Summary

The tri-state inspectInstallation introduced in #1197 stats every path in the lockfile's file list to detect a truncated install. That list includes compiled bundles under .swamp/bundles/**, .swamp/vault-bundles/**, .swamp/driver-bundles/**, .swamp/datastore-bundles/**, and .swamp/report-bundles/** — regenerable build artifacts, not source.

When a user clears any of those caches (normal hygiene, stale rebuild, fresh worktree), auto-resolve flipped from intact → truncated and emitted:

incomplete — missing 1 file(s): ".swamp/bundles/91139983/system_usage.js"

…instead of the alreadyInstalledButFailed ("already installed at … run --force to recover") path that protects user WIP per #121. The motivating swamp-club#133 symptoms are all source-tree artifacts (manifest, kind subdirs, declared source), so the fix is to scope the truncation predicate to source files only.

This filters bundle prefixes out of the stat loop in inspectInstallation. Prefixes are derived from SWAMP_SUBDIRS.{bundles, vaultBundles, driverBundles, datastoreBundles, reportBundles} so a future bundle-dir addition stays in sync. No filesystem mutation, no API/event/wire-format changes.

Test Plan

• deno fmt --check, deno lint, deno check clean
• src/cli/auto_resolver_adapters_test.ts — 18/18 pass, including 2 new regression cases:
  • inspectInstallation ignores absent bundle artifacts and stays intact (covers all 5 bundle subdirs)
  • inspectInstallation reports truncated only for missing source, not missing bundles
• integration/auto_resolver_truncated_test.ts — passes (fix(extensions): detect truncated pulled-extension trees in auto-resolve (swamp-club#133) #1197/feat: add Definition entity with CEL expression support (#117) #133 source-truncation behaviour preserved)
• integration/auto_resolver_no_clobber_test.ts — passes (Issue 6: Migrate echo model to new architecture #121 no-clobber invariant preserved)
• deno run compile succeeded
• End-to-end repro against the rebuilt binary: swamp extension pull @stack72/[email protected] → edit pulled .ts with WIP marker + syntax error → rm -rf .swamp/bundles → swamp model create @stack72/system-usage instance1 now produces:

  Extension "@stack72/system-extensions" is already installed at … but failed to load.
  Local edits may be preventing it from registering — inspect the source and fix errors.
  To reset to the registry version and discard local changes, run: swamp extension pull "@stack72/system-extensions" --force
  

  …instead of the buggy incomplete — missing 1 file(s): ".swamp/bundles/91139983/system_usage.js".
• UAT tests/cli/extension/pull_wip_preservation_test.ts:156 in swamp-uat (CI gate — local run blocked by membership auto-trust collision unrelated to this fix)
