Subject: [PATCH] renderer: Norris autonomous-mode frames (Phase 3 commit #3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phase 3 commit #3 per docs/PHASE3.md §12. Four new renderer functions
for Norris mode visual feedback.

M.norris_begin(goal)
  Bold cyan banner on Norris entry, with the goal text on a dim
  indented line. Frames the start of the planning loop.

M.norris_step(n, max_n, descr)
  Compact one-line step counter ("─ step 3/16 ─") with optional
  description. Renders before each iteration of the planner.

M.norris_halt(step_n, max_n, reason, action)
  Bold red banner when the destructive-op gate fires. Three
  indented lines: step counter, reason (red), action text
  (truncated at 400 chars, newlines collapsed). The interactive
  proceed/skip/abort prompt is shown after this banner by repl.lua.

M.norris_end(status, reason)
  Closing banner. status ∈ {"done", "aborted", "budget_exhausted",
  "stalled", "broker_error"}. Color cyan on "done", red otherwise.
  Optional reason text on a dim line.

The interactive prompt `[aish:<model> ⚡]>` activation lands in
commit #5 (repl.lua's prompt() function).

Smoke-tested all five frames visually — clean ANSI output, correct
truncation on long action strings, color discrimination on
done/aborted/budget_exhausted.
