# Task Ledger — first release

Updated 2026-09-11 for Codex-ytr83r. The full
[user goal](../PROJECT_GOAL.md) and [current progress](STATE.md) remain authoritative.
[Exact host ledger archives](history/2026-09-11-ytr83r-integration/README.md)
preserve prior facts, dates and reasoning without transferring their acceptance.

## Goal and given requirements

Deliver a complete, usable OA/SA release on Windows and Linux, with one explicit
reST semantic contract and equivalent graphical, textual and REST access. Include
constraints/calculations, quantities/units, maintained libraries, behavior/state,
traceability and navigable offline help. Reduce cognitive load and visual clutter;
small and large models must be practical using text alone. Later Arcadia layers
remain future scope. Compilation or a pleasant happy path is not completion.
Issue2 further requires consistent direct process/scenario canvas interaction;
the owner's clarification allows domain constraints rather than arbitrary movement.

At15:28UTC on2026-09-11, the user explicitly deferred Linux builds and checking
until they resolve WSL2 networking and instruct resumption. Linux setup/downloads
are paused with inputs preserved. Continue independent Windows work; do not treat
offline preparation as a networking fix or Linux acceptance.

## Verified facts

- Local start was cleanff615d0. Root decoded/hash-verified/imported published3978,
  c6 and4bb bundles; merged c6 as c81e285 and integrated creation4bb at e207b04. There were
  no production cherry-pick conflicts; docs/attributes require evidence union.
  The current goal is copied from the user's latest file.
- Read-only integration comparison finds equivalent workspace/Sensor code in c6;
  replaying3978 or d114 is unnecessary. Core source is unchanged betweenff andc6.
  B4 now has a production Scene bridge and independently reviewed source, with
  focused lifecycle22/22 and full desktop675/675 passed on source2908405. The
  ordinary GUI build and real OA/SA lifecycle matrices now ran; OA full name-only
  Save/Undo/Redo/reopen and the corresponding SA workflow passed exact independent
  comparisons. Corrected workspace/all-targets strict Clippy also passed0;
  Unicode appearance remains open. See the
  [native record](release-lifecycle-native-ytr83r-20260911.md) for exact scope.
- Imported source implements named behavior creation, exact prepared-batch
  correlation, success-only selection, raw-draft guards, recoverable original
  layer and modal-priority Escape. These are source facts; combined local runtime
  acceptance is pending.
- Earlier-host desktop642 and653 suites, scoped native scenarios/creation,
  packaging25 notices and source experiments retain exact attribution in
  [STATE.md](STATE.md). They are not new local passes.
- The original transferred creation oracle incorrectly equates physical disk files
  with reachable sources during Undo. Later external v2 corrects the evaluator
  with explicit origin/retained-byte rules; exact v2/evidence2ec was imported at
  b853a1e after complete path/hash preflight. New host execution is still pending.
- Isolated Rust1.98.1/LLVM23.1.1 and locked dependencies are available. Packaging
  11/11 and synthetic Windows notice checks pass. Current core all-targets passed
  433 tests; its optional inheritance probe separately passed with slow debug
  timings that require controlled optimized interpretation. Focused lifecycle
  passed22/22 after two installed-Iced API corrections; full desktop passed675/675.
  Strict reST/HTML generation passes with Docutils0.22.2.
- B4 independent criticism found and resolved self-caption overlap and two dense
  minimum-Fit hit-selection counterexamples. Shared nearest marker/message-stroke
  arbitration preserves exact marker/header/label selection. Ten real-Scene tests
  and two clip geometry tests passed in the22-test focused gate. The independent twelve-scenario native oracle passed compile,
  admission, self-check and exact baseline/name-only predictions before GUI output.
- The separate baseline-context experiment passed218 assertions; explicit
  one-level overrides reduce repeated stable assumptions while complete frozen
  definition environments remain necessary. Proposed syntax is not source7.
- After the user's virtualization/reboot change, supported Ubuntu26.04 install
  completed exit0 and a real x86_64 WSL2 kernel shell completed. Later VM startups
  timed out before apt. Owner328's exact VirtioProxy configuration now supports
  a persistent root shell, but requested IP/DNS/HTTPS checks failed. Signed offline
  dependency preparation advances without host VPN inspection or changes. This
  establishes guest execution, not Linux builds or GUI acceptance; exact outcomes are
  in the [WSL record](release-wsl-postboot-ytr83r-20260911.md).

## Assumptions and unresolved questions

- Combining already coherent desktop slices should preserve behavior; fresh build,
  automated and native gates must test that assumption.
- The baseline/library designs can fit existing atomic Project/Command/source
  boundaries; exact references, deletion, transition, imports, freezing and
  numeric rules still need ratified contracts and falsification.
- Pinned package provenance must be distinguished from checked type compatibility;
  unchanged quantity kinds cannot become incompatible merely through cosmetic
  repackaging without a deliberate policy. Energy and Torque remain distinct.
- Ubuntu26.04/WSL2 is the current supported Linux route; reliable repeat startup,
  guest toolchain/dependencies and GUI/service/package execution remain open.
  Initial shell success does not erase later startup timeouts. Old QEMU work is
  retained as history, not the next route to repeat.
- Large-model human/AI task usability, cross-file refactoring, actual chooser
  latency/keyboard/minimum geometry and complete native lifecycle behavior remain
  to be measured. Parser admission or a widget experiment is insufficient.

## Candidate designs and selected directions

The imported [analysis proposal](release-analysis-semantics-design-20260910.md),
[library proposal](release-libraries-semantics-design-20260910.md),
[paired critique](release-semantic-proposals-review-20260910.md) and
[textual authoring design](release-textual-authoring-design-20260911.md) retain
alternatives and counterexamples. Metadata-only analysis and bare source includes
do not meet evaluated quantities or maintained libraries.

Codex-956atf root selected property-owned baseline values/formulas with explicit
ModelBaseline/Case evaluation and one-level case overrides for contract refinement.
No hidden default case or UI-dependent evaluation; inherited formulas use the
effective requested case, and complete freeze captures definitions/provenance.
Exact numeric, library normalization/type compatibility and transition details
remain open. This direction is recorded in [DECISIONS.md](DECISIONS.md), not silently
treated as completed production semantics.

The external staged prerequisite design reserves source/consumer identities,
keeps the parent context/rawtext/slot, stages locally and creates source+consumer
in one atomic final command. It must not implicitly allocate work, involve
capabilities, retarget an Exchange-fixed endpoint or accept a different editor.
Qualified Action allocation remains a distinct engineering choice.

## Retained implementation decisions

- Keep one authoritative typed Project, validated atomic Commands, stable
  identities and explicit references. Semantic ownership/allocation/order and
  diagram geometry remain distinct; forms are adapters, not a second metamodel.
- Preserve source ownership/comments/includes and exact model/source history.
  Writeback succeeds before adoption. Invalid/rejected raw drafts survive and
  browsing/tool selection does not silently accept another editor. Recovery
  validates/replans rather than trusting serialized commands.
- Semantic reconciliation uses finite typed facets, frozen baselines, explicit
  mappings and one atomic candidate. Names alone never establish identity.
- OA↔SA transitions are explicit engineering decisions. New persistent semantics
  need validation/reference/deletion/transition/source/API/UI/history parity.
- Exact evidence bytes and host attribution survive integration. No focused
  test total is added to a full-suite count; old binary acceptance does not
  transfer to newly merged code.

## Current strategy and coordination

Root owns local integration, serialized builds, native inputs and final synthesis.
The local audit resolves evidence and reviews source; independent server review
has its own report. Codex-9e8r6t owns staged sources/first actions and source CLI;
Codex-956atf owns chooser, semantic contracts and the shared canvas design. Read Gitea issues #1/#2 and Wiki before
resuming, obtain exact coherent transfer heads, and respect their source ownership.

First finish and verify the integrated current source using the imported corrected
evaluator and newly prepared independent lifetime oracle. Then close remaining modeling/textual,
analysis/library and platform gates with independent criticism and whole-task
acceptance. Update facts, assumptions and decisions as evidence changes them.
