wave-2 gate; install + park-drain are one atomic section so a
demux-routed chunk can no longer overtake earlier-parked early

- Zero source changes: the 0.10.0 breaking surface (the loud

wire.md's mirrored sentence corrected
Verified: cargo doc --no-deps clean; cargo fmt --check
- BindFirstPlan gains substrate: Substrate, stamped at establisher
time from the one successful TunnelParams parse (one parse, one
source of truth; the plan-payload change is pre-consumer)
- make_bindfirst_accept_handler drops the second params re-parse and
the silent unwrap_or(Substrate::Tcp) fallback entirely — the
dispatcher reads plan.substrate; no fallback branch remains, so a
future drift cannot silently stamp Tcp into a UDP listen tunnel's
forwarded opens (the raw-vs-framed data-plane mismatch class)
- tests: forwarded_opens_carry_plan_stamped_substrate pins the plan
as the substrate's source over a real UDP bind-first wire flow
(a substrate-recording forwarded stub observes substrate: udp);
the unit downcast + establisher-flow tests pin the stamp
- docs: producer.md (the plan carries {listener, token, substrate};
the forwarded open's substrate also comes from the plan),
ADR-008 §1 (the stamp + the removed fallback)
- task review-002-m1-substrate-fallback: completed (Notes filled)
Verification: cargo test (145 pass), cargo test --all-features (153),
clippy --all-targets -D warnings (default + all-features), fmt

Verification pass against the landed alkcall 0.8.0 surface surfaced one
design gap: ADR-008 §3 pinned the forwarded op's correlation key as the
listen channel's ID, but (1) the serving-side OpenHandler/establisher
surface never exposes the allocated channel ID, and (2) the in-tree
generic ChannelRelay forwards open-op params untouched (it rewrites
only the reply's channel_id), so a spoke's forwarded open would carry
an id the end opener never allocated. Amended (wire still unconsumed —
alksocks is docs-only — so pre-consumer and legal):
- ADR-008 Amendment 1: the bind-first establisher mints a fresh u32
correlation token per open — carried in the plan (for the accept
dispatcher) and contributed as the additive `listen` reply field
(the same projection carrier `bound` rides); the forwarded op's
params rename `channel` -> `listen` with token semantics. Tokens
ride reply fields + params through hubs untouched (relay-transparent
by construction, alkcall ADR-051). Consumer-minted tokens and a new
upstream handler surface were considered and rejected (rationale in
the amendment).
- Spec docs synced: wire.md (the `bound`+`listen` reply section, the
forwarded params), producer.md (bind-first shape + forwarded op),
consumer.md (TunnelListener gains `listen()`; correlation registry
posture), overview.md, OQ ledger (OQ-TN-16 updated),
tunnels-graduation.md.
Task decomposition (tasks/tunnels/, Phase 2 of the graduation — the
alkcall prerequisites are gone):
- direct-op — params/spec/establisher/open_direct (ADR-007)
- bindfirst-params — forwarded-op spec, TunnelListenReply, the
BindFirstPlan + token mint (wire types first, the params.md
ordering precedent)
- bindfirst-producer — bind-first establisher, accept dispatcher,
register_tunnel_bindfirst_openable
- forwarded-receipt — the opener-side serving op + reply-field reader
- tunnel-listener — the listen-flow consumer session (ADR-008 §4)
- local-bind-halves — the `local` TCP bind + accept-pairs loop,
unix parity decision, direct-op DialFn reuse pin
Dependency order: direct-op and bindfirst-params are independent
roots; bindfirst-producer -> {bindfirst-params}; forwarded-receipt ->
bindfirst-params; tunnel-listener -> {bindfirst-params,
forwarded-receipt}; local-bind-halves -> bindfirst-producer.
Verification: cargo test 71 passed; clippy --all-targets -D warnings;
fmt --check; wasm32-unknown-unknown check + clippy clean (docs + task
files only — no code change).
The alksocks graduation research (tunnels-graduation.md) is decided;
the ADRs are normative now:
- ADR-007: the direct open op — channels/tunnel/direct on the one
alk/tunnel ALPN, params {substrate, target} (self-describing JSON
target; ATYP bytes rejected as not schema-describable), scope
tunnel:direct (never implied by tunnel:open), dial-only.
- ADR-008: listen metadata — bind-first listen establisher (reply
gains additive 'bound' = BND.ADDR fidelity; the BIND deadlock +
10s-bound findings dissolve) + the forwarded op
channels/tunnel/forwarded (accept-as-open, params carry
{channel, substrate, peer} = reply#2 fidelity). Accept-first stays.
- ADR-001/002/006 amendments: params layout is per-op; flavor-form
op ids on the one ALPN; per-flavor scopes + the hub re-produce
policy sentence (the hub's ACL governs the final dial).
- wire/producer/consumer/overview/README updated for the new ops,
the three establisher shapes, TunnelListener, open_direct.
- OQ-TN-15/16 promoted + resolved; upstream alkcall asks filed at
alkcall/docs/reviews/008-tunnels-graduation-upstream-review.md
(flavor-form discovery derivation; the establisher → reply
projection).
Verification: cargo test (22 passed), clippy -D warnings, fmt --check
(docs-only change; wasm check unaffected)
Review 001 N-3 (tasks/tunnels/decide-take-framed-halves), decided
before the first external consumer:
- Option 1 (keep as-is, docs carry it), recorded as ADR-005
§Amendment. No external consumer exists (window open — the breaking
reshape was available but undemonstrated); one take_halves semantic
across substrates beats per-substrate divergence; pump_against
composes the framed adapter (UdpHalf), not framed halves; and the
take_framed_halves convenience is additive — it can land after the
first consumer defines its shape.
- consumer.md's datagram section states the posture; review 001 §N-3
resolution note landed; task marked completed.
Docs-only (no code change). Verified: fmt --check, doc --no-deps
warning-free, 63 default / 76 local tests green.
Review 001 remediation (tasks/tunnels/fix-udp-framed-adapter):
- U-1 [major]: UdpHalf now composes the ADR-003 codec at the
substrate boundary — poll_write de-frames channel bytes (incremental
DatagramReader) and sends each payload as one raw datagram;
poll_read frames raw target datagrams and hands frame bytes to the
pump. Targets see payload-only bytes; empty datagrams round-trip
(the F-2 fix end-to-end); >8 KiB datagrams arrive as ONE datagram.
Mechanics the verification gates forced beyond the sketch:
poll_write accepts all offered bytes (tokio copy re-offers a full
window unsatisfied — partial-frame holds deadlock >8 KiB frames),
backpressure is an accepted-byte high-water mark, socket drain
pumps on write/flush/shutdown; >caller-buffer frames stage across
reads (the truncation probe's assertion surface updated per the
re-validation correction).
- U-2 [minor]: connect_udp resolves the target and binds the
unspecified address of the matching family (v6 targets dial from
[::]:0); bind_tcp gains the wildcard-exposure doc warning.
- U-3 [minor]: the 65535 recv scratch allocates lazily on first recv
(full-size read kept — try_recv truncates silently; the MTU-shrink
idea confirmed unsafe in re-validation).
- N-1: the module/connect_udp/UdpHalf docs now describe the composed
codec truthfully.
Gates (permanent tests in tests/local_halves.rs): recording-target
suite (payload-only at the target, empty-datagram round-trip, 9000-
byte single datagram, unframed-target resolution), the 65507-byte
max-datagram staging probe, and the v6 dial gate.
Docs: ADR-003 §Amendment (the boundary mechanics), wire.md truncation
bullet, consumer.md adopt sketch (substrate param). Review 001
resolution notes on U-1/U-2/U-3/N-1; task marked completed.
Verified: 63 default / 76 local tests ×3 repeat runs; clippy
-D warnings (all-targets + wasm32), fmt --check, doc --no-deps
(warning-free), wasm check, publish dry-run.
Split the last open substrate-placement question:
- Unix: ships with the local feature v1 (dial_unix — same halves
shape as TCP; the wire enum already carried unix per ADR-001;
the params task's schema list includes all three values)
- Stdio: OUT of scope — a spawned process's stdin/stdout/stderr IS
alktty's pipe mode (LocalTtyBackend + tokio::process + Stdio::piped,
alktty tty-local.md): three multiplexed logical streams + the
exit-code control chunk (alktty ADR-004) + signal forwarding
(REQ-TTY-02). A stdio bridge here would be alktty's runner mode
with the terminal stripped out — a strictly worse duplicate that
also drops the semantics that matter (a byte tunnel has neither
exit codes nor signals). Remote command execution composes via
alktty on the same channels substrate.
Updated: open-questions.md OQ-TN-14 (resolved), overview.md feature
gate + deps + OQ summary, producer.md OQ ref, OQ-TN-10 promotion
(#3 split), phase-0-findings + both POC summaries' resolution notes,
params task (schema enum includes unix), local-socket-halves task
(unix ships, stdio does NOT — with the composition rationale),
oq-tn-14-tracker task repurposed (boundary-maintenance: re-opens only
if a consumer needs stdio-without-process-semantics — which would
need its own ADR, or if the alktty/alktunnels boundary needs
sharpening).
Verified: taskgraph valid (12 tasks, no cycles)
The Phase 0 OQ ledger (OQ-TN-01..10) promoted into
docs/architecture/open-questions.md (now OQ-TN-01..14, with four
new Phase 1 residues). Six ADRs and four spec docs, all Draft, all
decision-shaped per the SDD process (ADRs carry the WHY; specs carry
the WHAT and reference by number):
ADRs:
- 001 open-params-layout: params = {resource, substrate} — the
producer's stable name, not an address; wire-stable from the first
consumer; unknown substrates fail loudly at schema time
- 002 alpn-strategy: single alk/tunnel ALPN (option A); substrate in
params selects the framing; prior art (SSH/SOCKS5/udpgw) gives no
reason for the split
- 003 codec-and-udp-framing: raw pass-through (stream) / mandatory
[len: u16 BE] (UDP) — F-2 mandate recorded (the codec is mandatory
for correctness, not cosmetics); len=0 = legal empty datagram;
OQ-TN-13 resolved fail-loud (truncation)
- 004 no-backend-trait: halves functions at the assembly layer;
listen is an establisher shape; hub re-produce deferred(OQ-TN-12);
trait re-evaluated at the alknet ADR-078 convergence threshold
- 005 consumer-session-owns-teardown: TunnelSession with
open/adopt/stream_halves/take_halves/pump_against/close/join/Drop —
the W3 adopter gap closes structurally; Drop is the best-effort
fallback
- 006 access-control-posture: the open gate is the boundary;
TUNNEL_OPEN_SCOPE = tunnel:open (stable once published); op-level
ACL; ownership seam; no allowlists in v1; identity = 0.7.0's
precedence chain
Spec docs:
- overview.md: purpose, resource model, deps (alkcall 0.7.0,
wasm-clean default, local feature), module map
- wire.md: the open op (params/reply/typed errors), the data plane
by substrate, sentinels + half-close, byte diagrams
- producer.md: spec, establisher (dial + listen shapes), pump
handler (pump_bidi inline, R-02), registration API, ACL posture
- consumer.md: TunnelSession (forward open + reverse adopt
construction), data plane, teardown API (close/join/Drop incl.
pump-less join semantics)
- bast.md: the BAST doc for the UDP codec (convention 12's trigger
fired — the framing IS binary beyond pass-through)
- open-questions.md: OQ-TN-01..14; 01..10 promoted (faithful to the
phase-0 ledger's final states), 11 partially resolved (collision
domain = per-producer registry per ADR-001; lifecycle open),
12 deferred(scope), 13 resolved fail-loud (ADR-003), 14 open
Verified by an architecture-reviewer pass (2 criticals, 6 majors,
10 minors — all fixed: ADR-001/003-vs-OQ decision-state contradictions
resolved; the Layer-2 mislabel corrected to the ADR-047 §4 per-session
fork; alktty/alknet ADR misattributions fixed; codec placement pinned
to the establisher (pump stays substrate-agnostic); reverse-path
construction named (TunnelSession::adopt + pump_against); security
posture promoted to ADR-006; BAST doc written; F-2 rationale deduped;
README tables completed; channel_id > 0; MTU wording fixed; ADR-047 §5
attributions corrected; impacts lines added to unresolved OQs; review/
ledger pointer paths added to README references).
