- cargo +1.85 check passes (default + --all-features), plus wasm
target check and a full +1.85 test --all-features run (136 tests).
The declared MSRV is real, not aspirational.
- the lockfile pins the 1.85-compatible transitive set (jsonschema
0.46.9, idna_adapter 1.2.0, icu crates 2.0.x) — idna_adapter 1.2.2
requires rustc 1.86, icu 2.3 requires 1.88; stable still resolves
and all tests pass.
- review #001 is now fully resolved (status: fully-resolved). A CI
MSRV job can gate on 'cargo +1.85 check' once CI exists.
- signal tests use a marker-file readiness signal: the child's command
is 'echo ready > <marker>; exec sleep 60', the test polls
wait_for_file(marker, 5s) — marker exists = the shell exec'd, so the
signal lands on the real target regardless of machine load. Applied
in tests/pty.rs (both signal tests), tests/pipe.rs (SIGTERM), and
the src/local unit tests; wait_for_file lives in tests/common.
- cancel-cleanup post-action sleeps became bounded polls for the
child's death (kill(pid,0) -> ESRCH, 5s deadline) — faster and
flake-proof in both directions.
- resize/cat-stdin tests need no readiness signal at all: the adapter's
input pump processes chunks in order — the sleeps there were pure
latency (integration suites now ~40ms, was 200-270ms).
- signal_after_child_exit_takes_both_kill_fallbacks: a late signal
(after the child exited) takes kill(-pgid) fail -> kill(pid) fail ->
warn + return, with no panic — the reachable part of the
REQ-TTY-02 fallback chain.
- the remaining bridge error arms are documented-unreachable through
the public path (per the review's disposition), with per-arm
reasoning in the module doc: try_clone_reader (dup failure),
reader read error (EIO -> EOF mapped), take_writer (second-take
only), writer write/flush (externally-closed fd), waiter wait()
(already-reaped child). The ADR-055 §4 -1 sentinel is covered at
the adapter level (exit_error_sends_minus_one) — it also arises
when the oneshot drops on kill-on-cancel.
- local/pty.rs line coverage 80.85% -> 86.01%; total 94.48%.
The channels path no longer carries a second negotiation frame on the
channel's data stream (ADR-009). The open op's registry-validated
input IS the negotiation:
- producer: make_tty_open_handler parses the open op's input into a
NegotiateRequest and drives the new drive_session_pre_negotiated
(same three-pump driver as drive_session, minus the wire-frame
negotiation phase; validate/allocate factored into
validate_and_allocate, shared by both paths). Post-open failures
(unknown backend, allocate_failed, ownership denial) still go to the
client as a 0x00-prefixed negotiation error frame, so the consumer's
M1 disambiguation read applies unchanged. The tty:open scope gate is
enforced by the registry's AccessControl (not re-checked in the
handler).
- consumer: open_via_channels parses params locally (fail-fast before
a channel is allocated), opens the channel, and starts raw-chunk
mode directly (from_halves_raw — no negotiation write; the
0x00-error-frame peek retained).
- tty_open_spec's input schema is now the partial NegotiateRequest
shape (carriage/backend/cmd required; backend params stay free-form
— raw JSON Schema is permissive on unknown keys).
Prerequisites landed upstream: alkcall 0.4.0 enforces
OperationSpec.input_schema at dispatch (the registry check this design
leans on never existed before); alkcall 0.4.1 parks early-arrival
chunks for un-adopted channels instead of dropping them — the open
response / producer's-first-write race was silently losing the first
chunks (found by L3's test; the session never resolved).
L3: open_via_channels + from_bidi_stream_via now covered end-to-end
(5 session tests + pre-negotiated adapter test + shared-harness tests
in the new crate::testing module; the channels harness moved there so
session tests share it).
Verification: cargo test 93 lib (default), 116 lib + 19 integration
(--all-features); clippy -D warnings native + wasm clean; fmt clean;
doc 0 warnings; wasm check clean.
Update the remediation plan with a resolution section and per-finding
status. Nine findings resolved in commit 9944153; L1, L3, L6, N4, N6
remain open.
