No breadcrumb, no create CTA — back lives in the // panel and creation belongs to the REGISTER (the list owns "new"). // // GENERIC BY DESIGN: this template is the BASE every industry adapts. Flavor // lives in VALUES, never in STRUCTURE — each section below is a reusable // PATTERN, and the mock nouns stay at the common-denominator level any goods/ // services business uses (service level, destination, delivery receipt), // never one vertical's jargon. Adapt by swapping the values; keep the // patterns. // // THE SECTION PATTERNS (what each is, when to use it): // - General — the CORE FACTS: a headingless key-facts lead + named // groups + Classification (the right-input-per-field // showcase). Always present, first in rail. // - Comments — the discussion thread. When people collaborate here. // - Progress — WHERE the record sits: the desks as a `Pipeline`, each // owning its own facts, the live one owning the act that // leaves it. Records that move between owners. // - Documents — the INTAKE desk: files that ARRIVE + the ONE "Use AI" // fork (the Agents "Document desk" pattern — this template // is its worked example). // - Customer — the LINKED PARTY: another record referenced, never // edited here (the linked-record box + drawer). // - Fees — the MONEY LEDGER: cost/charge lines, both directions. // - Billing — INVOICING: charges grouped into issuable documents. // - Document set — the BATCH OUTPUT desk: the record produces per-party // form SETS on demand (readiness, fill panels, the gate). // - Delivery receipt— the QUICK-ISSUE form: one document issued from a // handful of facts at a known moment (a handover, an // inspection, a visit). // - Activity — the AUDIT TRAIL. Always. // - Handoff — the BOUNDARY: the record crosses to another desk's // table ONCE (creates + links the sibling; Recall undoes). // - Danger zone — destructive lifecycle. Always last. // // // ─── THE RULES THIS TEMPLATE ENCODES ───────────────────────────────────────── // Read these before adapting it. Each one shipped WRONG on a real app first, // was reported by the person using it, and cost a rebuild. They are not style // preferences; they are the difference between a screen that works and a screen // that gets called bland, cluttered or inconsistent. // // 1. A BADGE MEANS STATUS. Nothing else. // A lifecycle, a stage, a risk level — something that reads at a glance and // changes what you DO. A type, a category, an attribute or a count is NOT a // status: an industry, a source, a department, a headcount band, a CITY. // Those are plain `Text`. A coloured pill only means "state" for as long as // it stays scarce, so one spent on where a company happens to be devalues // the one column that IS a state. A field carrying a configured `color` is // not consent to paint it — someone set that colour for the one surface that // badges, and every other surface still has to decide. // Feed pickers with `optionPicker(options)` — text — and add // `{ badge: "dot" }` only on a status. Helper defaults must be the SAFE // answer, because a badging default reaches every call site in one sweep. // // 2. ONE VARIANT PER CONCEPT, product-wide. `dot` or `tonal`, chosen once. The // same field rendering as a filled pill on one screen and a dot on another is // the inconsistency people actually notice. Where a register already carries // identity marks, prefer `dot`: two colour systems in one row compete and // neither reads as the subject. // // 3. THE PAGE BAND IS THE TYPE ANCHOR before it is a label. Without it a record // or register tops out near 16px over a 12px floor — a 1.33x range that reads // flat at ANY amount of colour, because scale is the one hierarchy device // colour cannot replace. Accept that the title repeats the nav. Its second // line carries LIVE STATE (counts that move as you filter), never a gloss on // the widget. // // 4. A SUPPORTING LINE IS ONE RUNG BELOW ITS PRIMARY, never a fixed size. `md` // over `xs` drops 1.33x while the same shape elsewhere drops 1.17x, and the // wider pair reads as though its second line SHRANK rather than stepped. // Compare the RATIOS across the surface, not the sizes. // // 5. ACTIONABLE FIRST. Identity and the one editable status go above the fold. // An UNBOUNDED section (an activity feed, a comment thread) stacked above a // bounded field set does not order them — it BURIES the second, and the // burial deepens every time the record is used. Measured on a real record, // the fields the reader came to edit began 2,500px down. That is the case // where tabs beat one page, against the record-extent rule. // Promoting a field means MOVING it: a copy left behind gives one field two // editors on one surface, and either could be the one the reader changed. // // 6. PICK THE CONTROL BY SPECIES, from what already exists. Read // `data_entry.md`'s ladder and the `tpl_*` that covers the shape BEFORE // building. A binary filter is a `ChoiceStrip variant="chips"` (every // option visible, one press), never a popover holding one checkbox. Grouping picks a DIMENSION // via the same control species as the filters beside it, never an icon // toggling on/off. A SELECTED control needs a GROUND, not a heavier outline — // among white pills a 1px border change is invisible. // // 7. CLUSTER A TOOLBAR BY QUESTION, and check the gap RATIO. Filters answer // *which rows*; view controls answer *how are they arranged*; the CTA answers // neither. Uniform gaps make eight controls read as one undifferentiated // band; 8px within a cluster and 24px between reads as groups with no lines // or boxes added. Long labels are a toolbar defect — the band is a set of // handles, not sentences. // // 8. PICK THE FILE SURFACE BY WHAT IDENTIFIES THE FILE, after counting the real // data. Images are identified by CONTENT (grid); documents by NAME (list) — // a grid of PDFs is a wall of one grey tile. Press should OPEN a document // (`press="open"`); a preview lightbox is a dead end for anything you sign, // edit or send. A files field is `InlineFiles` in a `DetailRow`, the same // grammar as every other field beside it — never a bespoke block below the // table. A surface that can SHOW a file and cannot RECEIVE one is unfinished. // // 9. AN IDENTITY MARK MUST NOT LOOK THE SAME ON EVERY ROW — that is its entire // job. `Avatar` derives its hue from the name; circle for a person, square // for an organization. A screen whose subject is an entity and whose marks // are all one colour has the largest, brightest element in each row carrying // no information. // // 10. NEVER FORK THE KIT. Hitting a limit means fixing the kit — a component // built app-local beside one that nearly fits is a fork that drifts, and the // next author inherits both. If a prop is missing, add the prop. // ───────────────────────────────────────────────────────────────────────────── // // The lifecycle is the HANDOFF CHAIN, and it reads in TWO places by design: // `Progress` carries the position and the act that changes it; `Handoff` near // the end carries the RESULT — what each handoff created, and when. There is no // separate submit step. // ───────────────────────────────────────────────────────────────────────────── interface Customer { id: string; name: string; code: string; taxId: string; contact: string; city: string; /** Runs past one line at a peek's width — the case a fixture of short values * never exercises, and the one where a read value and its editor diverge. */ address: string; /** ISO.

A recording is MADE by the people in the meeting and merely transcribed by a service, so "Recording bot" named the plumbing and not the author — a fabricated byline on somebody else's conversation. Once that shape is refused, showing an author on the entries that happen to have one is worse than showing none: the reader learns that the byline is present when we know it, which is a fact about our pipeline. The record has an Owner, and an entry on a customer's history does not restate it eight times.

An entry's files are evidence — a scanned PO, a photo of a seal — recognised by looking, which is what a tile is for. `FilesEditor`, not a bare `FileThumbnailGrid`, because a filed attachment must be HARD to lose. The grid's ✕ sits on every tile, one click from gone; the editor's default view never draws one at all, and the only way to remove is to open the file and do it from the gallery — where you are looking at the thing you are about to delete, and it still asks.
