Conversation
The session-switch refusal said:
This session belongs to another Runtime host.
Resume it in a new Codewhale process to reopen its saved store.
#6225 reports hitting this from the plainest possible path on a clean install —
start `codewhale`, `/quit`, start `codewhale`, `/resume`, pick the session — and
the advice is impossible to follow, because they *were* in a new process.
Starting a new process and then picking the session from `/resume` returns to
this same switch path. The route that works is opening the session **at launch**:
`TaskManager::start` passes the saved binding through to `open_for_session`,
which calls `validate_existing_store()`, points the runtime at that store and
opens it. That is adoption; the picker inside a running session is not.
So the message was true and unactionable at once. It now names the real
condition and the command, with the session id interpolated so it can be
pasted:
This session's saved Runtime store belongs to a different host. Switching to
it from inside a running session cannot carry that store's queued work
across, but opening it directly can: run `codewhale resume <id>` from your
shell.
This is only the message. The underlying refusal is #6207 and is still wrong
for the case #6225 reports — an existing, ownerless, empty store — but a user
should not have to wait for that to reach their session.
The binding test asserted the old string; it now asserts the refusal points at
the direct-open path and names the session, which is the property that matters
rather than the wording.
Checks: `./scripts/dev-test.sh tui` — 12707 tests run, 12707 passed, 19 skipped.
`./scripts/dev-test.sh tui runtime_store_binding` — 7 passed. CI clippy gate
exits 0; `cargo fmt --check` clean on both files.

Codewhale review
Complete review coverage: 1/1 passes, 2 file patches, sha256:fcbe667c62bafaffbc3ae35f8ef5d60c926519e13471e19e5842aa8a694fa952.
Pass 1: PR #6233 replaces a circular/unactionable session-switch refusal message with one that names the working route (codewhale resume <id>) and interpolates the session id, and loosens the binding test from pinning the old literal to asserting two properties. The message construction (backslash line-continuations, spacing, id interpolation) is correct, and the error type remains String so format! compiles and contains works in the test. The main gaps are that the user-facing promise is not verified anywhere end-to-end, and the new wording still asserts a cause ('belongs to a different host') that the PR itself says is wrong for the case #6225 reports.
Findings
- [WARNING] Message hardcodes an unverified CLI invocation; no test proves it works (
crates/tui/src/tui/ui/apply.rs:3642)
The new message tells users to runcodewhale resume {id}, but nothing here validates that this exact command/binary/flags form is real or that passing the session id (rather than a store id/path) actually adopts the store.session.metadata.idis the session id, and the message is about reopening a saved Runtime store; if the CLI resume subcommand expects a different identifier or invocation, users are sent to a second dead end — the exact failure mode this PR is fixing. Because the test only asserts the substring "codewhale resume", a divergence between the message and the real CLI (wrong flag, wrong binary name, id rejected) would pass CI silently. - [WARNING] Core user-facing claim is untested; only the string is tested (
crates/tui/src/tui/ui/tests/runtime_store_binding.rs:289)
The value of this change is the claim that opening the session at launch adopts the store. The updated test only asserts that the error string contains "codewhale resume" and the session id (runtime_store_binding.rs:288-295); it does not exerciseTaskManager::start->open_for_session/validate_existing_storeto prove adoption succeeds, nor does it pin the full command shape (codewhale resume <id>). A regression that changes the CLI syntax, or that breaks the direct-open path the message now advertises, would leave the message confidently wrong with all tests green. - [INFO] New wording may still misdiagnose the #6225 case (
crates/tui/src/tui/ui/apply.rs:3639)
The message asserts the store "belongs to a different host." The PR description states the underlying refusal (#6207) is still wrong for the case #6225 actually reports — a store that exists, is owned by nobody, and holds nothing. For that user the new message attributes a cause (foreign host) that may not be true, even though the actionable advice is now correct. Consider softening the causal clause (e.g. describing the observable condition rather than the inferred owner) so the message is accurate for both cases. - [INFO] Comment duplicates PR narrative and references internal symbols that can drift (
crates/tui/src/tui/ui/apply.rs:3634)
The 9-line comment (apply.rs:3629-3637) restates the PR description and hardcodes internal names (TaskManager::start,open_for_session,runtime_threads.rs,validate_existing_store,open_inner) plus issue numbers. These are not checked by the compiler, so they will silently go stale as the call path is refactored. A shorter comment describing why the picker differs from launch would carry the intent without the drift risk.
Suggestions
crates/tui/src/tui/ui/tests/runtime_store_binding.rs:289— Keep these substring assertions, but treat them as a message-shape check rather than proof of the advertised route. Add a separate test that actually drives the launch-based adoption path (start the runtime with the saved binding already present, asTaskManager::startdoes, and assert the store is opened/adopted and no switch error is produced). That directly validates the promise the new message makes, which the current string-only assertions cannot. If a launch-route test is expensive here, at minimum add a CLI/integration test thatcodewhale resume <id>(with the exact command text in this message) succeeds against the foreign store. This is a test-infrastructure change, so no literal replacement is provided.
Assessment
Pass 1: Small, low-risk change that is correct as written: the format string's line-continuations produce the intended single-spaced message, the interpolated session.metadata.id is a String so format! and the error type are consistent, and the test's use of contains on String with a &String pattern is valid. The wording is a genuine improvement over the circular advice. The remaining risk is not in the diff's mechanics but in its verification: the newly advertised codewhale resume <id> route is unproven end-to-end and its exact syntax is unpinned by the test, and the message still asserts a cause that the PR acknowledges may not hold for the #6225 scenario. Recommend following up with a launch-path adoption test and, ideally, softening the causal clause.

I had written the same message fix independently before reading this PR, and have dropped my commit — this one is better (full id, copy-pasteable). One thing mine had that this does not, offered as a note rather than a change: The advice is only actionable when the store can actually be adopted. Guarding it is a couple of lines at the same site: let remedy = match binding.validate_existing_store() {
Ok(()) => format!("…run `codewhale resume {}` from your shell.", session.metadata.id),
Err(error) => format!("That store cannot be adopted as it stands: {error:#}"),
};Not a blocker — the common case is a store that validates, which is exactly #6225. Take it or leave it. |
The session-switch refusal told users to do something impossible.
#6225 hits this from the plainest path on a clean install — start
codewhale,/quit, startcodewhale,/resume, pick the session — and the advice cannot be followed, because they were in a new process.Why the advice was circular
Starting a new process and then picking the session from
/resumereturns to this same switch path. The route that actually works is opening the session at launch:TaskManager::start(event_loop.rs:849) passes the saved binding through toopen_for_session, which callsvalidate_existing_store(), points the runtime at that store and opens it. That is adoption. The picker inside a running session is not — it can rebind the conversation but cannot carry a store's durable work across, so it refuses.Both halves were true; neither was actionable.
What this changes
Only the message, which now names the condition and the command, with the session id interpolated so it is copy-pasteable:
This is not a fix for the refusal itself. That is #6207, and it is still wrong for the case #6225 reports — a store that exists, is owned by nobody, and holds nothing. But users should not wait on that to reach their sessions, and
codewhale resume <id>works today on 0.9.13 with no patch.Test
The binding test asserted the old literal string. It now asserts the two properties that matter — the refusal points at the direct-open path, and it names the session — rather than pinning wording:

No-Issue: message-only remediation. This deliberately does not close #6225 — it makes the refusal's advice followable (
codewhale resume <id>) without fixing the refusal itself, which is #6207 and stays open, as the body above states. UsingCloseshere would auto-close a bug that is still reproducible.
