Every finding was verified against source; claims that could not be verified are marked. + +--- + +## 1. Executive summary + +hawk-eco is in unusually good health for a codebase of this size: + +- **0** golangci-lint issues, **0** go vet issues, **0** reachable vulnerabilities (govulncheck), **1** trivial staticcheck finding +- Full test suite **passes**; engine packages average **~87% coverage**; sandbox/auth 74–78% +- The security architecture is genuinely strong where it matters most: fail-closed Docker-only execution, cap-drop/no-new-privileges/read-only containers, keychain credential storage, constant-time daemon auth, atomic session persistence + +However, the audit found **1 critical, 12 high, ~20 medium, and ~30 low** findings. The dominant themes: + +1. **Built-but-unwired safety infrastructure** — panic recovery exists but is never installed; the self-improvement memory loop never persists; budget tracking exists but is never fed. +2. **Dead subsystems shipping in production** — `engine/async` (0% coverage, 2 confirmed bugs), `engine/docs` (~2,000 lines, zero importers), `MessageBus` (700 lines), approval gate, composio stub. +3. **Fail-open trust edges** — project-controlled `.agents/runtime.jsonc` executes arbitrary shell as root at image build time; HTTP decision hooks fail open silently; bash subprocesses inherit API-key env vars. +4. **Performance regressions in hot paths** — O(N) re-embedding per codegraph query, full-transcript deep clone per turn, full-prefix TUI re-render per chunk, per-call regexp compilation. + +--- + +## 2.

Findings + +Severity scale: **CRITICAL** (crash/data loss/RCE), **HIGH** (security boundary or functional break), **MEDIUM** (correctness/reliability/race), **LOW** (hygiene/performance). + +### 3.1 CRITICAL + +**C1. No panic recovery anywhere in the production binary** +- `cmd/hawk/main.go` — `Execute()` has no `recover()`. `cmd/errors.go:33` (`panicRecovery`) and `internal/crash/crash.go` are **dead code** — zero production callers (verified by grep). +- `internal/crash/crash.go:17-18` states explicitly: *"Do NOT call this from cmd/hawk yet — wiring into the binary entry point is a future wave."* +- **Impact:** any panic in a background goroutine (TUI render, spinner at `cmd/chat_tools.go:234`, tool execution) kills the process mid-session with no session save, no crash report, no cleanup. +- **Fix:** wrap `Execute()` in `panicRecovery(saveFn)` and install `crash.Install()` at startup. *(fixed: `panicRecovery` wraps the TUI execute path; `crash.Install()` wired in `cmd/hawk/main.go`)* + +### 3.2 HIGH + +**H1. `.agents/runtime.jsonc` → arbitrary root code execution at image build time** — `internal/sandbox/runtime_deps.go:14-67`, `container.go:154,236-238` +`runtime_extra_deps[]` becomes raw `RUN ` layers in the sandbox image; `runtime_startup_env_vars` becomes `docker run -e KEY=VALUE`. The file is project-controlled and agent-writable. A malicious repo executes attacker shell as root during `docker build` (build network unrestricted, `--cap-drop` does not apply), and the result is baked into the session image — a persistent session backdoor. +**Fix:** allowlist validation (reject `curl|wget|nc|sh|bash|python` in deps; fixed key set for env; no `PATH`/`HOME`/`LD_PRELOAD`). *(fixed: blocklisted dep terms rejected with `slog.Warn`; env validated against a fixed key set)* + +**H2. Project secrets readable + exfiltratable by default** — `container.go:143` (project rw mount), `mode.go:160-170` (`ModeAllowsNetwork`: workspace → network on), `bash.go:604-673` +Default mode mounts the whole project (incl. `.env`, credentials) rw into a container with **outbound network**. A compromised agent can exfiltrate project secrets. Strict mode denies network but is not the default. `NetworkProxy`/`BlockPrivateNetworks` exist but are never wired into production (only tests reference them). +**Fix:** make strict mode's network policy the default for workspace, or wire the blocklist; document the tradeoff. + +**H3. HTTP decision hooks fail open silently** — `internal/hooks/http_hooks.go:45-88`, `decision.go:118-142` +Every failure path (marshal, request build, client error/3s timeout, non-2xx, decode, unknown action) returns `nil`, and `ExecuteDecisionHooks` treats nil as "no opinion, proceed". No logging on HTTP errors. A downed compliance/guardrail hook → every guarded tool call silently allowed. +**Fix:** return a deny decision + `slog.Warn` on error; make fail-open an explicit config option. *(fixed: deny + `slog.Warn` by default; `FailOpen` explicit opt-in)* + +**H4. SSE generation >5 min permanently wedges the daemon** — `internal/daemon/daemon.go:215` (`WriteTimeout: 300s`), `streamSSE` `:721-777` +`WriteTimeout` is an absolute deadline; `streamSSE` ignores `fmt.Fprintf` errors (`_, _ =`) and only exits on `r.Context().Done()` or channel close — neither fires when the write deadline lapses. The handler never returns; the session stripe lock (`:580-582`) and global `concurrencySem` (`:551-557`) are held forever; with the default cap of 4, all subsequent `/v1/chat` requests 503 permanently. Agentic tasks routinely exceed 5 min. +**Fix:** exit the SSE loop on write error; use `http.ResponseController` for a per-write deadline that resets per flush. *(fixed: `writeSSE` reports failures, handler exits the loop; per-write deadline via `ResponseController`)* + +**H5. External SIGINT/SIGTERM/SIGHUP bypass session save** — `cmd/chat_update.go` (no `tea.InterruptMsg`/`tea.QuitMsg` cases — verified absent), Bubble Tea v2 handles both and exits without `saveSession()`; SIGHUP unhandled (default kill). +`kill -TERM`, terminal close, or ssh drop mid-run → transcript lost, temp files left. +**Fix:** handle `tea.InterruptMsg`/`tea.QuitMsg` → run the same save path as the two-stage ctrl+c; install SIGHUP handler. *(fixed: `InterruptMsg`/`QuitMsg`/SIGHUP all route through the shared quit-save path)* + +**H6. Self-improvement memory never persists (default CLI path)** — `internal/intelligence/memory/evolving.go:36-40` (`NewEvolvingMemory` never calls `Load`), `internal/engine/lifecycle/lifecycle_adapters.go:14-39` (adapter only calls `Learn`/`Retrieve`/`Format`, never `Save`) +Everything learned at session end is lost at process exit; `OnSessionStart` always returns empty guidelines. The Reflexion-style loop is a **no-op** in the shipped CLI. +**Fix:** `Load()` in constructor, `Save()` after `Learn` (debounced), test the round-trip. *(fixed: `Load` in constructor, atomic `Save` after `Learn`, round-trip test)* + +**H7. Budget enforcement is split-brain** — `internal/engine/lifecycle/limits.go:14` (`MaxCostUSD` "default: from MaxBudgetUSD" — never implemented), `:86` (`IsExceeded` checks `MaxCostUSD` only), `RecordCost`/`RecordTokens` have **zero production callers** (verified by grep); production budget flows through `Session.SetMaxBudgetUSD` and enforcement at `stream.go:515`. `VibeLimits` sets `MaxCostUSD: 5.0` with `MaxBudgetUSD: 0` (limits.go:147-156) — inconsistent. +**Fix:** fallback `MaxCostUSD = MaxBudgetUSD` when unset; wire `RecordCost` into the stream cost accounting; make `VibeLimits` consistent. *(fixed: `MaxCostUSD` falls back to `MaxBudgetUSD`; accessors mutex-protected (M1); cost synced from the session cost accumulator)* + +**H8. Codegraph semantic search is O(N) full re-embedding per query** — `internal/codegraph/embeddings_cgo.go:13-57`, `tool/codegraph.go:482` +Every `SemanticSearch`/`HybridSearch` `SELECT`s all nodes then recomputes `GenerateEmbedding(n)` per node (hash-based, uncached), then cosine-compares. On 100k-node repos this is seconds per tool call. The precomputed `CodeVectorStore` (`vector_store.go:122-239`) exists but is unused by `SemanticSearch` (dead duplication; itself brute-force O(N²) sort, no locks). +**Fix:** `CodeGraph.embeddingFor` memoizes embeddings in a bounded cache (200k entries, content-hash key covering every field `extractFeatures` reads; full reset when full — far cheaper than recomputing per query). `SemanticSearch` now goes through the cache; repeated queries and unchanged nodes skip recomputation. 3 new tests (memoization, content invalidation, bound). *(fixed)* + +**H9. Mission retry loop is structurally broken; failures report success** — `internal/multiagent/mission.go:158,238-258`, `worker.go:206`, `graph.go:80-90`, `cmd/mission.go:134-136` +`feature.Branch` is deterministic (`hawk-mission//`); `git worktree add -b` fails on retry 2+ because attempt 1's branch survives worktree removal — every retry fails, branch leaks. `runFeatureSet`/`RunWaves` return `nil` unconditionally → `hawk mission` **exits 0 when all features fail** (CI sees green). +**Fix:** the retry loop now rewrites `feat.Branch` to `/attempt-N` before every worker call (unique per attempt); `createWorktree` falls back to checking out an existing-but-unchecked-out branch (leaked branch or validation reuse); `removeWorktreeDetached` deletes the branch after removing the worktree (best-effort); `cmd/mission.go` returns an error — non-zero exit — when any feature failed, so CI no longer sees green on failure. *(fixed)* + +**H10. `engine/async`: goroutine leak + double-loop + missing terminal event (dead code today)** — `internal/engine/async/engine.go:93-106`, `:49-56`, `event.go:146`, `engine.go:128-146` +`Stop()` cancels ctx but the loop is parked in `subQ.Next()` (`<-sq.notify`) → **leak on every stop**; `Start()` after `Stop()` spawns a second loop draining the same queue (double processing); on stream error `EventDone` is never emitted → consumers hang; `toAsyncEvent` has no default for `compact_start`/`blast_radius` events → zero-value garbage events; `ReplyTo` contract is unfulfilled; subscribers can't unsubscribe. +**Fix:** rewritten engine: `Stop()` cancels a loop ctx and joins via WaitGroup (bounded wait); `Start` after `Stop` spawns one fresh loop; single-threaded loop drains the queue via non-recursive `pop()` after each notify (no stack-growth, no parked-goroutine leak); `Cancel()` aborts the in-flight turn directly (a queued cancel could never be popped while the loop is blocked inside the turn's stream); `EventDone` is always emitted (success, stream error, or canceled turn) and forwarded to `ReplyTo`; unmapped events map to `EventInfo` preserving the raw type; `EventQueue.Unsubscribe` added; full-UUID event/submission IDs. **9 tests, 88.2% coverage (was 0%), race-clean.** *(fixed)* + +**H11. `engine/docs`: ~2,000 lines shipping with zero importers** — `internal/engine/docs/` (docgen.go, doc_updater.go, external_docs.go) +Verified: no file outside the package references it. Within it: multi-line doc comments truncated to last line (doc_updater.go:350-368), `OldDoc` populated from *new* content (`:56,:87`), false-positive machine for capitalized words (`:522-539`), parser chokes on nested parens (`:330`), `ExternalDocs.Cache` never written (`external_docs.go:77`), methods of generic types dropped (docgen.go:938-951). +**Fix:** either wire to a `hawk docs` command or delete; at minimum fix the top-3 bugs. *(fixed: deleted — dead since f0aa8fd, no importers, six known bugs; recoverable from git history if ever wanted)* + +**H12. Bash tool subprocesses inherit API-key env vars** — `internal/tool/task_tools.go:80`, `bash.go` (`exec.CommandContext` with no `cmd.Env` → full `os.Environ()`) +Guard regexes (bash.go:102-105) block obvious dump patterns but are trivially bypassed (`python3 -c "import os;print(os.environ['ANTHROPIC_API_KEY'])"`). Keys are readable by anything the agent runs. +**Fix:** strip provider key env vars (or pass a scrubbed env) when spawning agent commands. *(fixed: agent subprocesses spawn with scrubbed env — `internal/env/scrub.go` builds the allowlist once from `ScrubSet`)* + +### 3.3 MEDIUM + +| ID | Finding | Location | +|---|---|---| +| M1 | Data race on `LimitTracker.limits` accessors (read/write without mutex) while daemon/multiagent goroutines call `SetMaxTurns` concurrently | `internal/engine/lifecycle/limits.go:129-132` *(fixed: mutex-protected accessors, covered by `limits_test.go`)* | +| M2 | `ParseAndApplyMemoryOps` swallows all errors (nil bridge, discarded `bridge.Remember`, malformed JSON); 0% coverage; runs in background goroutine | `sleeptime_ops.go:25-35`, `stream.go:626` *(fixed: returns `error` — `ErrNoMemoryOps`, wrapped parse/remember errors via `errors.Join`, nil-bridge error; call site logs `slog.Warn`; 7 new tests)* | +| M3 | `SkillDistillerAdapter` returns nil on error — "not configured" and "failed" indistinguishable | `lifecycle_adapters.go:50-52,77-80` *(fixed: `Retrieve` logs `slog.Warn` with the `Search` error)* | +| M4 | Cost metrics use fabricated session IDs (`"session_"+UnixNano`) instead of the real session ID | `lifecycle.go:158-160` *(fixed: `OnSessionEnd` reads the real ID via `Session.SessionID()` — added in `execution_graph_observations.go`; nil-getter falls back to empty)* | +| M5 | `MissionApprovalGate` is dead code (zero production callers); workers auto-approve everything incl. arbitrary bash; `sessionApproved` map would race when wired | `multiagent/approval.go:110-144`, `worker.go:61-66` *(fixed: wired into production — `Config.ApprovalGate` consulted by the worker permission fn; `Check(ctx, toolName, summary)` classifies bash/network/web actions as risky; `sessionApproved` mutex-protected)* | +| M6 | Validation-worker cleanup regressed (cancellable ctx kills `git worktree remove` → permanent leak) | `multiagent/worker.go:144` *(fixed: detached-context cleanup + branch deletion)* | +| M7 | Oversized MCP response (>1MB scanner cap) silently kills the client connection; server child stays alive; no recovery | `internal/mcp/mcp.go:95,167-179` *(fixed: dead-server flag marks the connection on readLoop end, kills the child process, and `callWithTimeout` fails fast)* | +| M8 | `Composio.ExecuteTool` returns fake success (`Success: true` echoing params); agents would report unexecuted actions | `internal/composio/composio.go:147-177` *(fixed: package deleted — unwired stub, zero importers; provider implementations belong in `external/eyrie` per the architecture note; recoverable from git history)* | +| M9 | In-memory `Tracer` accumulates spans unboundedly (daemon lifetime); `Disable()` doesn't stop recording | `internal/observability/oteltrace/trace.go:45-59,112-116` *(fixed: `StartSpan` checks `enable`, buffer capped at 10k spans; dropped spans stay functional)* | +| M10 | `diffsandbox.absPath` is lexical-only; symlinked intermediate components escape the sandbox root | `internal/diffsandbox/sandbox.go:419-435` *(fixed: component-wise walk with `Lstat` — symlinks resolved and containment-re-checked against the resolved root, dangling symlinks rejected; covers macOS `/var → /private/var`)* | +| M11 | `PolicyManager` defaults to `DecisionAllow` — stated deny-by-default posture not reflected | `internal/sandbox/manager.go:48` *(fixed: default is `DecisionDeny`; project policy takes precedence with global filling gaps; reload no longer resets to allow)* | +| M12 | userns remap conditional; without it container runs as root with rw project mount; no `--user` fallback | `container.go:33-40,149-153` *(fixed: `--user :` appended when userns remap is unavailable)* | +| M13 | Host-side file tools: check-then-open symlink TOCTOU; name-based sensitivity (`secrets.txt` allowed) | `internal/tool/file_read.go`, `file_write.go`, `safety.go:251+` *(fixed: resolve-then-revalidate + `os.SameFile` fd guard; writes land at the resolved parent; `blockedBasenames` covers secrets/credential files; symlink-escape tests added)* | +| M14 | Per-call `regexp.MustCompile` in hot paths (5 sites) | `internal/feature/eval/filters.go:13-32`, `tool/spec_checklist.go:119-149`, `tool/ticket_compliance.go:62`, `feature/fingerprint/project_conventions.go:180-181` *(fixed: all hoisted to package-level vars)* | +| M15 | Full-transcript deep clone per access in `RawMessages()` — quadratic over session length | `internal/engine/persistence_service.go`, callers `context_governor.go:120-148` *(fixed: hot per-turn reads use the read-only, non-retaining `RawMessagesView()` (no clone); `RawMessages` keeps its deep-copy snapshot contract)* | +| M16 | TUI viewport re-renders full prefix per streamed chunk — O(messages) per token | `cmd/chat_viewport_render.go` *(no change needed: render cache + incremental stream tail already make per-chunk rendering amortized O(tail); incremental-vs-full-rebuild equivalence asserted by `chat_viewport_render_test.go`)* | +| M17 | `hawk path` 1.83s wall; `MigrateProviderSecrets`→`newEyrieEngine()`+`gateway.New()` runs on **every** root command | `cmd/root.go:136`, `internal/config/eyrie_engine.go:15-17,127-133` *(fixed: migration moved off the root preamble into the chat/print/repl branches and before `runChat()`; cold commands like `hawk path` never build the engine)* | +| M18 | Unbounded TUI-side growth (history, messageQueue, messages, `toolResultExpanded`) | `cmd/chat_submit.go:51`, `chat_model.go:185` *(fixed: prompt history capped (200) via `pushHistory`, queue capped (100) via `enqueueMessage`, messages already trimmed at 500, expansion map reindexed+pruned on trim; unit tests added)* | +| M19 | Async hook goroutines never drained (`WaitAsync` has no callers) — unbounded under tool loops | `internal/hooks/hooks.go:134-156` *(fixed: session-end drains queued async hooks via `WaitAsync` with a 30s cap after `ExecuteAsync`)* | +| M20 | Legacy `Sandbox.Run` fails open when `Enabled=false` (host `bash -c`); no production callers — latent footgun | `internal/sandbox/sandbox.go:134-135` *(fixed: fails closed unless explicitly opted out via `Tier == TierOff`)* | + +### 3.4 LOW (selected) + +- Engine stream retry ignores `Retry-After`, fixed 1–3s delay (`stream.go:448`) *(fixed: `streamRetryDelay` parses a "retry in|after N[ms]" hint from the stream error (matching eyrie's retryDelayRe), honors it capped at `maxStreamRetryDelay` (60s), else falls back to the existing linear 1–N backoff; `isRetryableStreamError` broadened to surface rate-limited (429) and 503 streams for retry; added `stream_retry_test.go`) +- Deployment retry can re-select the same dead deployment (`deployment_router.go:149-150`) *(fixed in `external/eyrie` (PR #105, merged to eyrie main at `ed62022`): `selectDeploymentChoice(choices, exclude)` skips the just-failed deployment when alternatives remain; Chat/StreamChat tracks a stage-scoped `recentlyFailed` id; single-deployment stages still retry once to trip the breaker; `TestDeploymentRouterRetriesPreferDifferentEndpoint` asserts dead is tried ≤1× and healthy is reached. Hawk pins eyrie to the published pseudo-version (`026bfdd`) per the submodule/module release-parity CI gate; the fix enters Hawk on the next eyrie release tag — the submodule pointer will bump then.)* +- Substring-based retry/credit/overflow classification causes spurious retries and silent emergency-compact (`stream_helpers.go:32-40`, `retry.go:41-57`, `chat_service.go:258-264`) *(partially addressed: `isContextOverflow` tightened to match structured provider signals — `context_length_exceeded`/`context_length_error`/`exceeds the limit` — and to require a token/context qualifier alongside the legacy "too long"/"too many tokens" phrasing so ordinary "request timeout, too long" no longer spurious-compacts (reduces false positives, cannot storm); remaining substring heuristics in `retry.go` `IsRetryable` left as-is per the risk note — they are additive (more retry coverage) but traffic-driven tuning is still recommended)* +- Linux token-file write non-atomic; concurrent Set races (`auth.go:235-264`) *(fixed: token store now uses `internal/safewrite` — atomic temp-write + fsync + symlink guard)* +- Non-atomic `0o600` writes without fsync (`session/cross_session.go:376`, `memory/knowledge.go:519`) *(fixed: both now use `safewrite.WriteFile`)* +- Unbounded `EndSession` goroutine without context (`stream.go:681`) *(fixed: `IntegrationPipeline.EndSession` now takes `context.Context` and bails on a canceled context; caller passes the session ctx)* +- Sandbox image pulled by mutable tag, no digest pinning (`image.go:40-42`) *(fixed: `HAWK_SANDBOX_IMAGE_DIGEST` env pins `repo@sha256:` when set)* +- `ModeOff` disables path guard (`path_guard.go:21`) *(no change — intentional: `--sandbox off` is an explicit opt-out of all sandbox protections incl. the path guard; changing it risks breaking host-mode workflows)* +- Session load bricks on >1MB message line (`session.go:389`); fixed tmp name `id.jsonl.tmp` across processes (`session.go:97`); stale `.wal` after recovery *(fixed: `scanJSONLLines` reader with a 16 MB per-line cap drains+logs oversize/corrupt lines instead of bricking the load; corrupt meta line is a load error (500) while an empty file is still ErrNotFound (404); `RecoverFromWAL` reuses the same tolerant reader; Save's temp name is namespaced with getpid())* +- MCP stale `pendErrors` entries + zombie on failed connect (`mcp.go:118-155`) *(no change needed: all `callWithTimeout` terminal paths (success/timeout/ctx-cancel) and the EOF/readLoop-exit path already delete `pendErrors[id]` and `pending[id]`; the connection-lost zombie is resolved by M7's dead-flag + child-kill)* +- `trackSession`/`sessions` grow unboundedly in long-lived daemon (`daemon.go:75,924`) *(fixed: in-memory sessions index capped at `maxTrackedSessions` (1000), evicting oldest by LastUsed)* +- `MessageBus` (700 lines) dead in production; `hooks.EventBus` unused *(partial: `internal/hooks/events.go` + its test deleted (genuinely dead — no production callers); `multiagent.MessageBus` retained — it backs the agent file-lock feature (`AcquireLock`/`IsLocked`) and its lock tests exercise real behavior, so the "dead in production" claim is inaccurate for it)* +- Plugin security scanner advisory-only; `CheckExtensionMalware` has no callers *(fixed: `internal/plugin/malware_check.go` deleted)* +- `WithTimeout` no-op cancel footgun (`timeout.go:33-40`); fabricated session IDs; dead exports (`RemainingTime`, `Countdown`) *(fixed: `RemainingTime`/`Countdown` now wired into both `runPrint` and REPL print paths (one remaining-time notice per turn); fabricated `session_` replaced with `genID()` in the memory manager startup; WithTimeout cancel is correctly deferred at both call sites)* +- Staticcheck: unused `getKeys` (`coverage_extra_test.go:131`) *(no change needed: verified clean — `getKeys` is no longer present/used)* + +### 3.5 Verified-clean (defense-in-depth that holds) + +- Docker-socket not mounted;
