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.

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 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 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 5941280bca fix(agents): break the hedging-at-the-root pattern — deferred(unclear), impacts field, reviewer detection
Address the root cause of rework-causing hedging: the architect was
put in a logical bind where it couldn't express justified uncertainty
('the pieces exist but the shape isn't clear yet'). The only options
were 'decide now' (premature) or 'deferred(scope)' (false — the
information isn't missing, it's un-synthesized). The agent picked
deferred(scope) with a circular blocking condition (OQ-64 blocked on
OQ-55, OQ-55 needs OQ-64) because there was no honest way to say 'I
can see the pieces but I can't see the shape.'

Changes to the architect role spec:
- Add deferred(unclear) state: the pieces exist but the composition
  isn't clear; resolution requires investigation (work through
  examples, POC), not waiting. Has an investigation target and an
  impacts field.
- Add 'Impacts' field to the OQ format: what does this block
  downstream? Be specific ('blocks the first hub deployment because
  the hub dials workers' not 'blocks the hub crate'). The triage
  signal that makes deferral urgency visible — the field that would
  have made the AlknetClient circular hedge visible.
- Add circular-reasoning guard to self-review: 'check that your
  blocking condition isn't a prerequisite of the thing you're
  deferring.'
- Trim anti-patterns #9-#11 (hedging synonyms catalog, ~40 lines):
  detection belongs in the reviewer, not the architect's self-review.
  The architect is too close to its own reasoning to see its own
  circular hedges.
- Trim door-types section (30→10 lines): keep the one-paragraph
  summary, cut the elaboration.

Changes to the architecture-reviewer role spec:
- Add Decision Quality (F) category: false-deferral check
  distinguishing three cases — (1) hedging on a resolved decision, (2)
  false deferral / circular hedge (the blocking condition is a
  prerequisite of the thing being deferred), (3) legitimate deferral.
- Add Impacts Field Coverage (G) category: check that unresolved OQs
  have specific impacts fields.
- Note: the Decision Quality category is often the highest-value
  check on poorly-defined projects — the architect cannot self-review
  it (circular reasoning is invisible from inside the circle).

Retrofit existing OQs:
- Add Impacts field to all 16 unresolved OQs (10 deferred, 6 open).
- Update OQ-63 (TlsError shape) to reflect ADR-087's client-side
  addition — the error type now covers both server and client
  variants.
- Move OQ-65 (WebSocket carrying channels) to alknet-http theme
  (done in prior commit; this commit adds its impacts field).
- Verified: no circular reasoning found in existing deferrals. The
  AlknetClient hedge (OQ-64) was the circular one; it's already
  resolved by ADR-087.

glm-5.2 bd9ae3cb68 docs(arch): move OQ-65 (WebSocket carrying channels) to alknet-http theme
OQ-65 is about the WebSocket browser path — an alknet-http concern. It
surfaced during the TLS/ALPN-list discussion in passing (because the
web config's ALPN list needed to account for whether alknet/channels
is advertised), but the question itself lives with the WebSocket
spec, not with TLS or the hub. Remove from alknet-hub and alknet-tls
theme tables; add to alknet-http.

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.

  stays, feature gates, deps, behavior-preservation invariants)

  fingerprint.rs stay in core or move to alknet-tls? open, two-way,
  likely stays)

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)
- crates/channels/channel-client.md: from_connection primary API,
  Transport-agnostic by construction section, OQ-55 relationship
- crates/channels/overview.md, crates/channels/README.md,

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).

deepseek-v4-pro deea6de38a docs(arch): remove channels from hub spec — channels are research-phase, not specced
The channels concept (docs/research/alknet-channels/phase-0-findings.md)
was developed in a separate session and is research-phase, not
architecture. The hub spec was inadvertently built assuming a channel
model that doesn't exist yet.

Changes:
- Remove all channels references from hub README (subtitle, channel
  model section, channel management bullet, channel proxying section,
  'does NOT do' bullet, references)
- Remove OQ-55 (channel/open operation) — channels research has its
  own question tracking (OQ-CH-01 through OQ-CH-07)
- Hub spec now describes what it actually provides: peer lifecycle,
  aggregated operation env, service discovery. One QUIC connection
  per peer carrying the call protocol. No channels, no future
  multiplexing, no research references.
2026-07-11 07:52:02 +00:00
deepseek-v4-pro 5d56bae1ba docs(arch): fix inbound worker hook — callback inside handle(), not post-hoc
- Replace on_worker_connected() post-hoc call with WorkerConnectedCallback
  that fires inside CallAdapter::handle(). handle() blocks until disconnect
  — there is no 'after handle accepts' point for the assembly layer to
  hook into. The callback carries both on_connected (from_call + attach_peer)
  and on_disconnected (detach_peer + drop channels).

- Add CallAdapter::with_worker_connected_callback(callback) builder method.

- Consolidate duplicate WorkerConnectedCallback struct definitions.

- Fix channel role: 'channel proxying' → 'channel management'. The hub
  tracks channels; it does not proxy streams. What the caller does with
  the resulting channel is the assembly layer's business.

- Resolve OQ-54: callback is the committed design. Update OQ file and
  open-questions.md table.
2026-07-11 07:46:00 +00:00
deepseek-v4-pro b38b1d28a7 docs(arch): channel model — call protocol as control plane, any ALPN as data plane
Replace the 'future strategies' section with the channel model:

- Channel 0 is the call protocol — the universal control plane. Handles
  operation discovery (from_call), operation routing (invoke_peer),
  service discovery, and channel negotiation (channel/open, channel/close,
  channel/list).

- Channels 1..N carry any ALPN as data planes. Opened via channel/open on
  the call protocol. Each channel is a bidirectional QUIC stream, wrapped
  as Connection::from_bidi (ADR-065), and handed to the same
  ProtocolHandler::handle() that handles dedicated connections. The
  handler does not know it's on a multiplexed channel.

- Channel negotiation is symmetric — either side can open a channel.
  Same pattern as from_call: bidirectional, symmetric, negotiated over
  the call protocol.

- The hub's role for channels 1..N is transparent stream proxying. The
  hub does not interpret the protocol; the client and worker speak the
  ALPN directly.

- Hub struct gains channel tracking (PeerId → ChannelId → ChannelInfo).
  HubError gains ChannelAlreadyOpen, ChannelNotFound, ChannelOpenFailed.

- New OQ-55: channel/open operation spec (deferred to call-protocol
  implementation phase).

glm-5.2 ab963d0e46 docs(arch): resolve OQ-050 — include docker/system/events in v1
Resolve the deferred docker system events subscription question.
docker/system/events is now a v1 Subscription operation using the
same StreamingHandler pattern already wired for logs, exec, and
image/pull. The internal ownership-store subscription for stale-entry
cleanup on destroy events is a follow-up refinement.

Scrub hedging language from ADR-060 and docker specs:
- Remove 'marginal gain' / 'future feature is additive' framing
- Replace 'no reaper' / 'not promptly cleaned up' with clean
  statement that events subscription provides the prompt-cleanup path
- Remove stale-entry policy from ADR-060's two-way door classification

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 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).

See docs/research/transport-generalization/findings.md for the full trace.

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 db4da1e6f0 docs(arch): resolve OQ-45 — no application-level windowing; QUIC per-stream flow control suffices
The backpressure chain is complete by construction: QUIC flow control
→ bounded drainer channel → bounded stdout channel → OS pipe/PTY buffer
→ process write() blocks. Every link awaits its producer; no unbounded
buffer breaks the chain. The reversal path (an additive ControlMessage
variant, not a wire-format header change) is noted in ADR-052's
consequences as a two-way door, not the expected path.

Tightened ADR-052 assumption 1 from a hedge ('expected to work; a POC
would confirm') to a decided constraint. Updated all OQ-45 references
across the tty spec docs from 'open (low risk)' to 'resolved'.
2026-07-07 09:36:18 +00:00
glm-5.2 df5d04af1d tasks(arch): adopt taskgraph for architecture work — blocker tasks for deferred OQs, level mapping, status fixes
Establishes the tasks/architecture/ blocker-task half of the Safe Exit
protocol. Each deferred OQ now has an external-trigger tracker task
representing its unblocking condition, and the OQ's Blocked on field names
the tracker task ID — closing the gap where the deferral field existed but
the task-graph half was unenforced.

Changes:
- Add 6 external-trigger tracker tasks for the deferred OQs (OQ-09, 10, 32,
  41, 44, 46) under tasks/architecture/, tagged [external-trigger, deferred-oq]
- Add structured Blocked on field to OQ-09 and OQ-10 (previously used legacy
  'deferred' status with the reason in the Resolution prose); index now
  surfaces all 6 deferred OQs with concrete conditions, no placeholders
- Document the architecture-task level mapping (level: implementation for
  ADRs/specs, decomposition for spec-to-ADR breakdown, planning for backlog
  seeding, research/review direct fits) and the deferred-OQ blocker-task
  pattern in docs/sdd_process.md
- Mark architecture/safe-exit-blocker-task-mechanism and
  architecture/oq-09-10-blocking-conditions completed (implemented by this pass)
- Fix 4 pre-existing ADR-050 implementation tasks: status: done → completed
  (taskgraph enum is 'completed', not 'done') — taskgraph validate now passes
  for all 100 tasks

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 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 3daecd7ab2 fix(process): add architect Safe Exit for deferred decisions, clean hedging language
- Add Safe Exit section to architect spec: when a decision genuinely can't
  be made, mark OQ as deferred(scope) with concrete blocking condition,
  create blocker task, move on
- Add anti-patterns #10-#11 covering hedging synonyms (feature extension,
  additive, not a v1 blocker, for now, resolved with escape hatch)
- Add hedging audit to architect self-review checklist
- Clean hedging language from resolved OQs (OQ-04, OQ-13, OQ-14, OQ-16)
- Reclassify OQ-32 and OQ-41 as deferred(scope) with blocking conditions
- Add deferred(scope) status to OQ format in sdd_process.md

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 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 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.

glm-5.2 ab47dac4ad docs(http): draft alknet-http architecture specs and ADRs 036-039
First speccing pass for alknet-http (HTTP interface crate: h2/http1.1/h3
server + from_openapi/to_openapi/from_mcp/to_mcp adapters).

Specs (crates/http/):
- README.md, overview.md — crate index, two-roles-in-one-crate framing,
  adapter location map, feature gates (h3, mcp), no-env-vars invariant
- http-server.md — HttpAdapter for h2/http1.1, axum over QUIC stream,
  Bearer auth, SSE projection for subscriptions, /healthz, stealth decoy
- http-adapters.md — from_openapi (reqwest) and to_openapi (projection),
  error fidelity (HTTP_<status> per ADR-023), type definitions
- http-mcp.md — from_mcp/to_mcp (feature-gated), streamable-HTTP-only
- webtransport.md — h3/WebTransport handler, browser streaming path,
  HTTP/3 request vs WebTransport session distinguished at framing layer

ADRs:
- ADR-036 HTTP-to-Call Operation Mapping (Proposed) — direct path
  mapping; to_openapi is projection, not router (the load-bearing one-way
  door from Phase 0 DH-3)
- ADR-037 MCP Stdio Transport Exclusion (Proposed) — streamable HTTP
  only; stdio is not built (RCE-vector security position)
- ADR-038 HTTP/3 and WebTransport as First-Class HTTP Transports
  (Proposed) — corrects the Phase 0 DH-2 deferral framing; h3 is in
  scope, not deferred, per ADR-009 §'What this framework is NOT'
- ADR-039 HTTP Server and Client Host Colocated in alknet-http
  (Proposed) — one crate for server + client host (shared HTTP deps,
  shared operation-spec->HTTP mapping)
- ADR-003 Amendment 1 — clarifies alknet-call is a protocol-foundation
  crate (the alknet-http -> alknet-call dependency edge)

Open questions (OQ-38, OQ-39, OQ-40 added under 'Theme: alknet-http'):
- OQ-38 WebTransport relay-as-proxy scope (genuine scope question, not
  a deferral — the decision is made when the use case becomes concrete)
- OQ-39 to_openapi published-spec versioning (one-way after first
  publication)
- OQ-40 reqwest client config and connection pooling (two-way-door)

glm-5.2 0de2cebb1d docs(arch): ADR-035 — concrete persistence adapter shapes, resolve OQ-36
Commits the concrete adapter shape deferred by ADR-033: read-sync /
write-async split with honker NOTIFY/LISTEN for no-restart cache
invalidation, against SQLite, in a separate alknet-store-sqlite crate.

Two constraints drive the design: (1) the hot-path read trait
(IdentityProvider::resolve_from_fingerprint, CredentialStore::get) is
sync — called in the accept loop, no .await — so a SQLite-backed
adapter must cache in memory and serve sync reads from the cache; (2)
auth changes must take effect without a restart (an early issue the
project already fixed for ConfigIdentityProvider via ArcSwap config
reload). honker's SQLite NOTIFY/LISTEN (single-digit-ms wake, no
polling) is the cache-invalidation mechanism that makes both hold:
write commits to SQLite + emits NOTIFY, the running process's LISTEN
wakes, the in-memory index reloads and atomically swaps, the next
read sees the new state. Same ArcSwap-reload pattern as config,
generalized from 'config file is source of truth' to 'SQLite is
source of truth, honker signals when it changed.'

New async IdentityStore write trait (put_peer / update_peer /
remove_peer) extends the sync IdentityProvider read trait for peer
mutations. ConfigIdentityProvider does NOT implement it (config
reload is its write path — a posture enforced by the absence of a
backend, not a type-system constraint); SqliteIdentityProvider
implements both. CredentialStore::put/delete refined to async (within
ADR-031's one-way door — the contract was get/put/delete keyed by
provider persisting EncryptedData never decrypting; sync-vs-async was
unspecified). CredentialStoreError renamed to shared StoreError
covering both traits.

alknet-store-sqlite is one crate implementing both IdentityStore and
CredentialStore with shared SQLite connection + honker LISTEN infra
(splitting later is a two-way door). Schema shape committed (one row
per PeerEntry with JSON columns for fingerprints/scopes/resources;
one row per EncryptedData blob keyed by provider); exact DDL is an
implementation-detail two-way door in the adapter crate. The keypal
adapter-factory pattern is intentionally not ported to Rust (runtime
column-mapping is a TS affordance; in Rust each adapter is a concrete
type, cross-cutting concerns are a shared helper module).

Amends ADR-031 (put/delete async refinement, StoreError rename),
ADR-033 (concrete adapter shape now specified, two-crate framing
collapsed to one), ADR-034 (OQ-36 now resolved), auth.md (IdentityStore
section, cache-invalidation summary, OQ-36 reference), config.md (two
write paths note), and the OQ-36/OQ-34 entries in open-questions.md.
Review fixed 4 criticals (error-type name divergence, duplicate
IdentityProvider sketch, upsert/Duplicate ambiguity, 'shape unchanged'
contradiction), 7 warnings, 5 suggestions.

glm-5.2 6cc8715ccf docs(arch): ADR-034 — outgoing-only X.509 and three peer roles, resolve OQ-37
Untangles the conflation of three distinct remote roles under 'X.509
endpoint': (1) public X.509 endpoint — a remote HTTPS/call-over-TLS
server the local node is a client of (no PeerEntry, no PeerId, not in
the peer graph; CA verification + bearer token); (2) transport relay —
iroh's DERP-equivalent, infrastructure, not an alknet peer; (3) hub /
hosting node — an alknet peer that also exposes a public domain + X.509
for browsers (mixed-fingerprint PeerEntry, already supported by
ADR-030).

The load-bearing one-way door is the client-side verifier selection
rule: known peer (PeerEntry present) → fingerprint pin; unknown X.509
remote → CA verification (WebPkiServerVerifier); unknown Ed25519
remote → fails closed. This closes the AcceptAnyServerCertVerifier
security hole OQ-29 flagged, with the peer-model criterion (PeerEntry
presence) made explicit. The 'make PeerEntry symmetric' instinct is
rejected — pure-client connections to public APIs have no stable
logical identity to pin.

Documents that CallCredentials.remote_identity: None is load-bearing
(None = public X.509 endpoint → CA path, not a missing field; Some =
known peer → fingerprint pin), closing a subtle gap where an
implementer could have defaulted to a placeholder or treated None as
skip-verify.

Records WebTransport relay-as-proxy (deferred with h3/WebTransport,
new OQ-HTTP-07) and on-chain/smart-contract peer discovery (fits the
OQ-36 repo/adapter pattern, no auth-model change) so they aren't lost.

Amends auth.md and client-and-adapters.md with the three-role naming,
the verifier selection rule, and the Option semantics; updates OQ-37
to resolved in open-questions.md, README.md, and both crate READMEs.

glm-5.2 3f011cbb82 docs(arch): tighten door-type framing — reversal cost, not deferral
ADR-009, open-questions.md, and the architect agent spec all had the same
conflation: 'two-way door' was phrased as 'can be decided during
implementation,' which reads as 'defer the decision.' That's not what it
means. A two-way door is a decision you make now and can revert later if
wrong — it's about reversal cost, not urgency.

ADR-009: add §'What this framework is NOT' — explicitly separates door
type (reversal cost) from deferral (scope management). State that
architecture decisions are the architect's regardless of door type.
Reword the two-way-door process from 'can be decided during
implementation' to 'pick the simplest option that works, implement it,
revert if needed.'

open-questions.md: reword the header to clarify door type describes
reversal cost, not urgency. Add 'Door type is separate from whether a
decision is made.'

architect.md: add Key Principle #8 (decisions are made, not deferred),
a new 'Door Types and Decision Urgency' section, and two new anti-patterns
(#8: door type as deferral, #9: hedging language in resolved decisions).

glm-5.2 7d812af8f4 docs(arch): multi-credential PeerEntry, resolve OQ-29, dissolve OQ-35, add OQ-37
Amend ADR-030 with three changes from the auth-type analysis:

1. PeerEntry is now multi-credential: fingerprints: Vec<String> (Ed25519
   and/or X.509) + auth_token_hash: Option<String> (bearer token). All
   resolve to the same peer_id. A peer that authenticates via Ed25519
   today and via auth_token tomorrow gets the same PeerId. The 'peer
   bearer vs auth bearer' distinction was wrong — the correct framing is
   the three credential types (Ed25519, X.509, bearer token) and whether
   the token needs a stable logical id across rotation (PeerEntry) or not
   (ApiKeyEntry).

2. Fingerprint normalization (§6): quinn extracts the raw Ed25519 public
   key from the SPKI cert and formats as ed25519:<hex>, matching iroh.
   The same key has the same fingerprint regardless of transport. X.509
   fingerprints stay as SHA256:<hex of DER>. This also simplifies the
   coming WebTransport relay work.

3. The 'API keys' section is replaced with 'Bearer tokens' — correctly
   framing the three auth types and the two bearer-token paths
   (PeerEntry.auth_token_hash vs ApiKeyEntry).

Resolve OQ-29 (CallClient TLS client-auth): wire quinn client-auth (present
Ed25519 key as raw public key client cert — the server-side extraction
already works); key-type-aware server cert verification (raw key =
fingerprint match, X.509 = CA verification via WebPkiServerVerifier —
AcceptAnyServerCertVerifier is only safe for raw keys); fingerprint
normalization. The iroh path already works (RFC 7250 raw keys, both sides
exchange automatically); the gap was quinn-only.

Dissolve OQ-35: the 'API key asymmetry' framing was wrong. PeerEntry
supports multiple credential paths; ApiKeyEntry is for tokens that ARE the
identity.

Add OQ-37: X.509 outgoing-only case — the three auth types and how X.509
server identity fits the peer model. Not blocking the ADR-029 migration;
downstream (HTTP crate phase).

Update auth.md, config.md, client-and-adapters.md, call/README.md,
core/README.md, open-questions.md, README.md, and call_client.rs source
comment.

glm-5.2 1d94aaea51 docs(arch): resolve call-crate OQs, promote OQ-29 to load-bearing on ADR-030
Resolve the call-crate open questions where the decision is made —
OQ-27 (auto-re-import), OQ-28 (same-peer collision = error), OQ-30
(PeerRef::Any insertion-order first-match), OQ-31 (services/list-peers
opt-in). These were previously marked 'open' with 'v1' hedging language
despite having a decided default. What remains (refresh(), richer routing,
services/list-peers the op) is genuine feature addition, not unmade
architecture.

Reframe OQ-32 (multi-hop) as a feature extension rather than a 'v1'
deferral — the one-hop model is the architectural commitment; extending
to multi-hop doesn't break downstream.

Promote OQ-29 (CallClient TLS client-auth) from medium to high priority
and surface its real interaction with ADR-030. Previously framed as
'additive — two-way-door remainder,' but ADR-030's PeerEntry fingerprint
→ peer_id resolution requires the client to present a TLS client cert.
With with_no_client_auth(), no fingerprint is extracted, the PeerEntry
path is dormant, and PeerCompositeEnv keys on None or the API-key prefix
instead of the stable peer_id. This is the activation path for ADR-030's
primary use case, not an additive feature. Three options laid out: (a)
wire client-auth with the ADR-029 migration, (b) ship token-only and
switch later (the 'compounds into a mess' path), (c) extend PeerEntry
to cover auth_token-based identity. Requires a decision before the
migration lands.

Clarify OQ-36 (concrete adapter shapes): the trait shapes and in-memory
adapters ship with core — the deferral is only for the persistence
adapters (SQLite, etc.). The in-memory adapters are real implementations
of a full repo pattern, not stubs.

Update call_client.rs source comment to reference OQ-29 instead of the
'v1' / 'two-way-door remainder' framing.

glm-5.2 f224ea998c docs(arch): ADR-030..033 — repo/adapter pattern, PeerEntry, CredentialStore, forwarded-for
Land the storage and auth strategy research (findings.md) as four
accepted ADRs and amend the core and call specs to match:

- ADR-030: PeerEntry and Identity.id decoupling. Replaces
  authorized_fingerprints with peers: Vec<PeerEntry>; Identity.id becomes
  the stable peer_id, decoupled from the rotating fingerprint. Supersedes
  ADR-029 Assumption 1's UUID source (one-way door preserved, source
  changes). Resolves OQ-33 and the storage-boundary half of OQ-34. Records
  the API-key asymmetry as deliberate (OQ-35).

- ADR-031: CredentialStore repo trait + InMemoryCredentialStore default
  adapter in core. Second repo trait alongside IdentityProvider. Vault
  encrypts; the store persists the EncryptedData blob; assembly layer
  loads into Capabilities. EncryptedData core mirror includes salt for
  wire-format compat.

- ADR-032: Forwarded-for identity. forwarded_for field on call.requested
  and OperationContext — metadata only, never read by AccessControl::check
  (enforced structurally via the check signature). The from_call handler
  populates it. Wire-format one-way door, folded into the ADR-029
  migration window.

- ADR-033: Storage boundary and repo/adapter pattern. Core defines repo
  traits + in-memory defaults; persistence adapters are separate crates;
  assembly layer wires. Resolves OQ-34. Concrete adapter shapes deferred
  for exploration (OQ-36).

Amends auth.md, config.md, operation-registry.md, client-and-adapters.md,
open-questions.md, README.md, crates/core/README.md. Marks ADR-029

glm-5.2 99c6dd9483 docs(arch): resolve OQ-26 (AdapterError variants) + OQ-33 (PeerId = logical id) + OQ-34 (persistent peer registry)
OQ-26 (resolved): AdapterError variants decided — DiscoveryFailed,
SchemaParse, Transport, Unauthorized, SamePeerCollision (replaces flat
Conflict per ADR-029 §5). #[non_exhaustive] for downstream extension.
Two-way door; the initial set is the code's return type.

OQ-33 (resolved): PeerId is a logical identifier, NOT Identity.id. The
research's v1 default (PeerId = fingerprint) is overridden: coupling PeerId
to crypto material breaks every in-flight PeerRef::Specific and every ACL
entry on key rotation. v1 source is a connection-assigned UUID — a
no-storage workaround that works for the immediate use case (head→workers,
reconnect produces fresh PeerRef, in-flight gets NOT_FOUND which is correct).
The one-way door: PeerId is logical, not crypto — this determines
PeerCompositeEnv key type and PeerRef::Specific payload. The id source
(UUID vs configured name vs peer registry) is the two-way-door remainder.

OQ-34 (new): the storage dimension OQ-33 surfaced. The core crates are
deliberately DB-free (smaller, fewer deps, simpler testing) — this served
local-only state (vault, registry) well, but peer identity is the first
cross-node state that wants persistence. The real solution (a persistent
peer registry mapping stable logical name → current crypto material,
surviving key rotation) is not a v1 blocker (UUID works), but tracked so the
no-DB posture's limit is deliberate, not accidental. The storage boundary
(core gets a PeerRegistry trait vs stays storage-free) is the one-way door;
the backend choice is two-way. Key-rotation/ACL note: decoupling PeerId from
crypto keeps the door open for ACL entries that persist across key rotation
— when the peer registry is built, ACLs key on the logical name and key
rotation becomes vault-only with no remote-side ACL update.

glm-5.2 77eb35a8a5 docs(arch): ADR-029 peer-graph routing model — supersedes ADR-028
ADR-028's remote_safe/trusted_peer was a parallel, weaker authorization system
that duplicated the existing AccessControl/Identity machinery and couldn't
express the head→N-workers pattern (the primary use case). The flat-namespace
single-peer overlay model (one connection layer in CompositeOperationEnv)
structurally breaks the moment a head has two workers both exposing
/container/exec.

ADR-029 replaces it with:
- Peer-keyed overlays: PeerCompositeEnv { connections: HashMap<PeerId, ...> }
  replaces CompositeOperationEnv's singular connection layer. A head node
  routes invoke_peer() to the right peer via PeerRef::Specific / PeerRef::Any.
- AccessControl-based peer authorization: the existing AccessControl::check
  (peer_identity) gates peer calls — the same mechanism that gates every other
  call. remote_safe/trusted_peer/RemoteFilter/list_operations_peer_scoped/
  services_list_handler_peer_scoped are retired. The op's AccessControl IS the
  peer-authorization policy; no parallel system.
- ScopedPeerEnv: peer-qualified reachability (peer-pinned allowlist) replaces
  from_call's namespace_prefix as the disambiguation mechanism. Cross-peer
  collision dissolves (separate sub-overlays); same-peer collision stays error.
- services/list-peers opt-in for peer-attributed re-export listing.

POC-validated against real types (scratch module written, type-checked,
removed; build clean, 207 tests pass). Petgraph not needed for v1 (one-hop,
shallow); nested HashMap suffices; extends to multi-hop without redesign (OQ-32).

OQ impact: OQ-25 dissolved (no marking); OQ-28 cross-peer dissolved / same-peer
stays; OQ-26/27/29 stay; new OQ-30 (Any routing policy), OQ-31 (list-peers
semantics), OQ-32 (multi-hop federation).

Research: docs/research/alknet-call-peer-routing/findings.md (POC shapes,
prior art — Ray.io actors, Dapr service invocation, full ADR draft).
ADR-028 marked Superseded; ADR-017 DC-1 amendment updated to point at ADR-029.

glm-5.2 f9c0ab092b docs(arch): sync call-completion specs with implementation — Dispatcher/RemoteFilter, ClientError, OQ-29
Post-implementation spec sync after the call-completion batch landed
(commits e4a2594..a3825f5). The sub-agent review flagged no spec drift, but
comparing the implemented types against the spec sketches surfaced five
details the specs didn't name — filled in here so the spec matches what was
built:

- client-and-adapters.md: name the shared Dispatcher (protocol/dispatch.rs)
  + RemoteFilter mechanism that enforces ADR-028's default-deny at dispatch
  time (the load-bearing security gate — checks remote_safe before building
  context, before any capability material reaches the handler). Add
  ClientError/RemoteIdentity types, the spawn_dispatch lower-level API, and
  the services_list_handler_peer_scoped wiring (the assembly layer must
  register the peer-scoped services/list handler for a CallClient's registry,
  not the plain one). Record the v1 TLS client-auth gap (AcceptAnyServerCertVerifier,
  with_no_client_auth) as OQ-29.
- call-protocol.md: point the adapter dispatch-loop description at the shared
  Dispatcher (dispatch.rs) so readers find the mechanism ADR-017 §1 commits to.
- open-questions.md: OQ-29 — CallClient TLS client-auth + remote-identity
  verification is a two-way-door remainder; the no-env-vars invariant is
  unaffected (auth_token flows via call-protocol payload, not TLS).
- READMEs: current-state now reflects completion done + reviewed (207 lib +
  2 integration tests); OQ-29 added to both OQ summaries.

glm-5.2 2649e068e5 docs(arch): call-completion — ADR-028 peer-scoped filtering + client-and-adapters spec + tasks
Resolves the four gap-analysis decisions (DC-1..4) blocking the alknet-call
client/adapter surface specced in ADR-017:

- ADR-028 (new): locks the one-way door for DC-1 — CallClient registry is
  default-deny (remote_safe: bool on HandlerRegistration, default false across
  all provenance); share-global is an explicit trusted-peer opt-in; filtering
  is a dispatch-time read over the single Layer-0 registry, not a copy.
- client-and-adapters.md (new spec): operationally fills the gap ADR-017 left
  to implementation — CallClient, from_call, from_jsonschema, OperationAdapter
  trait, adapter location map, no-env-vars invariant, exchange-of-operations
  pattern. Keeps call-protocol.md and operation-registry.md under the
  700-line split threshold.
- ADR-017 amended: records DC-2/3/4 v1 defaults (auto-on-reconnect,
  error-on-collision, Result error type) and points DC-1 at ADR-028.
- OQ-25..28 (new): two-way-door remainders (remote_safe shape, AdapterError
  variants, re-import trigger, namespace collision) with v1 defaults recorded.
- Index/cross-ref updates across READMEs and the two existing call specs.

Tasks: 6 task files under tasks/call/ decomposing the completion work along
the gap-analysis priority order — remote-safe-marking (one-way door, first)
→ call-client (phase-risk) → from-call → operation-adapter-trait →
from-jsonschema (parallel with call-client) → review-completion. Graph
validated with taskgraph; parallelism designed in (from-jsonschema runs
concurrent with call-client/from-call once the trait lands).
