Inline comments:
In `@cmux-tui/crates/cmux-tui-iroh/src/broker.rs`:
- Around line 522-532: Update validate_base_url to require or normalize a
trailing slash on non-root URL paths before send_json resolves relative
endpoints, ensuring Url::join preserves configured prefixes such as
/api-gateway. Keep existing scheme, host, user-info, query, and fragment
validation unchanged.
In `@cmux-tui/crates/cmux-tui-iroh/src/grant.rs`:
- Around line 171-174: Update the relay fleet comparison in the grant validation
flow to be order-independent, comparing snapshot.relay_fleet and
installed_relay_fleet as sets or equivalent sorted collections. Preserve the
existing equality requirement and error message while allowing identical relay
memberships in different orders.
- Around line 189-198: Update the local admission check in
verify_server_admission so it does not compare Binding values through PartialEq,
which includes last_seen_at. Compare acceptors[0] and local_acceptor using only
their stable identity fields, while preserving the stale-binding rejection for
genuine identity mismatches.
In `@cmux-tui/crates/cmux-tui-iroh/src/identity.rs`:
- Around line 196-202: Centralize the duplicated safe_token validation: in
cmux-tui/crates/cmux-tui-iroh/src/broker.rs:596-602, retain the helper as
pub(crate); in cmux-tui/crates/cmux-tui-iroh/src/identity.rs:196-202, remove the
local copy and use the shared helper from EndpointMetadata::validate; in
cmux-tui/crates/cmux-tui-iroh/src/grant.rs:258-264, remove the duplicate, import
the broker helper, and use it in GrantPeer::validate and the key-ID check.
In `@cmux-tui/crates/cmux-tui-iroh/src/main.rs`:
- Around line 112-123: Update the EndpointRuntimeConfig construction in
run_server to derive the platform via Platform::current_frontend()? instead of
hardcoding Platform::Linux, preserving the existing error propagation and
ensuring TUI server registration reflects the host platform.
- Around line 87-90: Update the credential persistence step after
BrokerCredential::new in the enrollment flow to wrap store.save_credential
failures with clear recovery guidance that enrollment consumed the provisioning
token and the operator must obtain a new token and retry enrollment. Preserve
the existing error propagation while adding this product-specific context.
In `@cmux-tui/crates/cmux-tui-iroh/src/policy.rs`:
- Around line 22-29: Update PRODUCTION_KEYS and STAGING_KEYS usage in new and
verify to include a pinned next-generation relay-policy key before each
rotation, using a versioned current/next key set or a signed, fail-closed
updatable source. Ensure the active next-generation kid is accepted by verify
while retaining the current key and rejecting unpinned material.
In `@cmux-tui/crates/cmux-tui-iroh/src/probe.rs`:
- Around line 93-95: Add explicit success assertions in the reattach path of
cmux-tui/crates/cmux-tui-iroh/src/probe.rs at lines 93-95 and 96-98: in the
identify flow, ensure identify["ok"] is true before checking the protocol; in
the workspace flow, ensure workspaces["ok"] is true before checking
workspace_present. Use the specified failure messages and preserve the existing
subsequent checks.
- Around line 182-187: Update raw_request to extract the request id, then read
responses in a loop using read_json_line: skip any response containing an event
field, and return only when the response id matches the request id. Preserve
propagation of I/O and parsing errors, and reject or otherwise handle a response
with a nonmatching id rather than returning it.
- Around line 159-180: Bound the response read in request with an explicit
tokio::time::timeout and return a clear error when it expires. Apply the same
deadline handling to the corresponding read in raw_request and the
transport-handshake read in open, preserving normal response parsing and error
propagation when reads complete before the deadline.
In `@cmux-tui/crates/cmux-tui-iroh/src/provider.rs`:
- Around line 547-558: Replace the string-based check in is_closed_stream_error
with a typed end-of-stream error defined in transport.rs. Make read_json_line
return that dedicated error for the closed-stream case, expose or import the
type in provider.rs, and detect it through the existing error chain alongside
the I/O error kinds.
- Around line 328-338: Update the close-machine handling around
fresh_discovery() to stop using unwrap_or(1); propagate discovery failure as a
retryable ProviderErrorCode::Unavailable response, matching the existing
Snapshot and OpenMachine error-response shape, and only return
CloseMachineResult with the authoritative revision when discovery succeeds.
- Around line 481-500: Update handle_transport to create and register the
CancellationToken immediately after consuming the ticket and before
state.runtime.dial, using ticket.connection_id. After send_admission completes,
check the token for cancellation and abort setup if it was cancelled; remove the
later registration so CloseMachine can cancel in-flight dialing and admission.
- Around line 80-85: Update the accept branch in serve so listener.accept()
errors are recorded and terminate the serving loop without propagating via ?.
Preserve the existing successful-accept and connection-limit handling, then
allow serve’s existing cleanup block to cancel connections, remove the socket,
and close the endpoint.
In `@cmux-tui/crates/cmux-tui-iroh/src/server.rs`:
- Around line 65-87: Update cmux-tui/crates/cmux-tui-iroh/src/server.rs lines
65-87 in the connections task to explicitly return the IrohPreAuthAdmission
reservation on handshake and connection-admission timeout paths before logging
or propagating errors. Also update cmux-tui/crates/cmux-tui-iroh/src/server.rs
lines 132-139 in the pre-auth stream admission flow to release the same
reservation on timeout, while preserving normal acquire behavior.
In `@cmux-tui/crates/cmux-tui-iroh/src/transport.rs`:
- Around line 389-407: Update read_json_line to accept an AsyncBufRead and use
read_until(b'\n', ...) while preserving the maximum-byte limit, empty-line
validation, and JSON deserialization behavior. Ensure each connection creates
and retains one BufReader for its entire lifetime, including the provider
control loop and iroh receive path, so bytes following the delimiter remain
buffered for subsequent reads.
- Around line 511-519: Update validate_discovery to compare snapshot.relay_fleet
and relay_urls by membership rather than positional equality: require equal
lengths and verify every relay URL in one collection is contained in the other,
while preserving the existing validation error and all other checks.
In `@scripts/iroh-tui-stage1-demo.sh`:
- Around line 52-55: Update the dirty-worktree check in
scripts/iroh-tui-stage1-demo.sh around build_commit to stop before writing to
EVIDENCE_DIR, or require an explicit non-publishing mode; do not publish
acceptance evidence from modified sources. Regenerate
docs/evidence/iroh-tui-stage1-sol/demo.cast and
docs/evidence/iroh-tui-stage1-sol/transcript.txt from the same clean commit.
- Around line 293-302: The demo.cast generation around the transcript-processing
block fabricates timing and must not be presented as a terminal recording.
Replace this transcript-to-cast conversion with the repository’s actual terminal
recording tool capturing the acceptance command and interaction, or rename the
artifact and update its metadata/documentation to identify it as a rendered
transcript.
- Around line 274-280: Replace the server-ready log comparison in the restart
stability check with queries to cmux-tui-iroh status using the existing
state-root and identity arguments. Capture and compare device, tag,
identity-generation, EndpointID, identity fingerprint, binding ID, and relay
count before and after restart, then record success only when every required
field is unchanged.
In `@scripts/iroh-tui-stage1/container-entrypoint.sh`:
- Around line 53-75: Replace the final exec of cmux-tui-iroh in the entrypoint
with a supervised child launch, preserving the existing server arguments. Keep
the shell alive to forward INT/TERM termination to the server and wait for the
server to exit, while retaining cleanup’s ability to stop and reap session_pid.
- Around line 59-67: Replace the socket polling loop in the container entrypoint
with an explicit readiness mechanism coordinated with the cmux-tui launch near
the existing startup command. Have the session process signal readiness through
a ready file descriptor, callback, or equivalent event, and monitor its exit
status so the entrypoint fails immediately if it exits before signaling
readiness; remove the fixed-attempt sleep loop.

Replace socket polling with an explicit readiness event.

…vidence Compare bindings by stable identity fields instead of derived PartialEq so a broker heartbeat timestamp cannot reject valid admission (grant.rs and the same latent case in transport::validate_discovery). Compare relay fleets as sets. Normalize a path-prefixed broker base URL so Url::join cannot escape it. Read framed JSON through one persistent BufReader per connection with a typed StreamClosed signal instead of message matching. Register the provider cancellation token before dialing and fail CloseMachine closed instead of fabricating revision 1. Break out of serve on accept errors so cleanup runs. Probe reads get deadlines, ok assertions on reattach, and id-correlated responses that skip events. Consolidate safe_token into one crate definition. Enroll failures after token consumption now say to mint a new token, and the server command refuses non-Linux hosts instead of registering a false platform fact. The demo refuses to publish evidence from a dirty tree, compares the full identity tuple across restart via a lock-free status command, and drops the synthetic cast; the container entrypoint supervises both processes so traps run and readiness failures surface immediately.

Reject loopback HTTP for credentialed broker requests.
--broker is passed through BrokerClient::new, which accepts loopback http://localhost|127.0.0.1|::1, and later credential-bearing broker requests attach the bearer and refresh tokens on that connection. A process listening on that loopback port can capture/forward those credentials. Require HTTPS for these broker URLs; keep cleartext loopback support in a test-only client if needed.

Keep read_identity_report strictly load-only.
load_or_create_iroh_secret creates endpoint.key if it is absent. In read_identity_report, key_path.is_file() and the loader are separate, lock-free operations, so a deleted key can make the report print a newly generated endpoint identity instead of failing. Use a load-only helper for this path and return an “identity file not found” error when the key is loaded but absent.

Use CMUX_TUI_PAIR_SCOPE instead of the capability literal.
Registration advertises the literal "cmux.tui.attach", while grant.rs admits a peer only when acceptor.capabilities contains CMUX_TUI_PAIR_SCOPE. The two values must stay identical. If the constant changes, registration keeps publishing the old capability and every admission fails with "grant acceptor lacks the TUI attach capability". Reference the constant here.

Derive the ALPN bytes from the text constant.
CMUX_TUI_ALPN and CMUX_TUI_ALPN_TEXT hold the same value in two independent literals. The transport negotiates the byte form, and grant.rs validates claims.alpn == CMUX_TUI_ALPN_TEXT. If the two literals diverge, a grant issued for one ALPN would be accepted on a connection negotiated with the other. str::as_bytes is usable in const context, so one literal is enough.

Compare only the identity fields of the ready line.
first_ready and second_ready contain relays=<count> in addition to endpoint, identity, and binding (cmux-tui-iroh/src/main.rs Lines 133-139). A relay-policy change between the two starts changes the relay count only, yet this comparison then reports FAIL server identity or binding changed across restart.

set -e makes the empty-token check unreachable.
read returns a non-zero status at end of file. If the token file is empty, or stdin is closed, Line 29 or Line 31 fails and set -eu exits the script immediately. The explicit message at Lines 33-35 never prints, so the operator sees an exit with no reason.
Tolerate the non-zero read status and keep the explicit check.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Replace the 1-second liveness poll with a real process-exit event.
The watcher subshell polls kill -0 every second for both children. This is a wall-clock poll used for lifecycle synchronization, which the coding guidelines prohibit for shell runtime code. It also delays server shutdown by up to one second after the session dies, and it leaks a background subshell that cleanup kills but never reaps.
The runtime image is debian:bookworm-slim, so bash is available. Change the shebang to #!/usr/bin/env bash and wait for whichever child exits first with wait -n. That removes the watcher and the poll.

Replace the polling watcher around session_pid and server_pid with Bash
process-event handling: change the script shebang to use Bash, wait for
whichever child exits first via wait -n, then terminate the remaining server as
currently intended. Remove the sleep/kill -0 loop and watcher cleanup
dependency, while preserving the container shutdown behavior and existing
cleanup flow.
