discord id.
• Ingress sharding happens only for more than one shard, so a one-shard body arises only from a write cut short.
• removeStoredMessages uses removeMessage only for an ungrouped single message, which is the only case context-manager accepts (message-store.ts:617-621).
• bodyGroupRun's alignToBodyGroups widening uses the same pairwise bodyStart/bodyEnd as removeRange's bisection check (message-store.ts:839-846, 706-718), so the helper and the store can't disagree about where a body ends.

The one gap is hide's range form with a twice-stored endpoint (R1-1).

Facts the PR depends on, checked

• context-manager 0.14.1 is the current release: npm latest, tag v0.14.1, CHANGELOG dated 2026-10-15.
• agent-framework has declared ^0.14.0 since v0.21.1 (v0.21.0 declared ^0.13.0; v0.22.0 and v0.22.1 declare ^0.14.0). A fresh install of this head resolves context-manager 0.14.1.
• #365 raises the floor to ^0.14.1, and is still open. This PR widens the case #365 and release hold #345 exist for: hiding or removing a body now succeeds instead of being refused, and hide answers with a dry-run preview (lastVisiblePreview → previewActivation), which is the "dry compile first after a removal" sequence that 0.14.0 mishandles.
• scripts/release-holds.mjs on main stops any release while #345 is open, so main can't be released with this PR and without #365. Nothing more is needed here; #345's text could mention that body hides now reach that sequence too.
• The PR merges cleanly with current main (06303d8, which has moved about 30 commits past the PR's base). The merge adds no new refusable context-manager call and no removal site.

Minor

R1-1. hide's range form leaves a later stored copy of its end message in context, but reports that message as hidden.

• Where: src/framework.ts:6985 resolves each endpoint with findIndex, which returns the first stored copy. src/framework.ts:7027-7034 then widens only that copy to its body.
• What goes wrong: when the later endpoint's message was cut short and retried (partial body P, complete body R, both carrying the Discord id), hi stops at the end of P. refsIn still lists the Discord id in hiddenRefs, so the surface marks the message as hidden while R, its complete text, stays in the agent's context.
• Reproduced at this head: m1, m2, m3, then P(p0, p1) and R(r0, r1, r2) for d-cut, then after. hide d2..d-cut returns ok: true, hidden: 3 and leaves [m1, r0, r1, r2, after]. A following single hide d-cut removes R.
• Inconsistent with siblings: the single form takes every copy (7063-7077), and offline recovery's range form spans each endpoint from its first to its last stored copy (src/recovery/offline-branch.ts:448-454).
• Fix: resolve the earlier endpoint to its first match and the later endpoint to its last match, as offline recovery does, then widen with bodyRangeIn. Add the range case to the test "hide removes a message stored as a body whole, a one-shard body and every copy included".

R1-2. A conversation agent's maintenance isn't withdrawn while a surgery holds the store.

• Where: withdrawMaintenanceUnderSurgery() is only called inside withAuxiliaryAdmission (src/framework.ts:2836-2859). Persistent conversation agents get conversationAuxiliaryMembraneFor (2901-2909, wired at 9449), which checks refuseHeldProviderModel and then calls run().
• Why it matters: those agents are in this.agents (9516), so the pass ticks them. A conversation agent's tick that is running when the hold is taken can go on to make further provider calls (another recall-curve attempt, the carrier fallback, or a merge after a compression), and settleMaintenancePass() waits for each of them.
• Effect: there's no gate for such a call to park at, so this can't hang; it lengthens the operator call's wait. It also makes changelog.d/cm-0.14.changed.md's "Maintenance makes no provider call meanwhile" untrue for conversation agents.
• Fix: call this.withdrawMaintenanceUnderSurgery() in conversationAuxiliaryMembraneFor before run(), and add a test with a persistent conversation agent whose tick reaches complete after the hold is taken.

R1-3. previewAgentRuntimeSettings still documents the 0.13 contract.

• Where: its docstring says it "never throws for preview-layer reasons: … stale branch generation … come back as {available: false, reason}" (src/framework.ts:5297-5300). Under 0.14, previewRuntimeSettingsFor calls agent.planRuntimeSettings() and agent.getRuntimeSettings() (5316-5317) before runPreview's try.
• What actually happens: both reach getHotContextSettings, which context-manager 0.14 refuses while initialization is pending or failed. The method throws.
• What the PR does: it handles this at one call site, resume()'s own catch (4677-4696). Hosts calling the public method get the throw its docstring rules out.
• Fix, either of:
  • Move the catch into previewRuntimeSettingsFor and return {available: false, reason}. resume()'s catch then becomes a plain !preview.available case, and updateAgentRuntimeSettings's preflight keeps working the same way.
  • Correct the docstring to say a refusing manager throws, matching the PR's stated choice for the settings path.

R1-4. The 0.21.1 operator note describes context-manager 0.14.0's calibration load, but ^0.14.0 now installs 0.14.1.

• Where: CHANGELOG.md:701 says "an unstamped multiplier is kept and re-stamped". The note goes on to give a repair for two kinds of store.
• What changed in 0.14.1 (context-manager#179): a record without a stamp is now provisional, not re-stamped on load. It is discarded at a clamp edge, dropped to 1 when it puts a compile over budget, and replaced by the first accepted sample.
• Who still needs the repair: context-manager 0.14.1's own Operators bullet says the manual reset is needed only by a store that already opened on 0.14.0 and ran a committing compile.
• Effect: operators of 0.21.1/0.22.x reading this section can't tell whether their store needs the stopped-host repair. #365's fragment covers 0.14.1 for the next release only.
• Fix: one sentence in this note saying it applies to stores that ran a committing compile on 0.14.0, and that 0.14.1 handles a store that hasn't yet opened on 0.14.0.

R1-5. A lasting failure records a run every pass, so the history fills with copies of it within a few minutes.

• Where: each pass pushes a run with the failing agent's record (src/framework.ts:3475-3479). The history keeps 50 runs (3535-3536), and the default interval is 5 s (948).
• Effect: about four minutes into a lasting refusal, getContextMaintenanceSnapshot().history (and the maintain command's output) is 50 copies of that one failure. Older runs that did real work are pushed out. The alert dedupe added here already knows when a record is a repeat.
• Fix: don't push a run whose every record is a repeat that reportMaintenanceFailure suppressed. Alternatively, keep a repeat count on the newest such run.

R1-6 (exists on main too, but this PR makes the fix one line). stop() doesn't wait for an over-budget drain kick.

• Where: stopOwned awaits this.maintenancePass (src/framework.ts:2696-2698) and then syncs and closes the store. A drain kick (15732-15755) checks neither this.running nor anything stop waits on.
• What can happen: providerAdmissionClosed stops the kick's next provider call, but a compression already in flight can complete after the store is closed. Its result is then lost, logged as a drain failure.
• Why now: the kick was fire-and-forget on main too. Now that the PR tracks kicks in overBudgetDrains and gives surgeries and resume() settleMaintenancePass(), stop() is the one waiter left out.
• Fix: in stopOwned, await this.settleMaintenancePass() where it now awaits maintenancePass, and add this.running && to the kick's loop condition.

Outside this PR (a follow-up issue, not counted)

The Discord module's offline sync can't handle a message stored as a body:

• syncChannelHistory builds its map from queryMessages, which returns each shard. The map keeps the last shard per Discord id (src/modules/discord/index.ts:757-771).
• That shard's text never equals the full Discord text, so ctx.editMessage(lastShardId) runs (808-812), and context-manager refuses to edit a shard (message-store.ts:554-558).
• There is no try inside the loop, so that channel's sync aborts every time (687-694 logs it). Later offline messages aren't ingested, the delete sweep this PR now makes body-aware never runs for that channel, and lastReadMessageId doesn't advance.
• This needs adaptive resolution and a message over about 8k tokens (a large text attachment), and it predates this PR. It belongs to the same class as the removal fix: a single-message operation on a body.

Verified fine

• Context-manager API: continuesBody, bodyBoundsIn and BodyShard are exported by 0.14.0 and 0.14.1. removeMessage refuses any grouped message, and has since 0.10.0, so "since before 0.11" is true. In 0.14, removeRange refuses only a pairwise bisection (0.13 compared group ids).
• Removal sites: every remaining direct removal is body-aware: stored-removal.ts, the live suppression (8111-8113, via bodyGroupRun().group), module and Discord removal (15236-15243), the coalescer (10207-10217), rewinds (6589-6591), and the resumed suppression (16129). AF has no onMessage listener that depends on remove vs removeRange.
• Rewinds: shedNewestTurn's idx is always the end of a body, because shards share metadata and are appended synchronously. Taking the tool exchange in one removeRange is correct.
• Withdrawal and settling:
  • Context-manager makes provider calls only inside tick() (compression and merge) and resetHeadWindow, which AF never calls. AF ticks only in the pass and the drain kick, so the withdrawal only ever hits maintenance.
  • tick() awaits its compression (autobiographical.ts:4712-4718), so settling the pass covers the call in flight.
  • The withdrawal error is rethrown unchanged through compressChunkHierarchical while the branch hasn't moved, so instanceof MaintenanceWithdrawnError holds.
  • A gate waiter woken by a hold is withdrawn; one woken with the gate still closed parks again.
• Surgery hold: taking it is synchronous with the agent-idle check, release is idempotent and called from finally in all three operations, maintenanceTick() answers ran: false, and resume() checks before and after its waits.
• Alerting: the dedupe key matches opsAlert's (${agentName}:context-maintenance-failed), the reminder counts from the webhook's last post, and maintenanceFailureReported is pruned for departed agents at each pass.
• API server: the status endpoints don't call refusable context-manager methods. The branch getter reads the store while it's open, and branch.switch announces after the awaited move.
• Startup: ContextManager.open rethrows a failed initialization, so Agent's constructor never sees a refusing manager. AF never calls setStrategy.
• Offline recovery: the pairwise check carries previous across 1,000-message scan windows. A range spans each endpoint's first-to-last copies.
• Greptile's four findings at d71370d5 are fixed at this head: the parked call is withdrawn and re-parks; the reminder counts from the webhook's post; removeStoredMessage uses blob-free windows; the single hide's log is capped with capIds.
• Tests, run at this head on Node 22.21.0 with context-manager 0.14.1, each file in its own process:
  • The ten changed test files pass, 220/220.
  • The full suite passes 2179 of 2181. workspace-watcher "re-attaches after the root is removed and recreated" fails on this machine at the base cd036e0 as well. surgery-marks-receipt "a suppression with nothing addressable…" ("Suppression branch name must differ from the active branch") fails intermittently at the base too (1 of 3 runs there, 1 of 5 here). Neither file is touched by this PR.

Method

Two reviewers, each claim re-verified before adoption.

• Sol (Codex gpt-5.6-sol, xhigh, read-only sandbox, no network): about 21 minutes, 130 commands, 13.7M input tokens (13.3M cached), 50k output. It read the diff, the published 0.13.0/0.14.0/0.14.1 context-manager packages and their git tags, and Chronicle. Its sandbox couldn't create a store, so it ran only typecheck and one prebuilt test.
• Claude (Opus 5.5): checked upstream state with network access (npm dist-tags, tags, the related PRs and the release hold, a test merge with current main), swept src/ for refusable calls, and traced context-manager's history for legacy-store layout. It also ran the changed and full suites against an npm-resolved context-manager 0.14.1, compared failures against the base, and wrote a probe test for R1-1.
• Who found what:
  • Claude only: R1-1 (probe-confirmed), R1-4, R1-5, the Discord sync follow-up, the #345/#365 coupling check, and the test runs.
  • Sol only, verified before adoption: R1-2, R1-6 (confirmed fire-and-forget on main), and R1-3 (narrowed here to the docstring/contract).
  • Both: the API, removal-site and alert-key checks in "Verified fine".
• Sol findings not adopted:
  • Branch moves that don't re-initialize other managers: this is #326, which the PR defers to #353 explicitly.
  • Legacy bodies with the Discord id on only their first shard: no released context-manager writes such a store; every sharding release passes metadata to each shard, and the validators refuse rather than corrupt anyway.
  • Alert-cooldown keys surviving disposal: the map predates this PR, and the new map is pruned each pass.

Replying to this review.

#377 answers R1-1 to R1-6. Its description takes them one by one and names the test that covers each code fix. R1-4's fix is one sentence in CHANGELOG.md. We'll merge it no earlier than 2026-10-16 12:00 UTC, as its description says. Thank you for the review.
