Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk:🟡 Moderate · up to This PR adds per-step change cards and persisted detail settings to file-write flows. At the current head, some writes can still complete without a checkpoint or change card, and a multi-file patch can leave earlier writes without recovery coverage when a later file is denied; users could lose rollback and audit visibility, so these paths need explicit handling or acceptance before merge. A minor Dutch localization issue also remains. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@src/core/checkpoints/__tests__/changeCard.spec.ts`:
- Around line 88-93: Update the parsed change-card payload variables in
buildChangeCardPayload tests, including the additional referenced cases, to use
the shared ChangeCardData type imported from `@roo-code/types` instead of
duplicated local shapes or broad string detail types. Preserve the existing
payload assertions and behavior while aligning every parsed card with the
maintained schema.
In `@src/core/checkpoints/__tests__/checkpointJournal.test.ts`:
- Around line 65-76: Complete the ProviderLike and TaskLike test doubles used by
checkpointSave by adding getState and say members, then initialize them in the
setup with a resolved getState mock returning an empty object and a resolved say
mock so successful tests follow the normal path after the journal append.
In `@src/core/task/Task.ts`:
- Around line 2499-2506: Update the task-start baseline call in Task’s
checkpoint flow to invoke checkpointSave with true as its first argument and
preserve true as the second argument, ensuring a baseline is recorded even for a
clean workspace. Update the matching test expectation to assert
checkpointSave(true, true).
In `@src/core/tools/ApplyPatchTool.ts`:
- Around line 179-206: Update ApplyPatchTool’s patch-result handling to persist
successfulChanges whenever it is nonempty, even when a later hunk fails or is
rejected; flush them before any subsequent early-return paths so checkpoint,
journal, and change-card records are created for already-written files. Preserve
the existing perWriteCheckpoints behavior and metadata mapping, and add a
regression test at the lowest failing layer covering a successful hunk followed
by a failed or rejected hunk.
In `@webview-ui/src/context/ExtensionStateContext.tsx`:
- Around line 214-215: Wire changeCardDetail through CheckpointSettings.tsx and
SettingsView.handleSubmit(): bind the control to local cachedState, allow
selecting the existing “summary” and “full” values, and include the cached value
in the updateSettings payload. Ensure the full selection survives the save/load
round trip and add coverage for that behavior.
In `@webview-ui/src/i18n/locales/hi/settings.json`:
- Around line 706-711: Update the checkpoint setting’s label and description in
the locale resource, correcting the malformed Hindi terms to the reviewed forms
“लिखने,” “चेकपॉइंट,” “स्नैपशॉट,” and “किया जाता है,” while preserving the
existing meaning and keys.
In `@webview-ui/src/i18n/locales/ja/settings.json`:
- Around line 705-707: Replace the malformed Japanese label and description
under the perWrite localization key with natural Japanese translations that
accurately describe recording a checkpoint snapshot after each successful agent
file write.
In `@webview-ui/src/i18n/locales/ko/settings.json`:
- Around line 705-707: Replace the malformed Korean values for the perWrite
label and description with natural, accurate Korean translations while
preserving the existing settings structure and keys.
In `@webview-ui/src/i18n/locales/nl/settings.json`:
- Around line 709-711: Update the Dutch description for the changeCardDetail
setting so the clause describing disabled behavior uses grammatical sentence
structure while preserving its meaning: cards should show only the file list
with added and removed lines when the option is disabled.
In `@webview-ui/src/i18n/locales/pl/settings.json`:
- Around line 705-711: Update both label and description values in the perWrite
translation to replace “każłdym” with “każdym”, and revise the changeCardDetail
description so “Wyłączone, karty” becomes a complete Polish sentence.
In `@webview-ui/src/i18n/locales/pt-BR/settings.json`:
- Around line 709-711: Update the description value in the changeCardDetail
translation so the disabled-state sentence explicitly states the condition,
replacing the grammatically incorrect “Desativado, os cartões mostram” phrasing
while preserving the existing meaning.
In `@webview-ui/src/i18n/locales/ru/settings.json`:
- Around line 705-708: Update the description value in the perWrite translation
object to use the grammatically correct Russian phrase “после каждой успешной
записи файла,” preserving the rest of the label and description.
In `@webview-ui/src/i18n/locales/vi/settings.json`:
- Around line 705-708: Update the description under the perWrite setting to
replace the misspelled Vietnamese phrase “ánh chắc điểm kiểm tra” with the
correct snapshot terminology, such as “ảnh chụp nhanh điểm kiểm tra,” while
preserving the rest of the translation.
In `@webview-ui/src/i18n/locales/zh-TW/settings.json`:
- Around line 732-735: Update the perWrite label and description values to use
Traditional Chinese characters consistently, replacing simplified forms such as
写、査、会、个 with their Traditional equivalents while preserving the existing
meaning.

If an earlier hunk writes a file and a later
validateAccess()call returns false, Line 135 returns before the post-loop checkpoint code. The written file then has no checkpoint, journal entry, or change card.Set
patchSucceededto false and break the loop instead of returning. This preserves the recorded successful subset.Proposed fix
if (!accessAllowed) { await task.say("rooignore_error", relPath) pushToolResult(formatResponse.rooIgnoreError(relPath)) - return+ patchSucceeded = false+ break }Add a regression with one successful hunk followed by an access-denied hunk. As per coding guidelines, “For regressions, add the test at the lowest layer that would have failed.”

Part of the file-write-safety series (#1375) — B3a: per-step change cards + the changeCardDetail setting (extension host). Stacked on B2.
Scope note: the planned B3a (cards + rollback + setting) measured 1484 changed lines — over the series' 1000-line hard cap — so, per the plan's budget rule, it splits into sequential sub-PRs: this PR ships the cards + setting; the rollback service ships as a stacked follow-up (#1410), and the webview UI (settings control, card rendering, rollback buttons) ships as B3b.
