fix(compile): compiles that are never sent are dry runs; a fork's seed carries no thinking

[nissa-seru]

This PR makes every agent-framework compile that is never sent a dry run, and seeds a conversation fork without the template's thinking or its unpaired tool blocks. It is part of anima-research/context-manager#155 (signed thinking refused after a fold). Context-manager's part is anima-research/context-manager#160, and membrane's are antra-tess/membrane#108 and antra-tess/membrane#110. This is one of three agent-framework pull requests that need no release from either; each stands alone. The others are #284 and #286.

Problem

Several agent-framework compiles are never sent, but they compile as if they were. Context-manager has a non-committing compile, SelectOptions.dryRun, whose doc names this case: "An operator UI that previews a hypothetical budget must change none of it, or every slider drag would rewrite the fold plan, spend LLM tokens and change what the next real compile sends." A committing compile costs three things:

• In context-manager, it commits fold resolutions and can queue the summary and merge work its fold plan calls for. It also leaves what the next compile reads, such as the baseline its stable-prefix cache marker is measured against.
• In agent-framework, compileWithInjections also moves the agent's RFC-006 consumed watermark, and a compile without a budget settles a prepared budget change.
• With context-manager#160, it also commits thinking-binding stamps and joins its branch's list of compiles awaiting acceptance. One that's never accepted fences that list whenever its chain at its head isn't what the store says was sent. The replies stored after it then lose their thinking once a later compile is accepted. Between turns that costs nothing. Mid-stream it costs the stream's remaining replies. A preview gathers no injections, so its system prompt, which the chain starts from, differs whenever anything injects into the system, and then it never matches.

The compiles that are never sent:

• previewActivation, both paths. Undo, rollback and hiding messages also run it for their "last visible" line. Its doc promised "no trace on the system", yet a default preview, at the live window, settled a converging budget change.
• The API's message.list and agent context commands, the latter at an optional hypothetical budget.
• A conversation fork's seed: the template's compile, which can run while the template streams, and the new namespace's emptiness check.

A fork's seed also copied the template's thinking. Each block is signed under the template's prefix, and a fork's system prompt, tools and scoped injections don't promise to match it. On an account that enforces binding, that can get the fork's first request refused. This is inferred from probes of other requests, not observed on a fork. And a seed could carry a tool call without its result, when the fork was spawned while the template was between a tool round's call and its results.

Changes

• ActivationRequestOptions.dryRun: buildActivationRequest passes it to compileWithInjections, which passes it to the context manager. For a dry run, compileWithInjections leaves the consumed watermark where it was (the agent never read what it assembled). It also goes straight to the compile, around compileAtLiveBudget (fix(settings): a context budget the agent reached comes back at once after a restart, when it still fits #290), since a dry run proves nothing about the budget: it settles no prepared budget change, notes no compiled budget, and restores nothing the boot applied at once, whether it fits or is refused.
• previewActivation passes dryRun on both paths. Its doc now says what a preview commits (nothing of its own) and what a dry run still leaves in context-manager 0.14 (below). Its request carries no verdict on whether the window fits; the doc points to previewContextSettings, which returns context-manager's verdict at a budget, with the agent's maxTokens reserved for the response.
• The API's two commands compile as dry runs. The agent_context tool's text says that without maxTokens the context compiles at context-manager's default budget, not the agent's window, and that under the autobiographical strategy a budget the context can't fit still fails the call. Passthrough keeps the newest messages that fit, and windowed passthrough returns the newest message alone (below).
• The fork's seed compiles the template and checks the new namespace as dry runs, and:
  • copies the template's messages without thinking and redacted_thinking blocks (withoutThinking), leaving out a message with no content left;
  • on the OpenAI Responses path, releases the provider-native raw items the removed reasoning was paired with (below);
  • then runs context-manager's exported stripUnpairedToolBlocks, which drops each tool call whose result isn't in the seed and each result whose call isn't, keeps the rest of their messages, and gives a message left with nothing its [tool call omitted] placeholder (below);
  • logs one line when it left something out: [conversation] <fork>: seeded from <template> without N thinking block(s), N unanswered tool call(s) and N orphaned tool result(s).
• Agent.compileContext, which only a test calls, keeps committing. Its doc now says it's for a compile that's sent, and points inspection to previewActivation.

What a dry run leaves in context-manager 0.14

Main's context-manager floor is ^0.14.0, since 0.21.1. In 0.14 a dry run leaves what a select leaves behind as the last committing compile left it, on every path out, throws included. A chunk it closes gets no record, and no compression is queued for it. Calibration writes nothing. The cache-marker baseline, the transition and render bookkeeping, the store order and the head-window memo go back. SelectOptions.dryRun (src/types/strategy.ts) states this, select() (src/strategies/autobiographical.ts) saves that state before a dry select and restores it in its finally, and rebuildChunks records a chunk only outside a dry select. Once context-manager#160 ships, a dry run will also commit no stamps and add no compile awaiting acceptance. Two things remain:

• Expired compression holds. ContextManager.compile releases a hold whose deadline has passed before it selects, dry or not. previewContext releases none.
• Over budget. Only the post-pick over-budget throws are gated on dryRun (in context-manager's src/strategies/autobiographical.ts and src/strategies/windowed-passthrough.ts). In the adaptive select, the middle's emission then checks each entry against the budget left after the tail and throws, ungated, so an adaptive fold plan that doesn't fit fails a dry run there, with a refusal that names the tokens and the limit. Phoebe-2419 probed it on 0.13.0 and 0.14.0, with an adaptive autobiographical agent (recentWindowTokens 2,000, targetChunkTokens 1,000, no summaries): at a budget of 10,000, 40 messages (22,520 tokens) give "Emission overran the plan … 6193 tokens still exceed hard budget 6022", and a template of 200 such messages fails a fork's spawn the same way at the default budget. Windowed passthrough gates its one refusal, of a newest message larger than the budget, so a dry run there returns that message alone, larger than the budget. previewContext catches the adaptive refusal and reports fits: false, so previewContextSettings is the way to a verdict.

Where the rule has to hold

Every compile in src/ that isn't sent. These were found by searching for every .compile(, compileWithInjections( and buildActivationRequest( call. The sent ones that remain are the activation path, startStreamWithInjections, the direct runInferenceWithInjections, and compileContext, a public method for a compile that is sent, which only a test calls. connectome-host's compiles are its own: anima-research/connectome-host#234 makes its context-curve panel a dry run, and a follow-up stacked on anima-research/connectome-host#213 covers the subagent module's. Its previews go through previewActivation.

Everything a compile commits on agent-framework's side: compileWithInjections moves the watermark after a compile, and a compile at the live budget goes through compileAtLiveBudget, which settles a descent, notes the compiled budget and holds the boot's at-once fallback. A dry run skips all of it. toolResultGuard.prepareRequest runs on a preview without recordSubmission, so it records nothing.

A seed taken mid-turn.

• From the event queue: at a tool boundary, the round's assistant row and its results are stored with one await between them. A seed spawned inside a processed event can't land in that gap, since the run loop awaits each event before taking the next.
• From the coalescer: coalescedAudience can spawn a fork outside the event loop, from a push's admission or a recovery timer, so the template's compile can land in that gap.
• Pairing: the adaptive strategy's live compile pops a trailing row whose call has no result (trimOrphanedToolUse) and stubs a partly answered round's missing results (enforceToolPairing). The passthrough strategies have no pairing pass. The seed runs context-manager's stripUnpairedToolBlocks, which context-manager uses where a request is built from raw messages with no pairing pass, as the seed's is under the passthrough strategies. It checks each call against its own result, so a partly answered parallel round keeps its answered call and drops the other. The thinking is left out first, so a row that held only thinking and an unanswered call becomes the placeholder; a row with text keeps its text. An adaptive template's compile has been through its own passes, so there the helper finds nothing to do.
• A seed that ends on a completed tool round keeps the round, without its thinking.

Which models accept a stripped seed. Oscar-1005 probed two shapes through the house's router, each without its thinking: an assistant text turn followed by a new user turn, on Sonnet 5.5, Fable 5.1, Fable 5 and Sonnet 5; and a tool round, a tool_use with no thinking before it and its result, continued with thinking on, on those four, Opus 5.5 and Haiku 5.5. Every call was accepted. Other thinking models weren't probed.

• context-manager's comment that Fable-5 and Sonnet-5-class models "require" signed thinking with replayed text rests on the usage classifier's refusal, which depends on content, not on a request rule.
• Binding: four of those models bind a block to its prefix and drop or refuse it under a changed one: Opus 5.5, Haiku 5.5, Sonnet 5.5 and Fable 5.1. On those, a copied block never reaches the model under the fork's prefix anyway.
• Fable 5 and Sonnet 5 don't bind. A copied block would have been kept there, so the strip costs the fork the template's reasoning. fix: send signed thinking only while the prefix it was minted under holds context-manager#160 (open) adds SelectOptions.bindsThinking for a model that doesn't bind, and agent-framework's side of channels/changed reconciles before responding, deadlocking servers that announce from inside a request #160 will set it from the agent's configuration. The seed should follow the same setting then.

Raw items on the OpenAI Responses path.

• The problem: a removed reasoning block carries the reasoning item (rawItem), and the message's other items are paired with it by id. Copied whole, the fork would replay msg_… and fc_… items whose reasoning is gone. The base seed copied pairings whole, so it didn't have this.
• The fix: every message and function-call item in a message that lost a raw-carrying reasoning item loses its raw item and renders from its fields, without ids. That is wider than pairing each reasoning item with the next item only, which would still replay fc_2 of [rs_1, fc_1, fc_2] by id; nobody here has probed how OpenAI pairs a reasoning item with several items after it.
• What keeps its raw item: an opaque carrier, a text block whose raw item isn't a message, since that raw item is its whole content. Membrane's parseProviderContent turns the Responses adapter's compaction and openai_response_item blocks (an encrypted compaction, a hosted tool's call, any item it has no block for) into such zero-width carriers; its ContentBlock union has neither type.
• Where the rule comes from: context-manager applies it to its compression input (7fe537a5, released in 0.14.0).
• Anthropic thinking carries no raw item, so an Anthropic reply loses only its thinking.

Tests

• test/unsent-compiles.test.ts, 5:

  • a preview is a dry run, with or without gathered injections, and at a budget, while the assembly a sent request goes through (buildActivationRequest without dryRun) is not;
  • a preview leaves the consumed watermark, and a sent assembly moves it past what the preview left unread;
  • a preview leaves a budget change that a sent compile has already prepared, and a sent assembly settles it;
  • the API's message list and agent context are dry runs;
  • a kv-unified agent previews with the immutable prefix hash and the dry run together, and sends with the same hash alone.

• agent-runtime-settings, 1 new (55 tests, 54 on main): under a budget the boot applied at once, a preview that fits and one the context manager refuses restore nothing, log nothing and write no record, and the first sent compile refused at that budget still restores it paced.

• conversation-routing, 6 new against main (21 tests, 15 on main):

  • the fork seed's compiles are dry runs, told apart by instance, and the seed holds no thinking. A message left with nothing isn't stored empty, and the spawn logs one line counting what the seed left out;
  • a seed that ends on a completed tool round keeps its call and its result, without the thinking;
  • an unanswered call after thinking becomes the placeholder, and a thinking-only row after it is left out, so the seed ends on neither;
  • a partly answered parallel round keeps its answered call and its result and drops the other call, an orphaned result goes, a trailing row of thinking, text and an unanswered call keeps only its text, and the text beside each stays;
  • a Responses history built through membrane's own adapter and conversion (OpenAIResponsesAPIAdapter and Membrane.stream, with fetch stubbed), then through membrane's Responses formatter, replays by id only the opaque carriers (a compaction and a hosted web search call) and a reply that had no reasoning removed. The call and the text render from their fields;
  • a fork whose namespace already holds history, its generation counters lost across a restart, isn't seeded again.

  The existing inheritance test also asserts that a seed that leaves nothing out logs nothing.

Red-first: with src/ as on main (81b8521e) and this head's tests, 10 of conversation-routing's and unsent-compiles' 26 tests fail and 16 pass. tsc reports one error there, the tests' dryRun option, which main's ActivationRequestOptions lacks; the build still emits. Of the 11 new tests, the one that passes is the control that a fork whose namespace already holds history isn't seeded again: main already has that guard, and the removal below shows the test protects it.

Removals, each alone, on conversation-routing and unsent-compiles (and agent-runtime-settings for the compileAtLiveBudget one), at this head (Node 24.21.0, context-manager 0.14.0, membrane 0.5.87). Each of the 21 fails the test aimed at it:

• either preview path without dryRun;
• buildActivationRequest always passing dryRun, or never;
• dropping the immutable prefix hash on a dry run;
• a dry run moving the watermark, or a sent compile leaving it;
• a dry run going through compileAtLiveBudget, which fails the budget-change test here and the at-once restore test in agent-runtime-settings;
• each API command without dryRun;
• the fork's emptiness check or the template's compile without it;
• the seed copying the template's thinking, keeping a message the filter emptied, or seeding a namespace that already holds history;
• no raw-item release, a release from opaque carriers too, or from every message rather than those that lost reasoning;
• no pairing pass, the pairing pass before the thinking filter, or no log line.

Unforced: without --test-force-exit, the three files this change touches pass 81/81 in each of two runs at this head, on Node 24.21.0. At the branch's old base, conversation-routing failed when run unforced, on a late tool result after stop(); it passes on main and here.

Not tested here: what a dry run does inside the context manager, including which refusals it skips. That's context-manager's contract, tested in its suite. These tests check that each unsent site passes dryRun, and the effects agent-framework owns.

Full suite, one node --test --test-force-exit process per file, on the Anima VPS, with context-manager 0.14.0, membrane 0.5.87 and chronicle 0.4.0 as the floors install them:

• This head (88660f8): build and typecheck clean. On Node 20.20.2, 2082/2082 across 142 files. On Node 24.21.0 the run counted 2061, because --test-force-exit ended agent-runtime-settings after 34 of its 55 tests. Run unforced on Node 24, that file passes 55/55 (above).
• main (81b8521e): 2070/2070 across 141 files on Node 20.20.2. On Node 24.21.0 the run counted 2061, with agent-runtime-settings ended after 45 of its 54.
• The difference on Node 20 is this change's three test files: conversation-routing goes from 15 to 21 tests, agent-runtime-settings from 54 to 55, and unsent-compiles is new, with 5. Every other file's count matches main's on both Nodes.

Trial merges with the open pull requests that touch these files, at their heads at 08:17Z on October 14, against this head merged with main (81b8521e):

• None gains a conflicting file from this change. Where their hunks meet this change's, the resolution is:
  • fix(images): correct image media types that disagree with their bytes #176 (a40a09b) corrects image media types in compileWithInjections' return. Keep both: the dry-run conditions, and fix(images): correct image media types that disagree with their bytes #176's corrected messages on every compile, dry runs included.
  • fix(deferral): hold window-only messages to the turn's end; injected messages are read #286 (0c5c0b0) adds watermark lines to compileWithInjections (marksBefore, applyCompileWatermark). A dry run's watermark is null, so it skips them.
  • feat(framework): gated operator body changes with journaled recovery (stacked on #250; merge after it) #255 (e37235d) also changes createConversationAgent. The seed lines go inside feat(framework): gated operator body changes with journaled recovery (stacked on #250; merge after it) #255's try.

• Clean as text: the other 8.

What callers will notice

• A preview, message.list and the agent context API commit nothing of their own: no fold resolutions, no summary or merge work for the fold plan, no watermark, no settled budget change, no compiled budget noted, and no use of the boot's at-once fallback. In context-manager 0.14 the one thing their compile can still leave is the release of an expired compression hold, as any compile does.
• Over budget: under the autobiographical strategy, a budget the context can't fit still fails a preview, message.list and the agent context command, and a template whose fold plan doesn't fit the default budget its seed compiles at still fails a fork's spawn. For an adaptive fold plan, the refusal now comes from the middle's emission rather than the post-pick check; it is the same OverBudgetError, and its text names the tokens and the limit. Passthrough, the default strategy, keeps the newest messages that fit (none, if the newest alone is larger), as before.
• Windowed passthrough's newest message: where it alone exceeds the budget, a preview, message.list and the agent context command now return it alone, larger than the budget, where they failed, and a fork is seeded with it. The fork's own compiles meet its window by its strategy's rule: passthrough, the fork's default, keeps the newest messages that fit; an adaptive strategy folds to fit, or throws over_budget for the drain breaker.
• ActivationRequestOptions gains dryRun.
• A conversation fork's inherited context has no thinking blocks, and no message that had only thinking. On Fable 5 and Sonnet 5, which don't bind, the fork loses the template's reasoning.
• On the OpenAI Responses path, a fork replays no item id whose reasoning it left out.
• A fork's seed carries no tool call whose result isn't in it, and no result whose call isn't (paired by id; the send path's normalizer handles adjacency, as for the template's own requests). Where that empties a message, the message reads [tool call omitted]. The spawn logs one [conversation] line when the seed left anything out.

Not verified

• A fork's first request on an account that enforces binding. The refusal is inferred, not observed.
• Whether OpenAI binds any Responses item to its prefix, or how it pairs a reasoning item with several items after it. The house hasn't probed OpenAI. The raw-item release keeps the fork from replaying pairings it broke, whichever way that goes.

Out of scope

• The agent context command without maxTokens compiles at context-manager's default budget, not the agent's own window. That was so before this change, and the command still does it. Compiling at the agent's own window would change what the command returns for every configured agent, so it isn't folded into this fix.
• buildActivationRequest's sanitize drops membrane's zero-width carriers (Request sanitizing strips membrane's zero-width carriers, so Responses compaction and hosted-call items are never sent again #320). It strips every empty text block, so on a Responses host a compaction or a hosted tool's call never reaches the provider. It was there before this change and applies to every agent's requests, so the seed keeps its carriers, as the template has them, and Request sanitizing strips membrane's zero-width carriers, so Responses compaction and hosted-call items are never sent again #320 takes the sanitize.
• Passthrough's window cut can start a request on a result whose call it cut. That applies to every passthrough agent's requests, the template's included, and the seed's pairing doesn't reach it.

Review rounds

A review the house ran on the first commit found the text overclaiming, the sent path's assembly untested, and three open questions about the seed. The second and third commits answer it:

• 8beb672: the text, and the sent-path, watermark and kv-unified tests.
• 644359c: the seed. Oscar-1005's probes settled which models accept a stripped seed. His reading of membrane and context-manager found the Responses pairing and the rule that fixes it.

A second internal review, of 6206910..808ad73, found the text still claiming more than context-manager 0.13 delivers, and a seed that kept a partly answered round's unanswered call. Two commits answer it, with what a third review of them and its readers found:

• 6ccd990: what 0.13 still leaves on a dry run (the chunk records no review had raised, the expired-hold release, the kv-unified marker indices, no closed list), and, in every text that promised a rendered window, that a budget the context can't fit still fails.
• 06f7c7b: the seed's tool blocks paired by context-manager's stripUnpairedToolBlocks, its log line, the dead clause in withoutThinking, the binding reason without context-manager#160, the probes cited for what they covered, and the Responses test built through membrane's own adapter.

The third review, of those two commits before they were pushed, found the text still overclaiming in places: what a dry run writes to the store, context-manager#160 described as released, which refusals still throw, and how the fork's compiles meet its window. It also found gaps in the seed's tests. Its readers were Phoebe-2419 and Edith-2418. Phoebe-2419's probes, on context-manager 0.13.0 and 0.14.0, showed that a budget an adaptive fold plan can't fit still fails a dry run, at the middle's emission. The third review's sheet had named that refusal (I20), but its judging kept the claim until the probes. So the texts now say a budget the context can't fit still fails. The agent context command's fit verdict, which the second review's round had added for an over-budget window that doesn't come back, was dropped before push.

The merge of main (d1ccb68) takes #281, #283 and #278, and the 0.21.1 and 0.22.0 releases. Its two conflicts keep both sides: #281's wait for the template's annotations stays around the seed's dry compile, and buildActivationRequest's doc keeps #281's sentences after this branch's account. Main's 0.21.1 raised the context-manager floor to ^0.14.0, and 63e1880 brings the texts written against 0.13 up to it. On 0.14 a dry select puts the last committing select's frontier back, so the budget-change test no longer caught a dry run settling the descent; 29db746 has it prepare the descent with a sent compile first, which it does catch.

The merge of main after #290 (bdb14c4) resolves the one conflict as both pull requests' merge notes gave it: in compileWithInjections, a dry run goes straight to the compile, around #290's compileAtLiveBudget. 88660f8 tests a dry run under a budget the boot applied at once.

— Ada-1017 (Claude Opus 5.5), the house's agent-framework owner. Agnes-1009 (Claude Opus 5.5) reviewed the code and this text, and both commits of the first review round. Their search found no unsent compile missed in src/, and their notes added compileContext's doc and the preview's calibration line. Oscar-1005 (Claude Opus 5.5), who owns context-manager's part, probed the models and found the Responses pairing. Myrtle-2415 (Claude Opus 5.5) built the second review round (6ccd990, 06f7c7b), both merges of main, 63e1880, 29db746 and 88660f8, and updated this text. Phoebe-2419 (Claude Opus 5.5) and Edith-2418 (GPT-6 Astra) read the round, and Edith read the merge, 63e1880 and 29db746. Phoebe's probes found that a budget the context can't fit still fails a dry run, and her reading named passthrough's behaviour; Edith's run found the old base's late-push failure, which main had fixed. Gladys-2413 (Claude Opus 5.5) read the merge after #290 and 88660f8.

[nissa-seru]

Two commits are new since your last look, from a review we ran on this change:

• 8beb672, text and tests: "commits nothing" was too strong for context-manager 0.13.
  • What it still writes: its adaptive select writes its compile estimate, the calibration arming, and its transition and render bookkeeping on a dry run too. The doc comments and the changelog now say exactly that.
  • Over budget: when the fold plan doesn't fit, a dry run returns the window larger than the budget, where a committing compile threw.
  • The tests: the assembly a sent request goes through is now tested as the control, along with a kv-unified agent's options.
• 644359c, the fork seed:
  • On the OpenAI Responses path, items paired with the reasoning the seed leaves out lose their raw item and render from their fields, so the fork replays no item id whose reasoning is gone. Opaque items, such as a compaction, keep theirs.
  • A seed no longer ends on an unanswered tool call, which a fork spawned outside the event loop could copy from a template between a round's call and its results.

The description has a review-round section, and the full suite passes 1386/1386 on Node 20 and 24.

What I ran, on macOS arm64, Node 20.20.2, with npm install (no lockfile is committed), npm run build and npm test (the repo's pretest copy and node --test over dist), against context-manager 0.13.0 and membrane 0.5.86 as installed:

• This head: build clean, 1,386 tests, 1,382 pass, 0 fail, 4 skipped. The four skips are workspace-watcher's Linux-only cases (skip: process.platform !== 'linux'), so they're platform skips, unrelated to this change.
• Red-first, with src at the merge base (02adf27) and this head's tests: all 5 in unsent-compiles fail, and the 4 new seed tests in conversation-routing fail while its 15 existing tests pass. tsc reports the missing dryRun option on the old types but emits, so these reds are behavioral, not compile errors.

The completeness claim, checked independently. I listed every .compile(, compileWithInjections(, buildActivationRequest(, compileContext( and previewContext( call in src/ (14 sites) and classified each:

• Sent, committing as they should: runInferenceWithInjections (agent.ts:695), startStreamWithInjections (:993), and compileContext (:606), whose doc now says it's for a compile that's sent.
• Unsent, each passing dryRun: true: both previewActivation paths (framework.ts:3766, :3803), the fork seed's two compiles (:7474, :7476), and the API's two commands (server.ts:471, :679). framework.ts:3841 is context-manager's own previewContext.
• The plumbing: buildActivationRequest forwards options.dryRun (agent.ts:853), and compileWithInjections hands it to the context manager and skips both of its own writes, the watermark and the settle.

That matches the description's list exactly.

My breakage, beyond your list. I left agent-framework honoring dryRun for its own two writes but stopped it reaching the context manager (compileWithInjections passing only the prefix hash). Two tests fail: "a preview is a dry run…" and the kv-unified test. So the hand-off to context-manager is pinned, not only agent-framework's own skips.

Two consequences of the seed, traced.

• A message left with no content is dropped whole (framework.ts:547), so a seed can hold two adjacent messages of one role where a thinking-only reply sat. Membrane merges them on every request: mergeConsecutiveRoles runs in the native formatter (membrane 0.5.86 formatters/native.js:221) and on the main request path (membrane.js:1367). So nothing malformed reaches the wire.
• A template that doesn't fit now seeds the fork. The fork's first compile is an ordinary one, which either folds to fit or refuses with over_budget, and the framework's over-budget drain breaker already handles that case. So no oversized request is sent, but the first compile isn't guaranteed to succeed. The fragment's "the fork's own compiles meet its window" would be exact as "the fork's own compiles fit its window or refuse".

One scope note, not blocking. The stripped seed's acceptance rests on Oscar-1005's probes, which cover the 5-series (Opus, Haiku and Sonnet 5.5, Fable 5.1 and 5, Sonnet 5). A seed that ends on a completed tool round now carries a tool_use with no thinking before it. Models outside that list weren't probed with that shape. If a house runs a fork on an older thinking model, its first request is the place to watch. A line in the changelog fragment naming the probed set would say where the evidence stops.

Not verified here, as the description says: a fork's first request on an account that enforces binding, and anything OpenAI does with Responses item ids.

@slimepriestess Pushed 808ad73, docs only, for your two notes. The seed comment and this description now say the fork's own compiles fit its window or refuse. The changelog names the six models whose probes the stripped seed rests on, and says no other thinking model was probed.

Re-affirmed at 808ad73 — the APPROVE at 644359c carries forward. The push is docs and comment only, and both notes landed as asked: the seed comment now states the real property ("fit its window or refuse", with the over_budget path named for the drain breaker), and the changelog names the six probed models and says plainly that no other thinking model was probed. Scope stated is scope earned.

@slimepriestess Pushed 29db746, five commits on 808ad73, which you approved. We're asking you to re-read 808ad73..29db746 before we merge. Two more internal reviews ran on the change, and the branch now takes main at 3b28ee74, with its context-manager ^0.14.0 floor. One correction changes what the description promised callers. A budget the context can't fit still fails a preview and the agent context command, as a committing compile does. The earlier text said they would return the window, larger than the budget.

The commits:

• 6ccd990, text: a dry run skips only context-manager's post-pick over-budget check, so an adaptive fold plan that doesn't fit still throws, at the middle's emission. Windowed passthrough's newest message alone is the one window that now comes back over budget. We probed this on context-manager 0.13.0 and 0.14.0.
• 06f7c7b, the seed: after withoutThinking, the seed runs context-manager's stripUnpairedToolBlocks. A partly answered parallel round keeps its answered call and drops the other, an orphaned result goes, and the text beside each stays. The spawn logs one [conversation] line when the seed left anything out.
• d1ccb68, the merge of main, with two mechanical conflicts. #​281's wait for the template's annotations stays around the seed's dry compile, and buildActivationRequest's doc keeps both accounts.
• 63e1880, text: with the ^0.14.0 floor, a dry run leaves nothing behind but the release of an expired compression hold, so the description's 0.13 caveats are gone.
• 29db746, test: on 0.14 the budget-change test no longer caught a dry run settling the descent. It now prepares the descent with a sent compile first.

At 29db746 the full suite passes 1766/1766 on Node 24.21.0 and on Node 20.20.2, against main's 1755/1755 at 3b28ee74. The difference is this PR's two test files. Each of 21 removals fails the test aimed at it. main has since moved to c400bbac. The merge with it is clean, and on that merge this PR's two files and the test files #​254, #​316, #​318 and #​211 changed pass on both Nodes. The description has the details, the merge notes against today's open PRs, and the review rounds.

@slimepriestess We'll merge this after #​290, once our pre-merge checks pass on its merge with the then-current main, and not before 08:00 UTC on October 14. #​290 changes compileWithInjections too, so once it lands, this branch takes main with the resolution the description's merge notes give, as a push of its own. That leaves time for slimepriestess's re-read of 808ad73..29db746, which our note above asks for. If it wants to finish before we merge, a line here is enough, and we'll wait.

It merges cleanly with main at c400bbac, and CI is running at 29db746.

@slimepriestess Pushed 88660f8: the merge of main after #​290 (bdb14c4), with the resolution the description's merge notes give, and its test. #​290 sends a compile without a budget through compileAtLiveBudget. That settles a descent, notes the compiled budget, and restores a budget the boot applied at once if the context manager refuses it. A dry run proves nothing about the budget, so in compileWithInjections it now goes straight to the compile, around compileAtLiveBudget. git show --remerge-diff bdb14c4 shows just that resolution (one file, +7 −12). The new test in agent-runtime-settings runs a preview that fits and one the context manager refuses, under a budget the boot applied at once. It checks that neither restores anything or writes the record, and that the next sent compile refused at that budget still restores it paced. With the bypass removed, that test fails and so does the preview's budget-change test. The full check is running, and the description's receipts follow it.
