* Cross-rung identity (F5, spec §6.3 fork c): `email` is git's own join key —
|
|
* forges already map email → account. Resolved from the workspace git config,
|
|
* cached per root, FAIL-OPEN: absence just omits the optional field and the
|
|
* sidecar stays valid (spec §6.9). vscode-free, so it is unit-testable.
