fix(auto-approval): match symlinked workspace roots - #2454
Part of #1948. Supersedes #2041, which was automatically closed for author inactivity. This PR does not close#1948.
Description
Read allowlists now recognize both the lexical and verified canonical paths of the task workspace root. This fixes approval matching when the workspace root is a symlink. The change supports the Reliability First roadmap goal.
Each ordered rule checks both root paths before the next rule runs. Absolute wildcard exclusions and later re-inclusions keep their order. Workspace names with brackets, stars, question marks, or POSIX backslashes stay literal. They cannot widen a grant to neighboring directories.
Windows candidates, patterns, and roots use the same path conversion. Explicit UNC paths remain separate from drives and rooted paths without a known volume. A rooted path in a UNC workspace resolves against that network share. The inherited server and share names are escaped as literal names for both grants and exclusions. User-authored globs in explicit UNC patterns keep their meaning.
UNC parsing requires exactly two leading separators and nonempty server and share names. Repeated separators between the server and share remain supported. Three or more leading separators retain Windows rooted-path semantics, so ///server/share/docs/** cannot grant access to //server/share/docs/private.md. Workspace roots resolve .. using Windows path rules before conversion to matcher paths. Parent traversal stops at the drive or share root and cannot create an alias for another share.
When the Windows workspace has no known drive letter, rooted exclusions retain their reach over explicitly granted drive paths. For example, ["C:/**", "!/**/.env"] excludes C:/x/.env with a UNC workspace, a drive-less workspace, or no workspace. A later explicit rule can re-include the file. Rooted grants remain scoped to the workspace volume, and the internal UNC and unknown-root prefixes remain isolated.
Only the workspace root uses realpath. The matcher does not resolve individual file aliases. Unknown or unresolvable roots retain lexical matching. Resolution failures are logged. Read and write allowlists retain separate exclusions. Canonical root equivalence applies only to reads. Protected-file policy remains in effect.
Intentional Windows hardening: The shared matcher rejects drive-relative candidates and patterns, including bare drive designators. These paths depend on per-drive process state that the matcher cannot safely infer. A drive-relative workspace root also rejects relative candidates and rules, even if realpath succeeds. This applies to reads and writes. Explicit absolute grants remain usable, with ordered exclusions. The previous behavior could approve an absolute file outside the actual workspace.
Literal question marks use standard backslash escaping with the current ignore dependency. Regression assertions reject neighboring directory names ending in 1, x, 3, or f.
Test Procedure
Environment: Node 22.23.1, pnpm 10.8.1, macOS. The branch contains three commits on main f2b4d1c0d.
pnpm check-types
pnpm test
pnpm knip
pnpm knip:production
pnpm test:knip-policy
Full monorepo tests passed: 14/14 Turbo tasks. The extension suite passed 13,158 tests, with 39 skipped.
Full type checks passed: 12/12 Turbo tasks.
Scoped ESLint pruning passed. The suppression file remained byte-for-byte unchanged.
Both Knip modes and all 8 Knip policy tests passed.
Regression coverage includes UNC separator handling, workspace-root parent traversal, literal roots, ordered exclusions, drive boundaries, and a real symlink/junction integration. It also covers rooted exclusions, literal inherited UNC names, canonical drive aliases, independent read/write allowlists, later re-inclusions, and protected writes.
The Windows-default matcher harness checked Windows path behavior. Native Windows CI must validate the final commit.
Scope: The changes cover workspace-root approval matching and its path-safety constraints.
Self-Review: Reviewed the update and its regression assertions.
Writing Style: The title and description use short sentences and plain words.
Testing: Regression tests and the full monorepo suite passed.
Test Helpers: Scenario-specific payloads and assertions remain visible.
Documentation Impact: Checked the impact. No user-facing documentation update is required.

Additional Notes
This is an independently mergeable prerequisite for the reader-safety work in #1999. Merge this prerequisite first, then rebase the reader-safety branch onto main.
Review history remains available in #2041. GitHub does not let the author reopen that PR after the bot closed it.
Recognize lexical and verified canonical workspace-root spellings without resolving individual file aliases. Preserve ordered grants, exclusions, literal root names, and lexical-parent rules across POSIX, Windows drives, and UNC shares.
Reject ambiguous Windows drive-relative inputs without widening read or write permissions. Centralize platform selection in WorkspaceRootStrategy.forPlatform and cover literal UNC share names with regression tests.
Resolve them on the pull request, or post @coderabbitai approve as a new top-level comment to resolve them and request approval.

Summary
Summary by CodeRabbit
Bug Fixes
Improved file-pattern matching for automatic approvals across POSIX and Windows paths, including drive-relative paths, UNC shares, and workspace roots that resolve through symlinks.
Workspace-relative permissions now distinguish files inside the workspace from similarly named paths outside it, including when workspace-root resolution fails.
Exclusion and re-inclusion rules are applied consistently across equivalent path spellings while preserving rule order and separate read and write permissions.
Windows path matching now handles volume roots, repeated separators, and case differences more consistently.
Auto-approval now uses platform-specific path strategies and matches paths across lexical and canonical workspace roots. Read approval resolves the workspace root asynchronously and checks each named file against configured patterns.
Changes: Workspace root-aware matching

Merge Risk: Low · up to cd46b
On Windows with a UNC workspace, an exclusion written with three leading slashes may not take effect against drive-letter paths. A file the user meant to exclude could then be auto-approved. This is a narrow edge case with a small fix, so it should be addressed before or shortly after merge.

Full details: Title check
Explanation
The title "fix(auto-approval): match symlinked workspace roots" names the main change: read-allowlist matching now checks both the lexical and canonical (realpath-verified) workspace root, which fixes approvals when the workspace root is a symlink. The title is short, specific, and in the repository's conventional-commit style. The large Windows path-handling and UNC work in the changeset is broader than the title, but the title does not misrepresent it.
Full details: Description check
Explanation
The description follows the repository template in structure. It includes Related GitHub Issue, Description, Test Procedure, Pre-Submission Checklist, Visual Snapshots, Videos, Documentation Updates, Additional Notes, and Get in Touch. It explains the how, the Windows hardening trade-offs, and the reviewer-relevant constraints, and it lists the test commands and results. Two points need attention. First, the issue link is weak: it references the prerequisite of #1948 and states that it does not close that issue, and the template requires every PR to link to an approved issue. The PR also supersedes #2041, which was closed automatically, so the approval status of the linked issue is unclear. Second, the Description and Test Procedure sections are dense and use some non-STE phrasing (for example, 'retain their reach', 'remain isolated', and sentences with several clauses). The checklist also marks items as complete that the reviewer should verify, such as the Writing Style and Scope items, given the PR's breadth across Windows, UNC, and read/write logic.
Resolution
Optional improvements: confirm that the linked prerequisite issue #1948 is approved, since the template requires an approved issue link. Consider splitting the Windows hardening notes and test details into shorter sentences to match the Simplified Technical English guidance. Re-check the Scope checklist item, because the change set covers both POSIX and Windows matcher behavior.
Full details: Out of Scope Changes check
Explanation
The changed code matches the PR's stated scope: workspace-root approval matching for read and write allowlists. The changes include canonical workspace-root equivalence for reads, ordered exclusions and re-inclusions, literal root characters, UNC and drive boundary handling, and Windows drive-relative rejection. The PR description discloses the Windows drive-relative rejection as intentional hardening. The description also states that protected-file policy and separate read and write exclusions remain in effect. The related tests (for example workspaceRootSafety.integration, windowsPaths, windowsRootedApproval, and workspaceRootEquivalence) check these same behaviors. The batch-read requirements of #1948 depend on per-file approval correctness, so this matcher work supports that link. No changed file in the raw summary is unrelated to approval path safety. Limitation: the raw summary is AI-generated and was not checked against the full diff. The tests were not run during this assessment.
Full details: Persistence Integrity
Explanation
The check fails only for a changed persistence path that can lose or corrupt state through an un-awaited operation, a non-atomic write, missing rollback or partial-failure handling, or an unpropagated persisted default. The changed production files are path-matching and approval logic under src/core/auto-approval/: WorkspaceRootCanonicalizer.ts, filePatterns.ts, index.ts, and the new strategy classes. Scanning the added production lines for writeFile, appendFile, rename, unlink, rm, globalState, workspaceState, .update(, and persistence or settings writes found no production write path. The only write-like calls (fs.writeFile, fs.mkdtemp, fs.rm) appear in test files that create and remove temporary fixtures. The one async change in production code is in index.ts. isReadAllowedByPatterns becomes async and calls realpath through resolveCanonicalWorkspaceRoot. The caller now uses await isReadAllowedByPatterns(...), so the new promise is awaited. The realpath failure path catches the error and returns undefined, which falls back to lexical matching. This is a read-only check and does not persist state. No changed path writes, persists, or defaults stored state. The check therefore does not apply to this PR, and I found no failure condition in it.
Full details: Lifecycle Resource Cleanup
Explanation
The check fails only when a changed lifecycle path can leak a listener, watcher, provider, timer, task, or other resource, or duplicate work after cancellation, disposal, or restart. The only changed lifecycle-adjacent code is in src/core/auto-approval/index.ts. The diff adds resolveCanonicalWorkspaceRoot, which makes one realpath(cwd) call. It is awaited inside isReadAllowedByPatterns, which now returns a Promise, and checkAutoApproval awaits that result. This path does not create a listener, watcher, timer, provider, or task. It holds no handle that needs cleanup. A realpath call that finishes after a cancellation returns a value and does no further work. The early return on empty allowlists also avoids the call when it is not needed. A search of the non-test changed sources under src/core/auto-approval/ found no setTimeout, setInterval, .on(, addListener, watch, dispose, subscribe, abort, signal, or cancel usage. The remaining matches were the realpath import, its call, and a doc comment. The CodeRabbit threads cover path-matching security (UNC and drive-root handling). They do not describe resource leaks or duplicate work, so they do not meet this check's condition.
Full details: Linked Issues check
Explanation
[#1948] Directly linked issue #1948 requests a bounded native multi-file read tool. It requires per-file parameters, batch and aggregate output limits, per-entry results (success, error, denial, truncation, budget exhaustion, cancellation), independent approval per file, image-limit and format checks, strict-schema compatibility, and tests for schema, execution, permissions/UI, ordering, budgeting, cancellation, and the Codex single-call path. The changed files in the raw summary (WorkspaceRootCanonicalizer, WorkspaceRootStrategy and its Posix/Windows subclasses, filePatterns.ts, auto-approval/index.ts, and their tests) implement workspace-root approval matching only. They add no batch read tool, batch schema, per-entry result model, batch execution path, or UI path. The approval matching changes support one part of the requirement, which is that every named file must match an allowlist. They do not implement the tool. The PR description states that it does not close #1948, but the issue remains a directly linked target. The unmet coding requirements therefore remain open. The raw summary does not show any change since the previous review that adds batch-read code, so the previous FAIL remains supported.
Resolution
Either (a) implement the #1948 requirements in this PR: add the bounded native multi-file read tool with per-file parameters, per-entry outcomes, batch and aggregate output bounds, independent approval per file, provider compatibility for single-tool-call providers, and tests for parsing, execution, approvals/UI, compatibility, and provider behavior; or (b) change the link so that #1948 is recorded as contextual or partial background for this prerequisite, not as a directly linked coding target. Under option (b), the batch-read acceptance criteria no longer apply to this PR.
Full details: Security Boundaries
Explanation
The changed matcher in src/core/auto-approval/filePatterns.ts (isFileMatchedByPatterns, head lines 473-478) still leaves a configured rooted exclusion ineffective for drive paths. The standing prior failure is upheld. Evidence: - The guard at line 475 is unchanged at head: if (rootedExclusion.startsWith("/") && !rootedExclusion.startsWith("//")). The drive-compatibility fallback (driveCandidates, lines 460-463, 473-478) is new in this PR. The base revision has no driveCandidates or rootedExclusion code. - For !///**/.env, the guard is false, so the fallback is never added. The primary matcher maps the pattern into the workspace volume namespace (for example /UNC/server/share/**/.env or /ROOT/**/.env, via WindowsWorkspaceRootStrategy.toMatcherAbsolutePath). That namespace does not match the drive candidate C/x/.env. - The PR description says three or more leading separators keep rooted-path semantics. It also says rooted exclusions keep their reach over drive paths in drive-less or UNC workspaces, for example ["C:/**", "!/**/.env"]. The triple-slash spelling falls outside that stated behavior. - Plausible scenario: a UNC or drive-less workspace with ["C:/**", "!///**/.env"], candidate C:/x/.env. The grant C:/** matches, and the configured .env exclusion does not apply. readFile can return approval for a file the user excluded. - No test covers !///**/.env. Existing rooted-exclusion tests use !/**/.env (windowsPaths.spec.ts lines 113-131 and 133-160; windowsRootedApproval.spec.ts). - The CodeRabbit thread on filePatterns.ts line 475 remains unresolved, and its suggested fix is not applied. Limits: - I could not execute the ignore library or the matcher in this sandbox. The conclusion rests on reading the head code. - I did not establish whether the base revision honored !///**/.env for drive paths. The trigger is an unusual spelling, so the impact is narrow. The defect is still in changed code that governs an exclusion control. Other prior threads (WindowsWorkspaceRootStrategy UNC and share-boundary issues) are marked addressed. Their head code matches that claim on inspection, and they do not change this verdict.
Resolution
In src/core/auto-approval/filePatterns.ts, change the guard at line 475 so that three or more leading separators still create the drive-compatibility alternative. Keep the two-slash UNC spelling excluded. For example, test !/^\/\/[^/]/.test(rootedExclusion) and collapse leading slashes with .replace(/^\/+/, "/") before adding the alternative. 2. Add a regression test in windowsPaths.spec.ts or windowsRootedApproval.spec.ts. Use a UNC or drive-less workspace, patterns ["C:/**", "!///**/.env"], and candidate C:/x/.env. Expect isFileMatchedByPatterns to return false and readFile to return ask. 3. Keep the existing !/**/.env cases passing. Keep the two-slash UNC behavior unchanged.
Full details: Regression Evidence
Explanation
Regression evidence is incomplete for the rooted-exclusion branch in isFileMatchedByPatterns. Changed behavior: src/core/auto-approval/filePatterns.ts lines 473-478 add a drive-candidate alternative for rooted negated patterns. The guard at line 475 is rootedExclusion.startsWith("/") && !rootedExclusion.startsWith("//"). Three-slash spellings such as !///**/.env therefore skip the drive alternative. The guard is unchanged in the current tree, and the PR's diff touches this block. Evidence gap: - A search for !/// in src/core/auto-approval/__tests__ returns no matches. - Triple-slash tests cover grants only (windowsPaths.spec.ts lines 34-52; windowsRootedApproval.spec.ts line 46). - Negated cases exist only for !/**/.env (windowsPaths.spec.ts lines 117-152; windowsRootedApproval.spec.ts lines 67, 126, 148-155). This is a changed negative branch in an exclusion rule. No test covers it. The untested branch is the one a triple-slash exclusion takes. The open CodeRabbit thread on this line (discussion unresolved, code unconfirmed) reports that ["C:/**", "!///**/.env"] with a UNC workspace leaves C:/x/.env approved. I did not execute tests. The structural reading of the guard supports that report. Other changed behaviors (canonicalizer, strategies, realpath failures, symlink integration, and the two-slash and single-slash exclusion cases) have focused coverage. The gap is limited to this branch. Prior failure: the standing FAIL remains. Its claims are confirmed. The guard still excludes triple-slash, and no !/// test exists. Neither required fix has landed.
Resolution
In src/core/auto-approval/__tests__/windowsPaths.spec.ts, beside the !/**/.env cases (lines 117-152), add a test. Use a UNC or drive-less workspace, patterns ["C:/**", "!///**/.env"], and candidate C:/x/.env. Expect false. Also assert that a later explicit grant re-includes the file. 2. In src/core/auto-approval/filePatterns.ts line 475, change the guard so three or more leading separators reach the drive-candidate alternative. Keep the two-slash UNC spelling excluded. Collapse leading separators before the alternative is added. The CodeRabbit suggested diff is one option. 3. Confirm the new test fails before fix 2 and passes after it. 4. Resolve the open review thread on filePatterns.ts line 475 only after the test and fix land.

Allow triple-slash rooted exclusions to use the drive-compatibility fallback.
!///**/.env fails the startsWith("//") guard, so its drive-candidate alternative is never added. With cwd: "//server/share/ws", the file C:/x/.env, and patterns ["C:/**", "!///**/.env"], the exclusion does not apply. The C:/** grant then matches, and the file can be auto-approved. The single-slash form !/**/.env is excluded.
Three leading separators do not form a UNC root. Node's win32 path handling requires a non-empty server segment, a separator, and a non-empty share name. WINDOWS_UNC_PREFIX also requires a non-separator server name. toMatcherAbsolutePath already collapses leading separators for rooted paths, so the guard should follow the same rule.
Change the guard to skip only the two-slash spelling. Collapse leading separators before adding the rooted alternative:

// Apply each rule to both spellings BEFORE advancing to the next rule.
Two-slash spellings keep their current behavior. Add the !///**/.env case to the cross-volume exclusion tests beside !/**/.env.

Review comment at @src/core/auto-approval/filePatterns.ts at line 475:
Update the rootedExclusion guard and alternative construction so triple-or-more leading separators are treated as rooted paths, while preserving the existing behavior for two-slash UNC spellings. Collapse leading separators to one before adding the rooted alternative to alternatives with driveCandidates, and add the !///**/.env cross-volume exclusion case alongside the existing !/**/.env coverage.

Part of #1948. Supersedes #2041, which was automatically closed for author inactivity. This PR does not close #1948.
Description
Read allowlists now recognize both the lexical and verified canonical paths of the task workspace root. This fixes approval matching when the workspace root is a symlink. The change supports the Reliability First roadmap goal.
Each ordered rule checks both root paths before the next rule runs. Absolute wildcard exclusions and later re-inclusions keep their order. Workspace names with brackets, stars, question marks, or POSIX backslashes stay literal. They cannot widen a grant to neighboring directories.
Windows candidates, patterns, and roots use the same path conversion. Explicit UNC paths remain separate from drives and rooted paths without a known volume. A rooted path in a UNC workspace resolves against that network share. The inherited server and share names are escaped as literal names for both grants and exclusions. User-authored globs in explicit UNC patterns keep their meaning.
UNC parsing requires exactly two leading separators and nonempty server and share names. Repeated separators between the server and share remain supported. Three or more leading separators retain Windows rooted-path semantics, so
///server/share/docs/**cannot grant access to//server/share/docs/private.md. Workspace roots resolve..using Windows path rules before conversion to matcher paths. Parent traversal stops at the drive or share root and cannot create an alias for another share.When the Windows workspace has no known drive letter, rooted exclusions retain their reach over explicitly granted drive paths. For example,
["C:/**", "!/**/.env"]excludesC:/x/.envwith a UNC workspace, a drive-less workspace, or no workspace. A later explicit rule can re-include the file. Rooted grants remain scoped to the workspace volume, and the internal UNC and unknown-root prefixes remain isolated.Only the workspace root uses realpath. The matcher does not resolve individual file aliases. Unknown or unresolvable roots retain lexical matching. Resolution failures are logged. Read and write allowlists retain separate exclusions. Canonical root equivalence applies only to reads. Protected-file policy remains in effect.
Intentional Windows hardening: The shared matcher rejects drive-relative candidates and patterns, including bare drive designators. These paths depend on per-drive process state that the matcher cannot safely infer. A drive-relative workspace root also rejects relative candidates and rules, even if realpath succeeds. This applies to reads and writes. Explicit absolute grants remain usable, with ordered exclusions. The previous behavior could approve an absolute file outside the actual workspace.

Environment: Node 22.23.1, pnpm 10.8.1, macOS. The branch contains three commits on main
f2b4d1c0d.pnpm check-types pnpm test pnpm knip pnpm knip:production pnpm test:knip-policyRegression coverage includes UNC separator handling, workspace-root parent traversal, literal roots, ordered exclusions, drive boundaries, and a real symlink/junction integration. It also covers rooted exclusions, literal inherited UNC names, canonical drive aliases, independent read/write allowlists, later re-inclusions, and protected writes.
The Windows-default matcher harness checked Windows path behavior. Native Windows CI must validate the final commit.
