Reserves ADR 0075 for feature #1531: a foldable simulator (iPhone Duo) streams the panel in use, picking the lit panel at open and following SpringBoard's log across folds, and a stream may change size while it runs, announced by a new meta frame. It narrows ADR 0031's Consequences line that the stream's shape does not change.

Draft, Proposed. The decision text is written during the #1531 spec session; the maintainer accepts it at the session's approval. Evidence: proof of concept #1525.

Full details: Title check

Explanation

The title names the main change: a new ADR (0075) proposing that a foldable simulator streams the panel in use. It matches the changeset, which adds the ADR file and updates the ADR index. The title is short and specific and uses the conventional docs(adr) prefix.

Full details: Description check

Explanation

The description states that the PR reserves ADR 0075 for feature #1531, summarizes the decision (panel selection, log following across folds, size changes announced by a meta frame), and notes that it narrows ADR 0031. This matches the changeset, which adds ADR 0075 and updates the README index and ADR 0031/0052 status lines.

Review findings, round 1 (3831f89)

Spec lens (Opus, ADR-only). Assessment: complete.

• R1 (blocking): §4 turns a tap's fraction into a fraction of the upright picture, which differs from ADR 0052 §4 ("positions stay fractions of the device's native frame", the website says the same). The record's Narrows header and README row name only 0031; they should name 0052 §4 for a two-panel device. The 0x82 orientation on the inner panel is not stated (0052 says it stays portrait).
• R2 (nonblocking): Context and the "end the stream" alternative speak of one size per stream as the contract. Android streams already send a later meta on rotation (src/drivers/android/screen/envelope.ts:30-44), so the claim holds for the iOS capture only.

Review notes

Not blocking, not verified. Each is one reviewer's claim.

• spec: docs/internal/adr/0075-a-foldable-simulator-streams-the-panel-in-use-and-a-stream-may-change-size.md:25 speaks of one size per stream as "the contract", as does the "end the stream" alternative; Android streams already send a later meta on rotation (src/drivers/android/screen/envelope.ts:30-44, src/drivers/android/screen/AGENTS.md:35).

Keep capture and input panel state in sync.

If one helper misses a fold during a log interruption, the capture can show one panel while input sends taps to the other. Specify how the helpers reconcile panel state while preserving the log fallback.
