feat(operator-mind): post-spawn verify + pre-flight + retry guard - #5
Conversation
… servers
Phase 1 of operator-mind: KCode used to report `✓ PID X (3.0s)` for
every background spawn even when the spawned server crashed at boot
on EMFILE / ENOENT package.json / EADDRINUSE / missing dep. The
model received a positive signal and would re-spawn the same broken
command on the next turn, accumulating dozens of orphaned processes
(50+ npm run dev / bun --watch leaked over a single session).
The verifier sits at the close of the bash-tool background path and:
1. Pattern-matches the command against known long-running server
spawns (next dev, vite, npm/bun/pnpm/yarn run dev, python -m
http.server, flask run, uvicorn, gunicorn, rails s, php -S,
caddy run, live-server, nodemon, serve/http-server).
2. Resolves the actual port from PORT= env, --port=N, --port N,
-p N (only for known servers), php -S host:N, python -m
http.server N, or the framework default.
3. HTTP-probes 127.0.0.1:PORT/ with retries (~3.5s budget).
4. Treats 2xx/3xx/4xx as alive (404 = server up, just no route),
5xx and connection failures as dead.
5. On dead, returns is_error=true with a multi-line diagnostic:
pid liveness, declared port, cwd, last 15 lines of stderr, and
a "Do NOT retry without diagnosing first" guard with the most
likely root causes spelled out.
The verifier is a separate module (`src/core/bash-spawn-verifier.ts`)
so it can be reused by future operator-mind primitives (e.g. the
upcoming pre-flight duplicate-spawn guard in phase 2).
Verified end-to-end against the failure path (`PORT=N npm run dev`
in an empty dir → ENOENT package.json → real failure surfaced) and
the success path (`python3 -m http.server N` → ✓ live at HTTP 200).
Tests: 53 unit cases covering detection, port extraction, probe
edge cases (200/404/500/000), PID liveness, and full integration
against a real Bun.serve() on an ephemeral port.

MethodologyThis audit was produced by the KCode audit engine: a deterministic pattern library scanned the project for known-dangerous code patterns, then every candidate was verified against the actual execution path. Findings listed here are only those where the execution path was confirmed. Pattern library version: 1.0 — patterns derived from real bugs found in production C/C++ codebases (network I/O, USB/HID decoders, resource lifecycle, integer arithmetic).

Refuses background server spawns when the system is already in a
state that would make the spawn fail. Catches the two failure modes
from the Artemis bricking session:
* Port collision: `PORT=15423 npm run dev` while something else is
already listening on 15423 → spawn would race and EADDRINUSE.
Uses `ss -tlnp` to find the occupant PID and process name; refusal
report includes 3 concrete options (reuse, kill, pick another port).
* inotify saturation: when /proc/sys/fs/inotify/max_user_instances
is ≥85% used, watch-mode frameworks (next/vite/astro/nodemon/
live-server/webpack/node-dev) boot straight into EMFILE and crash.
Refusal report tells the operator how to clean leaked watchers
AND how to raise the limit via sysctl.
Both checks only fire when the command matches a known server-spawn
pattern (reusing detectServerSpawn from phase 1), so plain Bash calls
like `ls`/`git status`/`npm install` are unaffected. The inotify
snapshot is cached for 30s to keep the cost negligible (one find
+ one /proc read per Bash call, max).
Wired into bash.ts immediately after isBackground is determined,
before the spawn happens. Returns is_error=true so the model has
to actually reason about the failure instead of looping.
53 → 61 tests for the verifier+preflight pair, plus end-to-end
verification with a real Bun.serve() port collision.

… spawns
Closes the operator-mind triad. Phases 1 and 2 made failures visible
and refused doomed spawns; phase 3 catches the case where the model
sees a failure, ignores it, and re-issues the exact same command
on the next turn — the failure mode that bricked the Artemis session.
Behavior
--------
After every Bash invocation the executor records (cwd, normalized
command, was-error, error-tail) in a process-local sliding window
(64 entries, 8-attempt retry window). On the next Bash call:
- If the new command matches a known server-spawn pattern AND the
same (cwd, normalized command) was attempted within the retry
window AND that attempt was an error → the executor returns a
STOP report and SKIPS execution.
- The STOP report names the command, the cwd, how many Bash calls
ago the failure was, the first 8 lines of the previous error,
and three concrete options the model must take before retrying:
diagnose / change command / read more state.
- After the warning fires once, an internal acknowledgment bumps
the entry forward so the very next attempt runs normally — this
is an escape hatch in case the model legitimately knows
something the heuristic doesn't.
Scope is narrowed to commands that match detectServerSpawn() — the
same set used by phases 1 and 2. Sudo prompts, file ops, builds,
tests, and any other one-shot command flow through unaffected. The
sliding window still records them for ordering accounting but never
fires a warning on them. This avoids a real conflict with the bash
sudo-cache tests, which legitimately call executeBash multiple
times with the same sudo command.
Implementation
--------------
- New module `src/core/bash-spawn-history.ts` (180 lines):
recordBashAttempt, detectImmediateRetry, acknowledgeRetryWarning,
clearBashHistory (test helper), snapshotBashHistory (test helper),
internal normalizeCommand (collapses whitespace, treats PORT=N
and --port N changes as the same intent so the model can't bypass
by bumping the port).
- `src/tools/bash.ts`: split executeBash into a thin public wrapper
(does the phase-3 check + records the attempt at the end) and a
private `_executeBashInner` (the original 760-line body, untouched).
- 14 unit tests covering: scope filtering (one-shot commands ignored),
same/different cwd, same/different command, whitespace normalization,
PORT/--port intent equivalence, retry-window expiry, history bounding,
acknowledge-then-retry, and the structure of the STOP report itself.
End-to-end verification
-----------------------
Spawned `PORT=N npm run dev` in an empty tmpdir. Three sequential
calls: 1st rejected by phase 2 (inotify saturated, real failure),
2nd intercepted by phase 3 (STOP, retry detected), 3rd ran through
phase 2 again after acknowledgment. All three phases compose cleanly.

MethodologyThis audit was produced by the KCode audit engine: a deterministic pattern library scanned the project for known-dangerous code patterns, then every candidate was verified against the actual execution path. Findings listed here are only those where the execution path was confirmed. Pattern library version: 1.0 — patterns derived from real bugs found in production C/C++ codebases (network I/O, USB/HID decoders, resource lifecycle, integer arithmetic).

changed the title
Self-review of the previous /fix overhaul surfaced six issues. Three were high-severity correctness bugs that could silently corrupt user code; three were medium-severity correctness/robustness bugs. All six are closed here with targeted tests. HIGH #1 — fixDartJsonNullCheck over-matched The regex `/\\bas\\s+(int|double|num|bool|String)\\b(?!\\?)/g` had no context requirement, so it rewrote any primitive cast on any line: final count = users.length as int; // ← was getting rewritten final x = someCall() as String; // ← was getting rewritten Business-logic casts that had nothing to do with JSON were silently turned into `as int? ?? 0` / `as String? ?? ''`, changing runtime behavior (exception → default value). The fix tightens the regex to require a `json['key']` subscript immediately preceding the `as`: /(\\bjson\\s*\\[\\s*['"][^'"]+['"]\\s*\\]\\s*as\\s+(int|...))\\b(?!\\?)/g Only casts that live inside the exact `json[...] as T` shape are rewritten now. A regression test (mixed.dart) exercises a file with both kinds of casts and asserts the non-json ones are untouched. HIGH #2 — whole-file sweep amplified false positives The dart-007 fixer sweeps the entire file (needed because the audit engine dedupes repeated matches of the same pattern+file into a single Finding, so only the first line is reported). Combined with HIGH #1, a single false-positive finding could rewrite every cast in the file. Narrowing the regex in #1 largely addresses this — the sweep now only touches lines that contain the literal `json['...']` subscript, so the blast radius is bounded to fromJson factories. HIGH #3 — writeFileSync was not atomic if (modified) { writeFileSync(file, lines.join("\\n")); } A crash mid-write (Ctrl-C, OOM, disk full, process kill) left the user's source file half-corrupted with no recovery. Introduced `atomicWriteFileSync()`: write to `<target>.kcode-fix-<rand>.tmp` then `renameSync` over the target. The rename is atomic on POSIX since the temp file is in the same directory. On rename failure the temp file is cleaned up and the error propagates. MEDIUM #4 — setState guard detection short-window fixDartSetStateAfterDispose only looked at the 3 non-blank lines immediately before `setState(` for a mounted/disposed guard. A valid guard placed just after the `await` but separated from the setState by comments or blank lines was missed, causing a duplicate guard to be inserted. Replaced the short lookback with a full-span walk from the await line (finding.line) to the setState call. Regression test state.dart exercises a 6-line gap and asserts exactly one guard. MEDIUM #5 — dart-005 assumed `mounted` always exists The fixer inserted `if (!mounted) return;` without verifying the enclosing class is a State<T> subclass. In rare cases (helper classes, mixins, non-Flutter Dart with a local `setState` method) `mounted` is undefined and the inserted guard fails to compile. Added `isInsideFlutterState()` which walks backward looking for a `class X extends ... State<...>` declaration; if not found within 400 lines, the fix is skipped with an explanatory message. Regression test helper.dart has a non-State class named `NotAState` and asserts no guard is inserted. MEDIUM #6 — scanner could escape the project root and loop on cyclic symlinks findSourceFiles used readdirSync + statSync, which follows symlinks silently. A link pointing outside the audited project leaked files from unrelated directories into the scan; a cyclic link (a→b→a or link→.) would walk forever until file-descriptor exhaustion. Scanner now: - Resolves the project root to a realpath once at start. - Resolves every directory AND file via realpath before visiting. - Rejects resolved paths that don't equal or start with `<projectRealpath>/` — closes the root-escape hole. - Tracks visited directories and files in two Sets keyed by real path — closes the cycle-loop hole. Two regression tests in audit-engine.test.ts create sibling directories with escaping and cyclic symlinks and assert the scanner neither leaks outside files nor loops. Both tests degrade gracefully on platforms where symlink creation requires privileges. Bump to v2.10.11. Audit-engine suite now has 33 passing tests (was 28) covering all six holes.

feat(operator-mind): post-spawn verify + pre-flight + retry guard
Extend sanitizer warning to include which messages were stripped: "Stripped 2 empty messages: #3:assistant(array(0)) #5:user(string)" Helps trace the systematic source of empty messages we're seeing on every turn. The filter is working (400s gone) but the underlying bug that produces empty messages per-turn is still unknown. Co-Authored-By: Kulvex Code <contact@astrolexis.space>
External review priorities #1 (fixtures) and #5 (metrics) addressed in this sprint, since they're parallelizable and both touch the same quality-feedback loop. Pattern metrics infrastructure: types.ts gets a new PatternMetrics shape: { hits, confirmed, false_positive, needs_context, confirmed_rate?, false_positive_rate? } AuditResult.pattern_metrics: Record<pattern_id, PatternMetrics> populated at scan time, omits patterns that never matched (vs. emitting hits=0) so consumers can distinguish "didn't fire" from "fired but everything passed". audit-engine.ts iterates verified results, increments per-pattern counts, sums multiples (raw-candidate counts pre-dedupe) so the hit count reflects total regex matches not deduped-per-file pairs. Computes confirmed_rate and false_positive_rate when hits > 0. report-generator.ts adds a "## Pattern hit-rate" section showing the top 10 by hit count with confirmed_rate as a percentage. Helps the auditor identify low-signal patterns (high hits, low confirmed) that should be tightened or downgraded in maturity. Fixture coverage: 39 → 51 (out of 311). Added high-value fixtures for the v314 vertical packs that previously had zero coverage: crypto-001-rand-for-key-material (positive + negative .py) crypto-003-md5-sha1-for-auth crypto-007-tls-verify-off crypto-009-ecb-mode inj-001-sql-string-concat inj-002-subprocess-shell-true inj-005-path-traversal des-001-pickle-loads des-002-yaml-full-load fsw-001-port-handler-no-check (positive + negative .cpp) fsw-005-buffer-getdata-unchecked fsw-010-cmd-arg-before-validate Each fixture has both a positive (must match the regex) and a negative (must NOT match) case. The negatives demonstrate the canonical mitigation: secrets module instead of random, parameterized queries, allowlisted path containment, FW_ASSERT-guarded buffer use, length-checked cmd args. README.md updated from "28 patterns out of 257" to "51 out of 311". The previous number had drifted across multiple library expansions. Tests: 6 new (pattern-metrics.test.ts) + 12 new fixture pairs exercised by the existing harness. Full audit + UI suite 571/571 green (24 new + 547 prior). Per the roadmap, Milestone 1+2 deliverables are now complete: ✓ JSON consistente ✓ /review útil ✓ /fix honesto ✓ /pr estructurado ✓ métricas ✓ fixtures (initial pass on the v314 verticals) Next: Milestone 3 — pattern expansion (Phase A high-priority web verticals: SSRF, JWT verify bypass, Zip Slip, etc.) and deepening the flight-software differential pack.

…ial pack External roadmap priority #5: profundizar flight-software porque es donde KCode tiene moat real. Five new patterns in the fsw pack, focused on parser / dispatcher / log-injection bug shapes that commercial SAST tools have no domain knowledge of. flight-software pack: 15 → 20 patterns. Library: 323 → 328. Fixture coverage: 63 → 68. New patterns: fsw-016-frame-length-as-offset `header.get_lengthField()` (just deserialized from the wire) used as `moveDeserToOffset` argument without an upper bound. A malformed frame with `length=0xFFFFFFFF` walks the deserializer past the buffer. Same shape as the FprimeDeframer.cpp bug we flagged in earlier scans. fsw-017-component-array-id-no-check Component arrays (m_channels, m_packets, m_ports, m_filteredIDs, m_handlers, m_callbacks) indexed by an externally-supplied ID without a bound check. Telemetry / dispatcher OOB on malformed packets. Verifier checklist accepts intra-process port-input (sibling component) as a trusted boundary. fsw-018-cmdhandler-stub-only-response Ground-command handler whose entire body is a single `cmdResponse_out(opCode, cmdSeq, OK)`. Almost always a stub the developer forgot to fill in — operators trust a silent-noop command on the production deployment. fsw-019-logger-format-from-arg `Fw::Logger::log(fmt, ...)` where fmt is a function parameter, not a literal. Format-string injection: %n writes memory, %x leaks stack. Also covers `CFE_EVS_SendEvent` for cFS/cFE deployments. fsw-020-fwtime-getseconds-no-tb-check `t1.getSeconds() - t2.getSeconds()` arithmetic without first checking matching TimeBase. Subtle bug — works in unit tests where both Times share TB_PROC_TIME, breaks in flight when the spacecraft transitions between TB_NONE / TB_PROC_TIME / mission UTC mid-mission. Bugs found and fixed during fixture validation: fsw-018 regex required `\w+::` (out-of-class definition); my fixture used in-class definition without the `Class::` prefix. Tightened regex to `(?:\w+::)?` so both forms match. fsw-020 had a forward-only negative-lookahead `(?![...].getTimeBase)` that misclassified the negative fixture (which has the check BEFORE the subtraction). Dropped the lookahead and let the verifier's mitigation checklist handle the upstream-check case. Updated negative fixture to use Fw::Time::sub() — the framework helper that doesn't trigger the regex shape and is the idiomatic fix. All 5 new patterns have recipes in fixer.ts (annotation tier, since flight-software guards need human judgment, not mechanical rewrites). Tests: full suite 709/709 green (10 new fixture assertions + 699 prior). Patterns now: 328. Fixtures: 68/328 (~20.7%, was 19.5% at v333). Phase B complete. Next: Phase A round 3 (Rust unwrap-in-hot-path, C# BinaryFormatter variants, Swift insecure storage), or jumping to Phase 2 of the roadmap (CVE feed integration / diff-based audit / AST-based matching).

Summary
Three composable primitives that close the operator-mind triad: KCode no longer reports
✓ PID X (3.0s)for spawns that crashed at boot, no longer launches doomed spawns into a saturated system, and no longer accepts blind retry of an identical command after a fresh failure. Together these would have prevented yesterday's Artemis bricking session from ever happening — the model would have hit a wall at iteration 1 instead of accumulating 50+ leaked dev-server processes.All three phases share a single command-detection layer (
detectServerSpawn) so they never fire on plain Bash calls (ls,git status,npm install, etc.).Phase 1 — post-spawn HTTP verification
After a background spawn that matches a server pattern, probe
127.0.0.1:PORT/with a ~3.5s retry budget instead of trusting the wrapper's "PID: X" output. 2xx/3xx/4xx counts as alive (404 = server up, just no route). 5xx and connection failures count as dead.Failure path (Artemis case,
PORT=15423 npm run devin empty dir):is_error: true. Model has to reason instead of looping.Phase 2 — pre-flight: port + inotify
Refuses background server spawns BEFORE they run when:
ss -tlnpshows the declared port already bound. Refusal report includes occupant PID + process name + 3 options (reuse / kill / different port)./proc/sys/fs/inotify/max_user_instances≥85% used and the framework is watch-mode (next/vite/astro/nodemon/live-server/webpack/node-dev). Refusal explains how to clean leaked watchers AND how to raise the limit via sysctl. Snapshot is cached for 30s.Phase 3 — retry interception
Tracks the last 64 Bash invocations in a process-local sliding window keyed by
(cwd, normalized command). Normalization collapses whitespace and treatsPORT=N/--port Nchanges as the same intent so the model can't bypass by bumping the port.When the model issues a server-spawn command that matches a recent failure (within the 8-attempt retry window), the executor returns a STOP report and skips execution:
After the warning fires once, an internal acknowledgment lets the very next attempt run normally — escape hatch for the case where the model legitimately knows something the heuristic doesn't.
Phase 3 is scoped to commands that match
detectServerSpawn()so sudo prompts, file ops, builds, and tests are never affected. The bash-sudo-cache tests still callexecuteBashwith the same sudo command repeatedly — they continue to work because phase 3 ignores them.End-to-end composition
Verified the three phases compose cleanly with

It is: a defensive layer that makes the Bash tool report failure honestly and refuse to participate in spawn loops. It catches the 80% case (broken dev-server spawns) cheaply and surgically.
It isn't: a general "make the model smarter" feature. The model still has to reason about the failures it sees. What this PR changes is that the model now actually SEES the failures instead of being told everything succeeded.
