The `.adapt()` overlay button in `SpecDetailView` does a full navigation to `/debug/agent?spec=&library=&language=`. 2. `POST /debug/agent/sessions {spec_id, library, locale}`. The BFF validates the spec and library against `core/constants.py` and the enabled libraries from anyplot-agents `GET /v1/status` (cached), loads a catalogue snapshot through `core/catalogue/queries.py` (title, description, data roles, notes, noqa-stripped code, library version), derives the user id, and forwards it. anyplot-agents normalises the code, runs the readiness scan and the SECURITY validator, and answers `422 not_eligible` for blocked pairs (the 13 map specs, validator failures, files without a `THEME` block or with a non-literal savefig target). anyplot-agents has no database access in phase 1. `GET /debug/agent/eligibility?spec=&library=` gives the button the same answer. `locale` is the browser's locale, recorded with a feedback case; it sets no language, and every session starts in English (see [Session language](#session-language)). 3. `POST .../dataset {text}` runs the deterministic parse and returns a 20-row preview, the `DatasetProfile`, default bindings and warnings. A deterministic pre-filter over every header and cell for text addressed to an AI, then the dataset judge with a data rubric, refuse instruction-like datasets. Both look for injection only: names, postal and e-mail addresses, phone numbers, web addresses and amounts are the user's data and plot like any other value. The judge sees every header and the same five sample rows and five top values the root and the adapter get, with cells in full, in parts of about 4,000 characters, one judge call per part (one part for every eval fixture). When the paste carried notes around the table (`context_lines`, see [Parse](#parse)), they go through the same pre-filter and then, after the dataset judge passed the table, one scope-judge call with the scope rubric, the lines fenced as ``. A pre-filter hit, a verdict other than `in_scope` or no verdict drops every note with a warning and stores the table all the same; no verdict on notes is a strike, because a hidden injection in a copied web table is not the user's doing, and the judge's tokens are booked to the user like the dataset judge's (the `notes_judge` attribution line carries the verdict and the counts, never the text). The route answers the kept notes as `context_lines`, the stored dataset keeps them, and every version that `prepare_data`, `generate_data` or `.to_long()` makes from it carries them on; a new paste replaces them. Judging the notes at the paste rather than in the turn that delivers them keeps every place the root can read them (the summary turn, `get_dataset_profile`) behind one verdict, and lets the data panel show exactly what the assistant got (`# notes sent to the assistant`). No other LLM call happens for a table. Text that is no table the parser can read (prose such as "a bar chart with dog 7, cat 3 and bird 4", a list typed one value per line; at most 4,000 characters, never a JSON array or object, which the parser reads or refuses itself) takes the transcriber path instead (owner rule of 2026-10-11): the pre-filter runs on the raw text, the judge model reads it under the `TranscribedTable` schema (`agents/anyplot/data/transcribe.py`, rubric `prompts/transcriber.md`: keep every value as written, invent and compute nothing, a note on anything ambiguous), the table's CSV is parsed like a paste, and the route answers `transcribed: true` with that CSV, the preview and the note, storing nothing. The page shows the table for the user to confirm or discard, because a wrong reading makes everything after it wrong; confirming posts the CSV through this same route with `confirmed: true`, which skips the free-text fallback (a one-column table would otherwise be read again) and the narrowing to the table (the user has seen every row, so no line is left out as a note or a total), while the deterministic parse, the pre-filter, the judge and the store run as for any paste. -4. The user adjusts the bindings in dropdowns (`PUT .../bindings`), confirms the data with its bindings (`POST .../dataset/confirm`, step 1 of two, see "Two steps: data first, then the plot" below) and clicks **Create plot**, which sends `POST .../messages {action: "create_plot"}`. The server sets the context variable `REQUEST_KIND=action`, so the judge is skipped, and sends a fixed message. Every turn first enters the run queue (see the bounds table below): the stream sends `ready`, then `status{step:"queued", position, waiting}` while the run waits, and the request deadline starts only when the run leaves the queue. +4. The user adjusts the bindings in dropdowns (`PUT .../bindings`), confirms the data with its bindings (`POST .../dataset/confirm`, step 1 of two, see "Two steps: data first, then the plot" below) and clicks **Create plot**, which sends `POST .../messages {action: "create_plot"}`. The server sets the context variable `REQUEST_KIND=action`, so the judge is skipped, and sends a fixed message. Since 2026-10-14 (owner decision: "queue only the pipeline, not every chat message") a turn starts at once: the stream sends `ready` and the root runs. Only the sandbox work waits in the run queue (see the bounds table below): when the root calls `plot_pipeline` (after its readiness check) or `run_data_code`, that call takes the queue's slot and the turn's start in the rate window, the stream sends `status{step:"queued", position, waiting}` while it waits, and the request deadline, paused during the wait, resumes with the time it had left when the slot comes. A plain question, a refusal, `prepare_data` and `generate_data` never wait. So a user sees `ready`, `message`, `done` for a question, and `ready`, `status{queued}` (only when another run holds the slot or the minute's start is spent), `status{adapting}` and the pipeline's steps, `plot`, `message`, `done` for a plot. 5. Root call 1 calls `plot_pipeline({})`. `PipelineArgs` has no spec, library or dataset field; those come from server-set session state, so neither the model nor an injection can redirect the pipeline. Its `theme` (`light` by default) is the one theme the run renders and the reviewer sees; the root sets `dark` only when the user asks for a dark plot, and keeps the latest version's theme, which its session block names, for a change. Without a dataset, with incomplete bindings or without the user's confirmation of the data the pipeline returns `PlotResult(status="not_ready", reason=...)` (`no_dataset`, `incomplete_bindings`, `data_unconfirmed`) before any LLM call. 6. The pipeline streams `adapting`, `checking`, `rendering`, `reviewing` and `repairing` and always ends with `Event(output=PlotResult)`. A `None` output would raise `NodeInterruptedError`. 7. Root call 2 writes a short reply in the session language. The UI fetches the PNG of the rendered theme (with the footer strip), `plot.py` and `data.csv` through the BFF. The light and dark switch calls `POST .../versions/{version}/render {theme}`, which renders the other theme from the version's stored run form (the same code and data) through the render backend and the host gates, with no adapter, no reviewer and no queue, and answers synchronously. @@ -148,7 +149,7 @@ Since 2026-10-14 two more rules hold (the owner's live test of that day): #### Bounds -The owner decided the queue, the rate and the serial renders on 2026-10-09, after spikes S and S2 showed that one instance with 4 GiB serves one sandbox at a time safely. +The owner decided the queue, the rate and the serial renders on 2026-10-09, after spikes S and S2 showed that one instance with 4 GiB serves one sandbox at a time safely.

Since 2026-10-14 a turn takes its entry mid-turn: the `/messages` route runs the ADK invocation in a task of its own and gives the request ledger `run_slot` (`TurnSlot.take` in `agents/main.py`), which `plot_pipeline` and `run_data_code` await before they render or run code; the queue positions it reports go through the stream's outbox while the tool is blocked.

A client that disconnects while it waits leaves the queue, and `POST .../cancel` takes a waiting run out at once and ends the turn. A full queue or an expired wait fails the turn with `capacity` and aborts it, so the root spends no closing call and the page sees the same `error{code:"capacity"}` as before.

The translator tolerates the ADK 2.x `node_info` and `output` fields. A user already over the daily budget gets `ready`, `refusal{code:"budget"}` and `done` without waiting in the queue. Because queued time does not count toward the agents service's deadline, the BFF restarts its own turn budget (`AGENT_REQUEST_TIMEOUT_S`) on every queued status, with the queue's 15 s heartbeat on top because the run may start that long before its first event, and on the first event after the wait. Nothing moves a turn past `AGENT_TURN_MAX_S` (1,190 s), which stays below anyplot-api's `--timeout=1200`: a turn still queued when its run could no longer finish inside that cap ends with `error{code:"capacity"}`, and closing the upstream stream takes it out of the queue before it spends a token. - **Frontend.** A lazy `app/src/pages/AgentChatPage.tsx` at `debug/agent`, laid out as one chat column (since 2026-10-11, "chat first"). The data card (`app/src/sections/agent-chat/DataPanel.tsx`) is the first turn of the thread: a textarea with a 200 KB counter, preview table, binding dropdowns, `.confirm()` at its foot, and the `# changed` block with `.undo()` after the assistant changed the data or computed it from a formula, without `.undo()` when the formula made the session's first data; a formula pasted into the textarea gets the server's `422 formula`, and the card offers `.send()`, which sends the text to the chat as a turn. The assistant's summary of a stored parse is the next turn, and each data change updates the card in place. After `.confirm()` the card collapses into a header pinned under the site's sticky masthead (`✓ data fits · N rows · M columns · version V`), whose `.show()` opens the full card again without leaving step 2; any binding change, undo, data request or new paste drops the confirmation on the server, and the page returns to step 1 with the card open. The header then stays, as `! confirm again · N rows · M columns · version V` with the phrase in bold on a warning-tinted surface, and its `.show()` leads back to the card from anywhere in the thread, for example after a data request sent from below the plot. The thread gets a warning notice that names what dropped the confirmation (`bindings changed`, `the data changed`, `not confirmed on the server`), and the card's step line repeats it next to `.confirm()`; the first binding setup after a paste, where nothing was confirmed yet, gets none. The step line follows the data the card shows: a data request or undo after the loss names the changed data, and a new paste, which nobody has confirmed yet, names no loss. A table read from free text that waits for `.use()` or `.discard()` holds the page in step 1, even when a turn reports the server's confirmation of the stored data. While the header shows, the page's `scroll-padding-top` keeps keyboard focus and scrolled-to content below it. Below the thread sit a progress grid (since 2026-10-12, the owner's variant A: one row per round, `first try`, `repair 1`, ..., the same four steps in the same columns so each step lines up under the round above, and how the round ended on the right, such as `✓ ok`, `✗ review: 3 findings`, `✗ 2 measured`, `✗ code check failed` or, for the shipped round of a `needs_attention` result, `~ 1 finding open` (the round marked `shipped`, which is not always the last: a repair that fails its check leaves the earlier render shipped); the step a round stopped at shows a red ✗ and the steps after it a hollow dot; the facts come from `PlotResult.rounds` and the `outcome` and `findings` that the `repairing` status carries for the round before it; the result card keeps the same grid under `# rounds` and counts `1 repair` instead of `2 attempts`; on a phone the round's label and outcome take a line above its steps), a Stop button (`AbortController` plus the cancel route) and the composer. While a turn without pipeline steps runs (the summary, a question, a data request), the thread shows an in-progress line in the assistant's slot (`summarizing your data …`, `working on your message …`) until the first reply or pipeline step; the progress grid shows only for a plot run, a queue position or pipeline steps, so the two never say the same thing. While anything is in flight, the bindings block says that the bindings and `.confirm()` wait, and a running parse says so under `.parse()`. Once a dataset exists, the composer always shows `.create_plot()`: before the confirmation as the quiet button next to `.send()`, whose click calls nothing and shows a notice under the composer that leads to `.confirm()` (`# confirm the data first · …`, with `.show()`, which scrolls to the button and focuses it; for a table read from text that still waits, it leads to `.use()`). The notice reads the data card at every render, so a table read from text that arrives or is discarded after the click changes its text and the target of its `.show()`. In step 2 it is the filled action: with an empty box it starts the first plot as it is, with text the text goes as the user's turn, so the assistant makes the first plot with that change. Once the library has a plot, the composer refines with `.send()` (a question or a change on the latest version) and keeps a quiet `.start_over()` beside it (since 2026-10-12, `.create_plot()` before: the owner could not tell the two apart), described as "new from the catalogue plot, without your changes": a fresh plot of the same data from the catalogue code. A wide table (since 2026-10-12, `agents/anyplot/data/shape.py`): when the spec wants one required label role and exactly one required numeric role, no numeric series family, and the table holds 2 to 20 numeric columns and no text or boolean column (date columns are kept as keys), the dataset answers carry `suggestion`, the `pivot_longer` into the two role names; the data card shows it as `# wide table` with `.to_long()`, which `POST /v1/sessions/{sid}/dataset/to_long` applies without a model call as the next version with the default bindings for the new columns (undo as usual), and the root's profile tool carries it as `to_long` so the summary names it in one sentence. The chat header carries a language chip next to the library pills (since 2026-10-12): `lang: en`, `lang: de · from data` after a paste set it from the notes around the table or the column names (since 2026-10-14; one `#` notice), `lang: de · detected` after the first typed message set it (the thread then shows one `#` line that names the chip), or `lang: de · chosen`. A click opens a popover with the ten common languages and a field for any other language in Latin letters; a choice calls the language route, and a `done` with `language` updates the chip, never moving it from `chosen` back down to `detected` or `default`. Keyboard focus follows the steps: after the user's own `.confirm()` it moves to `.create_plot()` before the first plot and to the header's `.show()` after it, a turn that reports the confirmation again leaves it where it is, and a key press on a composer button that a run replaces with Stop moves it into the message box, so a second press never stops the run. The **result card** (`app/src/sections/agent-chat/ResultCard.tsx`) reuses the plot page's overlay actions: the rendered plot shown inline as a blob URL, in a box that takes the loaded PNG's own aspect because the footer strip makes it taller than 16:9, with a light and dark switch that renders the other theme on demand through the theme toggle route, **Copy image** (Clipboard API `navigator.clipboard.write([new ClipboardItem({"image/png": blob})])`, falling back to download where unsupported), **Download PNG** for every rendered theme and **Open full size**; the adapted code in `CodeHighlighter` with **Copy code** (`useCopyCode`, one click), **Download plot.py** and **Download data.csv** (the pair runs unchanged); the change list and residual notes; and the quick-feedback control. The card has no composer of its own (since 2026-10-12): a change request or a question about the plot goes through the thread's one composer below it, and the assistant decides whether it is a change or an answer. Earlier versions stay reachable in the thread, each with its own image and code. The same card is reused unchanged when the feature goes public. `app/src/lib/sse.ts` parses the stream over `fetchWithAuth(...).body.getReader()`. The `.adapt()` button is the fourth overlay button in `app/src/sections/spec-detail/SpecDetailView.tsx`, wired through `onUseWithMyData` from `SpecPage.tsx`, and renders only when `CONFIG.features.agentChat && (CONFIG.isDev || adminHint) && eligible`, where `adminHint` is a localStorage flag (`anyplot.adminHint`, `app/src/utils/adminAuth.ts`) that `DebugPage` sets after `/debug/status` succeeds and clears on a refusal, and `eligible` comes from the eligibility route (`app/src/hooks/useAgentEligibility.ts`). It does a full navigation so Cloudflare Access can intercept, and public pages never probe `/api/debug/*`. As built on 2026-10-10: the dataset response lists the spec's roles (`{name, kinds, required, variadic, description}`), so every role gets a dropdown, a variadic family one per member (`y1`, `y2`, ...) plus an empty one for the next, kept contiguous on the client; a refused binding set answers with the check's lines, which the panel lists; the `plot` event carries the stored `version`, which addresses the artifact and theme toggle routes (see [Agent chat](../reference/api.md#agent-chat-admin-only)); the page starts nothing while a turn, a theme render, a parse or a binding change is in flight, since the server would refuse it with `409 run_active`; Stop calls the cancel route and keeps the stream open until the server's `done` (at most 30 s), so a result stored just before the stop still arrives; the session is also deleted on `pagehide` with `keepalive`; a request without a readable answer (in production usually an expired Cloudflare Access session) reloads the page once, then offers a reload link; the queue position shows as a small counter and as a `queued · 2 of 3` line above the progress grid; the button adds `source=plot_page` to the URL, which the page reads for `agent_open` and then drops. `app/scripts/agent-bff-mock.mjs` serves the documented BFF routes and a scripted stream locally (for `scatter-basic` and the series family of `line-multi`), so the page can be driven in a browser without the API, the agents service or a model. - **Analytics** (enum properties only, documented in [Plausible](../reference/plausible.md#agent-chat-admin-only)): the pageview `/debug/agent`, `agent_open{library,source,spec}`, `agent_data_parsed{status,size_bucket}`, `agent_data_confirmed{size_bucket}`, `agent_data_prepared{changes}`, `agent_data_undo{version}`, `agent_plot_rendered{library,status,repaired,spec}`, `agent_guardrail_block{reason}`, `agent_session_saved{include_data}`, `agent_result_feedback{reaction,include_data}`, and `copy_code{page:'agent_chat',method:'agent'}`, all built.
