- ServeConfig gains cfg-gated SessionSeam / GitSeam Option fields
(whole-Option struct per seam — the shape decision recorded in the
task notes): unset → the owned rows decline even though the feature
is on, no construction-time validation
- SessionSeam carries the alktty backends map + backend selector +
ownership provider; GitSeam carries the alkgit backend quartet +
caller-owned pipeline semaphore + push_options_negotiated
- optional deps alktty 0.8.1 / alkgit 0.1.0 wired feature-to-dep
(pins verified against crates.io: licenses, MSRV, shared alkcall
resolution); gix-hash 0.28 as dev-dep only (alkgit does not
re-export ObjectId for the trait doubles)
- per-feature construction/unset-declines/Debug rows in config.rs;
accessors session_seam_configured / git_seam_configured; docs state
what each seam handle carries
Verified: cargo test (per-feature + --all-features), clippy ×2
(-D warnings), fmt, cargo doc --no-deps, cargo tree feature isolation
(git-build: no alktty; session-build: no alkgit), taskgraph validate
- HostKeyPolicy trait: async, dyn-compatible (Arc<dyn> handle, the
alkcall injected-handle pattern) — decide(&self, &PresentedHostKey)
-> bool with host/port/fingerprint as the decision input
- Verdict type pinned to the russh 0.65 check_server_key shape:
bool is the trust decision; decline reasons stay with the policy
(declines are dispositions, not errors). Flagged for the wave-1 gate
- Built-in default RejectAll: fail-closed reject-all (russh's default,
kept); no accept-all option exists in the crate
- async-trait 0.1 added for the dyn-compatible async handle
(alkcall-precedented; tree-deduped). Flagged for the wave-1 gate
- Tests: default rejects; custom verdict honored; both through the dyn
handle; the whole presented context reaches the policy
Verified: cargo test (14), cargo test --all-features, cargo clippy
--all-targets -- -D warnings, cargo fmt --check, taskgraph validate
tokio = "1.54.1" (full features) with its lockfile tree; version pin
and feature set to be revisited with phase 1 architecture (committed
now to reduce working-tree noise)
Phase 0 base for the russh-wrapped SSH adapter (family ADR-003):
- Cargo.toml: single-crate alkssh 0.1.0, MIT OR Apache-2.0, lib only,
publish exclude list matching the sibling-crate policy; deliberately
empty [dependencies] — the russh pin is phase 0 research output
(alknet main's 0.49 is a data point, not the decision). [features]
carries the fail-closed posture as a comment until the capability
feature graph lands with the committed architecture
- src/lib.rs: crate-root doc describing the adapter shape and the
fail-closed feature contract
- LICENSE-MIT / LICENSE-APACHE (alktty's standard texts)
- .gitignore (target/, node_modules/, .worktrees/)
- CHANGELOG.md: Keep a Changelog stub, [Unreleased] initialization
- AGENTS.md: full agent operating instructions — git workflow
(conventional commits, commit-and-push), 13 project conventions
(russh owns the wire, fail-closed capability features, key reuse via
alkvault-backed sources, visible-surface=authorized-surface,
ALPN as one-way door), verification commands, taskgraph
task rules, SDD phase 0 lifecycle status, architecture context
Verification: cargo build/test/clippy --all-targets -D warnings and
cargo fmt --check all pass (lib stub, zero deps)
