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).
W1 (call/protocol/abort-cascade-wiring): wire AbortCascade into
CallAdapter handle_stream for EVENT_ABORTED. Cascades with
AbortPolicy::AbortDependents, aborts root, no descendant frames on
wire (ADR-016 Decision 2). Two integration tests added.
W2 (core/endpoint-client-fingerprint): extract TLS client cert
fingerprint in dispatch_quinn (SHA256:<hex> of leaf cert DER via
peer_identity) and dispatch_iroh (ed25519:<hex> of peer NodeId).
Fingerprint format documented in auth.md. Server config change
(with_no_client_auth → request-but-don't-require) deferred to new
follow-up task core/endpoint-request-client-cert.
W3 (vault/mnemonic-debug-redaction): replace Mnemonic derive(Debug)
with manual redacting impl (phrase: "[REDACTED]"). Seed confirmed
no Debug impl. Redaction test added.
W4 (core/auth-apikey-resources): Option B — drop entry.resources from
spec. External identities (token/fingerprint) grant scopes only;
resource-scoped ACLs are composition-internal (ADR-015/022). auth.md
corrected + limitation documented. Two tests confirm empty resources.
review-post-impl-fixes: all 4 verified, workspace green (326 tests,
0 failures, 0 clippy warnings). Review #004 status → resolved.
Graph: 34 tasks, 12 gens.
W1 (call/protocol/abort-cascade-wiring): wire AbortCascade into CallAdapter
handle_stream for EVENT_ABORTED. W2 (core/endpoint-client-fingerprint):
extract TLS client cert fingerprint in dispatch_quinn/dispatch_iroh.
W3 (vault/mnemonic-debug-redaction): replace Mnemonic derive(Debug) with
redacting impl. W4 (core/auth-apikey-resources, level: research): decide
whether ApiKeyEntry should carry resources, then implement or drop from
spec. review-post-impl-fixes gates on all four. Graph: 33 tasks, 12 gens.
Break down the three initial crates (alknet-vault, alknet-core, alknet-call)
into dependency-ordered task files for implementation agents.
Structure:
- tasks/vault/ (10 tasks) — drift fixes from ADR-025/026 refactor, review,
spec sync. Vault is independent and can run fully in parallel with core/call.
- tasks/core/ (6 tasks) — crate init, core types, config, auth, endpoint,
review. Core is foundational; call depends on it.
- tasks/call/ (12 tasks) — split into registry/ and protocol/ topic subdirs
reflecting the two subsystems. CallAdapter is the merge point.
Key decisions:
- Drifts 3+9+10 grouped as one task (key-versioning-rotation) — the complete
ADR-021 rotation feature that doesn't compile in pieces
- Reviews injected at end of each crate phase (vault, core, call)
- Vault spec-sync task removes the drift table and bumps doc status to stable
- ACME deferred in core/endpoint (noted as TODO; X509 manual certs for now)
- OperationEnv kept as a trait (load-bearing for ADR-024 layering)
Validated: 28 tasks, no cycles, 11 generations of parallel work.
Critical path runs through call (11 tasks). Vault completes by generation 4.
6 high-risk tasks identified (21%): irpc-removal, endpoint, operation-context,
operation-env, call-adapter, abort-cascade.
