* fix(providers): remove the chipotle/pepper provider (#13131)
amelia.chipotle.com (the reverse-engineered Amelia chat-widget backend
chipotle/pepper-1 talked to) now returns 404 on every route, including
root, from its Azure Application Gateway — confirmed live 2026-09-15.
This regressed from a WS handshake timeout (#4037, June 2026) to a
fully decommissioned host, so the upstream protocol cannot be fixed.
Owner decided to retire the provider entirely (Option B), following
the phind/kluster quiet-removal precedent: no REMOVED_PROVIDERS.md
entry (reserved for operator takedowns), just a one-line note under
FREE_TIERS.md "Removed / no free tier".
Removed every surface: executor, registry entry, executors/index.ts
and providers/index.ts wiring, noauth provider catalog entry,
ProviderIcon generic-fallback set, the autoCombo exclusion-list
comment, the chipotle_error code from the sanitizer allowlist,
PROVIDER_REFERENCE.md (regenerated), and every doc/test reference.
Regression test: tests/unit/issue-13131-chipotle-provider-removed.test.ts
asserts the provider is fully gone from the executor registry, the
provider REGISTRY and the noauth catalog, and that the executor module
no longer resolves — not a live-network repro (flaky/third-party).
Several existing tests used "chipotle" only as a generic noAuth-provider
example (proxy scoping, error classification, onboarding, fallback
text) with no chipotle-specific behavior under test; those were
re-pointed at another still-existing noAuth provider
(cloudflare-playground / duckduckgo-web) rather than weakened.
* test(providers): document the agnes-cn/chipotle count coincidence (#13131)
provider-node-reserved-prefix.test.ts's REGISTRY id+alias walk was
already red on the base tip (414 vs. expected 412) from agnes-cn
(#13399, +id/+alias). Removing chipotle's REGISTRY id/alias in this
PR nets it back to 412, making the test pass again without a numeric
edit — record why in a comment so it doesn't read as an untracked
coincidence later.
