Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Design: the transcript window core `src/ui/transcript/transcript_window.zig` is the core. With `FX_TLA_NEXT_TRANSCRIPT_WINDOW=1` the transcript runtime drives it through `src/ui/transcript/transcript_window_shell.zig`; "In fx" below says which of its effects fx runs. The architect questionnaire was skipped at the user's request: the design was worked out with the user directly and is recorded below as decisions D1 to D10. `GOAL.md` holds the criteria, `VISION.md` the positions, and `CONTEXT.md` the current code. ## Decisions - D1: The main screen holds the current compaction cycle as finished blocks plus the live blocks. A finished block is kept as drawn text; the shell owns that text, keyed by the block's sequence number. Tool records are not kept. - D2: The previous cycle stays held after a compaction until the first turn end at which the log holds it. A compaction can land mid-turn while a tool line is still changing. - D3: A settled resize clears the screen and reprints every held block in finish order, at most `Slice` blocks per loop iteration, then repaints the live blocks. - D4: Ctrl+O opens on the newest `Window` blocks from memory, reads older blocks …

How to install
mdr add vercel-labs/fx/tests/tla/transcript_window/design/DESIGN.md@sha256:e0a3406b0182a297The line at the top of this page pins the label git:20261101.9f3d9e8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
