Selecting text in a rendered markdown preview shows a Comment pill;
attaching stores a file-quote context draft carrying the file path, the
selected fragment (not whole lines), the user's comment, and a
best-effort source line range resolved by anchoring the fragment's
first and last lines in the raw content — a partially located fragment
gets no range rather than a misleading one. The fragment stays
highlighted while the comment input is open, using the selection
overlay rects shared with chat quote comments, and the preview's
native selection color now matches chat messages. file-quote flows
through the same context contract: composer chip previews, the message
context card, and the metadata round-trip.
Every user-attached context item (diff/file/plan comments, terminal
selections, browser annotations, PR comments and failed checks, linked
issues/PRs, and new chat-quote comments from the selection menu) is now
sent as its own synthetic text part carrying an openchamberContext
metadata payload. The model-facing text keeps the previous wording; the
timeline reads the metadata back and renders each item as a context card
instead of raw prompt text. Legacy messages still render via the old
text sniffing.
The selection menu gains a Comment option with an inline multiline
input, the quoted fragment stays highlighted while commenting, and on
mobile the input overlays the composer pill by rendering inside the
composer form. Add to chat is renamed Add to input; the menu is
restyled and the mobile Copy tile removed. Terminal drafts move their
terminal id out of the language field (persisted-draft migration v3),
and the dead preview-console source is deleted.
