@slimepriestess @antra-tess, we're asking you to review this pull request before we merge it. It changes what compile() sends for any host that passes the new option.

Problem

Some Claude models bind each signed thinking block to the request it was minted in (#155). On an account that enforces the binding, a request that carries a block after anything before it changed is refused with a 400 ("Invalid signature in thinking block. The block is bound to a different conversation…"). With the provider's drop control, the block is set aside instead. A compile changes what comes before a stored reply all the time: a fold, an edit, an injection that moves to the newest user message, a tool or system text change. So on such an account, by our runs, a long-running agent whose replies carry thinking is refused from its first fold, and from its second turn when an afterUser injection moves each turn. Nothing in context-manager knows which blocks a request can still take.

This replaces #160, which kept a stamp per reply and inferred which compile each answered. This one compares each compile with what its branch last sent, and the host, which knows what each request carried and which reply answered it, notes the rows its stream sent after the compile.

Changes

• SelectOptions.thinkingBinding: { binds, dropBlock, participant } and SelectOptions.identity: { system, tools, model, request }. participant is the name the model's own replies are stored under. identity holds opaque digests the host passes of what the request carries before its messages: the system text as sent (system-position injections included), the tools in sent order, the model, and the rest (tool choice, thinking config, output limit). With binds, both are required, and a compile without them, or with a digest that isn't a string, is refused before anything is selected.

• The record: per branch, in the manager's namespace, a Chronicle snapshot state (<namespace>/thinking-binding) of what the branch last sent:

  • a 66-bit digest of each message its last committing compile with binds sent (participant and content in canonical key order, injections included, cache markers aside);
  • for each row a host noted after them, a digest of each message the compile makes of it (a bundled tool cycle makes several): what its stream's requests went on to carry, and at the stream's end its last reply;
  • the stored bodies the compile sent without their thinking;
  • the compile's head digests;
  • the branch's sequence where the record began.

  Being a branch-scoped state, it survives a restart, and a branch made from another starts from the parent's record as of its branch point.

• ContextManager.noteRequestSent(rows, identity, compileId): a host calls it as it sends each later round of a stream built from a binding compile, and once more at the stream's end, on that compile's branch, with that compile's provenance.compileId. A note whose id isn't the compile that wrote the branch's record writes nothing and returns false, so a note that arrives after another committing compile vouches for nothing. rows are everything the stream's requests carried after the compiled messages, every round so far, and at the end its last reply, in order: the id of each stored message, or { unstored: true } for one the host can't vouch was carried or returned as stored. Each stored row is digested as renderAsNewest renders it, which is what a host is told the next compile renders, and as the compile turns that into messages: a tool result stored under another participant goes as the user's, and a bundled tool cycle as each of its parts; with no renderAsNewest, a body stored as shards is unvouched. An id the store no longer holds, as after a removal, vouches for nothing, as the marker does. A request-only row the host puts back in the same place at every later request needs no row. A note with another head than the record's leaves the record vouching for nothing until the next committing compile; a compile under the new head reports the head change, and one under the record's own head reports 'messages'. On a branch with no record, or one it can't read (which it logs), a note writes nothing and returns false.

• The comparison:

  • From the first message that differs from the record, or from the first message when a head digest differs, every message goes without its thinking.
  • Past the record's end nothing keeps its thinking: only the host knows which stored reply answered which request. So an edit, a removal by any manager, a shard, or another writer's message shows as a difference from the noted rows.
  • A reply sent without its thinking stays without it while it renders, since what came after it was minted without it.
  • Only the participant's own replies keep thinking. Another agent's reply in a shared slot or an auxiliary view, a summary's recall answer, and an injection never do.

• A host that passes thinkingBinding and doesn't call noteRequestSent loses each reply's thinking at the compile after it's stored, once the branch has a record, and is never refused for it. So a host notes every turn at its end, a single-round one included.

• Replies from before the record: without dropBlock, a reply stored at or before the sequence where the branch's record began never keeps its thinking. So a branch's first compile without the drop control leaves out every reply's thinking once. With the control, those replies are left for the provider to judge. Either way the record starts.

• Without binds, a compile is as before: it neither reads nor writes the branch's record. A record an earlier binding compile left is compared at the next binding compile like any other: a message keeps its thinking only while everything up to it matches what that compile sent and its stream noted, a prefix the provider took with that thinking, and nothing past the record's end keeps it. So a stream's notes still write after a compile without binds. A dry compile reports what it would leave out and writes no record.

• A record the store can't read or write is logged and never fails a compile or a note. One that can't be read is read as none, under the first-compile rule, and a committing compile writes its own in its place, as for a record this version doesn't read. A compile whose record can't be written leaves the one before, if any, which its stream's notes can't extend, so what it sends past that record goes without its thinking. A note that can't be written is lost, and the rows it would have added go without their thinking unless a later note of the stream writes.

• CompileResult.thinkingStrip: { newly, cause, changed? }: set when a compile newly leaves out a reply's thinking against the compile that wrote the branch's record, sent or not, with the bodies and 'head' (with the digests that changed), 'first' or 'messages'. CompileResult.thinkingRecordedAfter: on every binding compile, the branch's sequence when its record began, or, on a branch with no record, where the first would begin. A reply at or below it was stored before the record, so a provider drop of its thinking isn't a strip that missed. That's what a host's alert can tell expected drops from incidents by.

• Provenance: a body sent without its thinking reads as incomplete (missing: ['content']), and the rendered layout prices what was sent: each entry's thinking as the compile sent it, part by part for a bundled tool cycle the compile splits.

• Calibration: ContextStrategy.noteThinkingLeftOut(blocks) hands the strategy the stored thinking a committing compile with binds left out. AutobiographicalStrategy takes its price off the calibration sample's estimate, so the sample compares the provider's count with what was sent. A strategy that throws there is logged, and the compile stands.

• Carriers: on a binding compile, AutobiographicalStrategy renders and prices a summary's carriers as under carrierPolicy: 'live-strip', since a carrier was minted in its summarizer's request and a binding model never takes it in the live window. Without this, the compile would still leave them out (no stored body), but the plan would have priced them, and a carrier-only answer would lose its prose fallback. Each select prices them by its own option, so previewContext takes thinkingBinding too, and a preview without it prices them as configured.

• Moved, not changed: canonicalJson moves to src/canonical-json.ts, and the strategy's stripThinkingBlocks is now the shared withoutThinking.

A caller's part: while one of a branch's requests is still streaming, compile for that branch with binds only with dryRun. A committing compile with binds there makes the stream's later notes vouch for nothing, so its replies go without their thinking; a dry compile writes no record and leaves the notes as they were. By reading, agent-framework compiles committing only at a stream's start, under the agent's turn lock, and connectome-host's committing compiles are launch checks on a fresh sub-agent's own manager. The comparison is of compile output: a host that turns compile output into a request (sanitizing it, adding rows) must do so the same way at every request, and note a row only where the next request will carry it as the stream sent or got it.

Companion work: anima-research/agent-framework#768, merged, sends the provider's drop control. No host passes binds yet. This PR changes nothing until one does, apart from the record's state being registered at open, so it's safe to land first.

Tests

npm test at this head: 2913 pass / 0 fail. main at 8db49e6: 2853 pass / 0 fail.

• test/thinking-binding.test.ts, 60 tests, covering:
  • with and without the option, and the first record with and without the drop control;
  • a record begun under the control, then a compile without it;
  • a noted reply, and a moved injection;
  • oldest messages leaving the window, without the control too;
  • a stream's replies with every note, with the rounds' notes only, and with none;
  • a single-round turn noted and not, as when a host stops before its note;
  • a write between rounds the stream didn't send, in the agent's slot and in an auxiliary one;
  • an edit to a noted row and to the noted last reply, a noted row removed by this manager, another on the shared slot, or mid-stream, a filtered row, and a row rendered with an addition;
  • a row noted as unstored, rows renderAsNewest renders otherwise or as null, and a sharded row with no renderAsNewest;
  • a noted result stored under another participant, and a noted bundled tool cycle;
  • notes that carry every round so far, and a note of the latest round alone;
  • a note for a stream after another committing compile with binds, after one without, and after a dry compile, a later note of the same stream, and a note with another compile's id;
  • a compile whose record the store can't write, with a record before it;
  • a note sent with another head, alone or followed by one under the record's head, compiled under either, and a window that starts at the noted reply;
  • a reply long enough to shard, not noted;
  • noteRequestSent on a branch with no record or a malformed one, its refusals, and an id the store doesn't hold;
  • a strategy that throws taking note of the thinking left out, and a store that can't read or write the record, at a compile and at a note;
  • a compile without binds on a branch with no record, which writes none;
  • a shorter or empty record;
  • each head digest changing;
  • every refusal, before any select and leaving an existing record;
  • a compile without binds that neither reads nor writes the record, and a binding compile after it, compared against the earlier record;
  • a reply reported again after a compile that didn't send it;
  • another participant's reply;
  • a restart, branchAt() and fork(), and a branch's write isolation;
  • a dry compile;
  • malformed records and a control;
  • provenance and layout, a sharded reply's shards included, kept replies beside a summary's and an injection's thinking, and a split body whose second part goes without;
  • a compile failing after its select, with and without binds;
  • the strategy's note at each committing compile;
  • calibration;
  • the record's sequence;
  • two namespaces on one store;
  • carriers rendered and priced as under live-strip, by each select's own option: a dry compile with and without it, previewContext with and without it, and a recall pair's price inside each select;
  • unit tests of the comparison, past the record's end, cause precedence, markThinkingLeftOut and the digest, cache markers aside.
• Removals: 73 pieces of this change, each broken once in turn, and each fails a test.
• Failing first: six streams an earlier round of this change got wrong (a write between rounds in the agent's slot and in an auxiliary one, an edit, a removal, a filtered row, a strategy's addition). Run against that earlier round, all six kept the reply's stale thinking; at this head each leaves it out. And a note for a stream after another committing compile: run against the round before the compile id, the reply minted under the earlier compile kept its thinking at the next one; at this head it goes without. And the automated review's finding on this PR's first head, e06edf00: there, a noted result stored under another participant and a noted bundled tool cycle each diverged at the next compile, so the replies after them lost their thinking; at this head they keep it. And a store that refuses the record's state, which agent-framework's own test of an unreadable record uses: at c22f2519, a compile without binds threw the store's read error, and a binding compile its write error; at this head the first never touches the state, and the second logs the failure and goes on.
• A driver (not committed) over a long-running agent's store, under the kv-unified autobiographical strategy with tool rounds, models the provider's check exactly: each block is bound to the system text, tools and every message before it when minted. The host notes each tool round and each stream's end as agent-framework will. 300 turns at a 100k window unless named:
  • without the option, 670 of 742 requests carried a stale block, from the first fold at turn 30; with another writer storing between rounds (89 times), 764 of 768 did;
  • with the option and notes, no request carried a stale block in any scenario: folds at 100k and 200k, the interleaved writes, a moving injection, tools added every 20 turns, restarts mid-turn, reopens, and the option first passed at turn 40 (0 of 641 requests after it);
  • with notes the 100k run kept 9,698 thinking blocks; without notes, 717, with no request refused.
• An agent-framework build that passes the options and sends the notes, not published, drove a packed build of this change before its last round of docs and tests through seven streams: a control, a heartbeat tick, [Continue] before the first round, an empty text block in a reply, a single-round turn, the tool-result guard with a durable audit, and a committing compile run mid-stream through Agent.compileContext(). In the first six, every note was accepted, and each next compile left out nothing, kept every noted reply's thinking, and rendered the messages the stream had sent, taking a result's is_error: false as absent, which a run on Anthropic's API showed the binding does too. In the seventh, the stream's notes under the earlier compile's id returned false.
• A run on Anthropic's API on 2026-10-23 (Haiku 5.5 with the drop control, on an account that enforces the binding and on one that doesn't): moving only a cache marker, onto or off a block before two replies, dropped neither reply's thinking, at equal billed input with real cache reads and writes; changing one word dropped both. So the digest leaves a block's own cache marker out.

Not verified

• No real provider ran this code. The evidence is the suite, the removals, the driver's model of the binding, and the provider runs above of what the binding counts.
• What the binding counts beyond Haiku 5.5: the is_error and cache-marker runs were on Haiku 5.5 alone, and the other binding models weren't run for them.
• agent-framework doesn't pass the options or note its rounds and ends yet.
• That a host's request passes leave a noted row as the stream sent it.
• Record size: one 11-character digest per message the branch last sent, plus the ids of replies sent without thinking, written at each committing compile with binds and each note. The driver's largest was 5.4 KB at a 200k budget, and 13.1 KB at a 2M one.

Automated review

Recommendation: merge and fast-follow. 1 should-fix issue can be fixed after the merge.

Reviewed commit e06edf0 by reading the code, in four stages: a plan by claude-opus-5-5; two readers on every task of it, gpt-6.1-sol (two tasks per call) and claude-haiku-5-5; their findings grouped into issues; and a judge, claude-opus-5-5, that tried to refute each issue. It did not run the code or look at the checks.

Should fix (1)

• Should fix. noteRequestSent digests stored rows without compile's splitMixedToolMessages normalization, so unchanged or split rows falsely diverge. src/context-manager.ts:1762

Minor (1)

1 minor issue

• Minor. Layout adjustment keys 'without' by stored-body id, so a split body's layout price omits thinking that other parts still send. src/context-manager.ts:1275 Cause: layoutEntries keys the 'without' removal by stored-body id, so withoutThinking hits the whole entry although binding decisions are per compiled message. Consequence: layout totalTokens and the body's layout price exclude T1 as well as T2 instead of only T2; returned messages still carry T1, so the reported layout disagrees with what is sent. Case: Store a supported bundled assistant tool cycle containing thinking T1, tool_use, tool_result, thinking T2, and text, and bootstrap a binding record with dropBlock enabled. On the next compile, add an afterUser injection: splitting places the injection after the bundled tool_result, so T1 still matches and is retained while T2 is stripped. Both parts share the same body source, so recording that body's id in 'without' makes layoutEntries call withoutThinking on the entire original entry. The returned messages carry T1, but provenance.layout.totalTokens and the body's layout price exclude both T1 and T2 instead of excluding only T2. Found by gpt-6.1-sol alone.

What the review couldn't read

Between them, the reads of the readers that answered returned every changed line of the change (2121 in all). A line counts when a read by a reader that answered returned it whole: an added line from the diff or from its file, a removed line from the diff. A search that matched it doesn't count.

The plan's note: The diff (about 141k characters) is over one reader's budget, so it is cut into two areas. 'impl' holds every changed source, type, README and changelog file. Its slices read src/context-manager.ts and src/strategies/autobiographical.ts by the line ranges around the changed hunks, not whole, because both files are very large. 'tests' holds the new test file and the changed recall-envelope fixture. No changed file is generated or vendored. The provider's binding rule is the author's claim and can't be checked in the repository. Readers should treat it as an assumption (see facts).

What went wrong along the way (2)

• The plan: the plan has no areas.
• Repaired: the plan had no areas, so the whole change is read as one area by a task with no lens.

[github-actions]

Should fix. noteRequestSent digests stored rows without compile's splitMixedToolMessages normalization, so unchanged or split rows falsely diverge.

Cause: noteRequestSent digests stored rows without applying compile's splitMixedToolMessages normalization.

Consequence: an unchanged tool-result row stored under a non-user participant creates a false divergence; later replies' thinking is stripped; bundled tool-cycle rows that compile splits into several messages are also affected; for a k-part split row, later compiled messages shift by k-1 against the record, so the comparison fails at that row; sticky diverged strips every later owned reply, written into 'without' and kept stripped on later compiles; change-text.md line 20 claim that each stored row is digested as the next compile renders it is false for split rows; no listed test uses a split row; only shards are covered.

Case: Start a binding compile containing U1, then store A1 with thinking and a tool_use, its tool_result under participant 'Tool', and A2 with thinking; note all three ids with the same identity and the originating compileId. The note hashes the result with participant 'Tool', but the next compile normalizes that result to participant 'user'. Despite unchanged content and correctly supplied notes, comparison diverges at the result and removes A2's thinking. Note recording should use the same normalized message sequence as compile; this also affects bundled tool-cycle rows that compile splits into several messages.

Found by both readers (gpt-6.1-sol and claude-haiku-5-5).

We reviewed this at e06edf00. Our answer is to approve. The center of the review was the caller's part, which the description gives "by reading", so we checked it against agent-framework's and connectome-host's main and list what we found.

Ran (macOS, Node 22.21.1, npm ci then npm test):

• The full suite at e06edf00: 2910 tests / 2910 pass / 0 fail / 0 skipped, exit 0. main hasn't moved past 8db49e6, the PR's base, so this is also the merge's suite.

• Nine removals of our own, chosen beside your 69, each breaking one piece against test/thinking-binding.test.ts (57 tests). Each went red:

  • past the record's end counted as vouched (6 red);
  • a cache marker counted in the digest (1);
  • a note under another head kept as vouching (1);
  • another participant's reply allowed to keep thinking (1);
  • the before-record boundary moved from <= to < (6);
  • a note accepted whatever its compileId (1);
  • a dry compile writing the record (4);
  • a compile without binds leaving the record in place (1);
  • the carrier pricing ignoring thinkingBound — liveCarrierPolicy()
    falling back to the configured policy while bound (2, second panel's,
    chosen because none of the first eight touched the pricing leg).

  The file is back to 57/57 with each restored.

The caller's part, read on each repository's main (agent-framework a51c8492, connectome-host ff1f6dc):

• agent-framework: every compile in framework.ts and api/server.ts is dryRun. Committing compiles go through two paths:

  • startStreamWithInjections → assembleActivationRequest, once at a stream's start;
  • the public Agent.compileContext(), which nothing in agent-framework calls.

  So "committing only at a stream's start" holds for agent-framework's own callers. compileContext is the open door: agent-framework's own comment at applyCompileWatermark names "a committing compile, such as compileContext's, run during a live turn" as a case it handles. Your seventh driver stream shows what that costs under this PR: the stream's notes return false and its replies go without thinking, a strip and never a refusal. Non-blocking, and for the companion work rather than this PR: once a host passes binds, compileContext's doc could say to use previewActivation while a stream is open.

• connectome-host: the two committing compiles are the launch checks in runSpawn and runFork (subagent-module.ts:3284, :3604). Both run on a manager createEphemeralAgent opens at subagent/<name> with isolate: true. A fork is launched while its parent streams, but the record is <namespace>/thinking-binding, so the launch compile writes the fork's record and can't touch the parent's. The test "two namespaces on one store" covers that shape. Every other compile in the host is dryRun.

• A request built from compile output (the second half of the caller's part): agent-framework's tool-result guard puts a durable batch's originals into the request only (prepareRequest), never into what the strategy sees. By reading, each way we traced errs toward leaving thinking out, never toward a refused request. After admission the stored placeholder is edited to the originals, and after a withholding it becomes a stub, so the next compile differs from what was recorded at that message. We didn't run this. One direct question rather than an assumption: in your seventh driver stream ("the tool-result guard with a durable audit" kept whole), did the admission land before the stream's end note, or after it? If after, that's the one path we'd want a test on from agent-framework's side when it passes binds — still not this PR's to fix.

Read whole: src/thinking-binding.ts, noteRequestSent, the compile's record write and clear, and the strategy's changes.

• bindThinking is conservative in each direction: a head change voids everything; the first differing message voids itself and all after it; anything past the record's end is unvouched (UNVOUCHED is '', never an 11-character digest); a reply once sent without thinking stays without it.
• A reply stored before the record keeps thinking only under the drop control, and then is reported once ('first'), not at every compile, because it joins without.
• noteRequestSent lines renderAsNewest's output up with the stored rows only.
• The record is the compile's last write, and only when not dry; without binds it clears.
• canonicalJson moved byte-for-byte (scripted diff of the two bodies, identical modulo the export keyword); stripThinkingBlocks is now withoutThinking, with the same filter and raw-form release.
• Carriers priced as under live-strip while bound: thinkingBound is set from each select's own option and reset in finally on both the committing and dry paths, and select is synchronous, so a concurrent preview can't flip it mid-select.

Not verified by us: no real provider; the driver; the agent-framework build; the Anthropic API runs on what the binding counts. We take those as your description states them.

@slimepriestess The head moved after your approval, to c22f251, two commits on e06edf00. We're asking you to re-read that delta before we merge it. The first fixes the automated review's two findings, and the second has our own review's text and test fixes:

• The note digested a stored row as stored, where the compile splits it first (splitMixedToolMessages). A tool result stored under another participant goes as the user's, and a bundled tool cycle goes as several messages. A noted row like either diverged at the next compile, and every reply after it lost its thinking: a strip, never a refusal, but at every turn for a host that stores rows that way. The note now digests each row as the compile sends it, one digest a part.
• The rendered layout left out a split body's whole thinking when only one part's went. It now keeps each entry's thinking as the compile sent it.

Each has a test. Both fail against e06edf00, and breaking either fix alone at the new head fails its own.

Your question about the tool-result guard: the admission landed before the stream's end note. The stream's notes were, in order: round 1's reply with its results marked unstored while the guard held the batch; round 2's note, with round 1's results now as stored and round 2's marked unstored; and the end note, with every row as stored. In that run, the build settled the last batch, stored the last reply, then noted. The next compile kept all four replies' thinking, and its request matched what the stream had sent. The run admitted each batch; a withheld batch, which becomes a stub, wasn't run.

On compileContext: agreed. That doc is agent-framework's to change, not this PR's.

Thank you for the review, and for the nine removals beside ours.

Re-read at c22f251, as asked. The approval stands, two-panel again (Fable first on the delta this time, Opus second, read unanchored in separate worktrees — the numbers below matched on every point before comparison).

• Suite at c22f251: 2912 / 2912 / 0 fail / 0 skipped, exit 0 (Node 22.21.1), in both worktrees independently.
• Red-then-green, both directions: the old source with the new tests fails exactly the two new tests (59 run, 2 fail, 57 old pass). Each fix broken alone at the new head fails its own: the layout's whole-entry strip reinstated → 1 red (its own); the note's row digested whole rather than per part → 2 red — its own plus the split-pricing test, coupled through the record in the conservative direction (a broken digest strips more, never less). Both panels found the same coupling independently.
• Read whole: the compile splits each entry with the same splitMixedToolMessages before binding (context-manager.ts:1236, binding at :1254), so the note's per-part digests line up with the sent messages position for position — the fact that makes fix 1 correct rather than merely matching. thinkingAsSent only ever removes; a body split across parts still goes without whole from the next compile, through without, conservatively. cacheBreakpoint is a message flag outside content, so the digest ignores it. The cache-marker doc claim's narrowing to "as observed in a run" is the right width.
• The earlier nine removals all still bite at c22f251 (the dry-write one now reds 5 where it was 4, the split change's extra coverage). Restored 59/59.

Thank you for the precise answer on the admission timing — "a withheld batch wasn't run" stated plainly is exactly the scope agent-framework's side needs when it picks up binds.

Replying to this comment.

@slimepriestess Two more commits on c22f251, now at 30a7917. We're asking you to re-read c22f251..30a7917 before we merge. Our cross-package check found that a committing compile without binds failed when the store couldn't read state. It was agent-framework's own test, which makes getStateJson throw, that caught it: this PR cleared the binding record at every such compile.

• What changed: "without binds, a committing compile clears the record", which your review read, no longer holds. A compile without binds now neither reads nor writes the record, as on main.
• Why the clear can go: a record an earlier binding compile left is compared at the next binding compile like any other. A message keeps its thinking only while everything up to it matches what that compile sent and its stream noted, a prefix the provider took with that thinking. Nothing past the record's end keeps its thinking, and a note needs the record's own compile id. So the clear bought no safety.
• With binds: a record the store can't read is read as none, under the first-compile rule, and the compile's own record takes its place. One it can't write leaves the record before it, if any, which the compile's stream can't note onto. Either is logged, and neither fails a compile or a note.

The first commit makes that change, and its two tests fail against c22f251. The second is our own review of it: the docs now say a record is written by a committing compile with binds, so a stream's notes still write after a compile without it. It also has two tests, one for that note and one for a failed write with a record before it.

Thank you for the re-read, and for finding the coupling between the two fixes' tests.

Re-read at 30a7917 (c22f251..30a7917), as asked. The approval stands, two-panel again in separate worktrees, numbers matching before comparison.

One retraction first, so the record stays true: our original review read "without binds it clears" approvingly. That behavior is gone, and the replacement is better — a compile without binds now touches no binding state at all, and the clear it replaces was itself the failure your cross-package check caught. The record a binding compile leaves is self-securing by the mechanics we re-traced: the compileId guard stops a stale stream noting onto it, anything stored in the gap is past the record's end and goes without its thinking, without stays stripping, and a model switch voids everything through the identity. Degrades toward less thinking kept, in every direction we could construct.

• Suite at 30a7917: 2913 / 2913 / 0 / 0, exit 0 (Node 22.21.1), both worktrees independently.
• Red-then-green: the old source under the new tests fails exactly the four rewritten pins (60 run, 4 fail). The fail-soft contract is pinned in both directions by targeted breaks: the read catch removed → 1 red ("a record the store can't read or write is logged, and never fails a compile or a note"); writeBindingRecordFor rethrowing → 2 red.
• The earlier removals: one is retired with the clear it pinned; the remaining ten all still bite at 30a7917 (of 60). File restored to 60/60.
• Read whole: clearBindingRecord deleted rather than stranded; every record-I/O failure logs the consequence it causes in the log line itself ("its replies go without their thinking until a compile with binds writes the record") — the diagnostics say what a keeper needs at the moment they'd read them, which is this PR's register throughout.

@slimepriestess Merged at 30a7917 as 4fbe6c94. Thank you for three reads, each with two panels and removals of your own. The retraction in your last one, and the timing question before it, made the record of why this holds better than our own text did.

Until a host passes thinkingBinding with binds, it changes nothing apart from registering the record's state at open.

@antra-tess Flagging for your awareness this PR, which made the following changes (in brief), when a host passes thinkingBinding with binds to compile():

• Signed thinking in the model's own stored replies: sent, so on an account that enforces the binding, a request carrying a block whose request had changed since it was minted was refused with a 400, or the block set aside under the provider's drop control → a reply keeps its thinking only where the compile can vouch for it:
  • from the first message that differs from what the branch last sent, or from the first message when the request's head digests differ, every message goes without its thinking, and past what the branch last sent, nothing keeps it;
  • without dropBlock, a reply stored before the branch's record began never keeps its thinking, so a branch's first binding compile leaves out every reply's thinking;
  • a host that passes thinkingBinding and notes nothing (noteRequestSent) loses each reply's thinking at the compile after it's stored, once the branch has a record.
• A summary's carriers render as under carrierPolicy: 'live-strip', whatever the configured policy.
