* fix(skills): build readme_url from the resolved source directory

For skills.sh installs, `skill.directory` is just the skillId (the
innermost directory name) and the search-result readme_url is the bare
repo URL, so the persisted doc link lost the real nested path
(e.g. skills/developertools/solutions/<name>) and 404'd (#6111).

- install: derive the doc path from the resolved source directory
  (repo-relative, SKILL.md-anchored) ahead of the stale readme_url
  extraction and the directory-name fallback.
- update_skill: same derivation, so records written by older versions
  self-heal on the next update instead of re-assembling the broken
  path from the stale readme_url. repo_branch already follows
  used_branch.
- New choose_doc_path / doc_path_for_source helpers with regression
  tests; dropping the resolved-path priority fails the tests.

668bbda916 perf(backup): batch dump INSERTs and restore preserved tables in one transaction (#6122)
* perf(backup): batch dump INSERTs and restore preserved tables in one transaction

Backup import was pathologically slow for databases with large log
tables. Measured on a database with 26k log rows (Windows, debug build):

- local file import (import_sql_string): 28.0s -> 0.39s (~71x)
- WebDAV/S3 sync import (import_sql_string_for_sync): 118.9s -> 0.33s
  (~360x)
- export: 367ms/15.4MB -> 193ms/3.9MB (column list no longer repeated
  per row)

Root causes, isolated with a phase-level benchmark (kept in the test
suite as ignored perf harnesses):

1. dump_sql emitted one INSERT statement per row. The restore side
   parses/prepares/finalizes every statement individually, so import
   cost scaled with statement count, not data volume. A control run on
   an in-memory database was equally slow, proving this is CPU-bound
   parsing, not disk I/O; journal/synchronous pragmas made no
   difference. dump_sql now emits multi-row VALUES batches of 200 rows
   (~200x fewer statements; SQLite has supported multi-row VALUES since
   3.7.11, and both old and new formats import through the same generic
   execute_batch, so dumps remain cross-version compatible).

2. restore_tables re-inserted preserved local tables (proxy logs,
   stream check logs, usage rollups) with one implicit autocommit
   transaction per row against the disk-backed staging database - one
   fsync per row, ~4.6ms each on Windows. All restores now run in a
   single transaction with the INSERT prepared once per table, which
   also makes a mid-restore failure roll back atomically instead of
   leaving a half-restored table.

Regression tests:
- dump_sql_batches_rows_into_multi_row_inserts pins the batch shape
  (450 rows -> exactly 3 INSERT statements; fails if reverted to
  per-row)
- multi_row_dump_round_trips_special_values round-trips quotes,
  newlines, commas, CJK, emoji, BLOB storage class, and NULL through
  export+import
- existing authorizer / genuine-export / sync-preserve tests still pass

zayokaandClaude Fable 5 6b8f36431b fix(security): cap scripts, file reads, and proxy bodies; surface deeplink usage fields (#5919)
* fix(security): harden usage script execution and Grok session log collection

Three hardening fixes in v3.19.0 code:

1. **usage_script: cap JS runtime resources and execution time**
   `execute_usage_script` used a vanilla `Runtime::new()` with no limits,
   so a malicious or buggy script delivered via deeplink or synced DB could
   hang the backend thread forever with `while(true)`. Add
   `create_script_runtime()` enforcing a 5-second interrupt handler, 16 MiB
   memory limit, and 256 KiB stack limit. Regression test confirms an
   infinite-loop script is rejected within seconds instead of blocking.

2. **Grok session log: skip oversized files**
   `sync_single_grok_file` loaded the entire `updates.jsonl` into memory
   with no size cap. Add a 50 MiB limit and skip files that exceed it.

3. **Grok session log: bound directory traversal**
   `collect_files_named` recursed without depth limits and followed
   symlinks, so a symlink cycle under `~/.grok/sessions` caused a stack
   overflow. Add a 16-level depth limit and skip symlinks entirely.

* fix(ui): show hidden usage access token and user id in deeplink provider import dialog

The provider import confirmation dialog parsed usageAccessToken and
usageUserId from ccswitch:// URLs and persisted them in
ProviderMeta.usage_script, but never rendered them. Users could not see
these credentials before approving the import.

- Add i18n keys for usageAccessToken/usageUserId in all locales.
- Render both fields in the usage script section; mask the access token
  like usageApiKey.
- Add a regression test verifying the dialog displays the masked token
  and the user id.

* fix(security): bound Codex model catalog and proxy response bodies

Two issues were found while auditing security boundaries:

1. **Codex model_catalog_json arbitrary file read**
    only checked the filename and
   accepted any absolute path. A malicious  could
   point CC Switch at an external file (e.g. ) or a huge
   file to exhaust memory.

   - Require the resolved path to stay inside
     using a new  helper (lexical, no filesystem calls).
   - Treat Unix-style absolute paths as absolute on Windows.
   - Cap catalog reads at 32 MiB.

2. **Unbounded proxy response bodies / compression bombs**
   Non-streaming responses and error responses were read with
    and fully decompressed without any byte
   limit, allowing a malicious upstream to OOM the backend.

   - Add  with a 128 MiB ceiling.
   - Reject oversized bodies and oversized decompressed payloads with
     .
   - Map the new error variant into the Codex proxy error response.

Regression tests cover: absolute-path containment, traversal rejection,
oversized catalog file, oversized buffered/streamed proxy responses.

* fix(ci): set up pnpm via Corepack instead of pnpm/action-setup v6

pnpm/action-setup v6 installs pnpm through a two-step self-installer:
it bootstraps the latest pnpm (11.7.0) via npm, then downloads the
pinned version (10.12.3) from the npm registry to switch. When that
second tarball fetch failed (error 23), the self-installer still
reported "done" and crashed with ENOENT on @pnpm/linux-x64's
package.json, failing the CI setup step.

Replace the action with Node 20's bundled Corepack and pin the version
once via package.json's packageManager field, so setup performs a
single exact-version download with no floating bootstrap. This also
lets release.yml drop its Windows ARM64 special case, since Corepack
has no arch restrictions, and pins the same version for local dev.

* fix(security): close review gaps in proxy body caps, deeplink dialog, catalog path

Address maintainer review on the security PR:

- Proxy: bound the four remaining unbounded forwarder read paths
  (non-2xx error body, failover pre-read, both 2xx error-envelope
  validators) with bytes_with_limit + bounded decompression.
- Proxy: bytes_with_limit now accumulates Hyper/Reqwest/Streamed bodies
  chunk-by-chunk and aborts mid-stream instead of collecting the full
  body before comparing; Buffered keeps the post-hoc check.
- Proxy: decompression is budgeted at the decoder (Read::take on
  gzip/deflate/zstd, bounded brotli reader) via decompress_body_with_limit,
  so bombs are cut off at the byte budget instead of after full expansion,
  including stacked-encoding intermediates.
- Deeplink: show the usage section whenever any usage field is present,
  matching build_provider_meta persistence — a deeplink carrying only
  usageAccessToken/usageUserId no longer imports credentials invisibly.
- Codex catalog: after the lexical containment check, canonicalize the
  existing file and re-verify containment so symlinks inside ~/.codex
  cannot escape the config dir; the path_is_within doc comment no longer
  oversells the lexical check as symlink-safe.
- Grok sync: comment now matches the skip-all-symlinks behavior and each
  skip is logged, so sessions behind a symlink are diagnosable.
- Docs: CONTRIBUTING notes the packageManager pnpm pin and Corepack flow.

Regression tests follow the same methodology as round 1: reverting a
guard fails the corresponding test (server write-count assertions prove
the mid-stream abort; a truncated gzip stream distinguishes TooLarge
from read-to-end errors; symlink escape is rejected only after the
canonicalize re-check).

ff3bc242cc fix(Security): zip-slip on skill install, two credential leaks, and three panic paths (#5811)
* fix(security): harden GrokBuild credential handling and Codex/Anthropic transforms against malformed input

Three robustness/security fixes in the upstream v3.18.0 code, each with a
regression test.

1) grok_config: remove the unconditional XAI_API_KEY fallback in
   extract_credentials(). Credentials now come only from an explicit inline
   api_key or the process env var named by env_key. Silently substituting a
   different account's key (when the declared env_key var is unset) could
   leak that key to whatever base_url the config points at.

2) deeplink/provider: merge_grokbuild_config no longer resolves env vars
   into a plaintext api_key on import. A deeplink is untrusted input;
   resolving+inlining would persist the victim's environment secret into the
   imported provider's config.toml and ship it to the link's declared
   base_url. env_key now stays an indirection (name), not a resolved secret.

3) proxy transforms: stop panicking on malformed upstream data.
   - transform_codex_anthropic::anthropic_sse_to_message_value: only store a
     `message`/`content_block` when it is an object; otherwise treat it as
     empty, so the later `["content"]`/`["text"]`/`["signature"]` index
     assignments can't panic on a scalar/array Value.
   - streaming_codex_anthropic::responses_sse_events_from_anthropic_message:
     bail out with a failed-event when the buffered body is a top-level JSON
     array/scalar (a gateway that ignores stream:true), instead of
     index-assigning into a non-object.
   - mcp/grokbuild sync: normalize a non-table `mcp_servers` before
     inserting, avoiding a toml_edit IndexMut panic on a user-edited
     config.toml.

Panic findings verified with a minimal repro (serde_json index-assignment on
a non-object Value aborts). cargo test --lib: 2183 passed / 0 failed.

* fix(mcp): normalize a non-table `mcp_servers` in Codex config before insert

Same class of bug as the GrokBuild MCP fix in the previous commit, but in the
much more widely used Codex path.

`sync_single_server_to_codex` guarded only with `contains_key("mcp_servers")`,
so a user-edited `~/.codex/config.toml` where the key exists but is *not* a
table (`mcp_servers = "x"` / `[]` / `42`) skipped the rebuild and then hit
`doc["mcp_servers"][id] = …`, which panics in toml_edit's `IndexMut`
(`.expect("index not found")`). The panic happens inside a Tauri command and
unwinds across the FFI boundary; in the provider-switch flow it also fires
after the DB/live write already committed, leaving a half-applied switch.

Extract the normalize-then-insert step into `upsert_mcp_server_table()` so the
previously panic-prone logic is unit-testable without touching the real
`~/.codex/config.toml`, and normalize any non-table value to an empty table
before inserting.

Audited the sibling MCP writers while here: claude.rs / gemini.rs /
hermes.rs / opencode.rs do not have this pattern (their `contains_key` uses are
read-only checks), and the other index-assignments in codex.rs operate on
freshly built `Table::new()` values, which are safe.

Tests: 2 new regression tests (malformed non-table values normalize and insert;
an existing valid table keeps its entries). cargo test --lib 2185 passed / 0
failed; cargo clippy --lib -D warnings clean.

* fix(security): reject path-traversal entries when extracting a skill repo archive

`SkillService::download_and_extract` built the output path from the raw ZIP
entry name (`file.name()`), stripped only the leading `<repo>-<branch>/`
component, and then `dest.join(relative_path)` → `fs::File::create`. A crafted
entry such as `repo-main/../../../evil.sh` therefore escaped the destination
directory (zip-slip): arbitrary file write outside the temp extraction dir.

The archive is third-party controlled: it is downloaded from
`https://github.com/<owner>/<name>/archive/refs/heads/<branch>.zip`, and a
skill repo (`owner`/`name`) can be added through an untrusted `ccswitch://`
deeplink (`deeplink/skill.rs`), so the attacker fully controls the archive
contents.

Fix: resolve each entry through `zip::read::ZipFile::enclosed_name()`, which
rejects `..` components and absolute paths, before stripping the archive's
root directory and joining onto `dest`. Unsafe entries are skipped with a
warning. This matches what the two sibling extractors in this codebase already
did correctly (`extract_local_zip`, `webdav_sync/archive.rs`) — this call site
was the one that had been missed.

The extraction loop is split out into `extract_repo_archive()` so the guard is
testable without network access.

Verified the test actually catches the bug: with the guard reverted to the old
`file.name()` behaviour the new test fails ("zip-slip entry must not escape
dest (temp root)"); with the guard in place it passes.

cargo test --lib: 2186 passed / 0 failed; cargo clippy --lib -D warnings clean.

* fix(security): strip all credentials from the shared Gemini common-config snippet

`extract_gemini_common_config` skipped only two hardcoded keys
(`GOOGLE_GEMINI_BASE_URL`, `GEMINI_API_KEY`) and copied every other `env`
entry into the shared snippet. But `GOOGLE_API_KEY` is a first-class Gemini
credential — `provider.rs` resolves it via
`first_non_empty(env, &["GEMINI_API_KEY", "GOOGLE_API_KEY"])` — so it was
never stripped.

That snippet is not inert: `apply_common_config_to_settings` (live.rs)
deep-merges it into the `env` of *every other* Gemini provider that uses the
common config, and the snippet is auto-extracted on startup, on import, and on
switch. Net effect: account A's key gets written into provider B and sent to
B's `GOOGLE_GEMINI_BASE_URL`, which may be a third-party relay. Anything else
the user put in `env` (`GOOGLE_APPLICATION_CREDENTIALS`, a proxy
`*_AUTH_TOKEN`, …) leaked the same way.

Fix: also skip `Self::is_sensitive_config_key(key)`, reusing the pattern
matcher the Claude extractor already relies on for exactly this reason (its
comment notes a fixed enumeration "will always miss the next `*_API_KEY`").
`GOOGLE_API_KEY` matches its `_API_KEY` suffix rule. Shareable non-secret
config (e.g. `GEMINI_TIMEOUT_MS`) is preserved.

Verified the test catches the bug: run against the old two-key filter it fails
with "credential GOOGLE_API_KEY must not leak into the shared Gemini snippet";
with the fix it passes.

cargo test --lib: 2187 passed / 0 failed; cargo clippy --lib -D warnings clean.

* fix(security): validate skill directory from backups and sync-imported DB rows

The skill install pipeline sanitizes the install directory name, but two
entry points bypassed it entirely:

- restore_from_backup joined metadata.skill.directory (raw meta.json
  content) into the SSOT dir with no validation, allowing a crafted
  backup to copy attacker-controlled files outside the skills directory
  and to persist the poisoned value into the database.
- Sync import (WebDAV/S3) loads the remote database dump verbatim, so a
  malicious or compromised sync snapshot could plant a skills row whose
  directory contains path traversal. Every later raw join then operated
  on attacker-controlled paths — uninstall/remove_from_app would
  remove_dir_all outside the managed dirs (arbitrary directory deletion),
  and sync_to_app_dir would write/symlink outside them.

Add require_valid_directory() (built on the existing
sanitize_install_name) and enforce it at restore_from_backup,
sync_to_app_dir, remove_from_app, and uninstall. Regression tests cover
all three sinks plus the metadata path; each was verified against the
unguarded code first (disabling the guard makes the restore/uninstall
tests complete the traversal write/delete, failing the assertions).

Also fixes a pre-existing cargo fmt drift in mcp/grokbuild.rs.

* fix(security): reject path separators in sanitize_install_name on all platforms

The previous components()-based check was platform-dependent: on
Linux/macOS a backslash is not a path separator, so "a\b" parsed as a
single Normal component and was accepted as a valid install name — the
same value becomes a nested path when synced or restored onto Windows.
CI caught this on the Linux runner (the Windows runner passed).

Reject both '/' and '\' explicitly so the validation is
platform-independent; the components() check stays as the second layer
for dot segments, roots, and prefixes.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(security): close the remaining skill-install attack chain

The zip-slip guard added earlier only covered half the problem, and the
repo coordinates that decide *which* archive gets downloaded were never
validated at all. Together those two gaps let an attacker choose both the
bytes and where they land.

1) zip-slip, second layer. `enclosed_name()` only guarantees the entry does
   not escape the *archive's own* root, and it does not normalise the path —
   `..` survives verbatim in the returned value. Stripping `root_name`
   afterwards spends one level of that depth budget, so `repo-main/../evil`
   still escaped `dest`. On Windows it is worse: `root_name` comes from
   `split('/')` and may contain backslashes, which Windows treats as
   separators, so one `strip_prefix` can eat N components. Re-check the
   *actual* relative path for `ParentDir` right before `dest.join()`.
   Verified by reverting the guard: the single-`..` case escapes without it.
   (The existing test used two `..`, which `enclosed_name()` rejects on its
   own — it covered the half that was already guarded.)

2) Repo coordinates are now validated. `download_repo` formats owner/name/
   branch straight into
   `https://github.com/{owner}/{name}/archive/refs/heads/{branch}.zip`,
   and `deeplink/skill.rs` applied no validation whatsoever. URL parsing
   resolves dot segments, so a branch of
   `../../../releases/download/v1/evil` retargets the request at a *release
   asset* — arbitrary attacker-uploaded bytes. That is what made (1)
   reachable in practice: git itself will not let a tree contain `..`.
   Note the trigger is below "install": repos are enabled by default, so
   merely opening the Skills panel downloads and extracts.

   `validate_repo_ref` whitelists all three fields. Branch names legally
   contain `/` (`feature/x`), so the check is per segment rather than a
   blanket separator ban; an empty branch keeps its existing "use the
   default branch" sentinel meaning, same as `HEAD`. The main guard sits in
   `download_repo` — the single convergence point for all four call paths —
   because both `skill_repos` and `skills` can be overwritten wholesale by a
   sync snapshot, which no insert-time check can prevent. Entry-point checks
   (deeplink, `add_skill_repo`, agents lock) exist so bad values surface
   immediately instead of silently failing on every later panel open.
   `build_skill_doc_url` is covered too: it feeds `readme_url`, which the
   frontend hands to `openExternal`.

3) Regressions from the previous commits in this branch, both fixed:
   - `uninstall` ran the directory guard *before* `db.delete_skill`. That
     method has exactly one call site and is not exposed as a command, so a
     row with a dirty `directory` (pre-v3.11.0 installs, or anything
     `import_from_apps` still creates today — it has no sanitiser) became
     permanently undeletable from the UI. Now the guard skips the filesystem
     work but still deletes the row.
   - `sync_to_app` propagated with `?`, so one bad row aborted the entire
     app's skill sync — and that runs on provider switch. Now it warns and
     continues per entry.
   - `require_valid_directory` returned `sanitize_install_name`'s normalised
     value, which trims. A DB value of `" foo "` would then join as `"foo"`
     and miss the real directory. It now validates without rewriting.

4) Guard applied to the sinks the earlier commits missed: `migrate_storage`
   (rename + remove_dir_all), `update_skill` (delete + write attacker-named
   paths), `import_from_apps` (both a sink and the source of dirty values —
   `selection.directory` arrives raw over IPC), `resolve_uninstall_backup_source`
   (copies any directory into the backup area, which the UI then lists),
   `check_updates`, and `migrate_skills_to_ssot`.

5) Extraction limits. The archive bytes were fully attacker-controlled via
   (2), and this path had no ceiling of any kind, unlike
   `webdav_sync/archive.rs`. Added entry count, total extracted bytes, a
   symlink-target cap (zip 2.4.2's `make_reader` does not truncate at the
   declared `uncompressed_size`, so a symlink-flagged entry that inflates to
   gigabytes was read straight into memory), per-directory charging (a
   directory-only archive writes no content bytes but still consumes inodes),
   and a download-body cap (`response.bytes()` buffered the whole archive
   before any limit applied). Budget is charged on bytes actually read and
   written, never on sizes declared in the archive header.

   Symlink materialisation is charged to the same budget, and a target that
   contains the link itself (`dir/link -> ..`) is now rejected: the existing
   "must stay inside base" check passes for it, and the recursive copy then
   re-copies its own output every level until PATH_MAX.

6) Temp directories are now RAII. `download_repo` and `extract_local_zip`
   called `TempDir::keep()` immediately and relied on every exit path
   remembering `remove_dir_all`. Several did not — including
   `fetch_repo_skills`, the highest-frequency path of all. Returning the
   guard makes the leak unrepresentable at the call sites.

* fix(config): make removals and edits survive user-authored config shapes

The previous commits hardened the *write* side of the MCP tables against a
non-table `mcp_servers`. The read/delete side kept using `as_table_mut`,
which returns None for an inline table (`mcp_servers = { foo = {...} }` —
valid TOML). Removal then silently did nothing: the UI reported success, the
entry stayed in the file, and Codex loaded it again on next start. That is
worse than the panic it mirrors, because users usually reach for the toggle
precisely when an MCP server is misbehaving. Both Codex and GrokBuild now use
`as_table_like_mut` on both sides.

Normalisation is no longer silent either. Replacing a user's hand-written
`mcp_servers = "x"` with an empty table destroys data, so all four sites that
do it now log a warning first.

`update_codex_toml_field` had the same asymmetry with a different symptom:
when `model_providers` or `[model_providers.<id>]` was an inline table,
`as_table_mut` returned None and execution fell through to the "write a
top-level field" fallback. The user's `base_url` edit landed at the wrong
level, Codex never read it, and nothing reported a problem.

`opencode_config` parses `~/.config/opencode/opencode.json` with json5 into a
bare Value and never checked the root's shape. A user file of `[]` or a
scalar made `set_provider`, `set_mcp_server` and `add_plugin` all panic on
index-assignment, inside a Tauri command, unwinding across the FFI boundary.
(A top-level `null` is fine — serde_json promotes it.) Rejecting a non-object
root at the single read site fixes all three. Rejecting rather than rebuilding
is deliberate: the file also holds the user's own `model` / `theme` settings,
so a silent rebuild would delete them. Same treatment for the `provider` and
`mcp` sections, whose non-object forms made writes silently no-op.

* fix(proxy): recover a malformed Anthropic content_block as text

Sanitising a non-object `content_block` to `{}` stops the panic but creates a
quieter failure: the final Responses conversion matches on the block's `type`
and silently drops anything it does not recognise, so a garbled block header
turned into a `completed` response with empty output. The client saw the model
say nothing, with no signal that data had been discarded.

The replacement now carries `type: "text"`. The deltas that follow a malformed
header are usually well-formed, so this recovers the common case; a tool-use
block still yields nothing, exactly as before. A warning is logged when the
substitution happens.

The regression test now asserts through `anthropic_response_to_responses`
rather than on the intermediate value — asserting on the intermediate alone
passes while the client still receives an empty response.

* fix(grokbuild): decouple base_url from credential resolution, reject env_key-only links

`resolve_usage_credentials` called `extract_credentials(...).unwrap_or_default()`,
so a missing credential blanked the base_url too — even though it is written
right there in the config. Removing the `XAI_API_KEY` fallback in the earlier
commit widened that considerably: a GUI process on macOS does not inherit the
shell environment, so an `env_key` that resolves fine in a terminal resolves to
nothing here. The result was a Base URL shown in the UI that differed from the
one actually used, `{{baseUrl}}` expanding to empty in usage scripts (turning
requests relative), and native balance queries reporting "API key is empty"
while hiding the real cause. The two values are now resolved independently, via
the existing `grok_config::extract_base_url`, matching how the Codex arm of the
same function already works.

A deeplink whose only credential is `env_key` is now rejected by name. It was
already unimportable — `build_grokbuild_settings` has no `env_key` slot — but it
failed with the generic "API key is required", which reads like a malformed link
and invites the obvious "just carry the name over" fix. Carrying it over is
exactly what must not happen: the forwarder and the usage query both resolve
`env_key` at request time, so the victim's environment secret would still reach
the link's `base_url`. Same leak, merely deferred. The message says so, and the
test sets the probe variable so that restoring the resolution turns it red.

* fix(security): scrub credentials already leaked into the Gemini shared snippet

Fixing the extractor only prevents new contamination. A Gemini snippet is never
re-extracted once it exists — startup auto-extract and post-import extraction
both require `snippet.is_none()`, and the on-switch rewrite only covers Claude
and Codex — so existing users keep injecting the leaked key into live config,
the proxy upstream, and the new-provider form, where another account's key is
plainly visible.

Removing it from the snippet alone would make things worse. Merge and strip
cancel out by *value equality*: on switch-away, `remove_common_config_from_settings`
deletes the injected keys using the snippet as its only record of what to look
for. Once the key is gone from the snippet, the residue left in live config is
backfilled verbatim into the victim provider's `settings_config`, turning a
transient leak into a permanent one. So the cleanup covers all four locations at
once, and step order is itself a safety property: every fallible step runs before
the irreversible one, and a failure returns an error so the next start retries
from an intact state.

Deletion is by key *and* value, never by key name alone, so a provider's own
same-named key with a different value survives. The `~/.gemini/.env` edit
preserves layout rather than round-tripping through
`parse_env_file`/`serialize_env_file`: that pair drops comments, blank lines and
unparseable lines, collapses duplicate keys and re-sorts the file. Acceptable
when re-projecting everything, destructive for a targeted removal the user never
asked for — in testing it reduced a six-line fixture to one line, taking the
user's own key with it.

An audit record is written before any provider row changes, listing key names and
affected provider ids but *no values*: `settings` is not in `SYNC_SKIP_TABLES`,
so it is uploaded by WebDAV/S3 sync, and these are precisely the credentials that
must be destroyed. Keeping values would trade one deletion for a plaintext copy
that spreads across devices, has no UI to reach it, and never expires. It is
written only when absent, so a partially-applied earlier run cannot overwrite the
original pre-cleanup state.

Consequence, intentional: some Gemini providers will now report a missing API key
and need one entered. That key was never theirs. (The victim's own value was
already overwritten at merge time and cannot be recovered — worth noting in the
release notes, along with a recommendation to rotate the leaked key.) The snippet
row is deleted rather than set to `{}` when nothing shareable remains, and the
`cleared` flag is deliberately not set — either would disable auto-extract
permanently and prevent the user's legitimate shared config from ever coming back.

The frontend snippet validator is aligned with the backend matcher. It had the
same two hardcoded key names, so a hand-edited snippet could put `GOOGLE_API_KEY`
straight back with no error.

f6e37ed994 fix(ci): run backend checks on Windows/macOS and repair platform-gated tests (#5138)
* fix(ci): run backend checks on Windows/macOS and repair platform-gated tests

The backend CI job ran only on ubuntu-22.04, so every #[cfg(target_os =
"windows")] / macOS path — tests and clippy lints alike — was never
compiled or run. As a result main shipped 8 failing Windows unit tests and
a hard `cargo clippy -- -D warnings` failure on Windows, all invisible to
CI because it only builds and tests Linux.

Changes:

- ci: run the backend job on a {ubuntu-22.04, windows-latest, macos-latest}
  matrix (fail-fast: false); gate the apt install step on runner.os ==
  'Linux' and use `shell: bash` for the dist placeholder so it works on all
  three runners.

- misc.rs: fix 6 stale `anchored_upgrade_windows` tests. Commit 5092fe51
  removed codex from `prefers_official_update`, so codex now anchors to the
  package manager with no `codex update ||` prefix; update the five
  package-manager expectations accordingly, and retarget the no-sibling
  "official-update-without-fallback" test to `claude` (still in the list) so
  that branch stays covered instead of being silently dropped.

- codex_state_db.rs / codex_history_migration.rs: the two sqlite_home tests
  built TOML basic strings from Windows paths, whose backslashes are invalid
  escape sequences and made the override fail to parse; switch to TOML
  literal (single-quoted) strings so the path is taken verbatim.

- clippy (13 Windows-only warnings): move `use std::io::Write` into the
  #[cfg(unix)] block that actually uses it; convert 3 unneeded `return`s in
  Windows-gated tail positions to expressions; mark 9 POSIX-shell helpers
  #[cfg_attr(windows, allow(dead_code))] since they are used only by the
  macOS/Linux terminal launchers.

Verified locally (Windows 11, Rust 1.95.0):
  cargo test --lib                        → 1748 passed; 0 failed (was 1740/8)
  cargo clippy -- -D warnings             → clean (was 13 errors)
  cargo fmt --check                       → clean

* fix(skills): resolve home via get_home_dir so tests isolate on Windows

services/skill.rs called dirs::home_dir() directly in five places. On
Windows dirs::home_dir() resolves through the Known Folder API and
ignores HOME/USERPROFILE, so the CC_SWITCH_TEST_HOME override set by the
test harness never applied: the skill_sync integration tests scanned the
runner's real user profile, found no skills, and failed (the first panic
then poisoned the shared test mutex, cascading to all seven). On Unix
the harness also sets HOME, which dirs::home_dir() honors, so the suite
passed there by accident.

Route all five call sites through crate::config::get_home_dir(), the
crate-wide home resolver that prefers CC_SWITCH_TEST_HOME. The three
now-unreachable GET_HOME_DIR_FAILED error branches are dropped:
get_home_dir() is infallible, matching every other config-dir resolver.
Production behavior is unchanged (CC_SWITCH_TEST_HOME is unset outside
tests, so get_home_dir falls through to dirs::home_dir).

Add a regression test that discriminates on every platform by pointing
CC_SWITCH_TEST_HOME at a temp dir different from $HOME; it is marked
#[serial_test::serial] to stay mutually exclusive with the other tests
mutating the same process-global variable. Verified the test fails
against the old code on macOS with the same failure mode as Windows CI.
