+## Intent
+
+<!-- What is broken or missing, and why it matters. Then the high-level approach — the "what", not the "how". -->
+
+**Problem:** ONE_TO_TWO_SENTENCES
+
+**Approach:** ONE_TO_TWO_SENTENCES
+
+## Boundaries & Constraints
+
+<!-- Three tiers: Always = invariant rules. Ask First = human-gated decisions. Never = out of scope + forbidden approaches. -->
+
+**Always:** INVARIANT_RULES
+
+**Ask First:** DECISIONS_REQUIRING_HUMAN_APPROVAL
+<!-- Agent: if any of these trigger during execution, HALT and ask the user before proceeding. -->
+
+**Never:** NON_GOALS_AND_FORBIDDEN_APPROACHES

+## Code Map
+
+<!-- Agent-populated during planning. Annotated paths prevent blind codebase searching. -->
+
+- `FILE` -- ROLE_OR_RELEVANCE
+- `FILE` -- ROLE_OR_RELEVANCE
+
+## Tasks & Acceptance
+
+<!-- Tasks: backtick-quoted file path -- action -- rationale. Prefer one task per file; group tightly-coupled changes when splitting would be artificial. -->
+<!-- If an I/O Matrix is present, include a task to unit-test its edge cases. -->
+<!-- AC covers system-level behaviors not captured by the I/O Matrix. Do not duplicate I/O scenarios here. -->
+
+**Execution:**
+- [ ] `FILE` -- ACTION -- RATIONALE
+
+**Acceptance Criteria:**
+- Given PRECONDITION, when ACTION, then EXPECTED_RESULT
+
+## Spec Change Log
+
+<!-- Append-only. Populated by step-04 during review loops. Do not modify or delete existing entries.
+     Each entry records: what finding triggered the change, what was amended, what known-bad state
+     the amendment avoids, and any KEEP instructions (what worked well and must survive re-derivation).
+     Empty until the first bad_spec loopback. -->
+
+## Design Notes
+
+<!-- If the approach is straightforward, DELETE THIS ENTIRE SECTION. Do not write "N/A" or "None". -->
+<!-- Design rationale and golden examples only when non-obvious. Keep examples to 5–10 lines. -->

+DESIGN_RATIONALE_AND_EXAMPLES
+
+## Verification
+
+<!-- If no build, test, or lint commands apply, DELETE THIS ENTIRE SECTION. Do not write "N/A" or "None". -->
+<!-- How the agent confirms its own work. Prefer CLI commands. When no CLI check applies, state what to inspect manually. -->
+
+**Commands:**
+- `COMMAND` -- expected: SUCCESS_CRITERIA
+
+**Manual checks (if no CLI):**
+- WHAT_TO_INSPECT_AND_EXPECTED_STATE
