# macula-tanakh

The groupant beside tools/macula/src/tanakh.rs in the Mova repository: what the code computes, what it never does, how to go back from its outputs, its invariants, cost and checks.

## Facts

- **kind:** groupant
- **status:** partial source bound model
- **source:** [`tools/macula/src/tanakh.rs`](https://github.com/ElamurAI/mova-free/blob/main/tools/macula/src/tanakh.rs)
- **source SHA-256:** `fc1c2896a6fcedfa…`
- **repository folder:** [`tools/macula/src/tanakh.rs.groupant`](https://github.com/ElamurAI/mova-free/tree/main/tools/macula/src/tanakh.rs.groupant)
- **repository commit:** `855da7bd4a7b`

> **Implementation material.** A Mova code model describes this code at one source revision: partial models, finite checks and their stated scope. It is not a reviewed general exposition, and its labels are shown as written, never raised.

## Components

| component | label | where |
|---|---|---|
| **approximant** | partial | [approximant](#approximant) |
| **ast** | partial | `syntax.json` |
| **composition** | partial | [composition](#composition) |
| **cost** | symbolic source derived | [invariant](#invariant) |
| **descriptant** | present | [descriptant](#descriptant) |
| **invariant** | partial | [invariant](#invariant) |
| **tests** | executed bounded checks | [tests](#tests) |

## Obernants

The typed relations around the forward model: the behaviour complement (what the code never does), the reverse reconstruction (every input compatible with an output) and specialised views.

| id | type | label | where |
|---|---|---|---|
| `behavior_complement` | behavior_complement | partial source derived model | [behavior_complement](#behavior-complement) |
| `reverse_reconstruction` | reverse_reconstruction | partial source derived model | [reverse_reconstruction](#reverse-reconstruction) |
| `licence_order` | licence_order | partial source derived model | [licence_order](#licence-order) |
| `sparse_coordinates` | sparse_coordinates | partial source derived model | [sparse_coordinates](#sparse-coordinates) |
| `book_transport` | book_transport | partial source derived model | [book_transport](#book-transport) |
| `union_multiplicity` | union_multiplicity | partial source derived model | [union_multiplicity](#union-multiplicity) |

## Model text


### descriptant

#### Descriptant

##### Prospective epoch

2026-10-31 source review predicted: edition parses JSON, exact Public Domain admission, then chapter/verse strings through html_text/NFC retaining sparse coordinates. targums writes declared layers/provenance. by_verse appends ids per whitespace verse; index unions three maps/tagged Targum refs, sorts Tanakh order, skips unknown books, writes per-book TSV. Resource model: Edition O(B); R records,V verses,F files: maps O(R log V), files O(F log F), union O(V log V), memory O(R+output). No real filesystem benchmark. External prospective.md predates test additions and preserves APIs, effect order, hazards and interaction hypotheses.

##### Observed epoch

Bounded real helper checks in tests.md constrain these models; syntax is a partial lexical projection with no macro expansion, name resolution or proof. Production expressions unchanged; five inline test modules added. Compiled mutants are temporary and exactly restored. Existing malformed-input and nonfinite domains remain explicit, not silently repaired. Parent composes this scope with siblings without adding overlapping costs twice.

Edition/order helpers tested; filesystem outputs unexecuted.

### approximant

#### Forward relation

edition parses JSON, exact Public Domain admission, then chapter/verse strings through html_text/NFC retaining sparse coordinates. targums writes declared layers/provenance. by_verse appends ids per whitespace verse; index unions three maps/tagged Targum refs, sorts Tanakh order, skips unknown books, writes per-book TSV.

Domain: Licence precedes text shape validation; empty/nonstrings omit without renumbering. Missing sources empty, duplicate ids retained. Book order differs from library. Writes partial/nontransactional.

### invariant

#### Invariant and cost

##### Invariant

Licence precedes text shape validation; empty/nonstrings omit without renumbering. Missing sources empty, duplicate ids retained. Book order differs from library. Writes partial/nontransactional.

##### Cost

Edition O(B); R records,V verses,F files: maps O(R log V), files O(F log F), union O(V log V), memory O(R+output). No real filesystem benchmark.

##### Limits

Edition/order helpers tested; filesystem outputs unexecuted. No percentage surrogate is implemented: categorical parsing/effect observations lack an admitted numerical error metric. Any future profile must define its metric/domain and use only1/2/5/10 percent caps.

### composition

#### Local composition

edition parses JSON, exact Public Domain admission, then chapter/verse strings through html_text/NFC retaining sparse coordinates. targums writes declared layers/provenance. by_verse appends ids per whitespace verse; index unions three maps/tagged Targum refs, sorts Tanakh order, skips unknown books, writes per-book TSV.

Children select narrow source functions with their exact byte intervals. Remaining branches stay in the file model; fragments are not exhaustive partitions. Calls and state joins follow the forward relation, not folder order. Shared scans/helpers are counted once in whole-file costs. Complement of composition is not union of complements; reverse composition retains compatible intermediates and caller premises.

### models

## Typed source-bound relations

Subject: exact source SHA-256 in manifest. Domain and resource premises are in invariant.md. Each model is partial, source-derived, over a single helper invocation or the described finite trace. Complements are proposed inner exclusions under those premises; reverse relations retain all compatible antecedents, with no unique inverse claim. The oracle is the named checks in tests.md; unexecuted cases remain hypotheses. No numerical approximation certificate.

### behavior_complement

Non-PD cannot yield copied verses. Unknown book not written by index. Missing translation cannot remove verse present elsewhere: union, not intersection.

### reverse_reconstruction

Output allows removed markup/empty positions compatible with retained ids and ignored metadata. Index row allows inputs yielding same ordered id lists; missing versus empty files indistinguishable.

### licence_order

Bad JSON parse first; valid JSON wrong/missing license fails before text shape. Exact case-sensitive Public Domain admission.

### sparse_coordinates

Emit BOOK.(i+1).(j+1) for nonempty cleaned strings; no compacting, nonarray chapter empty.

### book_transport

Tanakh key Torah/Prophets/Writings vs MACULA ordinal. Code-based remap required; unknown key39.

### union_multiplicity

by_verse preserves occurrence duplicates; Targum refs tagged. All-three counts field presence, not semantic alignment.

### tests

#### Checks and evidence

Named source/helper checks: tanakh::tests::public_domain_only, tanakh::tests::tanakh_order.

Wave31 on2026-10-31:30 distinct exact tests passed twice debug and twice release, with equal sorted named outcomes. This node claims only its listed subset; empty subset means source review only. Six actual source-behavior mutants compiled, failed assertions, restored exact bytes/hash, and passed focused green reruns. No assertion-only mutants; existing swapped-input controls are separate. Receipt bundle: $MOVA_DATA/runs/octopus-wave31-corpus-2026-10-31 (native-commands.json, source-test-map.json, mutation-results.json, *.status/*.log). No live corpus, teacher, frozen assessment, download or production data used.

Edition/order helpers tested; filesystem outputs unexecuted.
