Why

Antony's goal: delete every AntelopeJS guardrails.ratchet.json through verified PRs on campaign/integration, each contract change proven by tarball against every consumer, with no fallback. interface-api#68 defaults ControllerClass to object, so interface-data-api no longer compiles: it indexes controller instances by string in ten places (Checks: 7 passed, 2 failed. in the proof against the tarball).

What changed

• Pins interface-api fcc62d2 (producer ref fcc62d229e78d7584ec696495cff2bafe32d5e24, sha256 1a29379d519467fdd438ee411a93519956f1e024d4f457f0d447cac67af61099, packed 0.3.0).
• fieldsOf(instance) in src/internal/prototypes.ts narrows a controller instance to the existing RowFields, whose values are unknown. Reads of meta.modelKey and modifier key fields, and the writes on the { ...obj } copy, go through it. It returns the same object, so inherited accessors still run on the instance.
• c.prototype[key] = func becomes Object.assign(c.prototype, { [key]: func }), which performs the same [[Set]].
• A test covers own fields, inherited accessors, an absent field and the refusal.

Proofs

• pnpm run checks in CI state, after merging integration 65afb35 (chore(ratchet): delete the interface-data-api guardrail ratchet #85, ratchet deleted): Checks: 8 passed, 0 failed.
• Surface diff against integration: one added @internal declaration, fieldsOf in dist/internal/prototypes.d.ts; runtime export keys identical: 4 entries. api-diff cannot judge this PR because its base half does not build against the new pin (TS7053 in the base worktree).

Attention

• fieldsOf adds no new dictionary type or suppression: RowFields carries the counted disable chore(ratchet): delete the interface-data-api guardrail ratchet #85 landed. It is named for table rows and used here for controller fields, because both hold values of unknown type. A verifier should judge that reuse.
• holdsFields narrows to RowFields after only an object check. That holds because any object answers any string key.
• fieldsOf throws for a function, where the old index read did not. A controller instance is never a function.
