 - 2026-04-05: Closed PR `#1232` after full audit. The proposed `skill-scout` workflow overlaps current `search-first`, `/skill-create`, and `skill-stocktake`; if a dedicated marketplace-discovery layer returns later it should be rebuilt on top of the current install/catalog model rather than landing as a parallel discovery path.
 - 2026-04-05: Ported the safe localized README switcher fixes from PR `#1209` directly into `main` rather than merging the docs PR wholesale. The navigation now consistently includes `Português (Brasil)` and `Türkçe` across the localized README switchers, while newer localized body copy stays intact.
 - 2026-04-05: Salvaged the reusable Hermes-generated operator workflow lane without replaying the whole branch. Added six ECC-native top-level skills instead of the old nested `skills/hermes-generated/*` tree: `automation-audit-ops`, `email-ops`, `finance-billing-ops`, `messages-ops`, `research-ops`, and `terminal-ops`. `research-ops` now wraps the existing research stack, while the other five extend `operator-workflows` without introducing any external runtime assumptions.
+- 2026-04-05: Added `skills/product-capability` plus `docs/examples/product-capability-template.md` as the canonical PRD-to-SRS lane for issue `#1185`. This is the ECC-native capability-contract step between vague product intent and implementation, and it lives in `business-content` rather than spawning a parallel planning subsystem.
