Context

RemoteClaw is middleware that delegates LLM execution to CLI agents (Claude Code, Gemini, Codex, OpenCode). The CLI agents own LLM API communication, including per-provider message-transcript formatting (how to sanitize tool_call_ids for Google, how to order turns for Gemini, how to preserve thinking signatures for Anthropic, etc.).

src/agents/transcript-policy.ts contains resolveTranscriptPolicy(...) — a function that returns a TranscriptPolicy object describing how to sanitize a transcript for a specific LLM API protocol. Its input parameters (modelApi, provider, modelId) are concerns middleware doesn't have: RemoteClaw doesn't speak LLM API protocols. It relays messages to CLI subprocesses that speak their own CLI-stdio protocols (ACP, Claude Code JSON stream, etc.), which are already abstracted over LLM-API specifics.

This is platform concern masquerading as middleware code. Leftover from the pre-fork embedded execution path.

Problem

Live-by-attestation, dead-by-consumption

• src/agents/transcript-policy.ts:10-12 declares MODULE_ATTESTATIONS = { resolveTranscriptPolicy: "live" } (enforced by scripts/check-attestations.mjs — the attestation-gate CI check).
• src/agents/transcript-policy.test.ts exercises resolveTranscriptPolicy with 13+ test scenarios.
• Zero production callers. Exhaustive search:

  rg -n "resolveTranscriptPolicy" src/ ui/ extensions/ apps/ --type ts -g '!*.test.ts'
  # Returns only the declaration itself

• The gateway, middleware, and auto-reply paths have zero references to transcript-policy or resolveTranscriptPolicy.

The attestation says "live" but no production code consumes the function. This is an inconsistency: the attestation system records intent, not actual wiring, and here intent has outlived relevance.

The isGoogleModelApi stub at line 14 makes Google policies unreachable

transcript-policy.ts:14 defines a module-local stub:

const isGoogleModelApi = (..._args: unknown[]): boolean => false;

Introduced in #2303 / merge #2333 (gut(stubs): sweep gutted CLI/command/agent stubs and clean up consumers). This stub shadows the REAL isGoogleModelApi function in src/agents/agent-helpers/google.ts (which agent-helpers.ts re-exports). Because the local stub always returns false, every Google-specific branch in resolveTranscriptPolicy is permanently dead:

• isGoogle = false always → applyGoogleTurnOrdering, validateGeminiTurns, Gemini thought-signature sanitization never activate for Google models.

This would be a genuine bug if the function were wired — but it isn't. It's bug-free-by-death. No need to fix the stub because the whole function goes away.

Imports are shared utilities, NOT orphaned by removal

• import { normalizeProviderId } from "./provider-utils.js" → provider-utils.ts has 20+ importers across auth/, agents/, commands/, cron/. Not orphaned.
• import type { ToolCallIdMode } from "./tool-call-id.js" → tool-call-id.ts has 5+ importers (agent-helpers, session-transcript-repair, agent-helpers/images). Not orphaned.

Scope is cleanly bounded to the file + its test.

Non-goals

• Don't fix the isGoogleModelApi stub by importing the real function. The file is being deleted; repairing the stub would be dead work.
• Don't preserve the attestation entry. Removing the file removes its attestation declaration; scripts/check-attestations.mjs scans dynamically and won't complain about a non-existent file.
• No LEGACY_CONFIG_RULES / migration. This is not a config field — it's a source module. File deletion is the migration.
• No backward-compat shim. No code depends on the exported symbol.

Tasks

1. Delete src/agents/transcript-policy.ts (146 lines).
2. Delete src/agents/transcript-policy.test.ts.
3. Run pnpm tsgo and pnpm lint to confirm no broken imports (expected: none, since no production code imports from this file).
4. If the post-build scripts (scripts/post-build.mjs or similar) reference transcript-policy specifically, remove those references. Verify via rg -n "transcript-policy" scripts/.

Acceptance Criteria

• src/agents/transcript-policy.ts does not exist.
• src/agents/transcript-policy.test.ts does not exist.
• rg -n "transcript-policy" src/ ui/ extensions/ apps/ scripts/ returns only references in this issue's body (none in code).
• rg -n "resolveTranscriptPolicy" src/ returns no hits.
• rg -n "TranscriptPolicy\\b" src/ returns no hits (the exported type also dies with the file; nothing consumes it).
• pnpm tsgo clean.
• pnpm lint clean.
• pnpm test passes with fewer tests (the 13+ test cases in transcript-policy.test.ts are gone; net decrease expected).
• All required CI gates pass: rebrand-gate, zombie-import-gate, stub-debt-gate, throwing-stub-callers-gate, obsolescence-audit-gate, attestation-gate (the attestation-gate should be happy because the file's MODULE_ATTESTATIONS is gone along with its exports), docs, build, test, lint.

Out of scope

• src/agents/provider-utils.ts and src/agents/tool-call-id.ts — both remain actively used by unrelated code paths. Separate decisions if/when those become orphaned.
• Any other zombie module with "live" attestation but zero production callers. A broader zombie-attestation audit is a separate concern; this issue fixes only the one specific case observed during the gut(config): remove remaining LLM-platform z.unknown() stubs — middleware-not-platform consolidation #2489 audit.
