feat(futures): prepare known-at individual-contract inputs - #128

Record the installed wheel/sdist consumer versions and the incompatible published Engineer boundary. Add a regression that retains a wholly null input session instead of compressing its clock.

Closes #117

…tinctions

Reproduce naive New York instants shifted to UTC incorrectly and preserve them through bounded disk reads. Keep source NaN distinct from null across price panels and retain pandas label timezones. Validate bad timezone metadata before replacing source generations.

Refs #117

…lity

Keep axis identity and native schema metadata serializable without Arrow as a runtime requirement. Exercise an actual pandas Parquet round trip retaining absent observations, nulls and source dtypes. Document the native panel APIs and remove unqualified storage timing claims.

Refs #117

Retain source terms, availability and unknown coverage without broker effects. Keep imported factor definitions explicit and reuse shared feed declarations. Refs #118.

…tor provenance

Add an offline CSV-to-disk workflow, explicit unknown-term coverage and destination-ID validation. Reject reserved factor output fields rather than silently overwrite their source method. Public workflow regression fails on e58be69 and passes after repair. Seven producer controls cover accepted premises. Closes #118.

Keep stable IDs separate from renamed or reused tickers. Select actual known-at revisions, enforce half-open intervals without rounding nanoseconds, and retain original membership provenance. Refs #119.

Expose the existing private factor-producing operation for causal history preparation without changing split/dividend definitions, validation or public defaults. Refs #119.

Select actual available source revisions and explicit raw/split/total-return bases. Preserve missing observations, share units and consumer field mappings. Use canonical session assignment for overnight label cutoffs and authoritative closes before native dividend factors. Keep the owning history batch open for identity integration, supplied-factor history and final qualification. Refs #119.

Select source factor revisions and their declared share basis without recomputing vendor or merger research factors. Preserve source provenance and unknown retrospective availability, reject causal gaps and conflicting methods, and keep broker consideration unavailable. Refs #119.

Resolve squash-ancestry-only conflicts by retaining the existing qualified action code and guide. Main has the exact bfc source tree; the resolved merge tree is byte-identical to existing3947654. Preserve both histories and require fresh main-head hosted checks.

Preserve the existing history source tree while incorporating the qualified prerequisite history. No source behavior change.

…ppings

Retain captured display symbols while normalizing to source stable IDs. Reject ambiguous venue/lifetime mappings and output collisions before returning a result. Causal history ignores unavailable future price revisions before identity resolution and retains matched identity provenance. Related focused history,registry,assets,storage and adjustment checks:271 ResourceWarning-clean passes.

…ssions

Reuse canonical batched session assignment when instant observations meet dated session identity intervals. Require captured ex-date close currency to match cash and price units. Retain actual failing public-input controls and typed-empty coverage;274 focused ResourceWarning-clean checks pass.

Retain pre-entry observations,source identity intervals and known-at revisions through actual CSV storage. Add supplied-factor causal-basis,units,coverage and immutable-source regressions and document native versus imported definitions. Seven producing-code failure controls cover the accepted premises without waivers. Full final-revision and installed consumer qualification remains required before closure.

Actual finite CSV terms can overflow under reciprocal or rational normalization,or underflow to zero. Validate the canonical ratio after normalization before publishing event facts. Three public-input regressions fail on5a4b and pass with the guard;134 focused adjustment/handoff ResourceWarning-clean tests pass.

Preserve all dated history work and incorporate the prerequisite's three source-ratio overflow/underflow regressions. Combined focused history,identity,assets,action,storage and conversion checks pass with ResourceWarning errors.

…cation

The native dated registry,source revision,raw/split/total-return and supplied-factor workflows retain source keys and missingness. Frozen history source passed4336tests per native/ResourceWarning lane and both installed artifacts passed actual public Engineer/Diagnostic consumption. The combined action-ratio repair passes288focused tests and all seven dated producer failure controls. Final current-head hosted main gates and artifact identity remain required before merge. Closes #119.

Actual captured source workflows preserve pre-event cash terms while converting the derived share basis,and retain the universe known at the earlier cutoff. Each regression passes correct code and fails its producing-operation violation. No runtime source change.

First bounded native preparation uses captured source-file loaders,dated registry mappings and existing lagged roll algorithms. Keep raw bars and separate metric publication eligibility,stable selection IDs,paired raw marks and explicit price units. Four public workflow tests cover native builder agreement,delayed OI,future revisions and missing old legs;470 focused canonical ResourceWarning-clean regressions pass. Further lifecycle,unit,edge and installed qualification remains under issue120;this checkpoint does not claim completion.

Source-file workflows reproduced ignored actual notice dates and a constructor calendar overriding the receiving API. Reuse scheduled offset logic with actual dates and copy native policies onto the selected feed calendar without mutating callers. An existing native zero-offset regression also failed because0became25;unknown offsets alone retain that fallback. Preserve raw cents and dimensionally correct normalized multipliers,and record policy parameters.476 canonical focused ResourceWarning-clean checks pass,plus10current preparation checks. Not final issue120 qualification.

A real captured price correction suppressed previously available OI and changed the current contract. Preserve eligible captures until each metric selects its own publication revision;price output still selects the latest known price. Keep source capture lineage,distinguish explicit metric revisions from repeated unchanged facts,and allow genuinely unknown optional OI without inventing values. Both actual source regressions fail90b and pass with the repair;482canonical focused ResourceWarning checks pass.

Retain the existing27fca source tree byte-for-byte while reconciling squash-only ancestry conflicts. Preserve both histories and require fresh final main-head hosted/package identity gates.290focused ResourceWarning tests and strict docs pass again.

Preserve the808c source tree exactly while incorporating the main-reconciled history prerequisite. No runtime or test behavior change;future final main-head gates remain required.
