# FAILPROOFAI_BINARY_OVERRIDE at user scope; project-scope fallback swaps the

# Gateway default model, used by every CLI without a pin of its own. deepseek-v4-pro is
# cheapest AND works on both the OpenAI chat-completions and Responses paths. Three CLIs
# are pinned away from it below (claude, pi, codex) — each for a payload deepseek refuses.
# EXCEPTION 1: the claude CLI speaks Anthropic tool-use, which deepseek-via-/v1/messages
# doesn't emit correctly (all probes go INCONCLUSIVE), so claude pins to the cheapest
# Anthropic model via CANARY_CLAUDE_MODEL.

: "${CANARY_PI_MODEL:=claude-haiku-4-5}"
# EXCEPTION 3: codex ≥0.145.0 hits the SAME rejection. For a model it has no metadata for
# (deepseek logs "Model metadata not found. Defaulting to fallback metadata") it now sends
# `reasoning:{summary:"auto"}` + `include:["reasoning.encrypted_content"]`, where 0.144.6
# sent `reasoning:null` + `include:[]`. The gateway answers 400 "Encrypted content is not
# supported with this model" (param: include), codex exits before its first tool call, and
# BOTH probes report INCONCLUSIVE — enforcement is fine, there is just nothing to observe.
# No config override strips it (`model_reasoning_summary=none`,
# `model_supports_reasoning_summaries=false`, `model_reasoning_effort=none` all still emit
# `include`), and the old escape hatch is gone — `wire_api="chat"` is rejected outright in
# 0.145.0 (openai/codex#7782). So codex needs a model that accepts encrypted reasoning
# content. gpt-5.1-codex-mini is the cheapest that does AND supports codex's full toolset:
# gpt-5.4-nano accepts the reasoning params but 400s on `tool_search`.
# Do NOT "fix" this by pinning codex to a Claude model the way pi and claude are: the
# gateway routes Anthropic weighted 1:1 through Bedrock, which 400s on codex's request
# metadata (#576). That fails on roughly half of requests — a coin-flip red is worse in a
# daily canary than a consistent one, and a single green probe does not disprove it.

# ── Daemon mode (CANARY_DAEMON=1) ────────────────────────────────────────────
# Probes the configuration users get after `failproofai config`: hooks route
# CLI → failproofaid (Rust supervisor) → warm bun worker over Unix sockets,
# fail-CLOSED when the daemon is unreachable. The binary is cross-compiled on
# the host by ci-entrypoint.sh (rust:1-bookworm, so its glibc matches this
# sandbox) and bind-mounted at /opt/failproofaid/failproofaid by run.sh.
#
# CANARY_DAEMON_DEAD=1 is the fail-closed probe: configure the machine for the
# daemon exactly as CANARY_DAEMON=1 does, then never start it. On a
# daemon-configured machine an unreachable daemon must DENY every hook event;
# if the benign probe command runs anyway, the machine believed it was
# fail-closed and was not. (Live-verified 2026-08-07 against 10 real CLIs: all
# denied — and factory/antigravity retry-stormed the deny for 10 minutes, an
# availability finding this leg exists to keep visible.)
#
# The daemon is started PER PROBE, not once per CLI. The worker inherits the
# DAEMON's environment — the wire protocol carries only {hookEvent, cli,
# stdin, cwd}, never the hook process's env — so FAILPROOFAI_HOOK_LOG_FILE
# only reaches the oracle if the daemon itself is (re)started pointing at that
# probe's log dir. Sharing one log dir across both probes instead would let
# probe A's incidental denies (an agent exploring with reads trips
# block-read-outside-cwd) satisfy probe B's grep — a false PASS.

# These patterns MUST stay machine-shaped. `$1` is the agent's whole transcript, so a bare

# inversion this function exists to prevent. Hence: the structured `"code": 400` form
# rather than a loose `400`, and `not supported with` (the gateway's own phrasing:
# "not supported with this model") rather than `not supported`. Both live failures we have
# seen carry `invalid_request_error` AND `BadRequestError` anyway, so the tight forms lose
# nothing. __tests__/integration-suite/is-error.test.ts holds the fixtures both ways.

# Same ordering rule as probe A: the sentinel leaking into the transcript proves
# the read happened, which outranks our own log claiming we denied it.
#
# TWO exceptions, and only two. If the leak arrived while the agent was being
# denied by canary-read-shell (it reached for the SHELL) or by canary-guard (it
# reached for some OTHER tool), it got the bytes by a route probe B is not
# asking about, and the honest verdict is "unproven" rather than "broken" —
# antigravity failed here for days doing exactly that, with every deny correctly
# issued and honoured (69 hook events, canary-bash + canary-read + canary-guard
# all denying, scored red). The two are one fact wearing two policy names: the
# agent was denied on the tool probe B targets and went looking elsewhere.
# Accepting only the shell half reported the other half as broken enforcement.
#
# Still deliberately narrow: a leak with NEITHER is a FAIL, because that is what
# a CLI ignoring our deny looks like (copilot 1.0.70), and blurring the two
# would blind this suite to the silent-allow it exists to catch. A CLI that
# ignores the deny on the READ tool cannot reach either exception — the probe's
# own payload is exempt from canary-guard by name.
#
# DRIFT IS CHECKED FIRST, and the order is load-bearing. Normalization drift
# denies under `canary-guard` too — same policy, opposite meaning — so leaving
# it below the leak branch would let the widened exception downgrade the very
# silent-allow class (copilot 1.0.70's) this guard exists to catch, from FAIL to
