# Blueprint — style guide for coding agents

> Generated from the Aesthetary record for **Blueprint**.
> Research: **Partly sourced** · Build guidance: recorded in 6 of 8 research dimensions.
> 7 sources attached. 2 claims graded by our research brief, no source attached.

## How to use this

Paste this file into your agent as context before asking it to design or build something in this visual language. It states what is established, what is our interpretation, and what nobody has established. Treat all three differently.

**The most important section is "Not researched yet".** Its purpose is to stop you and your agent inventing rules that sound right and are not recorded anywhere.

## What this language is

**Defining:** Cyanotype blue ground, white line drawings, dimension callouts, title block panel

**Recognise it by:** White line work reversed out of a saturated cyanotype-blue ground, with projected views, dimension callouts and a ruled title block: the conventions of the engineering drawing it reproduces. The blue is the chemistry of the contact print. The diagnostic condition is that the apparatus is load-bearing: the title block identifies the document and the callouts measure the object.

**Family:** Technical & Documentary
**Era:** modernist, contemporary
**Native medium:** print

**Scope:** The visual register of the cyanotype blueprint, an 1842 reproduction process: white line reversed out of Prussian blue, as Aesthetary's drawing language; the title block and dimension callouts are unverified drafting conventions we add.

## What it is arguing

A drawing that will be built from has no room for interpretation. Every line weight, callout and panel exists so that a reader in another workshop can reconstruct the object exactly, and the blueprint is the quick, cheap contact copy that carries the drawing there: white line on Prussian blue is the chemistry of that copy, not a style.

**It refuses:** Refuses perspective, decoration, and any mark that does not carry dimensional or identifying information.

## What it is not

Commonly confused with these. Getting the difference right matters more than getting the surface right:

- Engineering Drawing
- Cartographic

## Established rules

Grouped by what kind of claim each is. A requirement of the language and our own interpretation are not interchangeable.

**How to read each rule.** Every rule states two separate things, and neither stands in for the other:

- **Kind of claim** (the heading): Graded by our research brief · No source attached · From our catalogue entry · Graded by our research brief · No source attached · disputed · Documented · Source not yet verified · Documented · Source attached · Our reading.
- **Evidence** (how it is established): Graded by our research brief · No source attached (`DOCUMENTED`) · From our catalogue entry (`SUPPORTED`) · Our reading (`CURATORIAL`) · Not researched yet (`UNKNOWN`) · No grade recorded (no grade in the record). Where a claim has its own canonical label, the Evidence line gives that label instead of the grade.
- **Product area**: which of the twelve areas the rule belongs to (Layout, Typography, Color, Imagery, Surface, Interface, Motion, Motif, Technique, Form, Hierarchy, Density), mapped from its raw area label in bold. "Context" means the rule is about the Aesthetic (its name, origin, lineage) rather than a part of the design. "Not mapped" means the raw area has no single area yet.
- The code in brackets is the `grade` field at `implementationConstraints.tokenRules.value.rules[].provenance.grade` in https://aesthetary.com/data/blueprint.json. "From our catalogue entry" means: Stated in Aesthetary’s existing catalogue entry. An outside source is named only where one is linked to the claim.

### Graded by our research brief · No source attached

_A research brief graded this documented, but no source is attached yet. A grade is not a source._

- **layout** — Composition: sheet frame, corner title block, grid refs.
  - Kind of claim: Graded by our research brief · No source attached · Evidence: Graded by our research brief · No source attached · Product area: Layout

### From our catalogue entry

_Carried over from Aesthetary's original catalogue entry. The reasoning behind it was never recorded._

- **color** — Colour: cyanotype blue, white line.
  - Kind of claim: From our catalogue entry · Evidence: From our catalogue entry · Product area: Color
- **imagery** — Imagery: technical linework only.
  - Kind of claim: From our catalogue entry · Evidence: From our catalogue entry · Product area: Imagery
- **form / motif / surface / technique** — Form / motif / surface / technique: cyanotype reproduction.
  - Kind of claim: From our catalogue entry · Evidence: From our catalogue entry · Product area: not mapped

### Graded by our research brief · No source attached · disputed

- **color** — White line work reversed out of a saturated Prussian-blue ground. The colour is not a palette choice: the cyanotype process produces exactly this, and a blueprint in another colour is a drawing that is not a blueprint.
  - Kind of claim: Graded by our research brief · No source attached · disputed · Evidence: Graded by our research brief · No source attached · disputed · Product area: Color

### Documented · Source not yet verified

- **apparatus** — A ruled title block in the sheet corner carries drawing number, revision and owner. For A0-A3 sheets the standard places it bottom right.
  - Kind of claim: Documented · Source not yet verified · Evidence: Documented · Source not yet verified · Product area: not mapped

### Our reading

_Aesthetary supplied this. The source says nothing so precise. A starting point, not a fact._

- **hierarchy** — Rank by line weight, as the engineering drawing it reproduces does: outlines wide, hidden detail dashed, dimension and witness lines narrow. The print carries the drawing's widths; it adds none of its own.
  - Kind of claim: Our reading · Evidence: Our reading · Product area: Hierarchy
- **typography** — A plain single-stroke letter, capitals for titles, at one or two sizes: the freehand lettering of the working drawings blueprints reproduce. Ruled block letters were condemned in the period; templates belong to later standards.
  - Kind of claim: Our reading · Evidence: Our reading · Product area: Typography

## Found in research

What research established from sources Aesthetary opened and checked. Each line names its area, how it is known, and where it is scoped. "Seen in the work" means the source documents particular works or products rather than the Aesthetic as a whole.

- **Typography** — A 1911 engineering manual prescribes, for working drawings (which blueprints reproduce), rapid single-stroke lettering, vertical or inclined with inclined preferred, and titles in freehand single-stroke capitals.
  - Evidence: Documented · Source attached · Claim: `kcc:typography-1` · Covers working drawings, French 1911.
- **Typography** — A 1911 engineering manual condemned ruled geometrical and block letters.
  - Evidence: Documented · Source attached · Claim: `kcc:typography-2` · Covers 1911.
- **Typography** — Large offices sometimes had title forms printed in type on the tracing cloth, which then reproduced in the print.
  - Evidence: Documented · Source attached · Claim: `kcc:typography-3`
- **Typography** — Later standards list templates among lettering techniques and require lettering fit for copying processes.
  - Evidence: Documented · Source attached · Claim: `kcc:typography-4` · Covers ISO 3098-0, 1997: after the blueprint era.
- **Surface** — The blueprint is a single-layer print: Prussian-blue pigment in the fibres of uncoated paper or cloth, with no binder layer.
  - Evidence: Documented · Source attached · Claim: `kcc:surface-1`
- **Surface** — The surface is extremely matte, the paper or cloth texture is visible and usually rough, and the blue ground has continuous tone.
  - Evidence: Documented · Source attached · Claim: `kcc:surface-2`
- **Surface** — The verso is usually the colour of the support (white or off-white).
  - Evidence: Documented · Source attached · Claim: `kcc:surface-3`
- **Surface** — A 1911 manual notes that prints from some papers need more exposure and look mottled, plainly showing texture and watermarks.
  - Evidence: Documented · Source attached · Claim: `kcc:surface-4` · Covers French 1911.
- **Surface** — Supports included paper, linen (which shrank), imitation vellum and later polyester film.
  - Evidence: Documented · Source attached · Claim: `kcc:surface-5`
- **Surface** — Prints were made quickly and cheaply for an ephemeral purpose, not long-term stability; the 1911 manual says the sensitised material darkens and spoils with age or exposure to light or air; faded blueprints can regain substantial density in dark storage.
  - Evidence: Documented · Source attached · Claim: `kcc:surface-6`
- **Surface** — Corrections were made by bleaching the blue with an alkaline solution, which leaves white marks on the ground.
  - Evidence: Documented · Source attached · Claim: `kcc:surface-7` · Covers French 1911.
- **Interface** — A 1911 manual instructs that working drawings be laid out with a border and says the title is usually boxed in the lower right corner; blueprints reproduced these.
  - Evidence: Documented · Source attached · Claim: `kcc:interface-1` · Covers French 1911.
- **Interface** — Current standards put the title block bottom right on A0 to A3 sheets inside a 0.7 mm frame, and define its fields (legal owner, identification number, revision index).
  - Evidence: Documented · Source attached · Claim: `kcc:interface-2` · Covers ISO 5457 / ISO 7200: post-blueprint standards.
- **Motif** — The drafting practice blueprints reproduced rejected ornament: intricate border corners, elaborate north points and ornamental titles were condemned as a waste of time and in bad taste.
  - Evidence: Documented · Source attached · Claim: `kcc:motif-1` · Covers French 1911, on plats/land maps; the same manual condemns ornamental block lettering.
- **Motif** — The only recurring non-content marks found are functional sheet marks such as the frame and reproduction centring marks.
  - Evidence: Documented · Source attached · Claim: `kcc:motif-2` · Covers ISO 5457.
- **Form** — A blueprint is a flat, single-layer sheet, usually large, stored flat or rolled.
  - Evidence: Documented · Source attached · Claim: `kcc:form-1`

## Positions by area

The overall position recorded for each area. "No overall position recorded" means rules exist for the area but no position above them; the rules still apply. It is not the same as "Not established", which means nobody has researched the area.

- **Layout** — Specified
- **Typography** — Specified
- **Color** — Specified
- **Imagery** — Specified
- **Surface** — Specified
- **Interface** — Specified
- **Motif** — Ruled out
- **Technique** — Specified
- **Motion** — Outside this language. The area does not apply; this is not a gap in the research.
- **Form** — Outside this language. The area does not apply; this is not a gap in the research.

## Design grammar — web primitives

A starting grammar for a website in Blueprint: one matte sheet of Prussian blue, white line in a fixed width series, a frame and a ruled title block that hold real information, and nothing that measures nothing.

Three kinds of line: **On the record** names a rule this record holds (its wording is under Established rules) and states what it becomes on the web. **Web translation** is Aesthetary's choice for the web, derived from the rules it cites; change it if you have a reason, keep the cited rule. **Not specified by the source** means the research reached this but the sources say nothing about it; **Not researched yet** means the research has not reached it yet. Either way, follow the instruction and do not invent a rule. Structured version: `designGrammar` in data/blueprint.json.

### Colour

| Role | Value | Contrast | Use | Kind |
| --- | --- | --- | --- | --- |
| ground | `#16355F` | — | The print: continuous-tone Prussian blue. | On the record |
| sheet | `#1B3D6D` | — | The sheet inside the frame, one step lighter. | Web translation |
| line | `#EAF1FB` | 10.8:1 | Every line and all lettering. | On the record |
| line-muted | `rgba(234, 241, 251, 0.62)` | 5.2:1 | Field names, grid references, secondary lettering. | Web translation |

- **On the record · Graded by our research brief · No source attached · disputed** · `token_rule:bp-r1` → Reverse white line out of a saturated Prussian-blue ground; in another colour it is not a blueprint.
- **On the record · Our reading** · `claim:failure-4` → Use no colour beyond the blue ground and the white line.
- **Web translation** — Mute secondary lettering by lowering the white, never with a second hue. _Why:_ Two inks only, and the blue is continuous tone, not a palette. (`token_rule:bp-r1`, `claim:kcc:surface-2`)

### Typography

Family: a plain sans (the record declares typography free; IBM Plex is the room's choice). Stack: `"PlexSansX", "IBM Plex Sans", "Helvetica Neue", Arial, sans-serif`

| Role | Size | Weight | Line height | Case | Tracking | Measure | Setting | Use |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| title | clamp(2.25rem, 5.6vw, 6rem) | 300 | 0.95 | uppercase | 0.14em | — | — | The sheet's title, once. |
| heading | clamp(1.25rem, 2.4vw, 1.75rem) | 500 | 1.2 | uppercase | 0.06em | — | — | View titles. |
| body | 1rem | 400 | 1.6 | not specified | not specified | 68ch | — | Notes. |
| label | 0.75rem | 500 | 1.3 | uppercase | 0.1em | — | mono | Field names, grid references, scale notes. |

- **On the record · Our reading** · `claim:dcc:typography-4` → Letter plainly in single strokes, capitals for titles, at one or two sizes.
- **On the record · Documented** · `claim:kcc:typography-2` → No ruled geometric or block letters.
- **Web translation** — Title forms may be set in type rather than lettered. _Why:_ Large offices had title forms printed in type on the tracing cloth, which then reproduced in the print. (`claim:kcc:typography-3`)
- **Web translation** — Any plain sans will do; IBM Plex and its wide tracking are this room's choice. _Why:_ The record declares typography a freedom. (`claim:freedom-typography`)

### Grid and layout

One drawing sheet, continued down the screen: a white frame with an inner rule, grid references on the border, centring marks at mid-sides, the drawing's views, and a ruled title block in the lower right corner.

Tokens: frame `4px` · frame-inner `1px` · sheet-pad `clamp(16px, 3vw, 28px)`

- **On the record · Graded by our research brief · No source attached** · `token_rule:layout-3` → Compose as a sheet: frame, corner title block, grid references.
- **On the record · Documented · Source not yet verified** · `token_rule:bp-r2` → Box the title block in the corner, bottom right, holding drawing number, revision and owner.
- **On the record · Documented** · `claim:kcc:motif-2` → Mark the sheet only with functional marks, such as the frame and the centring marks.
- **Web translation** — Let the sheet continue down the page, one border from top to foot. _Why:_ A blueprint is a large flat sheet; a screen shows a large sheet by scrolling it. (`claim:kcc:form-1`, `token_rule:layout-3`)

### Shape and geometry

Tokens: line-wide `4px` · line-mid `2px` · line-narrow `1px` · radius `0`

- **On the record · Our reading** · `claim:dcc:hierarchy-13` → Rank by line width: outlines wide, hidden detail dashed, dimension and witness lines narrow.
- **Web translation** — Take every width from one series in the ratio 4:2:1 (4px, 2px, 1px here); no hairline. _Why:_ The print carries the widths of the drawing it reproduces and adds none of its own. (`claim:dcc:hierarchy-13`, `claim:idr:boundary-engineering-drawing`)
- **On the record · Our reading** · `claim:failure-2` → No decorative linework, no intricate border corners, no ornamental titles.
- **Web translation** — Keep every corner square. _Why:_ The practice blueprints reproduced condemned ornament; a rounded box is ornament here. (`claim:kcc:motif-1`)

### Imagery

- **On the record · From our catalogue entry** · `token_rule:imagery-7` → Use technical linework only.
- **On the record · Our reading** · `claim:failure-1` → Draw projected views, never perspective.
- **On the record · Our reading** · `claim:failure-3` → Give every callout a real measurement.
- **On the record · Our reading** · `claim:failure-5` → No photography.

### The print

The blue is a single-layer print, pigment in the fibres of uncoated paper or cloth: extremely matte, texture visible, continuous tone, sometimes mottled; corrections are bleached out and leave white marks.

Tokens: grain-opacity `0.09` · mottle-opacity `0.35`

- **On the record · Documented** · `claim:kcc:surface-2` → Keep the ground extremely matte, the paper's texture visible, and the blue in continuous tone.
- **On the record · Documented** · `claim:kcc:surface-7` → Make corrections by bleaching: a white mark on the ground.
- **Web translation** — Build the grain and mottle as scalable noise fills at low opacity, never a photograph of paper and never a gloss or gradient. _Why:_ The print has no binder layer and shows its support; noise at low opacity keeps the tone continuous. (`claim:kcc:surface-1`, `claim:kcc:surface-2`, `claim:kcc:surface-4`)

### Components

Anatomy, tokens and states below are Web translation: Aesthetary's specification for the screen. Each value line after them says whether it restates a rule this record holds.

#### Button

A ruled box in white line on the blue; pressed, it is bleached: white ground, blue lettering.

- Anatomy: 2px white outline; label in the mono face, capitals; square corners
- Tokens: border `2px solid #EAF1FB` · background `transparent` · hover `#EAF1FB fill, #16355F label` · radius `0` · minHeight `44px`
- State, default: White line on the blue.
- State, hover: White fill, blue label: the bleached patch. The swap is instant.
- State, focus: 2px white outline 3px outside the box.
- State, active: White fill.
- State, disabled: Dashed narrow outline, label in the muted white.
- Accessibility: White on the blue at 10.8:1, and the same pair inverted.
- Accessibility: At least 44px tall.
- **Web translation** — Draw the button as a white outline on the blue, square. _Why:_ Two inks only: white line reversed out of the Prussian-blue ground. (`token_rule:bp-r1`)
- **Web translation** — Show the pressed and hover states as a white patch with blue lettering. _Why:_ Corrections bleached out of the blue leave white marks; an inverted patch is the print's own way of changing a mark. (`claim:kcc:surface-7`)

#### Card

A lettered view: a white frame headed by its view letter in a circle, a title, and a scale note.

- Anatomy: 1px white frame; view letter in a 2px circle; title in capitals, underlined 2px; scale note in mono at right
- Tokens: border `1px solid #EAF1FB` · bubble `2px circle` · rule `2px under the title`
- State, default: Frame, letter, title, scale.
- State, hover: The title's underline doubles to 4px.
- State, focus: 2px white outline outside the frame.
- Accessibility: The whole card is one link; the letter is part of its name.
- Accessibility: The scale note is text, not decoration.
- **Web translation** — Head each card with a view letter and title, like a view on the sheet. _Why:_ Drafting conventions are the layout structure: the sheet is divided into views and a title block. (`token_rule:layout-3`)
- **Web translation** — Say only what is true in the scale note ("NOT TO SCALE" where nothing is measured). _Why:_ No callout without a real measurement. (`claim:failure-3`)

#### Input

A title-block row: the field name in the left cell, the entry in the right, ruled in white line.

- Anatomy: 2px white outer rule; 1px rule between label cell and entry; field name in capitals, muted white; entry in the sans
- Tokens: border `2px solid #EAF1FB` · divider `1px solid #EAF1FB` · height `3rem` · radius `0`
- State, default: A ruled row.
- State, focus: Outer rule to 3px, and a white outline.
- State, error: Message below in white, beginning "Error:", beside a bleached (white) mark.
- State, disabled: Dashed rules.
- Accessibility: The field name is a real label.
- Accessibility: Errors are words; there is no red to rely on.
- **Web translation** — Build a form as rows of a title block: a named field and its entry. _Why:_ The title block holds drawing number, revision and owner in ruled cells; a form is a set of named fields. (`token_rule:bp-r2`)
- **Not specified by the source** — The sources do not specify an error colour. _Instead:_ The print has two inks. Say errors in words and mark them with a white patch; do not add red.

#### Navigation

The grid references: sections lettered along the top border of the sheet, the current one boxed in white line.

- Anatomy: letters or short labels in mono capitals; spaced along the frame; current section in a 1px box
- Tokens: color `rgba(234, 241, 251, 0.62)` · current `#EAF1FB, 1px box`
- State, default: Muted white letters on the border.
- State, hover: Full white, dashed underline.
- State, focus: 2px white outline.
- State, current: Full white in a 1px box, aria-current set.
- Accessibility: Each reference is a link with its section name, not the letter alone.
- Accessibility: At least 44px tap target.
- **Web translation** — Put the navigation on the sheet's grid references, one letter per section. _Why:_ Grid references are part of the sheet's composition, and the only recurring non-content marks are the sheet's functional ones. (`token_rule:layout-3`, `claim:kcc:motif-2`)

### Motion

- **Web translation** — Do not animate; state changes are instant swaps. _Why:_ A drawing does not animate, and the source does not specify motion. (`claim:motion-reason`)

### Deliberately not added

- **A typeface** (typography): Typography is a declared freedom; the record documents lettering practice, not a face.
- **Any motion** (motion): Not specified by the source; a drawing does not animate, and this grammar chooses none.
- **Density of callouts** (gridLayout): Density is not specified by the source and is a declared freedom.
- **Screen components** (components): The record documents the sheet's own conventions (border, title block and its fields), not screen controls. All four components are translations of the sheet, the title block and the two inks.

## Coverage — what has been looked at

One row per research dimension a research pass considered. "Not researched yet" (`UNKNOWN`) means exactly that; a dimension can carry an Aesthetary recommendation and still be unresearched, and those are different things.

| Research dimension | Evidence | Resolved by | Carries a rule |
| --- | --- | --- | --- |
| Composition | Specified · Graded by our research brief | follows the recorded claim | yes |
| Typography | Specified | Aesthetary decided | yes |
| Hierarchy | Specified · Graded by our research brief | follows the recorded claim | yes |
| Colour | Specified · From our catalogue entry | follows the recorded claim | yes |
| Density | Not specified by the source | Aesthetary decided | no |
| Imagery | Specified · From our catalogue entry | follows the recorded claim | yes |
| Form / motif / surface / technique | Does not apply: form · Ruled out: motif · Specified: surface, technique | follows the recorded claim | yes |
| Motion | Not specified by the source | — | no |

Unresearched: Typography. Where a rule appears for one of these it is Aesthetary's implementation recommendation, not a property of the language, and its Evidence line above says so.

## Not researched yet

Every area of this record has a recorded position. That is unusual — most records do not.

## Grade your own work

17 checks: 8 mechanically testable, 8 needing a person to look, 0 needing a source Aesthetary does not hold, 1 with no recorded position. 2 further research dimensions produced no rule (Density, Motion). This rubric is silent on them. Scores do not add up. A failure against a required rule and a departure from something we invented are not the same result, and no total should let them cancel.

### Recognition — does this read as the intended Aesthetic?

- **[visual_human · recognition signature · Evidence: No grade recorded]** Strip every logo, word and borrowed image out of your work, then show it to someone who knows the collection. Do they land on this Aesthetic? The signature to hold is: White line work reversed out of a saturated cyanotype-blue ground, with projected views, dimension callouts and a ruled title block: the conventions of the engineering drawing it reproduces. The blue is the chemistry of the contact print. The diagnostic condition is that the apparatus is load-bearing: the title block identifies the document and the callouts measure the object.
  - _If it fails:_ The work may be competent and still read as a different Aesthetic, or as none. Nothing below matters until this passes.

### Fidelity — are its defining rules present?

- **[visual_human · Graded by our research brief · No source attached · Evidence: Graded by our research brief · No source attached]** Does your work hold this? Composition: sheet frame, corner title block, grid refs.
  - _If it fails:_ The result is not this Aesthetic. This is a requirement of the language, not a preference.

### Implementation — were those rules translated appropriately into this medium?

- **[visual_human · From our catalogue entry · Evidence: From our catalogue entry]** Your work may depart from this — but knowingly, not by accident. Colour: cyanotype blue, white line.
  - _If it fails:_ A defensible departure, and you should be able to say why you made it.
- **[visual_human · From our catalogue entry · Evidence: From our catalogue entry]** Your work may depart from this — but knowingly, not by accident. Imagery: technical linework only.
  - _If it fails:_ A defensible departure, and you should be able to say why you made it.
- **[visual_human · From our catalogue entry · Evidence: From our catalogue entry]** Your work may depart from this — but knowingly, not by accident. Form / motif / surface / technique: cyanotype reproduction.
  - _If it fails:_ A defensible departure, and you should be able to say why you made it.
- **[visual_human · Graded by our research brief · No source attached · disputed · Evidence: Graded by our research brief · No source attached · disputed]** Your work may depart from this — but knowingly, not by accident. White line work reversed out of a saturated Prussian-blue ground. The colour is not a palette choice: the cyanotype process produces exactly this, and a blueprint in another colour is a drawing that is not a blueprint.
  - _If it fails:_ A defensible departure, and you should be able to say why you made it.
- **[visual_human · Documented · Source not yet verified · Evidence: Documented · Source not yet verified]** Your work may depart from this — but knowingly, not by accident. A ruled title block in the sheet corner carries drawing number, revision and owner. For A0-A3 sheets the standard places it bottom right.
  - _If it fails:_ A defensible departure, and you should be able to say why you made it.

### Avoidance — known failure modes, neighbour drift, cloning

- **[mechanical · recorded failure mode · Evidence: No grade recorded]** Check your work against this: No perspective.
  - _If it fails:_ A failure mode recorded in our research brief: recorded judgement about what weakens this Aesthetic, not a requirement of the language.
- **[mechanical · recorded failure mode · Evidence: No grade recorded]** Check your work against this: No decorative linework.
  - _If it fails:_ A failure mode recorded in our research brief: recorded judgement about what weakens this Aesthetic, not a requirement of the language.
- **[mechanical · recorded failure mode · Evidence: No grade recorded]** Check your work against this: No callout without a real measurement.
  - _If it fails:_ A failure mode recorded in our research brief: recorded judgement about what weakens this Aesthetic, not a requirement of the language.
- **[mechanical · recorded failure mode · Evidence: No grade recorded]** Check your work against this: No colour beyond the blue ground and white line.
  - _If it fails:_ A failure mode recorded in our research brief: recorded judgement about what weakens this Aesthetic, not a requirement of the language.
- **[mechanical · recorded failure mode · Evidence: No grade recorded]** Check your work against this: No photography.
  - _If it fails:_ A failure mode recorded in our research brief: recorded judgement about what weakens this Aesthetic, not a requirement of the language.
- **[visual_human · recorded failure mode · Evidence: No grade recorded]** Have you made any of these changes? Each one moves the work into a neighbouring Aesthetic: Blueprint is not Engineering Drawing's parent, nor its child. A blueprint is a reproduction of an engineering drawing made by a contact print process, and engineering drawings are made to suit several copying processes (diazo, microfilm, telefax). The two share the drawing's conventions (projected views, title block, dimensions); Engineering Drawing is the drawing, Blueprint the cyanotype print of it. Against Cartographic: an object to be built versus terrain to be traversed. Anti-signature: decorative callouts that measure nothing; perspective; a title block holding no metadata.
  - _If it fails:_ You have built the neighbour. That may be fine — but name which Aesthetic you are in.
- **[mechanical · declared closure · Evidence: No grade recorded]** Check your work against this: Not open: perspective.
  - _If it fails:_ This one is closed, not open. The record says generation must not go here.
- **[mechanical · declared closure · Evidence: No grade recorded]** Check your work against this: Not open: decorative apparatus.
  - _If it fails:_ This one is closed, not open. The record says generation must not go here.
- **[mechanical · declared closure · Evidence: No grade recorded]** Check your work against this: Not open: empty title block..
  - _If it fails:_ This one is closed, not open. The record says generation must not go here.

### Accessibility — the Aesthetic preserved without its inaccessible practice

- **[unassessable · no recorded position · Evidence: Not researched yet (`UNKNOWN`)]** Does this Aesthetic conflict with any usability floor? Nobody has recorded one for it.
  - _If it fails:_ Nothing — and that is the problem. An unrecorded conflict is not an absent one. Hold AA on reading matter and decide the rest on other grounds.

**Not covered at all:** Density: Not specified by the source; Motion: Not specified by the source. These research dimensions produced no rule, so there is no check. Treat them as unscored, never as passed and never as failed.

## Rules for the agent

1. Do not invent rules for any area listed under **Not researched yet**.
2. Do not treat an absent position as permission to do anything you like — say that the language has no position, and decide on other grounds.
3. Keep our interpretations separable from the language's own requirements. If asked to justify a choice, cite which kind of claim it came from.
4. If you need something this record does not contain, say so rather than producing a confident answer from the aesthetic's name.
5. When you self-score against "Grade your own work", score only checks marked `mechanical`. Declare `visual_human` and `evidence_dependent` checks unjudged rather than guessing, and never score an `unassessable` one.
6. Evidence "Not researched yet" (`UNKNOWN`) is never a failure. It means nobody researched the dimension, so departing from what is written there costs nothing and must not be reported as a defect. "No grade recorded" is not a grade either: do not treat it as our decision or as an outside source.
7. In **Design grammar**, a "Web translation" line is our choice for the web and may be changed with a reason; the rules it cites may not. Never present a translation as a property of the language.
