Merge pull request 'Canvas: make double-click-to-plant work on desktop' (#135) from fix/double-click-focus into main

lastPress sits with the component's other refs and its thresholds at module
scope with the other tuning constants; only a primary-button (or finger)
press counts, like a native dblclick; a press on empty ground clears the
pending half, so bed → ground → bed within 400 ms is not a double-click.

   lives in `commitScope` where no caller can forget it.
 
+- **The assistant's date comes from the client, never from the model.**
+  `POST /agent/chat` carries `today` (the browser's local day, same reason the
+  UI sends `plantedAt`); `Runner.Run` puts it in the system prompt and
+  `NewToolbox` stamps it on every dated tool default through `adapter.day`. A
+  new tool that takes a date defaults through `day()`, not `time.Now()`. Left to
+  guess, the live model dated journal entries a year back (2025) — the year it
+  remembered from training.
+- **`describe_garden` is a summary, not a dump.** Plops are grouped per plant
+  (`service.DescribeGroup`: count, where, planted date, days to maturity) and
+  ids are listed only for groups of ≤ `maxListedPlops`; the first grid-filled
+  garden made the old per-plop describe ~450 entries on every turn. A tool that
+  needs individual ids uses `list_plantings`; bulk work takes (object, plant)
+  — `remove_plantings`, `ClearPlantings`. Don't add a tool that lists plops.
+  With a `year` it is the season view (`GardenFull(year)`: every plop whose
+  time in the ground overlapped the year, pulled ones included, with `removed`
+  / `removedAt` per group) — that is how "what was here last year?" is answered.
+- **The assistant undoes through `undo_change`, never by claiming.** Asked to
+  "undo the beets", the live model once replied "Done!" and changed nothing.
+  `undo_change` wraps `RevertChangeSet(source=agent)`; the prompt still forbids
+  claiming a change no tool made. A revert is its own change set (it points at
+  what it undid), so it never joins the turn's scope — `Run` reports the last
+  revert as the turn's `ChangeSetID` when the turn made no other change, so the
+  reply's "Undo this" is a redo. Keep that fallback: without it an undo-only
+  turn is the one change in the conversation with no undo button.
+- **Outward-facing tools ask first, and refuse without `confirmed=true`.**
+  `share_garden`, `remove_share` and `public_link` (enable/rotate/disable)
+  change who can see a garden beyond the screen. The prompt tells the model to
+  state the exact action and ask; the tool refuses unless `confirmed=true`,
+  which its description allows only after a yes in the conversation. Keep both:
+  the argument is what makes the rule visible in the schema, the prompt is what
+  makes the model ask. Neither is a guarantee, and a new outward-facing tool
+  gets the same pair.
+- **A turn that changed nothing cannot say it did.** `honestReply` in
+  `runtime.go` appends a correction when the reply claims a change ("Done —
+  I've deleted…") and no non-read-only tool call succeeded in the run. Live,
+  glm-5.2 did this twice in one session (a journal entry, then a seed lot:
+  "Done", nothing deleted). The prompt rule stays; the guard is for when the
+  model ignores it. `readOnlyTools` must list every tool that changes nothing
+  — a new read-only tool left out of it makes a turn look like it acted.
+- **Garden notes are the assistant's memory.** `systemPrompt` quotes
+  `Garden.Notes` (owner-written, `%q`) as standing context, and `update_garden`
+  is how the model adds "we're in zone 6a" to them. Notes are replaced whole,
+  so the tool description tells the model to merge; don't add a second store
+  for "things the assistant remembers".
+
+- **Request deadlines are extended through `responseController(c)`, never
+  `http.NewResponseController(c.Writer)`.** A controller built in a handler
+  can't reach the socket — the logging middleware wraps the writer — so every
+  deadline call silently returns `ErrNotSupported`, in production only;
+  `internal/api/deadlines.go` has the mechanism and why `captureController`
+  must stay the first middleware. Corollary for tests: a deadline test must run
+  through `New()`, not `gin.New()` — the #78 fix shipped fully tested on a bare
+  engine and never worked on the live instance.

Fit and focus animate through a CSS transition on the group; drags and zooms don't. Corner handles on the selected object resize it — the one addition to the prototype, since the kinds' fixed default sizes can't make a 2′×8′ bed.

The `majordomo` build tag is gone: a tag that keeps the agent out of the binary only earns its keep if you'd ship a build without it, and the agent is the point. What a day of live use added: the turn carries the gardener's **local day** (`today` in the chat body) into the prompt and every dated tool default, because the model's own idea of the date was a year stale and the server's is UTC; `describe_garden` **groups plops by plant** (count, where, planted date, days to maturity — `DescribeGroup`) and lists ids only for small groups, with `list_plantings` for the rest and `remove_plantings` to act on a whole group; `move_planting` relocates a plop (`MovePlanting`, within or across beds) keeping its planting date; `fill_region` takes an explicit local rectangle and a `seedLotId`; `update_plant`, `read_history` and `copy_garden` (the "<garden> — <year>" plan convention) round out what the model kept reaching for. A mutation on another garden inside a turn is recorded under THAT garden (`record` refuses to file revisions into a scope for a different garden), so undo always finds them where the person is looking. The record-keeping round (2026-08-23): `undo_change` exposes `RevertChangeSet` with `source=agent` — the revert is its own change set, so an undo-only turn reports it as the turn's handle and "Undo this" becomes a redo; `describe_garden` takes a `year` (the season view, pulled plops included, `removed`/`removedAt` per group) with `list_years` beside it, for rotation questions; `update_planting`, `update_journal_entry`/`delete_journal_entry` and `update_garden` correct records in place, and `remove_planting`/`remove_plantings`/`clear_object` take a `removedAt` so a harvest can be backdated; the garden's **notes go into the system prompt** as the gardener's standing facts, and `update_garden` is how the assistant remembers what it is told. Round two added the catalog side — `update_seed_lot`/`delete_seed_lot`, `delete_plant` (refused while anything references the plant), `create_garden` — and `readyAround` on each describe group (planting date + days to maturity, pulled plops excluded), so "what can I pick this week?" is a lookup rather than arithmetic the model gets wrong. Round three is the outward-facing set — `list_shares`, `share_garden`, `remove_share`, `public_link` — gated twice: the prompt says to ask first, and the tools refuse without `confirmed=true`, which the description allows only after a yes in the conversation (a schema-level reminder, not a guarantee — the model could lie, but it has to do so explicitly); plus `delete_planting` for a plop that was never really planted (recorded, so undoable).

+%s
+%s
 
 Conventions you cannot guess and must not assume:
+- Every measurement a tool takes or returns is in CENTIMETERS.
 - Positions in a garden are centimeters from its top-left corner: x grows east, y grows SOUTH.
 - Inside an object (a bed), positions are relative to that object's CENTER, and -y is NORTH.
   So the north half of a bed is negative y. Getting this backwards plants the wrong end.
 - Objects and plantings are version-guarded. Use the version from describe_garden when editing.
+- Dates are YYYY-MM-DD. Tools date what they plant, remove or journal as today unless you pass
+  a date; pass one only when the gardener says it happened on another day.
 
 How to work:
-- Start from describe_garden to see what is actually there. Do not guess ids.
+- Start from describe_garden to see what is actually there. Do not guess ids. It groups each
-- Use find_plant to turn a plant name into an id. If it returns several candidates,
+  bed's plantings by plant, with a count, a rough location and the planting date; a group lists
-  pick the one that matches what the user said, or ask them which they meant.
+  its plops one by one only when it is small. For the ids of a large group use list_plantings,
-- To replant a bed with something else: clear_object, then fill_region with region "all".
+  or act on the whole group at once with remove_plantings.
-- When a tool refuses (for example, the user only has view access to this garden),
+- Use find_plant to turn a plant name into an id. If it returns several candidates, pick the one
-  explain what happened in plain words. Do not retry it.
+  that matches what the user said, or ask them which they meant.
+- To replant a bed with something else: clear_object, then fill_region with region "all". To take
+  one plant out of a mixed bed: remove_plantings. To relocate plants: move_planting, which keeps
+  their planting date — do not remove and replant them.
+- fill_region in grid mode lays out individual plants at true spacing, which is what "so I can
+  plant from it" means; clump mode is a quick sketch. For an area no compass name describes (a
+  middle third, a strip along one edge) give fill_region a rectangle instead of placing plops by hand.
+- A garden named %s is this garden's plan for that year; copy_garden with that name
+  makes one. Never use a different real garden as a scratch space.
+- Past seasons: describe_garden with a year shows what was in each bed that year, pulled plants
+  included; list_years says which years have records. Check it before advising on rotation or
+  answering "what was here last year?" — do not guess from what is growing now.
+- To undo something — yours or anyone's — find the change in read_history and call undo_change
+  with its id. It reverts as a new change that can itself be undone. "Undo the beets" means the
+  change that planted the beets, not pulling them out today; do not re-create what you can
+  revert. A change already marked undone stays undone.
+- To correct a record rather than change the garden — a planting date, a plant count, a journal
+  entry's text or date, the garden's notes, a seed lot — use update_planting, update_journal_entry,
+  update_garden and update_seed_lot instead of removing and re-adding.
+- "What can I pick soon?": each group in describe_garden carries readyAround, its planting date
+  plus the plant's days to maturity. Compare that with today rather than doing the sums yourself;
+  a group without it is a plant the catalog has no days for.
+- A new garden (another place, not a plan) is create_garden; it opens from the gardens list, and
+  this conversation stays with the garden it started in.
+- When the gardener tells you something worth keeping about the place — their zone, usual
+  frost dates, soil, a standing preference — add it to the garden's notes with update_garden
+  (keeping what is already there), and say you did. You will see those notes in every later
+  conversation.
+- Sharing is outward-facing: share_garden, remove_share and turning the public link on, off or
+  over change who can see the garden, beyond this screen. Before any of them, say exactly what
+  you would do — who, which role, or that a link will start or stop working — and ask; do it
+  only when the gardener says yes, and then pass confirmed=true. A message that already says
+  it all ("share this with [email protected] as an editor") still gets the question once.
+- When a tool refuses (for example, the user only has view access to this garden), explain what
+  happened in plain words. Do not retry it.
 
-When you are done, say briefly what you changed — the user is watching the canvas
+How to behave:
-and wants to know what to look at. If you changed nothing, say that too.`,
+- Only claim what a tool actually did. If a tool failed, or there is no tool for what was asked,
-		g.Name, g.ID, g.WidthCM, g.HeightCM, units)
+  say so plainly — never describe a change you did not make, and never say something is undone
+  unless undo_change did it. A tool result that is an error means the thing did not happen: say
+  it failed and why, and what you will try instead. Before you say you deleted, changed or added
+  something, there must be a successful tool result for it in THIS turn — an earlier turn does
+  not count, and neither does meaning to.
+- Every reply of yours that changed the garden has an "Undo this" button under it, and the
+  History panel can revert any change; mention that when it helps.
+- When a request could mean materially different things — "swap the cucumbers and the melons"
+  with two beds of each — say what you would do and ask, rather than clearing beds on a guess.
+  When it is clear, just do it.
+- The plan already records what was planted where and when. Write a journal entry only when the
+  gardener asks for one or tells you something that happened — weather, pests, a harvest, an
+  observation — not to narrate your own planting.
