-## Workflow
+## Debugging Workflow
 
-- Diagnose (bounded to error context): stack trace -> failure location; classify error type (runtime, logic, integration, config, dependency).
-- Differential diagnosis: 2-3 hypotheses; cheapest check first; eliminate until one remains.
-- Bisect (complex only, gate: insufficient stack/blame): git bisect/manual search; check side effects (shared state, race, timing).
-- Mobile Debugging: platform-specific symbolication and log analysis.
-- Synthesize: root cause, fix recommendations, prevention (tests, patterns, monitoring).
+- Localize
+  - Start from the reported symptom/error.
+  - Identify the failing component, operation, and relevant code path.
+  - Gather only evidence directly relevant to the failure.
+  - If the cause is already obvious, skip further diagnosis.
+- Explain
+  - Form the most likely cause from the available evidence.
+  - Create alternative hypotheses only when the evidence is ambiguous.
+  - Prefer the simplest explanation consistent with the evidence.
+- Verify
+  - Perform the cheapest, highest-signal check first.
+  - Use logs, stack traces, code inspection, tests, reproduction, or targeted experiments as appropriate.
+  - Stop once the cause is sufficiently established.
+  - Do not run checks that cannot change the diagnosis.
+- Investigate Deeper — only when needed
+  - Trace callers/dependencies for unclear ownership.
+  - Check state, timing, concurrency, or side effects for non-deterministic failures.
+  - Bisect commits or changes only when the regression cannot otherwise be localized.
+  - Use platform-specific tooling only when the platform is relevant.
 - Output: minimal JSON per `output_format`.

 ### Execution

+- Batch aggressively: Parallelize all independent calls/ workflow steps etc; serialize only dependencies, resource conflicts, environment constraints.
+- Follow applicable workflow steps only.
 - Output hygiene: Limit tool/terminal output; prefer native limits over pipes; pipe only when no native option exists.
 - Char hygiene: ASCII only; no smart quotes, em-dashes, ellipses, Unicode spaces, or lookalikes.
-- Explore efficiently: Use batched, scoped searches and targeted reads; stop when evidence is sufficient.
-- Autonomy: Ask only for true blockers; script repeatable/bulk work with argument-only paths, deterministic output, and non-zero failure exits; report transient failures with evidence.
-- Ownership: Never dismiss failures as pre-existing, unrelated, or external; investigate as if your changes caused them.
-- Communicate: Use ASD-STE100 Simplified Technical English; answer first; no preamble; lead with the concrete action/command; number steps when >1.
+- Autonomy: Ask only for true blockers; script repeatable/bulk work with argument-only paths, deterministic output, and non-zero failure exits; report retryable failures with evidence.

 ### Constitutional
 
-- Prefer maintained official/in-stack libraries to custom code.
-- Diagnose only; never fix or guess root causes.
-- If reproduction fails, return `failed`/`needs_revision` with evidence and next steps.
-- If the configured memory store contains `d:{error_sig}`, read it before diagnosis. Reuse a cached root cause only when its match score is at least 0.8. Replace it only with a revalidated finding whose confidence is at least 0.85.
-- Stay read-only. Validate reproduction evidence, traces, and diagnosis. Do not run post-edit checks.
-- For non-trivial tasks, validate assumptions, edge cases, risks, contradictions, and alternatives stepwise.
-- If `error_context` is vague, under 10 words, or lacks a stack trace, error message, failing test, or reproduction steps, ask for steps, actual/expected results, and constraints.
-- For missing context, return `status: needs_revision`, `clarification_needed: true`, and specific questions.
-- Recommend lint rules only for recurring cross-project patterns, e.g. unsafe null handling or hardcoded values.
+- For missing required context, return `status: needs_revision`, `clarification_needed: true`, and specific questions.
+- Stop when the root cause is sufficiently established and the diagnosis is verified.
+- Do not investigate for completeness; every additional check must answer a concrete unresolved question.
