acrostic
Enable an agent to recognise an acrostic, verify its secondary reading, assess its textual integrity, and determine which edits or reproductions preserve its defining constraint.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an agent to recognise an acrostic, verify its secondary reading, assess its textual integrity, and determine which edits or reproductions preserve its defining constraint.
An acrostic is a composition in verse or prose in which letters at corresponding positions in successive lines or other textual units, most commonly the initial letters, spell a word, name, message, or ordered sequence when read in order.
It can be Extract the secondary sequence with a trace from each selected unit to its carrier position.; Test a stated acrostic rule and report omissions, substitutions, and other exceptions.; Generate or revise carrier text against an explicit target sequence and selection rule.; Compare versions to identify changes that preserve or disrupt the acrostic.; Annotate the secondary reading while distinguishing extraction evidence from interpretive claims.; Assess whether a proposed translation or presentation preserves the constraint or needs an explanatory note..
Distinguishing features
A reproducible rule selects textual units from an ordered series of carrier units; merely noticing a suggestive substring is insufficient.
In the central initial-letter case, reading the first letters of successive lines produces the secondary sequence without rearranging them.
Alphabetic acrostics can follow an alphabetic sequence rather than spelling a separate word or sentence.
The carrier text retains its ordinary reading while supporting a second structural reading, unlike an isolated acronym alone.
Identification depends on specified textual boundaries and positions; arbitrary skipping or changing selection rules weakens the claim.
Scope
+ The relationship between the carrier text and its secondary reading
+ Segmentation, ordering, selection positions, and extraction rules
+ Message-bearing and alphabetic acrostic constraints
+ Evidence of deliberate construction and the strength of an identification
+ Version, translation, and presentation changes that preserve or disrupt the acrostic
- General poetry analysis unrelated to the acrostic constraint
- The complete bibliographic description of editions and individual copies
- General cryptographic systems and claims of secure concealment
- Crossword-style acrostic puzzles as games with clues and solving rules
- Ownership and licensing determinations beyond links to applicable rights records
Characteristics
- Carrier segmentation
- lines, verses, stanzas, words, or explicitly defined textual units Determines which units contribute to the secondary reading and whether layout changes alter extraction.
- Selection rule
- initial letters; final letters; internal positions; multiple positions; other explicitly stated rule Makes extraction reproducible and exposes variants whose inclusion requires a stated scope convention.
- Reading order
- carrier order, reverse carrier order, or another explicitly evidenced order Prevents an agent from silently rearranging units to manufacture a result.
- Secondary sequence role
- name, dedication, message, alphabetic sequence, other, unresolved Separates the extracted sequence from an interpretation of its purpose.
- Constraint coverage
- conforming carrier units / expected carrier units, with exceptions identified Shows whether the acrostic is complete, partial, damaged, or dependent on exceptions.
- Construction evidence
- explicitly attested, structurally supported, conjectural, disputed Distinguishes verifiable extraction from certainty about authorial intention.
- Textual witness
- link to the particular manuscript, edition, transcription, or digital expression inspected An acrostic may survive in one textual version and fail in another.
- Transformation integrity
- preserved, altered, broken, untested Supports decisions about editing, translation, reflow, and reproduction.

Acrostic identity Establishes which textual phenomenon is being identified and the boundaries of that identification.
The agent must distinguish an acrostic constraint from an acronym, accidental pattern, or separately modelled puzzle.
Form and instance
Separates the general form from its occurrence in a particular text.
Carrier and secondary reading
An individual acrostic relates an ordinarily readable carrier text to a secondary sequence obtained from selected textual positions.
- Which passage is the carrier, and what secondary sequence is claimed for it? definition
- Does the claim concern the whole work or only a bounded passage within it? boundary
Variant boundaries
Makes the naming convention and neighbouring forms explicit.
Central case and extensions
Initial letters of successive lines provide the central recognition case; other positions or carrier units require an explicit classification convention.
- Does this example select initial letters of lines, or does it use a different position or carrier unit? definition
- Under the terminology used by the consulted source, are final-letter and internal-letter constructions included as acrostics or treated as neighbouring forms? boundary
Extraction mechanics Records how the secondary sequence is obtained without hidden choices.
An acrostic claim is operationally useful only if another agent can repeat its extraction.
Carrier units
Defines the units and boundaries from which characters are selected.
Segmentation and character handling
Extraction depends on stable carrier boundaries and declared treatment of punctuation, spaces, and script-specific character units.
- Which line, verse, stanza, or word boundaries govern selection, and are they textual boundaries or display wrapping? definition
- How are leading punctuation, whitespace, diacritics, and multi-code-point letters handled? measurement
Selection and order
Specifies selection positions and traversal order.
Reproducible extraction
A traceable extraction identifies every contributing position and preserves the raw result separately from interpretive spacing or normalisation.
- What position is selected from each carrier unit, and in what order are the units traversed? measurement
- What exact sequence results before adding spaces, changing case, or normalising spelling? measurement
- Can the agent expose each selected character alongside its carrier location? action
Constraint and evidence Evaluates structural conformity and the support for claims about meaning or intention.
A readable extracted string does not by itself establish deliberate construction or its intended interpretation.
Structural conformity
Tests the carrier against the stated target or sequence rule.
Target and exceptions
Conformity must be assessed against the actual constraint, which may be a message, an alphabetic progression, or another specified sequence.
- Is the expected result an independently attested target, an alphabetic sequence, or an interpretation proposed after extraction? provenance
- Which expected positions conform, and which require omissions, substitutions, repetitions, or uncertain readings? measurement
Intent and interpretation
Separates structural observation from claims about why the acrostic was made.
Supported acrostic claim
Evidence for extraction, intentional construction, and the meaning of the extracted sequence should be assessed separately.
- What authorial statement, manuscript feature, editorial account, or structural evidence supports deliberate construction? provenance
- Which interpretation of the extracted name or message is supported, and which alternatives remain unresolved? boundary
- Should the agent present the identification as attested, structurally supported, conjectural, or disputed? action
Transmission and preservation Tracks the acrostic across textual witnesses, transformations, and presentations.
Edits that leave the ordinary meaning broadly intact can destroy the secondary reading.
Witness and version
Anchors extraction to the inspected expression and compares alternatives.
Version-specific integrity
The acrostic structure belongs to a particular textual expression; editions, transcriptions, and translations must be checked individually.
- Which exact witness or version was inspected, and where can its relevant passage be located? provenance
- Do variant wording, spelling, missing lines, or changed segmentation alter the secondary sequence? measurement
Transformation decisions
Supports constraint-aware editing, translation, and display.
Preserve or document change
A transformation should declare whether it preserves the original secondary sequence, creates an adapted one, or loses the constraint.
- Must the proposed edit or translation preserve the exact secondary sequence, its role, or only explain the original construction? action
- Which line boundaries and selected characters must remain stable when the text is reflowed or exported? action
- After transformation, does re-extraction verify preservation, or must the changed acrostic be documented as an adaptation? measurement
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- Acronym - An acronym forms an abbreviated name or word from initial letters; an acrostic embeds a sequence in corresponding positions across a composition.
- Acrostic puzzle - An acrostic puzzle is a solving activity that uses acrostic relationships; an acrostic composition need not be a puzzle.
- Steganography - Steganography conceals the existence of a message; an acrostic can serve that purpose but may openly display its organizing pattern.
- Concrete poetry - Concrete poetry uses visual arrangement as part of its meaning; an acrostic specifically encodes a sequence through selected textual positions.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of acrostic this model covers, and on what evidence? provenance
What the second pass must settle
- Does the registry intend the narrow initial-letter sense or a broader family including final-letter, internal-letter, and multiple-position constructions?
- Which authoritative terminology should govern alphabetic acrostics and variants that repeat each alphabetic letter across several carrier units?
- What evidence threshold should distinguish deliberate construction from a coincidental secondary sequence in an unannotated text?
- Which script-specific rules are needed for grapheme selection, historical spelling, and reading direction?
- Does an existing Vercy world model already own this concept, requiring this registry entry to link to it rather than receive a separate publication?
