Term-Stability Review¶
Terminology audit — instantiates Metanarrative Coherence and Internal Consistency Check
Pins each load-bearing term to a single definition and tracks it through the whole narrative, flagging the passages where a word quietly changes meaning to keep an argument alive — semantic drift used to dodge a contradiction.
A narrative can pass every claim-level check and still be incoherent for a reason the others cannot see: a single word that means one thing in the introduction and quietly means another by the conclusion. Term-Stability Review hunts exactly this. It builds a glossary of the narrative's load-bearing terms, fixes a single working definition for each, and then tracks every use of the term across the whole text, flagging the passages where the meaning has drifted. Its defining move, and the one thing no sibling shares, is that its unit of analysis is the term, not the claim: it holds a word constant and watches for its meaning to slip, rather than holding meanings constant and watching for claims to clash. It targets the archetype's most slippery failure — "semantic drift laundering," where a key term changes meaning precisely so that a contradiction never surfaces, because the two incompatible claims turn out to be using the same word for two different things.
Example¶
A legislature debates a bill whose accompanying justification narrative leans entirely on helping small business. A legislative analyst runs a term-stability review over the narrative before the floor vote. She fixes the glossary entry from the bill's own definitions section: small business = fewer than 50 employees. Then she tracks every appearance of the phrase through the justification.
The drift is systematic. The opening — "small businesses are the backbone of the local economy" — clearly means the corner shop, a handful of employees. But the section justifying the largest tax break uses "small business" to mean "under $25 million in revenue," which sweeps in firms of several hundred employees. And the eligibility clause quietly reverts to the 50-employee line. Laid side by side in the glossary's tracking column, the term carries three different scopes in one document, and the shift is not innocent: the widest definition appears exactly where it justifies the benefit that flows mostly to the largest "small" firms, while the sympathetic corner-shop meaning does the persuasive work up front. The review does not judge the policy; it shows that the narrative's central term is doing incompatible jobs in different passages — a motte-and-bailey riding on one phrase — so the drafters must either mark the shift openly or pick one meaning.
How it works¶
- Extract the load-bearing terms. Identify the words the narrative's argument actually rests on — the ones that, if their meaning moved, would change what the story proves — and leave ordinary vocabulary alone.
- Fix one working definition each. Pin a single sense per term, drawn from the narrative's own definitions where it states them, so drift is measured against a declared baseline rather than the reviewer's preference.
- Track every use against the baseline. Walk each occurrence and check its meaning-in-context against the fixed sense, applying the stability criterion: one term, one meaning, unless a shift is explicitly marked as a shift.
- Flag drift versus marked shifts. Separate legitimate, signposted evolution of a term ("by 'freedom' here I now mean...") from silent slippage, and note where an incompatibility between claims dissolves — or hides — once the equivocation is exposed.
Tuning parameters¶
- Term-selection threshold — how load-bearing a word must be to enter the glossary. A low threshold tracks everything and buries the argument-critical terms in trivia; a high one stays focused but can miss a quietly pivotal word.
- Definition tightness — how narrowly each baseline sense is fixed. Tight definitions catch subtle drift but flag every ordinary nuance as slippage; loose ones tolerate real variation but let genuine equivocation pass.
- Marked-shift allowance — how readily a change of meaning is accepted as a legitimate, signposted evolution versus flagged as drift. Generous allowance respects living language; too much of it lets any equivocation be excused as "of course the meaning developed."
- Context sensitivity — how much surrounding text is read to judge a term's meaning in a passage. Deeper context distinguishes true drift from harmless local color, at higher cost per occurrence.
- Cross-section scope — whether the review checks a term only within sections or across the whole narrative. Whole-narrative tracking catches the intro-to-conclusion slide that within-section review never sees.
When it helps, and when it misleads¶
Its strength is that it catches incoherence hiding below the claim level, where a contradiction scan is blind: two claims that seem compatible only because their shared term is silently doing double duty, or two that seem to clash only because a word drifted. Holding a term to one meaning is the discipline against the motte-and-bailey, where an argument defends an easy sense of a word and then trades on a stronger, different sense.[n1] It is the natural partner of the contradiction scan, since many apparent contradictions — and many hidden ones — turn out to be a single term equivocating.
Its failure mode is pedantic rigidity: language legitimately evolves within a long narrative, and a review that flags every nuance as "drift" will manufacture incoherence out of ordinary richness, especially in literary or philosophical texts where a term is meant to deepen as it is used. The classic misuse is the reverse — weaponizing a hyper-strict definition to convict an opponent's argument of equivocation it never committed. The discipline that guards both directions is the marked-shift rule: a term may change meaning, but the change must be declared, and drift is only a fault when it is silent and when the silence is what lets an otherwise-visible contradiction survive.
How it implements the components¶
terminology_glossary— its core artifact: the register of load-bearing terms, each with a fixed working sense and a tracked record of how the term is used across the narrative.consistency_criteria— it defines and applies the semantic-stability criterion specifically: one term holds one meaning unless a shift is explicitly marked, which is the rule its flags are judged against.
It holds a single *term constant and watches its meaning slip; it does not run the pairwise contradiction_and_tension_log that tests whether distinct claims are mutually compatible — that is Contradiction Scan's — nor does it draw the claim_dependency_map of how claims support one another, which is Claim-Lattice Mapping's.*

Editorial Notes¶
Form Classification¶
Form family: Assessment, Review & Assurance
Rationale: Term-Stability Review operates as a bounded evaluation of existing evidence or work that produces a finding or disposition because it pins each load-bearing term to a single definition and tracks it through the whole narrative, flagging the passages where a word quietly changes meaning to keep an argument alive — semantic drift used to dodge a contradiction.
Independent corroboration: The frozen evidence defines Term-Stability Review as 'Pins each load-bearing term to a single definition and tracks it through the whole narrative, flagging the passages where a word quietly changes meaning to keep an argument alive — semantic drift used to dodge a contradiction', so its operative form is Assessment, Review & Assurance.
Nearest alternative: Analysis, Modeling & Optimization — Term-Stability Review includes features of an analytical, modeling, inference, comparison, or optimization procedure that derives insight or a solution, but its defining operation is a bounded evaluation of existing evidence or work that produces a finding or disposition.
Review outcome: Independent reviewer agreement; medium confidence.
Origin Attribution¶
Primary origin: Linguistics & Semiotics
Origin pattern: Convergent development
Present-day reach: Universal
Rationale: The defining operation is: Pins each load-bearing term to a single definition and tracks it through the whole narrative, flagging the passages where a word quietly changes meaning to keep an argument alive — semantic drift used to dodge a contradiction. In the linguistics_semiotics lineage, that operation is specifically evidenced by authoritative or primary work that grounds concept definitions, term assignment, consistency, equivalence, and cross-system terminology alignment. This makes linguistics_semiotics the best historical origin, while the retained alternates document contributing methods and later applications rather than being mistaken for coequal origins.

Review resolution: The blind reviewers disagree on primary lineage (organizational_management versus linguistics_semiotics), so I adjudicated the mechanism rather than inheriting either label. The defining operation is: Pins each load-bearing term to a single definition and tracks it through the whole narrative, flagging the passages where a word quietly changes meaning to keep an argument alive — semantic drift used to dodge a contradiction. In the linguistics_semiotics lineage, that operation is specifically evidenced by authoritative or primary work that grounds concept definitions, term assignment, consistency, equivalence, and cross-system terminology alignment. This makes linguistics_semiotics the best historical origin, while the retained alternates document contributing methods and later applications rather than being mistaken for coequal origins. The cited ISO 704 Terminology work — Principles and methods directly supports the mechanism-specific operation and its disciplinary lineage. I retain all independently explained historical alternates without a numeric cap. origin_mode=convergent records how the mechanism arose; domain_reach=universal separately records how broadly it can now be applied.
Encyclopedia synthesis: The exact catalogued form synthesizes established practice rather than reproducing a single standard historical label.
Review outcome: Researched adjudication after independent review; high confidence.

Notes¶
[n1] The motte-and-bailey, named by Nicholas Shackel, is a rhetorical move in which a speaker advances a strong, contentious sense of a term (the "bailey") but retreats to an easily-defensible sense (the "motte") when challenged, trading on the shared word to blur the two. Term-Stability Review is the direct countermeasure: pin the term to one declared sense and every switch between motte and bailey shows up as flagged drift. ↩
