Agent config: `OLLAMA_CLOUD_API_KEY`, `PANSY_AGENT_MODEL` (default
`ollama-cloud/glm-5.2:cloud`) and `PANSY_AGENT_ENABLED`, set in Komodo. Model
strings pass verbatim to `majordomo.Parse`, so a comma-separated spec gives
failover for free — don't parse that grammar in pansy.
`majordomo` is a **real dependency** now, resolved from the Gitea instance as a
pseudo-version. There is no `replace` directive and there must not be one: a
`replace` pointing at `../majordomo` builds on your laptop and breaks the Docker
build, which has no sibling checkout. `executus` is a sibling repo at `../` and
is not a dependency.
The `majordomo` build tag is **gone**. Don't reintroduce it — an untagged CI that
never compiles the agent is worse than a slightly larger binary.

- **garden_objects** — one polymorphic table: `kind` (`bed`|`grow_bag`|`container`|`in_ground`|`tree`|`path`|`structure`), name, `shape` (`rect`|`circle`; `polygon` + `points` JSON reserved in schema, not in the v1 editor), center `x_cm`,`y_cm` in garden space, `width_cm`,`height_cm` (circle: width=diameter), `rotation_deg`, `z_index`, `plantable` bool, nullable `color` override, `props` JSON for kind-specific extras (bed height, tree species…), notes.
- **seed_lots** — one purchase: vendor, source URL, sku, lot code, purchase date, packed-for year, quantity + unit, cost, germination %. `owner_id` is on the LOT, not inherited from the plant, so you can record buying generic built-in Garlic from Johnny's and keep it private. `plantings.seed_lot_id` (ON DELETE SET NULL) attributes a plop to a purchase; **`remaining` is derived** (quantity summed effective count of active plantings), never stored — a decremented column drifts the moment a planting is edited behind its back and can't be audited afterwards. Lots are never shared along with a garden.
- **plants** — catalog, plus `source_url`/`vendor` provenance for the variety itself. `owner_id NULL` = built-in (~30 seeded via migration, read-only, clone to customize). name, category (`vegetable`|`herb`|`flower`|`fruit`|`tree_shrub`|`cover`), `spacing_cm` (mature spacing), `color` hex, `icon` (emoji string — zero assets in v1), nullable `days_to_maturity`, notes. Users see built-ins + their own.
- **agent_conversations** / **agent_messages** — the assistant's chat, one thread per (user, garden). Only the user/assistant TEXT of each turn is stored, not the model's full transcript: continuity needs what was said and what came back, and replaying a stored tool call would replay a decision made against a garden that has since moved on. `agent_messages.change_set_id` is the handle the chat panel uses to offer Undo on the turn that caused it.
- **journal_entries** — the grow log: `garden_id` (NOT NULL), nullable `object_id`/`planting_id` to narrow the target, author, body, `observed_at`. `notes` on a garden/object/plant says what the thing IS and a new note overwrites the old; a journal entry says what HAPPENED and when, and entries accumulate. `garden_id` is set even for a bed- or plop-level entry so permission checks reuse `requireGardenRole` unchanged rather than inventing a second ACL path. `observed_at` is distinct from `created_at` — you write up Saturday's observations on Sunday. Deliberately **not** in the revision history: entries are already append-shaped and individually versioned.
- **change_sets** / **revisions** — the undo substrate. A change set groups the row-level revisions one logical operation produced (`source` ui/agent/api, `summary`, nullable `agent_run_id`, nullable `reverts_id`); a revision is `(entity_type, entity_id, op, before, after)` with full JSON row snapshots. The unit of undo is the **operation, not the row**. Revert is itself a change set, so an undo can be undone; it is version-guarded per entity and reports conflicts rather than clobbering a later edit. Garden *deletion* is deliberately not revertible (the cascade is invisible to the service, and would take the history with it).
- **plantings** ("plops") — object_id, plant_id, center `x_cm`,`y_cm` **in the parent object's local frame** (moving/rotating a bed moves its plants for free), `radius_cm` (a plop is a circular patch), nullable `count` (NULL = derived: `max(1, round(π·r² / spacing_cm²))`), nullable label, `planted_at`/`removed_at` dates. "Clear bed" sets `removed_at`; v1 shows rows where `removed_at IS NULL`. Year-over-year history and a future plan/scenario layer build on these dates without schema surgery.

10. **Garden assistant** — majordomo in-process, Ollama Cloud, streaming chat. Each turn runs inside ONE change set (`source='agent'`), so a turn that clears a bed and replants it undoes as one action; that is what makes acting without a confirmation prompt defensible. Bounded by a step cap and a timeout — loop safety, not spend control. 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.

The first account registered becomes admin, and it may register even when `PANSY_REGISTRATION=closed` to bootstrap the instance.

// Package agent adapts pansy's service layer to majordomo tools so an agent can
// drive a garden in natural language ("fill the NE corner with garlic, the NW
// with basil, the south half with beans"). Each tool runs as a fixed actor and
// therefore inherits pansy's ACL checks for free — a viewer's fill_region returns
// ErrForbidden, exactly as the REST API would.
// Package agent is pansy's garden assistant: a majordomo toolbox over the
// service layer, plus the run loop that drives a model with it.
//
// Two deliberate separations keep the core server lean:
// Every tool runs as a fixed actor, so the agent inherits pansy's permission
// checks for free — a viewer's fill_region returns ErrForbidden, exactly as the
// REST API would. That is the whole reason the tools are thin adapters over
// internal/service and never reach past it; the moment one does, the ACL story
// stops being automatic and becomes something to remember.
//
// - cmd/pansy does NOT import this package, so the server binary carries no
// agent/LLM dependencies.
// - the tool wiring (tools.go) sits behind the `majordomo` build tag, so the
// default `go build ./...` / `go test ./...` compiles without the majordomo
// module. Build the agent tools with `-tags majordomo` once majordomo is a
// dependency (`go get gitea.stevedudenhoeffer.com/steve/majordomo`).
// # A turn is one change set
//
// The agent harness itself (model loop, chat surface) lives in the
// majordomo/executus stack, outside this repo; this package is only the toolbox.
// Runs wrap their whole turn in a single change set (source "agent"), so
// "empty the garlic bed and plant cucumbers" — one object edit and a dozen
// planting inserts — undoes as one action rather than thirteen. That is what
// makes acting without a confirmation prompt defensible: the answer to "it did
// the wrong thing" is one click, not an archaeology exercise.
//
// # No build tag
//
// This package used to sit behind a `majordomo` build tag, with cmd/pansy
// deliberately not importing it, so the default build carried no LLM
// dependency. Both separations are gone, on purpose: a tag that keeps the agent
// out of the binary only earns its keep if you would ever ship a build without
// the agent, and the agent is the point. Keeping it would have meant an
// untagged CI that never compiled the code that matters.
//
// majordomo is stdlib-first and pure Go, so CGO_ENABLED=0 and the single static
// binary survive it.
//
// # Unconfigured instances
//
// With no API key the assistant is simply not offered: the chat route isn't
// registered and the capability isn't advertised — the same shape as OIDC
// 404ing when unconfigured. An instance without a key starts and serves the app
// exactly as it did before.

Conventions you cannot guess and must not assume:
- 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.
How to work:
- Start from describe_garden to see what is actually there. Do not guess ids.
- Use find_plant to turn a plant name into an id. If it returns several candidates,
pick the one 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".
- 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
and wants to know what to look at. If you changed nothing, say that too.`,
