The contextual hint overlay (ADR-0053) opens on F1, but F1 is an escape
sequence the autocast recorder can't emit — so casts (and presenter /
teacher sessions) couldn't trigger the most teaching-relevant overlay.
In demo mode only, Ctrl-G now aliases F1: it runs the same hint logic and
badges AS [F1], so a recording is visually identical to a real F1 press.
Ctrl-G is the only fit — Ctrl+digit (e.g. Ctrl-1) isn't encodable in a
legacy terminal (arrives as a bare `1`), and the kitty protocol that would
encode it needs escape sequences autocast can't send (and the app doesn't
enable keyboard-enhancement flags). Demo-gated, so the shipped keymap
stays F1-only; outside demo mode Ctrl-G is inert.
- app.rs: hint_key guard gains the demo-gated Ctrl-G disjunct;
demo_badge_label maps Ctrl-G -> [F1]; 3 Tier-1 tests + badge assertion.
- ADR-0047 Amendment 1 + README index; also removed two stray
</content> / </invoke> lines accidentally committed in the ADR file.
docs: drop three more stale "deferred" entries from CLAUDE.md — readline
shortcuts (I1b, ADR-0049), tab completion (I3), and syntax highlighting
(I4) are all implemented; only multi-line input (I1) remains open.
Render the keystroke badge and step caption as a solid yellow rectangle
with no border glyphs and a one-cell text margin, instead of a
rounded-border box — deliberately unlike the app's bordered panels so
the demo overlays read as a distinct, eye-catching callout. Shared
fill_overlay_rect helper (borderless Block fill + inset Paragraph).
Snapshots regenerated; ADR-0047 D4 wording updated.
Add `--demo` (and the RDBMS_PLAYGROUND_DEMO env fallback) to enter
demonstration mode, threaded onto App.demo_mode through run_loop —
mirrors the --no-undo plumbing. Off by default, zero footprint when
off. The --help line advertises only the visible keystroke badges;
the Ctrl+] caption trigger is kept low-profile (ADR-0047 D6 updated).
Phase A of ADR-0047; behaviour (badges/captions) lands in B and C.
Accepted decision record for the in-app demo overlay: a --demo mode
that shows automatic keystroke badges ([TAB], [ENTER], …) and a
stealth Ctrl+]-delimited step-caption buffer, both as floating
black-on-yellow boxes at the output panel's bottom-right. All forks
user-confirmed; a /runda pass contributed 10 tightening findings.
