Files alone do not establish activation; this repository changes no global Codex setting, and a Codex observation does not verify Claude Code delivery. `node --test .codex/restore-product-context.test.mjs` tests it (CI too): the rule within the first 2,000 characters, the whole output within 10,000 (about 1,500 tokens, under Codex's `additionalContextLimit` of 4,000), both sections verbatim; errors exit nonzero with stderr, with no fail-closed guarantee.

Codebook starts an owned server and Chrome on dynamic loopback endpoints. Existing development locks are rejected and preserved. If a previous owned run has ended but `.next/dev/lock` remains, check the recorded owner PID and listening port before retrying. Preserve any live or unknown owner. Only after both are confirmed gone, retain the stale lock as a diagnostic artifact and move it out of the way, then start with a new operation identity. Codebook does not automatically delete locks.

Neither result establishes G12 editor-chat use or full-product acceptance. The current adapter is `next-dev-webpack`: a trusted local Git root with dependencies already installed, an executable Next development server, a same-origin `entryPath` (default `/`), default `.next/dev` output, and webpack modules/maps that retain the exact original selected source. Codebook starts an owned server and Chrome on dynamic loopback endpoints. Existing development locks are rejected and preserved. If a previous owned run has ended but `.next/dev/lock` remains, check the recorded owner PID and listening port before retrying. Preserve any live or unknown owner. Only after both are confirmed gone, retain the stale lock as a diagnostic artifact and move it out of the way, then start with a new operation identity. Codebook does not automatically delete locks. It does not reuse an unrelated app/debugger, execute caller-supplied shell commands, supply arbitrary debugger expressions, or modify the application's source to add instrumentation. SSH, container, tunnel and virtual workspaces, alternate build directories, Turbopack and multiple actions are outside this adapter's declared scope. One action supports up to eight ordered stops.

One replay shows at a time: while a browser replay is open, Codebook asks you to close it first. If the replay debugger cannot start at that first open (a declined workspace trust, for example), the replay still opens on that moment and the Study pane says on its replay-debugger line why the debugger is missing; **Retry storage / refresh** or Inspect presents it again. A failed open shows its cause with the storage folder replaced by ``. Saved studies list each test replay with its result, its capture and its explained stops, for example `Test replay · Test passed · exit code 0 · capture complete · 2 of 2 stops explained`. The **Application pane** shows a test replay's recorded test output up to the selected moment and nothing printed after it. Its header reads `Recorded test output · s` over the test's file and title path (`` counts from the run's start, paused time included). Lines the test wrote to standard error start with `[stderr] `; terminal colors, cursor moves and other control characters are removed; the Node inspector's own lines fold into one muted line such as `2 Node inspector lines hidden`; and the pane keeps the last 65,536 characters, with a line such as `… 1200 earlier characters not shown` before them. At the result the output ends with the verdict (`Test passed · exit code 0`, `Test failed · exit code ` or `Ended by signal `); a replay that ended before its result says `Recording ended before the test result.`, and one this window is still recording says nothing of an end. Moving through the replay updates the same page in place, so your scroll position, text selection and keyboard focus stay; the pane follows the latest output until you scroll up, and **Jump to latest** follows it again; moving back to a shorter moment does not turn following back on. A page the editor loads again (the pane moved to another window, webviews reloaded) shows the latest moment it had and keeps your choice; a pane the editor replaces follows again. Moving through a long output costs about the 65,536 characters the pane keeps, however many lines it holds or however long a line printed without line feeds is. diff --git a/extension/src/constants.ts b/extension/src/constants.ts index 46e3a6a28..d46bb8537 100644 --- a/extension/src/constants.ts +++ b/extension/src/constants.ts @@ -973,6 +973,10 @@ export const BOOK_PREPARE_TIMEOUT_MS = 20_000 export const BOOK_SOURCE_CONCURRENCY = 4 export const REPOSITORY_BROWSER_PROFILE = 'repository-browser' export const NODE_TEST_PROFILE = 'node-test' +/** The command id of the status item's Save learning replay and its Retry; registered by the extension, run by a click. */ +export const SAVE_LEARNING_REPLAY_COMMAND = 'codebook.saveLearningReplay' +/** The command id of the status item's Open replay and Open retained history. */ +export const OPEN_LEARNING_REPLAY_COMMAND = 'codebook.openLearningReplay' export const NODE_TEST_HISTORY_VERSION = 1 export const NODE_TEST_READER_POSITION_VERSION = 1 export const NODE_TEST_READER_POSITION_LIMIT_BYTES = 4_096 diff --git a/extension/src/extension.ts b/extension/src/extension.ts index a61e3e442..a63cce3e0 100644 --- a/extension/src/extension.ts +++ b/extension/src/extension.ts @@ -34,6 +34,8 @@ import { WIKI_UPDATE_WATCH_POLL_MS, WIKI_UPDATE_WATCH_TIMEOUT_MS, WIKI_UPDATE_WINDOW_CLOSING_ABORT_REASON, + OPEN_LEARNING_REPLAY_COMMAND, + SAVE_LEARNING_REPLAY_COMMAND, } from './constants' import { deployCursorSkill, @@ -2126,7 +2128,7 @@ export function activate( registerCommand(WIKI_CHAT_WATCH_CANCEL_COMMAND, () => { cancelShownWikiChatWatch?.() }), - registerCommand('codebook.saveLearningReplay', async (studyId?: string) => { + registerCommand(SAVE_LEARNING_REPLAY_COMMAND, async (studyId?: string) => { try { await workspace().saveLearningReplay(studyId) } catch (error) { @@ -2143,7 +2145,7 @@ export function activate( registerCommand('codebook.moveLearningSummary', () => workspace().moveLearningSummary(), ), - registerCommand('codebook.openLearningReplay', (studyId: string) => + registerCommand(OPEN_LEARNING_REPLAY_COMMAND, (studyId: string) => workspace().openLearningReplay(studyId), ), registerCommand('codebook.closeRepositoryWiki', () => diff --git a/extension/src/nodeLearningSave.ts b/extension/src/nodeLearningSave.ts index 640647a33..061a66000 100644 --- a/extension/src/nodeLearningSave.ts +++ b/extension/src/nodeLearningSave.ts @@ -1,8 +1,13 @@ -import { NODE_TEST_PROFILE } from './constants' +import { + NODE_TEST_PROFILE, + OPEN_LEARNING_REPLAY_COMMAND, + SAVE_LEARNING_REPLAY_COMMAND, +} from './constants' import type { NodeTestHistoryStore } from './nodeTestHistoryStore' import type { StudyRecord, StudyService } from './service' import { describeNodeLearningSave, + NODE_LEARNING_SAVE_ACTION, type NodeLearningSaveMessage, } from './utils/describeNodeLearningSave' import type { NodeTestVerdict } from './utils/describeNodeTestResult' @@ -22,10 +27,12 @@ export type NodeLearningSaveHost = { ask: (text: string, actions: readonly string[]) => Promise /** Shows a notification; resolves to the action chosen, or `undefined`. */ notify: ( - severity: 'warning' | 'error', + severity: 'information' | 'warning' | 'error', text: string, actions: readonly string[], ) => Promise + /** The material revision the store holds for a test history, from the summary projection the library lists (not this window's cache, which only this window's saves move); `undefined` while the history is not listed. */ + materialRevision: (studyId: string) => number | undefined /** Opens a test replay (Open replay, Open retained history). */ open: (studyId: string) => Promise /** Reports one unexpected failure to the Output › Codebook channel. */ @@ -58,10 +65,6 @@ type SaveState = } | { stage: 'stop-rejected' | 'read-failed' | 'seal-failed'; cause: string } -/** The command a status item click runs to save a test run's learning replay. */ -const SAVE_COMMAND = 'codebook.saveLearningReplay' -/** The command a status item click runs to open a test replay. */ -const OPEN_COMMAND = 'codebook.openLearningReplay' /** The refusal of a Save for a test run that recorded nothing, worded as the browser run's ({@link StudyWorkspace.saveLearningReplay}). */ const NOTHING_RECORDED = 'No recorded Codebook session is available.

One replay shows at a time: while a browser replay is open, Codebook asks you to close it first. Saved studies list each test replay with its result, its capture and its explained stops, for example `Test replay · Test passed · exit code 0 · capture complete · 2 of 2 stops explained`. diff --git a/extension/src/resources.ts b/extension/src/resources.ts index bd988cc74..ee653ab88 100644 --- a/extension/src/resources.ts +++ b/extension/src/resources.ts @@ -19,6 +19,7 @@ import { IMAGE_LIMIT_BYTES, REPOSITORY_RUN_TIMEOUT_MS, SOURCE_LIMIT_BYTES, + NODE_TEST_MINIMUM_VITEST_MAJOR, NODE_TEST_PROFILE, ACTIVE_TIMEOUT_MS, MAX_EXPLANATIONS, @@ -228,7 +229,7 @@ export async function readResource( since: NODE_TEST_SINCE_API_1_8_HELP, example: NODE_TEST_HELP_EXAMPLE, walkthrough: [ - 'codebook_status: copy instanceId; profiles node-test must be ready (its missing list names a root Vitest that is missing or older than 4).', + `codebook_status: copy instanceId; profiles node-test must be ready (its missing list names a root Vitest that is missing or older than ${NODE_TEST_MINIMUM_VITEST_MAJOR}).`, 'codebook://help/node-test (this resource): the configuration schema, the example and these steps.', 'codebook_sources, then codebook_source for the test file and each cited source: copy each path and its hash, and choose the stop lines from numberedText.', 'codebook_publish_book: publish the article whose node cites the stop sources; copy bookId, revision and the node id.', @@ -243,8 +244,7 @@ export async function readResource( ], testSelection: 'testTitles cites exactly one test: every enclosing describe title, outermost first, then the test title, exactly as Vitest reports them, for example ["job scheduler", "runs a delayed job after its timer"].

Neither result establishes G12 editor-chat use or full-product acceptance. The current adapter is `next-dev-webpack`: a trusted local Git root with dependencies already installed, an executable Next development server, a same-origin `entryPath` (default `/`), default `.next/dev` output, and webpack modules/maps that retain the exact original selected source. Codebook starts an owned server and Chrome on dynamic loopback endpoints. Existing development locks are rejected and preserved. If a previous owned run has ended but `.next/dev/lock` remains, check the recorded owner PID and listening port before retrying. Preserve any live or unknown owner. Only after both are confirmed gone, retain the stale lock as a diagnostic artifact and move it out of the way, then start with a new operation identity. Codebook does not automatically delete locks. It does not reuse an unrelated app/debugger, execute caller-supplied shell commands, supply arbitrary debugger expressions, or modify the application's source to add instrumentation. SSH, container, tunnel and virtual workspaces, alternate build directories, Turbopack and multiple actions are outside this adapter's declared scope. One action supports up to eight ordered stops. Version 1 retains browser stops within one citation. Version 2 declares each stop's participant and citation, including server-action modules in the owned Next worker. Server breakpoint registration may be pending before input; actual pauses must verify executed module bytes, source maps and native coordinates. Installed host compatibility remains subject to native validation. diff --git a/extension/src/constants.ts b/extension/src/constants.ts index 46e3a6a28..073277433 100644 --- a/extension/src/constants.ts +++ b/extension/src/constants.ts @@ -1366,3 +1366,15 @@ export const HTML_PARSER_HEADING_NAMES = new Set([ 'h5', 'h6', ]) + +/** How long a test history's seal waits before its one retry after a transient file-system failure ({@link TRANSIENT_SEAL_ERROR_CODES}). */ +export const SEAL_RETRY_DELAY_MS = 200 + +/** The file-system error codes that may pass by themselves, so the seal of a test history is tried once more ({@link StudyService.sealNodeHistory}); any other code fails the seal at once. */ +export const TRANSIENT_SEAL_ERROR_CODES: readonly string[] = [ + 'EMFILE', + 'ENFILE', + 'EBUSY', + 'EAGAIN', + 'EPERM', +] diff --git a/extension/src/service.ts b/extension/src/service.ts index 01aa276ac..451aa4e6d 100644 --- a/extension/src/service.ts +++ b/extension/src/service.ts @@ -36,9 +36,11 @@ import { REPOSITORY_RUN_TIMEOUT_MS, REPOSITORY_SETUP_TIMEOUT_MS, RETIRED_PRESENTATION_REFUSAL, + SEAL_RETRY_DELAY_MS, SELECTABLE_PRESENTATION_MODE, PRESENTATION_MODE_IDS, STUDY_PRESENTATIONS, + TRANSIENT_SEAL_ERROR_CODES, } from './constants' import { NodeLearningRevisionChangedError, @@ -140,6 +142,7 @@ import { sanitizeCause, type CauseRoots } from './utils/sanitizeCause' import { sanitizedStack } from './utils/sanitizedStack' import { snapshotSourceHashes } from './utils/snapshotSourceHashes' import { studyErrorNamingCause } from './utils/studyErrorNamingCause' +import { systemErrorCode } from './utils/systemErrorCode' import { thrownMessage } from './utils/thrownMessage' import { waitForNextRunState } from './utils/waitForNextRunState' @@ -393,6 +396,9 @@ export class StudyService { private readonly startKeys = new Map() private readonly maintenance: ReturnType private stopping = false + /** Waits before the seal's one retry; a test replaces it so no clock runs. */ + sealRetryDelay: (milliseconds: number) => Promise = (milliseconds) => + new Promise((resolve) => setTimeout(resolve, milliseconds)) private shutdownPromise?: Promise /** @@ -3591,7 +3597,8 @@ export class StudyService { record.nodeStops?.length === expectedStops const reason = complete ? undefined : this.partialHistoryReason(record) try { - record.nodeHistoryHash = await writer.finish( + record.nodeHistoryHash = await this.finishNodeHistory( + writer, complete ?

Neither result establishes G12 editor-chat use or full-product acceptance. The current adapter is `next-dev-webpack`: a trusted local Git root with dependencies already installed, an executable Next development server, a same-origin `entryPath` (default `/`), default `.next/dev` output, and webpack modules/maps that retain the exact original selected source. Codebook starts an owned server and Chrome on dynamic loopback endpoints. Existing development locks are rejected and preserved. If a previous owned run has ended but `.next/dev/lock` remains, check the recorded owner PID and listening port before retrying. Preserve any live or unknown owner. Only after both are confirmed gone, retain the stale lock as a diagnostic artifact and move it out of the way, then start with a new operation identity. Codebook does not automatically delete locks. It does not reuse an unrelated app/debugger, execute caller-supplied shell commands, supply arbitrary debugger expressions, or modify the application's source to add instrumentation. SSH, container, tunnel and virtual workspaces, alternate build directories, Turbopack and multiple actions are outside this adapter's declared scope. One action supports up to eight ordered stops. Version 1 retains browser stops within one citation. Version 2 declares each stop's participant and citation, including server-action modules in the owned Next worker. Server breakpoint registration may be pending before input; actual pauses must verify executed module bytes, source maps and native coordinates. Installed host compatibility remains subject to native validation. diff --git a/extension/src/ownedNodeTestRun.ts b/extension/src/ownedNodeTestRun.ts index 018d63c84..f66354e55 100644 --- a/extension/src/ownedNodeTestRun.ts +++ b/extension/src/ownedNodeTestRun.ts @@ -247,12 +247,12 @@ export class OwnedNodeTestRun { ) const endpoint = await this.owned.inspectorEndpoint(signal) signal.throwIfAborted() - // The pause is captured at the declared column, so a registration acknowledged at another column fails here, before the test continues. + // The debugger may bind the declared line at another column; the stop is then captured there (F155).

API 1.7 changed two answers: `codebook_source`, and `codebook_read_resource` for a book's cited source, answer the source's lines as `numberedText` and no longer as `text`, because the two copies doubled every source answer. An MCP `resources/read` of a cited source's URI still answers its exact text. No request states an API version, so a client written for API 1.6 gets these answers too: where it read `text`, it reads `numberedText` (each line after its one-based number and a tab, the lines joined by a line feed). API 1.7 also added a second reason a run resource names, and its evidence is refused with, once the run's saved study was removed: `The archive of this run's saved study is no longer in the study library: its files were removed by hand or by another Codebook window.`, beside `The learner moved this saved study to the Trash.` for a study deleted in this window (see [Delete a saved study](#delete-a-saved-study)). API 1.6 added, without changing the meaning of an existing field: `declaredSource`, the position you declared (`requestedSource` is its older name); `armed`, the place Codebook requested the breakpoint at when that differs; `place`, one sentence that names the line a stop paused on when the debugger bound it on another line than you declared; and `answer: "next"` in the run resource's `continueArguments`, with which a continuation answers with the next state (the next observation, the observed result or the failure). API 1.6 also added `numberedText` to the answer of `codebook_source` and to the answer of `codebook_read_resource` for a book's cited source: the source's lines, each after its one-based number and a tab. Cycle 0029 delivered private preview **0.2.12** and Cycle 0018 **0.2.2**. `repository-browser` appears in `codebook_status.profiles` and its exact input schema at `codebook://help/repository-browser`.

API 1.7 changed two answers: `codebook_source`, and `codebook_read_resource` for a book's cited source, answer the source's lines as `numberedText` and no longer as `text`, because the two copies doubled every source answer. An MCP `resources/read` of a cited source's URI still answers its exact text. No request states an API version, so a client written for API 1.6 gets these answers too: where it read `text`, it reads `numberedText` (each line after its one-based number and a tab, the lines joined by a line feed). API 1.7 also added a second reason a run resource names, and its evidence is refused with, once the run's saved study was removed: `The archive of this run's saved study is no longer in the study library: its files were removed by hand or by another Codebook window.`, beside `The learner moved this saved study to the Trash.` for a study deleted in this window (see [Delete a saved study](#delete-a-saved-study)). API 1.6 added, without changing the meaning of an existing field: `declaredSource`, the position you declared (`requestedSource` is its older name); `armed`, the place Codebook requested the breakpoint at when that differs; `place`, one sentence that names the line a stop paused on when the debugger bound it on another line than you declared; and `answer: "next"` in the run resource's `continueArguments`, with which a continuation answers with the next state (the next observation, the observed result or the failure). API 1.6 also added `numberedText` to the answer of `codebook_source` and to the answer of `codebook_read_resource` for a book's cited source: the source's lines, each after its one-based number and a tab. Cycle 0029 delivered private preview **0.2.12** and Cycle 0018 **0.2.2**. `repository-browser` appears in `codebook_status.profiles` and its exact input schema at `codebook://help/repository-browser`. External-client execution, source/value pauses, recording/restart, interrupted evidence and native reader flows have separate development evidence in both editors. [Cycle 0017 installed evidence](https://github.com/laststance/codebook/blob/273660c49bb1aa5a88082ab6d43cd1ebae6ee7cf/docs/cycles/evidence/0017/native-validation.md) adds one unchanged real-repository action, live/replay modes and Wiki returns in both editors; its Cursor restart failure was later repaired in the bounded Cycle 0018 schedule. Neither result establishes G12 editor-chat use or full-product acceptance. The current adapter is `next-dev-webpack`: a trusted local Git root with dependencies already installed, an executable Next development server, a same-origin `entryPath` (default `/`), default `.next/dev` output, and webpack modules/maps that retain the exact original selected source. Codebook starts an owned server and Chrome on dynamic loopback endpoints. Existing development locks are rejected and preserved. If a previous owned run has ended but `.next/dev/lock` remains, check the recorded owner PID and listening port before retrying. Preserve any live or unknown owner. Only after both are confirmed gone, retain the stale lock as a diagnostic artifact and move it out of the way, then start with a new operation identity. Codebook does not automatically delete locks. It does not reuse an unrelated app/debugger, execute caller-supplied shell commands, supply arbitrary debugger expressions, or modify the application's source to add instrumentation. SSH, container, tunnel and virtual workspaces, alternate build directories, Turbopack and multiple actions are outside this adapter's declared scope. One action supports up to eight ordered stops. Version 1 retains browser stops within one citation. Version 2 declares each stop's participant and citation, including server-action modules in the owned Next worker. Server breakpoint registration may be pending before input; actual pauses must verify executed module bytes, source maps and native coordinates. Installed host compatibility remains subject to native validation. diff --git a/extension/src/resources.ts b/extension/src/resources.ts index 4c08cc6ae..bb2d94ab4 100644 --- a/extension/src/resources.ts +++ b/extension/src/resources.ts @@ -245,7 +245,7 @@ export async function readResource( testSelection: 'testTitles cites exactly one test: every enclosing describe title, outermost first, then the test title, exactly as Vitest reports them, for example ["job scheduler", "runs a delayed job after its timer"].

The chat claims saved learning only when the run reads `studyOutcome` `demonstrated`, `nodeTest.learningCoverage` `complete` and an empty `nodeTest.captureMissing` (a run resource without those fields supports no such claim), says when a test did not pass and names its exit code or signal, and points you to **Save learning replay** and **Open replay**.

This version holds the first: the test run's start, stops and refusals, saving and storing test replays, causes that name no private path, the bundled skill and the tests that failed under load. The Application pane and the Study section come with the second, the recorded-source tab and the moves between moments with the third. + +**Starting a test run.** + +- **A full library is said before the start.** While saved studies and test histories take every place of the Saved Study Limit, `codebook_status` reads the `node-test` profile not ready and names the places taken and the limit. A start is refused with `PREREQUISITE_MISSING`, worded as the study library's own refusal: raise **Codebook: Saved Study Limit** in the Settings of this editor profile, or delete a saved study from Saved studies; only the learner can do either. +- **Checks before the history begins.** The cited files, the editors' open documents of the cited sources and the repository's root Vitest program are checked before a history begins, so a refused start leaves no empty test replay behind. A root `node_modules/vitest` that links outside the repository is named as such: Codebook does not run it. +- **Stops where the debugger binds them.** A declared stop that the debugger binds at another column of its line is accepted and captured where it binds. A refused stop position names the stop (`source` or `additionalStops[n]`), its `anchorIndex`, the cited path and lines, and which check failed, with what to send instead. + +**During and after a test run.** + +- **A stop before the first stop reads stopped**, not refused, and offers no `read-history`. After a stop whose release failed, the run offers only `stop`, and a continue is refused with `STALE_PAUSE`. +- **A seal that meets a passing failure is tried once more.** A history's seal that fails with `EMFILE`, `ENFILE`, `EBUSY`, `EAGAIN` or `EPERM` is retried once after 200 ms. +- **Empty and damaged histories.** A test history that ends with no entry is removed when it seals: it is listed nowhere and takes no place of the limit, and its run offers no `read-history`. A history that holds a saved learning material or understanding marks is kept, and so is one whose seal records entries but whose journal was lost: a status call or a list never removes it. + +**Saving the learning.** + +- **Save before the first stop does nothing** and says `Nothing to save yet: the test run has not reached its first stop.`, and the run goes on. +- **The agent's claim of saved learning** also needs `nodeTest.captureMissing` empty (bundled skill 1.0.47). The run resource and the `codebook://node-history` resource list the capture gaps; when the seal could not read them for a passing reason, the next learning-material save reads them again. +- **A replay debugger that cannot start** (a declined workspace trust, the capture timeout) no longer fails the open: the replay opens on its moment, the Study pane says `The replay debugger could not start: . Select this stop or use Inspect in native debugger to restart it.`, and Retry starts it again. A debugger you stopped stays stopped when you move to an output or the result. +- **`codebook_playback` refuses a test replay** with `PLAYBACK_PROFILE_UNSUPPORTED`, also one of an earlier session that this window has not listed yet. + +**Causes name no private path.** Every cause an agent or a learner reads (MCP answers and refusals, the run resource, `codebook_status`, Saved studies, the book catalog, notices, Output › Codebook) shows the extension's storage folder as ``, the opened repository as `` and the home directory as `~`, also under their real paths.

No stored format changes: test histories, learning materials and reader positions written by 0.2.35.0 open unchanged, and those written now open in 0.2.35.0. A history sealed with no entry by an earlier version is removed when a list or a count meets it, unless it holds learning material or understanding marks. + +**Not observed.** No native run of this version yet; the native checks of this cycle run with its second and third pull requests.
