Patina

No prose is unaffiliated. Prose that sounds like nowhere sounds, to a reader who has learned the machine's parlance, like the machine. This instrument chooses the affiliation.

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.

Activation

Any one condition is sufficient.

• Prose should read as coming from a particular parlance: a trade, a region, an era, an institution, a stance.
• A draft reads as sterile, or as synthesized.
• A subject needs carrying to its reader through analogy or allusion the reader already holds.
• An attached corpus is to be mined for library entries.

Self-contained: no prior session, no companion instrument, and no vocabulary beyond what is current in rhetoric and sociolinguistics.

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. It mints nothing. Every form it places was in use before the document, and its value is that the reader has met it elsewhere.

Membership warrant is the outcome: the reader's unreflective inference that the author belongs. It accumulates across every marker and bridge the reader accepts. It is settled at reading speed and withdrawn the same way --- retroactively, across everything already read --- when the reader recognizes a foreign parlance. The synthetic parlance is the commonest foreign parlance, and recognizing it is the costliest: a reader who has placed prose with the machine returns no membership warrant for anything the machine appears to have said.

Patina therefore works in two directions at once. Displacement removes the markers of the parlance the prose is leaving; affiliation places the markers of the parlance it is joining. Neither ranks above the other; they are one move.

The name. Bronze leaves the foundry bright and uniform, and 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 finishing art rather than a counterfeit of age. The instrument is that craft applied to prose.

Emblematic by bias. The aim is genuine affiliation within the reader's reach, not membership that survives an insider's audit. Members recognize one another by operative markers, forms used unremarked; readers at large recognize a parlance by its emblems. The content of the prose carries more of the placement than any operative marker can, so selection leans emblematic. Saturation is the author's to choose, up to caricature: a portrait of the parlance with its features simplified or exaggerated, and humor available. Caricature is a register, not a fault.

Invocation

Tier one --- a purpose and a parlance. Complete; nothing else is required.

/patina essay parlance=[kitchen]

The purpose may be omitted where the material shows it, and the parlance where the subject implies one. Either inference, and the cast, are reported as claims for correction.

Tier two --- what an operator says next.

/patina essay parlance=[kitchen] cast=wry
/patina letter parlance=[nautical, commons:secondary] truss=0.80
/patina memo parlance=[unix-admin] markers=[lexical,figurative] steep=new
/patina fiction parlance=[kitchen] displace=[synthetic, legalese]

cast names the light the subject is received in; truss how heavily the subject is carried by analogy and allusion; steep the time in the forms; markers the classes admitted; displace the parlances replaced.

Tier three --- region names on keys, tabled under Keys. A region resolves to its center, with its width as tolerance.

/patina letter parlance=[nautical] neutral=marked truss=frequent poetic=loose steep=antique

Tier four --- numerals and bands. A polar key may take a band, a:b, and selection then ranges across it.

/patina essay parlance=[kitchen] neutral=0.35 emblematic=0.80 steep=0.40:0.90

Values read by position: 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. Numerals are the report's language, and an operator at tier four is normally answering a report just read.

Roster lines are complete invocations. Copy one from the Roster, change a value to perturb it, and delete a key to return it to its default.

Disposition

Derived from the request, never declared.

• revoice --- a draft is present.
• compose --- no draft; a brief, an outline, or a subject.
• discover --- an attached corpus, with a request to build or extend a library.

Harvest is a request, not a disposition. After a compose or revoice, the operator asks for library entries covering the forms placed.

Compose and Revoice

Passes one and two run separately over the whole document and are not interleaved.

1. Read the material entire. Infer purpose, the parlance where unstated, and cast; report each inference.
2. Resolve per Resolution.
3. Fix the cast. It precedes every selection, since everything selected afterward carries it.
4. Pass one --- truss. Find the sites where the subject needs carrying: the unfamiliar concept, the abstract claim, the point where the reader must assent. Gather vehicles and allusions aligned with the cast, from the parlance stack first and the commons after, as many as truss admits and as freely as poetic allows. Place them. Bridges reshape sentences and paragraphs, so they go in first.
5. Pass two --- surface. Displace the markers of every parlance in displace. Place lexical, phraseological, syntactic, and orthographic markers at the neutral density, the emblematic salience, and the steep band, under the gloss and cited settings. Markers substitute within sentences the first pass has already built.
6. Proof for alignment. Read every bridge against the cast. A bridge in the wrong cast is removed or replaced, never kept for its ground.
7. Check the delta (revoice) per Preservation, then report per Report.

Under compose, pass one runs at the outline, siting bridges before sentences exist, and pass two runs at the draft.

Preservation

Applies under revoice. Every proposition in the source draft survives.

May move: diction, idiom, sentence boundaries, clause order, paragraph rhythm.

May be added: bridges. An analogy, simile, or allusion asserts an association the source did not make, and that is the device's purpose.

May not move: a claim's content, its hedging or force, its attribution, or its presence. No claim about the subject may appear outside a bridge.

The delta is a report line, present whether or not it is empty: propositions moved, each located (none expected), and the count of bridges added. An empty delta is stated rather than omitted, since a line appearing only on failure trains the operator to read for its absence.

Cast

The light in which the subject is to be received. The vocabulary is open; common casts include reverent, homely, wry, convivial, heroic, elegiac, urgent, austere, pragmatic, and comic. The cast is stated or inferred, and when inferred it is reported as a claim. A region may carry its own cast by local override.

The cast is the one property no roster supplies: it belongs to the subject. It governs bridge admission absolutely, and marker selection by affinity. Library entries carry cast tags, and an entry whose tags oppose the cast is passed over while an aligned one exists.

Truss

A bridge is a figurative or allusive form that asserts an association between the subject and something the reader already holds. It has three parts[^1]:

• the tenor, the subject carried;
• the vehicle, the familiar thing that carries it;
• the ground, what the two share.

Each bridge is attested, existing in the culture as stated, or invented, made by synthesis.

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. A reader accepts the unfamiliar through the familiar more easily than an author can justify the unfamiliar directly, and this is the chief return on synthesis: the bridges no source supplied.

Two consequences govern both admission and amplification:

• A marginal analogy in the right cast outperforms a fidelity that leaves the subject without flavor.
• An exact analogy in the wrong cast carries the subject into a light it should not be received in, however sound its ground.

The admission rule. A vehicle misaligned with the cast is not admitted at any setting. Wherever bridges align, more are preferred, up to the density truss sets. The key takes its name from the bridge: each analogy or allusion is a supporting member, and toward 1.0 the members multiply until the subject rests on a full framework of support.

Vehicles from the parlance do double work. A vehicle drawn from the parlance stack carries the subject and affiliates the author in one form. The commons --- allusion held by English readers generally --- supplies the rest. The most frequent vehicles in synthesized prose, the double-edged sword and the well-oiled machine among them, are markers of the synthetic parlance, and are displaced like any other.

poetic sets how freely bridges are made.

• 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, and the ground may run thin. At free, the figure may run to the hallucinogenic.

Every invented bridge is listed in the report, located, as a candidate for the library.

Markers

A marker is any form whose selection indexes a parlance.

Figurative and allusive markers are also bridges, governed by Truss.

Salience runs from operative, used unremarked by members, to emblematic, recognized by anyone as the parlance's own[^2]. Steep runs from new in print, through longstanding, to antique. Both are recorded per library entry; emblematic selects against salience and steep selects against steep.

Syntactic habits are discovered, not presumed. Registers documented densely --- legal drafting, radio procedure, recipes, academic hedging --- can be derived from a named domain[^3]. For a thinly documented domain, derivation from the name alone is guesswork presenting as knowledge. syntactic is therefore admitted only where the library holds habits for the parlance, and discover is how the library comes to hold them.

Displacement. A parlance with role: displace supplies markers to replace. The replacement is the affiliating parlance's marker wherever an entry displaces the form; otherwise it is the plainest form the parlance would use. synthetic, the forms by which readers recognize model-synthesized prose[^4], is the principal case and the default.

Keys

Seven scalars and six denoted settings. Two kinds of scalar.

Intensity --- neutral, gloss, truss, poetic. Each has a patina pole, the end at which the key adds affiliation, and yields toward it under conflict. Tolerance 0.10.

Polar --- emblematic, steep, cited. These name which kind, not how much. They have no patina pole and no yield direction; a conflict resolves by local override, never by moving toward a pole. A polar key may be stated as a band. Tolerance 0.20.

truss and neutral are independent. A document may be heavily trussed while its lexical surface stays light, or the reverse.

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.

Resolution

1. purpose --- stated, or inferred from the material. Resolves every scalar.
2. parlance --- stated, or inferred from the subject. Each parlance's library file is loaded; an attached file supplements a directory file of the same name and replaces it entry by entry. A parlance with no file resolves at the intuition tier and is reported so.
3. cast --- stated, or inferred.
4. Explicit keys --- override the roster.
5. Tracking --- poetic follows a stated truss unless poetic is itself stated.
6. Couplings --- applied last, and reported rather than applied silently.

Couplings.

• The caricature register. Where neutral is at or below 0.25 and emblematic is at or above 0.75, the render occupies caricature. 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.
• Cast with every bridge. This is the admission rule under Truss; no setting relaxes it.
• truss with markers. truss requires figurative or allusive among the admitted classes. With both excluded, truss is inert, and the report says so.
• steep with evidence. steep filters by the attestation and status recorded in the library. Where only intuition supplies a date, the selection counts at the intuition tier.

Evidence. Four tiers, in rank order:

1. a library entry carrying an evidence block;
2. a library entry without one;
3. dated external evidence supplied in session;
4. model intuition.

Intuition ranks lowest because the model's sense of what is current carries the biases the instrument works against: emblems are what gets written about, knowledge anchors at a training cutoff, and print and web registers outweigh speech[^5]. Tiers apply silently, and the report counts them. The instrument never fabricates a frequency series, and it never claims a trajectory the evidence does not show.

Local override. Any setting, the cast included, may be overridden for a declared region: dialogue against narration, a quoted passage, a section with a cast of its own. The override is declared as an exception. A setting wanting override everywhere is a document setting stated wrongly.

Yield

Intensity scalars yield toward patina: neutral and gloss toward 0.0, truss and poetic toward 1.0. The reason is which failure is silent and which is visible.

• Sterility fails silently and catastrophically. The reader recognizes the synthetic parlance, withdraws membership warrant retroactively, and says nothing.
• Excess fails visibly and recoverably. It is caught in proofreading and corrected at revision, before it has consequence.

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

Library

One YAML file per parlance, in the skill's library/ directory or attached to a session. Files whose names begin with _ are documentation and are never loaded as parlances. Ngram development arrives as evidence blocks inside library files.

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 form frequency against a baseline: library evidence where present, then session evidence, then intuition. Forms markedly more frequent than in ordinary English are candidates.
3. Classify each candidate, estimate its salience, and record its steep from evidence where available, marking the tier.
4. Measure construction frequency --- sentence length, imperative rate, article deletion, passive rate, and the like --- and record the habits found as syntactic entries.
5. Tag cast affinities, glosses, and, for figurative candidates, the tenors each vehicle can carry.
6. Emit the entries as YAML under the Library schema, for amendment by the operator.

Harvest

On request, after a compose or revoice: emit library entries for every marker and bridge placed, each located. An entry already in the library is emitted with its current values, for amendment or exclusion. A form not yet in the library is emitted as a new entry, marked with its tier. Harvest is the only occasion on which library entries appear in a response, apart from the product of discover.

Report

Every invocation emits the calibration report in the response body, never inside the artifact. The artifact carries prose. The response carries the settings, so a revision request names a key rather than describing a symptom.

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.

At null, emblematic, steep, gloss, and cited are inert. null is total abstention, named so it can be invoked, and spec and record resolve to it as aliases.

Where inference is likely to go wrong:

• oration reaches for the antique band, where proverb and scripture carry a room.
• manual keeps bridges few and literal, because its reader acts on every sentence.
• recruit sits just outside the caricature register, so a recruiting voice enters it only by choice.
• Satire is not a purpose. It is essay perturbed, chiefly through cast and cited: satire works on ideas, and caricature works on patina.

Reverse Diagnosis

• "This reads like AI" ---> displacement did not run, or the synthetic library is thin; check displace, then neutral. Check the bridges too: stock vehicles are the machine's markers.
• Correct, competent, anonymous ---> neutral too high. The synthetic parlance holds by default, and no reader will name the loss.
• Costume, trying too hard ---> the caricature register was entered without being chosen; read the register line and lower emblematic or raise neutral.
• "I couldn't follow the jargon" ---> gloss too low for this reader, or emblematic too low, so that operative markers only members read are being placed.
• Dated, a period piece ---> steep too high for the purpose, or its band too narrow at the antique end.
• The analogy cheapened the subject ---> the cast is wrong, or a bridge escaped the alignment proof. Correct at the cast, never by stripping bridges.
• The subject is lost among its figures ---> truss too high for the subject's weight, or poetic rose with it by tracking. State poetic to hold it.
• A reader challenges an allusion's source ---> an invented allusion under loose or free where the reader expected attestation. Read the invented list; lower poetic for this document.
• The right parlance, the wrong community within it ---> the stack is under-specified; add a secondary parlance or a region axis.
• Accurate markers, and still the prose reads translated ---> syntactic habits are absent; the library lacks them, so run discover.
• Ironic where sincerity was intended ---> cited too high.
• A claim moved, dropped, or appeared outside a bridge ---> preservation violated. Correct the render, not the setting, and carry the finding into the delta.
