Fixes the empty-composer check for a Claude worker with a background shell. Claude Code then draws ⏵⏵ bypass permissions on · 1 shell without (shift+tab to cycle); claudeModeFooter (internal/orcaterm/screen.go) required the hint, so host delivery would hold every wake to that worker. Same fix as hadron-server#2700, needed before the #1178 cold cutover.

^⏵⏵ \S.*? on(?: \(shift\+tab to cycle\))?(?: · .+)?$: the hint is optional, the mode text must still end in on, one footer row at the bottom, fail closed otherwise.

Closes #1155

Validation

• Red commit a82735f first: ⏵⏵ bypass permissions on · 1 shell, ⏵⏵ auto mode on · 2 shells · ← for agents and ⏵⏵ auto mode on fail ("not judged empty") on main's regex.
• Negatives pinned: unknown ⏵⏵ phrase, bare ⏵⏵, marker plus space, two hintless footer rows (and the existing two-row case).
• go test ./... and make lint pass. Test-and-regex only: no command, JSON, GraphQL or docs surface touched, so no review-changes checklist node applies.

Tier T1 Standard per the gate (BLIND + LOCAL + QA); seats are created at freeze.

BLIND: CHANGES REQUESTED at 4474d2e3a5ee851833bd903894c90b4462992053.

Fresh context-free diff-only run, no tools, repo/project, issue/gate, Hadron/chat or peer artifacts. Verbatim verdict saved/read back before peers: hrn:node:hadronmemory.com:hadron-dev-team-shared:sprints:sprint-2:reviews:hadron-cli-1189:joost.

P2: internal/orcaterm/screen.go:54, mode matcher can consume a later footer segment ending in on (example ⏵⏵ something else entirely · notification on). Restrict the mode portion from crossing segment delimiters and add that negative pin. P3: malformed/truncated cycle-hint and intervening-text rejection cases.

This blind assessment does not establish downstream caller impact from outside the diff. No local tests or stack claimed. Runner Codex/OpenAI, fresh codex exec default model (exact identifier unreported).

QA: PASS at head 4474d2e3a5ee851833bd903894c90b4462992053 (task 01a1887590c177e19d01e07bae64c665).

• vet clean; orcaterm, delivery, team suites ok. The PR's pins fail on main's regex (red-first holds).
• My own 18-row footer corpus all as expected: hintless on · 1 shell (+ ← for agents, PR #435) accepted; off, no on, on!, trailing text, on·1 shell, single ⏵, ⏸, > -prefixed row refused; a half-typed draft stays not-empty.

Limits: mutants dropping the $ anchor, \S or lazy .*? survive the PR's pins (low; anchor unchanged from main; my corpus rows cover it if you want them added); no real Claude Code capture with a background shell; cutover not exercised.

LOCAL APPROVE at assigned4474d2e3a5ee851833bd903894c90b4462992053 — HISTORICAL, HEAD MOVED.

Two-file delta matches gate; no findings. Full tests/lint0issues/orcaterm race PASS. Own3 positive variants retain ghost/visible-draft, nonblank continuation and extra-footer safeguards. Red commita82735f reproduces all3 failures; removing on kills unknown-phrase negative; restored.

Final live read shows new head29911830ea0dd1301538e9931f23eca3043ebb53 with CI queued. This saved review does not cover that delta or count for readiness. Please route the frozen-green delta for its own review/task. No peer artifacts read before save.

Saved/read back: hrn:node:hadronmemory.com:hadron-dev-team-shared:sprints:sprint-2:reviews:hadron-cli-1189:jane-local-4474d2e3. Temporary checkouts cleaned; no actual terminal send/capture, compiled QA, host/cutover/release/install claim.

FIX HEAD 2991183, CI 4/4 green, CLEAN. Folds BLIND P2 (Joost): the mode phrase is now [^·\s][^·]*, so it cannot swallow a later ' · … on' segment; red-first pin ef216ca, plus QA's low (end anchor, \S) pinned: dropping the anchor or the restriction now fails tests. Delta tasks: BLIND Joost, QA Cooper (new); LOCAL Jane's open task should review this head.

BLIND delta: APPROVE at 29911830ea0dd1301538e9931f23eca3043ebb53, delta only from 4474d2e3a5ee851833bd903894c90b4462992053.

Previous P2 closed: mode phrase excludes the segment delimiter, with the reported negative pinned. No new P1/P2 found. Previous P3 partially closed; optional remaining case is unexpected text before a suffix delimiter (⏵⏵ auto mode on trailing · 1 shell). Approval carries to this exact head within the delta-only scope; no automatic later-head carry.

Verbatim output saved/read back before peers: hrn:node:hadronmemory.com:hadron-dev-team-shared:sprints:sprint-2:reviews:hadron-cli-1189:joost-delta-29911830. Fresh context-free run receives only delta and own prior findings, no tools called. Runner Codex/OpenAI default model (exact identifier unreported). Tests inspected, not run; downstream caller implementation outside the diff remains unassessed. No local/QA claim.

LOCAL delta APPROVE — cli#1189
Head: 2991183; actual two-file delta from 4474d2e inspected.

The mode phrase now excludes the middle-dot separator. It cannot consume a later badge ending in ' on'. Independently exercised three negative variants (off mode plus notification on; permissions off plus later auto mode on; unknown mode plus badge on): all refused. My previous hintless-positive / visible-draft / reported-draft / nonblank-box / extra-footer negative probes still PASS. Package tests and go test -race ./internal/orcaterm PASS. New author controls cover a later segment, truncated hint, trailing text and missing mode phrase. No caller or send path changed; prior LOCAL reasoning carries for unchanged code. No new P1/P2/P3.

Live head and CI4/4 SUCCESS verified. Temporary probes removed; detached checkout clean. Disclosure: saw author routing naming the BLIND finding and fix; did not read any peer verdict or PR comment list before saving. This is LOCAL, not BLIND or finder ownership of another seat's P2. Limits: no live terminal/provider, no push/send, no stack, no full-suite/lint/build rerun on this two-file classifier delta. Prior full-suite/lint and caller controls remain historical supporting evidence. Approve exact head only; no release/install/cutover authority claimed.

QA delta: PASS carries at head 29911830ea0dd1301538e9931f23eca3043ebb53 (from 4474d2e; task 01a1887de1ec7229812a4f942a9cd306).

• vet clean; orcaterm, delivery, team suites ok.
• 22-row footer corpus as expected (hinted and hintless footers accepted; foo · bar on, truncated hint, trailing text, on!, off refused; typed draft stays not-empty).
• Mutants all killed by the PR's pins: dropped $, phrase crossing ·, dropped first-char class, hint required. My earlier low gap is closed.

Limits: no real Claude Code capture with a background shell; cutover not exercised. Evidence: https://hadronmemory.com/app/u/hrn:node:hadronmemory.com:hadron-dev-team-shared:sprints:sprint-2:qa:hadron-cli-1189:cooper-qa-delta-29911830

READY for the change manager at 29911830ea0dd1301538e9931f23eca3043ebb53 (hadron-cli#1189, closes #1155).

• Seats at this head: BLIND Joost delta APPROVE, LOCAL Jane delta APPROVE (6502638271), QA Cooper delta PASS (22-row corpus, 4 mutants killed).
• Verified with gh just now: OPEN, not draft, MERGEABLE/CLEAN, CI 4/4 SUCCESS. 4 ahead / 11 behind main with no overlap on internal/orcaterm/screen.go or scratch_captures_test.go.
• Closing keyword: Closes #1155 is intended; the body's opening "Fixes the empty-composer check" has no issue number.
• Scope: the claudeModeFooter regex plus pins only. Not tagged here; no CLI release tag until hadron-server >= 53e12896e is deployed (Eden).
