Elamur Groupantsworld-schooltools-lint-space-normalization
The groupant beside world/src/schooltools.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 source model | forward |
| ast | partial | ../../syntax.json |

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.

Model text
Wave34, 2026-10-31. Source-bound helper model; no universal proof or approximation-error certificate. Historical parent epoch remains intact.
forward
Split on literal newline including trailing empty segment. Each recognized option line rebuilds original leading indentation, trimmed key, colon-space, trimmed fields joined by space-bar-space, and original terminal CR if present. Nonoption lines are copied. Rejoin with newline.
invariant
Newline segmentation and final newline presence persist; nonoption bytes persist. Option punctuation/words and field order persist after trim normalization, but whitespace around colon/fields is intentionally changed.
cost
O(B+F) plus rebuilt output allocation; vectors of lines and fields use O(B+F) total storage.
composition
lint with fix=true writes normalized bytes before computing findings; this pure helper has no I/O. Normalization does not remove internal tabs or fix semantic/duplicate errors. Parser and rebuild must share original line indentation.
behavior-complement
Exclude modification of nonoption lines or disappearance of a final newline. Exclude a semantic option reorder or removal of a star by spacing repair. Whole-file CRLF is not forced on mixed-line input.
reverse-reconstruction
For normalized y retain all original texts with identical newline segmentation, nonoption bytes and same trimmed option fields/key/indent/CR. Space counts around separators and field ends cannot be reconstructed from y.
line_endings
Terminal CR is preserved per recognized original line; splitting on newline retains the empty final segment, distinguishing newline-terminated and unterminated texts.
normalization_fixedpoint
On parsed option syntax with stable indentation and terminal CR, applying the same rebuild twice yields identical bytes. This does not imply lint-clean.
tally_preservation
Canonical option scalar strings are unchanged by outer spacing normalization, so tally agrees before/after on the supported fixture domain.
report_order
In lint orchestration, a successful fs::write can survive a later file failure. Pure fix_spaces proves nothing about durability or multi-file rollback.
checks
Exact world library selections: schooltools::tests::fix_spaces_changes_spaces_only, schooltools::wave9_models::parser_canonical_fibers_and_tally. Current repeated debug/release outcomes and compiled controls are in the root sidecar wave34-evidence.md. Only these supplied-input tests are current evidence; older parent module-wide receipts are historical. Macro bodies remain opaque.
epoch-memory
Prospective model saved before edits. This epoch deepens one existing node rather than renaming it. Production implementation unchanged; tests add helper-boundary observations where stated. No live lessons, frozen suites, model loading, teacher or network. Read-only symbolic relations are broader than the finite native domain.
