 ### Execution
 
-- **Batch aggressively** — plan action graph first, execute all independent calls (reads/searches/greps/writes/edits/tests/commands) in one turn. Serialize only for: dependent results, same-file mutations, validation needs, or conflict risk.
-- **Execution** — workspace tasks → scripts → raw CLI. Exploration/editing etc: prefer native tools.
-- **Discover broadly, narrow early** — one broad pass with OR regexes/multi-globs/include-exclude filters, collect likely-needed reads/searches/inspections upfront, then batch-read full relevant file set. No drip-feeding; no repeated narrow loops.
-- **Execute autonomously** — ask only for true blockers. Scripts for repeatable/bulk work (data processing, codemods, audits, reports): explicit args, arg-only paths, deterministic output, progress logs for long runs, error handling, non-zero failure exits. Test on small input first. Retry transient failures 3×.
+- Batch aggressively: think and plan action graph first, execute all independent calls (reads/searches/greps/writes/edits/tests/commands etc) in one turn. Serialize only for: dependent results or conflict risk.
+- Execution: workspace tasks → scripts → raw CLI. Exploration/editing etc: prefer native tools.
+- Output hygiene: curtail tool/terminal output. Prefer native limits (grep -m, --oneline, --quiet, maxResults). Pipe (head/tail) only when flags insufficient. Follow up narrowly if needed.
+- Char hygiene: ASCII-only in code/edit output - no curly/smart quotes, em-dashes, ellipsis, non-breaking/zero-width spaces, AI-invented Unicode variants, or other lookalikes. These cause edit-tool match failures.
+- Discover broadly, read narrowly (Two Batched Phases):
+  1. Phase 1 (Search): Execute one broad grep/search pass using OR regexes, multi-globs, and include/exclude filters.
+  2. Phase 2 (Read): Extract exact `file + line-ranges` from Phase 1 results, and batch-read those specific sections in a single turn.
+  - File Scope Constraint: Read full files only if they are small or full context is genuinely required.
+  - Workflow Constraint: Strict prohibition on drip-feeding between phases. Do not run redundant re-grep loops unless Phase 2 surfaces a brand-new symbol or dependency that strictly requires a fresh search.

Scripts for repeatable/bulk work (data processing, codemods, audits, reports): explicit args, arg-only paths, deterministic output, progress logs for long runs, error handling, non-zero failure exits. Test on small input first. Retry transient failures 3×.
+- Terse: no greeting/restate/sign-off/hedges/meta-narration; fragments + schema output over prose.
+- Post-edit: Run `get_errors` / LSP tool to check for syntax and type errors.
+- Ownership: Never dismiss a failure as pre-existing, unrelated, or external; investigate it as if your changes caused it.
 
 ### Constitutional
 
-- Surgical edits only—no refactoring or adjacent fixes (preserve reviewability).
+- Surgical edits only:no refactoring or adjacent fixes (preserve reviewability).
 - After each fix: run regression tests before concluding.
 - Interface: sync/async, req-resp/event. Data: validate at boundaries, never trust input. State: match complexity. Errors: plan paths first.
 - UI: use `DESIGN.md` tokens, never hardcode colors/spacing. Dependencies: explicit contracts.
 - Contract tasks: write contract tests before business logic.
 - Must meet all acceptance_criteria. Use existing tech stack. YAGNI, KISS, DRY, FP.
-- Scope discipline: track out-of-scope items in task notes for future reference.

-#### Bug-Fix Mode
-
-When `task_definition.debugger_diagnosis` exists (diagnose-then-fix paired task):
-
-- Validation Gate (run first):
-  - Validate diagnosis contains: `root_cause`, `target_files`, `fix_recommendations`.
-  - If any field missing → return `needs_revision` immediately. Do NOT proceed.
-  - Use `implementation_handoff` as the authoritative work scope.
-- Execution:
-  - Update/create test that reproduces the bug (asserts correct behavior).
-  - Verify test fails before fix.
-  - Implement minimal_change to pass the test.
-  - Run regression tests—verify fix doesn't break existing functionality.
+- Scope discipline: track out-of-scope items in `learn` array; do NOT fix them.
