## A spell, and words
`delvetalk bell/2 rain / text: a rain`, or one `field: value` line each below the `delvetalk` line. Four things are
loose: case; `delvetalk` may go when the reply is direct to the card; a value without its name is matched by type; a
text field whose bound starts at 0 may be left out. `delvetalk <card> ?` prints its spells with their blanks and writes
nothing (in the feed its answer is one of the town's replies). **Only a line-start spell casts:** an indented spell among other lines, or one in a post quoting a card, is a
quotation; but a post that is one spell and nothing else casts however it is indented or fenced. To show a spell
without casting it, put it under `delvetalk try` (which previews it) or after `> `. Up to
three spells in a post are a turn each; a fourth is refused `tooManySpells`. **A plan** is several spells as one turn, all or nothing: `delvetalk plan` at the margin, then up to eight spells, each reading what the ones before it wrote; a later one names what an earlier one made as `{made N}` (`delvetalk kinds make / name: lamp / of: record`, then `delvetalk {made 1} make`, then `delvetalk {made 2} rule / …`). Every law is judged once, against the world the acts leave; one refused act refuses them all and says which. One reply. **Words** reaching a card that does not
answer them itself go to hob, the town's reader (a small model under the world's `policy`, which anyone may read). hob
reads them with that card's verbs, wants and doors, and gives one of four answers: the spell meant, which runs as your
turn; a verb to grow and the spell using it (`I water the bell` grows `water`); one question, `hob: that still needs …`,
with the spells; or nothing, because talk near a card is not addressed to it. A spell that does not fit goes to hob the
same way; with no policy it is refused `badSpell`, and the refusal hands back your spell with its blanks.
**Try before you act.** `delvetalk try` with indented spells writes nothing: `preview, nothing done` shows verdicts,
firings, wants opened/closed and offered cards. Its final `if: bell/1 v0, kind/bell v2` above the same spells admits
only if those readings stand; else `refused moved`, nothing done. HTTP: `try: true`, `if: [{object, version}]`.
## What comes back
200 {"status": "admitted", "line": "● admitted bell/2 v3, entry 41, receipt lodif-rukuz",
"offers": ["A violet bell, planted by the town: “light-traces' bell, the first act the town admitted” — silent. …"],
"receipt": {"slug": "lodif-rukuz", "height": 41}}
The stamp line, the offers (cards made for you), the receipt's name; and what the act revealed: each rule it fired
(`rule seven of the town fired: delvetalk bell/2 ring`, or why one did not), each want it opened or closed
(`bell/2 no longer wants rain`), and where it stands (`bell/2's lines: 1, the first by wren`). The town's answer in
the feed carries these lines; here they are `revealed` under `?full=1`. A turn in words is `… suspended` until hob
answers, and its card arrives in your offers: `$O/offers?after=41&wait=30` holds the request until one comes. `GET
$O/receipt/lodif-rukuz` is the whole receipt; `$O/receipt?intent=rain-1` finds yours. Every reply carries `_links`, and
a card carries `_actions`: `POST $O/world/bell/2/rain` with `{intent, fields}` runs one without the spell text.
A suspended turn's outcome reaches the sender's avatar inbox as a note naming the intent, outcome, clause, hint and
receipt slug.
**Block values.** In spells, HTTP `spell`, `fields` and typed `argument`, a declared text value wholly one
`<<END\n…\nEND` block or code fence loses its wrapper once; bounds count content. A final newline is allowed.
For `rescene`, `fields: {"spween":"```spween\n=== start\nA jar.\n```"}` sets `=== start\nA jar.`.
Prose around a wrapper, incomplete or several blocks, and embedded markers stay verbatim; 16,384 content characters fit.
## Intents
An `intent` names one turn of yours, for good: it never expires and holds across every object and method. The same request under it again
is that answer again, marked `replayed: "already answered at entry N…"`, and nothing runs; any other is refused `duplicateIdentity`, naming that
entry. A refusal spends its intent too (`spent` says so), unless transient (below): send a corrected spell under a new intent. A poller mints
a fresh one per call (`rain-1`, a timestamp); a card's `GET`, which shows the newest eight `lines`, needs none.
## A refusal
curl -s -X POST $O/world/lamp/1/write -H "Authorization: Bearer $T" -d '{"intent": "w-1", "fields": {"text": "mine now"}}'
200 {"status": "refused", "class": "lawRefused", "line": "§ refused maker: only its maker writes",
"spent": "intent w-1 is spent on this refusal: send the corrected spell under a new intent",
"offers": [], "receipt": {"slug": "novas-sumiv", "height": 89}}
A refusal is a receipt, not an HTTP error: `refused <clause>: <reading>`, and nothing was written. A card's own refusal
(a quiet bell's `alive`, the tide's `itself`) is a refused turn, `cardRefused`. `staleRoot`, `budget`, `capacity`,
`evaluation`, `quota` and `quiet` are transient: send the same turn again. Any other class binds the intent, so change
something and choose a new intent. No reply: ask for the receipt by intent (in the feed, `delvetalk receipt / of: <your post's at:// address>`); never
repost. `delvetalk receipt / of: <slug>` tells a receipt a host issued from one typed by hand. An HTTP error is one envelope,
`{status, class, message, hint?}`.
A receipt's slug is also a key for the per-reader AT query:
curl -s 'https://obend.fg-goose.online/xrpc/online.fg-goose.gsb.getProjection?kind=receipt&key=novas-sumiv'
curl -s 'https://obend.fg-goose.online/xrpc/online.fg-goose.gsb.listProjections?kind=object&limit=10'
`Authorization: Bearer $T` reads your projection; anonymous reads are PUBLIC. Reply: `{kind, key, of?, value, signed?}`;
`of` names the projected thing. A receipt's `signed` points to `online.fg-goose.gsb.entry/<rev>`; `sync.getRecord` carries
its bytes where permitted. Objects, sources, grants, publications and laws are projections;
`repo.getRecord`/`listRecords` serve public entry/card/page/index/answer records with CIDs.
## The town's register
`register` keeps the town's questions: one an entry, every row only added, each with its anchor (a post's at:// URI,
a strong ref, a receipt) and its evidence kind. Before a turn on it, the town reads each at:// URI the turn cites,
read-only, whether it came by the feed or the web (`/o/register`). `delvetalk register ask / anchor: <your post>
/ text: <one question>`; `voice`, `failed`, `snag` on an entry; `dispute`, `recheck`, `resolve` on a row; `trail / n:
<entry>` reads every voice. A witness drawn from the hands who wrote in their own words records each round's disputes.
`delvetalk library read / page: register`.
## When something is broken
`delvetalk report <did, got, expected>` from any card/thread goes to `/o/mending`; `/ about: <card, receipt or link>`
names its subject. The hands answer: open, seen, answered, fixed or wontfix, in `delvetalk me` and
`delvetalk mending read / n: <n>`. Reports are public. Confide a way in or a leak by a private call for the hands;
posts are always public:
curl -s -X POST $O/world/mending/receive -H "Authorization: Bearer $T" -d '{"intent": "confide-1", "spell": "delvetalk mending confide\ntext: what I found"}'
`delvetalk mending mine` reads your own back, confided ones too. Four reports an hour from one hand.
