Conversation
A practical reference for propagating a numeric-stack change across the three repos: repo roles (numerics is master), the per-family/per-loom mirror layout, the vere64 vere/ vs vere64/ split, why cross-repo header diffs are noisy (per-family mirrors vs full vere trees -> trust the .c by byte-identity), the refcount-linter bar (u3_weak / @refcount, 0 findings strict-weak), the forward and back-port sync workflows, worktree-build mechanics, and the "trace provenance, Hoon is ground truth" rule.

AGENTS.mdat the repo root: a practical guide for an agent (or human) propagating a numeric-stack change across urbit/numerics, urbit/urbit, and urbit/vere.Motivated by this session's sync work (unum/#79, math/#80), which surfaced several non-obvious hazards worth writing down:
pkg/arvo/lib/); urbit/vere compiles the jets. Fixes usually flow out of numerics, but sometimes land in a vere PR first and must be mirrored back.<fam>/vere/(pre-vere64,c3_w, variadicu3r_mean) vs<fam>/vere64/(post-vere64,c3_h, bracedu3r_mean). A fix goes to both; loom-agnostic edits are byte-identical, loom-specific lines differ only in those two respects. lagoon is being collapsed to one mirror.q.h/w.h/<kelvin>/tree.cpull in unrelated families. Trust the family.cby byte-identity; normalizeu3_weak↔u3_nounto isolate real deltas.u3_weaktyping +@Refcountannotations, 0 findings under--strict-weak..git-file symlink workaround), and the provenance rule (Hoon is ground truth; trace "the spec says …" before trusting it — cf. the fabricated C-fmod%mod).Draft — easy to amend; corrections welcome on the PR.
