 MODEL: GPT-5.4-codex
-REASONING: low
+REASONING: high
 
 COMMAND:
-1. Update roadmap:
-   Track F → set "verify all samples still function correctly" to [.]
-2. Do not modify any other items
-3. Package ZIP
+1. Open:
+   tests/samples/SamplesProgramCombinedPass.test.mjs
+
+2. Locate phase expectation assertion.
+
+3. Replace hardcoded phase list:
+   phase-01 → phase-15
+
+4. Update to:
+   include phase-16, phase-17, phase-18, phase-19
+
+   Preferred:
+   derive phases dynamically from filesystem OR
+   extend static list to 19
+
+5. Run:
+   node ./scripts/run-node-tests.mjs
+
+6. Confirm:
+   SamplesProgramCombinedPass passes
+
+7. Package ZIP:
+   <project folder>/tmp/BUILD_PR_LEVEL_19_7_FIX_SAMPLE_PHASE_EXPECTATION.zip
+
+CONSTRAINTS:
+- Do not modify unrelated tests
+- Do not change engine/runtime code
+- Smallest scoped change only

+# Fix Sample Phase Expectation
+
+## Problem
+Test expected phases only up to phase-15.
+
+## Fix
+Updated expectation to include phase-16..19.
+
+## Result
+Unblocks test suite and Level 19 progression.

+# BUILD_PR_LEVEL_19_7_FIX_SAMPLE_PHASE_EXPECTATION
+
+## Purpose
+Fix failing validation blocker:
+SamplesProgramCombinedPass.test expects phase-01..15 but repo now includes phase-16..19.
+
+## Scope
+- Single purpose PR: fix sample phase expectation mismatch
+- Test + expectation alignment only
+- No feature work
+
+## Required Change
+Update:
+tests/samples/SamplesProgramCombinedPass.test.mjs
+
+Replace:
+expected phases = phase-01..phase-15
+
+With:
+dynamic or explicit inclusion of:
+phase-01..phase-19
+
+## Validation
+Run:
+- node ./scripts/run-node-tests.mjs
+EXPECT:
+- SamplesProgramCombinedPass passes
+
+## Acceptance
+- Test suite passes this test
+- No regressions introduced
+- Unlocks multiple Level 19 tracks
