org 6aaf8524 20260920 000300 PDT Sun 12:03 AM 20 Sep 2026 --- revision 4: skill crafted

This document is the authoritative foundation for the skill patina. It is written to stand complete in itself: a future session possessing only this file, without conversational history, has everything required to resume, audit, or extend the work without retrograde. Every revision supersedes its predecessor in full; no revision may summarize away a prior constraint to save length. Where a later round narrows or reverses an earlier decision, the reversal and its rationale are recorded in the Decision Record rather than silently dropped. This declaration is a standing requirement for this document and its successors.

This is an ontology, not the skill. It fixes the entities, relations, keys, couplings, dispositions, library schema, report form, and roster from which the skill will be built. Operative prose, exemplars, and reverse diagnosis are deferred to crafting.


Contents


Office

Patina affiliates. It selects forms already in circulation --- words, phrases, habits of construction, analogies, allusions --- so that a reader places the author inside a parlance and receives the subject in the light the author intends.

Its target outcome is membership warrant: the reader's unreflective inference that the author belongs. Membership warrant is conferred at reading speed and withdrawn the same way; no argument secures it and no disclaimer restores it. Where coined vocabulary earns the warrant of capacity --- the author holds the material --- membership warrant is the warrant of belonging: the author holds the culture.

The operating problem. Prose synthesized by a language model is recognized by its readers, and the recognition withdraws warrant retroactively, across everything already read. Such prose is not unmarked. It belongs to a parlance of its own, one readers learned recently and recognize by its emblems. No prose is unaffiliated; the only question is with whom. Patina is a prose construction tool that also specifies the affiliation. It adds belonging to prose that had none or was synthesized, displacing the machine's markers with a culture's, and it does so without performing the culture it joins.

The name. Bronze leaves the foundry bright and uniform. Weather and handling give it, over decades, the surface that makes it look as though it has always stood where it stands. Founders do not wait for that. They patinate --- heat, chemical washes, wax --- depositing deliberately what time would deposit slowly, and the practice is a recognized finishing art rather than a counterfeit of age. The instrument is the patineur's craft applied to prose: the surface of use, laid on as finish, over a text that left synthesis bright and uniform.

The success condition is placement. A reader, unprompted, places the author inside the specified parlance and accepts the subject in the cast in which it was presented. No internal criterion outranks that one.


Boundary

The skill itself is self-contained and names no companion instrument. This table exists only to verify non-overlap during development.

Patina selects by what a form says about its speaker: the parlance it comes from, the time steeped into it, the associations it brings. When layered, patina decides which inherited forms appear; the other instruments decide how forms are struck, sounded, and delivered.

Key collisions. purpose and span are shared deliberately, each instrument resolving them independently. Patina yields on any other collision.


Entities

Parlance

The social type a text is placed inside. Five composable axes: domain (profession, trade, craft, pursuit), region, era, institution, and stance. A document carries a primary parlance and may carry secondary ones, stated as an ordered stack. A parlance is realized as a library file; a parlance named without a file resolves at the intuition tier.

Each parlance has a role: affiliate, whose markers are used, or displace, whose markers are replaced.

Marker

The atomic unit: any form whose selection indexes a parlance. Six classes.

classunittemplate example
lexicalword, jargon, slang86 --- kitchen, out of stock
phraseologicalidiom, collocation, formulathe cut of his jib --- nautical
syntactica habit of constructionobject deletion in recipe imperatives: bake until set
orthographicabbreviation, capitalization, spellingtrade abbreviations; house spellings
figurativeanalogy, simile, metaphor chosen by source domaintrim the sails for adjusting plans to conditions
allusivereference to a shared text, event, or figurea pound of flesh

Figurative and allusive markers are also bridges, defined below.

Syntactic habits are discovered, not presumed. Registers documented densely in the literature --- legal drafting, radio procedure, recipes, academic hedging --- can be derived from a named domain with reasonable reliability[^4]. For thinly documented domains, derivation from the name alone is guesswork presenting as knowledge. A syntactic habit is therefore specifiable only where the library holds it for the parlance, and the library acquires it through the discover disposition.

Salience

A property of a marker: how widely it is recognized as belonging to its parlance. At 0.0 the marker is operative, used unremarked by members and unnoticed by others. At 1.0 it is emblematic, recognized by anyone as the parlance's own[^2][^3]. Salience is stored per entry, and the emblematic key selects against it.

Patina's bias is emblematic. The aim is genuine affiliation within the reader's reach, not membership that survives an insider's scrutiny. The content of the prose carries more of the placement than any operative marker could, and emblems reach the goal more directly.

Steep

A property of a marker: the time steeped into it. It runs from new (recent in the English print corpus), through longstanding (long attested and still current), to antique (long attested, carrying its age audibly). Steep is stored per entry as attestation and status, and the steep key selects against it, as a value or as a band.

Steep is measured in print, over long baselines. Usage emerging only in speech or social media lies outside the instrument's evidence and outside its intent.

Cast

The light in which the subject is to be received. The vocabulary is open; examples are reverent, homely, wry, convivial, heroic, elegiac, urgent, austere, and comic. Cast is a property of the document (and of a region under local override), and it appears as affinity tags on library entries.

The cast is chosen before any marker or bridge is selected, because everything selected afterward carries it. It is either stated or inferred from the material; when inferred, it is reported as a claim for correction.

Terminology. "Disposition" stays reserved for the operating mode (compose, revoice, discover), following the convention of the instrument family. The subject's received light is named cast.

Bridge

A figurative or allusive marker that asserts an association between the subject and something the reader already holds. A bridge has three parts, in rhetoric's standard terms[^1]:

A bridge has one further property, attestation. It is attested where the vehicle or allusion exists in the culture as stated, and invented where synthesis made it. Invented bridges are listed in the report as candidates for the library.

Bridges are the instrument's strongest device and the chief return on synthesis. A reader accepts the unfamiliar by association with the familiar more easily than an author can justify the unfamiliar directly. Bridges therefore assert couplings the source did not make. That is their purpose, not a defect.

Association

The transfer a bridge performs. The mapping is never one to one; the association always is. Readers know an analogy is partial and forgive a thin ground. What they transfer whole is the vehicle's standing --- its familiarity, its acceptability, its cast --- to the tenor. If the vehicle is accepted, the subject is accepted by connection.

Two consequences govern both admission and amplification:

More bridges are preferred wherever they align with the cast. None are admitted where they do not.

Membership Warrant

The outcome the instrument exists to confer; the credential of belonging. It accumulates across every marker and bridge the reader accepts. It is settled at reading, never issued by the author, and withdrawn retroactively when the reader recognizes a foreign parlance --- most catastrophically the synthetic one. When membership warrant is withheld, nothing else in the document can fully redeem it. When it is conferred, the subject arrives already half accepted.

Displacement Parlance

A parlance whose markers are replaced rather than used. The principal case is synthetic: the vocabulary, phrasing, and constructions by which readers recognize model-synthesized prose[^5]. A displacement parlance is an ordinary library file with role: displace, and the displace key names which such parlances run.

Displacement is the other half of affiliation, not a rule ranked above it. The prose moves from one parlance to another: the machine's markers leave as the culture's arrive.

Library and Evidence

The library is the set of per-parlance YAML files, held in the skill's library/ directory or attached to a session. Evidence is ranked in four tiers:

  1. a library entry carrying an evidence block, such as Ngram series supplied as YAML;
  2. a library entry without evidence;
  3. dated external evidence supplied in session;
  4. model intuition.

The model's own sense of currency ranks lowest because its training distribution carries the biases the instrument works against[^6]:

Tiers are applied silently, and the calibration report counts them.

Purpose

The document class, naming a roster entry that resolves every scalar. Where a class overlaps a sibling instrument's class, the sibling's name is reused.

Disposition

The operating mode, derived from the request and never declared:

Harvest is a request, not a disposition. It asks for library entries covering the markers a compose or revoice used, for manual inclusion or exclusion in future rounds.

Keys

Direction. Each scale is stated per key; no global direction is assumed. Values read by position, not by scale: 35, 3.5, 0.35, and 7/20 place a setting identically. A setting names a region to occupy, not a limit not to exceed, and a region name may stand in place of a numeral.

Two kinds of scalar. Intensity scalars measure how much. Each has a patina pole, the end at which the key adds affiliation, and yields toward it under conflict (see Yield); their tolerance is 0.10. Polar scalars name which kind, not how much, and have no patina pole; a conflict between them is resolved by local override, never by moving toward a pole. Their tolerance is 0.20. A polar key may be stated as a band, a:b, meaning the selection ranges across it.

poeticintensityliteral: tight ground, attested allusion onlyfree: loose ground, invented vehicles and allusions, license to the hallucinogenic1.0literal .00-.20, grounded .20-.50, loose .50-.80, free .80-1.0

truss takes its name from the bridge: each analogy or allusion is a supporting member, and toward 1.0 the members multiply until the subject is carried on a full framework of support.

Bridge keys. truss sets how many bridges appear; poetic sets how freely they are made. poetic tracks truss: where an invocation states truss and not poetic, poetic moves by the same amount from its default, clamped to 0.0-1.0; where the invocation states poetic, it holds. Heavy bridging generally wants a looser license, and sparse bridging a tighter one.

neutral and truss are independent. A document may saturate its bridges while its lexical markers stay light, or the reverse.

Invocation. A purpose and a parlance form a complete invocation; everything else perturbs. Full per-purpose settings appear in the Roster.

/patina fiction parlance=[kitchen] neutral=saturated emblematic=0.90 truss=abundant poetic=free
/patina essay parlance=[commons] cast=wry cited=0.75 truss=0.80

The last line is satire, reached by perturbing essay: a wry cast and the parlance held at quotation distance.

Local override. Any setting may be overridden for a declared region, for example dialogue against narration, or a quoted passage. The override is declared as an exception. A setting wanting override everywhere is a document setting stated wrongly.


Couplings

  1. neutral with emblematic --- the caricature register. Where neutral is at or below 0.25 and emblematic is at or above 0.75, the render occupies caricature: a portrait of the parlance with its features simplified or exaggerated, and humor available. The register is named and reported, and never capped. Nothing in the instrument limits the saturation of emblematic markers, and gloss holds its setting inside the register, where a gloss may be the only means of amplification.
  1. cast with every bridge. Each vehicle carries the cast. A vehicle misaligned with the cast is not admitted at any poetic setting. This is the instrument's one admission rule, and it follows from Association.
  1. poetic with attestation. At literal, only attested allusion is admitted, over a tight ground. At grounded, invented analogies are admitted, while allusions stay attested. At loose and free, invented vehicles and allusions are both admitted. Every invented bridge is marked and located in the report.
  1. truss with poetic --- tracking. Unless stated, poetic moves with truss by the same amount, as defined under Keys.
  1. truss with cast. truss sets how many bridges appear; the cast sets which bridges may. Amplification never relaxes alignment.
  1. steep with evidence. steep filters by the attestation and status recorded in the library. Where only intuition supplies a date, the selection is counted at the intuition tier.

Yield

Intensity scalars yield toward patina: neutral and gloss toward 0.0, truss and poetic toward 1.0. The asymmetry is the inverse of the other instruments' and rests on the same ground: which failure is silent, and which is visible.

Yield governs uncertainty, not knowledge. Where a setting is stated or resolved by the roster, the center holds.


Dispositions

Compose and revoice

  1. Read the material --- the brief or the draft, entire. Infer purpose and cast, and report both as claims.
  2. Resolve the purpose roster entry, the parlance stack, and any explicit keys, then apply the couplings.
  3. Fix the cast. It precedes every selection.
  4. Gather associations. Collect candidate vehicles and allusions from the parlance library that align with the cast, as many as truss admits, within the license poetic allows.
  5. Identify displacement: the markers of every parlance named in displace present in the draft, or likely to arise in synthesis.
  6. Draft or revoice. Place lexical, phraseological, syntactic, and orthographic markers at the neutral density, the emblematic salience, and the steep band. Place bridges at the sites where the subject needs carrying.
  7. Proof for alignment. Read every bridge against the cast.
  8. Report.

Preservation under revoice. Every proposition in the source draft survives, and new figurative material is admitted. Bridges may assert associations the source did not make; that is their purpose. What may not move: a claim's content, its hedging or force, its attribution, or its presence. The delta reports propositions moved (none expected) and the count of bridges added; invented bridges are located in the report.

Discover

The input is an attached corpus. The output is candidate library entries.

  1. Name the parlance the corpus is taken to represent.
  2. Measure marker frequency in the corpus against a baseline: library evidence where present, then session-supplied evidence, then model intuition. Forms markedly more frequent than in ordinary English are candidates.
  3. Classify each candidate by class, estimate its salience, and record its steep from evidence where available.
  4. Detect syntactic habits by construction frequency --- sentence length, imperative rate, article deletion, passive rate, and the like --- and record them as syntactic entries.
  5. Emit the entries as YAML under the Library schema, for amendment by the operator.

Harvest (request)

After a compose or revoice, emit library entries for the markers and bridges used, located, for manual inclusion or exclusion. These entries are emitted only on request, never by default.

Report

Every invocation emits the calibration report in the response body, never inside the artifact. Library entries used are not listed. Invented bridges are listed, each located and given its vehicle, tenor, and cast, as candidates for library calibration uplift. Full library entries appear only on a harvest request, or as the product of discover.

Roster

These are demonstration settings only. The skill carries the actual defaults; the two are identical at the outset and may diverge as the skill is tuned by use.

Each line is a complete invocation, ready to copy and adjust. Change a value to perturb it; delete a key to return it to the skill's default; delete poetic to let it track truss. Replace name with a library parlance. cast, markers, displace, and span belong to the document rather than the purpose, and are omitted.

At null, emblematic, steep, gloss, and cited are inert.

essay, fiction, oration, letter, and recruit are shared with the sibling instruments. null is total abstention; spec and record resolve to null as aliases, so a layered invocation reads consistently across instruments. Satire is reached by perturbing essay, chiefly through cast and cited: satire works on ideas, while the caricature register works on patina. The cast is never a roster value; it belongs to the subject.
