# world-triggers-determinant

The groupant beside world/src/triggers.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_fragment
- **status:** partial source derived instance
- **source:** [`world/src/triggers.rs`](https://github.com/ElamurAI/mova-free/blob/main/world/src/triggers.rs)
- **source SHA-256:** `4eea913faafa8f76…`
- **covers:** Logical source region "/// The determinant" through before "/// The sentences". First numeric word in 1583..9999 is inspected only when whole-word leap or year occurs. Gregorian leap predicate is divisible by 4 except centuries unless divisible by 400. Clock fires on now/today or substring what time; local seconds = now as i64 + 3600*tz. Test domain keeps arithmetic in range. Recall uses first supplied matching event, fixed EVENTS order, lowercased alphanumeric words with optional trailing s, and saturating age. Future timestamp yields zero age; nonpositive elapsed duration omits took. All histories differing after first matched event remain compatible. Time quantities carry seconds multiplier; frequencies carry cycles/second. First numbered frequency times first numbered duration yields cycles; without duration the period is reciprocal frequency. Target conversion uses first unnumbered duration unit and sum of all numbered durations. Mean month/year seconds are fixed constants, not civil interval lengths. Parent composition retains shared text/clock/intermediate values. Full-file wrapper and test gaps remain in the root. (bytes 13289–16102)

> **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.

### Forward

Logical source region "/// The determinant" through before "/// The sentences". First numeric word in 1583..9999 is inspected only when whole-word leap or year occurs. Gregorian leap predicate is divisible by 4 except centuries unless divisible by 400. Clock fires on now/today or substring what time; local seconds = now as i64 + 3600*tz. Test domain keeps arithmetic in range. Recall uses first supplied matching event, fixed EVENTS order, lowercased alphanumeric words with optional trailing s, and saturating age. Future timestamp yields zero age; nonpositive elapsed duration omits took. All histories differing after first matched event remain compatible. Time quantities carry seconds multiplier; frequencies carry cycles/second. First numbered frequency times first numbered duration yields cycles; without duration the period is reciprocal frequency. Target conversion uses first unnumbered duration unit and sum of all numbered durations. Mean month/year seconds are fixed constants, not civil interval lengths. Parent composition retains shared text/clock/intermediate values. Full-file wrapper and test gaps remain in the root.

### Invariant

Respect source order, retain ambiguity of lossy text projections, and keep observed finite correspondence distinct from universal semantics. Pure functions have no modeled filesystem effects. Error paths before annotator acquisition do not write the output.

### Composition

Compose only through equal intermediate token sequences, paragraphs, quantities, event lists and explicit clock inputs. Parent roots cover every logical source region, including imports/constants and native tests; local fragments isolate useful operations and may overlap. The hierarchy is not a complete call graph. Same numeric answer does not imply same text or event history.

### Cost

Tokenization O(text bytes); quantity lookup O(words * units); recall O(EVENTS * words * hooks + lived scan); expectations O(events + sum group gap-sort costs); log reads O(file bytes), overlap O(manual bytes + candidates log candidates). Costs are symbolic operation/allocation counts, not measured speedups.

### Limits

Partial syn-2 syntax is source-bound; no macro expansion, semantic AST, name resolution or verified dependency behavior. No automatic reverse solver or production surrogate exists. Poly annotator acquisition/tokenization, detokenization, output encoding and filesystem failures beyond early rejection remain conditional. Trigger talk::civil/now/tz_offset, state::root, global nerves graph, manual data and stdout are dependency boundaries. No activate/Task/drop/fire/episodes/expectation/explain calls are made by the new bounded tests. Extremely large counts, nonfinite floating values, signed timestamp overflow and concurrent log append/read remain outside tested domains. Declared event effects are not executed.

### Epoch memory

2026-10-30 prospective: punctuation continuation should preserve a total token partition; malformed Gutenberg ordering should return Err before the parser. The old slice admitted a reversed-bound panic; the repair adds the ordering guard and isolates pure extraction without changing public signatures. Calendar century exceptions and expectation upper medians are predicted separately from natural-language semantics. Native tests and mutation controls calibrate these claims; see tests.md. Formal proofs and general corpus quality remain absent.

### catalog

## world-triggers-determinant

Domain: Finite English texts, finite positive unit quantities, year domain 1583..9999, in-range explicit u64 clock/i64 timezone, bounded event histories; named external log/graph/manual effects are conditional only.

All relations below are source-derived partial models, conditional on successful allocation and the stated input domain. U is the product of admitted inputs and observations (returns, errors, and explicit effects). R is the declared forward relation. Complement entries are candidate inner bounds of U minus R, not complements certified from an approximate emulator. Converse relations preserve every compatible antecedent; no unique original text or history is claimed.

### nonbehavior

In the bounded domain exclude a calendar answer outside years 1583..9999 and a recall without a matching lived event. Clock and recall order follow dispatch, not chronological sorting.

Scope: Finite English texts, finite positive unit quantities, year domain 1583..9999, in-range explicit u64 clock/i64 timezone, bounded event histories; named external log/graph/manual effects are conditional only. Fixed code and dependency contracts; evidence in tests.md. This is a conditional source relation, not a general proof. The explicit native fixtures are falsifiable observations; untested I/O schedules remain gaps.

### antecedents

For a fire_at result retain all input tuples satisfying quantity, clock, calendar and recall predicates simultaneously; independent inverse projections must share the same original text and explicit clock, so their Cartesian product is too broad.

### tests

#### Bounded native evidence

Commands: cargo test -p world --lib bounded_models -- --test-threads=1; repeat with --release. New native modules contain five tests per source, including a compiled wrong-model discriminator. Independent finite tables cover partition, headings, malformed extraction, units, Gregorian dates, explicit UTC civil time and event ordering; enumeration covers 1,555 token sequences through length four and 85 unit quantities. The poly public rejection fixture creates a fresh scratch directory and preserves a sentinel output. No live hot-state access or parser acquisition is exercised.

External mutation controls remove the marker-order guard and replace the Gregorian century predicate, then compile and run the corresponding native tests; both must fail, after which originals are restored. Debug/release logs are normalized to sorted bounded test outcomes and compared twice per profile. Syntax projection is generated twice and compared byte-for-byte. Detailed receipts and fingerprints: evidence.json at the file root. These are finite observations, not exhaustive Rust or I/O proofs.
