row 272: scope unavailable-session waits to the chat area

@@ -309,3 +309,34 @@ This follow-up commit/push is authorized before the round 3 gate by sage-3435.
 No local tests, repo Node, mutants or queue writes ran. Gate remains RED until
 Sage reruns; plugins harness compactions is a separately owned dependency, and
 Mos declined an EXCEPT edit. Scrooge reviews this A/B delta; Sage posts round 3.

+## Round 4 — scoped browser heading waits (mos-1460/1461)
+
+Round 3 gate on 72690cae7: bus 891/0, CLI 941/0, business 231/0; plugins
+had only the allowed exact base red, checked by Mos; webui 390/2. Both reds
+were newly added chat-browser missing-session waits at lines 361 and 437.
+Whole-file rerun reproduced 17/2. No round 3 green acceptance claim.
+
+Diagnosis authorized by sage-3450/3453 and mos-1460: unchanged whole-file run
+17/2, 28.223 s; scratch-only CDP probes showed the route reaching chat.js:176,
+catalog rows A/B without M, and catch receiving session-not-found with status
+404. DOM had first h1 "Control board" (shell), then .chat-area h1 "Thread
+unavailable". Product refusal and painting worked. Evidence retained under
+/mnt/storage/scratch/tmp/hueyP1enyB/ (baseline.tap, probe.tap, probe-catch.tap,
+proposed.diff); scratch probe source removed, tracked tree remained clean.
+
+mos-1461 / sage-3458 authorizes exactly two selector changes: document-wide
+h1 becomes .chat-area h1 in those waits. Expected text, timeout and every
+other line of chat-browser.test.mjs remain byte-identical to 72690cae7.
+This scopes the same assertion to its component; it does not weaken the
+composer/write/draft/recovery checks. No production code changes in round 4.
+
+manifest.r4.txt retains the same 17 paths; SHA256 a47ed1a23fb98c1ffe6cbcc4e7130e5c515387a2c5dc41e5ae1cbf04640d8c1b.
+Only chat-browser.test.mjs hash differs from r3. New local follow-up commit
+is authorized before execution; push and single-file run await Sage CLEAR
+while Gizmoduck owns the slot. Required pass: whole chat-browser.test.mjs,
+19/19 and skipped 0, timeout -k 10 300, TMPDIR from
+mktemp -d /mnt/storage/scratch/tmp/hueyXXXXXX. No round 4 run yet.
+After green, claimant moves row to in-review; Sage posts request and
+Scrooge reviews the exact two-line delta. Full five-suite gate remains Sage's.
