deepseek-v4-pro dd232c3d47 fix(typedef): fix code examples and cross-doc inconsistencies from second review
- Fix code examples hardcoding little-endian: read_string, write_string,
  read_string_indirect now take endian parameter and use match on Endian.
- Fix TUnion dispatch examples: remove undefined functions (read_u8,
  read_field, read_struct, read_f32_raw), remove Value returns
  (contradicts 'no intermediate Value tree'), add endian-aware
  discriminator reading for Uint8/Uint16/Uint32.
- Fix read_f32 example: inline the endian-aware conversion instead of
  calling undefined read_f32_raw; document it as aligned-mode only.
- Fix architecture README: 16→17 kinds in schema-layer and validation
  descriptions.
- Fix ADR-095: clarify validation operates on Value instances, not raw
  byte buffers directly. Fix 'defense in depth' paragraph.
- Fix ADR-097: add §3a defining TRecord 'values' property shape.
- Fix ADR-098: TTimestamp format ISO 8601→RFC 3339.
- Tighten OQ-071 impacts field: state what IS blocked, not just what
  isn't.

deepseek-v4-pro 85c5590001 docs(architecture): add alknet-typedef crate specs, ADRs 095-098, and OQs 069-071
Add the alknet-typedef architecture specification — the binary struct
engine that takes JSON Schema with TypeDef:* custom keywords and produces
offset maps, read/write functions, and validation.

Specs (docs/architecture/crates/typedef/):
- overview.md: purpose, 'schema is the format' principle, consumers, scope
- schema-layer.md: 17 TypeDef:* kinds, jsonschema integration, annotations
- layout-engine.md: two layout modes, three variable-length strategies
- data-access.md: read/write, TUnion dispatch, field paths, zero-copy
- validation.md: custom keyword validators, TypedefError, TypedefEngine

ADRs:
- 095: Purpose, scope, and the jsonschema engine
- 096: Two layout modes — packed sequential vs aligned static
- 097: Schema annotations — endianness, alignment, encoding, TUnion
- 098: Error handling and validation strategy

OQs (deferred(scope)):
- 069: Arrays of variable-length-element structs
- 070: no_std + alloc support
- 071: Builder API for schema construction

Index updates: README doc table + ADR table, open-questions.md theme
table + Deferred/Blocked section, overview.md crate graph.

Grounded in the alknet-typedef POC (26 tests passing) and the
call-channels-unification research. Reviewed by architecture-reviewer;
all critical issues, warnings, and suggestions addressed.

glm-5.2 0fcd5bc322 docs(adr): 094 — per-identity channel cap as DoS defense
ADR-076 framed the per-connection max_channels=256 cap as the DoS
defense, but a peer can open an unbounded number of transport
connections, so a per-connection cap bounds a connection's
reassembly-buffer cost, not a peer's total channels. The only coherent
unit for a channel DoS defense is the identity.

ADR-094 records the corrected design: a ChannelLifecyclePolicy trait
in channels-call (where the identity is already on OperationContext),
consulted by the channel/open handler (after AccessControl::check,
before allocation) and the channel/close handler (after the drain
completes). Default is PerIdentityChannelPolicy::new(256) — 256 per
PeerId across all the peer's connections, shared via Arc across every
channels connection a peer accepts. The cap is a peer concern (not
hub-specific), symmetric (both sides enforce), and lives in
channels-call because the channels layer is auth-blind by design
(ADR-075) — that is what makes it WASM-compatible, transport-agnostic,
and ALPN-blind.

For the hub-relay path (ADR-079), the spoke sees the hub as the direct
caller (ADR-032 — forwarded_for is metadata, not authority, for the cap
as for AccessControl::check), so the spoke caps the hub, not the
browser. A spoke serving a high-fan-out hub sets the hub peer's cap
higher via with_per_identity_caps — the spoke's own policy, not the
hub's. Recursive channels do not bypass the cap (the same policy can
be wired into the inner ChannelOperations).

ADR-076 is amended: the per-connection max_channels is reframed as a
per-connection memory bound (still returns channel:too_many_channels
when hit), the "DoS defense summary" table is removed, and the
"per-connection, not per-peer" line (the channels layer confessing a
hole and hoping the layer above would fill it) is corrected.

Spec docs updated to reference ADR-094: channel-operations.md gains a
"Per-identity channel cap" section (trait, default, enforcement
point, relay consequence, recursion); channels-adapter.md adds the
policy check as step 3 of the channel/open handler and the decrement
in channel/close; hub README adds the channel_policy field on Hub,
the with_channel_policy builder, a dedicated subsection, and the
inbound-peer-vs-hub-as-caller distinction; channels/README.md adds
ADR-094 to the Applicable ADRs table and a 9th Key Design Principle;
docs/architecture/README.md adds a Current State note and the ADR
table row.

glm-5.2 762d9c7bd2 docs(architecture): remove removed-thing remnants from spec docs
Spec docs should describe WHAT IS, not WHAT WAS. ADRs and OQ files are
historical records by design and are left alone; the ADR-index Status
column records ADR status (stable fact). What changed in the specs:

- API code blocks no longer list removed methods. ChannelClient::connect_quic
  (channel-client.md) and CallClient::connect (client-and-adapters.md) are
  gone from the impl blocks; surrounding prose describes the current
  from_connection / spawn_dispatch primary + AlknetClient dial shape.
- Amendment (ADR-093): stream_types field is removed blockquotes dropped
  from channel-client.md and channel-operations.md (the code already
  reflects the current state).
- Historical is-removed / reversed-by / amended-by prose rewritten to
  current state across channels crate, call crate, hub, tls, core,
  endpoint, client READMEs, and the top-level README/overview.
- Dropped the EndpointError — removed subsection from endpoint/README.md
  (the type doesn't exist anymore, so it shouldn't have a subsection).
- Replaced stale connect() references in flow descriptions with the dial
  (in AlknetClient) since connect() is no longer a method.
- Removed strikethrough ADR-028 / from_jsonschema-clause rows from
  client-and-adapters.md and operation-registry.md ADR tables.
- Rewrote the ADR-066 update blockquote in operation-registry.md to
  describe FromJsonSchema's current shape.

19 files modified, net -116 lines. No ADRs or OQ files touched.

glm-5.2 a3cb44968e docs(adr): 093 — channels pure channel multiplexing (8-byte header, no stream_type)
Prune the channels spec to reflect the stream-unification resolution
(docs/research/stream-unification/findings.md): the channels wire format
goes from 9 bytes to 8 bytes, the channels layer no longer carries a
stream_type concept, into_sub_streams() is removed, and TTY always uses
its 5-byte format (carried transparently in the channels payload).

ADR-093 is the umbrella decision (the channels-layer consequence of
ADR-092's BiStream handler leaf): every channel is a BiStream, the
handler owns its sub-stream multiplexing, the channels layer routes by
channel_id only. Amends ADR-071 (8-byte header, no stream_type),
ADR-074 (into_sub_streams removed, accept_bi yields BiStream), reverses
ADR-077 (TTY always 5-byte), and the channels-facing clauses of
ADR-072/073/075/076/080/081. Adds ADR-092 forward-reference note
(into_sub_streams preservation subsequently reversed by ADR-093) and
the missing ADR-092 cross-reference on ADR-070.

Adds OQ-68 (add/strip API shape — built-in vs utility; the contract is
decided in ADR-093, the function surface is open; two-way door, low
priority, decision-ready when the channels crate's implementation
begins).

Rewrites the 7 channels spec docs (README, overview, channels-wire,
channels-connection, channels-adapter, channel-operations, channel-client)
to describe the post-amendment shape as current, with the 8-byte header,
the add/strip composition, single accept_bi accessor, BiStream per
channel, and TTY-always-5-byte.

Touch-up cross-references in hub README, client README, ADR-085, and
the OQ-45/47/65 question files (TTY-internal stream_type 3 →
STREAM_CTRL_IN; channels 9-byte → 8-byte).

glm-5.2 c6eef730e4 docs(architecture): sync specs to post-extraction state (phases 0-5)
The crate-extraction migration (phases 0-5) is complete in the code;
the specs still carried forward/migration framing ("was welded",
"after the refactor", "currently duplicated", "does not exist yet",
"What moves from X to Y" tables, "Implementation ordering") that
described the migration rather than the resulting state. Updated 10
spec files to describe the current state cleanly.

Spec/code mismatches fixed:
- core/README.md: a stale paragraph said CallCredentials "stays in
  alknet-call" while ADR-091 Am. 2026-07-17 removed it. Now consistent.
- tls/README.md: TlsClientConfig API described a planned
  ClientVerifierContext + for_tcp_tls(&self) + rustls_config(&self);
  the actual code is new(&ConnectionCredentials, alpn) +
  for_quinn(self) + into_rustls_config(self). Updated to match.
- client/README.md, call/client-and-adapters.md: ConnectionCredentials
  field is tls_identity / with_tls_identity in the code, not
  local_identity / with_local_identity. Updated the specs describing
  the current API (ADR-091 body keeps local_identity as the decided
  name).
- client/README.md: dial_iroh description said the local key is
  "extracted from creds.local_identity" — the code uses the pre-built
  iroh endpoint's key (set at with_iroh time) and reads only
  creds.remote_identity for the NodeId. Fixed.
- overview.md: said core has "no quinn/iroh deps" — core keeps
  quinn/iroh for Connection::from_quinn/from_iroh. Fixed.
- call/client-and-adapters.md: a /// doc-comment block and
  pub struct RemoteIdentity were floating outside any code fence
  (orphaned closing backticks). Fixed.
- tls/README.md: TlsError sketch shows the full ADR-088 6-variant
  enum; the code has a simplified 3-variant enum. Added an
  implementation note flagging the divergence; ADR-088 shape kept as
  target.
- call/README.md: review note said "ADR-029 migration pending" (stale
  — migration landed). Updated to reflect phase 5 completion (pure
  protocol crate, no TLS/transport deps, verified against Cargo.toml).

Migration framing removed (present-state descriptions instead):
- tls/README.md: "What moves from" tables -> module-contents tables;
  "Implementation ordering / greenfield" section removed; "after the
  refactor" section -> "What AlknetEndpoint does"; references to
  extraction-source files (alknet-core/src/endpoint.rs,
  alknet-call/src/client/call_client.rs) replaced with current file
  locations (alknet-tls/src/{server,client,pem,signing}.rs).
- endpoint/README.md: "was two things welded" framing removed;
  "after the extraction" section -> "What alknet-core looks like".
- core/endpoint.md: "Historical summary" section removed; clean
  deprecation pointer.
- README.md, overview.md, open-questions.md: dates + present-tense
  cleanup.

deepseek-v4-pro e91d943857 docs: remove CallCredentials — dead field, dead from_call path, auth_token is per-request payload
ADR-091 amended 2026-07-17: CallCredentials removed (not retained in
alknet-call). Trace showed CallCredentials.auth_token had no reader
(connect() read only tls_identity + remote_identity; spawn_dispatch
takes no credentials; from_call's credentials_auth_token was a
different type, always None, never connected). auth_token is a
per-request payload field — browsers send it in the WS payload; the
HTTP gateway resolves bearer → Identity at its boundary.

from_call's credentials_auth_token dead path removed in the same pass
(OpSummary field, handler params, build_forwarded_payload param, and
the two tests asserting the never-exercised Some path).

ADR-089 §5 further amended, ADR-080 noted, all spec READMEs and
overview updated. Migration plan (findings.md) corrected: Phase 5
prune now includes CallCredentials removal + from_call dead-path
removal; test audit corrected (4 unchanged + 2 move to core, not 6
unchanged); integration-test split documented; all 'or' hedges
resolved.

glm-5.2 613bf680cd docs(arch): ConnectionCredentials decouples dial from call protocol (ADR-091) + migration plan cleanups
ADR-091: ConnectionCredentials — decouple the dial credential bundle
from the call protocol. CallCredentials (call-protocol-level, carries
auth_token) was being used as the dial's credential type, coupling the
dial to the call protocol. The auth_token is a hub-layer identity
correlation mechanism (browsers, alknet/register), not a transport
credential. ConnectionCredentials (transport-level: local_identity +
remote_identity) is the dial's credential bundle; all three dial
signatures unify on &ConnectionCredentials; dial_iroh's node_id
parameter is derived from remote_identity.fingerprint. CallCredentials
stays in alknet-call with auth_token. The shape is validated by the
future dial_ssh pattern (russh's check_server_key + authenticate_publickey
consume the same two dimensions).

Amends ADR-089 §3 (dial signatures) and §5 (move consequence), ADR-087
(input framing). Updates client/tls/call/core crate specs and the
extraction plan's Phase 0/3/4/5.

Migration plan cleanups (findings.md):
- Remove duplicated ordering-rationale bullets (copy-paste artifact)
- TL;DR: six phases -> seven (Phase 0 promoted); four compilable
  intermediate states -> each phase leaves workspace compilable
- Remove inline 'Wait — that's 10, not 8' self-correction; fix
  Category B header to (10 tests)
- Replace contradictory line ranges in Net Phase 5 test impact with
  name-based references
- Decide quinn feature fate: removed (not no-op)
- Note webpki-roots always-present per ADR-088 §5 in Phase 1 dep list

glm-5.2 bf6ce957c0 docs(arch): tighten tls/endpoint/client specs — remove connect/connect_quic, move CallCredentials to core, shed alknet-call TLS deps
Review of the three new crates (alknet-tls, alknet-endpoint, alknet-client)
+ revised core found compile-blocking inconsistencies, stale claims, and
dep-graph contradictions. All resolved:

Critical:
- C1: CallClient::connect / ChannelClient::connect_quic REMOVED (not
  delegated) — keeping them as thin wrappers over AlknetClient::dial_quic
  would make protocol crates depend on alknet-client, contradicting the
  dep graph. Callers compose dial + take-over (2 lines).
- C2: alknet-client feature gates now pull alknet-core/quinn +
  alknet-core/iroh (for Connection::from_quinn_with_alpn / from_iroh).
- C3: rustls-native-certs + webpki-roots added to alknet-tls deps
  (always-present, not feature-gated — CA-verify path is transport-agnostic).

Warning:
- W1: CallCredentials/RemoteIdentity moved to alknet-core (from
  alknet-call) — the dial must not depend on the call protocol; not a
  two-way-door, it determines the dep graph.
- W2: webpki-roots fallback implemented in spec (ADR-088 §5 added) —
  the code claimed a fallback that never existed; now the store is never
  empty, NoRootAnchors unreachable, containerized deployments work.
- W3: EndpointError removed entirely (BindFailed + HandlerNotFound both
  vestigial after ADR-083); shutdown() is now infallible.
- W4: FingerprintPinVerifier moved to alknet-tls (from alknet-call) —
  alknet-call sheds quinn/rustls/rustls-pemfile/rustls-native-certs
  entirely; CallClient becomes a pure protocol crate.

Plus: ClientError removed (only produced by removed connect); S1
(CallCredentials → ClientVerifierContext mapping + auth_token stripped
at TLS boundary documented); amendment notes on ADR-017, ADR-069,
ADR-080, ADR-082, ADR-087, ADR-090; overview crate graph + README index
updated.

glm-5.2 34e3be2801 docs(arch): resolve OQ-67 — iroh proxy force-relay-only + HTTP-to-SOCKS5 bridge (ADR-090 §5 amended)
The iroh-proxy POC (/workspace/iroh-proxy-poc, 5/5 runs clean) settled
OQ-67: iroh does NOT expose a socket-injection hook for the IP/direct
transport (noq_endpoint() is pub(crate), the IP transport binds its own
netwatch::UdpSocket, CustomTransport operates on a separate CustomAddr
address space iroh's hole-punching doesn't route through). The quinn
POC's Socks5UdpSocket does not transfer to iroh. The decision: force
relay-only when a proxy is configured, via three stable public iroh
Builder knobs — clear_ip_transports() + addr_filter(relay_only) +
proxy_url. The peer sees the relay's IP; the relay sees the proxy's IP;
the client's real IP is hidden on both surfaces. No iroh fork required.

Because iroh's proxy_url expects an HTTP CONNECT proxy (not SOCKS5),
the integration runs a tiny local HTTP-to-SOCKS5 bridge (~80 lines) so
a single Socks5ProxyConfig covers all three dials uniformly: UDP
ASSOCIATE for dial_quic, CONNECT for dial_tcp_tls, force-relay-only +
HTTP-to-SOCKS5 bridge for dial_iroh.

The POC also corrected a factual error: iroh's proxy_url proxies the
relay WebSocket only, not pkarr/DoH (those use pkarr/hickory-resolver
directly). Acceptable for the force-relay-only config (QAD disabled);
spec text corrected.

Force relay-only forgoes iroh's direct-path latency advantage (negligible
for the hub deployment, which runs its own relay) and makes relay
availability a hard dependency — the intended privacy/availability
tradeoff; a caller that prefers availability over privacy for the iroh
path simply does not set the proxy.

- ADR-090 §5 amended: iroh force-relay-only decision + proxy_url
  coverage correction + HTTP-to-SOCKS5 bridge
- OQ-67: resolved (force relay-only)
- client README: iroh proxy row, bridge, limitations, ADR/OQ entries
- README/open-questions: OQ-67 resolved, Current State amendment

glm-5.2 b7d67e5a5f docs(arch): client-dial SOCKS5 proxy seam — ADR-090, OQ-67
AlknetClient gains an optional SOCKS5 proxy (with_socks5_proxy) so a
native client can hide its real IP from the hub. dial_quic routes QUIC
through SOCKS5 UDP ASSOCIATE (validated by the /workspace/quinn-proxy-poc
PoC — quinn's AsyncUdpSocket + new_with_abstract_socket is the extension
point, 5/5 runs clean); dial_tcp_tls routes through SOCKS5 CONNECT. The
proxy is invisible above the dial (Connection, dispatch, credentials,
TLS config all proxy-unaware) and the no-proxy path is the zero-cost
default (socks5 feature + fast-socks5 dep are opt-in).

SOCKS5 is the sole proxy protocol (covers both TCP and UDP, so no HTTP
CONNECT variant needed). The two distinct SOCKS5 concepts — the
client-dial proxy (ADR-090, transport-layer privacy) and the planned
alknet-socks5 channels data-channel handler (ADR-085 scope, a service
one side offers the other) — compose at the SOCKS5 protocol level
without alknet-type-level coupling.

iroh is the exception: dial_iroh does not consume Socks5ProxyConfig —
iroh's proxy_url covers the relay-exposure surface, but the
direct-connection peer-exposure case is OQ-67 (deferred(unclear) — the
pieces exist but the iroh socket-stack composition isn't clear; does
not block the first hub deployment, which uses QUIC/TCP+TLS).

glm-5.2 8669594661 docs(arch): extract AlknetEndpoint into alknet-endpoint (ADR-083 Am. 2026-07-15)
Amend ADR-083 with the crate-extraction decision: the endpoint moves
from alknet-core into a new crate alknet-endpoint, mirroring the
alknet-client extraction (ADR-089). The ADR's shape (new + builder
methods + public dispatch + run/shutdown) is unchanged; only the
location changes.

The extraction is structural pruning, not an inline refactor. The
endpoint is a leaf consumer of core's shared types (zero handler crates
import it; 124 import sites for the other core modules). Extracting it
lets core shed quinn/iroh/rcgen/rustls-acme — handler crates no longer
transitively link those. A pure worker (client-only) does not pull
alknet-endpoint at all. The dep graph is symmetric: alknet-core is the
shared types crate; alknet-endpoint and alknet-client are the
server-side and client-side establishment crates.

New spec: crates/endpoint/README.md (the canonical endpoint spec).
core/endpoint.md is deprecated to a stub. Cross-references updated
across 8 docs (README, overview, tls, hub, client, core README, ADR-083,
ADR-089 references). Architecture review passed (3 critical, 9 warnings
— all addressed).

glm-5.2 ce7de57973 docs(arch): AlknetClient native dial seam — resolves OQ-55 (ADR-089)
Extract the deferred AlknetClient as a new crate alknet-client — the
client-side analogue of AlknetEndpoint. Three dial methods (QUIC +
TCP+TLS via TlsClientConfig, iroh via key) produce a Connection for
CallClient::spawn_dispatch / ChannelClient::from_connection to consume.
The deferral collapsed because ADR-086 gave the native endpoint type
three dial shapes within one endpoint type, ADR-087 broke the circular
hedge, and ADR-083 gave the server-side shape to mirror by symmetry.

Names the three concept layers that were tangled throughout the initial
development (deployment role / establishment side / ALPN-level category)
so the fix is legible. Names alknet/register as a dialable entry-point
ALPN (native registration, parallel to HTTP registration in OQ-58); its
wire protocol is deferred to OQ-66 (blocked on OQ-58's token model).

Cross-references updated across 11 existing docs (README, overview,
open-questions, OQ-55, tls, hub, core, channels README/overview/
channel-client, call client-and-adapters) to reflect OQ-55 resolved and
the new alknet-client crate. Architecture review passed (2 critical, 7
warnings — all addressed).

glm-5.2 1291a751b0 docs(arch): alknet-tls spec sanity-check fixes — client-side accessors, extraction tables, ordering
TLS spec review before task decomposition. The client side was
under-specified relative to the server side — fixed:

- W1+W2: TlsClientConfig gets the full accessor API (for_quinn,
  for_tcp_tls, rustls_config) mirroring TlsServerConfig, plus the
  local TlsIdentity input for client-auth cert presentation. Both
  clients (call + channels) consume it via the same three accessors.
- W3: Client-side extraction table for call_client.rs items that move
  to alknet-tls, including the Ed25519SigningKey / load_cert_chain /
  load_private_key duplicates that consolidate into one copy.
- W5: Server-side rustls_config() doc comment no longer claims iroh
  uses it (iroh reads the key directly).
- S6: Dropped 'remote cert type' from ClientVerifierContext — it
  doesn't drive any construction decision.
- S7: Implementation ordering note (tls first, then endpoint refactor,
  then assembly) — the call sites don't exist until step 2/3.
- N8: Noted alknet-core's acme feature + deps become vestigial.
- Flagged client spec work for the next session (two clients: call +
  channels; same TlsClientConfig shape; prerequisite for first hub).
- Advanced ADR-082/083 to Accepted; TLS README to reviewed.

glm-5.2 43b8179304 docs(arch): TlsError shape — single enum, owned by alknet-tls (ADR-088, resolves OQ-63)
Grounded in the actual error-producing call sites (endpoint.rs server
side, call_client.rs client side) and the dependency-crate sources read
from the cargo cache (rustls 0.23.41, rustls-pemfile 2.2.0, rcgen 0.13.2,
quinn-proto 0.11.15, rustls-acme 0.12.1).

Decision: single #[non_exhaustive] enum, one variant per failure
category, owned by alknet-tls (not re-exported from core). Six variants:
CertLoad(io::Error), SelfSigned(rcgen::Error), Rustls(rustls::Error),
VerifierBuild(VerifierBuilderError), QuinnWrap(NoInitialCipherSuite)
[quinn-gated], AcmeConfig(String).

Three findings drove single-enum over thin wrapper: (1) for_quinn()
fails with NoInitialCipherSuite, not rustls::Error — a rustls::Error
wrapper cannot represent the for_quinn() failure; (2) rustls_pemfile::Error
is not a std::error::Error (no Display, no Error impl) so #[from] would
not compile — pemfile BufRead APIs return io::Error; (3)
WebPkiServerVerifier::build() returns VerifierBuilderError, not
rustls::Error — a thin wrapper cannot represent empty-CA-root-store as
a first-class failure.

Deliberately NOT variants: ACME EventError/OrderError (stream events,
logged not returned from new); unknown-raw-key fail-closed (handshake-
time rejection at dial time, not a config-construction error —
corrects OQ-63's original framing); provider init (infallible); resolver
construction (infallible).

glm-5.2 77321a7e84 docs(arch): break the AlknetClient circular hedge — TlsClientConfig not blocked on dial (ADR-087, resolves OQ-64)
OQ-64 and OQ-55 were linked in a circular dependency: the client-side
TLS config was deferred behind the dial seam (OQ-55), but the dial
needs the TLS config. No second transport can dial until it has a TLS
config; the TLS config was deferred until a second transport dials.
Schrödinger's code — required and not required until observed.

ADR-087 breaks the circle by separating two concerns that were
conflated as 'the same seam':

1. TlsClientConfig — rustls::ClientConfig + ADR-034 verifier selection
   + ADR-084 crypto provider. Transport-agnostic. All decisions made.
   Buildable today. A PREREQUISITE for any dial, not a consequence of it.

2. The dial (AlknetClient::dial()) — transport-specific connection
   establishment. Extracting a transport-polymorphic dial from one
   shape (QUIC) would bake QUIC in. Legitimate deferral (OQ-55,
   unchanged).

The hub makes this non-optional: a hub dials out to workers it
supervises and to other hubs (hub-as-client). The first hub deployment
(web + native) dials workers over QUIC with the worker's fingerprint
pinned. There is no 'later' for the TLS config — it is on the critical
path for the first hub and for alknet-worker.

Changes:
- ADR-087: TlsClientConfig in alknet-tls, not blocked on OQ-55
- OQ-64: resolved (yes, alknet-tls provides TlsClientConfig)
- OQ-55: amended — only the dial seam is deferred; TLS client config
  is explicitly NOT part of the deferral
- TLS README: 'Server-only (for now)' section replaced with
  TlsClientConfig section; crate is no longer server-only
- Hub README: dial/supervision section references TlsClientConfig for
  outbound connections

glm-5.2 7d9b1ebad9 docs(arch): endpoint types and entry points (ADR-086) — resolves OQ-62
Name the three-endpoint-type model (web/native/iroh) and the
entry-point vs. endpoint ALPN distinction. This untangles the
hub/endpoint/ALPN-config confusion that OQ-62 hinted at:

- A hub composes a SUBSET of three endpoint types (web, native, iroh),
  each with its own identity model, auth model, and transport(s). A
  full hub runs all three; a minimal hub runs iroh alone (no public
  IP required). The first real use case is web + native. Corrects the
  hub README's 'must support TCP+TLS and QUIC' framing.

- ALPNs split into entry points (accepted without identity — h2,
  http/1.1, future alknet/register) and endpoints (identity required
  before dispatch — alknet/channels, alknet/call, alknet/ssh). This
  resolves OQ-62: split ALPN lists by endpoint type (Option B), because
  each endpoint type serves a different client class with different
  negotiable ALPNs. The assembly-layer wiring pattern is now guessable.

- Foundational handlers are two categories, not one: channels
  data-channel ALPNs (tunnel, socks5, fs, sftp — gated by channels,
  not in any TLS ALPN list) vs. SSH (an endpoint ALPN that wraps
  channels inside it, RFC 7250 keys, legacy compat, comes later).

Files OQ-65 (WebSocket carrying channels — the browser story update)
filed as a one-way-door question, open. ADR-048 is not superseded;
OQ-65 may extend it. The web config advertises alknet/channels by
default so the hub is ready if OQ-65 resolves to 'WebSocket carries
channels.'

glm-5.2 7610ec1f31 docs(arch): workspace scope correction (ADR-085) + tls spec review fixes
ADR-085 records the actual workspace scope: the mono-repo is the core
networking toolkit (substrate: core, tls, call, channels; deployment
shapes: hub, worker; foundational handlers: tty, http, ssh, tunnel,
socks5, fs, sftp; vault). Consumer repos (docker, agent) are separate
repos depending on the published core crates. The overview's crate
graph had been describing the wrong scope since ADR-003 — a flat
~12-crate workspace including DNS/messaging/NAPI while omitting
channels, hub, worker, and tls. This stale scope was a causal factor
in the 'assembly layer' hedging pattern: when the overview implies
everything lives in one repo but the architecture needs a hub/worker
composition layer not in the graph, the gap gets filled with
'assembly layer' as an escape hatch. The overview is rewritten to
match the real boundary.

TLS spec review fixes (from architecture review):
- C3: hub/worker/hub-worker terminology pointers (tls README + endpoint.md)
- W1: server-only statement + OQ-64 (client-side TLS helper, deferred)
- W2: ACME task lifecycle semantics (returns immediately, no first-cert await)
- W3: remove stale EndpointError::TlsConfig variant
- W4: update stale ALPN section for two-config hub
- W5: add alknet-tls to hub dep graph (assembly-layer dep)
- W6: trim inline rationale -> point to ADR-084
- W7: ADR-084 status dependency note

New open questions:
- OQ-62: ALPN list sharing for two-config hub (open, high)
- OQ-63: TlsError shape (open, high)
- OQ-64: client-side TLS helper (deferred, blocked on OQ-55)

glm-5.2 34729c7846 docs(arch): resolve OQ-59 (fingerprint stays in core) + ADR-084 (aws-lc-rs crypto provider)
OQ-59 resolved to Option A: fingerprint.rs stays in alknet-core. The
client-side FingerprintPinVerifier in alknet-call uses fingerprint
functions and must not depend on alknet-tls (which would pull TLS setup
infra into client-only deployments). The rustls dep in core is narrow —
production fingerprint code uses only sha2 + manual DER parsing; the
rustls::sign usage is a test helper only. alknet-tls re-exports the
fingerprint functions for convenience.

ADR-084: aws-lc-rs as the TLS crypto provider on all server + client
config paths. Records the decision that was already in the code (to
match iroh's tls-aws-lc-rs feature) but had no ADR. FIPS-capable, broad
platform support, consistent across quinn/iroh/TCP+TLS/client. Switching
to ring or process-default requires a new ADR. ADR-082's
behavior-preservation invariant now references ADR-084 for the decision
record.

glm-5.2 2abe8f1872 docs(arch): TCP+TLS as first-class owned transport — resolves OQ-60, dissolves OQ-61
ADR-083 revised: TCP+TLS moves from an external sibling loop calling
public dispatch to a first-class owned transport via
with_tcp_tls(listener, acceptor), running inside run() alongside the
quinn and iroh accept loops. The endpoint owns all its accept loops;
shutdown() stops them all. The multi-owner shutdown problem (OQ-61)
does not arise — dissolved.

The reason TCP+TLS was structurally excluded (ADR-010 Am. 1: the
endpoint built transports internally, TCP+TLS couldn't fit) is gone
after ADR-083 — the endpoint no longer builds transports; it runs
accept loops on whatever it's given. TCP+TLS is a listener transport,
same shape as quinn and iroh. ADR-010 Amendment 2 supersedes Am. 1's
struct-level exclusion.

dispatch stays public — but for genuinely external shapes (SSH channels,
future WebTransport streams), which are connection-internal multiplexing,
not listener transports. The listener-vs-multiplexing distinction is now
explicit.

OQ-60 resolved: the TCP+TLS loop lives in alknet-core behind a tcp
feature (owned by the endpoint); builder functions are inlined by the
assembly layer. A alknet-transport crate was rejected — it would contain
only trivial builders; the real component (the loop) is in core. Hub-
specific composition lives in the hub crate; transport runtimes that any
node might need live in core.

Updated: ADR-010 (Amendment 2), ADR-082 (TCP+TLS loop location), ADR-083
(revised), core/endpoint.md (struct + dispatch + shutdown), hub/README.md
(transport table + assembly example + stale sibling references),
tls/README.md (endpoint section + TCP+TLS loop location + references),
open-questions.md (OQ-60 resolved, OQ-61 dissolved).

Review: zero critical issues, five warnings fixed (stale hub README
prose, stale core endpoint.md struct/dispatch listings, stale ADR-082
TCP+TLS loop location, stale TLS README reference entry, hub front-matter
date).

glm-5.2 81bde6f28f docs(arch): endpoint as pure accept-loop runner + acme-tls/1 guard relocation (ADR-083, OQ-60/61)
ADR-083: AlknetEndpoint becomes a pure accept-loop runner with a public
dispatch method. Transport construction moves out of the endpoint — the
assembly layer reads StaticConfig, builds transports from
TlsServerConfig(s), and hands pre-built quinn/iroh endpoints to the
endpoint via with_quinn/with_iroh. TCP+TLS dispatch is first-class (same
dispatch path as quinn/iroh); ADR-010 Amendment 1's duplicated-dispatch
workaround is retired. StaticConfig stays in core as the assembly-layer
config; the endpoint takes only drain_timeout.

The acme-tls/1 guard moves from dispatch_quinn to the shared dispatch
method — ACME TLS-ALPN-01 challenges arrive over TCP (CAs validate via
TCP to port 443, not QUIC), so the guard's quinn-specific location was a
latent bug once TCP+TLS exists. The guard is transport-agnostic; the
rationale (no handler, silent close) is unchanged. ADR-027 §5 amended.

OQ-60: where build_iroh_endpoint lives (assembly layer / alknet-tls
helper / transport module). build_quinn_server_config_from_rustls is
decided — it moves to alknet-tls as for_quinn() per ADR-082; only
build_iroh_endpoint is genuinely undecided.

OQ-61: multi-owner shutdown coordination. Boundary committed (endpoint
owns dispatched handlers; assembly layer owns spawned accept loops);
mechanism open.

ADR-082 amended: drops the Arc<TlsServerConfig> endpoint signature
(superseded by ADR-083); keeps its scope as the alknet-tls crate's
TlsServerConfig + accessors.

Review: zero critical issues, five warnings fixed (build_iroh_endpoint
destination contradiction, undeclared shutdown_sender, missing ADR-027
amendment marker, underspecified dispatch no-match behavior, stale
door-type timing clause).

glm-5.2 192bd0a5a2 docs(arch): spec alknet-tls crate — shared TLS config across quinn + TCP+TLS + iroh (ADR-082, OQ-59)
The TLS setup in alknet-core is welded to quinn: build_rustls_server_config
produces a rustls::ServerConfig, then build_quinn_server_config_from_rustls
consumes it into quinn::ServerConfig — the rustls config is moved, not
shareable. ACME is worse: the AcmeState task is spawned inside the quinn
endpoint, so a TCP+TLS listener would need a second ACME state machine
(two orders for the same domain, two cert caches, Let's Encrypt
rate-limit risk).

alknet-tls extracts the TLS setup into a shareable TlsServerConfig:
- TlsServerConfig::new(identity, alpns) builds the rustls::ServerConfig
  once (including the ACME state machine if ACME)
- for_quinn() clones it for quinn (QuicServerConfig::try_from)
- for_tcp_tls() clones it for tokio-rustls (TlsAcceptor::from)
- rustls_config() borrows it for any other consumer
- One cert, one ACME state machine, N transports

TlsIdentity and Ed25519SecretKey stay in core (config types).
fingerprint.rs stays in core (shared by server endpoint + client
FingerprintPinVerifier in alknet-call — OQ-59 tracks whether it should
move; likely stays because moving would force alknet-call to depend on
alknet-tls, pulling TLS infra into client-only deployments).

iroh shares the key, not the rustls config — iroh has its own TLS built
into the Endpoint (takes iroh::SecretKey, not rustls::ServerConfig).
alknet-tls has no for_iroh() method; the assembly layer passes
Ed25519SecretKey to iroh directly.

Feature gates: quinn / tcp / acme as independent opt-ins. rustls always
present. tokio-rustls only when tcp. quinn only when quinn. rustls-acme
only when acme.

Files:
- crates/tls/README.md: crate spec (TlsServerConfig API, what moves/
  stays, feature gates, deps, behavior-preservation invariants)
- decisions/082-alknet-tls-extraction.md: the ADR (Proposed)

aws_lc_rs provider, verifier scheme list, acme-tls/1 ALPN;

glm-5.2 b0cc0a01b7 docs(arch): unweld CallClient from QUIC — spawn_dispatch primary, connect convenience (ADR-017 Am. 2026-07-13)
Same fix as ADR-080 (ChannelClient) applied to the call crate. The
existing code already had the right structure — spawn_dispatch is not
feature-gated (transport-agnostic), connect is #[cfg(feature = "quinn")]
— but the docs inverted the framing: connect was 'primary,' spawn_dispatch
was 'lower-level.' That welding masked the call protocol's
transport-agnosticism (ADR-012 EventEnvelope; ADR-065 from_stream/from_bidi
accept any AsyncRead + AsyncWrite).

Changes:
- client-and-adapters.md: reframe spawn_dispatch as the transport-
  agnostic primary constructor (one-way door), connect as the QUIC
  convenience (two-way door, feature-gated on quinn). Mirror the
  from_connection / connect_quic pattern from ADR-080/channel-client.md.
  Fix all 'QUIC-backed' / 'over QUIC' / 'opens a QUIC connection' framing
  to be transport-agnostic. Fix from_call description, adapter location
  map, exchange-of-operations example, Constraints section.
- call-protocol.md: 'runs over QUIC bidirectional streams' → 'runs over
  any ordered, reliable bidirectional stream.' Fix stream model, stream
  lifecycle (connection drop / stream reset now list all transports,
  not just QUIC). Fix CallConnection.connection doc comment.
- operation-registry.md: FromCall provenance comment 'QUIC forwarding
  stub' → 'call-protocol forwarding stub.' Fix from_call description.
- call README.md: fix client-and-adapters.md description, fix design
  principle #11 framing.
- ADR-017: add Amendment (2026-07-13) documenting the spawn_dispatch /
  connect reframe, mirroring ADR-080's amendment.
- overview.md, architecture README: update ADR-017 and
  client-and-adapters.md table summaries.
- OQ-015, OQ-007: fix 'opens QUIC connections' / 'bidirectional QUIC
  streams' framing in resolution text.

No code changes — spawn_dispatch and connect already exist with the
right feature-gate structure. This is a documentation reframe.

glm-5.2 a26401aadd docs(arch): rewrite hub README for multi-transport + channels substrate; add OQ-58 (worker registration)
The hub README predates channels (2026-07-09) and was built on the
call-protocol-directly-over-QUIC model: 'One QUIC connection per peer
carrying the call protocol,' CallClient::connect as the dial path,
QUIC as the only transport. The channels crate replaced that substrate
(ADR-071/079/080), and the hub's primary use case (worker provisioning
on docker/vast.ai/runpod) requires TCP+TLS for registration and QUIC
or TCP+TLS for the ongoing session — coexisting on one hub, not as
alternatives.

Rewrite:
- Multi-transport stated as decided: 'A hub MUST support TCP+TLS and
  QUIC endpoints simultaneously.' TCP+TLS accept loop (ADR-010 Am. 1)
  lives in the hub, shares the HandlerRegistry with the quinn endpoint.
- Channels substrate: the hub uses ChannelsAdapter/ChannelClient
  (from_connection primary, connect_quic convenience — ADR-080),
  not CallClient/CallAdapter directly. One channels connection per
  peer; CallAdapter runs on channel 0 (ADR-072).
- Transport-agnostic dial/accept: dial_worker_connection takes a
  Connection (one-way door); connect_quic_worker is a two-way-door
  convenience. supervise_worker takes a dial closure, not a SocketAddr.
- Identity over transports: fingerprint path (QUIC+raw-key,
  X.509 client cert) via resolve_from_fingerprint; bearer-token path
  (TCP+TLS no client cert, WebTransport, WebSocket) via
  resolve_from_token on the call first frame. Both resolve to the
  same PeerEntry (ADR-030/034).
- Worker registration flow (6 steps): provision → token → download →
  key gen → HTTP POST over TCP+TLS → channels connect. Step 4 is HTTP
  on HttpAdapter; step 6 is channels over QUIC or TCP+TLS. The hub
  creates a mixed-fingerprint PeerEntry (ADR-034 §3) at registration.
- OQ-58: worker registration flow — enrollment-token model,
  endpoint shape, register_worker API. Open (decision-ready, not
  blocked), one-way door, high priority.
- ADR-081: fix stale references to channels-hub/channels-worker
  sub-crates (the ADR's Decision says they don't exist; the References
  section said they did).

Review (architecture-reviewer): 3 critical (ADR-081 stale refs;
bearer-token extraction flow; assembly example QUIC-only +
unspecced into_connection), 7 warnings (registration 'or'→'both',
channel/control translation, OQ-52 interim, HubError variant naming,
RegistrationError definition, X.509-client-cert prose, adapter
ownership phrasing), 5 suggestions. All criticals and warnings #4/#7/#8
addressed; #5/#6/#9/#10 addressed; #11-15 noted as optional.

glm-5.2 73c621bf21 docs(arch): unweld ChannelClient from QUIC — from_connection primary, connect_quic convenience (ADR-080 amendment)
The channels protocol is transport-agnostic by design (ADR-071 substrate
modes; ADR-065 unwound the server-side QUIC-welding via
Connection::from_stream/from_bidi). ADR-080 had welded the client-side
one-way-door API to QUIC and masked it as a deferral ('QUIC-only
initially', 'can be generalized later') — anti-patterns #8/#9/#11
(door-type-as-deferral + resolved-with-escape-hatch). 'Can be
generalized later' meant 'can be rewritten later' — the expensive
reversal the one-way-door classification exists to prevent.

Fix: split the constructor surface.
- from_connection(connection: Connection) — transport-agnostic primary,
  one-way door. Mirrors server-side ChannelsAdapter::handle(Connection)
  and the existing CallClient::spawn_dispatch pattern.
- connect_quic(addr, credentials) — QUIC convenience, two-way door,
  additive. Future connect_tcp_tls / connect_webtransport join it
  without touching the one-way-door surface.

OQ-55 reframed: the deferred thing is the shared dial+TLS seam
(AlknetClient), not a QUIC-welded client API. The client take-over APIs
(CallClient::spawn_dispatch, ChannelClient::from_connection) are
transport-agnostic and decided; only the shared dial across transports
is blocked on a second transport's dial existing.

Files:
- decisions/080-channelclient.md: amendment section, Decision code
  block, Transport-agnostic by construction (replaces QUIC-only
  initially), Consequences, Door type, subscribe_resources added to
  Decision block (was referenced by Door type but missing)

glm-5.2 fd83fc1685 docs(arch): channels substrate simplification + stream_type decomposition + sub-crate split
Three simplifications to the channels spec, all flowing from the review:

1. Substrate simplification (ADR-071 revised): the 9-byte chunk header is
   used in ALL substrates — in-line (TCP+TLS, WebTransport), native (QUIC
   bidi streams), and multi-connection. The ChannelsAdapter reads headers
   off every bidi stream it accepts; the transport's native multiplexing
   is a performance optimization (independent flow-control windows), not a
   protocol change. One wire format, one code path, one handler experience.
   The channel_id in the header is the correlation key across substrates.

2. Stream_type decomposition (ADR-071 revised): every stream_type is
   unidirectional. Bidirectionality is two stream_types (write + read), not
   one 'bidirectional' stream_type. Grouped in threes: 0/1/2 = data
   write/read/err, 3/4/5 = control write/read/err, % 3 formula. This
   resolves the TTY control channel's 'not actually bidirectional' flaw —
   control is now 3 (write, client→server) + 4 (read, server→client), each
   with its own reassembly buffer and EOF. Channel 0 uses [0,1] (call frames
   bidirectional via 0=in, 1=out). TTY uses [0,1,2,3,4]. ADR-072, 073, 074,
   077 updated for the new stream_type assignments.

3. Sub-crate decomposition (ADR-081 new): channels-core (pure multiplexer —
   wire format, demux/mux, ChannelBidiStreamSource, ChannelManager; depends
   on alknet-core only, no call dependency, ALPN-blind) / channels-call
   (channel 0 pre-negotiation + lifecycle op registrations; depends on
   channels-core + alknet-call) / channels-hub (relay) / channels-worker
   (ChannelClient). Isolates the call-protocol coupling from the pure
   multiplexer so the dependency graph is honest.

ADR-077 (TTY inside channels) updated: TTY now uses 5 sub-streams [0,1,2,3,4]
with control properly bidirectional via 3/4; amends ADR-052's stream_type
assignments for direct mode too (direct alknet/tty now uses 0-4, not 0-3).

Spec docs updated: channels-wire, channels-connection, channels-adapter,
channel-operations, overview, README.

glm-5.2 2313c51f12 docs(arch): add alknet-channels specs — ADRs 071-080, 7 spec docs, OQ-56/57
Phase 1 architecture for alknet-channels (multiplexing proxy on
alknet/channels). Grounded in the completed de-risk POC (28 tests) and the
landed ADR-070 (BidiStreamSource trait + Connection::from_source).

ADRs:
- 071: 9-byte chunk wire format (generalizes TTY's 5-byte)
- 072: channel 0 pre-negotiated as alknet/call (no special control plane)
- 073: channel lifecycle operations on the call protocol — channel/open,
  close, control, resources/subscribe; direction field pinned; subscribe
  from day one (not poll-for-v1 — StreamingHandler machinery exists)
- 074: ChannelBidiStreamSource implements BidiStreamSource (ADR-070);
  into_sub_streams() typed accessor for TTY; accept_bi() generic path
- 075: ChannelsAdapter + ChannelManager; REQ-CH-01..04 wire invariants
- 076: bounded-buffer backpressure (1 MiB), 256-channel cap, monotonic IDs
- 077: TTY inside channels uses sub-streams, not own wire format;
  amends ADR-052 scope to direct-connect TTY; channels feature on tty
- 078: two-pump shutdown-on-completion contract (handler-level)
- 079: hub relay translates channel 0, byte-forwards data channels
- 080: ChannelClient (QUIC-only); AlknetClient core extraction deferred (OQ-55)

Spec docs: overview, channels-wire, channels-connection, channels-adapter,
channel-operations, channel-client.

OQ-56 (full windowing) and OQ-57 (two-pump helper extraction) are genuine
deferred(scope) deferrals with concrete blocking conditions; the contracts
are decided, only the extensions are deferred.

Hedging audit converted three research hedges into decisions:
resources/subscribe (not poll), server-assigned IDs (not if-zero-RTT),
bounded-buffer (not if-HOL-becomes-a-problem).

glm-5.2 f8f5f27ce0 docs(arch): land ADR-070 BidiStreamSource + OQ-55 AlknetClient deferral + impl task
Three core-crate changes surfaced by the alknet-channels POC:

- ADR-070: extract BidiStreamSource trait so Connection holds
  Box<dyn BidiStreamSource> instead of a closed ConnectionKind enum;
  downstream crates (channels, future transports) implement the trait
  to add connection shapes without editing core. Public Connection API
  preserved verbatim. REQ-CORE-02 (close() params clippy warning under
  --no-default-features) folded in — the signature stays on the trait,
  non-QUIC impls ignore the args.

- OQ-55: AlknetClient / client establishment extraction deferred(scope).
  Blocked on a second *transport's* real client (not a second QUIC
  client) — extracting a QUIC-shaped connector now would bake QUIC in
  as the establishment shape, the same welding ADR-065 unwound on the
  server side. Each crate builds its own client standalone for now.

- core-types.md / auth.md / overview.md / README indexes updated to
  reflect ADR-070 and OQ-55. Architecture review: zero critical issues.

- tasks/core/bidistreamsource-trait.md: the implementation task (Parts
  1-3: BidiStreamSource refactor, close() fix, AuthContext::anonymous).

glm-5.2 87b2c2a5ef docs(arch): hub-wiring cluster — aggregated env, peer_operations, from_call cleanup, alknet-hub crate spec
Three ADRs addressing gaps surfaced by the first hub consumer (alkapi):

- ADR-067: Aggregated peer-env wiring — Dispatcher::with_aggregated_env hook
  so compose_root_env reads a shared PeerCompositeEnv across all calls,
  not a fresh per-call one. The hub-defining gap (alkapi OQ-08 / G.1).

- ADR-068: PeerCompositeEnv::peer_operations override — adds
  list_operation_names() to OperationEnv, overrides on OverlayOperationEnv
  and PeerCompositeEnv. Fixes services/list-peers returning empty operation
  lists for non-local peers (alkapi G.6).

- ADR-069: from_call is a manual free function, not auto-wired — reverses
  the aspirational OQ-27 resolution to match the implementation. Cleans
  the 'v1 default' hedging language in ADR-017 and client-and-adapters.md
  (alkapi G.4).

New crate spec: alknet-hub — reusable hub pattern (aggregated env,
connection lifecycle, worker supervision with backoff, service discovery).

Spec fixes: builder API drift (with_local/with_local_streaming separation),
ScopedOperationEnv → ScopedPeerEnv type name, OQ count 51→54.

Three new OQs: OQ-52 (wait_for_close), OQ-53 (backoff defaults),
OQ-54 (inbound hook placement).

glm-5.2 97456bc608 docs(arch): ADR-066 — move from_jsonschema to alknet-http as HTTP-backed single-endpoint adapter
from_jsonschema was in alknet-call as a schema-only placeholder with a
NOT_FOUND handler — broken (an op in the registry needs a real handler)
and in the wrong crate (alknet-call has no HTTP client; a useful
from_jsonschema needs reqwest like from_openapi). ADR-066 moves it to
alknet-http as a real reqwest-backed single-endpoint adapter for
non-standard/non-OpenAPI REST endpoints, functionally similar to
from_openapi but one endpoint at a time. FromJsonSchema provenance
stays in alknet-call (now a handler-bearing leaf).

- New ADR-066 (supersedes ADR-017 §5 from_jsonschema clause + ADR-022
  FromJsonSchema row; both amended with strikethrough + pointer)
- Updated specs: call/client-and-adapters, call/README,
  call/operation-registry, http/http-adapters (new from_jsonschema
  section), http/overview, http/README, arch README + overview
- New task: tasks/http/adapters/from-jsonschema.md (depends on
  from-openapi; includes alknet-call cleanup of the broken placeholder)
- Old task tasks/call/client/from-jsonschema.md marked superseded

glm-5.2 2aa6363e57 docs(arch): sync specs to transport generalization sweep (ADR-064, ADR-065)
Three code commits landed a clean sweep discovered when building an
external app against the crates. This syncs the architecture specs to
match the codebase and amends the affected decisions.

ADR-064 (supersedes ADR-005): irpc was never integrated — no .rs file in
the workspace ever imported it. The wire protocol (wire.rs) is hand-rolled
length-prefixed JSON; the EventEnvelope shape was derived from the
@alkdev/pubsub TypeScript prior art (ADR-013), not from irpc. ADR-005's
premise ('irpc as the call protocol foundation') was never implemented as
stated. Superseded with a clear header; the body is kept as historical
record.

ADR-065: Connection::from_stream / from_bidi — Connection now accepts any
AsyncRead + AsyncWrite pair via ConnectionKind::Stream (yield-once
accept_bi contract: QUIC yields many streams, everything else yields one
then ConnectionClosed). Unblocks TCP+TLS, SSH channel dispatch,
WebTransport streams, and wasm streams through the same HandlerRegistry
as QUIC connections, with zero handler code changes. MockConnection /
ConnectionKind::Mock removed (tests use from_stream with sink/empty).
Stream-level Mock variants renamed to Stream (they were already generic).

Amended ADRs: ADR-003 (irpc removed from dep table), ADR-007 (from_stream
opens the server-side door; MockConnection removed), ADR-010 (TCP+TLS can
now dispatch through the registry via from_bidi; iroh 1.0 migration noted).

Updated specs: core-types.md (Connection/SendStream/RecvStream sections),
endpoint.md (TCP section, iroh note), call-protocol.md, operation-registry
(irpc Integration section replaced), overview.md, http-server.md,
webtransport.md, call README. OQ-09 (WASM) resolution amended: the
Connection door is now open via from_stream; the accept-loop runtime door
remains closed (tokio doesn't run on WASM).

glm-5.2 1ce11717d8 docs(arch): draft alknet-docker architecture specs (ADRs 058-063, OQs 048-051)
Greenfield architecture spec set for the alknet-docker crate — a thin,
single-host bollard wrapper exposing docker container/image operations
as call-protocol ops on the shared alknet/call ALPN, plus a
DockerTtyBackend (impl TtyBackend) behind a tty feature for interactive
terminal sessions into containers over alknet/tty.

Six ADRs:
- 058: docker ops on alknet/call (no separate ALPN; raw-carriage handoff
  dissolved by alknet-tty extraction — interactive attach moved to
  alknet/tty via DockerTtyBackend, no carriage field on call.requested)
- 059: bollard 0.21 (verified current on crates.io) + feature selection
  (http+pipe+time; no ssl/ssh/websocket/buildkit)
- 060: container resource model (ADR-050 application) — alknet.managed/
  alknet.owner labels, list owned_only flag, hosted-services operator
  role via static-resource fallback, handler-driven revoke with
  autonomous-death tolerance, resource-action vocabulary
- 061: DockerTtyBackend in alknet-docker behind tty feature (attach vs
  exec mode; POC drive_attach_raw as reference)
- 062: Docker client + OwnershipStore injection via closure capture
  (not Capabilities, not OperationContext — matches from_openapi pattern)
- 063: exit code on terminal call.responded for non-interactive exec
  (call.completed stays empty, ADR-012 unchanged)

Four spec docs (crates/docker/): README, overview, docker-operations,
docker-tty-backend. Four deferred-scope OQs (048-051): network/volume
ops, buildkit, system events subscription, create options surface.

Updates the tty-backend.md Backend implementations table (DockerTtyBackend
row now specced) and the architecture README (doc table, ADR table,
current-state paragraph, OQ count).

Grounded in the alknet-docker POC (docs/research/alknet-docker/poc-summary.md)
which validated the hard parts; the remaining lifecycle ops are mechanical
bollard wrapping. Reviewed by architecture-reviewer subagent; criticals
(the docker_client injection model conflicting with the Capabilities
contract) resolved via ADR-062/063 before commit.

glm-5.2 dbac972aaa docs(arch): ADR-057 — alknet-tty does not depend on alknet-call (self-contained negotiation framing)
The earlier specs claimed alknet-tty reuses alknet-call's
FrameFramedReader/FrameFramedWriter 'framing utility' (ADR-052 §6,
ADR-003 Am. 1). A pre-implementation sanity check found this was
unsound: FrameFramedReader::read_frame() is hardcoded to deserialize
EventEnvelope — the length-prefix read and the type-specific deserialize
are one entangled call, not a separable utility. alknet-tty's
negotiation payload is a NegotiateRequest, not an EventEnvelope, so the
claimed reuse did not exist in a usable form.

ADR-057: alknet-tty implements its own ~30-line length-prefixed
framing directly on tokio AsyncRead/AsyncWrite. The format coincides
with alknet-call's framing by convention (both are length-prefixed
JSON); the implementations are independent. alknet-tty depends on
alknet-core only — no alknet-call dependency. The ~30 lines of framing
is an idiom, not a domain abstraction worth a cross-crate dependency.

Updates:
- ADR-003 Amendment 2: clarifies alknet-tty does not depend on
  alknet-call; the Am. 1 protocol-foundation exception remains for
  alknet-http/agent/napi (actual type reuse), not alknet-tty.
- ADR-052 §6: framing is self-contained in alknet-tty; format coincides
  by convention, not by code reuse.
- overview.md: dependency block drops alknet-call; new 'Why no
  alknet-call dependency' subsection explains the unsound-reuse finding.
- tty-wire.md, tty-backend.md, tty README, crates/tty/README.md,
  top-level README: ADR tables, Design Decisions tables, and dependency
  edges updated to reflect alknet-core-only dependency.
- ADR-053, ADR-054: References updated to ADR-003 Am. 2 + ADR-057.

glm-5.2 25f0f55592 docs(arch): alknet-tty spec sanity-check fixes — TtyControlHandle newtype (C1), backend cleanup contract (W1, ADR-056), clarifications (S1-S5)
C1: Box<dyn TtyControl + Clone> does not compile (Clone is not object-safe).
Replace with a TtyControlHandle newtype: #[derive(Clone)] wrapping
Arc<dyn TtyControl + Send + Sync>. The trait stays object-safe; the
newtype carries the Clone-ability. Updated across tty-backend.md,
ADR-053, OQ-43, and the tty README.

W1: 'Drop is the cleanup, threads exit on channel close' was false for
the local PTY waiter thread (blocked in Child::wait(), does not observe
channel close) — a child that ignores stdin EOF would be orphaned on
session cancel. New ADR-056 commits a backend cleanup contract: dropping
the exit_code future MUST kill the session target. The local backend
implements it via a ChildKiller held in the exit_code future's Drop
guard (disarmed on resolve). Corrected the lifecycle section in
tty-adapter.md, added the mechanism + constraint to tty-local.md, and
referenced ADR-056 from tty-backend.md, overview.md, both READMEs.

S1: error-frame < 16 MiB stated as a wire-format invariant (not an
assumption) so the 0x00-first-byte disambiguation trick is sound by
construction.
S2: carriage field validation (MUST be "raw" in v1, else
malformed_negotiation) specified.
S3: NegotiateRequest + TerminalParamsWire Rust structs added with
serde defaults and validation rules.
S4: modes field annotated 'backends MUST ignore content in v1' in both
tty-backend.md and ADR-053.
S5: AsyncWrite/Stream qualified with crate origins (tokio::io,
futures_core) in the TtyHandle struct definitions.

glm-5.2 1baa619ce9 docs(arch): decompose open-questions.md into per-OQ files under questions/
The monolithic open-questions.md (1310 lines, 47 OQs) was large enough to be
unmanageable, with high size variance (OQ-42 at 220 lines next to OQ-06 at 8).
Decomposed into one file per OQ under docs/architecture/questions/ (NNN-slug.md,
mirroring the ADR convention), with open-questions.md retained as the index:
theme-grouped tables plus a cross-theme Deferred/Blocked section that surfaces
the 6 deferred OQs with their Blocked-on conditions inline (the safe-exit
visibility surface). Per-OQ content moved verbatim; all 62 inbound links stay
valid (none used anchors). README's curated OQ summary dropped (now redundant
with the index tables).

Also seeds tasks/architecture/ with this task plus two follow-ups found during
the decompose: OQ-09/10 missing structured Blocked-on fields, and the
tasks/architecture/ blocker-task half of the Safe Exit protocol being
unenforced.

glm-5.2 e4e6ccfb14 docs(arch): alknet-tty Phase 1 specs — wire format, backend trait, local backend, exit-chunk ordering
Grounded in the alknet-docker POC (seed codec) and the alknet-tty POC
(2026-07-05, validated the control channel, the local-PTY blocking→async
bridge, and the signal-delivery contract).

Four ADRs:
- ADR-052: wire format — alknet/tty ALPN, two-carriage (JSON negotiation
  then raw chunks), fixed channel set 0-3, control as JSON, negotiation-
  error framing disambiguation
- ADR-053: TtyBackend trait + TtyHandle — the backend inversion point;
  exit_code as a Future; REQ-TTY-01 (backends need not be natively async)
- ADR-054: local backend as alknet-tty-local sibling crate behind a
  feature re-export; PTY vs pipe per-session; runner pattern preserved
- ADR-055: exit code on a stream_type 3 control chunk; "exit chunk is
  last" invariant; adapter owns the ordering

Five component specs (crates/tty/): README, overview, tty-wire, tty-
backend, tty-adapter, tty-local. The docker/SSH backends are future
crates (out of scope); the trait shape is committed so they can be
built against it.

Five OQs (OQ-43…47): two resolved (TtyControl Clone, stdin closure),
two deferred(scope) (terminal modes, runner API surface), one open
low-risk (flow control).

Zero critical issues from a general-subagent architecture review;
warnings addressed (inline rationale trimmed to ADR refs, TtyError and
StdinCmd defined, framing disambiguation documented, missing ADRs added
to index tables).

glm-5.2 193f3a0e24 docs(arch): ADR-051 — YAML input format for from_openapi (gap-fill; JSON-first detection, yaml_serde dep)
from_openapi's spec already stated the contract as "JSON/YAML doc" but the
implementation only delivered the JSON half. vast.ai publishes a YAML
OpenAPI schema, which surfaces the gap. This is gap-filling against an
existing constraint — no architecture invariants touched (OpenAPISpec
stays serde_json::Value-based, forwarding handler / no-env-vars / error
fidelity / to_openapi output unchanged).

ADR-051 records: (1) from_yaml + format-detecting from_str constructors;
(2) JSON-first/YAML-fallback detection as a correctness rule (YAML 1.1
coerces yes/no/on/off to booleans — running JSON through YAML would
silently corrupt string fields); (3) yaml_serde dependency (maintained
official-YAML-org fork of deprecated serde_yaml, not feature-gated);
(4) to_openapi output stays JSON (scope boundary).

Specs updated to reference ADR-051 by number (http-adapters, overview,
both README ADR tables). Implementation task added at
tasks/http/adapters/from-openapi-yaml-input.md.

glm-5.2 f6ddd37433 docs(arch): add ADR-050 — dynamic resource ownership for runtime-spawned resources
Writes OQ-42's five decisions into ADR format:

1. Storage: reuse the repo/adapter pattern (ADR-033, fourth instance
   alongside IdentityProvider/IdentityStore/CredentialStore). New traits:
   OwnershipProvider (sync read, hot-path) + OwnershipStore (async write,
   handler lifecycle). In-memory default; persistence adapter additive.
2. Integration: AccessControl::check consults the ownership provider
   directly (Option 2). OperationSpec gains resource_id_path (JSON pointer
   into the input). Backward-compatible — ownership=None falls back to
   the static Identity.resources path.
3. Access pattern: proxy-only. Spawner owns, proxy to share via from_call
   + forwarded_for (ADR-032), teardown revokes. No grant mechanism in
   core. Future grant is additive (new trait method), stated as
   reversal-cost classification, not deferral.
4. Four edge specifics: list = scope-gate + result-filter; teardown =
   automatic, handler-driven; fleet = per-node ownership, downstream app
   tracks 'who is this for'; composition = two orthogonal checks,
   ADR-015/022 unchanged.

Reviewed: zero critical issues. Two warnings fixed (None-handling in the
check sketch, missing ADR-004 cross-ref). One suggestion applied
('v1 mechanism' → 'initial mechanism' to avoid hedging misread).

glm-5.2 13dd15ab0b docs(arch): resolve OQ-42 — proxy-only ownership model for runtime-spawned resources
Lock in the dynamic resource ownership model for runtime-spawned
resources (containers, TTYs, runner workspaces). Three decisions:

1. Storage: reuse the repo/adapter pattern (ADR-033, fourth instance
   alongside IdentityProvider/IdentityStore/CredentialStore) with an
   in-memory default adapter; sync read on the dispatch hot path.
2. Integration: AccessControl::check consults an ownership provider
   directly (Option 2); OperationSpec gains resource_id_path (JSON
   pointer into the input) so the spec is fully self-describing for
   authorization.
3. Access pattern: proxy-only — spawner owns, proxy to share via
   from_call + forwarded_for (ADR-032), teardown revokes. No grant
   mechanism in core; 'poking holes' is a downstream-app concern. A
   future grant is additive (new trait method), stated as reversal-cost
   classification, not deferral.

Four edge specifics pinned: list = scope-gate + result-filter; teardown
= automatic, handler-driven; fleet = per-node ownership, downstream app
tracks 'who is this for'; composition = two orthogonal checks, ADR-015/022
unchanged.

Removes the prior hedging language ('decision direction set', 'open for
the ADR') and the contingent qualifiers from specifics 3/4 now that the
proxy-vs-grant call is made. The dependent crate specs (docker, tty,
runner, fleet) can declare their AccessControl shapes against this model.

glm-5.2 f390550a06 docs(arch): set OQ-42 decision direction — repo/adapter storage + Option 2 integration
Two structural decisions for dynamic resource ownership (OQ-42), recorded
in the OQ so ADR drafting starts from a clear position:

1. Storage side reuses the repo/adapter pattern (ADR-033) — a fourth
   instance alongside IdentityProvider/IdentityStore/CredentialStore.
   Trait in alknet-core with an in-memory default adapter; persistence
   adapter separable. Sync read with ArcSwap + honker-NOTIFY cache
   invalidation, same shape as ConfigIdentityProvider (ADR-035). No new
   shape invented; no Phase 0 needed for the storage side.

2. Integration point is Option 2 — AccessControl::check consults the
   ownership provider directly. Rejected Option 1 (augment identity with
   a per-request snapshot) because its purity was theatrical — the
   question 'can X exec into container C' was never purely a function of
   identity, it just looked that way because the resource set was static.
   Option 2 makes check's signature honest about what ACL checking is in
   the presence of dynamic resources. Cost is a check signature change
   (one-way door, every call site updates) — implementation cost, not
   semantic cost, per the project's decision principle.

Refinement that makes Option 2 clean: OperationSpec gains resource_id_path
(JSON pointer into the input, e.g. '$.containerId'). Fits naturally with
the existing JSON-Schema-backed input_schema — the pointer is within an
existing schema on the same spec. OperationSpec becomes fully
self-describing for authorization: resource type, action, and which input
field drives the resource lookup, all declared on the spec.

Four specifics remain open for the ADR: the no-specific-resource (list)
case, teardown coupling, fleet representation (spoke resources on the
hub), and composition interaction with dynamic ownership. These were
surfaced by choosing Option 2 rather than by leaving the integration point
undecided.

glm-5.2 e29672942c docs(arch): record OQ-42 — dynamic resource ownership for runtime-spawned resources
The alknet-docker POC research surfaced that containers are a natural
AccessControl resource, but the resource set is dynamic (containers are
created at runtime) and ownership is derived from creation — which the
current static Identity.resources model (config-sourced via
PeerEntry/CompositionAuthority) doesn't fit. The issue generalizes to
every crate that spawns a thing at runtime and exposes it over the call
protocol (docker, tty, opencode-runner wrapper, alknet-container fleet
layer); solving it per-crate would diverge. Recording as OQ-42 in the
centralized tracker with the generalized framing so the architecture
workflow sees it: one-way door at the model level (core/call), two-way
at the mechanism level, high priority, blocks the dependent crate specs.
A Phase 0 research/POC pass is likely warranted before the ADR.

glm-5.2 7ecc11610a docs(arch): ADR-049 — streaming handler for subscription operations
The call protocol spec describes streaming (call.responded*N +
call.completed, PendingRequestMap::Subscribe, CallConnection::subscribe),
but the server-side Handler type returned a single ResponseEnvelope —
a Subscription op had no way to produce a stream. The TS predecessor
(@alkdev/operations) had separate OperationHandler / SubscriptionHandler
types; the Rust port collapsed them, losing the streaming path. This
restores it end-to-end: StreamingHandler type, HandlerKind on
HandlerRegistration validated against op_type, invoke_streaming() on
OperationRegistry, server-side dispatch branches on op_type, new
INVALID_OPERATION_TYPE protocol code for wrong-dispatch-path misuse,
GatewayDispatch::invoke_streaming() for /subscribe SSE, from_call stream
forwarding via CallConnection::subscribe(), from_openapi SSE forwarding.
OperationEnv::invoke() stays request/response-only (stream composition is
handler-level, not protocol-level). Amends ADR-023's protocol-code list
(five → six). Tracks the stream-operators library as OQ-41 (feature
extension, not an unmade decision).

glm-5.2 b71db99753 docs(http): add ADR-048 and websocket.md — WS carries native session, not gateway
Promote the WebSocket browser path from a section in http-server.md to a
first-class spec (websocket.md) and commit the contract-pattern decision
(ADR-048): a WS connection carries the native EventEnvelope call-protocol
session, not the HTTP gateway shape. The gateway endpoints are HTTP-only;
discovery on WS is via services/list/services/schema as ordinary call-protocol
ops; subscriptions project as native call.responded events (no SSE).

ADR-044 already decided WS as the v1 browser bidirectional path; ADR-048
clarifies the shape of what ADR-044 committed (§1 implies native session;
the ADR makes it an explicit implementer-visible rule). The from_wss adapter
(importing a remote node's ops over WS) is recorded as out-of-scope with a
concrete reversal trigger so it is not re-derived later.

Spec cleanup: http-server.md WS section collapsed to a stub pointer;
websocket.md Why section references ADRs rather than re-arguing them;
length-prefix decision made canonical (no prefix on WS — message boundary
is the delimiter); default upgrade path pinned (/alknet/call) with HTTP/2
extended CONNECT noted; indexes (README, http/README, overview) updated.

glm-5.2 2a6e4c371a docs(http): resolve OQ-39; add ADRs 045-047; record pubsub prior art for WS path
OQ-39 (to_openapi published-spec versioning) resolved by ADR-045:
info.version semver tracks the gateway endpoint contract, not the
operation set — per-caller operations discovered via /search do not
bump the version. The gateway pattern (ADR-042) dissolved most of the
original churn concern.

ADR-046: assembly-layer custom HTTP routes on HttpAdapter. The HTTP
router had no documented extension point for deployment-specific
endpoints (e.g., an OAI-compatible proxy at /v1/chat/completions). Adds
extra_routes: Option<Router> at construction; raw HTTP, not operations;
default surface takes precedence on collision. The mechanism is the
one-way door; specific routes are two-way.

ADR-047: remove the direct-call POST /{service}/{op} HTTP surface. The
gateway /call is the sole invoke path — the simplified contract is a
few fixed endpoints, not a per-operation REST tree. The direct-call
surface re-introduced the 'dump the full API regardless of privs'
failure mode at the HTTP level that the gateway /search was built to
escape. ADR-036's routing decision is superseded; its non-routing
clauses (SSE, Bearer auth, /healthz, stealth, error mapping) survive.
A deployment wanting a REST-like per-operation surface builds it as a
custom route projection (ADR-046).

ADR-044 updated with the tradeoff framing (WSS is the right tool for
the call-protocol-from-browser case; WebTransport is the right tool for
the generalized ALPN-stream-proxy case we don't have yet — coexist, not
migrate) and the @alkdev/pubsub concrete prior art (the EventEnvelope
{type,id,payload} the call protocol was derived from already has a
working WebSocket client/server; the sync is a small adjustment, not a
from-scratch build).

call-protocol.md references the pubsub lineage for the
transport-agnosticism claim.

glm-5.2 3327d585da docs(http): resolve OQ-40 reqwest client config — ClientWithMiddleware + retry/retry-after middleware stack
OQ-40 resolved: alknet-http owns a shared reqwest_middleware::ClientWithMiddleware
(not a bare reqwest::Client) with a two-layer middleware stack —
RetryTransientMiddleware (reqwest-retry, exponential backoff on transient
failures) + inlined RetryAfterMiddleware (from melotic/reqwest-retry-after, MIT,
~50 lines, inlined to bound the upstream's unbounded HashMap storage). The two
are complementary: reqwest-retry's default strategy does not honor Retry-After.

Hot-reload is rebuild-and-swap via ArcSwap (same pattern as
ConfigIdentityProvider, ADR-035); a rebuild drops the connection pool, which
is acceptable since a config change wanting a fresh pool is the trigger. The
three one-way constraints stand unchanged: alknet-http owns its client (no
env-var config, no shared global), credentials inject per-request from
OperationContext.capabilities, outbound TLS uses the system trust store.

Records the downstream layering boundary: the agent crate's provider SSE
normalization (the solid part of aisdk's pattern — Vercel-UI-message
normalization) sits on top of this client, consuming the reqwest::Response
stream; it does not replace the client. The aisdk core/client.rs reference for
client construction is dropped (env-var config + hand-rolled retry are the
anti-patterns discarded); the from_openapi.ts SSE normalization reference in
the forwarding-handler section is kept (separate, solid pattern).

No ADR — the decision is internal to alknet-http: the client type does not
cross crate boundaries (alknet-call never sees reqwest), the library choice is
reversible, and it does not touch the system's structure, constraints, or
cross-crate API surface.

Updates: http-adapters.md (HTTP client section rewritten, references updated,
constraints/OQ bullets updated), http-mcp.md (OQ-40 status flip), open-
questions.md (OQ-40 resolved with full config-shape table), README.md (OQ-40
folded into the existing two-way-doors bucket), and three secondary docs
(crates/http/README.md, overview.md, http-server.md) that carried stale 'open'
OQ-40 references.

glm-5.2 125cb49cc4 docs(http): defer h3/WebTransport (ADR-044); browsers use WebSocket for v1
Working through the WebTransport implementation path surfaced a scope
question distinct from the hedging-as-deferral anti-pattern ADR-038 was
written to correct. Three findings drove the re-evaluation:

1. The browser bidirectional call-protocol path doesn't require
   WebTransport — WebSocket is full-duplex, EventEnvelope fits a WS
   binary message boundary cleanly, and the Dispatcher is stream-
   agnostic (ADR-012). What WebTransport gives over WebSocket (native
   multi-stream multiplexing, the ALPN-as-stream substrate) benefits the
   proxy use case, not the call protocol.
2. WebTransport is a draft standard (-07, not RFC) on an experimental
   Rust dependency stack (wtransport/h3 both self-describe as not
   production-ready). Either choice puts a draft protocol on the
   security surface of the first release.
3. The ALPN-stream-proxy (ADR-040) is speculative — its WASM parser
   consumers (browser SSH/SFTP/git clients) don't exist yet, and the
   downstream crates WebTransport deferral blocks (SSH, git, SFTP)
   expose their ALPNs natively over QUIC regardless.

This is a scope decision (per ADR-009: a decision that 'genuinely
doesn't need to be made yet because the use case isn't concrete'), not
hedging. The reversal trigger is concrete: a real deployment needing
the ALPN-stream-proxy.

ADR-038 is superseded (its anti-pattern correction stands; its specific
'h3 in scope now' decision is reversed). ADR-040 and ADR-043 are
parked, not superseded — their designs revive unchanged when WebTransport
revives, with §2 (bidirectionality) and §3 (no-PeerId overlay) of ADR-043
transferring to WebSocket for v1.

ADR-044 §5 also states the 'browser is not a peer' rationale that
ADR-034 §4 closed without arguing: peer = addressable node in the
call-protocol peer graph (stable PeerId, PeerRef::Specific-reachable,
identity stable across reconnects), not 'any endpoint that exchanges
calls during a live session.' A browser is the second but not the first
(no stable crypto identity of its own, ephemeral, not addressable from
other nodes). ADR-034 §4 and Assumption 2 are amended by reference.

The wtransport-vs-hyperium dependency question is recorded (not
resolved — WebTransport is deferred) in ADR-044 §'Research note' and
webtransport.md so the revival doesn't re-derive it: wtransport probably
isn't the right choice (axum-bridge friction — it owns its own HTTP
serving path); the hyperium stack (h3 + h3-quinn + h3-webtransport) fits
the axum integration better but its server-side WebTransport API needs
verification before commitment.

Reviewed by architecture-review subagent; all critical cross-reference
issues (ADR-034 §5 stale 'in scope' assertion, ADR-036 Context listing
h3 as implemented, webtransport.md Design Decisions table) resolved.

glm-5.2 0a78306686 docs(http): add ADR-043 WebTransport bidirectional ALPN substrate; fix spec drift from mid-spec pivot
A consistency review of the alknet-http specs found two classes of
issues: internal contradictions from the mid-spec pivot (the to_openapi
gateway pattern landed in prose but not in cross-references), and a
systematic client→server assumption that only holds for the OpenAPI/MCP
case leaking into the WebTransport architecture.

Class 1 (internal contradictions):
- C1: to_openapi was half-refactored — body described the ADR-042
  gateway pattern but the decisions table and ADR-036 still said
  'paths mirror /{service}/{op}'. ADR-036's to_openapi clause is now
  amended as superseded by ADR-042; the stale decisions row and README
  Principle 2 are fixed.
- C2: the axum Router route list didn't include the 5 gateway endpoints
  (/search, /schema, /call, /batch, /subscribe). Added them; clarified
  /openapi.json as the gateway description doc; added gateway paths to
  the decoy exclusion list.
- C3: ADR-034 §5 still talked about the 'h3/WebTransport deferral
  bucket' that ADR-038 eliminated. Amended §5/Consequences/References
  to drop the deferral framing (the auth-model decision stands; only
  the 'when' wording was stale).

Class 2 (one-way direction assumption):
- C4/C5/C6: the WebTransport specs framed the session as browser→hub
  one-way, when the call protocol is bidirectional and WebTransport is
  a general ALPN transport substrate. New ADR-043 reframes WebTransport
  as a bidirectional ALPN transport substrate (call protocol is the
  first/canonical target; needs no WASM parser), names the call
  protocol's bidirectionality over WebTransport sessions, and states
  the inbound no-PeerId connection-local overlay as the mirror of
  ADR-034 §2. webtransport.md is updated to reflect this framing;
  ADR-040 is repositioned (not superseded) as the substrate's non-call-
  ALPN mechanism.
- C7: the HTTP/1.1+HTTP/2 surface's one-directionality is now named as
  a lossy consequence of HTTP request/response; WebTransport is named
  as the surface that restores the bidirectional call model.
- C8: overview.md acknowledges the from/to direction model is
  OpenAPI/MCP-specific, not a call-protocol property.

A review subagent pass on ADR-043 + webtransport.md found no critical
issues; warnings W1-W3 (residual browser-as-subject framing, ADR-009
rationale in spec, opening abstract tone) and suggestions S2/S4/S5
were addressed.

glm-5.2 69ebe58bab docs(http): add ADR-042 OpenAPI gateway pattern for to_openapi
The to_openapi spec was describing one OpenAPI path per alknet operation
— the inverse of from_openapi. That inverse is genuinely messy: the call
protocol's input is a flat JSON object, and generating a traditional
OpenAPI path entry (POST /fs/{path} with path param, body, query params)
requires reverse-engineering which fields are path/query/body — metadata
the call protocol doesn't carry. The three options (leaky HTTP metadata
on OperationSpec, fragile heuristics, manual annotation) are all messy.

ADR-042 replaces this with the gateway pattern (same as ADR-041 for
to_mcp): to_openapi generates 5 fixed endpoints (search, schema, call,
batch, subscribe) that gate access to the full operation registry. The
input is always a flat JSON body — no path/query/body split to
reverse-engineer. JSON Schema is already in the OperationSpec.

The per-caller API surface is the key advantage: /search is
AccessControl-filtered, so the client sees only what it can call. The
Gitea failure mode (dumping admin ops to every caller in a static
OpenAPI doc) is structurally impossible — the per-caller surface is the
default, not an afterthought. OpenAPI has no per-caller filtering
concept; the gateway pattern provides it through /search.

Gateway endpoint set:
- /search -> services/list (AccessControl-filtered, names + descriptions)
- /schema -> services/schema (full OperationSpec)
- /call -> call.requested (Query/Mutation, flat JSON body)
- /batch -> multiple call.requested (correlated IDs)
- /subscribe -> call.requested (Subscription, SSE) — the one endpoint
  the MCP gateway excludes (MCP is request/response; OpenAPI/SSE
  supports streaming)

A traditional per-operation-paths projection is additive (a deployment
that wants the nice Swagger UI builds it with HTTP-specific metadata),
not a replacement. The gateway is the default.

http-adapters.md to_openapi section rewritten: the gateway endpoint
set, per-caller filtering, error fidelity on the /call endpoint, and
the additive traditional projection. The 'Why' section adds the
flat->structured and per-caller-surface rationale.

glm-5.2 5fc074713c docs(http): add ADR-041 MCP tool-gateway pattern for to_mcp
The to_mcp spec was describing one MCP tool per alknet operation — the
tool-bloat problem. An LLM connecting to a node with 200 operations gets
200 MCP tools dumped into its context, degrading reasoning and wasting
context budget.

ADR-041 replaces this with the tool-gateway pattern (same pattern as
opencode's memory and worktree tools): to_mcp exposes 4 fixed meta-tools
(search, schema, call, batch) that gate access to the full operation
registry. The LLM has a few tools in context, discovers operations on
demand through search + schema, then calls. Same principle as Linux's
man command — don't preload all documentation; query on demand.

Gateway tool set:
- search -> services/list (names + descriptions, AccessControl-filtered)
- schema -> services/schema (full OperationSpec for a specific op)
- call -> call.requested (Query/Mutation only, request/response)
- batch -> multiple call.requested (correlated IDs, OQ-14)

Subscription operations are excluded — MCP tool calls are
request/response by protocol design (the client blocks until
CallToolResult returns); streaming subscriptions don't fit. Subscriptions
are filtered out of search results and cannot be invoked via call.

http-mcp.md to_mcp section rewritten: the gateway tool set, Subscription
exclusion, and the service behavior (tools/list returns 4 fixed tools,
tools/call dispatches through the gateway). The 'Why' section adds the
tool-bloat rationale and the memory/worktree tool pattern that informed
the design.

glm-5.2 398e3d512d docs(http): add ADR-040 WebTransport ALPN-stream-proxy and reframe OQ-38
The 'WebTransport proxy' concept was conflating two distinct things;
this pass separates them:

1. In-process ALPN-stream-proxy (ADR-040, in alknet-http): the h3 handler
   hands a WebTransport stream to another ALPN handler (SshAdapter,
   GitAdapter, etc.) as a Connection, so a browser with a WASM parser
   can reach any ALPN service via WebTransport. Path-based routing
   (the CONNECT path declares the target: /alknet/ssh -> SshAdapter).
   HttpAdapter gains Arc<HandlerRegistry> for the lookup. The browser's
   WASM parser implements BiStream (ADR-007) over the WebTransport
   stream. SSH-over-WebTransport is HTTPS-shaped at the network layer
   (anti-censorship: the 'VPN-like without being a VPN' use case on a
   clean foundation). russh-sftp demonstrates WASM targeting is
   feasible; SSH is the next target.

2. Standalone relay service (OQ-38, future alknet-relay crate): a full
   relay - fork of iroh-relay - with WebTransport proxy fallback for
   NAT traversal. This is infrastructure, not a mode of the h3 handler.
   OQ-38 reframed to be the standalone-relay scope question (distinct
   from the in-process proxy now resolved by ADR-040).

webtransport.md updated: three stream destinations (call protocol,
ALPN-handler proxy, other sub-protocols) with path-based routing; new
'ALPN-stream-proxy' section covering the WASM client side, auth model
(bearer token gates the session; protocol's own auth gates the
protocol session), and the HandlerRegistry reference.

README/overview ADR tables and OQ summaries updated for ADR-040.
