- pocs.md: marked complete; corrected the stale 0.5x-era accept-defaults
hypothesis wording (0.64.1: only auth_publickey_offered defaults to
accept), stage D recorded as ran-in-full, completion gate updated with
per-question resolution status
- added client-side scope section: no dedicated POC needed (client API
exercised throughout POC-1/POC-3) + the acceptor-default fact (russh
client accept-and-drop for unhandled forwarded opens is ours to fix)
- new reverse-runner.md: alkminer pattern extraction (concepts only,
never code) — hub-dials-runner surface inventory, both tunnel legs,
the OAI-proxy secret-hygiene shape, and the client-direction lessons
(keepalive defaults, reconnect-restore, acceptor disposition)
- vision.md: scope-question resolution addendum + whitespace typo fix
A conflation in the research set: alkvault's derive-and-custody surface
(derive_ed25519, SLIP-0010 paths) was being sketched as the SSH key
path. Corrected across the docs — held SSH keys (client outgoing keys
and the server's own host key) are bearer-token-class secrets: opaque
bytes the family holds, vault-encrypted at rest, decrypted at use (the
alkhttp ADR-014 posture). No derivation story, no vault-custody
design, and the Signer-injection idea is withdrawn and recorded with
its dismissal rationale.
- auth-bridge.md: client-side gap re-framed as at-rest storage — the
at-rest shape (OpenSSH encoding inside alkvault EncryptedData), the
at-use lifecycle (decrypt-at-dial, one-time decode_secret_key,
zeroized for the dial), the KeySource-like source shape
- pocs.md: POC-2 rewritten to at-rest key handling (formats comparison,
decrypt-at-use lifecycle, locked-vault fail-closed, Signer dismissal)
- vision.md: principle 5 scoped (secret store, not key generator/custodian)
- russh.md: Signer seam noted as not presumed to be the vault shape
- AGENTS.md/CHANGELOG: convention 6 + context updated to match

The phase 0 document set (documented only; no POCs run yet):
- docs/research/vision.md — guiding principles (russh owns the wire,
door-not-backend, fail-closed everything, one seam per mapping,
family identity not SSH identity); non-goals (no sshd, no sftp until
alkfs, no password auth); the five scope questions phase 0/1 must
answer
- docs/research/russh.md — 0.64.1-era inventory: server/client
Handler method tables, Config knobs, keys module (ssh-key re-export,
fingerprint API), the RC-pinned dependency tree (ssh-key, rsa,
pkcs1), MSRV/edition/license posture; alknet-main referenced as a
rough example only, explicitly not decision input
- docs/research/auth-bridge.md — the alkcall mapping: no
resolve_from_signature exists; the actual surface is
IdentityProvider::resolve_from_fingerprint fed by russh-verified key
fingerprints in auth_publickey; auth-method disposition matrix
(only publickey implemented, all defaults overridden); client side
mirrors alkhttp ADR-014 (key sources, not static keys; vault
client-side only); the vault-to-russh-key bridge named as the
missing design piece
- docs/research/mapping-table.md — the spine: channel-type rows with
feature candidates and the verified sibling serve/consume entries
(alktty drive_session, alkgit serve_duplex_resolved, alksocks
serve_socks5_over, alktunnels consumer wrappers + the no-serve-over-
stream absence note); request-level rows; parse-then-route dispatch
inside the session channel; the alk/ssh ALPN topology question
(ADR-004 reserved / ADR-034 stream_types [0,1] / ADR-042 hub never
runs it); alktunnels route choice flagged for ADR
- docs/research/pocs.md — POC-1 (auth bridge + fail-closed declines
against vanilla OpenSSH), POC-2 (vault-to-russh key bridge:
PrivateKey extraction vs vault-backed Signer), POC-3 (mapping
bake-off stages A-D: git exec, socks -D, tunnel -L, pty); all
standalone mode; findings docs are the deliverables
Verification: cargo doc --no-deps, cargo fmt --check, cargo test
(docs-only change; lib untouched)
