glm-5.3-flash 086aeb4135 local: the non-blocking resolver — tokio lookup_host replaces the blocking to_socket_addrs
- resolve_target + local_tcp_dial resolve via tokio::net::lookup_host
  (the blocking std resolver parked the pump on resolver latency —
  the review 003 S-1-adjacent residue); the module doc's blocking
  caveat retired
- semantics unchanged: the dial keeps its try-all-addresses loop, the
  egress keeps first-address (upstream parity)

Verification: cargo test --features local (15 suites green), clippy
--all-targets --all-features -D warnings clean, fmt clean.

glm-5.3-flash 4d9796be64 publish-prep: the v0.1 pre-publish round — the README, the CHANGELOG, the license files, the readme field
- README.md: the alktunnels-shape quick start (producer registration,
  the three consumer sessions, both doors, the producer-side
  listener), the architecture table, the feature matrix, the
  verification commands — self-contained, since docs/architecture/
  rides the package but docs/reviews|research|plans do not
- CHANGELOG.md: the Keep-a-Changelog 0.1.0 entry (the sibling shape:
  Unreleased section + tag links)
- LICENSE-MIT / LICENSE-APACHE: copied from the siblings (crates.io
  license-file convention; the crate license is dual from Cargo.toml)
- Cargo.toml: `readme = "README.md"` (the sibling pattern; the
  packaged crate showed `readme = false`)

Verification: cargo test + cargo test --all-features (15 suites each),
clippy --all-targets --all-features -D warnings, fmt --check, doc
--no-deps (0 warnings), wasm32-unknown-unknown check (default +
composed), publish --dry-run (64 files, 278.3 KiB).

glm-5.3-flash b43cbd24ba review-003 N-8: the worthwhile residue probed — the BIND Domain-reply wire helper + table, the refusal-recode unit pins, the serve() wrappers, the len/is_empty accessors, the bridge later-batch garbage 2026-09-27 10:45:38 +00:00

glm-5.3-flash d51ea8a262 review-003: fix the frontmatter's invalid YAML — the plain-scalar colons broke the parse 2026-09-27 10:21:57 +00:00
glm-5.3-flash 2db05172ef review-003: the assembly-layer full review — F-1/F-2 fixed, the residue dispositioned
- Review 003 written (docs/reviews/003-assembly-layer-implementation-
  review.md): the batch-2 assembly layer post-landing, the review-002
  template — correctness/security/smells/coverage over the five
  batch-2 modules + the batch-2 consumer/producer diff surface.
  Baseline: 375 default / 620 all-features green, clippy/fmt/doc
  clean, both wasm checks clean, publish dry-run completes,
  llvm-cov 93.68% lines / 91.01% functions.

- F-1 (major, fixed): the cred-bearing door swallowed every in-band
  refusal's mapped reply code (the CONNECT/BIND session-open errors
  and the accept-stage Err were bare closes) — a vanilla client got
  no reply where ADR-007 pins a reply-code-shaped refusal. Fixed with
  a write_refusal_reply helper (the door's boundary codec, RFC
  placeholder BND.ADDR) at all three sites, pinned by
  cred_door_in_band_refusal_surfaces_the_reply_code.

- F-2 (major, fixed): UdpFrontDoor::serve_on returned Ok(()) on a
  fatal relay-socket I/O failure against its own doc contract —
  the Io exit now surfaces as Err; the idle/association/session
  exits stay clean.

- Findings recorded, not fixed (the release-polish round's residue):
  D-1 (associate_with_token 0% covered), D-2 (the composed-egress
  failure matrix), D-3 (the io-kind refusal-table arms), S-1 (the
  UDP door's learned client address), N-1..N-8 (doc lines, posture
  notes, coverage residue).

Verification: cargo test (375) + --all-features (620) green,
clippy --all-targets --all-features -D warnings clean, fmt --check
clean, doc --no-deps clean, both wasm checks clean, publish
dry-run completes.

glm-5.3-flash 04c76e3a41 review: the batch-2 gate closed — the assembly layer verified, R-1/R-2 fixed
Review checkpoint closing batch 2 (the assembly layer). The gate
opens: the never-binds posture, seam contracts, door fidelity, the
bind-first graduation, feature-gate hygiene, and POC fidelity all
verify clean; two findings were corrected in the review change.

Findings corrected:

- R-1 (major): the UDP front door's in-band decode created a fresh
  DatagramReader per call and kept only the first frame of a batch —
  POC #2's first-cut bug (reader state must persist across calls;
  batched datagrams were silently dropped, mid-frame EOF was silent).
  Fix: an owning InbandBridge (persistent reader + pending queue +
  fail-loud mid-frame EOF, the AssociateSession shape) threaded
  through the channel->socket pump; pinned by three bridge unit
  tests (which fail against the per-call reader) and an end-to-end
  doubled-echo door-udp test.
- R-2 (convention 2): seven non-test expects -> typed errors —
  DoorBuildError (both door builders' .build() is now Result),
  ProducerDoorBuildError/ProducerDoorError (the bind decision is
  serve's typed error), the composed table invariant as an egress
  error, register_forwarded_serving -> Result (the alkcall
  diagnostic surfaced), TokenClientError (wrap on a spent client).
  New error types re-exported; test call sites updated.
- R-3/R-4 (doc residues): producer.md's local-backend section
  described a channel pipe — the landed ProducerDoor serves
  serve_socks5_over on the accepted socket directly;
  associate_with_token's doc (the TCP door refuses ASSOCIATE, never
  calls it); SessionOwner's doc (the accept uses SyncHalves/
  OwnedWrite).

Verification: cargo test (default) green; cargo test --all-features
green; cargo clippy --all-targets [--all-features] -- -D warnings
clean; cargo fmt --check clean; both wasm checks clean (default +
composed); local-on-wasm fails at mio as designed; cargo doc
--no-deps clean.

Task: tasks/implementation/review-assembly-layer.md (status:
completed; the batch-2 gate opens release polish).

glm-5.3-flash 1addedfdd0 assembly: the cross-cutting integration suite + docs sync (batch 2 closes)
- tests/assembly-integration.rs (7 tests, local + composed): the full
  -D story (vanilla cred-bearing client -> TCP door + UDP door ->
  producer w/ local providers -> real echo targets; CONNECT + BIND +
  ASSOCIATE live, one-command-per-connection, teardown + fresh
  sessions), the composed story (direct_egress + bindfirst_accept +
  real TCP dial; all three commands; the lazy-table dial-count
  witness), mixed assembly (channels-native + door clients on one
  registration; composed seams beside native sessions), the assembly
  teardown matrix (UDP-door idle bound; channel reaped; fresh
  association after), the producer door driving all three commands,
  and the -D domain-target pin (resolution at the producer's seam,
  ADR-012).
- Fix the drift the suite surfaced: ComposedEgress::next_reply ended
  fresh (never-opened-table) associations at birth — the ended-relay
  Err now fires only once a tunnel existed and every relay ended; the
  fresh table parks (the readiness contract). Regression-pinned in
  tests/composed-egress.rs (fresh_association_parks_before_any_
  tunnel_is_opened).
- Harness: the composed-accept machinery single-sourced into
  tests/harness.rs (the composed suites' shapes + the five-gate
  composed identity); composed-accept.rs consumes the shared shapes.
- Docs sync: README Current State (the assembly layer landed; both
  suites named), lib.rs crate docs (the assembly-layer paragraph),
  consumer.md (the TokenClient door-only contract + the
  one-command-per-connection posture reconciled).
- Task assembly-integration-suite: completed; Notes + Summary filled
  (the local-on-wasm failure observed: mio's unsupported-wasm error).

Verification: cargo test (375), cargo test --all-features (615),
clippy --all-targets -D warnings (default + all-features), fmt --check,
doc --no-deps (0 warnings), both wasm checks (default + composed),
local-on-wasm fails as designed.

glm-5.3-flash 4e1673eefc composed: the bind-first accept — the listener on a listen resource
Lands the composed accept (ADR-007 variant 2 / ADR-008): the BIND
accept whose listener lives on an alktunnels 0.2.0 bind-first listen
resource, at the graduation's vanilla fidelity.

- `composed::bindfirst_accept` — the BindAcceptFactory: opens the
  listen channel (reply#1 advertises the open-op reply's real
  `bound`, the 0.8.0 reply projection — no expected-addr stand-in),
  inserts the minted `listen` token into the correlation registry,
  and returns the accept future parked on the token's oneshot.
- `composed::register_forwarded_serving` — the forwarded-op serving
  half on the SOCKS5 producer's connection: the shared handler
  correlates by token and owns the middle pump (either-EOF
  completion; a three-party per-direction shutdown cascade would
  deadlock).
- The Sync-bound wrinkle: `SyncHalves`/`OwnedWrite` (mutex
  Sync-proof, no unsafe) over the forwarded halves; the owner
  (`ForwardedOwner`, the TunnelListener) rides inside the write
  payload — dropping the handle drops the session, halves, and
  listener together (teardown structural, compiler-enforced).
- `tests/composed-accept.rs`: the full story (real bound, real peer,
  raw pass-through round trip), client-gone teardown drop-witness,
  distinct tokens for concurrent BINDs, per-accept isolation of a
  FORBIDDEN forwarded open, late-forwarded correlation miss.
- The producer-side adopted forwarded entry rides the per-adopter
  contract (transport-EOF reap), as upstream's bind-first suites
  concede; the no-leak probe reflects that shape.

Verification: cargo test (default + --all-features), wasm
check/clippy (hard gate), clippy --all-targets --all-features -D
warnings, fmt --check — all clean.

glm-5.3-flash 3128d2bd4f composed: the direct-op egress — the lazy destination→tunnel table
The `composed` feature's ASSOCIATE egress (ADR-008's composed
variant, ADR-009's gate): `composed::direct_egress` — each
destination dials through an alktunnels 0.2.0 direct-op channel
(`TunnelSession::open_direct`, `Substrate::Udp`), per-target ACL
for free, the POC #2 `ComposedEgress` shape ported to the landed
seam types.

- `Cargo.toml` — `composed = ["dep:alktunnels"]` (alktunnels pinned
  "0.2.0"; rides `composed` alone, `cargo tree --edges normal`
  spot-checked); dev-dep for the composed suite.
- `src/composed/mod.rs` — the lazy destination→tunnel table
  (LRU-capped, `DEFAULT_MAX_TUNNELS` = 256), per-tunnel relay tasks
  draining a shared inbound queue, `SessionOwner` (the owner wrapper
  shared with the composed accept — the batch-1 review's
  Sync-bound wrinkle), the readiness contract (real async park;
  ended relays → association-end `Err`, never a hot `Ok(None)`),
  framing-once, domain pass-through unresolved (ADR-012), the
  backpressure bound documented on the constructor.
- Two deliberate deviations from the POC shape, documented in the
  task's Notes: the closed-queue condition is a live-relay count
  (the egress holds its own `Sender`, so the POC's queue-close arm
  was unreachable through this surface); the tunnel codec is
  alktunnels' (`[len]` + payload), not the RFC-framed reader.
- `tests/composed-egress.rs` — round-trips per destination → one
  tunnel each, table reuse, LRU eviction/re-dial, the readiness
  park, the closed-relay-set `Err`, framing-once through the wire
  layer, domain pass-through — over a `wire_tunnel_direct` harness
  topology (the consumer-side shape with the direct op on the
  producer's serving registry).

Verification: `cargo test` + `--all-features` pass (13 suites);
`cargo check --features composed --target wasm32-unknown-unknown`
clean (the hard gate); clippy `--all-targets --all-features
-- -D warnings` clean; `cargo fmt --check` clean; `cargo doc
--no-deps` clean.

glm-5.3-flash 29569d9afd local: the producer-side local backend — the producer's front door
- ProducerDoor (feature local, src/local/producer_door.rs): a real
  TcpListener accept loop handing each accepted connection to the
  landed Socks5Producer::serve_socks5_over — the NoAuth in-stream RFC
  conversation with the local seam providers dialing/egressing/accepting;
  no new protocol-layer code.
- The accept path owns ADR-014's two knobs: the idle-first-byte peek
  (non-consuming) and the max-concurrent-sessions cap (try_acquire —
  an accept beyond the bound is refused door-side).
- ProducerDoorGuard: the listener's lifetime is the caller's — graceful
  close() awaits the loop's end; Drop aborts best-effort (the
  alktunnels TunnelListener teardown posture). In-flight sessions are
  never force-closed.
- Per-connection failures are logged + isolated (the loop continues).
- The BIND gate on this path is the builder's bind_policy (no open-op
  identity here; the pump handler's identity-derived gate does not
  apply) — pinned by the 0x02-refusal test.
- tests/local-backend-producer.rs (9): vanilla CONNECT round-trip on
  real sockets, faithful-RFC BIND (real reply#1/reply#2 addresses),
  UDP ASSOCIATE through the real egress, domain resolution at the
  seam, idle timeout, session cap, failure isolation, bind_policy(false).

Verification: cargo test + --all-features green; clippy clean (default,
all-features, wasm32 targets); cargo fmt --check clean; wasm checks
green (backend is local-gated).

glm-5.3-flash 2413646b6a door: the UDP front door — the RFC codec boundary (ADR-003)
- src/door.rs (feature local): UdpFrontDoor — a sibling of the TCP
  door (one relay UDP socket = one association; no shared accept
  loop). Inbound datagrams decode via parse_udp_request at the door's
  codec boundary and ride in-band as {addr, data} frames; replies
  encode via new_udp_header back to the client's learned source
  address. FRAG != 0 refused (dropped; association healthy). The
  association's lifetime is the channel's — the relay socket closes
  with the pump and the teardown reaps the adopted channel. The
  client idle bound (ADR-014) is constructor config.
- Pump shape: the association's stream is split (one pump owns the
  in-band write half, the other the read half) — a shared-session
  mutex deadlocks (the channel read parks holding it while the socket
  side's send needs it); the pumps join via select!.
- tests/door-udp.rs: the POC #2 test-8 shape end to end (real UDP
  echo target + local::udp_egress + vanilla RFC-header'd datagram),
  the empty-datagram invariant (F-2), FRAG refusal + health, the idle
  bound + fresh-association health.

Verification: cargo test green (default + all-features + local),
clippy -D warnings clean (default, local, wasm32 target), fmt clean,
cargo doc clean.

glm-5.3-flash b8fd75b9f3 door: the TCP front door — NoAuth raw pipe + RFC 1929 cred-bearing + BIND
The consumer's TCP front door (feature `local`, ADR-005/ADR-014): the
ssh `-D` local exposure vanilla clients point at.

- `src/door.rs`: `FrontDoor::builder().credentials(...).bind(...)`
  → `serve`/`serve_on`. The NoAuth door is the literal raw pipe
  (accept → channel BiStream via copy_bidirectional, zero protocol
  translation). The cred-bearing door terminates RFC 1929 locally
  (the forked accept_password_auth shape) and re-originates in-band
  via the token-carrying consumer sessions — the vanilla replies are
  re-encoded at the door (the RFC codec boundary, ADR-003), the
  password never crosses the channel as a SOCKS password. The BIND
  door rides BindSession with reply#1 fidelity (the advertised
  address passes through unchanged). UDP ASSOCIATE at the TCP door
  refuses RFC-faithfully (0x07 — the UDP door's task). The ADR-014
  accept-path defense: the idle-first-byte window (peek-based,
  door-side close) + the max-sessions cap (semaphore) as constructor
  config; per-accept failure isolation (the loop continues).
- The identity mechanism (decided + recorded in the task Notes): the
  per-credential identity rides the open-op `auth_token` payload
  (CF-005 precedence (1)) — the token is the mapped identity's id;
  the producer resolves it through ServingConfig.identity_provider.
  No per-credential ChannelClient.
- `src/consumer.rs`: `TokenClient` (the token-carrying open surface
  over the taken CallConnection + shared manager) and the
  `*_with_token` twins of the three session constructors through the
  open_with_token_and_negotiate prologue (teardown-at-birth
  preserved); `Socks5ChannelSession::reply_addr` (the CONNECT
  reply's BND.ADDR for the door's re-encoding). Existing surfaces
  untouched.
- `tests/door-tcp.rs`: 10 integration tests — the NoAuth raw-pipe
  round-trip (the POC #1 curl shape), good/bad credentials (the
  establisher witness sees the mapped identity, never the password;
  a rejection opens no channel), the never-pipes-raw-post-auth pin,
  the BIND door's vanilla conversation, the idle timeout, the
  session cap, failure isolation, and the native-session/BIND-token
  regression guards. Harness: wire_consumer_side_with_provider (the
  producer's identity provider configurable).

Verification: cargo test (375) + --all-features (423) green; clippy
-D warnings clean (default + all-features); fmt --check clean; wasm
check + wasm clippy green; default graph stays net-free.

glm-5.3-flash f3c371310c tasks: the batch-2 decomposition — the remaining assembly-layer tasks 2026-09-25 11:07:48 +00:00
glm-5.3-flash a867f0cb81 local: the socket-backed seam providers — tcp_dial / udp_egress / bind_accept
The `local` feature's first-party providers (ADR-008's local variants,
ADR-009's gate): the three seams' faithful-RFC assembly-layer
constructors over the landed seam types; the protocol layer never
sees them.

- Cargo.toml: `local = ["tokio/net"]` (no socket2 — the POCs ran
  tokio-only); the default graph stays net/mio/socket2-free
  (cargo tree spot-checked both ways)
- src/local/: `tcp_dial()` (real TcpStream per CONNECT, domain
  resolution at the provider — the ssh -D semantic; the resolved
  address set iterated, faithful SocksDialError mapping,
  NotAllowed never synthesized), `udp_egress()` (one real UdpSocket
  per association bound 127.0.0.1:0 — the explicit bind decision;
  the POC #2 LocalEgress readiness shape: park on readable(),
  try_recv_from, WouldBlock -> spurious Ok(None); inner bytes
  to_be_bytes() + data, framing-once; resolve at the egress),
  `bind_accept(bind_host)` (real TcpListener per BIND session,
  ADR-007 variant 1: requested port honored when non-zero, local_addr
  as reply#1's BND.ADDR, the accept future owning the listener
  end-to-end, peer byte-exact; two-stage failure mapping; the bind
  host is the caller's explicit choice)
- lib.rs: cfg-gated module + re-exports; crate doc updated
- tests: 12 unit (real-socket round-trips, the readiness contract's
  park-then-datagram, the drop-closes-the-listener witness, the
  refusal mappings) + 6 integration (tests/local-providers.rs,
  feature-gated: the three commands end to end through the producer's
  real dispatch path with real targets, connect-refused -> 0x05
  through the producer's reply, the readiness contract re-pinned
  through the datagram stage, client-gone -> the advertised port
  frees)
- task status -> completed (acceptance criteria checked; Notes +

glm-5.3-flash 431920ddef review: the fix-round gate closed — every review-002 finding verified, batch 2 opens
The closing checkpoint (tasks/implementation/review-fix-round-002.md):
each review-002 finding verified closed against the landed tree, the
full verification sweep green, conventions re-swept, and the gate
condition (ADR-014 accepted, no major finding) holds.

Per-finding verification (all nine checklist points):
- C-1: the take-guard verified — a second await_inbound returns the
  spent shape Ok(None), the re-read structurally impossible (the plane
  owns the stream); pinned by the double-read + reply1-twice tests.
  D-1's one-reader decision recorded (option (a), BindReply1 cut).
- C-3 closed: the builder's explicit bind_policy is the substrate-free
  gate; the presence reading is only the backward-compat default; the
  pump handler's identity-derived gate byte-identical.
- D-2 closed: the full builder chain through .register(...) serves all
  three commands end to end (RegisterMode::ProducerBuilder + the
  integration test, identity witness asserted).
- N-1/N-4 coherent: the cut list gone (zero references), keep-notes
  current, the Refused vocabulary honest at all five sites + the
  harness's minimal producer, wire untouched, provenance extended.
- D-3 resolved (declare side): the channel:open_failed ErrorDefinition
  declared, schema pinned drift-free against the typed parse table.
- N-8 re-run: 96.30% regions / 97.28% lines; every named line covered;
  the residual attributed (accept_bi log arm, fork accepted-uncovered,
  test panic-guards) — no new load-bearing gaps.
- N-5/N-6 verified: the shared module compiles into both crates via
  the crate-root mount + extern-crate-self alias; open_and_negotiate
  single-sources the teardown-at-birth prologue.
- C-2 decided: ADR-014 accepted (option 1 — teardown-governed phases),
  the spec lines carry the posture.
- Cross-cutting sweep green: test 375 green (+ all-features, local,
  composed), clippy -D warnings clean, fmt clean, doc clean, both wasm
  checks clean, publish dry-run completes; no unwrap/expect/panic in
  non-test code (mechanically attributed across src/); no local/
  composed code exists (the batch boundary holds).

One gate-round finding, F-1 (minor), fixed in this change: the
review-numbering collision — "review 002 R-1/R-2/R-4" cited the
batch-1 gate review's findings (tasks/implementation/
review-protocol-core.md) under a name that now means the general
review; reworded to "the gate review's R-N" at all six sites
(producer.rs, consumer.rs, egress.rs, the review doc). Review 002
marked resolved; the next general review doc is 003-*.

Verification: cargo test (375 green), --all-features + --features
local/composed green, clippy --all-targets -D warnings clean, fmt
--check clean, doc clean, both wasm checks clean, publish dry-run
completes, llvm-cov 96.30% regions / 97.28% lines attributed.

glm-5.3-flash 07b8a74241 tests: consolidate the duplicated harness shapes (review-002 N-5)
- new tests/common/mod.rs — the single-sourced shapes, compiled into
  the lib test crate (#[cfg(test)] #[path] mod in src/lib.rs +
  extern crate self as alksocks) and the integration suite
  (tests/harness.rs declares it and re-exports under the consumed
  names; the per-test use-harness surface is unchanged)
- single-sourced: the echo dial (plain + witnessing), the refusing
  dial, the queue egress + echo factory (the harness ChanEgress /
  producer QueueEgress mutex-wrapper divergence collapsed), the
  refusing egress, the raw RFC 1928 client trio (generic over the
  stream; harness RawRfcClient delegates), the datagram frame
  codec helpers (three copies to one), the parked accept factory
- deliberately left test-local: HotNoneEgress / PureHotNoneEgress
  (R-1's two shapes), Witness / FailingSendWitness (drop flags),
  core-integration's HotNoneEgress (concurrency-load variant),
  the typed accept-refusal factories
- zero behavior change: same test population (145 lib / 38
  associate / 41 bind / 40 connect / 41 integration / 30 harness /
  37 differential / 3 doc-tests), no tests folded, net -307 lines

glm-5.3-flash 8dbe73d49b tests: the review-002 coverage residue — stage exits, splits, spent arms (N-8)
Eighteen new tests, zero production-code changes; every line the
review attributed in §N-8 is now covered (verified by a
`cargo llvm-cov --show-missing-lines` before/after diff).

- producer: the datagram stage's failure exits pinned as direct unit
  tests on `run_datagram_stage` (the serve layer discards StageExit,
  so the unit shape is the only place the exact matrix is assertable)
  — `ReplyFrameRejected` (a joint-bound-violating reply), `EgressEnded`
  via `next_reply`'s Err, `Io` via a failing write and a failing read;
  the `send`-failure arm got the serve-layer drop-witness treatment
  (full ASSOCIATE conversation, EOF after the refusal, the drop flag
  flips — teardown-at-birth on the failure path)
- producer: the quiet wait's `Err(_)` arm (a read *error* ends the
  wait `Ok(())`, the accept future drops with its owned state — the
  client-gone contract's error-shaped twin; driven directly on
  `bind_quiet_wait_and_serve`) and the BIND reply#2 Domain-peer
  fallback (`TargetAddr::Domain(_, port)` → `0.0.0.0:port`, the data
  plane live end to end)
- producer: the establisher's `None`-witness arm (the registration's
  optional witness seam) added to the existing unit test
- consumer: the two front-door-bridge `split`s tested on live
  `Socks5Stream<BiStream>` streams via `build_skip_auth_bi_stream`
  (two duplexes joined the `open_and_negotiate` shape) — raw framed
  bytes through both halves; the BIND split leaves the take-guard
  untouched (`await_inbound` still reads the reply#2 phase)
- consumer: the single-arm residue — spent `send_datagram`'s `Io` arm
  (+ the spent-`recv` `Ok(None)` shape asserted alongside), the
  mid-batch later-frame `Err` dropping the pending `Ok`s (the
  fail-loud-drops-pending semantics), ASSOCIATE `into_inner`'s `Ok`
  pairing, `BindDataPlane`'s `poll_flush`/`poll_shutdown`
  passthroughs (the BIND door's half-close), `read_reply2`'s
  version pin (a foreign producer's non-5 reply#2), the
  ASSOCIATE/BIND session `Debug` bodies, the spent-`close` no-op
- egress/error: the three seam-handle `Debug` renders
  (TargetHandle / BindTargetHandle / BindAccept) and
  `SocksEstablishmentReason`'s `Display` (each variant renders as
  its canonical wire code)

Coverage: 96.31% regions / 97.22% lines; no new accepted-uncovered
entries (the residual uncovered lines are the pre-existing
out-of-scope set + producer.rs 188-189's untestable `accept_bi`
substrate-failure log arm). One test-only select-shape discovery
recorded in the task Notes: `tokio::select!`'s random branch order
can drop a not-yet-polled accept future before its owned state
exists — the quiet-wait test parks once before erroring so both
branches are guaranteed started.

glm-5.3-flash 986bd13ce7 adr-014: the idle-timeout posture — teardown-governed phases, no protocol-layer idle bound
- ADR-014 accepted (review 002 C-2): the pre-command handshake, the
  BIND quiet wait, and the association lifetime are all
  teardown-governed; the protocol layer never times out (option 1)
- the BIND relationship recorded as same regime (ADR-007 decided one
  phase's ends by designing BIND; ADR-014 records the inherited
  resolution — one principle, not two)
- the doors' accept-path obligations recorded pre-batch-2 (accept-stage
  idle bound, per-credential/per-peer caps, accept-queue bounds);
  revisitable additively (an optional producer-side idle seam would
  be config, not wire)
- spec lines carry the decided posture: wire.md (association-lifetime
  bullet, no-in-band-control bullet, preamble, frontmatter);
  producer.md (the open handler, the local-backend section, decision
  table, frontmatter); overview.md ADR index
- one upstream-fidelity correction: upstream's dial timeout maps to
  0x06 (TTL expired), not 0x01 as the review sketch suggested

- D-3: socks5_open_spec declares the channel:open_failed
  ErrorDefinition (alktty-ported schema, adapted) — reason enum is
  the full ADR-049 §3 five-code vocabulary matching
  SocksEstablishmentReason's parse table; description carries this
  crate's gate classes (FORBIDDEN / INVALID_INPUT /
  channel:too_many_channels) + the no-phantom-channel property.
  Pinned by open_spec_declares_the_open_failed_error_definition,
  which round-trips every enum value through the typed vocabulary —
  schema and typed view cannot drift. Module doc updated from claim
  to fact.
- N-3: DatagramReader::feed's structurally-unreachable let-else
  restructured — the header read folds into the let-else's else arm
  (live-else shape); zero behavior change, wire suite green
  unchanged.
- N-9: is_mid_frame kept; doc names the anticipated batch-2 consumer

glm-5.3-flash 53739b20cb consumer: the BIND reply#2 re-entry guard + session hygiene (review-002 C-1, D-1, N-6, S-2)
- C-1: BindSession::await_inbound is take-guarded — the first read
  takes the session's stream; the returned BindDataPlane owns it (the
  TakenInner pairing posture; the session stays the teardown owner),
  so a second call returns the family's spent shape Ok(None) and can
  never re-read the live data plane. A failed read restores the inner
  (the phase is only consumed on success; the producer ends the
  session on every post-reply#1 failure exit, so a re-call EOFs —
  never a live data-plane re-read either way). Pinned by the
  double-await_inbound integration test (the spent shape + the
  data-plane bytes asserted untouched) and the spent-BIND unit test.
- D-1: one normative reply#2 reader (option a) — the session's
  await_inbound; BindReply1::await_inbound is cut and reply1() is
  documented as a view (bind_addr + raw_mut), matching its actual
  usage; the reply1()-twice re-entry path is closed (pinned by the
  view test).
- N-6: the three session constructors' prologues collapsed into one
  private open_and_negotiate helper (teardown-at-birth in one place);
  zero behavior change.
- S-2: the EOF-propagation doc line on all three reap sites (the
  dropped teardown_channel handle is deliberate — the graceful shape;
  clear_all aborts instead).
- BindDataPlane is un-lifetimed (owns the stream); into_inner returns
  the owned Socks5Stream<BiStream>; docs synced (module + session
  docs, consumer.md §The BIND client).

glm-5.3-flash 6d14d35a54 tasks: decompose the review-002 fix round — eight dependency-ordered tasks
The general review (docs/reviews/002-protocol-core-implementation-review.md)
decomposed into the fix-round group, grouped so no session carries
both a code-fix vertical and the test sweep:

- fix-bind-reply2-reentry: C-1 (the BIND reply#2 re-entry guard) +
  D-1 (the reader decision) + N-6 (the constructor prologue
  helper) + S-2 (the reap doc line) — one consumer session
- fix-producer-gate-policy: C-3 (the explicit BIND gate input) +
  D-2 (the register/builder coverage) + S-1/N-2 (the stage doc
  lines) — one producer session
- fix-rfc1928-posture: N-1 (the keep-or-cut pass) + N-4 (the honest
  refusal vocabulary) — one fork posture session
- fix-hygiene-residue: D-3 (the ErrorDefinition declaration) +
  N-3 (the unreachable let-else) + N-9 (the is_mid_frame note)
- fix-coverage-residue: N-8's attributed line list — tests only,
  after the code fixes (final shapes)
- fix-test-helper-consolidation: N-5 — after the coverage round
- architecture/adr-014-idle-timeout-posture: C-2 — the ADR-sized
  decision, independent, before the doors exist
- review-fix-round-002: the closing checkpoint; the batch-2 gate

glm-5.3-flash d612d7f7f2 review 003: the protocol-core implementation reviewed — correctness/security/smells/coverage
General review of the landed batch-1 protocol core (docs/reviews/
002-protocol-core-implementation-review.md), complementing the
narrow fidelity review: correctness hazards, security posture,
dead surface, and cargo-llvm-cov attribution, cross-checked against
alkcall 0.8.0 and the sibling crates.

Two majors:
- C-1: BindSession::await_inbound (and BindReply1::await_inbound)
  is re-entrant with no spent-marker — a second call re-reads the
  live data plane as reply#2, silently corrupting the pipe. Fix
  sketched: inner.take() (the session's own None-arm posture) +
  tests.
- C-2: no timeout surface on the pre-command RFC handshake or the
  association (bounded memory, unbounded time; the alkcall
  establishment bound covers only the open op). A decision to make
  before batch 2's doors route vanilla clients through the same
  phases; sketched as an ADR-level choice, not a core defect.

Minors: C-3 (the substrate-free can_bind gate conflates
factory-wired with allowed), D-1 (BindReply1::await_inbound is
spec'd, 0% covered, never called — the two-reader ambiguity), D-2
(Socks5Producer::register + the builder's egress/accept setters
unexercised — the spec'd assembly shape has no test), D-3
(error_schemas declared vec![] while params.rs's doc claims the
ADR-049/ADR-016 contract; alktty declares it), S-1 (the stage's
Ok(None) defense is livelock-safe but rate-unbounded — posture
note), N-1 (review 001's keep-or-cut triggers fired:
StandardAuthentication/skip_auth_this_is_not_rfc_compliant/
CheckResult impls are cut candidates; ConnectError/transfer/
wait_on_tcp stay as hand-port-map companions; Bug is now consumed).

Coverage (94.52% regions / 95.55% lines): the load-bearing gaps
attributed in N-8 — the two untested split surfaces, ASSOCIATE
into_inner's Ok arm, the datagram stage's three failure exits
(ReplyFrameRejected/EgressEnded/Io), read_reply2's version arm,
plus single-arm cosmetics.

glm-5.3-flash 16b21e3447 review 002: the protocol core reviewed — readiness-contract hardening + two convention fixes
The batch-1 gate review (tasks/implementation/review-protocol-core.md):
all eight criteria examined (seam contracts, wire fidelity, access
control, teardown/lifecycle, conventions, wasm, POC fidelity, docs
sync); the gate to batch 2 opens. Findings R-1/R-2 were corrected in
the review change; R-3..R-5 are doc residues fixed in the same change;
R-6 is accepted with rationale.

- R-1 (major): the datagram stage's Ok(None) re-park is unsafe against
  a zero-yield egress — a next_reply that is a pure instantly-ready
  Ok(None) with no await wins every select! poll and livelocks the
  stage on a current-thread runtime (empirically reproduced; the
  landed unit test's mutex masked the hazard at its lock's yield
  boundary; multi-thread survives). Fix: the Ok(None) handler yields
  before re-parking; a pinning unit test drives the strictest
  zero-yield violator.
- R-2: the two into_inner expect()s (consumer sessions) become typed
  Result<_, SpentSessionError> — convention 2's no-panic rule; spent-
  session unit tests pin the shape; test call sites updated.
- R-3/R-4/R-5: doc residues — stale task-time phrasings in
  egress.rs/producer.rs, producer.md's register() sketch reconciled
  to the landed signature, the establishment-bound test doc reworded
  to what the substrate-free probe actually pins.
- R-6 (accepted): the wasm gate rides a transitive getrandom/wasm_js
  feature unification (alkcall -> jsonschema/referencing -> ahash) —
  verified compiling clean today; noted for OQ-SK2-06.

Verified: cargo test 348 green; --all-features green; clippy
--all-targets -D warnings clean; fmt --check clean; both wasm checks
clean (from a clean wasm target dir); cargo doc --no-deps clean.
The bind-only-identity reconciliation from the integration session
was independently verified as correct (ADR-006 as landed; the suite
pins it). Batch boundary holds: no local/composed code exists.

glm-5.3-flash 1ad8d9d489 core: the cross-cutting integration suite + docs sync
The batch-1 closing task: nine cross-cutting integration tests
(tests/core-integration.rs) pinning the whole protocol core end to
end over the channels harness, plus the architecture-sync docs pass.

Tests:
- One registration, all three commands: CONNECT + ASSOCIATE + BIND
  interleaved live on the one channels/socks5/sub op; a teardown
  ends only its own session (mux/demux isolation) — the POC #2/#5
  regression guard, complete.
- Concurrency: nine concurrent mixed-command sessions (raw topology)
  and six through the typed consumer sessions (consumer-side
  topology) — the mux/demux pinned in both channel-id allocation
  directions; fresh round-trips after the burst; no channel leaks.
- Teardown matrix (wire.md §Sentinels and lifecycle): CONNECT
  half-close, ASSOCIATE EOF, BIND client-gone (a parked accept so
  the quiet-wait exit is deterministic) — each followed by fresh
  sessions of every command (no connection poisoning).
- Identity/scope matrix (ADR-006 end to end): open-only (CONNECT +
  ASSOCIATE serve, BIND refused 0x02 at the command gate), bind-only
  fail-closed at the open gate for all commands (the spec drift the
  task's phrasing carried, reconciled — ADR-006's open gate requires
  socks5:open unconditionally), both-scopes (everything, granted
  explicitly); the CF-006 witness asserted per row.
- The readiness contract re-pinned under concurrent load: a
  hot-Ok(None) egress across concurrent associations does not starve
  the datagram stage's channel branch.

Docs sync: README Current State ("the protocol core is implemented"
+ the landed inventory; the decomposition residue gone); consumer.md
§Wiring reconciled to the landed session signatures; ADR-006
§Consequences states the grant asymmetry explicitly; lib.rs crate
docs describe the landed surface.

glm-5.3-flash c57451545d consumer: AssociateSession — the framed datagram stage + e2e suite
The UDP ASSOCIATE consumer session (POC #2's shape, consumer.md §The
associate session, ADR-003):

- `AssociateSession::associate` — open → no-auth → ASSOCIATE → reply;
  the sentinel BND.ADDR is received (`relay_addr()`, RFC fidelity)
  and never used for addressing (the handle is the channel). The
  ASSOCIATE DST.ADDR is the vanilla-mirror unspecified address.
- `send_datagram` — frames exactly once via the crate's wire
  `frame()` (the framing-once mirror; the u16 joint bound enforced
  at frame time). Takes `impl ToTargetAddr` (ADR-012 posture); a
  `ToTargetAddr for &TargetAddr` impl was added to the forked codec
  so a `TargetAddr` value survives across sends.
- `recv_datagram` — the incremental `DatagramReader` + batched-
  datagram pending queue, state persisting across calls (the POC's
  reader-state finding); `Ok(None)` on channel EOF; fail-loud on a
  stream end mid-frame and on undecodable frames (`WireError` → the
  forked `AddrError`/`UdpHeaderError` RFC classes — the consumer
  mirror of the producer stage's `UndecodableFrame` exit).
- `shutdown` — the half-close; the mux's implicit-EOF sentinel
  reaches the producer's stage as EOF (association lifetime =
  channel lifetime). `close()`/`Drop` own the teardown (sync reap +
  structural EOF, the CONNECT/BIND posture); teardown-at-birth on
  in-stream refusals; no `Clone` (compile-fail asserted).
- Typed error surface: open failures are `SocksSessionError::Open`
  (ADR-049); the missing-egress 0x07 and factory-failure codes
  surface from `associate` as `Rfc`.

E2E suite (`tests/consumer-associate.rs`, 8 tests over the harness):
round-trips (multiple in-order datagrams, one association, sentinel
relay address asserted), the split-datagram persistence test (a 60
KiB datagram reassembling across the call boundary + the pending-
queue drain — both halves of the persistence invariant), the empty-
payload round-trip (F-2, never EOF), shutdown → a fresh associate
succeeds immediately (the POC's test 4), Drop teardown + connection
health, the missing-egress refusal (typed 0x07, no phantom channel),
the egress-factory failure mapping, and the CONNECT+ASSOCIATE
regression guard (interleaved on one registration). Unit tests (4)
pin the reader internals over a duplex (`skip_auth`'s
handshake-free path).

  no second codec, ADR-011) returning BindDataPlane (into_inner /

- Teardown ownership (the CONNECT session's posture): Drop sync-reap +

- Teardown ownership (alktunnels ADR-005 posture): Drop sync-reaps
  the adopted entry (teardown_channel is sync; Drop cannot await) +
  the pipe drop EOFs the producer pump structurally; close() is the

  refusal tears the channel down in connect (teardown-at-birth —
  no phantom channel); no Clone (compile_fail doctest)

glm-5.3-flash 048493fefa producer: the BIND phase model + the socks5:bind command gate (ADR-006/ADR-007)
The TCP BIND dispatch arm replaces its refusal with the full phase
model (POC #5-validated scope), plus the command gate at dispatch:

- The command gate: TCP BIND requires socks5:bind from the per-call
  opener identity (CF-005/CF-006) — the pump handler resolves it
  from the open-op AuthContext; serve_socks5_over<T> takes the
  resolved can_bind boolean explicitly. A scope-less identity gets
  the RFC-faithful ConnectionNotAllowed (0x02) with no factory call
  (the gate precedes the seam) while CONNECT still serves it.
- The phase model (wire.md §BIND): the BindAcceptFactory at the
  command-read interception point → reply#1 carrying BND.ADDR (the
  factory's bind_addr) → the quiet wait (single-shot select!, exactly
  two exits: the one accept, or the control stream's EOF/garbage/
  error; any byte = protocol garbage → session ends, no data plane;
  the accept future's drop IS the client-gone teardown) → reply#2
  carrying the peer address (via the fork's published new_reply) →
  pump_bidi inline (the CONNECT shape, R-02).
- Two-stage RFC-faithful failure mapping: factory failure → reply#1's
  mapped code; accept-stage failure → reply#2's mapped code, no data
  plane. No phantom listeners, no phantom data planes.
- The no-factory default is the wrapper-aware in-band variant
  (ADR-007 variant 3, documented): sentinel reply#1 + sentinel reply#2
  (0.0.0.0:0), the full phase model preserved — the channel is the
  connection.
- The accept wait lives in the teardown-governed pump phase, never
  under the establishment bound (ADR-007).

Tests: 16 unit tests (raw RFC client over duplex) + 7 harness
integration tests over channels — happy path, the gate (0x02 while
CONNECT serves, both scopes), quiet-wait garbage, client-gone
teardown (owner-flag witness), both failure stages over channels,
no-factory variant 3, and the three-command regression guard (CONNECT
serves, BIND serves under its gate, ASSOCIATE still refuses).

Verification: cargo test green (96 lib + 26 harness + 37
differential); clippy -D warnings clean (all targets, native +

The crate's core task (implementation/core-producer-connect): the
producer half of src/producer.rs per producer.md, adapted to the
crate's seam types and the alkcall 0.8.0 establishment surface.

- The session-gate establisher (`socks5_session_establisher`):
  validates/records the opener identity (the CF-005/CF-006 seam,
  ADR-005) via the optional `identity_witness` probe (the alktunnels
  posture); returns `Establishment::default()` — no plan payload
  (the dial happens post-establishment; POC #1's wire note).
- The pump handler (`make_socks5_pump_handler`): `accept_bi()` →
  the forked typestate over the `BiStream` (`accept_no_auth →
  read_command`) → dispatch. CONNECT: the dial seam (`DialFn`,
  ADR-004) at the command-read interception point; success:
  `reply_success(sentinel)` then `pump_bidi` awaited inline (R-02 —
  the JoinHandle tracks the data-plane lifetime). Refusal:
  `reply_error` with the mapped RFC code — no phantom data plane.
- The ASSOCIATE/BIND arms land as RFC-faithful refusals
  (`CommandNotSupported`) — the pre-vertical posture (ADR-008); the
  dispatch skeleton + registration signature carry the seam
  parameters from day one so the associate/bind tasks swap the arms
  without touching the registration shape.
- `register_socks5_openable`: spec + establisher + pump via
  `register_openable_with_establisher` (`timeout: None` = the 10s
  default), scope-gated `socks5:open`. Missing callbacks = those
  commands refuse RFC-faithfully, never a panic.
- `serve_socks5_over<T>`: the substrate-free protocol entry (the
  POC shape), directly testable without channels; the builder
  (`Socks5Producer::builder()`) is the spec'd assembly shape.
- Tests: 11 in-module (substrate-free duplex-driven — round-trip +
  half-close teardown, refusal mapping per variant, missing-dial
  refusal, ASSOCIATE/BIND arms, dispatch guard, establisher witness,
  builder shape) + 5 harness integration (end-to-end CONNECT echo
  with the identity witness, dial refusal 0x05 with no phantom data
  plane, scope-class refusal 0x02, ASSOCIATE/BIND refusals with
  CONNECT still serving, repeated CONNECTs on one registration).
  The harness retargeted to the real producer (`RegisterMode::
  Producer`); the minimal stand-in is a harness-internal helper.

glm-5.3-flash f8773521b9 harness: the producer/consumer integration test harness over duplex
tests/harness.rs — the producer<->consumer wiring over one
tokio::io::duplex carrying the channels 8-byte chunk format, the
alkcall 0.8.0 establishment surface consumed for the first time by
this crate (register_openable_with_establisher + the call/adopt
dance) — the first-consumption risk retired.

- Identities: consumer (socks5:open) / bind (socks5:bind only) /
  both-scopes (explicit, ADR-006) + TestIdProvider (token path).
- In-process seams, no sockets, no `local`: echo_dial /
  refusing_dial (variant-preserving), echo_egress (readiness
  contract verified — next_reply parks Pending when idle) /
  refusing_egress, echo_accept / refusing_accept_factory /
  refusing_accept (two-stage BIND refusal shapes, mapped through
  to_reply_error()).
- Producer-side registration helper: register_socks5_openable_minimal
  + socks5_session_establisher + RegisterMode — the single place the
  producer wiring lives; the CF-006 identity witness rides it and is
  asserted end-to-end.
- RawRfcClient: the hand-rolled RFC 1928 client helper over any
  AsyncRead + AsyncWrite, round-tripped against a byte-level
  hand-rolled server (success + refusal replies).
- Smoke test: harness up -> producer registered -> consumer open +
  adopt -> raw RFC CONNECT -> echo round-trip through pump_bidi.
  Fail-closed probe: scope-less identity -> FORBIDDEN, no channel
  anywhere (the load-bearing POC #1 set_identity wiring requirement,
  explicit in the install hook and tested).

glm-5.3-flash ac361f7610 seams: the three seam types — dial / egress / accept (ADR-004)
- egress.rs: the I/O-plane inversion point, function-not-trait at the

  returned object)
- dial: TargetHandle (boxed halves, +Sync per the ChannelPlan bound),
  DialFn over the typed TargetAddr (the POCs' JSON stand-in retired),
  SocksDialError with the five-variant RFC-faithful mapping
- egress: Egress (send payload-only; next_reply returns inner bytes;
  the readiness contract — Pending when nothing is ready — documented
  on the trait), EgressFactory, EgressError, the egress_factory
  sync-lift constructor
- accept: BindAccept (the accept future owns its resources end-to-end;
  the quiet wait's drop IS the client-gone teardown), BindTargetHandle
  (ownership structural; the composed keep-alive owner rides inside
  the halves provider-side), BindAcceptFactory, the two-stage error
  pair (factory → reply#1; accept-stage → reply#2)
- no substrate type named anywhere in the module; ownership rides the
  handle structurally (no _ bindings)
- 9 new tests: the four error→reply-code tables (all variants,
  byte-compared), the sync-lift Ok/Err paths, the closure compile
  shapes, the Send/Sync/Unpin assertions; lib.rs re-exports the
  surface

- params: the ADR-001/ADR-006 constants (`channels/socks5/sub`,
  `alk/socks5`, `socks5:open`, `socks5:bind`), `socks5_open_spec()`
  (Sub/External/channel-open marker; trivial empty-object input schema
  with loud `additionalProperties: false`; reply
  `{channel_id: integer, minimum 1}` required; `socks5:open` scope),
  `Socks5Params {}` (deny_unknown_fields — empty stays valid forever),
  the `establishment_reason` helper re-export.
- error: `SocksOpenError` (the ADR-049 §4 typed surface, shaped on
  alktunnels' `TunnelOpenError`), the typed
  `SocksEstablishmentReason` vocabulary (the five reason codes,
  parse/as_str; unknown codes never aliased), `SocksOpenError::reason()`
  as the typed view, and `SocksSessionError` (open vs in-stream `Rfc`
  vs `Io` — a refused target is an RFC reply code through the session
  type, consumer.md §Error surface). `SocksError`/`SocksServerError`/
  `ReplyError` re-exported from the forked core.
- lib.rs re-exports the new public surface (convention 15).
- 9 new tests: spec shape, constants, serde round-trip +
  unknown-field rejection, the reason mapping table, the
  non-establishment classes (`FORBIDDEN`/`INVALID_INPUT`/
  `too_many_channels`), future-reason non-aliasing, the three-plane

glm-5.3-flash d530eae5c4 wire: the ASSOCIATE datagram frame codec — frame + DatagramReader (ADR-003)
- frame(addr, payload): [len: u16 BE][addr + data] over
  TargetAddr::to_be_bytes() + payload; the joint bound enforced at
  frame time (checked_add; 65507 + 255-char domain = 65766 > 65535 →
  Oversize) with addr_encoding_len exposed (7 v4 / 19 v6 / 259 max
  domain) and MAX_INNER_LEN pinned
- DatagramReader: incremental reassembly across chunk boundaries
  (split frames, batched frames, partial headers), infallible,
  returning per-frame Results; the addr sub-layout decoded by hand
  (ATYP-keyed, UTF-8-validated) with typed decode errors —
  BadAtyp / ShortAddress / DomainNotUtf8 / EmptyFrame — so the
  producer stage fails the association loud on protocol garbage
  (udp_undecodable_frame_ends_association, POC #2)
- module docs state the framing-once invariant (the egress speaks
  inner bytes; this layer owns the single length prefix — the
  double-framing bug class POC #2 caught), the F-2 invariant at
  payload level (a zero-length payload is a legal empty datagram,
  never EOF; wire len == 0 is unreachable garbage), and the EOF
  layering (the channels-level sentinel, outside the codec)
- doc-sync: wire.md + bast.md residue corrected — "len == 0 is a
  legal empty datagram" replaced with the payload-level F-2
  statement (len == 0 unreachable since addr >= 7 bytes)
- lib.rs re-exports frame, DatagramReader, addr_encoding_len,

- lib.rs: the six skeleton modules per overview.md §Module Map

glm-5.3-flash a2483e4a84 tasks: decompose the protocol-core group — thirteen dependency-ordered tasks
Batch 1 of the Phase 1 decomposition: the default, wasm-clean crate
(producer + consumer + wire + seams + params/errors), per the
architecture spec set (ADRs 001-013) and the three POCs' validated
shapes. The assembly layer (local/composed providers, front doors) is
batch 2, decomposed after review-protocol-core opens.

- foundation: crate-deps (alkcall 0.8.0 first consumption), wire-codec
  (the ASSOCIATE frame + the joint bound), seam-types (the three
  ADR-004 seams), params-errors (the one-way-door surface)
- harness: duplex transport + identities + in-process seams (the
  alkcall 0.8.0 establishment surface proven before the producer)
- verticals: producer/consumer splits per command (CONNECT,
  ASSOCIATE, BIND) — each POC's scope, producer tasks test via the
  raw RFC client, consumer tasks e2e through the harness
- closing: integration suite (three-command regression, teardown
  matrix, identity matrix, docs sync) + review-protocol-core (the
  batch gate)

taskgraph: 8 generations, no cycles, risk path 2.55 (no high-risk
tasks). Also records the wire.md/bast.md len=0 residue (payload-level
F-2 is the operative invariant) as a doc-sync deliverable of the
wire-codec task.

glm-5.3-flash 7bd5d6a7e7 review 001 remediation: the forked core's findings resolved
Batch 1 (F-1 + N-1 + S-2 + N-4):
- reply_success/reply_error write replies with write_all (partial-write
  hazard closed; the err_when-chaining idiom suppresses
  clippy::unused_io_amount — reproduced fresh via a five-variant probe)
- rfc1928.md's write_all bullet records both conversions and the real
  rule (replies are single-shot, all-or-nothing) + the lint blind spot
- reject's doc names the 0xff vocabulary choice (RFC 1929 needs only
  non-0x00); Addr::Domain's deliberating comment pinned

Batch 2 (coverage: L-1 + L-2 + L-3 + S-1):
- client v6 request encoding pinned (22 bytes, ATYP=4, slice bounds)
- Socks5Stream::shutdown() EOF/BrokenPipe propagation pinned
- wait_on_tcp's io-error arm + SocksServerError::to_reply_error's full
  mapping table + read_command's command-phase version mismatch covered
- S-1: read_address's 1-byte-field bound documented; decode-side
  255/256 boundary pinned both faces

Batch 3 (posture notes: C-1, C-2, N-2, N-3 — decided keep-with-note):
- ConnectError: hand-port map's companion (cut if the producer layer
  lands without consuming it); StandardAuthentication: ADR-005
  auth-split is the anticipated consumer; CheckResult same shape
- tracing: the fork's declared logging seam, noted in Cargo.toml

Coverage 92.63% → 93.09% regions / 95.40% → 96.07% lines; the named

Security + code-smell + coverage review of the targeted fork as owned

Findings: 1 major (F-1: reply_success/reply_error write replies with

unused_io_amount under the err_when-chaining idiom, executable-probe
verified; rfc1928.md's write_all rationale is false for these sites),

glm-5.3-flash f8c34444fb rfc1928: the targeted fork — rename + convention pass (ADR-013)
The mechanical half of the posture change: src/vendor/ ->
src/rfc1928/ (module alksocks::rfc1928), tests/vendor-differential.rs
-> tests/rfc1928-differential.rs (git mv — history preserved).

- Fork point pinned: the tree as of 5b18d4d (the extraction review's
  gate commit); provenance permanent in the module docs and the
  extended LICENSE notice (upstream MIT preserved, fork-point +
  post-fork modification statement added — extend, never replace)
- The lint-allow posture dissolved: all module-level #[allow]s
  removed and the suppressed smells fixed (u8::max_value() ->
  u8::MAX, needless lifetimes elided, match_like_matches_macro
  applied, io::Error::new(Other) -> io::Error::other, the
  AuthMethod::new self-taking signature renamed
  into_starting_state, the F-4 ToSocketAddrs string re-worded — it
  no longer names the cut resolve_dns(), the unused ready! macro
  and dead AuthenticationMethod::from_u8 removed, the upstream
  commented-out async-std note folded into the impl doc)
- Module docs rewritten: ownership statement (project conventions
  apply unconditionally), extraction provenance (ADR-011) +
  ownership (ADR-013) + maintenance posture (behavioral reference,
  hand-port path)
- Differential suite survives the rename untouched (32 tests pin
  bytes, not upstream text)

glm-5.3-flash 001aac1fd5 docs: the targeted fork — ADR-013, the RFC 1928 core is owned
ADR-013 supersedes ADR-011's maintenance posture (not its mechanics):
the extracted T-generic subset is fully owned code, the vendor
framing is retired. Module renamed src/vendor/ -> src/rfc1928/
(naming decided in the ADR: 'vendor' names an ownership relation
now gone; 'socks5' would stutter and collide with the future
producer/consumer layers). Fork point = the tree as of the
extraction-review commit (5b18d4d); provenance stays permanent
(module docs + the extended LICENSE notice).

- ADR-013: fork posture, license mechanics (notice extended, not
  replaced; post-fork modifications under the crate license),
  hand-port replaces re-vendor, lint-allow posture dissolved
- ADR-011 marked Superseded (extraction mechanics remain
  authoritative); ADR-002 references re-pointed
- vendor.md -> rfc1928.md rewritten as the owned-core spec (the cut
  table re-read as the hand-port map)
- spec sweep: README index (ADR-013 row, doc table, principle 8),
  overview (module map, deps, ADR table), producer/consumer/wire/
  bast reference vocabulary, open-questions OQ-SK-04 resolution,
  AGENTS.md conventions 4/17 + verification note + context bullet,
  Cargo.toml description

glm-5.3-flash 5b18d4d292 review: vendor extraction — gate opens; F-1 panic arm fixed
The extraction review against vendor.md's cut table, ADR-011
§Amendment, and AGENTS.md conventions. All five file diffs vs the
fast-socks5 v1.0.0 reference checkout read hunk-by-hunk and
categorized (cut / carried changes / adjustments / provenance /
tests); wasm, clippy, fmt, doc all green; RFC 1928 spot-checks
(reply form, method order, UDP zero fallback, domain cap, FRAG
split) independently verified against the RFC text.

F-1 (critical, resolved here): ReplyError::from_u8 kept upstream's
unreachable!("ReplyError code unsupported.") arm while being
wire-reachable — Socks5Stream::read_request_reply feeds the raw
reply byte from the wire into it, and RFC 1928 §6 marks 0x09-0xFF
unassigned, so a misbehaving peer would panic the consumer task.
Unassigned codes now map to GeneralFailure (the RFC's catch-all),
pinned by a new test, and the panic-translation adjustment is
recorded in vendor.md's adjustment list (with the Config-Default
and write_all notes) in the same change.

Findings F-2..F-4 (dead commented code dropped with its region;
Cargo.toml feature-layout comments; the preserved resolve_dns error
string) reviewed and accepted. Review task file carries the full
record; the gate to the downstream task groups is open.

tests/vendor-differential.rs pins the vendored extraction's RFC edge
behavior as explicit bytes, per vendor.md §Maintenance Posture (the
differential-testing contract; ADR-011):

- negotiation: empty/zero method lists -> 0xff, server-order method
  preference, 0x04 greeting refusal before the methods byte, EOF
  mid-handshake typed error, password sub-protocol EmptyUsername/
  EmptyPassword + the 0x01/0xff-then-error reject path
- command reads: unknown command -> 0x07 reply, RSV != 0 tolerance
  (upstream reads it unchecked), ATYP 0x02/0x05 -> 0x08, the
  255-byte domain wire maximum, truncated v4/domain address errors
- reply forms (new_reply regression guard): 10/22-byte shapes,
  constant VER/RSV across codes, zero-addr error replies, caller
  sock_addr verbatim on success
- client session: per-code ReplyError mapping (incl. the 0x06
  double map), domain request encoding, UDP-ASSOCIATE zero-target
  fallback form, skip_auth emits no greeting
- UDP codec: GarbageInReserved, FRAG passthrough (the parser
  returns it; refusing is the caller's job), v6 round-trip,
  payload split
- transfer/wait_on_tcp: pump both directions to completion, EOF on
  clean close, UnexpectedUdpControlGarbage carries the byte

Every non-obvious expectation names the upstream behavior it pins

Extract the T-generic client session from fast-socks5 v1.0.0's

greeting, method-choice read, password sub-handshake, request
encoder, reply reader, socket accessors), the AsyncRead/AsyncWrite
impls, and the pruned Config (skip_auth only).

- typed MissingTargetAddr variant replaces upstream's
  anyhow::Error::msg(...).into() at client.rs:285 (the one SocksError
  addition; the client.rs:528 Other(anyhow!) site went with the cut
  Socks5Datagram)
- use_password_auth's unreachable!() is an error return (upstream's
  None-arm message; convention 2), and the sub-negotiation reply's
  version byte is now checked (was only a dropped debug!)
- write -> write_all in request_header (clippy unused_io_amount;
  byte-identical on a healthy stream)
- cut (not copied): Socks5Datagram, the Socks5Stream<TcpStream>
  convenience impl (connect*/connect_raw), Config::connect_timeout
- 14 first-party duplex tests vs raw-byte mock servers (uncorrelated
  from the vendored server typestate): both handshakes, 0xff
  refusal, version mismatch, domain/IP request forms, the full
  failure-code table, UDP-ASSOCIATE zero fallback, skip_auth,
  io-impl copy, socket accessors

  10-byte / v6 22-byte forms + the reply-code table)
- extraction adjustments: log calls dropped (unused bindings
  renamed), reply_error's parse().unwrap() replaced with a
