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.
2026-07-04 11:38:23 +00:00
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).
2026-07-02 07:43:01 +00:00
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.
2026-06-30 12:27:00 +00:00
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'

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.

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 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
Accepted (Assumption 1 carries the ADR-030 superseded note). Marks the

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).

glm-5.2 d94d7a132a docs(adr-027): TLS identity redesign — ACME + RawKey decoupling
ADR-027 resolves the architectural gap surfaced when ACME integration
became a concrete target:

1. TlsIdentity::Acme variant — static config data (domains, cache_dir,
   directory, contact) with async AcmeState constructed at endpoint
   setup via two-phase TlsSetup (not stuffed into the Clone-able enum).

2. TlsIdentity::RawKey decoupled from the iroh feature — uses
   Ed25519SecretKey (alknet-core-owned wrapper over ed25519_dalek)
   instead of iroh::SecretKey. Raw-key TLS identity (RFC 7250, the
   default for most alknet nodes) now works in quinn-only builds.
   iroh transport converts via SecretKey::from_bytes.

3. ACME feature-gated behind new acme feature (rustls-acme optional
   dep). Non-ACME builds don't compile it.

4. dispatch_quinn guard for acme-tls/1 challenge connections — TLS-ALPN-01
   is handled at the rustls cert resolver layer during the handshake;
   the guard closes challenge connections gracefully instead of logging
   a misleading "no handler" warning.

Research confirmed QUIC (quinn) handles ACME challenges differently than
TCP (reverse-proxy): quinn gives no ClientHello peek hook, but the
challenge is fully answered at the cert resolution step before the
connection surfaces to the application. No handler registration needed.

Spec updates: config.md, endpoint.md, open-questions.md (OQ-12),
overview.md + README.md (ADR index), ADR-010 (cross-ref).

Tasks: core/rawkey-decouple-from-iroh (gen 1, no deps),
core/acme-integration (gen 2, depends on rawkey). Graph: 36 tasks.

glm-5.2 323ee85d40 docs(vault): remove drift tracking artifacts, bump vault docs to stable
The vault spec-to-implementation sync is complete. Remove the drift
tracking tools that were only needed during sync:

- Remove the Known Source Drift table from vault/README.md
- Remove 'known drift' / 'current source uses X' prose from Security
  Constraints sections in vault/README.md, encryption.md, and service.md.
  The permanent constraint statements (OsRng for IVs, zeroized drop,
  no unwrap, etc.) are preserved.
- Remove the drift paragraph in encryption.md Key Versioning.
- Remove stale 'to be updated per ADR-025' / 'postcard tests to be
  removed' notes in protocol.md References.
- Bump status: draft -> stable in the frontmatter of all vault docs
  (README, mnemonic-derivation, encryption, service, protocol).
- Update architecture/README.md: vault doc status entries to stable,
  Current State paragraph reflects vault implementation complete (no
  'pending ADR-025/026 refactor' language).

glm-5.2 2e34590522 docs(architecture): resolve review #003 — type/API surface completeness
Review #003 found 11 critical, 14 warning, and 6 suggestion findings
after reviews #001 (governance/security) and #002 (cross-document
consistency/two-way-door audit) were resolved. The theme: types and
APIs that were *referenced* but never *defined*, and stale ADR sketches
that didn't match the now-updated spec docs.

Critical fixes (11):

- C1: DerivedKey #[derive(Deserialize)] contradicted the custom
  Deserialize that rejects "[REDACTED]" — dropped the derive, added
  explicit manual Serialize/Deserialize impls (protocol.md).
- C2: encrypt prose said "derived at PATHS::ENCRYPTION" but the
  signature takes key_version — updated to encryption_path_for_version
  (service.md).
- C3: derive_encryption_key returned DerivedKey, derive_encryption_key
  _for_version returned EncryptionKey (same cache) — unified on
  DerivedKey, defined CachedKey (service.md).
- C4: tokio vs std::sync::RwLock contradiction — specified
  std::sync::RwLock, dropped tokio from vault deps (ADR-018, ADR-025,
  service.md).
- C5: Missing drift rows in vault README — added #9 (key_version
  ignored) and #10 (rotate not implemented).
- C6: ADR-022 build_root_context and invoke() sketches omitted
  abort_policy (9 fields vs 10) — added the field to both sketches.
- C7: Capabilities type referenced 20+ times, never defined — added
  struct definition to core-types.md with Clone+Send+Sync, Zeroize,
  sealed builder API, immutability guard.
- C8: SessionOverlaySource on CallAdapter but never defined, crate
  violation (alknet-call can't depend on alknet-agent) — defined the
  trait in alknet-call (call-protocol.md), matching the IdentityProvider
  pattern.
- C9: CompositeOperationEnv dispatch fall-through was "a two-way door"
  — added contains() to OperationEnv trait, made the composite probe
  before dispatching, eliminating the sentinel ambiguity.
- C10: No API for Layer 2 (connection overlay) registration, CallConnection
  undefined — defined CallConnection struct + register_imported() API
  (call-protocol.md).
- C11: with_local signature diverged between two examples (4 args vs 5)
  — added capabilities as the 5th arg, made both examples consistent.

Warning fixes (14):

- W1: invoke_with_policy restructured as required method, invoke gets a
  default impl delegating to it — eliminates duplication across impls.
- W2: CachedKey defined (service.md).
- W3: EncryptionKey constructor/glue specified, added to re-export list.
- W4: Secp256k1ExtendedPrivKey defined, derive_ethereum_key glue shown.
- W5: encryption_path_for_version rejects version < 2 (v1 is TS PBKDF2).
- W6: Wire payload schemas for all event types + ResponseEnvelope →
  EventEnvelope conversion table (call-protocol.md).
- W7: Timeout section — deadline on OperationContext, composed calls
  inherit parent's deadline, CallAdapter::with_timeout().
- W8: Request ID generation spec — UUID v4 for composed calls, wire ID
  vs internal ID relationship for abort cascade.
- W9: unlock_new already-unlocked behavior specified (returns
  AlreadyUnlocked).
- W10: KeyType Serialize/Deserialize justification corrected (stale
  irpc reference removed).
- W11: OperationProvenance and CompositionAuthority defined inline in
  operation-registry.md (were only in ADR-022).
- W12: encrypt/decrypt free functions marked pub(crate), relationship
  to VaultServiceHandle methods stated.
- W13: rotate signature removed from encryption.md (it's a
  VaultServiceHandle method, not a free function).
- W14: CallAdapter::new() + with_session_source() + with_timeout()
  constructors shown.

Suggestion fixes (6): Seed: Clone note, VaultServiceInner invariant,
ExtendedPrivKey accessor signatures, CURRENT_KEY_VERSION location, ADR-018
stale actor text, derivation helpers re-export note.

glm-5.2 cb98f42cd4 docs(architecture): resolve review #002 remaining Tier 4 findings
Add ADR-026 (vault key model — HD derivation) recording the foundational
HD-derivation decision, 74' coin type reservation, SLIP-0010/Ed25519
default, secp256k1 feature-gating, and AES-256-GCM cipher choice. These
were previously inline rationale with no ADR (W9).

Extend ADR-018 with an explicit EncryptedData wire format lock — fields,
encoding, and semantics are frozen; no removal without a format-version
migration (W10).

Resolve the remaining guard clauses and spec decisions:

- W2: Capabilities must be immutable after construction (no interior
  mutability). Makes the Arc vs deep-copy clone semantics genuinely
  two-way.
- W5: Published to_* specs are compatibility contracts — best-effort
  mappings are two-way before first publication, one-way after. Version
  generated specs.
- W6: Salt field clarification — v2 salt is permanently unused; a future
  KDF is a different derivation family, not a version-indexed path; the
  field saves a wire-format change only.
- W7: unlock_new returns Zeroizing<String> — the mnemonic is the root of
  trust and must not linger in freed memory.
- W17: OQ-09 WASM — server-side dispatch door is honestly closed
  (Connection is concrete, tokio-bound), not implicitly preserved.
- W18: OQ-10 git — composability fork (raw smart protocol vs call-protocol
  projection) is a separate decision from ERC721 scope.
- W20: from_openapi must prefix imported error codes (HTTP_404) to avoid
  collision with protocol-level codes (NOT_FOUND). Normative rule, not
  naming convention.
- W21: ScopedOperationEnv field is private — construction via new()/
  empty(), query via allows(). Makes the future subgraph refactor
  non-breaking.
- C13: Connection::set_identity — the endpoint does not read identity()
  after handle() returns (Connection is moved into the spawned task).
  Observability is handler-side logging. Simplest honest answer.
- W1: OperationAdapter trait is async, returns Vec<HandlerRegistration>.
  from_call requires async discovery; ADR-022 changed the return type.
- W11: CompositionAuthority::as_identity() defined — constructs a
  synthetic Identity (label as id, scopes, resources) not resolvable via
  IdentityProvider. Second Identity construction path, acknowledged.
- W14: SecretKey is iroh::SecretKey (Ed25519) — consistent with the
  endpoint's iroh dependency.
- W19: Grandchild abort propagation is inherit-by-default (option a) —
  invoke() with no explicit policy inherits parent's policy. ContinueRunning
  auto-propagates to grandchildren unless explicitly overridden.

glm-5.2 7dda6eec68 docs(architecture): add ADR-025 — vault local-only dispatch, drop irpc
Drops irpc from alknet-vault entirely. The vault's dispatch is now direct
method calls on VaultServiceHandle — no VaultProtocol enum, no
VaultMessage, no VaultServiceActor, no mpsc channel, no Service trait, no
RemoteService trait, no postcard serialization. The vault is local-only by
construction.

The core security argument: irpc made the vault remote-capable by default
(RemoteService generated unless no_rpc is passed). The IrohProtocol handler
forwards all messages without auth. The docs framed 'register an ALPN' as a
server-setup change. This is the default-insecure anti-pattern — security
should be opt-in, not opt-out. ADR-025 inverts the default: local-only is
the only mode, and remote access requires building a separate vault-server
crate (a visible architectural act, not a flag flip).

The actor path was already dead code — service.md said 'prefer
VaultServiceHandle directly — no channel, no serialization.' The actor
existed only to make irpc's Service trait work, which existed only to make
RemoteService work, which was the footgun. VaultServiceHandle's
Arc<RwLock> provides concurrent reads and exclusive writes — better
throughput than the actor's sequential processing.

DerivedKey serialization simplifies: always redact on serialize (for
logging safety), reject '[REDACTED]' on deserialize with an error. No
'postcard preserves bytes' path. This resolves review #002 W8 (silent
corruption on JSON-deserialized DerivedKey).

Resolves:
- OQ-21: remote vault access — resolved (not deferred). Not a vault crate
  feature; if needed, a separate vault-server crate with its own ADR.
- C7: vault-server-crate question decided — not created now, not precluded.
- C8: operation access policy table dissolved — all operations local-only
  by default; if a vault-server crate exposes some remotely, that crate
  defines the policy.
- W8: DerivedKey JSON deserialization — resolved (reject redacted payloads).

Amends ADR-005 (irpc remains for alknet-call, not for alknet-vault),
ADR-018 (vault is even more standalone — zero RPC framework deps),
ADR-019 (vault is the only layer, not just the only direct-caller layer),
ADR-008 (vault integration point unchanged, but now local-only by
construction).

glm-5.2 cdf340bec7 docs(architecture): add ADR-024 — operation registry layering, resolve C6
Diagnoses a conflation in the pre-ADR-024 spec: the OperationRegistry
inherited immutability by analogy from ADR-010's HandlerRegistry (ALPN-level),
but the TLS-config argument that justifies HandlerRegistry immutability does
not apply to the operation registry, which lives behind a single ALPN
(alknet/call). This made from_call (which discovers ops over a live connection
at runtime) structurally incompatible with the blanket immutability claim.

ADR-024 layers the operation registry by trust boundary: curated (Local) ops
are static and immutable — the startup trust boundary is where their
composition authority is granted; session (Session) and imported (FromCall
etc.) ops are dynamic at their respective scopes (per-session, per-connection)
— their trust boundaries are per-scope, not per-startup. The principle:
immutability follows the trust boundary. Immutability is the security control
for composing ops (can escalate privilege); provenance + composition authority
are the controls for non-composing ops (can't escalate).

The OperationEnv trait becomes the integration point (Arc<dyn OperationEnv>),
following the IdentityProvider precedent (ADR-004): the CallAdapter composes
the root OperationContext.env per incoming call from the active layers
(curated base + connection overlay + session overlay). Children inherit the
parent's composite env by Arc::clone — overlay composition happens once at
the root and propagates through the composition tree.

Resolves review #002 C6 (OperationContext.env type identity crisis): the
field is split into scoped_env: ScopedOperationEnv (reachability data, from
the registration bundle) and env: Arc<dyn OperationEnv + Send + Sync>
(dispatch trait object). One field was being used as two different types
(reachability set with .allows() and dispatch trait with .invoke());

Localizes W4 (hot-swap ↔ registry mutability coupling) to the connection
scope: no global mutable registry to hot-swap; overlays replace naturally
with connect/disconnect and session start/end. Schema-drift on reconnect is
a per-connection overlay-rebuild concern, not a global hot-swap protocol.

Partially addresses W3 (CallClient registry security): the registry-shape
sub-question is resolved by the overlay model; the capability-exposure
sub-question (what capabilities a remote peer can trigger) remains for
ADR-017 — ADR-024 does not overclaim resolution there.

Amends OQ-04 to scope its immutability claim to the HandlerRegistry and
cross-reference ADR-024 for the operation registry. Generalizes OQ-19's
session-overlay mechanism to also cover connection-scoped remote imports —
both are per-scope dynamic overlays on the static curated base, using the
same trait-layering mechanism.

glm-5.2 c62a6adc7b docs(architecture): resolve review #002 Tiers 1-3 — mechanical and consistency fixes
Governance (Tier 2):
- Advance ADR-022 and ADR-023 from Proposed to Accepted (specs already
  depend on their types as source of truth)
- Amend ADR-015: mark Decision 3 and Assumption 6 as superseded by ADR-022;
  update handler_identity type to CompositionAuthority
- Amend ADR-002: note handle() signature revised by ADR-007 (BiStream → Connection)
- Amend ADR-004: note 'enrich/replace' AuthContext language superseded by
  ADR-011's immutability model; update to describe set_identity on Connection
- Update main README ADR table to show ADR-022/023 as Accepted

Spec-ADR consistency (Tier 3):
- Add abort_policy: AbortPolicy field to OperationContext struct (ADR-016
  Decision 6 mandated this but the spec omitted it)
- Define AbortPolicy enum (AbortDependents | ContinueRunning) with Default impl
- Add abort_policy to build_root_context and LocalOperationEnv::invoke()
- Define the OperationEnv trait explicitly with invoke() and
  invoke_with_policy() methods (was referenced as 'must remain a trait'
  but never defined)
- Specify From<StreamError> for HandlerError impl with exact variant mapping
- Add Connection::from_quinn() / from_iroh() constructors (was referenced
  as Connection::new() but never defined)
- Remove undefined CertAuthorityEntry placeholder from AuthPolicy v1 (will
  be added additively when alknet-ssh lands)
- Fix config.md key-differences table: rate limits are in DynamicConfig,
  not StaticConfig

Mechanical fixes (Tier 1):
- overview.md: 'closes the QUIC stream' → 'closes the connection' (stale
  from pre-ADR-007 model)
- overview.md: OQ-04 entry updated from stale 'defer to implementation'
  to 'resolved: static at startup'
- mnemonic-derivation.md: remove duplicate helper functions block (incomplete
  first copy, complete second copy)
- ADR-003: add iroh (feature-gated) to alknet-core dependency list, added
  by ADR-010
- ADR-021: fix ambiguous 'W1 drift issue from the vault review' cross-reference
- ADR-022: rephrase FromCall 'leaf locally' to 'leaf in the local registry'
- ADR-017: add error_schemas to from_call mirror list and services/schema
  step (inconsistency with ADR-023)
- ADR-016: fix self-referential citation ('ADR-016 Assumption 5' → 'Assumption 5')
- Add ScopedOperationEnv::empty(), allows(), new() and
  CompositionAuthority::none(), new() impl blocks (referenced but undefined)
- Add call.completed clarification for non-subscription calls
- Add services/schema leading-slash normalization note
- Crate README ADR tables: add missing ADR-013 (call), ADR-015 (core),
  ADR-006 + ADR-010 (vault)
- Vault README: add consolidated 'Known Source Drift' table tracking all
  four drift items (OsRng, unwrap, CURRENT_KEY_VERSION, spawn bug) in one
  place, including the two previously missing from README

glm-5.2 3e238a471b docs(architecture): add ADR-023, resolve OQ-24 — operation error schemas
ADR-023 adds error_schemas to OperationSpec so operations can declare
their domain-level failure modes (FILE_NOT_FOUND, RATE_LIMITED, etc.)
distinct from protocol-level codes (NOT_FOUND, FORBIDDEN, etc.). The
call.error payload gains an optional 'details' field carrying the typed
error payload conforming to the declared schema. from_openapi/to_openapi
map OpenAPI response status codes to/from ErrorDefinitions, making the
adapter contract from ADR-017 faithful on the error axis.

Also fixes W2 (KeyVersionMismatch stale comment in encryption.md —
ADR-021 implements rotation without this variant) and W4
(derive_encryption_key_for_version missing from service.md method list).

Spec updates: operation-registry.md (OperationSpec, ErrorDefinition,
Handler error mapping, services/schema), call-protocol.md (call.error
payload, CallError, ResponseEnvelope), README.md, overview.md,
open-questions.md (OQ-24), call/README.md, encryption.md, service.md.

glm-5.2 1cedc4eeba docs(architecture): add ADR-022, resolve OQ-23 — handler registration, provenance, and composition authority
ADR-022 wires the three controls ADR-015 specified but left without
registration paths (C1-C4 from review #001): composition authority,
scoped env, and capabilities now enter through a HandlerRegistration
bundle. Provenance (Local, FromOpenAPI, FromMCP, FromCall, Session)
determines which ops can compose — leaves don't get composition
authority. CompositionAuthority replaces handler_identity: Identity
(it's a declared authority bundle, not a peer identity). Capabilities
are per-request from the bundle (resolves closure-capture vs context
ambiguity). Kernel/user analogy: user's authority checked at External
gate; handler's composition authority used inside; scoped env bounds
reachability.

Also fixes W1 (stale ADR-020 path example) and W3 (from_mcp missing
from adapter lists in operation-registry.md).

Spec updates: operation-registry.md (OperationRegistry,
HandlerRegistration, OperationContext, OperationEnv, registration
example, capability injection), call-protocol.md (build_root_context),
README.md, overview.md, open-questions.md (OQ-23), call/README.md.

glm-5.2 9087f0579f docs(architecture): document vault remote capability, enrich OQ-21
The VaultProtocol is a remote-capable irpc service by construction —
#[rpc_requests] generates both Service (local) and RemoteService (remote)
trait impls. DerivedKey's dual serialization (JSON redacts, postcard
preserves) was designed for this. Enabling remote vault access is a
server-setup change, not a protocol change.

OQ-21 enriched with full context:
- What's already in place (protocol, serialization, actor, auth transport)
- What's not in place (IrohProtocol handler forwards all messages without
  auth checks; needs NodeId allowlist + message filtering in assembly layer)
- Operation access policy: Unlock/Lock local-only; Derive/Encrypt/Decrypt
  remote-capable
- Use case: machine node → workers (workers don't hold mnemonics)
- Per-machine-node vaults, not shared (compartmentalization)
- Breaking vs non-breaking analysis (enabling = non-breaking; protocol
  evolution = wire break, manageable via ALPN versioning)

The auth-wrapping handler lives in the assembly layer (or a dedicated
vault-server crate depending on both alknet-core and alknet-vault), not in
the vault crate itself — the vault is standalone (ADR-018) and can't
import alknet-core's auth model.

OQ-21 remains deferred — no commitment to implement, but the door is open
and the design space is mapped.

glm-5.2 dc27753680 docs(architecture): add ADR-021, resolve OQ-22 — key rotation via version-indexed paths
Key rotation uses version-indexed derivation paths: each key version maps
to a distinct SLIP-0010 path (m/74'/2'/0'/{version-2}'). v2 is at index 0
(PATHS::ENCRYPTION), v3 at index 1, etc.

Mechanism:
- encryption_path_for_version(version) constructs the path
- decrypt derives the key at the version-indicated path (not always
  PATHS::ENCRYPTION)
- rotate(blob, to_version) decrypts with old key, re-encrypts with new
- No new mnemonic needed — same seed, different path
- Partial rotation is safe — old keys remain derivable
- The vault does not self-rotate; the assembly layer iterates blobs

Source drift flagged:
- decrypt currently ignores key_version for path selection (always uses
  PATHS::ENCRYPTION) — must use version-indexed paths
- rotate method does not exist in source — must be added
- CURRENT_KEY_VERSION must bump from 1 to 2 (per ADR-020, reinforced here)

OQ-22 resolved. Only OQ-21 (remote vault admin, deferred) remains.
2026-06-19 10:09:20 +00:00
glm-5.2 6e9414bc81 docs(architecture): add ADR-020, resolve OQ-20 — HD derivation for encryption keys
The vault uses SLIP-0010 HD derivation from the BIP39 seed for the
AES-256-GCM encryption key, not PBKDF2. This replaces the TypeScript
predecessor's (@alkdev/storage/src/graphs/crypto.ts) PBKDF2-based
approach.

Key decisions:
- HD derivation at m/74'/2'/0'/0' produces the encryption key
- PBKDF2 is not implemented in the vault; no password-based derivation
- salt field is unused in v2 (wire-format compat only)
- key_version=1 reserved for TS PBKDF2 data; key_version=2 for vault HD
- TS-encrypted data requires one-time migration to v2
- CURRENT_KEY_VERSION changes from 1 to 2 (source drift flagged)

OQ-20 resolved: the encryption key derivation method is locked. OQ-22
(key rotation workflow) remains open but does not block implementation.

glm-5.2 dd1ca1de70 docs(architecture): add alknet-vault spec, ADR-018, ADR-019, OQ-20/21/22
Spec the vault crate from its existing implementation. The vault is
stable (implementation exists); this spec documents what IS so the
implementation-sync agent can reconcile source drift.

New spec documents (crates/vault/):
- README.md — crate index, security constraints, public API
- mnemonic-derivation.md — BIP39, SLIP-0010, BIP-0032, derivation paths
- encryption.md — AES-256-GCM, EncryptedData, key versioning, salt
- service.md — VaultServiceHandle lifecycle, actor dispatch, cache
- protocol.md — VaultProtocol irpc messages, DerivedKey redaction

New ADRs:
- ADR-018: Vault as standalone crate (zero alknet deps; own types/errors)
- ADR-019: Vault assembly-layer-only access (CLI is sole caller)

New open questions:
- OQ-20: Salt/KDF Phase B (open, low priority — salt field reserved)
- OQ-21: Remote vault administration (deferred — needs ADR if ever needed)
- OQ-22: Key rotation mechanism (open, low priority — workflow not specced)

Spec-vs-source drift explicitly flagged (for the sync agent):
- rand::random() used for IVs instead of OsRng (security-critical)
- unwrap() on every RwLock acquisition (must use unwrap_or_else)
- ADR-038 / OQ-SVC-03 references in source comments are stale (old numbering)
- VaultServiceActor::spawn returns a non-functional second actor (source bug)
- KeyVersionMismatch error variant is defined but unused in v1

glm-5.2 c0a322ac29 docs(architecture): resolve OQ-11 and OQ-19 — all open questions resolved
OQ-11 (handler-level auth observability): Option B — handlers store
resolved identity on Connection via set_identity. Two identity scopes:
connection-level (observability, write-once-read-many) and per-request
(ACL, on OperationContext). Per-request takes precedence for ACL;
connection-level is for logging/audit only.

OQ-19 (session-scoped registries): Protocol doesn't need changes.
OperationEnv must remain a trait (not concrete) to enable session-overlay
pattern. Three-tier registry: core (static, External+Internal), session
(dynamic, Internal-only), promotion (curated review). Documented as
implementation guard in operation-registry.md.

All 19 open questions are now resolved. No open one-way or two-way doors
remain. The architecture is ready for review and implementation.

glm-5.2 8f19eb8861 docs(architecture): add ADR-017 call protocol client and adapter contract, resolve OQ-15
ADR-017 locks the client/adapter architecture:
- CallClient opens QUIC connections, shares dispatch loop with CallAdapter
- Connection direction independent of call direction (both sides can call)
- from_call adapter: discovers remote ops via services/list + services/schema,
  registers with forwarding handlers (same pattern as from_openapi/from_mcp)
- to_openapi/to_mcp: project local ops to external protocols
- OperationAdapter trait: produces (OperationSpec, Handler) pairs
- Cross-node call tree: abort cascade propagates through from_call handlers
- Credentials from capabilities (ADR-014), adapter ops Internal by default (ADR-015)

The dispatch POC at /workspace/@alkdev/dispatch demonstrated head/worker over
SSH+axum; under the call protocol it's cross-node composition via from_call.
Connection topology (who advertises, who opens) is independent of call
direction — runner pattern, dispatch pattern, and P2P all work.

glm-5.2 e2730869ca docs(architecture): add ADR-016 abort cascade for nested calls, resolve OQ-17
ADR-016 locks the abort cascade model:
- call.aborted cascades to all non-terminal descendants via parent_request_id
- Default policy: abort-dependents (abort everything downstream)
- Opt-in: continue-running (started descendants continue, pending ones abort)
- Server (CallAdapter) discovers descendants and propagates; client sends one abort
- Handlers clean up via Rust async drop semantics (Drop guards)
- parent_indexed map suffices for tree walking; flowgraph is optional prior art

Spec updates:
- call-protocol.md abort cascade section references ADR-016
- OQ-17 resolved, ADR-016 referenced across all call crate specs
- README.md updated: ADRs 001-016, OQ-17 moved to resolved
