 | ERR-064 | Western cross-system support accepted external JSON but did not calculate a tropical natal chart from standard birth input, inviting agents to treat missing Western data as a completed cross-check. | mitigated 2026-07-14 | `western_chart_engine.py` computes Swiss Ephemeris tropical natal evidence for direct-chart/rectification only. It remains `partial` until separately materialized timing evidence exists; Prashna and external-payload precedence are regression-tested. |
 | ERR-065 | A newly added release-critical script can be absent from a zip before its first Git commit because the package enumerates tracked files only. | mitigated 2026-07-14 | List `scripts/western_chart_engine.py` in `REQUIRED_CONTRACTS`; the release-package test proves both editions include it before commit. |
 | ERR-066 | The pre-work fragment sweep invoked a retired `audit-capabilities --mode strict` contract, so governance tests and the mandatory preflight failed before real checks ran. | mitigated 2026-07-14 | Invoke the supported `--mode validate`; `tests/test_preflight_fragment_scan.py` and `pre_work_check.py` must remain green before substantive work. |
-| ERR-067 | A generic “Western timing” label can imply secondary progressions, solar arcs, and returns that have not been computed. | mitigated 2026-07-14 | Native timing accepts explicit `transit_date` and `solar_return_year` only; packet boundaries and premium prompts name every unsupported technique. |
