rt-mixed-orchestration
The groupant beside tools/roundtrip/src/mixed/mod.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

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.

Prospective epoch
2026-10-31 source review predicted: owner selects first largest positive byte overlap. Run.merge adds counters/maps and caps failures at4. volume routing branches into English annotation, Hebrew cache/model path, or token-only Text; frames join through link rename/world and inverse rename. Exact checks retain first mismatch. Helpers diff/tally/report join these structures independently. Resource model: Owner O(spans); merge O(entries log keys+example bytes). Whole volume includes external inference, frame/world work and cached parse allocation, not assigned a fictitious constant bound. 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; six 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.
Finite synthetic helper evidence only; live corpora, parser/model loading, full orchestration and filesystem failure races excluded.
approximant
Forward relation
owner selects first largest positive byte overlap. Run.merge adds counters/maps and caps failures at4. volume routing branches into English annotation, Hebrew cache/model path, or token-only Text; frames join through link rename/world and inverse rename. Exact checks retain first mismatch. Helpers diff/tally/report join these structures independently.
Domain: Sorted valid byte spans, aligned stream/gold rows, valid item/var indices and caches; bounded sums. End-to-end context includes models and is not executed. parse_cores can call annotate four times with three 600-second sleeps despite prose saying three times at most.
invariant
Invariant and cost
Invariant
Sorted valid byte spans, aligned stream/gold rows, valid item/var indices and caches; bounded sums. End-to-end context includes models and is not executed. parse_cores can call annotate four times with three 600-second sleeps despite prose saying three times at most.
Cost
Owner O(spans); merge O(entries log keys+example bytes). Whole volume includes external inference, frame/world work and cached parse allocation, not assigned a fictitious constant bound.
Limits
Finite synthetic helper evidence only; live corpora, parser/model loading, full orchestration and filesystem failure races excluded. 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
owner selects first largest positive byte overlap. Run.merge adds counters/maps and caps failures at4. volume routing branches into English annotation, Hebrew cache/model path, or token-only Text; frames join through link rename/world and inverse rename. Exact checks retain first mismatch. Helpers diff/tally/report join these structures independently.
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
Excluded: token-only route establishes parsed semantics or persistent learning; first mismatch cannot be overwritten by later mismatch. owner excludes zero overlap.
reverse_reconstruction
Run totals admit multiple volume partitions and first-four failure tails. Exact reconstruction needs per-layer residuals and original model/cache context; report numbers cannot recover it.
overlap_tie
Equal positive overlap keeps first span; overlap is bytes rather than scalar/token counts.
tagged_routes
En,Heb,Text are alternatives; no pipeline En->Heb->Text exists.
failure_order
Missing Hebrew cache errors before reconstruction; main writes sampled streams before loading annotator.
effect_boundary
parse_cores mutates cache before final dump write; write failure is not rollback and real annotation remains unexecuted.
tests
Checks and evidence
Named source/helper checks: mixed::wave32_tests::owner_and_run_merge.
Wave32 on2026-10-31:10 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. Five 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-wave32-rt_mixed-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.
Finite synthetic helper evidence only; live corpora, parser/model loading, full orchestration and filesystem failure races excluded.
