Elamur Groupantstreestore-main
The groupant beside tools/treestore/src/main.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
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 |
| Ast | partial | syntax.json |
| Composition | partial | Composition |
| Cost | symbolic source derived | Invariant |
| Descriptant | present | Descriptant |
| Invariant | partial | Invariant |
| Tests | executed bounded checks | 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.
| relation | type | label | where |
|---|---|---|---|
| Behavior complement | behavior complement | partial source derived model | Behavior complement |
| Reverse reconstruction | reverse reconstruction | partial source derived model | Reverse reconstruction |
Model text
Descriptant
The CLI: train, pack (with resume), verify (byte equality with the source), index, get, sent, bench. Epoch 2026-11-06.
Approximant
Each command is a thin composition of library calls with timing and peak-RSS reports.
Invariant
verify fails (non-zero exit) when any record differs from its source or is missing.
Composition
model::train → store::write → dir::Store::index → get/sent/bench.
Behavior complement
No deletion of sources, no automatic retraining, no multi-shard parallelism of its own (parallel inside a shard).
Reverse reconstruction
Inapplicable: a command's output does not determine its arguments.
Tests
Real-data runs recorded in the README (2026-11-06).
