Bilateral SYNERGY/UPSTREAM reconciliation across sibling projects. Use when the user wants to sync sibling SYNERGY/UPSTREAM files, compare both sides to surface drift, find reciprocation gaps (entries here but not there, or vice versa), flag stale-aligned rows, detect status drift across sides, surface friction the sibling tracks ABOUT this project (their UPSTREAM- .md), or apply a reciprocation batch with --auto-reciprocate. Workflow 3 covers two UPSTREAM pairing modes: shared third-party dependencies AND reciprocal sibling-friction pairs (UPSTREAM- .md here ↔ UPSTREAM- .md there). NOT for logging entries on this side (use /synergy-tracker workflow 1 (Log a synergy entry)) — sibling-sync compares both sides without writing by default. NOT for upstream → project drift (use /vendor-sync); sibling-sync handles peer-to-peer drift between sibling vp- projects.

Bilateral SYNERGY/UPSTREAM reconciliation across sibling projects. Use when the user wants to sync sibling SYNERGY/UPSTREAM files, compare both sides to surface drift, find reciprocation gaps (entries here but not there, or vice versa), flag stale-aligned rows, detect status drift across sides, surface friction the sibling tracks ABOUT this project (their UPSTREAM-<this-project>.md), or apply a reciprocation batch with --auto-reciprocate. Workflow 3 covers two UPSTREAM pairing modes: shared third-party dependencies AND reciprocal sibling-friction pairs (UPSTREAM-<sibling>.md here ↔ UPSTREAM-<this-project>.md there). NOT for logging entries on this side (use /synergy-tracker workflow 1 (Log a synergy entry)) — sibling-sync compares both sides without writing by default. NOT for upstream → project drift (use /vendor-sync); sibling-sync handles peer-to-peer drift between sibling vp-* projects.
