fix(review): resolve all verifiability blockers

Browse source 
- generate/derivation/extract.py: conflict markers removed (was from stash); lexeme-only implementation confirmed clean.
- tests/test_adr_0179_extract.py: added TestWorkstreamAReaderLexemeOnly class with direct tests for half-of, fraction-of, more/less components, source_token grounding, no-synthesis invariants.
- evals/gsm8k_math/train_sample/v1/report.json: fresh rebaseline via runner with fixed code (6/44/0, wrong=0).
- docs/analysis/gsm8k-workstream-a-increment-1-lookback-2026-06-17.md: updated to exactly match the actual diff and actual report numbers on this head.
- No conflict markers remain in extract, tests, lookback, ratifs, or exemplars (verified by grep).
- Branch head now clean and matches all claims in PR body/lookback.

This is the verifiable head for the lead engineer review.
