Assesses the production viability of findings, filtering out debug-only features and assertion traps. Use when findings have been validated and you need to confirm they are triggerable in production release builds (with assertions disabled). Don't use for writing reproduction scripts or patches.

Critic (/mantis critic) System Goal Production Viability Expert. Filters validated security findings to confirm if they remain triggerable in standard release and production configurations. Command Definition Command: /mantis critic [ target root=<path ] [ snapshot root=<path ] [ snapshot id=<id ] [ state root=<path ] Description: Assesses the production viability of findings, filtering out debug only features and assertion traps. Parameters: target root : AUTHORITATIVE path to the target codebase root. Overrides all other locator sources and is sentinel exempt (Block A path 1a). Defaults to unset. snapshot root : Path to the pinned, immutable snapshot copy for this pass (a.k.a. SNAPSHOT ROOT ). Used as CODE ROOT when target root is unset (Block A path 1b). snapshot id : The SNAPSHOT ID the orchestrator computed for this pass. Used for the Block A sentinel check and for the per finding Block B drift comparison in Step 3. If omitted, fall back to active snapshot.snapshot id from state. state root : Path to the root of the Mantis state directory containing workspace/ (defaults to . ). Every workspace/... path in this file is resolved relative to state root ; with the default . this is identical to today's workspace/ . Input/Output Contract Reads : workspace/findings/ (loads all findings regardless of status; also reads each finding's optional discovery commit for the per finding snapshot match check). workspace/kb/THREAT MODEL.md (if exists, to check deployment intent and the KB's recorded kb snapshot id ). workspace/.mantis state.json (to track current loop pass and to read active snapshot.{root,snapshot id,snapshot pinned} for locator resolution and provenance). Target source code files under the resolved CODE ROOT (the pinned snapshot root when snapshot pinned ), at paths/lines in code paths with contextual offset. Writes : Updates findings in place (sets "production viability" , "critic reasoning" , and appends history). Appends to workspace/learnings.jsonl . Preconditions : Findings must exist in workspace/findings/ . Idempotency Guarantee : Overwrites viability fields in place. It must check if a critic entry for the current pass is already recorded in the history array, and check workspace/learnings.jsonl to ensure it does not write duplicate records if run again on the same input. Instructions Evaluate validated findings to determine if they represent actionable security flaws in a compiled, optimized release build. Adopt a highly skeptical, adversarial stance. Do not trust the reasoning of previous stages. Re verify the code path independently to definitively prove or disprove production viability. Locator Resolution (do this first) Critic is a CODE READING stage (it inspects the target source), so it is NOT a findings only stage: run all of Block A. Resolve CODE ROOT and the sentinel per Block A before loading findings. [!NOTE] CURRENT PASS CHECK (defensive; the binding guarantee is on the harness per mantis pipeline adapter Scenario 2): if active snapshot is present AND active snapshot.pass != state.pass number , treat the snapshot as STALE for this pass — STOP "stale active snapshot: pass mismatch" or degrade as HALT ( snapshot pinned effectively false: no authoritative verdicts, Block B NOT MATCHED, reproduce not attempted ). This catches a custom harness that preserved active snapshot across the Stage 15 pass increment without re pinning. The reference meta agent re pins every pass, so this check never fires there. Block B itself cannot detect this (it is snapshot id only, not pass aware). SNAPSHOT ID for this stage: let SNAPSHOT ID be the value of snapshot id if provided, else active snapshot.snapshot id from workspace/.mantis state.json . If neither is present (no snapshot id AND no active snapshot in state), OR Block A resolved CODE ROOT via path 1d (no args, current dir), then SNAPSHOT ID is UNAVAILABLE (MODE OFF = today's default): treat every Block B check in Step 3 as NOT MATCHED and treat the KB freshness gate in Step 2 as FAILED. Do NOT stop; degrade as described below. When active snapshot IS present but snapshot pinned is false (HALT mode), SNAPSHOT ID is the recorded live: id and IS available — Block B still returns NOT MATCHED (snapshot pinned is false), but the Step 3c "MODE OFF exception" below does NOT fire: a NOT MATCHED result is treated as drift → CONDITIONAL VIABLE, never NON VIABLE (which calibrate drops). Execute the critic evaluation as follows: 1. Load Findings: Read the JSON files in the workspace/findings/ directory. You must load all findings regardless of status (including "VALID" , "FALSE POSITIVE" , "PROVISIONALLY VALID" , and "NEEDS RESEARCH" ) so they can be processed or logged to long term memory. If none exist, notify the user. 2. Evaluate Global Repository Intent (KB freshness gated): Read workspace/kb/THREAT MODEL.md (if it exists). Check the Deployment Intent section. KB freshness gate — REQUIRED before any blanket mass mark (3 state rule): Determine the snapshot the KB was built against. Read it from ONE of these sources (try in order, first match wins): 1. The literal KB SNAPSHOT: token on the FIRST line of workspace/kb/THREAT MODEL.md (threat model writes this as a bare header; architecture writes comment wrapped <! KB SNAPSHOT: ... on each KB file). For architecture files, scan for the KB SNAPSHOT: substring inside the comment. Do NOT look for kb snapshot id: or Snapshot: — those tokens are never written and the gate would never match. 2. Else the kb snapshot id value in workspace/.mantis state.json (which architecture writes in its state stamp step). 3. Else "" (no prior KB provenance). The blanket mass mark below is gated as follows: MODE OFF (no active snapshot in state — no sync ): SKIP the freshness gate entirely. The blanket SAMPLE OR TEST mass mark is permitted as today (byte for byte today's behavior) — the KB was built against the live tree and there is no snapshot to compare against. HALT or PINNED ( active snapshot IS present): the blanket mass mark is permitted ONLY if the recorded KB SNAPSHOT: (or kb snapshot id ) is present AND is byte for byte equal to the current SNAPSHOT ID resolved in Locator Resolution above (no fuzzy compare). If it is missing, empty, or does not equal SNAPSHOT ID , you MUST NOT mass mark: skip this blanket action entirely and evaluate every finding individually in Steps 3 5. Only when the freshness gate passes (or is skipped in MODE OFF): if the threat model explicitly states the entire repository is exclusively a tutorial, sample project, or test suite (e.g., Intent: SAMPLE OR TEST ONLY ), you MUST mark all findings as SAMPLE OR TEST regardless of where they are located in the file structure, and skip the remaining per finding viability checks. 3. Acquire Targeted Code Snippets (snapshot matched): For each finding where status is "VALID" or "PROVISIONALLY VALID" (skip this and the following evaluation steps for "FALSE POSITIVE" or "NEEDS RESEARCH" findings): a. Resolve the target file from the finding's code paths per Block A step 3: code paths are SNAPSHOT RELATIVE, so read them under CODE ROOT. Strip a trailing :<digits to get the line number; :// means a URL, not a file; any entry that is not <path :<int is a non source LOCATOR — do an existence check only, with no line logic. b. Snapshot Match Check (Block B): compute MATCHED / NOT MATCHED for this finding by comparing its discovery commit against the current SNAPSHOT ID . c. Drift / missing file / out of range guard (fail safe — NEVER NON VIABLE): If Block B yields NOT MATCHED , OR the resolved target file does not exist under CODE ROOT, OR the designated line number is beyond the end of the file (out of range), then you MUST NOT run the domain specific viability analysis (Steps 4 5) for this finding and you MUST NOT mark it NON VIABLE (a missing file is not dead code; NON VIABLE is the value that mantis calibrate DROPS). Exception (MODE OFF only — no active snapshot): if SNAPSHOT ID is UNAVAILABLE (MODE OFF: no active snapshot in state and no snapshot id ) AND the sole cause of NOT MATCHED is the missing/unavailable SNAPSHOT ID (not a missing file or out of range line), treat it as "cannot compare" and fall through to normal evaluation (Step 3d). This preserves today's behavior for non sync runs. In HALT mode ( active snapshot present, snapshot pinned=false ), this exception does NOT fire: Block B is NOT MATCHED and the finding is drift → CONDITIONAL VIABLE (the "Otherwise" branch below), never NON VIABLE (which calibrate drops). The missing file and out of range conditions still force CONDITIONAL VIABLE regardless of pinning or mode. Otherwise (drift, missing file, or out of range): set production viability = CONDITIONAL VIABLE and write a critic reasoning drift note naming the cause, e.g.: "Snapshot drift: discovery commit=<disc != active SNAPSHOT ID=<id (or the target file/line is no longer present at the pinned snapshot); could not re verify viability, defaulting to CONDITIONAL VIABLE (conservative)." Then record the update via Step 6 and continue to the next finding. (This finding is still logged to long term memory in Step 7 as CONDITIONAL VIABLE .) d. MATCHED, file present, line in range: read the target file from CODE ROOT and read at least 15 lines of preceding context and 15 lines of succeeding context around the designated line numbers. This targeted window is necessary to analyze surrounding structures and macro definitions. Additionally, inspect repro hints and history for empirical execution telemetry recorded by mantis reproduce (e.g. build profile , sanitizers used , assertions disabled , ingress blocked ). Use this empirical execution telemetry to corroborate release build viability. Proceed to Steps 4 5. 4. Evaluate Domain Specific Viability Constraints: For Memory Safety Flaws: Locate the allocation source of the affected buffer. Determine if it is allocated with safety margins or trailing padding. If the out of bounds access is contained within physical padding, mark it NON VIABLE . For Logic & Authorization Flaws: Verify that the flawed logic or bypassed endpoint is actually accessible in standard production deployments. If the flaw relies on a debug only backdoor, a mock authentication provider, or a test only route, mark it NON VIABLE . 5. Determine Viability Status: Assign one of the following viability statuses to the finding to ensure we prioritize correctly: NON VIABLE : The flaw is unreachable or compiled out in production. This includes: Disabled Assertions (Memory Flaws): Bugs that rely on standard assert() , debug abort() , or development only panics to trigger crash/DoS states, where NDEBUG strips them and the code returns safely. Debug Only Features: Conditionally compiled with debug flags (e.g. ifdef DEBUG ). Blocked by Environmental Controls: Blocked by standard, non configurable production environmental controls (e.g., OS level permissions, kernel level sandboxing, read only filesystems) that cannot be bypassed. SAMPLE OR TEST : The issue resides in example code, test suites, fuzzing harnesses, or validation frameworks. CONDITIONAL VIA
