Renames the written-usage rule into practice across the contract surface:
docs/ (architecture, research, plans, sdd), tasks/ (all 43 task files,
taskgraph validate passes), AGENTS.md, README.md, CHANGELOG.md, and the
.opencode/agents/ prompts. Every replacement is a sense-preserving
rewrite (colons, semicolons, commas, parentheses, sentence splits, varied),
never a mechanical swap; no spaced hyphens were substituted. Enum fields,
frontmatter, tables, wire data, and cited identifiers survive verbatim;
en dashes inside numeric ranges keep their meaning.
Verification: taskgraph validate (43 tasks), repo grep clean (single
exempt hit: the verification command's own search pattern in AGENTS.md),
cargo test, clippy --all-targets -D warnings, fmt --check, doc all green.
- src/client_accept.rs: the ReverseListener handles (ReverseEndpoint
carried; cancel() the wire-honest teardown) returned by the -R listen
rows; the shared cancel paths both the handles and the stateless wire
forms compose into; the confirmed cancel releases the listener count
exactly once; no Drop hides a wire op
- src/client.rs: the SshConnection internals behind the Arc
(ConnectionShared) — the handles' independent cancels compose on the
same stack; the §Lifecycle posture module docs (primitives-not-policy,
OQ-12; the abrupt-drop/clean-close facts, row-pinned)
- rows: drop-handle no-wire-state, handle-cancel + budget release,
cancel-mid-data-leg (tunnel build) + the every-build abrupt-drop row;
existing reverse rows adapted to the handles; the unix cancel rides
the handle flavor
- docs/architecture/client.md: the §Lifecycle primitives landing block;
task file filled
Verification: cargo test (default / session / git / tunnel / all-features)
all green; clippy ×2 -D warnings clean; fmt clean; cargo doc --no-deps clean
Eight implementation tasks + the gate under tasks/implementation/,
folding the wave-3 gate's four booked findings in as dedicated tasks
(the gate's own disposition — wave-4 material, not wave-3 backports).
Hardening set (server-side, independent of the client chain,
scheduled first as cheap remediation):
- w4-git-exit-close: booked item 1 — the git row's status-before-close
by construction (the seam/shape decided + recorded in-task; the
saturated-buffer scenario pinned on the wire)
- w4-channel-not-held-rows: booked item 2 — the guard's wire rows on
git/tty pipe/shell, per build (test-only)
- w4-tty-coverage: booked item 3 — the channel_close-fired cancel
path + the Closed/Break no-exit-chunk rows + the write_all
no-deadline known-limit record
- w4-router-collision: booked item 4 — the ListenRouter
token-collision fail-closed pre-check
Client chain (sequential logistically — one client Handler impl):
- w4-dial: the russh client stack + the connection handle + the
client Handler skeleton at fail-closed defaults, over an in-process
fake-sshd server double
- w4-op-rows: exec/pty, direct-tcpip, git exec over the shared
grammar, the sftp client-side decline — the POC-3 §D.3 mechanics
- w4-reverse-listen: the -R leg — forward requests + the acceptor
registry + late-install (the wave's highest-risk task)
- w4-lifecycle: the OQ-12 primitives (cancellable handles, clean
disconnect, no reconnect policy)
review-wave-4 depends on all eight. The gate's item 5 (upstream asks)
stays booked with its owners — no task. Plan wave-4 section carries
the decomposition record + four flagged interpretations; wave table
status updated.
