From 26c87013ec195cbcc2a585d2d96579303640cd6b Mon Sep 17 00:00:00 2001 From: Brennan Benson <79079362+brennanb2025@users.noreply.github.com> Date: Fri, 9 Oct 2026 18:50:36 -0700 Subject: [PATCH 01/62] Carry a person's stopped messages to the agent with their next send A message a person sent and then stopped before the agent started on it was kept on screen as "Stopped manually" but never reached the agent. The delivery loop now derives the stopped messages the agent is still owed, names them on the next ordinary send's handover row, and each agent receives them in that same write as framed context (Claude and Pi: framed text and images in the prompt; ACP: leading blocks; Codex: turn/start additionalContext, or framed input items for images and steers). Codex withdrawals that may have reached the agent are marked so they are never carried. --- src/main/acp/acp-prompt-content.ts | 27 +++ .../acp/acp-structured-session-adapter.ts | 19 +- .../claude-structured-dispatch-content.ts | 31 +++ src/main/claude/claude-structured-dispatch.ts | 6 +- .../claude-structured-session-adapter.ts | 4 + .../codex/codex-structured-session-adapter.ts | 1 + .../codex/codex-structured-stopped-history.ts | 48 ++++ .../codex-structured-turn-end-settlement.ts | 6 +- src/main/codex/codex-structured-turn-start.ts | 68 ++++-- .../journal-dispatch-reducer.ts | 16 ++ .../agent-session-journal/journal-reducer.ts | 5 +- .../journal-rewind-submission-retirement.ts | 1 + .../journal-row-builders.ts | 3 +- .../journal-row-schema.ts | 3 + .../journal-store-contracts.ts | 7 +- .../agent-session-journal/journal-store.ts | 3 + ...structured-agent-session-adapter-router.ts | 3 + .../structured-agent-session-adapter.ts | 10 + .../structured-agent-session-command-turn.ts | 2 + .../structured-agent-session-delivery-loop.ts | 3 +- ...red-agent-session-stopped-history-frame.ts | 45 ++++ ...agent-session-stopped-history-selection.ts | 74 +++++++ .../structured-agent-session-turns.ts | 16 +- ...-agent-session-unopened-send-withdrawal.ts | 9 +- src/main/pi/rpc-prompt.ts | 30 +++ src/main/pi/rpc-session-adapter.ts | 7 +- src/shared/agent-session-failure.ts | 10 +- .../agent-session-stopped-history.test.ts | 208 ++++++++++++++++++ src/shared/agent-session-stopped-history.ts | 105 +++++++++ 29 files changed, 722 insertions(+), 48 deletions(-) create mode 100644 src/main/codex/codex-structured-stopped-history.ts create mode 100644 src/main/native-chat/agent-session-wire/structured-agent-session-stopped-history-frame.ts create mode 100644 src/main/native-chat/agent-session-wire/structured-agent-session-stopped-history-selection.ts create mode 100644 src/shared/agent-session-stopped-history.test.ts create mode 100644 src/shared/agent-session-stopped-history.ts diff --git a/src/main/acp/acp-prompt-content.ts b/src/main/acp/acp-prompt-content.ts index 1a461602587e..e9dc9c504b1a 100644 --- a/src/main/acp/acp-prompt-content.ts +++ b/src/main/acp/acp-prompt-content.ts @@ -25,6 +25,7 @@ import { acpAgentName } from './acp-structured-acquire' import type { AcpStructuredConnection } from './acp-structured-connection' import { acpSessionAcceptsImages } from './acp-structured-options' import type { ContentBlock } from './generated/acp-protocol.generated' +import { withStoppedHistory } from '../native-chat/agent-session-wire/structured-agent-session-stopped-history-frame' const ACP_IMAGE_MIME_TYPES = new Set(['image/png', 'image/jpeg', 'image/gif', 'image/webp']) /** A prompt is one JSON-RPC line; this leaves room for the request around its blocks. */ @@ -157,3 +158,29 @@ export async function acpDispatchPrompt( throw error } } + +/** Whether stopped history fits beside `body` in one prompt. */ +export async function acpStoppedHistoryFits( + body: AgentJournalMessageItem, + history: readonly AgentJournalMessageItem[], + session: Parameters[1] +): Promise { + return Array.isArray(await acpDispatchPrompt(withStoppedHistory(body, history), session)) +} + +/** The prompt with its stopped history as leading framed blocks.

fingerprint reconciliation After a host crash, restart reconciliation matches an unsettled send to the agent's transcript by fingerprint. A carrier's transcript copy leads with its stopped history, so it could never match and would read as never delivered, which would also release its history again. Like a send with an attachment, it now stays unconfirmed. --- .../journal-restart-reconciliation.test.ts | 32 +++++++++++++++++++ .../journal-restart-reconciliation.ts | 5 ++- 2 files changed, 36 insertions(+), 1 deletion(-) diff --git a/src/main/native-chat/agent-session-journal/journal-restart-reconciliation.test.ts b/src/main/native-chat/agent-session-journal/journal-restart-reconciliation.test.ts index 8e541f110b00..83c583a58200 100644 --- a/src/main/native-chat/agent-session-journal/journal-restart-reconciliation.test.ts +++ b/src/main/native-chat/agent-session-journal/journal-restart-reconciliation.test.ts @@ -190,6 +190,38 @@ describe('reconcileJournalSubmissionsAgainstHistory', () => { expect(journal.submissions()[0]?.dispatchState).toBe('unknown') }) + it('leaves a send that carried stopped history unknown: its provider copy leads with that history', async () => { + const journal = await open() + for (const clientMessageId of ['stopped', 'cm_1']) { + await journal.appendSubmission({ + clientMessageId, + payloadFingerprint: digestPayload(clientMessageId), + body: userMessage(clientMessageId), + fence: 1, + handoverRecorded: true + }) + } + await journal.resolveDispatch({ + clientMessageId: 'cm_1', + state: 'pending', + fence: 1, + turnScope: AGENT_JOURNAL_THREAD_SCOPE, + carries: ['stopped'] + }) + const restarted = await open() + await restarted.markPendingSubmissionsUnknown(2) + + const settled = await reconcileJournalSubmissionsAgainstHistory({ + journal: restarted, + fence: 2, + history: window([]) + }) + + expect(settled).toEqual([]) + expect(restarted.submission('cm_1')?.dispatchState).toBe('unknown') + expect(restarted.stoppedHistoryCarried().get('cm_1')).toEqual(['stopped']) + }) + it('leaves multi-block text sends unknown because Claude joins them before recording history', async () => { const journal = await reopenAfterCrash( { diff --git a/src/main/native-chat/agent-session-journal/journal-restart-reconciliation.ts b/src/main/native-chat/agent-session-journal/journal-restart-reconciliation.ts index cc59c95893cd..b44ecc5e78f5 100644 --- a/src/main/native-chat/agent-session-journal/journal-restart-reconciliation.ts +++ b/src/main/native-chat/agent-session-journal/journal-restart-reconciliation.ts @@ -55,7 +55,10 @@ function comparableSubmissions(journal: AgentSessionJournal): AgentJournalSubmis if ( (submission.dispatchState !== 'pending' && submission.dispatchState !== 'unknown') || // Never handed over, so provider history cannot hold it. - isQueuedAgentJournalSubmission(submission) + isQueuedAgentJournalSubmission(submission) || + // The provider's copy leads with the stopped history it carried, so its fingerprint cannot + // match; like an attachment's, its absence is no evidence and it stays `unknown`. + journal.stoppedHistoryCarried().has(submission.clientMessageId) ) { return false } From 19a943dbf08ea271c5d322b7c0418be0684138f2 Mon Sep 17 00:00:00 2001 From: Brennan Benson <79079362+brennanb2025@users.noreply.github.com> Date: Sat, 10 Oct 2026 02:31:17 -0700 Subject: [PATCH 04/62] Owe a stopped message only on proof it never reached the agent; carry Codex history as input - Codex: every stopped message rides as leading framed input on turn/start and turn/steer (an older Codex silently ignores additionalContext and would read as delivered); add a Codex fit check against its 1,048,576-character input limit. - Flip the marker: a withdrawal is owed only with `neverReachedAgent`, written where Orca proves it (host-held Stop, ACP held steer, Claude queue clear, a start the Stop ended).

<79079362+brennanb2025@users.noreply.github.com> Date: Sun, 11 Oct 2026 20:26:48 -0700 Subject: [PATCH 14/62] Prepare each send once with the stopped history that fits, in one batch frame Stopped messages now reach the agent in one frame ahead of the next send: a header saying they are earlier, stopped history, one tagged element each with its images numbered in the order sent, then a 'User message:' label. Only a '<' that would open or close the frame's own tags is escaped. Each adapter prepares the send once (prepareDispatch): images are read once, each message's cost is weighed once against that agent's real limits, and the result is the exact payload plus the ordered ids inside it. The host lists those ids on the pending row and dispatch writes that same payload, so what a row says it carried is what the agent got. A message that does not fit goes without its images, then shortened with a marker; only when not even that fits does it wait, and the frame says how many were left out. A plain send with nothing owed is prepared and written exactly as before. ACP measures every prompt's whole line, text included, and refuses a text-only message too long for one line before writing it.

A rewind to before that turn kept the bubble and its append record, while Codex dropped the injected pair, so the message read as covered when the agent no longer had it. The reducer now keeps each record's row position. A rewind restates a record only when that row precedes the rewound turn, and writes it back after the row it followed, so a later rewind compares the same way; the same-epoch rebuild after a /clear takes back every record after the floor first. A stopped send is restated with its submission and rejection rows only: the queued withdrawal never wrote a handover row. --- .../journal-context-rewind.ts | 17 +++- .../journal-epoch-replacement.ts | 52 +++++----- .../agent-session-journal/journal-reducer.ts | 11 ++- .../journal-rewind-restated-send-rows.ts | 73 ++++---------- .../journal-row-schema.ts | 4 +- .../journal-stopped-message-appends.test.ts | 12 ++- .../journal-stopped-message-appends.ts | 19 +++- ...ent-session-stopped-history-rewind.test.ts | 42 +++++++- ...ured-agent-session-stopped-history.test.ts | 4 +- .../structured-rewind-recovery.ts | 3 +- .../structured-rewind-restated-sends.ts | 95 +++++++++++++------ ...ructured-rewind-retained-host-rows.test.ts | 20 ++-- .../structured-rewind-retained-host-rows.ts | 2 +- .../agent-session-stopped-history.test.ts | 4 +- src/shared/agent-session-stopped-history.ts | 6 +- 15 files changed, 220 insertions(+), 144 deletions(-) diff --git a/src/main/native-chat/agent-session-journal/journal-context-rewind.ts b/src/main/native-chat/agent-session-journal/journal-context-rewind.ts index 01a9d4f66cc3..cd77bfee9535 100644 --- a/src/main/native-chat/agent-session-journal/journal-context-rewind.ts +++ b/src/main/native-chat/agent-session-journal/journal-context-rewind.ts @@ -17,6 +17,7 @@ import { journalRestatedSendRows } from './journal-rewind-restated-send-rows' import { journalQueuePauseRestatement } from './queued-message-pause' +import { buildJournalStoppedMessageAppendRow } from './journal-stopped-message-appends' import type { JournalQueuedMessages } from './journal-queued-messages' import type { JournalRow } from './journal-row-schema' @@ -66,6 +67,20 @@ export async function rewindJournalContext(input: { ...(retireSubmission ?

Right before writing, both agents check again that the child, connection and fence are the same and that no turn runs, by the agent's account or Orca's journal; a failed check is refused, so the message stays owed. Reading a stopped message's images has its own 2 s limit and the write and its settlement another 2 s, so a send or Stop queued behind a stalled append waits about 4 s at most; work abandoned on a timeout never writes later. A message with nothing left to read is logged as such, not as unknown. Claude: the append keeps only a uuid observer. Its own lifecycle, echo and result settle it and stay out of turn tracking, even late; its running, init and idle frames are left alone. It holds the child from rest only while unsettled, and a child that ends settles it from what the writes prove, so frames it never took are refused. Codex: every inject error is unknown.

Like ACP agents and Pi, it now gets them at the front of the person's next words-only send, followed by the "[Request interrupted by user]" record. Codex keeps thread/inject_items right before the send, idle only, at most once; a Codex without the method is refused and its sends carry them instead. One selection serves both: words only, the newest that fit a 1 MiB encoded bound, in the order sent, older ones left out and covered. A send with attachments carries nothing, so history can never push a send past an agent's limits; the per-agent prepare and fit modules, stopped-image reads and Codex version plumbing go. The injection record is renamed for what it is.

Its next turn-opening send carries them at the front, the same text every other agent gets, and the carrier's own pending row records what it carries. That removes the injection module, its host-only journal row and reducer handling, the adapter and router hooks, the unsupported-method fallback flag, and the hiding in Session History that only injected items needed. A Codex rewind rebuilds kept messages from Codex's copy, which now leads with the carried words, so a person's own message keeps the words Orca recorded, as the live fold already does. The per-message size allowance is now the inline framing itself. Measured with real Codex 0.159.0 before building: inline acted on "go ahead" 8/8, never on "ignore", and 0/21 on unrelated follow-ups, matching the injected pair and a real Stop. --- .../session-scanner-codex-parser.test.ts | 55 ----------- .../session-scanner-first-user-prompt.ts | 7 +- .../session-scanner-text-normalization.ts | 4 +- .../codex-stopped-message-injection.test.ts | 77 ---------------- .../codex/codex-stopped-message-injection.ts | 72 --------------- .../codex/codex-structured-session-adapter.ts | 7 -- .../codex/codex-structured-session-state.ts | 2 - .../agent-session-journal/journal-reducer.ts | 16 +--- .../journal-restart-reconciliation.test.ts | 2 +- .../journal-restart-reconciliation.ts | 2 +- .../journal-row-schema.ts | 17 ---- .../journal-stopped-history-carried.test.ts | 89 ------------------ .../journal-stopped-message-injections.ts | 90 ------------------ .../journal-store-collaborators.ts | 3 - .../agent-session-journal/journal-store.ts | 8 +- .../agent-session-journal-batch.ts | 5 +- ...structured-agent-session-adapter-router.ts | 16 ---- .../structured-agent-session-adapter.ts | 3 +- .../structured-agent-session-delivery-loop.ts | 3 +- ...ueued-message-rig-provider.test-fixture.ts | 13 +-- ...session-queued-message-rig.test-fixture.ts | 1 - .../structured-agent-session-rewind.test.ts | 9 +- ...d-agent-session-stopped-history-adapter.ts | 23 ----- ...agent-session-stopped-history-selection.ts | 92 +++---------------- ...ured-agent-session-stopped-history.test.ts | 63 ++----------- .../structured-agent-session-turns.ts | 23 +---- .../structured-rewind-retained-host-rows.ts | 15 +-- .../agent-session-stopped-history.test.ts | 22 +---- src/shared/agent-session-stopped-history.ts | 21 ++--- 29 files changed, 63 insertions(+), 697 deletions(-) delete mode 100644 src/main/codex/codex-stopped-message-injection.test.ts delete mode 100644 src/main/codex/codex-stopped-message-injection.ts delete mode 100644 src/main/native-chat/agent-session-journal/journal-stopped-history-carried.test.ts delete mode 100644 src/main/native-chat/agent-session-journal/journal-stopped-message-injections.ts delete mode 100644 src/main/native-chat/agent-session-wire/structured-agent-session-stopped-history-adapter.ts diff --git a/src/main/ai-vault/session-scanner-codex-parser.test.ts b/src/main/ai-vault/session-scanner-codex-parser.test.ts index cc3b961a15e9..396e43c1b44e 100644 --- a/src/main/ai-vault/session-scanner-codex-parser.test.ts +++ b/src/main/ai-vault/session-scanner-codex-parser.test.ts @@ -6,7 +6,6 @@ import { createCodexSessionResumeState, parseCodexSessionFile } from './session-scanner-codex-parser' -import { withFullFirstUserPromptCapture } from './session-scanner-first-user-prompt-capture' import type { TranscriptMessage } from './session-transcript-consumers' let tempRoots: string[] = [] @@ -109,60 +108,6 @@ describe('parseCodexSessionFile', () => { }) }) - describe("Codex's own record of a Stop", () => { - const MARKER = - '\nThe user interrupted the previous turn on purpose.
