Paper 01 covers quotation and reference fidelity for English Christian Scripture.

The same requests cross four delivery paths; this is not a model leaderboard.
Central claim
Connecting a source moves failure onto whatever decision the model still controls.
Abstract
People increasingly ask AI assistants for Scripture in sermon preparation, teaching, and pastoral conversation. Someone asking for a passage wants particular words in a particular translation, from a source they could have opened themselves. A reply that blends translations, drops a verse, or paraphrases inside quotation marks can appear correct while giving the wrong text, and the person who asked is often the one least able to tell. Many evaluations do not isolate this failure: a response can be factually accurate, properly cited, and semantically faithful yet still fail as a quotation.
When the words themselves are the answer, who should be responsible for them? We routed 8,640 matched requests through four delivery designs across six model families, three open English editions, and twenty passages, and no single design solved the problem. Quoting from memory was least reliable by a wide margin. A lookup tool and a deterministic renderer closed most, but not all, of that gap. Connecting a source did not remove failure; it relocated failure to whatever decision the model still controlled. Models sometimes asked a tool for the wrong passage, and sometimes altered exact text placed directly in context. Once the correct reference reached a non-generative renderer, exact text survived in 99.90% of cases; end-to-end performance was lower because the model could still choose the wrong passage. Exact quotation is therefore a chain: select the passage, reach an authorized copy, preserve its words, and deliver them intact. Each link must be checked separately because one aggregate score cannot identify which link failed. We measure delivery only, not whether a passage was well chosen, rightly interpreted, or pastorally appropriate.
Source-delivery chain
Exact delivery succeeds only when all four responsibilities succeed. The study changes who owns each responsibility, then observes where failure moves.
Identify the intended work, edition, passage, and exact span.
Reach an authorized, versioned source of record for that selection.
Reproduce the source text exactly, without blending or paraphrase.
Preserve the exact text through the final user-visible output.
Exact delivery = S × A × R × D
Primary result
Exact delivery requires strict final-text equality and condition-specific evidence that the declared delivery path was followed. The four conditions assign different responsibilities, so their rates describe staged systems—not equal-burden treatment arms.
The model selects, recalls, renders, and delivers the passage from parametric memory.
Baseline
vs. memory
540 / 2,160
95% CI 23.22–26.87%
This is a best-case copy test: the requested passage and edition are already supplied, so the model only has to preserve them.
+68.61 pp
vs. memory
2,022 / 2,160
95% CI 92.50–94.57%
The model decides whether to call a source tool and which edition and span to request.
+55.09 pp
vs. memory
1,730 / 2,160
95% CI 78.36–81.72%
The model selects a structured reference; non-generative code inserts the source text.
+66.25 pp
vs. memory
1,971 / 2,160
95% CI 89.98–92.37%
Intervals are descriptive observation-level Wilson intervals. The target-cluster bootstrap intervals for paired differences were +61.71 to +75.60, +46.48 to +63.47, and +58.47 to +73.98 percentage points. They describe variation across the fixed 20-target panel and do not support population inference to all passages, models, editions, or requests.
What the aggregate hides
The remaining errors clustered around the decisions still left to the model. That distinction matters more than choosing a single winning architecture.
6.39%
Source supply removed selection and retrieval, yet 138 responses still failed exact preservation.
95.00% → 84.17%
Models invoked the lookup tool 2,052 times, but requested the expected edition and span only 1,818 times.
99.90%
Once the expected reference reached deterministic code, 1,971 of 1,973 outputs were exact.
Failure migration
A tool can make authoritative text available without guaranteeing it will be used. A renderer can guarantee the bytes it emits without guaranteeing the model selected the right source. A final-output check is needed to establish what the user received.
| Delivery path | What it secures | What remains exposed |
|---|---|---|
| Source supplied | Selection + access | Generative preservation |
| Lookup tool | Authorized access | Delegation, selection, rendering |
| Deterministic insertion | Rendering + replacement | Reference and span selection |
Prompt form
Explicit-reference prompts named the passage. Contextual descriptions required the system to infer the intended reference from an event or description before quotation could begin.

Edition and passage effects
Requested edition
Memory-based quotation reached 41.53% for BSB, 28.47% for WEBU, and 5.00% for LSV. Once a source was connected, the edition gap narrowed sharply. The study establishes an edition interaction in this panel; it does not identify the cause.
Passage length
Exact delivery for long passages was 5.37% from memory, 85.93% with source text supplied, 68.33% with tool retrieval, and 81.85% with corrected deterministic insertion. Even having the source in context did not eliminate omission and alteration.

Study design
The unit of analysis was one target × prompt family × delivery condition × edition × model route × epoch observation. All scheduled observations completed; terminal provider errors remained failures in the denominator.

Strict final-output equality plus evidence that the declared delivery path was followed. Terminal errors count as non-deliveries.
A purposive 20-target, fixed-model, fixed-edition panel. The study does not estimate prevalence across Scripture or products.
The Apologist Project developed and maintains the shared condition implementation and contributed to how the four conditions were operationalized. Fide AI controlled the research question, prospective lock, execution, analysis, evidence custody, release boundary, and claims.
Design implications
These recommendations follow from the source-delivery chain. The framework can transfer to other sources of record, but the measured rates cannot.
01
Distinguish a request for meaning from a request for exact source text.
02
Carry work, edition, span, authorization, and provenance in system state.
03
Let models identify intent; let non-generative components own words that must not change.
04
Test invocation and requested span—not merely whether a tool exists.
05
Verify the user-visible buffer after wrappers, streaming, and transformations.
For Christian institutions
What exactness cannot answer
An exact verse can still be detached from literary context, used to answer the wrong question, or interpreted against a community's commitments. This evaluation removes misquotation as one failure mode. It cannot decide which passage should be used, how it should be interpreted, or what pastoral counsel should follow.
Open research program
FID-056 is deliberately larger than one paper. Three follow-on studies can begin against released data without new model spend; others need construct design and domain expertise.
P02
Data in hand
Why did one route bypass its authorized tool roughly three times in ten while five others essentially always delegated?
P03
Data in hand
Separate genuine passage misidentification from interface non-conformance and study what makes a passage hard to identify.
P04
Data in hand
Investigate the large edition effect without treating it as evidence of training-data membership.
P05–07
Needs collaborators
Extend the program with construct design, scholarly review, source-rights work, and native-language expertise.

The study was internally SHA-256 locked before confirmatory execution. This was not a public registry deposit.
A literal-parser result of 1,813 exact responses became 1,971 after all 2,160 saved deterministic responses were replayed through the corrected parser. No model outputs were regenerated.
Passage text from the evaluated BSB, WEBU, and LSV editions is excluded and disclosed through per-target digests. The separate examples directory contains only declared public-domain KJV wording.

Results apply only to the named routes, run dates, 20-target panel, two prompt families, three open English editions, four delivery conditions, and scoring protocol. They do not establish a ranking of models or vendors, theological correctness, contextual appropriateness, pastoral safety, deployment readiness, training-data membership, licensing compliance, or performance on restricted translations.
