The operator, 2026-10-25: only if a module has a new version in commit x is a new value written naming commit x. A merge
wrote every module of the repository at the new commit, fingerprint unchanged (about 186 keys per mesh-catalog merge), and
the controller's take-in took each in again: twice tonight it flooded. Now a merge that gives a module the value it holds
but for the commit writes nothing, and the value keeps the commit its fingerprint first appeared at. The kind: a write
that differs only in where it was computed. The other instance, a source revision re-stamping Src on every module at its
repository's head after any merge anywhere, now stamps Src once. The trunk head stays the gate's source.main.
I1: a merge writes each module its manifests name, at its directory. I2: a pull request's changed directory, a
preview's touched module and a source revision's modules come from the modules bucket (a module a pull request adds is
found in the preview by its manifest). I4: the value of today's form (fp, none) is no longer written, since it was
computed from the build records; mesh-sdk keeps it readable until R4g. One commit: the three share applyMerged and its
tests. Pins mesh-sdk feat/r4e-sdk 9cb4d59.
