From 57593ca7348e02203df32273d81bf6c9e8492688 Mon Sep 17 00:00:00 2001 From: ste-bah Date: Mon, 27 Apr 2026 17:06:52 +0100 Subject: [PATCH] fix(spoof): CCH x-anthropic-billing-header + complete auto-discovery (v0.1.15+v0.1.16) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit After 2 weeks of agent-launch failures and four wrong-theory hotfixes, side-by-side comparison with claurst (third-party Rust port of Claude Code) revealed the actual root cause: archon-cli's spoof was missing the Claude Code billing/anti-spoof header. Anthropic was returning 429 with no retry-after (matching the fallback default in classify_error) — not a real rate limit, but Anthropic rejecting our request as an invalid Claude Code attestation. This commit lands v0.1.15 (CCH fix + initial discovery wiring) plus v0.1.16 (complete auto-discovery loop) together as a single PR. Bug #1 (v0.1.15) — broken billing header since initial commit: archon-cli's identity.rs::billing_header() built a billing string in the right format but inserted it as a SYSTEM PROMPT TEXT BLOCK (invisible to Anthropic's HTTP-header billing layer) and omitted the cch= field entirely. compute_fingerprint used SHA256 of three cherry-picked characters from the first user message — bears no relation to xxhash64-of-body that Anthropic actually validates. Fix mirrors claurst exactly: - New crates/archon-llm/src/cch.rs: xxhash64(body, 0x6E52736AC806831E) & 0xFFFFF, formatted "cch=<5hex>". - anthropic.rs: spoof mode now adds HTTP header x-anthropic-billing-header: "cc_version=...; cc_entrypoint=...; cch= ; cc_workload=...;" computed from the actual serialized body bytes per request. - identity.rs: deleted compute_fingerprint, deleted billing_header() method, removed the broken billing-as-system-prompt-block insertion. - Cargo.toml: + xxhash-rust = { workspace = true, features = ["xxh64"] } v0.1.15 also wired discover_claude_code_identity() into IdentityProvider construction (it had existed but was only called from tests). Bug #2 (v0.1.16) — discovery infrastructure unfinished: Even after v0.1.15 wired discovery into production, version discovery from binary strings did NOT work on Bun-templated versions like Claude Code v2.1.119+ — the version is templated at runtime, not a literal string. Spoof would fall back to the hardcoded spoof_version="2.1.89" config default (30 patch versions stale). Fix: - identity.rs: new version_from_package_json() — walks bin/claude → ../package.json, extracts the npm version field. Reliable on v2.1.119. - discover_claude_code_identity() falls back to package.json when binary strings yield no version. - discover_claude_code_identity() now memoised via std::sync::OnceLock (was walking 234M binary on every call). - New resolve_spoof_version / resolve_user_agent / resolve_entrypoint helpers, each returning (value, source) tuples for log surfacing. - session.rs: both IdentityMode::Spoof construction sites now use the resolvers and emit info!("Spoof identity resolved", version, version_source, ...) at startup. Tests added (bundled in this PR): - crates/archon-llm/src/cch.rs: 4 unit tests (format, determinism, body-sensitivity, cross-reference vector) - crates/archon-llm/tests/cch_header_sent.rs: spoof mode includes x-anthropic-billing-header; clean mode omits it - crates/archon-llm/tests/cch_matches_body.rs: hash recomputed per request from actual serialized body (mutating after hashing fails) - crates/archon-llm/tests/diagnostic_surfacing.rs: 429 response body surfaces through LlmError into TUI failure line - crates/archon-llm/tests/identity_discovery.rs: extraction from synthetic strings + cch_required signal detection - crates/archon-llm/tests/identity_resolution.rs: 12 tests for priority resolution (discovered > config > fallback) for version, entrypoint, user-agent + memoization invariant Verified end-to-end: - cargo check --workspace --tests -j1 --offline: exit 0 - cargo nextest run --workspace -j1 -- --test-threads=2: ALL PASS - cargo fmt --check: PASS - cargo build --release --bin archon -j1: PASS Pending: real-binary TUI smoke test (Steven runs interactively). Spoof identity log line should emit at startup with the actual installed Claude Code version (v2.1.119, not the hardcoded 2.1.89).
