BUG: deployed amico verb-router bundle goes stale — nothing rebuilds the dist on upgrade

[aarontrowbridge]

Important

Problem — The deployed amico verb-router bundle on the server went 46 days stale (built Jul 15) while its source moved a month ahead: the ledger verbs shipped in source were absent from the deployed binary, so every ledger call on that machine silently degraded to "no ledger history" — for weeks, with no signal anywhere. Compounding it: nothing in CI builds this bundle (a broken entry or unresolvable import would pass CI green), and a stale checkout that skips install can't even build it locally.
Approach — Make bundle staleness structurally impossible: (1) a CI lane that builds all three bundles from current source on every push, failing on any broken entry or unresolvable import; (2) hook the bundle build into the existing upgrade path (the upgrade-receipt server-binary machinery) so every deployed upgrade refreshes the dists and writes a receipt — deployed freshness must not depend on whoever last ran a local build. Also fix the module-type warning on the extension-side bundle copy (ESM bundle under a package.json without a module type — every invocation pays a reparse).
Scope — in: CI build lane, upgrade-path rebuild hook + receipt, the module-type cosmetic · out: the verb surface, launcher scripts, bundle contents.

Acceptance Criteria

• CI builds all three bundles from source and fails on a broken entry or unresolvable import
• The upgrade path rebuilds + deploys the dists with a receipt (a deployed upgrade can no longer leave a stale verb router behind)
• Invoking the extension-side bundle emits no module-type reparse warning

Testing Decisions

Extend the existing packaging/upgrade test suites for the rebuild-hook receipt; the CI build lane mirrors the vsix-gate's job pattern rather than inventing a new one.

Prior Art

The upgrade-receipt machinery (server-binary upgrade lane + receipts journal) is the hook to extend; the esbuild config builds all three bundles in one pass and is the build entry.

Notes

Evidence 2026-08-30, skill-health campaign (session-20260830-skill-health §7): deployed bundle predated the ledger verbs; amico ledger answered "unknown verb" for weeks; zero ledger references in the stale bundle vs 81 in a fresh build of identical source. Dists refreshed by ops 2026-08-30 (rebuild + both-copy deploy + PATH verify); this issue is the systemic follow-through. Part of the skill-health campaign, Phase 0.3.
