Workflow Bugfix

Quick Summary

Goal: [Workflow] Trigger Bug Fix workflow — systematic debugging with root cause investigation, fix, and verification.

Summary: Execute the complete bug-fix sequence /investigate → /debug-investigate → /spec [mode=amend] → /plan → /plan-review → /plan-validate → /why-review → /spec [mode=tests] → /why-review → /artifact-review --type=spec-tests → RED /integration-test → /fix → /prove-fix → GREEN /integration-test → /integration-test-review → /integration-test-verify → /spec [mode=sync] → /workflow-review-changes → /changelog → /test → conditional /scan --target=domain-entities → /docs-update → /demo-guide → /workflow-end → /watzup, with spec-drift adjudication, end-to-start tracing, Goal Contract evidence, and explicit conditional skip reasons.

Workflow:

1. Detect — classify request scope and target artifacts.
2. Execute — apply required steps with evidence-backed actions.
3. Verify — confirm constraints, output quality, and completion evidence.

Key Rules:

• MUST ATTENTION keep claims evidence-based (file:line) with confidence >80% to act.
• MUST ATTENTION keep task tracking updated as each step starts/completes.
• MUST ATTENTION when creating/reviewing specs or tests, name Business Intent / Invariant Guarded or the protected business intent/invariant and ensure the test would fail if that intent breaks.
• MUST ATTENTION define success criteria before execution and loop until observable verification passes.
• MUST ATTENTION require regression tests to name Business Intent / Invariant Guarded and fail if that intent breaks.
• MUST ATTENTION apply the shared SDD Artifact Contract from shared/sdd-artifact-contract.md in the active skills root; use docs/project-config.json and docs/project-reference/docs-index-reference.md for project-specific conventions.
• MUST ATTENTION record current behavior, expected behavior, and unchanged behavior that must be preserved before fixing.
• MUST ATTENTION treat code-extracted specs and TCs as reference-only until canonical review accepts them.
• MUST ATTENTION allow any supported AI tool to implement or review when the shared contract, synced context, and local docs are available.
• NEVER skip mandatory workflow or skill gates.

Repeated Steps Disambiguation (CRITICAL for task creation)

[TASK-PLANNING] Before acting, analyze task scope and systematically break it into small todo tasks and sub-tasks using TaskCreate.

[IMPORTANT] Analyze how big the task is and break it into many small todo tasks systematically before starting — this is very important.

IMPORTANT MANDATORY Steps: /investigate -> /debug-investigate -> /spec [mode=amend] -> /plan -> /plan-review -> /plan-validate -> /why-review -> /spec [mode=tests] -> /why-review -> /artifact-review --type=spec-tests -> /integration-test -> /fix -> /prove-fix -> /integration-test -> /integration-test-review -> /integration-test-verify -> /spec [mode=sync] -> /workflow-review-changes -> /changelog -> /test -> /scan --target=domain-entities -> /docs-update -> /demo-guide -> /workflow-end -> /watzup

[EXPERIENCE ACCEPTANCE HANDOFF] /workflow-review-changes carries the conditional /experience-review gate after the fix and final rationale review. A changed observable result is exercised and inspected before expectation changes; a missing capability is ENVIRONMENT-BLOCKED, not a green regression result.

IMPORTANT MANDATORY Steps: /investigate -> /debug-investigate -> /spec [mode=amend] -> /plan -> /plan-review -> /plan-validate -> /why-review -> /spec [mode=tests] -> /why-review -> /artifact-review --type=spec-tests -> /integration-test -> /fix -> /prove-fix -> /integration-test -> /integration-test-review -> /integration-test-verify -> /spec [mode=sync] -> /workflow-review-changes -> /changelog -> /test -> /scan --target=domain-entities -> /docs-update -> /demo-guide -> /workflow-end -> /watzup

Single-pass steps are self-loop-backed (convergence lives in the skill, not the sequence): the /artifact-review --type=spec-tests step appears once in the flat sequence with no repeat wired — intentionally. It carries the full SYNC:double-round-trip-review self-loop (review → validate findings → fix validated findings → full re-review until the current exit bar is clear; round-2+ LOW-only findings are deferred), so a single occurrence still converges without spinning on polish; the workflow relies on that per-skill loop rather than re-listing the step. Code-change convergence is delegated to /workflow-review-changes (whose specialist scoped-re-run note lives in that skill).

Severity-floor clarification: the shared loop fixes only findings that block the current round. Round 1 fixes all validated findings; from round 2 onward, CRITICAL/HIGH/MEDIUM findings remain blocking, while LOW-only findings are recorded as deferred and never open another fix/re-review round.

[BLOCKING] Each non-skipped step MUST ATTENTION invoke its Skill tool — marking a task completed without skill invocation is a workflow violation, except a cited conditional skip explicitly authorized by canonical preActions.injectContext. NEVER batch-complete validation gates.

[CRITICAL] Plan Before Fix Gate: The /plan → /plan-review → /plan-validate steps are MANDATORY before /fix. You MUST ATTENTION create todo tasks for these plan steps AND complete them before proceeding to fix. Never skip planning — fixes without validated plans lead to incomplete root cause analysis and regressions.

Activate the workflow-bugfix workflow. Run /start-workflow workflow-bugfix with the user's prompt as context.

Spec check (before investigation): If docs/specs/ has a spec for the affected service/module, read the relevant ERD + business-rules + API-contracts files FIRST. Engineering specs provide domain context that reduces investigation time significantly. Command: ls docs/specs/ to discover available app buckets or flat system folders; then probe ls docs/specs/{app-bucket}/ or ls docs/specs/{system-name}/ to find the specific service spec.

[BLOCKING] Code Bug vs Spec Bug Gate (the bugfix-specialized instance of SYNC:spec-drift-adjudication / shared/sdd-artifact-contract.md → Drift Gates — same model, bugfix vocabulary): Before writing regression TCs, classify the issue:

• Code Bug (= CODE-WRONG) — the canonical spec describes intended behavior, but code diverged. Write regression TCs for the intended behavior before fixing code.
• Spec Bug (= SPEC-STALE) — the spec documents wrong behavior and code faithfully implements it. Update canonical spec/docs first via /spec [mode=amend], then write TCs for the corrected behavior.
• Ambiguous — ask the user or product owner which behavior is intended before writing TCs.

Include a behavior preservation note: current behavior -> expected behavior -> unchanged behavior to preserve -> regression TC/test evidence. Never normalize the divergence to whichever side currently passes — reconcile to canonical intent.

[BLOCKING] End-to-start trace before fix plan: Before /plan, /spec [mode=tests], or /fix, the investigation must include observed final state, final reader/query/renderer/assertion, backward hops through storage/projection/writer/consumer/producer, all feeder paths, hypothesis matrix, owning fix layer, and forward convergence proof. Missing trace evidence blocks the fix path.

Goal Contract propagation (workflow-owned): At workflow start, resolve the active Goal Contract per SYNC:goal-contract-satisfaction-loop (active plan goal.md → plans/goals/{YYMMDD-HHmm}-{slug}/goal.md → create from the bug report). Map root cause, regression-test evidence (RED fail + GREEN pass), and /prove-fix proof to the saved success criteria — each criterion gets file:line/command/report evidence in the Iteration Log. Pass the same goal file reference to every child step. Before /workflow-end, emit the final Goal Satisfaction matrix (PASS/FAIL/BLOCKED); workflow completion requires every required criterion PASS or BLOCKED with a user-facing escalation.

Steps: /investigate → /debug-investigate → /spec [mode=amend] → /plan → /plan-review → /plan-validate → /why-review → /spec [mode=tests] → /why-review → /artifact-review --type=spec-tests → /integration-test → /fix → /prove-fix → /integration-test → /integration-test-review → /integration-test-verify → /spec [mode=sync] → /workflow-review-changes → /changelog → /test → /scan --target=domain-entities → /docs-update → /demo-guide → /workflow-end → /watzup

[CONDITIONAL TERMINAL DOMAIN-ENTITY REFERENCE REFRESH] After /test and before /docs-update, run /scan --target=domain-entities to refresh the project-reference entity catalog only when the final diff changes an entity/model, DTO/data contract, persistence schema/migration, or entity-sync evidence represented in docs/project-reference/domain-entities-reference.md. Otherwise mark the scan step completed with a cited skip reason naming the changed files and why they are outside this scope; this is the explicitly authorized exception to the per-step skill-invocation rule.

[PERFORMANCE-SDD ROUTE] If this bug fix is performance-related (latency, throughput, memory, query speed, load behavior), run /performance-review and require SLA/benchmark evidence: target metric, baseline, measurement command, and acceptable regression budget. Do not use performance scope to bypass functional no-regression checks: run /test and any relevant functional checks when behavior can change. Update docs/specs for changed SLA, performance constraints, or behavior boundaries.

[TDD-FIRST BUG FIX] The two /integration-test occurrences are intentional and serve distinct purposes:

First /integration-test (RED phase): Write a regression test that REPRODUCES the bug. Run it — it MUST FAIL. If it passes, the test does not catch the bug. Proceed to fix only after the test fails — never start the fix while the test still passes. Second /integration-test (GREEN phase): Re-run integration tests after the fix — expect all to PASS. Confirms the fix works AND the regression guard is in place. /integration-test-review: Verify tests have real assertion value (not smoke/existence-only checks).

UI-intent maintenance (conditional) — runs alongside the /spec [mode=sync] step, only when the change carries user-facing behavior (else state the skip reason — backend-only change, no §6 change). When the fix changes user-facing behavior, run /spec (ui-intent intent) to refresh the affected Feature Spec §6 interaction surface — View Inventory, Key UI States, and the per-story (US-/OP-/BR-) click-path the bug touched — and link the governing /design-spec/mockup in the spec frontmatter so §6 and the design artifact stay coupled to what was actually fixed. The rules live in the shared block below (SYNC:ui-intent-layer) — follow it; do not restate it here.

End-to-Start Debugger Trace — For non-trivial bugs, failed verification, regression fixes, behavior-changing code, or unclear code flow, start from the observed final state and walk backward before proposing a fix.

1. Frame 0: observed end state — Name the exact user-visible output, failing assertion, log line, persisted value, API response, rendered UI, or aggregate bucket. Record the reader/query/renderer that produced it with file:line evidence.
2. Walk backward one hop at a time — Trace final reader -> projection/cache/storage -> writer -> consumer/handler/job -> producer/caller -> original trigger. At every hop record: input, transformation, output, owner, and evidence.
3. Enumerate all feeder paths — Find every upstream producer/caller/event/job that can write into the final path, including retry, async, cache, background, and alternate UI/API paths. Mark each path verified, ruled out, or still unknown.
4. Build the hypothesis matrix — For each plausible cause, list evidence for, evidence against, how to reproduce/verify, blast radius, and status (primary, contributing, ruled out, latent). Do not fix until competing causes are explicitly resolved or bounded.
5. Choose the owning fix layer — Identify the invariant owner and the lowest shared point that protects all downstream consumers. A fix at the symptom site is rejected unless the symptom site owns the invariant.
6. Prove convergence forward — After choosing the fix, walk start -> end again and show how the corrected state reaches the observed final output. Map each root cause to a fix part and each fix part to a test/proof.

BLOCKED until: final state named · backward trace written · all feeder paths enumerated · hypothesis matrix completed · owning fix layer justified · forward convergence proof mapped to tests.

NEVER: Start at the first suspicious code path. Collapse multiple producers into one "flow". Treat duplicate symptoms as duplicate records without proving the read model. Skip ruled-out hypotheses.

Nested Task Expansion Contract — For workflow-step invocation, the [Workflow] ... row is only a parent container; the child skill still creates visible phase tasks.

1. Call TaskList first. If a matching active parent workflow row exists, set nested=true and record parentTaskId; otherwise run standalone.
2. Create one task per declared phase before phase work. When nested, prefix subjects [N.M] /skill-name — phase.
3. When nested, link the parent with TaskUpdate(parentTaskId, addBlockedBy: [childIds]).
4. Orchestrators must pre-expand a child skill's phase list and link the workflow row before invoking that child skill or sub-agent.
5. Mark exactly one child in_progress before work and completed immediately after evidence is written.
6. Complete the parent only after all child tasks are completed or explicitly cancelled with reason.

Blocked until: TaskList done, child phases created, parent linked when nested, first child marked in_progress.

Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.

Test-Failure Fault Adjudication — When a test fails (or you are debugging or fixing a failure), the job is to determine who is at fault — the source code or the test code. Getting that verdict right matters more than turning the suite green. Binds every debug / fix / test skill identically.

1. Provisional verdict before touching either side. Classify the observed evidence as SOURCE-WRONG, TEST-WRONG, TEST-NOT-OPTIMAL, ENVIRONMENT-BLOCKED, or AMBIGUOUS; then /debug-investigate and trace end-to-start before editing. A green-again suite is NOT the goal.
2. Triangulate against the spec AND the source. If a governing Feature Spec covers the behavior (e.g. docs/specs/** — §3 ACs / §4 BRs / §5 invariants / §8 TCs), it is the tiebreaker for intended behavior — compare BOTH the production source and the failing test against it. With no spec, the documented intent / acceptance criteria / caller contract is the reference. Decide from this evidence whether the SOURCE is wrong or the TEST is wrong.
3. Classify who is at fault, then fix the wrong side at its root:
   • SOURCE-WRONG — production code violates the spec's intended behavior or a clear invariant → fix the source at the owning layer; keep or strengthen the test that caught it.
   • TEST-WRONG — the test encodes a stale or incorrect assertion, setup, or expectation that contradicts intended behavior → fix the test at its root. NEVER weaken an assertion, add a skip, or relax a timeout to force green.
   • TEST-NOT-OPTIMAL — intended behavior is valid but the test seam, timing, or assertion signal is fragile → improve the test without weakening the invariant.
   • ENVIRONMENT-BLOCKED — infrastructure or external state prevents a source/test verdict → preserve diagnostics and stop mutation until the environment is healthy.
   • AMBIGUOUS — evidence or intended behavior does not safely select an owner → ask the user or canonical owner before editing.
   • NEVER change a test to match broken source, and NEVER change source to satisfy a broken test. (Migration code excluded — schema/data migrations are one-time execution paths, not core application logic.)
4. Ask the user when intended behavior is unclear. If no spec covers the behavior, the spec is silent, or the spec is ambiguous about which side is correct, STOP and AskUserQuestion (or consult the canonical spec owner) before editing either side — never silently pick source or test just to make the suite pass.

Reconcile to intended behavior, never to whichever side currently passes — green can encode the very bug.

Read-only/report-only role boundary: when this block is carried by a report-only role (code-reviewer, quality-gate-review, spec-compliance-reviewer, tester, and any other agent whose definition declares it never edits source), "fix the wrong side" means RETURN the adjudicated verdict and the proposed repair to the parent — do not modify source, tests, generated carriers, or user data. The adjudication is the deliverable; the edit is the caller's. Without this sentence the block's step-3 imperatives read as write authority and directly contradict those agents' own declarations (e.g. tester.md "NEVER implement fixes"), which is the sibling SYNC:double-round-trip-review boundary applied to the same class of carrier.

AI Mistake Prevention — Failure modes to avoid on every task:

Re-read files after context changes. Context compaction, resume, or long-running work can make memory stale; verify current files before acting. Verify generated content against source evidence. AI hallucinates APIs, names, claims, and document facts. Check the relevant source before documenting or referencing. Check downstream references before deleting or renaming. Removing an artifact can stale docs, generated mirrors, configs, and callers; map references first. Trace the full impact chain after edits. Changing a definition can miss derived outputs and consumers. Follow the affected chain before declaring done. Verify ALL affected outputs, not just the first. One green check is not all green checks; validate every output surface the change can affect. Assume existing values are intentional — ask WHY before changing OR flagging one as a defect. Before changing or reporting a constant, limit, flag, cutoff, wording, or pattern, read nearby context and history, the CALLER's ordering, and 2+ sibling call sites of the same convention. A doc stating WHAT without WHY is missing rationale, not proof of a missing guard. Surface ambiguity before acting — don't pick silently. Multiple valid interpretations require an explicit question or stated assumption with risk. Assert the outcome your system owns, not the intermediate state your infrastructure owns. When verifying async work, assert the final business state — never the delivery/retry bookkeeping held in shared infrastructure that any co-running process can write. Such a check passes when run alone and flakes the moment anything else shares that infrastructure. Keep shared guidance role-relevant. Universal guidance must help every receiving skill or agent; code-specific obligations belong only in code-specific protocols.

Incremental Result Persistence — MANDATORY for all sub-agents or heavy inline steps processing >3 files.

1. Before starting: Create report file plans/reports/{skill}-{date}-{slug}.md and record Run ID, Task ID, Attempt ID, target scope, and target fingerprint.
2. After each file/section reviewed: Append findings, evidence, changed paths, and gaps immediately — never hold them in memory.
3. Delegated return: A sub-agent emits only the structured SYNC:subagent-return-contract envelope with exact totals, salient Critical/High findings (maximum ten), current attempt, and Full report: path. Inline user-facing output: Preserve the skill's requested explanation or teaching, with links to the persisted evidence; the delegated transport limit does not replace that deliverable. Do not paste a full review report into an envelope.
4. Parent synthesis: The main agent reads the full report for synthesis, acceptance, deduplication, and repair planning — not only when a named blocker exists. It preserves all severities beyond the transport cap.
5. Read-only boundary: A read-only leaf may write its report/repair proposal but MUST NOT edit source, generated output, or user data; the parent/owner performs repairs after acceptance.
6. Advancement gate: The parent records ACCEPTED for the current Attempt ID only after reconciling target, totals, gaps, and changed paths; stale or late attempts cannot advance dependent work.

Why: Context cutoff mid-execution loses ALL in-memory findings. Each disk write survives compaction. Partial results are better than no results, while explicit identity prevents a late result from being mistaken for the current run.

Report naming: plans/reports/{skill-name}-{YYMMDD}-{HHmm}-{slug}.md

Sub-Agent Return Contract — When this skill spawns a sub-agent, the sub-agent MUST return ONLY the structured envelope below. Main agent reads the envelope first, then opens the referenced report for synthesis, acceptance, deduplication, or repair planning; a full report is never pasted inline.

## Sub-Agent Result: [skill-name]

Status: ✅ PASS | ⚠️ PARTIAL | ❌ FAIL
Confidence: [0-100]%
Run ID: [stable run identifier]
Task ID: [parent task or phase identifier]
Attempt ID: [monotonic attempt/revision identifier]
Target: [exact files/paths or scope] @ [target fingerprint/commit]
Changed paths: [none | exact paths]
Finding totals: Critical=[n] | High=[n] | Medium=[n] | Low=[n]
Acceptance: PENDING | ACCEPTED | REJECTED — parent records the decision

### Findings (Critical/High surfaced — max 10 bullets)

- [severity] [file:line] [finding]

### Gaps / Unverified

- [missing host, runtime, coverage, or evidence limitation]

### Actions Taken

- [file changed] [what changed]

### Blockers (if any)

- [blocker description, or `none`]

Full report: plans/reports/[skill-name]-[date]-[slug].md

The ten-bullet limit is a transport limit, not a visibility limit: the full report may contain more than ten Medium/Low findings when no named blocker exists, and the parent MUST read it when synthesizing or deduplicating. The parent MUST reject a stale, duplicate, or superseded Attempt ID and MUST accept the current attempt before advancing a dependent step. Read-only leaves write repair proposals/reports only; they do not edit source, generated carriers, or user files.

Context budget — the return payload is a SUMMARY, not a transcript: no raw file contents / full diffs / verbatim logs inline, no re-pasted source. Everything beyond the envelope lives in the incrementally-written report. A sub-agent that would exceed the summary shape MUST persist the detail and return only the pointer; bounded transport must never become bounded visibility.

[BLOCKING] Capture a tech-agnostic UI/UX intent layer in every UI-bearing spec — a reader must be able to visualize how the feature works without naming any technology. When the feature has a user interface, the spec MUST ATTENTION carry an interaction-surface section so the application — not just its API — can be rebuilt on any stack:

1. View Inventory — list each view/screen by its UX ROLE and purpose (e.g. "list of items", "item editor", "confirmation step") and what information it presents. Describe by role, never by an implementation name.
2. Navigation Map — how a user moves between views: entry points, transitions, and exits. Trace how this surface connects to neighboring features already in the system.
3. Key observable UI States — the distinct states a user can observe per view (empty, loading, populated, error, success, permission-denied, etc.) — described as what the user perceives, not how it is rendered.
4. Per-story interaction flow — for each user story, the step-by-step click/action path from intent to outcome, cross-referenced to the logical IDs the spec already owns (US-/OP-/BR-).
5. Couple to the companion design artifact — keep deep visual fidelity (layout, tokens, pixel detail) OUT of the spec; it lives in the linked design-spec/mockup. Record that companion's path in the spec frontmatter so the spec stays the navigable hub.

M1-clean (NON-NEGOTIABLE): the prose names ZERO frameworks, routes/URLs, CSS, or component-class names — only roles, information, states, and flows. Technology detail belongs in the companion design artifact, never here.

Skip ONLY when the feature is backend-only (no UI) — state that reason explicitly in the section.

Severity Rubric — Classify every finding by consequence, not by effort, reviewer preference, or how annoying the fix is. One scale applies to every review, skill, agent, workflow, and host so a tier has the same meaning everywhere. Choose the highest credible consequence supported by evidence; do not lower a tier to make a round pass.

Finding vs observation (required): An observation becomes a finding only when it names the affected user/system/data/contract, the shipped consequence, the evidence location, and the normalized tier. INFO, advice, preference, duplicate wording, or an unsubstantiated concern is not a finding and must not reopen a loop. If the concern might affect a required behavior or gate but evidence is incomplete, emit NOT VERIFIABLE with the missing evidence and keep it unresolved; never silently convert uncertainty into LOW.

Severity	Action	Definition and examples
CRITICAL	Block immediately; escalate	Immediate material risk if shipped: authentication/authorization or safety bypass; secrets/PII exposure; irreversible destructive action; data loss/corruption; or a silent failure on a critical path. A failed binary gate that makes the result untrustworthy is represented as a separate synthetic blocker by the executable policy (not as an ordinary severity judgment).
HIGH	Must fix before PASS/merge	Material correctness or contract risk: wrong behavior on a supported path; violated business/data invariant; meaningful privacy or authority gap; breaking API/schema/compatibility change; likely harm to users/downstream systems; or a missing proof for a behavior-changing fix.
MEDIUM	Must clear the current round; escalate if the fix needs an owner decision	Bounded but consequential risk: an edge case, resilience/observability/testability/maintainability gap, credible future defect, or local architectural drift whose impact is real but not immediate material loss. An explicit follow-up records the escalation/residual risk; it does not make an open MEDIUM a clean pass.
LOW	Record and defer; never open another fix/re-review round from round 2 onward	Non-blocking polish with no credible present correctness, security, privacy, authority, availability, or data-integrity impact: wording/formatting, minor documentation or convention drift, optional defensive cleanup, or a cosmetic/refinement suggestion.

Consequence decision tree (apply in order): (1) Is a binary gate failed? Keep it as a separate hard blocker (the executable helper represents it as synthetic CRITICAL); do not use the ordinary severity label to hide what failed. Otherwise, would shipping permit immediate material security/safety/authority harm, irreversible destruction, data loss/corruption, or a critical-path silent failure? → CRITICAL. (2) Otherwise, does a supported path, invariant, public contract, privacy/authority boundary, compatibility promise, or behavior-changing proof fail with material user/downstream impact? → HIGH. (3) Otherwise, is there a bounded but consequential edge, resilience, observability, testability, maintainability, or architectural gap with a credible impact? → MEDIUM. (4) Otherwise, is the evidence sufficient to show only non-blocking polish with no credible present material impact? → LOW. (5) If the evidence needed to choose between steps 1–4 is missing, → NOT VERIFIABLE, not LOW. When multiple tiers fit, select the highest credible consequence; effort, implementation cost, reviewer discomfort, frequency alone, and proximity to the round cap never decide the tier.

Boundary examples (normalize before applying the round predicate): an auth bypass, exposed secret/PII, destructive command without an authority gate, or failed required test/generation/parity gate is CRITICAL; a wrong supported response, broken invariant/API/schema, meaningful privacy/authority defect, or unproven behavior-changing fix is HIGH; a bounded retry/timeout/alert/testability gap or credible maintainability drift is MEDIUM; a typo, formatting inconsistency, optional cleanup, or cosmetic suggestion proven not to affect present behavior is LOW. A missing fact about any of those boundaries is NOT VERIFIABLE until evidence or an explicitly documented residual-risk decision exists.

Classification procedure (required for every finding): (1) state the affected user, system, data, contract, or gate; (2) assess consequence if the issue ships; (3) assess exposure/likelihood and reversibility/detectability; (4) select the highest tier justified by those facts; (5) cite file:line or equivalent evidence and a confidence percentage. Effort, implementation cost, reviewer discomfort, and proximity to the round cap are never severity inputs. NOT VERIFIABLE is a pending evidence state, not one of the four tiers and never a LOW escape hatch: if the unresolved claim could affect required behavior, security, privacy, authority, availability, data integrity, or a binary gate, it remains an open evidence blocker until resolved or explicitly owner-accepted with documented residual risk. Classify an item LOW only when evidence supports the absence of credible present material impact.

Hard-gate rule: Binary gates (tests, required artifacts, security must-fix checks, generated parity, policy compliance) are not ordinary severity-rated findings. The executable helper records a failed gate as a synthetic CRITICAL blocker solely so one predicate can carry it; the report must still name the gate and failure evidence. A failed gate blocks at every round, including when all ordinary findings are LOW; never disguise a failed gate as LOW.

Score-based skills map their numeric scale onto these tiers — do not invent a parallel vocabulary:

• 0-2 criterion scoring (e.g. production-readiness-review): 0 = CRITICAL/HIGH (criterion unmet, blocks readiness), 1 = MEDIUM (partial, consequential gap), 2 = pass (no finding). If the criterion is only polish, use LOW rather than forcing a 0.
• Two-axis scoring (e.g. performance-review, impact × likelihood): high impact + high exposure → CRITICAL/HIGH; material impact with bounded exposure → HIGH/MEDIUM; low impact and low exposure → LOW. Record the axes and why the selected tier is the highest credible consequence.
• Scorecards / /20 grades (e.g. architecture-scalability-review): the aggregate score and verdict band are separate from finding severity. A sub-80 area is evidence to investigate, not an automatic CRITICAL/HIGH/MEDIUM/LOW label; classify each underlying gap by the consequence decision tree and keep advisory score deductions separate from blocking findings.

Domain-vocabulary normalization (mandatory): Specialized skills may keep a local reporting vocabulary, but it MUST feed this same four-tier round predicate — never a second severity system:

• BLOCKED, HARD FAIL, or FAIL is a blocking local verdict, not an automatic CRITICAL label. Classify the underlying consequence as CRITICAL when it is an immediate material risk or failed binary gate; otherwise classify it as HIGH or MEDIUM with evidence, while preserving the local block until the owning gate is satisfied.
• WARN is not permission to ignore a finding. Map it to MEDIUM when the gap is consequential, to LOW only when evidence supports no credible present material impact, or upward to HIGH/CRITICAL when the consequence warrants it. PASS/compliant is not a finding.
• UI P0/P1/P2/P3/P4 map to CRITICAL/HIGH/MEDIUM/LOW/LOW respectively as a starting point; override upward only when the evidence shows a higher shipped consequence. A P0/P1 accessibility or task-completion floor remains a blocking gate even when a local UI report calls it a priority rather than a severity.
• Numeric SRE/readiness or impact/likelihood scores are evidence inputs, not replacement tiers. Emit the score, the consequence, and the normalized CRITICAL/HIGH/MEDIUM/LOW tier together. INFO/advisory observations are not findings unless the evidence shows a material consequence.

A finding's tier drives the gate: CRITICAL/HIGH/MEDIUM remain actionable and blocking under the round policy; LOW may be tracked as a follow-up and, from round 2, does not by itself justify another fix/re-review. An owner decision may explain or schedule an open MEDIUM but does not turn it into a clean pass; owner acceptance never makes a failed binary gate pass and must record scope, rationale, and residual risk.

IMPORTANT MUST ATTENTION debugger trace gate: for non-trivial bug/fix/investigation/review work, start at the observed final output and trace backward through reader -> storage/projection -> writer -> consumer/job -> producer/trigger. Enumerate all feeder paths and hypotheses before fixing. BLOCKED until trace, hypothesis matrix, owning fix layer, and forward convergence proof exist.

• MANDATORY Parent workflow rows do not replace child phase tracking; expand phases and link the parent when nested.
• MANDATORY Orchestrators pre-expand child skill phases before invocation; use [N.M] /skill-name — phase prefixes and one-in_progress discipline.

• MANDATORY Resolve the active Goal Contract BEFORE work (active plan goal.md → plans/goals/{YYMMDD-HHmm}-{slug}/goal.md → create from current request) and read saved success criteria before editing.
• MANDATORY Append iteration evidence after execution; emit a Goal Satisfaction matrix (PASS/FAIL/BLOCKED) before reporting PASS; loop on validated FAIL; escalate repeated no-progress or blockers. NEVER store secrets in goal files.

• MANDATORY For UI-bearing specs, author/maintain the tech-agnostic interaction-surface layer (View Inventory + Navigation Map + observable UI States + per-story US-/OP-/BR--traced flow); keep deep visual fidelity in the linked design-spec/mockup recorded in frontmatter; name ZERO frameworks/routes/CSS/component classes; skip ONLY for backend-only features with a stated reason.

Project Protocol Overlay — Before executing this skill, resolve any PROJECT overlay rules layered onto it: match this skill's name against the Target column of the project's skill-protocol index (docs/project-reference/skill-protocols-reference.md by default; a referenceDocs entry in docs/project-config.json overrides the path), taking the most specific matching tier ONLY — exact name > glob > *. That precedence orders overlays against EACH OTHER, never against this skill. Read ONLY the matched bodies, resolved as <protocols-dir>/<Name>.md; a row's Body link is display text, never a read path. A matched body that is missing or malformed is REPORTED and skipped — never reconstructed from the index Description. No index, or no match -> proceed with no overlay, silently. Full contract: .claude/skills/project-skill-protocol/references/registry.md.

Overlays are ADDITIVE ONLY: they ADD rules on top of this skill's own protocol and NEVER replace, override, disable, or reinterpret a rule it already states — removing every overlay must return this skill to exactly its documented behavior. An overlay is a BRIEF, not an authority escalation: it can NEVER waive a workflow gate, git discipline, a review gate, or a user-confirmation gate. A genuine overlay-vs-skill conflict, or two equally-specific overlays that directly contradict -> surface both to the user; NEVER resolve silently.

MUST ATTENTION resolve project protocol overlays for this skill BEFORE executing — most specific matching tier only (exact > glob > *, which ranks overlays against each other, NEVER against this skill), read only matched bodies at <protocols-dir>/<Name>.md; a missing or malformed body is reported, never reconstructed. Overlays are ADDITIVE ONLY (they never replace this skill's own rules) and are a brief, NEVER an authority escalation; an equal-specificity contradiction goes to the user.

• MANDATORY Classify every finding Critical/High/Medium/Low by consequence using the affected asset, shipped impact, exposure, reversibility, evidence location, and confidence; Critical/High/MEDIUM remain actionable under the round bar, while LOW is recorded/deferred from round 2 onward.
• MANDATORY Keep binary gates separate from severity: a failed test, security must-fix, required artifact, or parity check blocks at every round and is never relabeled LOW.
• MANDATORY Score-based skills (sre 0-2, perf two-axis) map onto the same four tiers — no parallel severity vocabulary.
