What this changes

Six brittle tests now derive their expectations from the command registry, BUNDLE_SKILLS, model-floor.json and the real exported functions instead of literal lists, counted matches in main.ts or prose. A new test/helpers/source-blocks.ts locates a function body or IPC handler by bracket matching, so wiring tests check where a call sits.

Key files

• test/editor-demand-wiring.test.ts — contract: the editor server is requested only from the need-editor and restart handlers, launchEditor only through the demand gate, keepWarm only in the scan. Fails if a request() is dropped from a handler or appears anywhere else, if launchEditor is called directly, or if keepWarm leaves runScan.
• test/lantern-permissions-triggers.test.ts — contract: saving the skill linker or importing a list syncs the project's delegate rules afterwards, and a cancelled picker does not. Now calls the real registerExtensionsIpc with fakes; fails if either handler drops or reorders the sync, or main.ts stops passing syncPermissionsFor.
• test/lantern-macro-load.test.ts — contract: lantern:macro is behind fromWorkspace, checks isRegisteredDir, and carries the language from renderer to reader. Literal 14 blocks / 58 edges removed (the view is compared to the fixture view). Fails if the wrapper, the registered check or the lang argument goes.
• test/project-window.test.ts — contract: every registry command except on-demand ones is registered after boot. The 20-name list is now COMMANDS; fails if a registerCommand is removed.
• test/install-skills.test.ts — contract: every bundled skill is installed. The 16-name list is BUNDLE_SKILLS, which must equal the skills/*/SKILL.md folders; fails if a skill is dropped from the bundle.
• test/lantern-sync-selftest.test.ts — contract: the mapping model policy accepts the floor's families and exact ids, advises below the recommended version, rejects the rest. Driven by model-floor.json and the CLI; fails if the advisory or the allow check in lib.mjs breaks.

Before / after

Before: expect([...MAIN.matchAll(/editorDemand\.request\(\)/g)]).toHaveLength(2) and a hand-written command list. After: every editorDemand.request( lies inside the two handlers, and COMMANDS supplies the list.

Verified with pnpm install --frozen-lockfile, pnpm run typecheck, pnpm run lint, pnpm test, all green; each contract was also broken in source and the new test failed. Unreviewed fixes: none. Lantern: 7 files re-mapped.
