+Binary: `target/debug/anyr` from this checkout (`0.1.11`)
+Isolated home: `/tmp/anyr-verify-20260903-060715-6103/home` (removed by cleanup)
+Releases: `tests/fixtures/releases.json` via `ANYR_RELEASES_JSON` (offline)

+
+## Results
+
+| Artifact | Exit | Observable |
+| --- | --- | --- |
+| `update.txt` | 0 | `Updating v0.1.11 -> v0.2.0-beta.1 (beta channel)`, `✔ Would update to v0.2.0-beta.1`, `Run anyr to start using the new version.` Fixture mode does not replace the binary. |
+| `check.txt` | 0 | labeled `current:` / `latest:` / `channel: beta` and `update available` |
+| `tty.txt` | 0 | PTY transcript: 10 carriage returns, 6 distinct spinner glyphs (`⠋⠙⠹⠸⠼⠴`), from→to, `beta channel`, success checkmark, restart hint |
+| `frames.txt` | — | binary counts for `tty.txt` (animation proof) |
+
+Complementary suite: `update_prints_from_to_channel_and_success` and `update_spinner_animates_on_tty` passed. Lib tests `spinner::tests::live_spinner_writes_multiple_changing_frames` and `upgrade::tests::updating_line_shows_from_to_and_channel` passed.
+
+No `anyr claude` without `--dry-run`. No paid tokens. No live GitHub Releases.
+
+## Cleanup
+
+`control-anyr cleanup` removed the isolated workdir and left this `artifacts/update-progress/` tree in place.

+# Update progress
+
+`anyr update` shows a ticking spinner with the current → target version and configured channel, then a checkmark success line and a restart hint. The loader must actually move; a frozen `[loading icon]` is a fail.
+
+## Sub-features
+
+- `update-copy` prints `Updating vX -> vY (<channel> channel)` using the running binary version and the selected GitHub channel.
+- `update-success` prints `✔` plus the new version and `Run anyr to start using the new version.`
+- `update-spinner` on a TTY rewrites the status line with changing spinner frames (`\r` plus distinct glyphs).
+- `update-check` keeps the labeled current/latest/channel report and does not install.
+
+## How to get to it (user POV)
+
+- Run `anyr update` to install the latest release for the configured channel.
+- Run `anyr update --beta` or `anyr update --stable` to persist a channel and update it.
+- Run `anyr upgrade` (alias) the same way.
+- Run `anyr update --check` to compare versions without installing.
+
+## Driving it with control-anyr
+
+Preconditions:
+
+- `control-anyr doctor` is clean.
+- Isolated `ANYROUTER_HOME` is in use.
+- Set `ANYR_RELEASES_JSON` to `control-anyr path RELEASES_FIXTURE` so the run stays offline.
+- Do not hit live GitHub Releases.
+
+- **Non-TTY copy.** Export `ANYR_RELEASES_JSON` to the fixture and `ANYR_CHANNEL=beta`. Run `control-anyr cli --out artifacts/update-progress/update.txt -- update`. Exit code `0`. Stdout contains `Updating`, `->`, `beta channel`, a fixture target version (`0.2.0-beta.1`), `✔`, and `Run anyr to start using the new version.` Stdout does not invent model ids.
+- **Check still reports.** Run `control-anyr cli --out artifacts/update-progress/check.txt -- update --check`. Exit code `0`. Stdout contains `current:`, `latest:`, `channel:`, and either `update available` or `up to date`.
+- **TTY spinner ticks.** Export `ANYR_RELEASES_JSON`, `ANYR_CHANNEL=beta`, `ANYR_SPINNER_MS=20`, and `ANYR_SPINNER_MIN_TICKS=6`. Run `control-anyr pty run --timeout 6 --out artifacts/update-progress/tty.txt -- update`. The transcript contains at least two distinct spinner glyphs from `⠋⠙⠹⠸⠼⠴⠦⠧⠇⠏`, a carriage return, `Updating`, `beta channel`, and `Run anyr to start using the new version.`
+- **Proof.** Keep `update.txt`, `update.txt.exit`, and `tty.txt`. Together they show from→to + channel copy and that the loader frames change.
+
+## Gotchas
+
+- Fixture mode does not replace the binary (`ANYR_RELEASES_JSON` is treated as dry-run). Success copy is `Would update to` instead of `Updated to`.
+- `control-anyr cli` is not a TTY, so it will not animate. Use `pty run` for frame-change proof.
+- `ANYR_NO_UPDATE=1` only skips background auto-update. Explicit `anyr update` still runs.
+- Existing coverage lives in `tests/cli.rs` (`update_prints_from_to_channel_and_success`, `update_spinner_animates_on_tty`) and `src/spinner.rs`. Run those as a complement, not as the only user-path proof.
