A photo, sticker or file sent during a running turn waits for the next turn. A line the plugin hasn't taken yet waits until it does. Since 0.10.0 (#40) the 👀 came only when a turn started on the message, so these showed nothing for as long as the running turn took. To the person, it looks like the bot never saw them.

The bot now puts 👀 on a message the moment it receives it, in the update handler, whenever a turn will answer it. That covers private chats and every person's line, sticker, photo or file in the all group. In asked mode it covers a mention, a reply to the bot, a voice note (on the note, never the echo), a photo or file, and an edit that starts or joins a turn. A plain asked line that only goes to the log as context gets nothing.

Every rule from 0.10.0 still holds. The reaction goes out on its own thread, so neither the handler nor the turn waits on Telegram, and a refusal is only logged. The turn-start 👀 does nothing for a message already marked. The end of a turn waits for an arrival 👀 still in flight, so it never lands on top of a reaction-only answer. Taps and bot messages get none, and the bounded memory never forgets a 👀 that is still in flight.

docs/DESIGN.md section 5.2 now says when the 👀 lands.

Tests: 15 new cases in tests/test_eyes.py. I broke each path they cover and watched them fail: no 👀 on arrival (8 fail), the job run inline (1), the end of a turn not waiting on an arrival 👀 (1), 👀 on logged context lines (3), claiming a message twice (24).

The 👀 never stands in for the answer. Four of those cases check that a marked message still gets its own answer: a photo sent mid-turn, a line the plugin never took, a message whose turn failed (on the retry), and one still queued across a restart. Breaking that path (the turn skipping marked lines, a marked line stored as handled, the reaction going only to unmarked messages) fails them.

Summary by CodeRabbit

  • New Features
    • The 👀 reaction now appears as soon as a message the bot will answer arrives, rather than waiting for the bot’s turn to begin. Reactions are applied without delaying message handling or answer generation, and duplicate reactions are avoided.
    • Context-only messages that the bot won’t answer do not receive a 👀 reaction.
  • Documentation
    • Updated the feature description and guidance to reflect when reactions are applied and which messages are marked.

… a running turn never looks unseen (0.10.1)

A message a turn will answer now gets 👀 in the update handler, before it waits for anything: a photo sent during a running turn and a line the plugin has not taken yet no longer show nothing until their own turn. The turn-start 👀 becomes a no-op for a message already marked, and the end of a turn waits for an arrival 👀 still on its way, so it never lands over a reaction-only answer.
A photo sent mid-turn, a line the plugin never took, a message whose turn failed and one queued across a restart all keep their 👀 and still get the answer of their own turn.

Walkthrough

Eligible messages now receive an 👀 request on arrival. The bot tracks pending requests, reuses them during turn handling, and preserves queued messages for later turns when a turn fails or the worker restarts.

Slow reaction requests can delay replies or let a late 👀 replace an answer reaction. These are bounded issues; merging is reasonable with owner awareness and follow-up on ordering and backlog limits.

The raw summary and objectives both describe this arrival-time marking in bot.py, DESIGN.md, README.md, and tests/test_eyes.py. The title also names the version bump to 0.10.1, which matches the version change. Its length (113 characters, 19 words) is long but still a single, specific sentence.

Coordinate edit claims with answer reactions.

If an edit shares a queued arrival claim that exceeds the 10-second wait, unlook can remove the claim when the earlier turn reacts. The job then skips the edit. A later turn can create another claim whose delayed 👀 may overwrite its reaction-only answer.

Leaving this one. It needs a single setMessageReaction call to hang past EYES_WAIT_S (10 s) while an edit of the same message is queued, and the same window already exists in 0.10.0 for a turn-start 👀. The worst case is a 👀 where a reaction-only answer stood, never a lost answer. The job only fires while its own claim is still the current one, so a turn that finishes normally can't be overwritten.

@GeiserX Understood. You accept the risk of a delayed 👀 replacing a reaction-only answer. I won’t press for a change.

## Rules

- In the group the bot reads replies to the bot, answers to its questions, commands, and messages that mention it when Telegram delivers them (as a group admin, all of her messages). Voice notes, photos, videos, stickers and files from her or an admin are always processed. It also answers private chats with her or an admin. With `history_scope: all` the group's other messages go to the assistant as context marked `[not to you]`, never answered. With `answer_scope: all` her and the admins' group texts without a mention start a turn like addressed ones, marked `[no mention]` (her plain texts too when the bot reads the whole group; context stays `[not to you]`, and principle 1 is rendered scoped to allow it); the answer may be only a reaction (on every message of the turn), or no words when the assistant writes `NO_REPLY`, which the bot never sends. A person's group message is never left with nothing: a turn that shows nothing puts 👀 («read») on every message it covered (👍 once where 👀 is refused), and a mention, reply or voice note that got nothing gets `read_no_answer` (a sticker or photo without a mention gets 👀). Bots never start a turn, and a failed turn of only such lines posts no error and no 👀.

Bound the arrival-reaction backlog.

When reactions are slow, each message in an all group adds a job before the pending-line cap applies. In-flight claims cannot be evicted, so _eyed can exceed 1,000 entries. Later answers can wait ten seconds behind queued reactions. Limit the backlog while preserving reaction ordering.

Leaving this one too. The chat is one household group plus private chats, so a thousand reactions in flight at once isn't a load this bot sees. The wait it adds to an answer is capped at EYES_WAIT_S (10 s) by design, and it only happens when Telegram is already slow. Adding a cap on the backlog would mean dropping the 👀 that this change exists to show.

@GeiserX Understood. For the expected household load, you’re accepting the unbounded backlog to preserve arrival reactions.
