ci: align the zero-leak check to the charter symbol set#449
Conversation
Scan the runtime sources for the charter set only (nexum:intent, value-flow, VenueAdapter, synthesize_venue, nexum:adapter, PoolRouter), dropping the loose word-shape sweep that false-flagged the opaque extension-map fixtures; keep the crate-graph and WIT-leaf checks, and state the invariant in the nexum-runtime crate charter. The CI job stays advisory until the physical repo cut.

The false-positive problem this PR fixes (Cow/intentional needing carve-outs, scanning the whole crate dir) is real and worth fixing, but the specific fix trades false positives for false negatives on the current vocabulary. Three of the six charter symbols — nexum:intent, nexum:adapter, PoolRouter — were already renamed away in #428 (to videre:types, folded into videre:venue, and VenueRegistry respectively) and then relocated entirely out of nexum-runtime in #447. Checking for them now is checking for names that can never reappear, since they no longer exist anywhere in the codebase to leak.
More importantly, the current post-rename vocabulary that would actually indicate a real leak — videre:types, videre:venue, VenueRegistry, VenueActor, VenueId — isn't in the charter list at all (only VenueAdapter, a distinct trait name, and the substring value-flow, which happens to still match videre:value-flow, survive by coincidence). Concretely: if a future change reintroduced use videre_host::VenueRegistry into crates/nexum-runtime/src, exactly the regression this check exists to catch, this scan would report a clean pass. Since git blame/history on this check isn't the point — the invariant it's meant to enforce is about the current naming, not the pre-rename one. Worth updating the charter set to the post-rename names (videre:|VenueRegistry|VenueActor|VenueId|VenueAdapter, or similar) rather than the retired ones.

What
Narrows the venue-agnostic CI scan from a broad venue-vocabulary regex to the curated charter symbol set (
nexum:intent|value-flow|VenueAdapter|synthesize_venue|nexum:adapter|PoolRouter), scopes it tocrates/nexum-runtime/src, and documents the zero-leak charter in the crate's top-level rustdoc.Why
The old regex over-matched (
Cow,intentional, etc. needed manual carve-outs) and scanned the whole crate directory instead of just sources. A curated symbol set tied to the actual forbidden names keeps the scan precise and stops opaque extension payloads from false-flagging, per the M2 zero-leak invariant.Closes #384
