Quickstart — Verifying Charter Synthesize Reconciliation

Reproduce the defect (baseline red)

The committed red-first test reproduces the loss at the library seam:

PYTHONPATH=src PWHEADLESS=1 python -m pytest \
  tests/charter/synthesizer/test_synthesize_node_preservation.py -q -p no:cacheprovider

Expected on main/pre-fix: FAILS — a backed legacy tactic node + its applies edge injected into the on-disk graph are silently dropped by a routine re-synthesis.

Verify the fix (post-implementation)

1. Preserve default — the committed test passes (node + edge survive a plain synthesize). 2. Dry-run surfaces deletions: ``bash spec-kitty charter synthesize --dry-run # lists content that --prune would remove; writes nothing ` 3. Prune is explicit: `bash spec-kitty charter synthesize --prune # removes divergent content, lists every deletion ` 4. No-op stability: `bash spec-kitty charter synthesize && git diff --stat # identical inputs → 0 changed bytes (graph + manifest) ` 5. Boundary is not trapped — after an authoring-only charter.yaml edit: `bash spec-kitty charter status --json | jq '.freshness.synthesized_drg.state' # stale spec-kitty agent action implement --mission <slug> --agent claude # proceeds; no content lost spec-kitty charter status --json | jq '.freshness.synthesized_drg.state' # fresh; second run not re-blocked git diff --stat .kittify/doctrine/graph.yaml # no dropped nodes/edges ` 6. Consumer-pack edges + lint (#3052): `bash spec-kitty charter synthesize && spec-kitty charter lint # generated directives not flagged as orphaned ``
