- percent-encode path-parameter values with a WHATWG path-segment
superset (/, %, ?, #, \\, controls): traversal values, query/fragment
structure, and later-placeholder strings can no longer alter the
request line (FWD-01)
- single-pass template rendering; rendered values are never
re-substituted; unbound or unterminated placeholders error loudly
- append the request path to the base URL directory (https://host/v1
+ /chat/completions keeps /v1) instead of Url::join semantics,
with a post-assembly origin-equality check (FWD-02)
- base_url validation: https/http-only scheme allowlist, explicit
host required, userinfo rejected (credentials flow via
Capabilities only); request_path is never empty
Verification: cargo test (238 lib tests incl. 8 new FWD-01/02 tests),
cargo clippy --all-targets -- -D warnings, cargo fmt --check
- GW-01: /publish validates every NDJSON chunk against the op's
publish_schema (incl. the first-line chunk) via NdjsonChunkStream —
terminal Err(INVALID_INPUT)/422 on violation, matching the wire
dispatcher's per-chunk contract. Route-level fix; the alkcall spine
was explored and rejected (wire validation is pump-side by design).
- GW-06: the body is streamed, not buffered — Body::into_data_stream()
-> newline-framed BufferedLines -> lazily parsed chunk stream.
ADR-068 documents the streamed semantics and the 2 MiB per-line cap.
- GW-08: /batch capped at 100 operations (INVALID_INPUT 400).
- GW-09: internal-op batch entries now carry generated UUID request ids.
- GW-10: first publish line missing `chunk` is rejected INVALID_INPUT.
- GW-11: redundant /publish pre-checks removed; enforcement rides on
invoke_sink via the shared dispatch spine.
- HY-13: the vacuous stub test was replaced by a body-cut-short test.
- Adjacent: INVALID_OPERATION_TYPE now maps 422 (with identity) / 401
(without) in error.rs — the route relies on the shared mapper since
the pre-checks are gone (GW-03's finding; was a 500 fall-through).
Verification: cargo test 211 passed; cargo clippy --all-targets -- -D
warnings clean; cargo fmt --check clean.
