fix(mentions): restrict expansion to authorized user input - #2421
Mention expansion reads local files and other resources. Before this change, a forged <user_message> tag in generated text could authorize expansion.
Each message now carries typed segments. A segment has text and a source, either user or generated. Only user segments expand @ mentions.
The extension and the webview both track the source of each part of the text. Missing, invalid, or mismatched segments fail closed. The text is then treated as all generated.
Changes by boundary:
Task start, resume, follow-up answers, and completion feedback expand user segments only.
Add-to-context, enhanced prompts, and generated editor and terminal prompts carry generated segments.
Queued messages, queue edits, and prompt history keep each segment source.
Edited messages expand nothing, because stored messages carry no segments.
Test Procedure
Run these commands:
pnpm --dir src exec vitest run to test the extension.
pnpm --dir webview-ui exec vitest run to test the webview.
pnpm --dir src exec tsc --noEmit and the same in webview-ui to check types.
The tests cover accepted and rejected segments through every entry point. They also cover mixed-origin text, queue edits, prompt history, and the resume path.
Pre-Submission Checklist
The change follows the project guidelines.
Tests cover the change.
ESLint suppression counts did not increase.
No changeset or CHANGELOG entry was added.
No user-facing documentation update is needed.
Notes
Edited messages and recalled prompt history no longer expand user-typed mentions. A follow-up must store segments with user_feedback messages to restore this.

Summary
Summary by CodeRabbit
Bug Fixes
Mentions and image mentions are processed only in explicitly entered text; generated context and tool results are left unchanged.
Follow-up answers and completion feedback preserve the distinction between entered text and generated content.
Code and terminal actions keep entered text separate from generated context.
Editing a message preserves the origin of unchanged text and marks edited portions as user-entered.
Text origin is preserved when messages are queued, sent, edited, or restored from prompt history.
The change adds typed user and generated text segments and carries them through chat, webview, task, and queue flows. Mention parsing and image-mention resolution use user-authored segments. Generated text and tool-result content are not parsed as user input.
Changes: Authorized Mention Segments
Layer / File(s)
Summary
Define and transform mention segments packages/types/src/message.ts, packages/types/src/vscode-extension-host.ts, src/shared/mentionSegments.ts, src/shared/support-prompt.ts, src/shared/__tests__/*
MentionSegment records text and a user or generated source. Helpers validate, join, trim, and edit segments. Support prompts separate userInput from generated template text.
Track segment origins in chat webview-ui/src/components/chat/ChatView.tsx, webview-ui/src/components/chat/ChatTextArea.tsx, webview-ui/src/components/chat/hooks/usePromptHistory.ts, webview-ui/src/components/chat/__tests__/*
Chat input preserves segment origins across edits, generated insertions, suggestions, sending, and queueing. Prompt history saves and restores draft segments. Enhanced prompts use the generated-text setter.
Carry segments through webview and queue src/core/webview/ClineProvider.ts, src/core/webview/webviewMessageHandler.ts, src/core/message-queue/MessageQueueService.ts, src/extension/api.ts, src/core/webview/__tests__/*, src/core/message-queue/__tests__/*, src/extension/__tests__/*
Webview messages, extension API calls, and queued messages carry segments. Image resolution scans user-segment text. Queue edits preserve unchanged segment sources and mark changed text as user-authored.
Process authorized task and feedback text src/core/mentions/processUserContentMentions.ts, src/core/task/Task.ts, src/core/tools/AskFollowupQuestionTool.ts, src/core/tools/AttemptCompletionTool.ts, src/core/mentions/__tests__/*, src/core/task/__tests__/*, src/core/tools/__tests__/*, src/core/assistant-message/__tests__/presentAssistantMessage-images.spec.ts, src/eslint-suppressions.json
Task input and responses retain segment metadata. Mention processing checks recorded block identity and matching text, then parses only user segments. Follow-up and completion feedback use segmented user-message blocks. Tests cover authorization, feedback processing, and message ordering.

Merge Risk: Low · previous review b7930
Mention expansion now fails closed and only user-typed text expands, which is the intended security fix. One narrow gap remains: feedback given when resuming a pending action is not expanded, so mentions in it are sent as literal text. The remaining review comment asks for a resume-button test of generated feedback. Merging is low risk.

Explanation
The title "fix(mentions): restrict expansion to authorized user input" matches the main change. The PR replaces the earlier substring-based authorization with typed mention segments labeled user or generated, and only user segments expand @ mentions. The title is short, specific, and in the imperative style.

Explanation
The description follows the repository template in substance. It links the issue (Closes: #2461), describes the how and the trade-offs (typed segments, fail-closed handling, per-boundary behavior), gives test commands, and completes the checklist. It omits the Visual Snapshots and Videos sections, which do not apply to this non-visual change, and it does not state a Discord username in Get in Touch. Those are non-critical gaps.
Full details: Out of Scope Changes check
Explanation
The changed areas map to #2461 or support it:
Segment types, schema, and helpers (packages/types/src/message.ts, src/shared/mentionSegments.ts, src/shared/support-prompt.ts createSegments) implement the typed segment model.
Extension entry points (Task.ts, AskFollowupQuestionTool.ts, AttemptCompletionTool.ts, ClineProvider.ts, webviewMessageHandler.ts, api.ts, MessageQueueService.ts) carry segments through the flows the issue names.
Webview files (ChatView.tsx, ChatTextArea.tsx, usePromptHistory.ts) track source for drafts, edits, suggestions, enhanced prompts, and prompt history. The issue names these flows.
Removal of text-marker detection and tool_result parsing in processUserContentMentions.ts follows from the issue requirement to stop authorizing text by markers.
presentAssistantMessage-images.spec.ts changes follow from feedback text becoming a separate user block.
The eslint-suppressions.json removal follows from the rewritten processUserContentMentions.spec.ts.
No change lacks a connection to #2461.
Full details: Regression Evidence
Explanation
The PR changes mention-expansion authorization from a substring approach to typed user/generated segments. I checked the changed behaviors against the test files added or updated in the same PR. Coverage is focused and includes negative and fail-closed cases. - Segment helpers (src/shared/mentionSegments.ts):src/shared/__tests__/mentionSegments.spec.ts covers normalizeSegments for valid input, plus omitted, non-list, invalid-source, text-mismatch, and empty-text inputs. It also covers applyEdit for insert, middle insert, delete, replace, all-user text, mismatched old value, and unrelated edits. trimSegments and userText are covered too. - Expansion gate (src/core/mentions/processUserContentMentions.ts): The processing logic is covered by processUserContentMentions.spec.ts. Per the summary, the spec covers wrapped user messages, copied or modified blocks, tool results left unexpanded, and parser flags. Task.persistence.spec.ts adds resume-path tests: "expands only the user segments of an interleaved answer" and cases for generated, invalid, omitted, or mismatched segments. - Entry points: Tests exist for the task start, follow-up (askFollowupQuestionTool.spec.ts, including the null answer), completion feedback (attemptCompletionTool.spec.ts), and queued messages (MessageQueueService.spec.ts, including the no-segment case). Also covered are the newTask, askResponse, queueMessage, and edit paths in webviewMessageHandler.newTask.spec.ts, the headless API in api-send-message.spec.ts, and startNewTask in api-start-new-task.spec.ts. - Webview:ChatView.spec.tsx, ChatView.add-to-context-authorization.spec.tsx, ChatView.clear-approval-buttons.spec.tsx, and ChatTextArea.spec.tsx cover segment-carrying sends, manual edits, generated enhanced prompts, and history restore with segments. - Playwright snapshot condition: The webview-ui diff has no markup, class, or layout changes. The UI changes are logic and wiring only. The Playwright snapshot requirement therefore does not apply. I did not find a concrete changed behavior that lacks focused coverage. Tests were not executed, because build tooling is unavailable in this sandbox. This verdict rests on static inspection of the test names and bodies.
Full details: Security Boundaries
Explanation
The changed code narrows mention expansion. It does not add a new trust path for unvalidated input. Evidence: - src/shared/mentionSegments.tsnormalizeSegments checks incoming segments with the mentionSegmentSchema zod schema. It also requires the joined segment text to equal the message text. Otherwise it returns one generated segment, so the path fails closed. - webviewMessageHandler.ts builds segments with segmentsOf for newTask, askResponse, and queueMessage. It also builds them with generatedSegments for editMessageConfirm. Image scanning now uses only userText(segments), so generated text attaches no images. - Task.tssubmitUserMessage, the ask-response path, and the new-task path call normalizeSegments before userMentionContent/wrapUserMessage. AskFollowupQuestionTool.ts and AttemptCompletionTool.ts also normalize before expansion. handleQueuedAskResponse forwards unnormalized message.segments, but every consumer normalizes them. - processUserContentMentions.ts expands only user segments of blocks registered in an in-memory WeakMap. The old path expanded any text containing <user_message>, including tool_result content. The new path removes that trigger, so a forged tag in generated text no longer authorizes expansion. Tool results pass through unchanged. - api.ts marks text from the programmatic startNewTask and sendMessage APIs as user. Before this PR, that text was wrapped in <user_message> and expanded anyway, so this does not widen access. No changed path leaks secrets or PII. No changed path runs unvalidated input. No changed path bypasses approval or allowlist controls. The diff reduces the mention-expansion surface.
Full details: Persistence Integrity
Explanation
The PR adds typed mention segments (user or generated) to the chat, queue, and task flows. It does not change any persistence write path. I checked the changed-file list and the diffs for Task.ts, MessageQueueService.ts, processUserContentMentions.ts, and the webview handlers. None of them changes saveApiMessages, saveClineMessages, task-history updates, globalState, or file writes. The only queue-related change is in MessageQueueService.addMessage and updateMessage. Those edits are in memory. The queue emits stateChanged and has no disk write. Its claim, release, and remove calls (claimNextMessage, releaseMessage, removeMessage) are unchanged in the diff. The await parseMentions calls in processUserContentMentions.ts remain inside the await Promise.all(...) block. The new segments field in queuedMessageSchema is optional. It is not written to durable storage in the changed code. No changed persistence path matches the failure conditions: an unawaited operation, a non-atomic write, missing rollback, or an unpropagated persisted default.
Full details: Lifecycle Resource Cleanup
Explanation
The check fails only when a changed lifecycle path can leak a listener, watcher, provider, timer, or task, or can duplicate work after cancellation, disposal, or restart. I inspected the full PR range (base to head) for lifecycle-related additions in non-test code. - No added lines in non-test source use addEventListener, setTimeout, setInterval, subscribe, watchers, .on(/.once(, AbortController, or new new Promise resolvers. The only match for the broader pattern was an import line for useEffect, which already existed. - The only new keyed container is a WeakMap in processUserContentMentions.ts, which holds entries keyed by object identity. The PR removes the earlier authorizedMentionText path. Its lifetime is GC-bound and does not pin resources. - Task.ts: askResponseSegments is set in handleWebviewAskResponse and read and cleared in the same result block as askResponseText and askResponseImages in ask(). This follows the existing pattern. The finally block that clears timeouts is unchanged. - ChatTextArea.tsx: the message-listener effect still returns removeEventListener. Its dependency list gained setInputValueProgrammatic. That value comes from useCallback with stable deps, so the listener does not churn. programmaticInsertRef is a boolean flag. It can remain set if execCommand emits no input event. That affects which setter the next edit uses. It does not hold a resource, and it is not a leak or duplicated-work path under this check. - MessageQueueService, api.ts, usePromptHistory.ts, and ChatView.tsx add state or setters only. They add no subscriptions or timers. The queued-message drain change passes segments into an existing submitUserMessage call with its existing .catch. No changed path creates a leak or post-cancellation duplicate work, so the check passes.
Full details: Linked Issues check
Explanation
Directly linked issue #2461 is open and has coding requirements. Most are met. Evidence from the reviewed head (b793021):
Typed segments { text, source: "user" | "generated" } exist in packages/types/src/message.ts. Normalization in src/shared/mentionSegments.ts falls back to all-generated text when segments are missing, invalid, or mismatched. Requirements 1 and 4 are met.
Segments flow through newTask, askResponse, queueMessage, edit confirm, and submitUserMessage (webviewMessageHandler.ts, Task.ts, api.ts, MessageQueueService.ts, webview). Requirement 3 is met.
authorizedMentionText is removed. Requirement 5 is partly met.
Image mention scans use user-authored segments in webviewMessageHandler.ts. Requirement 6 is met.
Tests cover accept and reject paths across entry points. Requirement 7 is met by inspection of test summaries; tests were not run.
Unmet requirement: #2461 item 5 and Acceptance require removing the WeakMap in processUserContentMentions. The reviewed file src/core/mentions/processUserContentMentions.ts still declares const segmentedBlocks = new WeakMap<TextPart, { text: string; segments: MentionSegment[] }>(). userMentionContent stores each block's segments in this map, and the processor reads them back by block identity. This side table is the mechanism the issue asks to remove. It also keeps a second place where provenance is matched to text (labeled.text === block.text).
Limitation (not a failure by itself): edited messages expand no user-typed mentions, because edit-box text is marked generated. The author documents this trade-off. The issue acceptance criteria concern authorization, so this does not fail a stated requirement.
Resolution
Remove the segmentedBlocks WeakMap from src/core/mentions/processUserContentMentions.ts. Carry the segments on the value passed to the processor instead. For example, define a typed content part or an explicit input field that holds MentionSegment[], and have processUserContentMentions read segments from that field. Keep the fail-closed behavior: a block with no segments, or with segments that do not match its text, is treated as all generated. Then update the tests in processUserContentMentions.spec.ts and the callers of userMentionContent to match.

Resolve a mutation gap
Add or strengthen a focused test that fails under the mutation. If the mutant is equivalent, request maintainer approval for the narrowest mutator-specific exclusion and explain why it cannot change behavior:
// Stryker disable next-line ConditionalExpression: normalized input cannot reach the alternate branch
const result = condition ? value : fallback
Broad all exclusions and exclusions without a concrete reason are reported as advisories.
Reproduce locally
From a full checkout containing both commits:
pnpm install --frozen-lockfile

- Use `it.each` for repeated cases and share the setup in a helper. Do not copy a test body per input.
The named approval, denial and mistake-feedback paths did not add the marker required for ordinary mention expansion before this PR. The inspected queued-message paths do not establish another previously supported expansion path that was missed.

Authorize live feedback when resuming a pending action.
If the user rejects a restored pending action with @/allowed, this path places the feedback only inside a tool_result. The new mention processor always skips tool results, so this newly supplied feedback cannot expand its mention.
Append a separate userMentionContent block for the original feedback, as the follow-up and completion tools now do. Preserve the tool result and add a focused pending-action resume regression test.

- Regression Evidence:
Add focused tests in `src/core/task/__tests__/` for the changed task boundaries:
1. Root task start: construct a task with no `authorizedMentionText` and no
parent. Run `startTask` and assert that the first user block is authorized and
expands only the task text. Use the existing `initiateTaskLoop` spy to read the
content. 2. Child task start: construct a task with `parentTask` set and no
`authorizedMentionText`. Assert that the task text is not expanded. This is the
negative branch. 3. Explicit `authorizedMentionText`: construct a task with the
option set. Assert that only that input expands, and that the surrounding
`<user_message>` wrapper stays intact. 4. Resume feedback: call
`resumeTaskFromHistory` with a non-empty response text. Pass the resulting
content through `processUserContentMentions` and assert that the response input
expands. Add a negative case with an empty response. Each test should fail if
the `userMentionContent` call or the `authorizedMentionText` fallback expression
is removed or inverted.

## Test Placement Guidance
- Use `it.each` for repeated cases and share the setup in a helper. Do not copy a test body per input.
- Add authorizedMentionText to the setChatBoxMessage and newTask webview
messages. The webview tracks the user-authored substring and clears it
when the user edits the box.
- webviewMessageHandler fails closed when the webview omits the field.
- Task start no longer authorizes the full task text by default. The API
start passes its own text as authorized.
- Cover the handler forwarding, the task start boundary, and the chat box
flow with tests.

ClineProvider.delegateParentAndOpenChild passes a parent and a model-written child message; Task.startTask does not authorize that message by default when parentTask exists. For history-only tasks, Task.run invokes Task.resumeTaskFromHistory, which separately authorizes newly supplied responseText. Check both paths when changing authorization.

723-724: Security & Privacy
The concern that image mentions bypass the authorization gate is not supported by the code it cites. Line 714 of src/core/webview/webviewMessageHandler.ts does not call resolveImageMentions. The newTask branch (lines 709-738) forwards the normalized authorization field to provider.createTask without a prior image resolution step. The only call in the file occurs at line 234, in a different handler that reads the webview payload text. The comment does not establish that this path receives generated or unauthorized text, so its premise is refuted.
- Carry authorizedMentionText through askResponse and queueMessage, the
host handler, stored ask responses, and queued messages.
- Follow-up answers, completion feedback, resume feedback, and drained
queued responses authorize only that substring. Absent values fail
closed to an empty string.
- Treat an omitted setChatBoxMessage field as authorizing nothing from
the inserted text.
- Route enhanced prompt and insert updates through a programmatic setter
that preserves the recorded authorization scope.
- Type the new test doubles without any or never casts and strengthen
the task start tests with a distinct substring case.

## ESLint Suppressions
### Typed test files
New or substantially changed test files must not add `typescript-eslint/no-explicit-any` suppression entries to `src/eslint-suppressions.json`:
- Prefer typed structural doubles: type mock context/proxy classes against the real public types they stand in for (e.g. `vscode.ExtensionContext`), and use `unknown` for storage values and mock callback parameters instead of `any`.
- Access private members with bracket notation (`provider["view"]`) and call public members without casts so their generic signatures keep checking arguments.
- When a partial double cannot be assigned to the real type, cast it once at the construction site (`as unknown as T`) with a comment naming the members the double provides; do not repeat `as any` at every use site.
- Validate with `pnpm --dir src run check-types`, the narrowest affected Vitest suite, and `pnpm --dir src exec eslint --prune-suppressions --max-warnings=0 <relative-test-...

1922-1922: Preserving a null scope still authorizes generated replacements.
If the user types a prompt, authorizedMentionRef.current is null. An enhancedPrompt replacement uses this raw setter and leaves the ref unchanged. The next send therefore authorizes the entire generated replacement, including generated mentions.
Before a programmatic update, convert unrestricted authorization into the previous user-authored text. Preserve restricted strings without widening them. Cover enhancement after ordinary typing, not only after an explicitly unauthorized insertion.
799-803: Carry authorization through the explicit queue controls.
If the user queues @/chosen.txt with the queue button, this payload omits authorizedMentionText. The host now defaults the missing field to "", so the mention does not expand when consumed. The imperative command_output queue path at Line 1674 has the same omission.
Forward the recorded scope through both paths and clear it with the draft. These paths must match the updated Enter-to-queue path.
Scan only the authorized substring for image mentions. Pass the stored
scope through queued messages and submitUserMessage. Fail closed when
a prompt enhancement replaces typed text or a suggestion is sent.

Preserve restricted authorization when appending a suggestion.
If the draft is empty or manually typed, authorizedMentionRef.current is null. Shift-clicking a suggestion containing @/secret appends model text without changing that scope. Sending without another edit then authorizes the entire value, including the suggestion's mention.
Record the prior draft's authorization before appending. Use the generated-text setter rather than the raw setter. Add local Vitest cases for empty and manually typed drafts.
Based on learnings, “copying or appending a suggestion must not authorize its mentions” until a manual edit.

Authorize the edited text when a checkpoint restore replays the pending edit.
The non-checkpoint edit path authorizes the edit-box text. The checkpoint path stores editedContent without a scope. When the task is recreated, handleWebviewAskResponse receives no fourth argument, so authorizedMentionText defaults to "". Mentions such as @/file in the edited message are not expanded when checkpoint restoration is selected. The model receives the literal mention text.
The edit box holds only user-typed text, so the replayed editedContent can be authorized in full:

2645-2645: Security & Privacy
The mechanism is established, but the comment's trigger is not. The branch authorizes the whole message.text. The edit path loads that text and can confirm it without a change. Whether a generated editor or terminal prompt containing a mention can become a stored, editable user message is not decided by the inspected sources. Until that producer is inspected, the claim that generated text reaches this branch remains undecided.
…d substring
Messages now carry segments with a source of user or generated. The
extension expands mentions per user segment and never searches the text
again. The chat box records manual edits as user text with a diff, so
typing near generated context does not authorize it. Enhanced prompts,

segments fail closed.
Reworked in 2fa2bc1 (follows issue #2461). The authorizedMentionText substring is gone. Messages now carry segments with a source of user or generated. The extension expands mentions per user segment and never searches the text again. The chat box records each manual edit as user text with a diff, so typing near generated context does not authorize it. Enhanced prompts, suggestions, and model text stay generated. Missing or mismatched segments fail closed. This replaces the earlier fixes for image scans, queue, edit, suggestions, and trim.

Forward user provenance on the launched-webview sendMessage path.
When viewLaunched is true, API.sendMessage posts the text without segments. ChatView normalizes the missing field to generated segments, so the text is not treated as user input. Mentions in API-supplied text, such as Read @/instructions.md, are then not expanded. The headless branch already labels this text as user input with userSegments(text ?? "").
Add the same segments to the launched-webview message:

Pass the edited message's segments through the pending-edit replay.
The replay calls handleWebviewAskResponse without segments. The handler stores undefined. The consumer then passes it to normalizeSegments, which returns all-generated text. Mentions typed into the edited message do not expand after the restore. The pending-edit record must keep the segments, and the replay must forward them.
The fix also requires a segments?: MentionSegment[] field on PendingEditOperation. The write site must populate it from the edit's segments.

Preserve mention segments for feedback on restored pending actions.
When a user answers a restored create_subtask ask with @/instructions.md, ask() returns the user segments, but this destructuring discards them. Lines 3531–3537 place the feedback only in a tool_result. The changed mention processor passes tool results through unchanged, so the authorized file mention no longer expands.
Capture segments from both asks in this method. Add a separate authorized feedback block after the tool result, as the follow-up tool does. Add a regression test for this restored-action path.

# AGENTS.md
## Test Placement Guidance
- Use `it.each` for repeated cases and share the setup in a helper. Do not copy a test body per input.
73-73: Preserve generated text between separate edits.
For generated text ctx @/secret.txt, saving Please ctx @/secret.txt ! makes applyEdit mark the entire message as user text. Neither end matches, so the inferred replacement includes the unchanged mention. Dequeue normalization accepts these segments because their text matches.
The unchanged-save and append tests do not cover this case. Preserve provenance through individual edit operations rather than infer all edits from one final-value replacement.
43-43: Data Integrity & Integration
The queued answer keeps its segments through the ask result.
handleQueuedAskResponse passes message.segments into handleWebviewAskResponse. That method stores them in askResponseSegments, and ask() returns them in the result. A queued user segment such as @/allowed.txt therefore reaches the ask result. The reported loss does not occur on this path.
252-252: Complete the previously requested mixed-origin assertions.
The test checks parser inputs but discards the processed content. It still passes if processing drops @/secret after parsing @/mine. The rejection cases also lack output assertions.
Capture the result and assert the complete content in both tests. Add the previously requested user/generated/user fixture to check that expansion resumes after generated text.
As per path instructions, “For tests that assert only mock call counts, confirm a corresponding return-value assertion exists.” This remains part of the supplied previous review comment.
1222-1222: Assert the processed feedback for every table row.
The parser-input assertion does not detect dropped or altered feedback. Capture processUserContentMentions’s result and assert the complete content for the mixed-origin and rejected rows. Use user/generated/user segments to verify both authorized portions.
As per path instructions, collection tests must use mixed input that “asserts the full output array.” This remains part of the supplied previous review request covering both tools.
Assert the full processed output for user, generated, user segments in both tools.
Add resumeTaskFromHistory tests for accept, omitted, mismatched, and empty responses.

cover a matching answer with user/generated/user segments containing mentions;
assert the exact parser inputs and preserved response block so segment sources
remain significant. Add rejection cases for matching generated-only and
invalid-source segments, keeping the coverage scoped to resume.

- Regression Evidence:
Add a focused unit test in `src/extension/__tests__/api-send-message.spec.ts`.
Set `viewLaunched: false` and mock `getCurrentTask` to return an object with a
`submitUserMessage` spy. Assert that `api.sendMessage("see @/file.ts", images)`
passes the text, images, `undefined`, `undefined`, and `[{ text: "see
@/file.ts", source: "user" }]`. Assert the forwarded segments for empty or
missing text. Assert that the no-task branch logs and returns without calling
`submitUserMessage`.

Require regression coverage at the lowest valid harness with behavior-focused assertions, including relevant negative, error, false/unset, and boundary cases.
The sendMessage API and the approve and reject feedback now carry user
segments, so typed mentions expand as in the headless path. Add tests for
queued answers, edit overlap, and mention processing.
Approve, reject, resume and queue sends now use one helper. The helper
checks that the segments match the text. Tests cover generated text and
the resume_task ask.

Remove the `segmentedBlocks` WeakMap from
src/core/mentions/processUserContentMentions.ts. Carry the segments on the value
passed to the processor instead. For example, define a typed content part or an
explicit input field that holds `MentionSegment[]`, and have
`processUserContentMentions` read segments from that field. Keep the fail-closed
behavior: a block with no segments, or with segments that do not match its text,
is treated as all generated. Then update the tests in
processUserContentMentions.spec.ts and the callers of `userMentionContent` to
match.

Source excerpt: **Patch Gate (`target: 70%`)**: New or modified lines in PRs touching `webview-ui/src/` must meet minimum test coverage, ensuring state changes and new UI logic stay tested over time.
The claim that extension-supplied primaryButtonClick or secondaryButtonClick feedback can authorize @ mention expansion is not supported by the inspected code. Both producers in the repository send the invoke without text. Nonempty feedback on these invokes does not occur in the inspected code, so the null-provenance path in segmentsFor is not reached with user-like text from any producer found.
The positive matrix includes resume_task, but this matrix exercises only command. A resume-only regression that marks generated feedback as user would pass these added tests. Add a resume_task case and assert the exact generated segment after clicking Resume. The resume handler has a separate payload construction path. (raw.githubusercontent.com)
As per path instructions, “require tests for both the accept path and the reject path through every public entry point.”

Closes: #2461
Description
Mention expansion reads local files and other resources. Before this change, a forged
<user_message>tag in generated text could authorize expansion.Each message now carries typed segments. A segment has text and a source, either
userorgenerated. Onlyusersegments expand@mentions.The extension and the webview both track the source of each part of the text. Missing, invalid, or mismatched segments fail closed. The text is then treated as all generated.

Test Procedure
Run these commands:
pnpm --dir src exec vitest runto test the extension.pnpm --dir webview-ui exec vitest runto test the webview.pnpm --dir src exec tsc --noEmitand the same inwebview-uito check types.The tests cover accepted and rejected segments through every entry point. They also cover mixed-origin text, queue edits, prompt history, and the resume path.
Pre-Submission Checklist
Notes
Edited messages and recalled prompt history no longer expand user-typed mentions. A follow-up must store segments with
user_feedbackmessages to restore this.
