Teach doc-syncer to sync an existing ROADMAP.md without ever creating one.
- ROADMAP absent → propose nothing; never bootstrapped (creation belongs
to init/onboard skills). Never enters DOC_MISSING, never a CREATE
candidate.
- ROADMAP present → standard drift detection plus 'shipped reconciliation':
a planned/unchecked item proven delivered by CODE + git is proposed for
the shipped/done section (or checkbox), preserving wording. [AUTO] when
the item-to-code mapping is obvious, [HUMAN] when it needs judgment.
One direction only (planned -> shipped); never invent planned items.
- Forbid reading .claude/tasks/ (or any .claude/) to populate or check
ROADMAP; shipped status is deduced from code/git only.
- Numeric incoherence (e.g. a '22/22' milestone matching no code counter)
is surfaced as a [HUMAN] question, never overwritten with a guess.
Implements BDR-022's read-only .claude/ boundary for the ROADMAP case.
