 ## Iterating (auto mode)
 The owner chats back and forth; every message that asks for a change gets a change.

-2. Commit (with the attribution trailer) and **push to the work branch** (`git push -u origin <branch>`). Do this every iteration, so the branch always holds the latest working state. If a PR from the work branch is open, update its title and description in the same iteration (see below).
+2. Commit (with the attribution trailer) and **push to the work branch** (`git push -u origin <branch>`). Do this every iteration, so the branch always holds the latest working state.
 3. Reply briefly: what changed, test result, and the pushed commit's short hash.
 
 ## The work branch is the dev branch
 The work branch named in the session instructions (`claude/...`) is the persistent dev branch. The owner's test environment pulls it and restarts the service, so:
 - **Never rewrite the work branch's history, and never reset the branch after a merge**: no reset to `main`, no rebase, no amend of pushed commits, no force-push. A force-push breaks `git pull` on the test environment. After a merge, leave the branch as it is.
 - If the owner wants a fixed name such as `dev`, they will say so; only push to another branch with their explicit permission.
 
-## Pull requests from the work branch
-An open PR takes in every commit pushed to its branch, so a PR opened for one small change can merge far more under its old title (#35 was titled as a CI tweak and merged 14 review fixes). The merge commit on `main` keeps that title for good.
-- Before each push, check for an open PR from the work branch. If there is one, update its title and description so they cover every commit it now holds, not only the change it was opened for.
-- Never make such a PR mergeable (resolve its conflict, merge `main` into it, enable auto-merge) while its title or description is out of date.
-- To merge: `main` takes only a branch that is up to date with it and green on every CI job. Merge `origin/main` into the work branch (a merge commit, never a rebase), run the tests, push, wait for CI on that head, then merge the PR with a merge commit.

+# Classes
+
+Every class in `bot.py` and `lib/`, by what it is for. A class named in two places (`Telegram`, `Slack`, `Discord`) is
+a network's update reader in its `*_common.py` and a markup dialect in `lib/dialects.py`.
+
+## Networks: updates in, messages out
+| Network | Reader of its updates | Bot that posts | Webhook (push) | Pull client |
+|---|---|---|---|---|
+| Telegram | `Telegram` | `TelegramBot` | `TelegramWebhook` | `TelegramPoll` (long polling) |
+| Slack | `Slack` | `SlackBot` | `SlackWebhook` | `SlackSocket` (Socket Mode) |
+| Discord | `Discord` | `DiscordBot` | `DiscordInteractions` | `DiscordGateway` |
+
+- **Bases:** `inbound.Network` (a reader), `inbound.Webhook`, `transports.Transport` (a bot), `pull.Listener` and
+  `pull.SocketListener` (a pull client; `pull.WebSocket` is its connection, `pull.Closed` raised when the server closes it).
+- **What a reader hands on** (`lib/inbound.py`): `Message`, `Press` (a button pressed), `Suggest` (a slash command's
+  arguments as typed) and `Response` (what the network gets back at once); `Recent` remembers what was taken lately, to
+  drop repeats.
+- **`bot.py`:** `WholeLines` writes each log line whole, whichever threads log at once; `Sent` is a response body that
+  starts some work once the server has sent it.
+
+## Markup and delivery
+- `Dialect` (a `str` of the network's name) with `Telegram`, `Slack` and `Discord`: its markup, link syntax and limits.
+- `delivery.Report` (lines, a chart spec, buttons) and `delivery.Preloader` (charts drawn ahead of presses).
+
+## Commands and buttons
+- `worker.Command` (a row of the command table), `CommandJob` (a command run as a job), `Args` (what a command was
+  given), `Request` (a command being answered), `Slash` (a slash command to register) and `Usage` (raised for arguments a
+  command cannot take).
+- `buttons.Button`; `ChartPress`, `MenuPress` and `PickPress` (a press, read from its data); `Act` (what a picker's
+  press asks for).
+
+## Scheduling
+- `jobs.Scheduler` (runs the jobs) and `Job`; `catalog.Item` (a default job); `when.Schedule` (when a job runs).
+
+## Reports and charts
+- `render.Chart` (a chart spec, drawn later); `render._Canvas` and `_Axes` (what a chart is drawn on).
+- Data a report works from: `movers.Moves`, `trades.Trade`, `yahoo.Line` (a price line) and `markets.Market`.
+
+## Data sources and configuration
+- `sharesight.Portfolio`.
+- `config.Env` (finbot.env, fixed at start), `Settings` (settings.conf, new on each reload) and the private `_Reader`
+  that reads their typed fields.
+
+## Errors
+- **Replies, not failures:** `answer.Answer` (lines to reply with in place of the report) and `answer.Nothing` (nothing
+  to show: said only to a command or a button, never in a job's run). Both are also raised by:
+  - `sharesight.NotSetUp` and `PortfolioNotFound`;
+  - `yahoo.NoData`.
+- **Failures:**
+  - `net.RateLimited` (a 429 and the wait it asks for);
+  - `transports.MaybeSent` (a chart's post timed out: it may have arrived);
+  - `sharesight.Refused` (credentials refused: the token is renewed);
+  - `when.ScheduleError` (a schedule or job that cannot be);
+  - `config.ConfigError` (problems in finbot.env or settings.conf, each naming its file and line).
