What changes

A. The dialog that stays open says why. AssignModal took no error prop, so a refused
Hand a task to a Workflow left the host's sentence in the page-level error whose only copy was
drawn behind the modal's own mask: the dialog stayed open with nothing in it. AssignModal now
takes error and draws it as its single role="alert", between the task cards and the
2 Pick who runs it heading — the same shape #2193/#2202 gave Rename, Delete and Create. The
read-failure slot (wf-assign-fail, tasksError) is unchanged and a refusal does not light it.

B. The page draws no second copy of that sentence. The section-level error && !renaming && !deleting && !creating guard gains !assignOpen, so while the assign dialog holds the refusal the
section draws no .wf-err copy: a live region behind the mask is still read out, and one refusal
would be announced twice. The #2202 comment keeps its wording and now names four dialogs. A refusal
with no dialog open still reports once on the page.

C. Every entry starts clean and closing drops the sentence. The two entries in the issue
(the sidebar row and the Stage's onAssign) plus the host's own back door
__flybot__.openWorkflowAssign clear the previous error when they open the dialog, so a re-opened
dialog never inherits the previous attempt's sentence. confirmAssign also clears it before the
call, so a retry does not show the old answer beside the new one. onClose clears it as well: this
dialog owns its refusal, so closing it leaves nothing on the page for the next open to pick up.

Docs: docs/subsystems/workflow.md extends the #2193/#2202 sentence from three dialogs to four,
names Hand a task to a Workflow, and records that opening the assign dialog clears the previous
refusal and closing it drops the refusal instead of leaving it on the page. Changelog:
changelog.d/2237-assign-dialog-refusal.fixed.md.

Red first

Run on the live base 9b8d7316dd (and identically on 2ec6efbf before the last rebase) with the test file from this branch and the sources at that base
(git checkout HEAD^ -- plugins/workflow/client.js):

$ TZ=UTC node --test plugins/workflow/test/client.test.js
not ok 145 - #2237: a refused assign is announced once, inside the open dialog
  and that one announcement is inside the open dialog, not only behind the mask
  + actual - expected
  + []
  - [ 'That Bot is already in this workflow' ]
ok 146 - #2237: a successful assign closes the dialog and leaves no alert
not ok 147 - #2237: re-opening the assign dialog after a refusal starts clean
  no sentence is left over from the previous attempt
  + actual - expected
  + [ 'That Bot is already in this workflow' ]
  - []
# tests 147
# pass 145
# fail 2

The four questions the issue asks, read against that output:

1. Nothing in the dialog — not ok 145: the dialog's alerts are [] while the host refused.
2. No second copy anywhere — the same test's first assertion, the whole tree carries the refusal exactly once, passes on the base: there is exactly one copy today, and it is the one
   behind the mask. That assertion stays after the fix; only the copy moves into the dialog.
3. Success says nothing — ok 146 is green on the base (the counter-case; the fix must keep it).
4. A re-opened dialog starts clean — not ok 147: the second open inherits the previous
   sentence.

With the fix in place the same file runs # tests 147 / # pass 147 / # fail 0.

Ran

• Red first above on 9b8d7316dd, then TZ=UTC node --test plugins/workflow/test/client.test.js
  → 147/147/0 on the fixed tip.

• In that chain: arch-docs: OK (4 changed file(s)); ok core/ equals ds-bot/ + patches/ds-bot/; ok patches/ds-bot/ is what generate writes (generate is a no-op);
  build-client.mjs --check green; all four packed plugins imported; the changelog.d/ check green.

Not run

• The smoke test: core/index.js and core/src/host/ are untouched.
• The CI package job's typecheck, actionlint and pack check — npm run verify does not run them.
• npm_config_cache was pointed at a workspace directory for this run, because ~/.npm is
  read-only in this sandbox and the plugin lint's npm pack step writes a cache; no other part of
  the suite depends on it.

Verdict: PASS at ee264e2

Ran at this tip:

Red first, as required: with only the source file of this diff swapped back to its base blob 9b8d7316 (2568 vs 2576 lines; test file stays at the tip) the file goes 145/147 — not ok 145 ([] where ['That Bot is already in this workflow'] is expected, i.e. the sentence is behind the mask and not in the open dialog) and not ok 147 (re-opening inherits the previous attempt's sentence). Restoring the tip file puts it back to 147/147/0. The success case (ok 146) is green on the base too, so the fix is not bought by breaking the success path.

Both refusal paths land in the dialog: confirmAssign's Bot branch (:2152) and Workflow branch (:2164) each setError(value.error ?? ''); return without closing, and AssignModal now takes error and draws one role="alert" at :1459 between the task cards and 2 Pick who runs it. The sentence is the host's own value.error, not a generic message. The page-level guard at :2245 adds !assignOpen, so the whole tree carries the refusal exactly once — that assertion was already green on the base and stays, and the read-failure slot (wf-assign-fail / tasksError) is untouched and asserted unlit. Reopen hygiene is covered: :2026, :2238, :2270 clear error when opening, confirmAssign clears it before a retry, and onClose drops it.

One gap, not blocking: the Bot-target refusal branch has no test of its own (the new cases pick the Workflow target); both branches feed the same error state and the same in-dialog alert, so the rendering path is shared — worth a case if that branch ever diverges.

Suite: plugins/workflow at this tip is green — 387/387 excluding host.test.js, which cannot resolve the ds-bot package because the tarball I extracted has no node_modules (ERR_MODULE_NOT_FOUND, environment not code; the diff does not touch host.js). CI's own plugins (workflow) job on this tip is success, which covers it.

Scope: compare 9b8d7316...ee264e26 is one commit ahead, 0 behind, exactly the four stated files — plugins/workflow/client.js +18/−10, plugins/workflow/test/client.test.js +88, docs/subsystems/workflow.md +1/−1, changelog.d/2237-assign-dialog-refusal.fixed.md +1. No drive-by edits, no generated files, no gate files. Tier T2 is correct under .github/agent/risk-rules.json: plugins/** is T2 (highest of the changed paths; tests and changelog are T1, docs T0), no T3 path or diff pattern matches.

Check-runs at this tip: 13 success, the only red is enqueue-guard, whose own reason is no Verifier report names the tip ee264e26de45 — this verdict is that report. It also states the head lives in a fork, so agent-pr is not asked of it. No hold, and the only comment is the author's verdict request at this tip (no stop comment).
