From 7b1ada129a1e049da2442ac9bb567ab19c323142 Mon Sep 17 00:00:00 2001 From: Ryota Murakami Date: Wed, 21 Oct 2026 23:43:09 +0900 Subject: [PATCH 01/25] F2: restore the owner's re-entry rule within the hook context limit The compaction hook printed all of AGENTS.md (39,738 bytes). Claude Code injects hook context above 10,000 characters only as a 2,000-character preview, so the restore order did not reach the agent whole. The hook now prints the owner's rule first (PRODUCT_GOAL.md in full and the approved PNG, then the cycle Issue and AGENTS.md), the scope sentence and the Mandatory entry and Owner directions sections verbatim (about 6,000 characters), and keeps the rule when those sections outgrow the limit. AGENTS.md carries the owner's rules of 2026-10-21: the re-entry rule after every compaction, varied questions with learning fitted to the question, and the development chats (GPT6 Luna in Copilot Chat, Grok 4.6 high in Cursor).

recording finalized with the sealed journal's hash; recordingAvailable/replayAvailable; nodeTest.testResult, learningCoverage and learningMissing from the run's coverage cache (EN2); nextActions save-node-learning - Lifecycle (EN4-EN6): the run owns its in-flight continuation and Stop settles it before the seal; the seal's complete comes from the test's own facts; a release error is cleared by a successful retry; OwnedNodeTestRun.complete keeps the exit facts of a failing run without a report and removes the report only after the check settled; hasRunEnded counts a completed test - Refusals at preparation (EN1): the deterministic file checks run before the history begins; a refused run records nothing and frees its slot and start key ('refused-at-preparation') - codebook_stop answers HISTORY_SEAL_FAILED with isError and the run state after a failed seal (test history or browser recording finish); codebook_playback refuses a test replay with PLAYBACK_PROFILE_UNSUPPORTED before the presentation-idle check - Store: finish() returns the sealed journal's hash; list() is a memoized summary projection read at most four at a time; step refusals are typed INVALID_REFERENCE naming the step and the event (X19) - Status names a missing or older root Vitest before any start (X9, EN11) - Help, instructions and descriptions carry the API 1.8 sentences, the example, walkthrough, results, refusals and limits;

Stop during an advance, during the report check and during the result write settles before the seal; a signal and an exit 0 without a report; a release retried after a failure seals complete; coverage grows from the cache without store reads and the history resource agrees;

charset=UTF-8 Content-Transfer-Encoding: 8bit - NodeLearningSave (EN14): the status item's states for a test run (preparing, live with the stop count, finished, saving, saved, partially saved, stop rejected, read after the seal failed, seal failed), the question before the result, the composed partial-save notification, Retry per stage and receipts by material revision; StudyWorkspace only wires its item and commands to it - Open replay routes a test replay to openNodeHistoryFromHost: the Study pane opens when closed, a browser replay is closed first by the learner's choice, a failed open raises the load-failure notification and an Output entry; the pane's node-history message and the host open share openNodeHistory under one request counter (EN19), landing on the first verified stop without a saved position (DS1) - Saved studies rows read 'Test replay · · capture … · k of m stops explained'; the Application pane shows the interim sentence; the Study pane's 'replay unavailable' sentences are gone - One 'Codebook' LogOutputChannel receives the service's and the workspace's diagnostics - Workspace tests that start at a history's first event pin that position;

Subject: [PATCH 07/25] Tests for Open replay of test replays, EN9 ownership,
 Saved studies rows and Output entries

- studyWorkspaceTestReplay: Open replay in a closed Study pane lands on the first verified stop, a saved
  position wins, an unverified stop lands on the first event, a browser replay refuses with one
  notification, an unreadable history raises the load-failure notification and an Output entry, and a
  pane open during a host open wins with a double click showing one replay
- studyWorkspaceRemoval: refreshes after the background selection changed leave a selected test replay's
  source and debugger on its stop (red without the EN9 guard)
- describeNodeTestReplay: Saved studies rows, the interim Application sentence, the Output entry format

Subject: [PATCH 08/25] C49-7: skill 1.0.46 routes test questions to node-test
 and claims saved learning only with complete coverage

A request about a test, or about library behavior a test exercises, uses the
node-test profile and its help; a test stop is explained in chat, never
through codebook_explain, whose paragraphs now name the browser profile; an
error before the first stop is a refusal at preparation; saved learning is
claimed only with studyOutcome demonstrated and nodeTest.learningCoverage
complete; a failing test is named as such; the learner opens the test replay
from the status bar. Seven pins read the bundled skill (six fail on 1.0.45).

 Follow the public Codebook help/resources and the returned current state to select only the tools needed for the request. If this chat cannot open a returned MCP resource URI, use `codebook_read_resource` with that exact URI. When relevant, inspect source, operate the application, pause execution, read actual values, explain the relationship, continue from the **current** run state using its returned arguments, and save or replay a recording. Do not invent stop locations, values or repository-specific steps.
 
+**Test runs.** A request about a test, or about library behavior a test exercises, uses the `node-test` profile and its public help. After the start, read the run until its first stop or its `error`: a run that ends with an `error` before its first stop was refused at preparation, so follow that error's fix, then start again with a new key. At each test stop, explain in chat from that stop's captured facts and continue with the run's current arguments; do not call `codebook_explain`, which belongs to the browser profile and refuses a test stop. After the result, save the learning with `codebook_explain_node_history` and read the saved material back. Claim saved learning only when the run resource reads `studyOutcome` `demonstrated` and `nodeTest.learningCoverage` `complete`; a run resource without `nodeTest.learningCoverage` supports no such claim. When `nodeTest.testResult` is `failed` or `signal`, say that the test did not pass, name its exit code or signal, and say that the replay holds the failing run. Tell the learner that **Save learning replay** and **Open replay** are in the status bar; the learner opens the test replay (`codebook_playback` controls browser recordings only).
+
 Publishing an immutable source article supplies the citations needed by a managed run. `codebook_open_book` opens the separate repository reader; it is not a preparation step for `codebook_start`. For a live request, use source reads to check citations and keep the Study app/source layout in place. Open the repository reader when the learner asks to read the article, or after the live run, because its native tabs can change the Study layout receipt.
 
 If Study asks for focus or layout recovery, use its existing pane, the `codebook_presentation` focus/restore actions with fresh identity, or the visible **Restore Study workspace layout** control. Do not call `codebook_open_book` to create a focusable pane or repair Study; that opens the independent Wiki reader and can introduce a foreign editor tab. If the current editor groups contain unrelated tabs, preserve them and report the resulting manual-layout prerequisite.

 Read the selected profile's supported configuration versions before declaring ordered stops. Version 1 keeps browser stops within one citation. Version 2 binds each stop to its own participant, source and article citation; choose the sequence and useful required inspections from the actual requested path. A pending server breakpoint is registration only: require a committed pause with verified executed source before claiming observed values. One input drives the sequence; explain each pause, then copy the currently paused participant's continuation arguments without sending another click. Chronological stops alone do not prove a cross-runtime causal link.
 
-For each committed pause in a runtime explanation request, read its returned `inspectionUri` and source, then save the grounded explanation with `codebook_explain` using the public tool contract. Wait for the committed explanation receipt before continuing. Writing an explanation in chat does not save it to Study or recording. When the request concerns visible behavior, read the observation’s returned `imageUri` (immutable for that pause), or the returned phase image for a legacy single-stop run and describe their actual pixels; capture metadata alone is not an image inspection. Preserve observed facts, source-based interpretation and unknowns as separate claims.

 Before starting a new run with an open presentation, read `presentation.reader.followingCurrentRun` and `presentation.reader.contentTab`. If following is `false` or the content tab is not `live`, use `codebook_return_current` with the current reader revision. Verify both `followingCurrentRun: true` and `contentTab: live` before starting, so pauses show captured values and saved explanations instead of the source-only Overview. This only changes the selected view; do not repeat an application action to recover the reader.

 After stopping a run, read its current run resource until history and recording receipts settle. Claim a saved study only when `studyOutcome` is `demonstrated`, and claim a replayable recording only when `recordedStudyOutcome` is `demonstrated`; `finalOutcome` alone describes runtime evidence, not durable storage. Before claiming replay of explanations, follow the recording's returned `learningUri` (use `contextUri` only for full raw history) and verify that each observed pause retains its interpretation. Report any missing interpretation, storage limit or failed receipt even if the click, pause and screen checks succeeded.
 
-For saved learning, include `learningSummary` in `codebook_explain` after inspecting the relevant snapshots and sources. Preserve the learner question, summarize the processing path, and name participants and ordered interactions. Classify each step as `observed`, `source-derived` or `unknown`; attach the exact same-run snapshot URI and source hash to observed/source-derived source steps. A source reference supports inspection, not proof that an inferred interaction executed. Leave uncaptured behavior explicitly unknown at that point in the recording. After the run is stopped and its result demonstrated, read its `terminalReference`. If present, author a new complete summary through `codebook_explain` with a new explanation key and an observed final-result step citing that exact reference. Use a committed snapshot and its captured fact paths for the explanation call; the terminal reference supports only the final result step. Preserve the earlier pause's uncertainty and describe the result as later verification. Wait for the new explanation and matching saved-history/recording receipts before claiming the replay contains the revised summary. Older recordings may have no saved summary.

 When linking an observed moment in a later article revision, copy `studyId` from that run's resource and `observationId` from its `observations[].id`. The runtime session ID inside a pause or artifact path is a different identity and cannot locate the saved Study archive. Publish the link only after the run's saved history is confirmed; retry a failed publication with a new key only after correcting its input.

 # Changelog
 
+## [0.2.33.0] - 2026-10-22 (development candidate)
+
+Cycle 0049 is a feature cycle ([Issue #107](https://github.com/laststance/codebook/issues/107)): a Vitest test run that the editor chat explained becomes a learning replay, a **test replay**. It is delivered in three pull requests, merged in order; this version holds the first, the loop and its contracts. The recorded test output in the Application pane and the summary's selected step come with the second, the recorded source with its transitions and the native round in both editors with the third.
+
+**A test run becomes a test replay.**
+
+- **Ask about a test.** Ask `/codebook` in Copilot Chat or Cursor Agent about a test, or about library behavior a test exercises. The chat starts a `node-test` run of that test with the Vitest at the repository root, pauses at the stops it declared, explains each from its captured values in the chat and continues to the result.
+- **Save learning replay.** While the run records, the status bar reads `Recording explanation · stop  of  · Save learning replay` (before its first stop, `Preparing the test run…`). Saving before the result asks first, because it ends the run. Save seals the test history and reads the chat's learning material: `Learning saved · Open replay` when the test passed, every stop's recorded debugger state verifies and the material explains every stop and the result; otherwise `Learning partially saved · Open replay`, whose tooltip names the result and what is missing and whose notification says what to ask the chat for, or that only a new run records it. A failing test's replay is saved too. A failed save says which stage failed (stopping the run, sealing the history, reading it back) and what its button does.
+- **Open replay.** Open replay, and a test replay's row in Saved studies, open it in the Study pane at its saved reader position, or on its first stop whose recorded source verifies: its test output, the executed source and the native debugger's recorded values and stack at each stop; no application video. During a browser replay Codebook says that one replay shows at a time, with **Close browser replay**.
+- **Saved studies** name each test replay's result, capture and explained stops, for example `Test replay · Test passed · exit code 0 · capture complete · 2 of 2 stops explained`. The sentences that called a test history's replay or application video unavailable are gone; until the second pull request the Application pane says that the recorded output is in the Study pane.
+- **Output › Codebook.** An unexpected failure on these paths writes one entry with the surface, the study, the profile, the versions, the cause and the stack. A cause shown anywhere names the extension's storage, the workspace and the home folder as ``, `` and `~`.
+
+**For the agent (MCP API 1.8).** A node-test run reads `demonstrated` in `finalOutcome` once its test passed after every declared stop, and in `studyOutcome` and `recordedStudyOutcome` once its history sealed complete; before, it read `partial` at most. Its run resource adds `nodeTest.testResult` (`passed`, `failed`, `signal` or `none`), `nodeTest.learningCoverage` (`complete`, `partial` or `none`) and `nodeTest.learningMissing`, and `nextActions` lists `save-node-learning` until the coverage is complete; the node-history resource reports the same three fields. A node-test start's checks (a changed stop source, a changed test file, a path that is not a file, a root Vitest missing or older than 4) run during preparation and end the run with a typed `error` before its first stop, which records no history and frees the run's slot and key; `codebook_status` names a missing or older root Vitest before any start. `codebook_stop` answers `HISTORY_SEAL_FAILED` when it could not seal the history of the run it ended, `codebook_playback` refuses a test replay with `PLAYBACK_PROFILE_UNSUPPORTED`, and `codebook_explain_node_history` refuses a step that cites another event than it claims with `INVALID_REFERENCE`, naming what that event is. The node-test help gains a complete example, the ordered walkthrough of the calls and the root-Vitest limit. A test that ends with a non-zero exit code or a signal keeps that result even without Vitest's report, and a passing run whose first release failed seals complete once a retried Stop releases it.
+
+**Compatibility.** The MCP API is 1.8. The bundled skill is 1.0.46: it routes a question about a test to the node-test profile, has the chat explain a test stop in the chat (never through `codebook_explain`, which belongs to the browser profile), reads an error before the first stop as a refusal at preparation, claims saved learning only with `studyOutcome` `demonstrated` and `nodeTest.learningCoverage` `complete`, names a failing test as such and points the learner to Save learning replay and Open replay. No stored format changes: test histories, learning materials and reader positions written by 0.2.32.0 open unchanged, and those written now open in 0.2.32.0.
+
+**Not observed.** Cursor, Windows and Linux: this pull request's native pilot runs in VS Code on macOS (its result is in the Issue). The skill's sentences are pinned by tests; only a model run shows a chat following them.
+
 ## [0.2.32.0] - 2026-10-21 (development candidate)
 
 Cycle 0048 is a bug-fix cycle with no increment ([Issue #105](https://github.com/laststance/codebook/issues/105)). It holds the 24 defects that the adversarial review of Cycle 0047's final candidate found, 5 that the archived test guide carried, and the 189 found while it ran: 218 tasks, and its delivery closes every one. It is the fifth cycle under the rule that every defect a cycle leaves is fixed in the next one, and the first whose Issue holds its tasks and state. Most changes are in the skill's Wiki publisher, the Wiki reader and the test runners.

 ## Implementation status
 
-This is a preview, not a Marketplace or Open VSX release. The delivered version is **0.2.32.0** once [PR #106](https://github.com/laststance/codebook/pull/106) is merged; until then 0.2.31.1 is the delivered one and 0.2.32.0 the candidate that pull request holds, and the active cycle Issue says where the delivery stands. It is the delivery of [Cycle 0048](https://github.com/laststance/codebook/issues/105): a bug-fix cycle with no increment that closes the 24 defects the adversarial review of Cycle 0047's final candidate found, 5 that an archived test guide carried, and the 189 found while it ran. Most of them are in the Wiki and the test runners: the skill's publisher syncs every file of a publish before its swap, keeps the learner's files with their mode and times, and works when it is started through a linked folder; the reader refuses a request for another host; Delete asks first when the record of a recording's writer cannot be read; and a test call that stays silent is ended and named. The MCP API stays 1.7. The proof that a natural `/codebook` request reaches its observed result on its first admitted run is still owed and belongs to the frozen request of the feature cycle that follows. What each earlier cycle delivered, with its tests, trials and limits, is in the [change history](CHANGELOG.md) and in that cycle's record, kept under the tag [`docs-archive-2026-10-20`](https://github.com/laststance/codebook/tree/docs-archive-2026-10-20/docs/cycles); from Cycle 0048 on, the cycle's Issue holds its tasks and state, and its pull request its results.

The MCP API is 1.8. The recorded test output in the Application pane and the summary's selected step come with its second pull request, the recorded source with its transitions and the native round in both editors with its third; the test replay's summary in the Learning summary view is the next feature cycle.

+- **Preparing the test run…** until the run records its first stop; there is nothing to save yet.
+- `Recording explanation · stop  of  · Save learning replay` while the run records. Saving before the test's result asks first (`Saving ends the test run before its result ( of  stops reached). Save now?`), because it ends the run.
+- **Recording finished · Save learning replay** once the run has ended: Save reads the sealed history and the chat's learning material.
+- **Learning saved · Open replay** when the test passed, every stop's recorded debugger state verifies, and the learning material explains every stop and the result.
+- **Learning partially saved · Open replay** otherwise. The tooltip names the result and every missing part, and a notification says what to ask the chat for (a missing explanation) or that only a new test run records it (missing capture). A failing test's replay is saved too: it holds the failing run.
+- **Learning save failed · Retry** when stopping the run did not finish (Retry stops it again) or the sealed history could not be read back (Retry reads it again; the test does not run again), and **Learning save failed · Open retained history** when the history could not be sealed (the recorded part opens read-only). Each tooltip names the cause; the details are in **Output › Codebook**.
+
+**Open replay**, or the test replay's row in Saved studies, opens it in the Study pane at its saved reader position, or on its first stop whose recorded source verifies. 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`. In this version the recorded output shows in the Study pane, and the Application pane points there.
+
+#### Quick start: a test replay
+
+1. Open the repository in VS Code or Cursor and run **Codebook: Set Up AI Chat** once. The repository needs Vitest 4 or later installed at its root.
+2. In Copilot Chat or Cursor Agent, ask `/codebook` your own question about a test, or about library behavior a test exercises.
+3. Follow the chat: it pauses the test at the stops it chose and explains each from the captured values, which you can inspect in the native debugger meanwhile.
+4. When the test has run, click **Save learning replay** in the status bar.
+5. Click **Open replay**, or open the test replay from Saved studies, and step through its stops, its output and its result.
+
+#### Terms
+
+- **Learning replay**: a saved explained run that you can replay after it ended; a browser run's holds the application video.
+- **Test replay**: the learning replay of a test run: its test output, the executed source and the debugger's recorded stops; no application video.
+- **Study pane**: Codebook's reader beside the editor, with Saved studies, a replay's summary and its controls.
+- **Application pane**: the pane that shows the recorded application of a browser replay.
+- **Stop**: a place in source where the run paused for the explanation, numbered in the order the run reached it.
+- **Saved studies**: the list of saved replays in the Study pane.

 ## LLM Wiki: open and update
 
 **Codebook: Open DeepWiki in Browser** serves the generated site from a loopback reader in your browser. The reader answers only on this computer: a request whose Host is its own loopback address, or any loopback address the editor has forwarded it to (each stays accepted if the editor forwards it again). A window whose forward goes to another host (a tunnel, a browser-based editor) gets no page, only a 403 that says so. The reader removes the effect of a page's own `referrerpolicy` attributes and `` element, so a Wiki page cannot send the reader's private address to another site. **Update LLM Wiki** (the button in the right rail of that page, or **Codebook: Update LLM Wiki** in the Command Palette) asks the editor agent to regenerate the site. The button asks for confirmation in the editor first; in VS Code the confirmation says where the request goes: `Copilot Chat receives the update request for this project in a new chat; the chat you have open keeps its place in the chat list. If the Chat view has not been opened in this window yet, the request may go into the chat it restores. A draft you typed into an empty chat is replaced by the request; a draft in a chat with messages stays with that chat.` The command starts at once and asks nothing: its request goes into a new chat in the same way (into the chat the Chat view restores, if that view opens only now) and replaces a draft in an empty chat in the same way; the Chat view shows the chat with the request. When the watch ends and what to do after you refused a step of the chat are in the row **Updating LLM Wiki…** below. The page then shows the run and its result under the button without a reload; the site stays readable the whole time.

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.

API 1.8 changed what a `node-test` run reports: it reads `demonstrated` in `finalOutcome` once its test passed after every declared stop, and in `studyOutcome` and `recordedStudyOutcome` once its history sealed complete (before, it read `partial` at most); its run resource adds `nodeTest.testResult` (`passed`, `failed`, `signal` or `none`), `nodeTest.learningCoverage` (`complete`, `partial` or `none`) and `nodeTest.learningMissing`, and `nextActions` lists `save-node-learning` until the coverage is complete. A node-test start's checks run during preparation and end the run with a typed `error` before its first stop, `codebook_stop` answers `HISTORY_SEAL_FAILED` when it could not seal the history of the run it ended, and `codebook_playback` refuses a test replay with `PLAYBACK_PROFILE_UNSUPPORTED`. 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.

Subject: [PATCH 10/25] Tests for the browser recording's seal-failure channel
 and Open retained history

codebook_stop answers HISTORY_SEAL_FAILED when a browser run's recording cannot
be finished at its stop, the same for a repeated stop with no second finish,
and nothing for a study the learner removed (each red without its guard);
Open retained history opens a test history whose seal failed as an interrupted
prefix on its recorded stop.

Subject: [PATCH 11/25] Activation keeps working where the service or the
 window API is a stand-in

a1e47eb pushed the extension's storage folder into the service's
extraStorageRoots array and created the Output channel through
vscode.window without a guard: a service without that array threw before the
server started, and a host without a window API threw at activation. The
extension now assigns extraStorageRoots, as it assigns the service's other
collaborators, and creates the channel only where the window API exists.
Red before: 20 tests of editorChatOnboarding and extension (one of which then
hung its file until it was ended).

Subject: [PATCH 14/25] The node-test help's start example names its key as a
 placeholder; a test title says API 1.8

The pre-gate's credential scan read the example's key: 'explain-delayed-job-1'
as a secret-named assignment and cannot be downgraded; the start key is the
agent's own choice, so the example now shows '' like
its other placeholders (the example still parses as a start). The configured
discovery test asserts API 1.8 and its title now says so (pre-gate literals).

Subject: [PATCH 15/25] F1: the four macOS-only test failures were test
 isolation; each test now names the system it describes

Three boot-identity tests describe a system without a kernel boot id (Windows,
or the Linux their start inputs name) but read the boot for the system the test
ran on: on macOS readBootIdentity then reads the real kern.bootsessionuuid and
the record carries an id the test does not expect. They now pass the platform
they describe to readBootIdentity and currentStorageOwner. The recording-store
lock test refused unlink only for '/writer.lock', while the store names
its lock under the directory's real path (/private/var on macOS), so the refusal
never applied; the test now builds the lock path from realpath(directory).
Red before on macOS (4 of 47 in the three files), green after; Linux unchanged.
No product code changes. Unblocks the /ship pre-gate on macOS, which refuses
publication while a lane fails (PREGATE_LANE_FAILED, not downgradable).
