Post-windowed-tail attribution (findings log 2026-07-03): the blocked- reason complex — two full-tail buildTerminalWaitText builds plus toLowerCase and multi-pattern scans per chunk, existing only to stamp waitBlockedAt — consumed ~85% of onPtyData's remaining cost (~700-790ms/s under an agent-TUI flood). The check now runs at a 50ms cadence over coalesced chunks (PTY chunk boundaries are arbitrary, so coalescing preserves semantics), with a trailing-edge timer so burst-final state is always evaluated, and an immediate bypass when the incoming chunk (plus a 31-char split carry) contains a prompt keyword — so actionable-prompt stamping stays per-chunk-immediate while keyword-free flood frames skip the complex entirely. Previous wait text is cached per pty instead of rebuilt, and state is cleared at both pty teardown sites. 1,415 runtime tests green (including the cross-chunk prompt test, which exercises the keyword bypass), typecheck and lint clean.
