Subject: [PATCH 03/14] Fix #1681: re-arm terminal reconnect budget on wake +
 honest give-up banner

Laptop sleep suspends the network stack, so the VS Code terminal adapter's
six-attempt reconnect budget (#936) burns instantly against dead sockets and
every tab lands on a permanent-looking 'unable to reconnect after 6 attempts'
banner while Tower and the detached session are healthy.

- terminal-adapter: track give-up class (transient vs the #936 permanent 4xx
  session-gone) and add onWake(), which reconnects a transiently gave-up or
  still-parked adapter and no-ops a healthy or permanently-gone one. The
  exhausted-budget banner is now worded via a one-shot /health probe:
  'Tower unreachable' vs 'reconnect failed (Tower is up)'.
- terminal-manager: rearmAllOnWake() + an injected /health probe.
- extension: call rearmAllOnWake() unconditionally on the window-focus rising
  edge (the extension host's only wake signal; no DOM online/visibility events).
- tests: signal-driven re-arm, the 4xx-still-gives-up guard, and the banner
  wording split.

Subject: [PATCH 04/14] Fix #1681: guard stale /health probe against a
 permanent give-up (CMAP)

CMAP (codex + claude) flagged a race: renderExhaustedGiveUp only rechecked
gaveUp, so if a wake reconnects while /health is pending and the reconnect then
hits a permanent 4xx, the stale transient probe could paint an exhausted-budget
banner over the 'session no longer exists' state. Replace the gaveUp recheck
with a give-up-generation token bumped on every give-up transition (enter,
success, reconnect); the async banner renders only if the token is unchanged.
Adds a deferred-probe regression test.

+# bugfix-1681 — terminal reconnect budget exhausts during laptop sleep
+
+Issue #1681. VS Code terminal tabs show a permanent `[Codev: Connection lost. unable to
+reconnect after 6 attempts. Click here to reconnect]` after laptop sleep, while Tower + the
+detached shellper session are perfectly healthy. Only the client view dies.
+
+## INVESTIGATE (complete)
+
+### Root cause
+- `apps/vscode/src/terminal-adapter.ts`: `BackoffController({ maxAttempts: 6 })` +
+  `scheduleReconnect()`. After 6 consecutive transient failures, `giveUp()` sets
+  `gaveUp = true` **permanently** — the retry loop stops until a manual reconnect click.
+- Backoff curve is `[1s,2s,4s,8s,16s,30s]` ≈ 61s total. During sleep the network stack is
+  suspended, so each `connect()` fails instantly; the whole budget burns before the machine
+  fully wakes. A transient OS event becomes a permanent-looking failure banner on every tab.
+- The only wake signal wired is `onDidChangeWindowState` focus rising-edge (extension.ts:334),
+  which calls `repaintAllOnRefocus()` — a SIGWINCH-only repaint, gated behind the off-by-default
+  `codev.terminal.repaintOnRefocus`. It **never** re-arms the reconnect budget or reconnects a
+  gave-up adapter.
+
+### #936 constraint (architect brief + issue comment)
+The finite budget + `giveUp` was PIR #936's deliberate fix for a pre-June infinite retry loop
+against stale terminal ids. The 4xx fast give-up (`classifyUpgradeError(...) === 'permanent'` →
+`giveUp('this terminal session no longer exists on Tower')`) MUST stay. A wake re-arm must
+re-arm ONLY the transient give-up class, never "session no longer exists on Tower".
+
+### Wake-signal note
+The issue lists "window focus, online, visibility". The VS Code extension host is Node — there
+is no DOM `online`/`visibilitychange` event (`rg` confirms `onDidChangeWindowState` is the only
+window-state hook). So the trio collapses to the focus rising-edge already wired at
+extension.ts:334. Will note this in the PR.
+
+### Fix shape (scoped, ~70 prod LOC, <300 ceiling)
+1. `terminal-adapter.ts`:
+   - Track give-up class: `transient` (exhausted budget) vs `permanent` (4xx). Reset on
+     `recordSuccess`/`reconnect`.
+   - `onWake()`: no-op when disposed, permanently gave-up, or currently OPEN; otherwise
+     `reconnect()` (which already resets backoff + clears gaveUp + reconnects). This also skips
+     a long parked backoff wait.
+   - Honest banner via one `/health` probe (injected `probeHealth` closure): exhausted path
+     words the banner "Tower unreachable" (probe false) vs "reconnect failed (Tower is up)"
+     (probe true) vs current "unable to reconnect after 6 attempts" (no probe / unknown).
+     Permanent path keeps its existing wording.
+2. `terminal-manager.ts`: `rearmAllOnWake()` iterating managed ptys; inject `probeHealth` via
+   `connectionManager.getClient()?.getHealth()` (returns null on unreachable → clean boolean).
+3. `extension.ts`: call `terminalManager?.rearmAllOnWake()` on the focus rising-edge,
+   **unconditionally** (not behind repaintOnRefocus).
+4. Tests: signal-driven re-arm reconnects a transient give-up; 4xx still gives up AND `onWake`
+   does not resurrect it; banner wording split (Tower up vs unreachable). CI can't run a real
+   sleep — will state what was simulated vs needs physical sleep/wake.
+
+### Out of scope
+apps/web `Terminal.tsx` may have a sleep/wake sibling — architect owns filing that separately;
+I leave it untouched and will note in the PR if I confirm the gap.
+
+## FIX (implemented, committed 13126d3a6)
+
+Changed files:
+- `apps/vscode/src/terminal-adapter.ts`: `giveUpKind` field; `enterGiveUp(kind)` +
+  `renderGiveUpBanner(reason)` + async `renderExhaustedGiveUp()` (replaces old `giveUp`);
+  `onWake()`; constructor gains optional `probeHealth`. `reconnect()`/open-handler reset
+  `giveUpKind`.
+- `apps/vscode/src/terminal-manager.ts`: `rearmAllOnWake()` + `probeTowerHealth()` (via
+  `connectionManager.getClient()?.getHealth()`); inject the probe into the adapter ctor.
+- `apps/vscode/src/extension.ts`: call `rearmAllOnWake()` unconditionally on the focus
+  rising-edge (before the opt-in repaint).
+- `apps/vscode/src/__tests__/terminal-adapter.test.ts`: +7 tests (4 wake re-arm incl. the
+  4xx-permanent guard + parked-backoff + healthy-noop; 3 banner-wording split).
+
+Verification (from worktree):
+- `vitest run terminal-adapter.test.ts` → 37 passed.
+- full `pnpm test:unit` → 1016 passed (83 files).
+- `pnpm check-types` → clean (exit 0) after building codev-types/sdk/artifact-canvas deps.
+- `pnpm lint` → clean.
+- Regression pins the fix: the new tests call `pty.onWake()` (nonexistent pre-fix) and assert
+  the probe-worded banners (new). CI cannot run a real sleep; the tests simulate the burned
+  budget + a wake signal. A physical sleep/wake is still the true end-to-end confirmation — will
+  state this in the PR.
+
+### CMAP impl review (gemini / codex / claude)
+- Gemini: APPROVE, no issues.
+- Codex: COMMENT — real race: `renderExhaustedGiveUp` only rechecked `gaveUp`; a stale
+  `/health` probe could overwrite a permanent 4xx banner that landed on a wake reconnect.
+- Claude: APPROVE — same race (non-blocking) + 3 residuals: (2) no throttle on `rearmAllOnWake`
+  (rapid refocus while Tower down restarts in-flight connects/resets budget), (3) focus is the
+  only wake signal, (4) `rearmAllOnWake`/extension wiring unit-untested → do a real sleep/wake.
+
+Resolution (commit deee898ef):
+- FIXED the race (both reviewers): give-up **generation token** bumped on every give-up
+  transition (enter/success/reconnect); the async banner renders only if the token is unchanged
+  — closes both the permanent-overwrite and the double-transient staleness. +1 deferred-probe
+  regression test (38 adapter tests now, full suite still green, types clean).
+- DOCUMENTED as residuals in the PR body (out of BUGFIX scope, follow-ups): the re-arm throttle
+  (2), the single wake signal (3), and the manual sleep/wake verification (4).
+
+## Fences
+terminal-adapter.ts is mine. Not touching views/tower*.ts, workspace-label.ts, fleet-order.ts,
+attention-format.ts, switch-workspace.ts (pir-1566), or views/builders.ts, terminal-manager
+cycle logic owned by pir-1563 — my terminal-manager edits are additive (`rearmAllOnWake` +
+constructor arg), not to the cycle/focus resolution code.

PR-phase CMAP (codex REQUEST_CHANGES, claude non-blocking):
- Race the /health probe against a 2s cap so a blackholed network can't hold the
  give-up banner for the SDK's full 10s request timeout (claude).
- Guard onWake() until VS Code has open()ed the pty, so a wake landing before
  open() can't leak a socket that open()'s connect() replaces (claude).
- Add source-level wiring guards (this file's established harness pattern) for
  the manager onWake fan-out, the /health-probe injection, and the extension
  focus-handler call, so deleting any wiring point now fails a test (codex).
- Drop a dead 'void pty' in a test (claude nit).

Subject: [PATCH 10/14] Fix #1681: wipe the stale give-up banner on recovery
 (no composer remnant)

Auto-recovery made give-up -> reconnect common, exposing a render glitch: the
red give-up banner is client-injected text the reconnected agent TUI doesn't
know about, so its repaint overwrites only the left of the banner row and
strands the tail ('...k here to reconnect]') on the composer line until the
next keystroke.

The banner ended with a trailing newline and cleared hadReconnectNotice (#1001's
persistent form, chosen before auto-recovery), so a successful reconnect never
wiped it. Make it own the current line (no newline) and track it as a wipeable
notice, so clearReconnectNotice() erases it in place on the next open, before
the replay paints. While the terminal stays dead nothing overwrites it, so it
remains fully visible and clickable. Adds a recovery-render regression test.

Subject: [PATCH 12/14] Fix #1681: minor CMAP round-3 polish (unknown-health
 wording, clear probe timer)

- probeTowerHealth returns null (not false) when there's no client, so the
  banner falls back to neutral attempt-count wording instead of asserting
  'Tower unreachable' for an unconfigured client (claude).
- Clear the 2s probe-race timeout when the probe resolves first, so it doesn't
  outlive the resolved race (claude).
- Widen the injected probe signature to Promise<boolean | null>; add a
  null-probe fallback test and update the source-level sentinel regex.
