# First release execution plan

Updated 2026-09-11 for the published Codex-ytr83r B4 source checkpoint.
[PROJECT_GOAL.md](../PROJECT_GOAL.md) defines the full outcome;
[STATE.md](STATE.md) scopes evidence/ownership and
[TASK_LEDGER.md](TASK_LEDGER.md) separates facts from decisions.

## Immediate integration and verification

1. Preserve completed integration c81e285/e207b04/b853a1e and reviewed B4 source
   52f6e17 on codex/release1-ytr83r. Do not replay equivalent3978/d114 changes.
   CLI-only01b76a1 was reviewed and imported as023e3a8 without core/dependency
   changes. Preserve the new AGENTS maintenance instruction and exact goal bytes.
2. Core433, independent lifecycle-oracle admission, focused lifecycle22 and full
   desktop675 passed on this host. Production freeze2908405 is unchanged by
   evidence checkpoint3ade397. GUI build, both-layer history/reopen and corrected
   workspace strict Clippy passed. Finish the affected test and Unicode/native
   workflows below. Do not repeat the passed suites without a
   source change or new finding. Root serializes writers and records exact scope.
3. Use the imported evidence2ec creation-oracle v2 for native Undo comparisons.
   Reject unknown/changed detached files while allowing exact files
   retained from an explicit pre-Undo origin. Preserve full Project and reachable
   SourceBundle equality and original role identities through Redo/reopen.
4. Exercise current Windows UI at minimum/wide sizes: creation name/owner/viewpoint,
   one-step history, stale/raw-draft rejection, first Escape/modal priority,
   recovery, clicked root/ALT action/observation/reuse, exact caller return,
   same-size Fit and natural subsequent scrolling. Use independent semantic
   predictions, not only screenshots or serialization of observed outputs.
5. Review current external Gitea handoffs before importing staged prerequisites,
   empty-state actions, contextual chooser or source CLI. Validate final combined
   workflows and preserve explicit ownership/qualification semantics.
6. After actual B4 test/native acceptance, prepare a distinct runnable Windows
   prerelease with current-toolchain notices and exact executable/source hashes.
   Existing MCP credentials have now completed a scoped branch push and remote
   readback; release attachment upload still needs concrete-artifact verification.
   Codex-9e8r6t retains the earlier named-authoring prerelease ownership.
7. Linux setup/downloads/builds/checking are paused by direct user instruction.
   Wait for the user to resolve WSL2 networking and explicitly instruct resumption.
   Preserve installed Ubuntu, exact VirtioProxy configuration and complete/partial
   offline inputs. Networking remains unresolved; preparation is not Linux
   acceptance. Follow the current WSL/offline records rather than old reboot plans.
8. Incorporate the owner clarification in issue2: process/scenario interaction
   should use consistent direct canvas workflows while preserving domain
   constraints. Codex-956atf owns the shared canvas design; B4 rendering and
   prerequisite forms support it but do not close this requirement.

## Capability milestones

| Outcome | Work and acceptance |
| --- | --- |
| Usable direct behavior/state engineering | Continuous ordered/explicit process authoring, clicked root/nested scenario insertion, exact reuse bindings/caller return, state naming/creation, recovery and source-preserving history. Complete B4 lifetime rendering with actual lifetime bounds, branch-local Delete activation clipping, incomplete lanes and self-arrow endpoints. |
| Precise engineering analysis | Refine property-owned baseline values/formulas plus explicit ModelBaseline/Case one-level overrides. Close quantity kind/unit/value, exact/approximate numerical policy, dependencies/cycles, false/missing/error, complete freeze and definition provenance. Implement coherent validated core/source/REST/GUI/history contracts. An exact-duration slice alone cannot satisfy the full goal. |
| Maintained reusable libraries | Resolve source-only normalization, pinned offline definitions/closure, provenance versus checked same-origin compatibility, source→local instance maps, explicit three-way updates/local divergence, subjectless analysis closure and OA/SA mounted-data transition policy. Demonstrate two projects/two instances, cosmetic and semantic upgrades, conflicts/detach and rollback. |
| Practical complete textual and graphical tasks | Measure small/large text-only creation, cross-file reference navigation, safe alias rename and lossless patch preview. Integrate source CLI and bounded contextual choices; actual keyboard/IME, repeated names, stale events, recovery and minimum geometry must pass. Keep offline guide/examples and normative source documentation aligned. |
| Complete engineering stories | Close OA↔SA transition/reconciliation, typed data/interfaces/state, artifacts, saved views, hosted workflows and tutorial tasks against the full current goal. Confirm parity and precise specification rather than inheriting historical exclusions. |
| Reproducible Windows/Linux release | Current tests/format/strict Clippy, reST/OpenAPI/migration/example gates; real GUI and REST transport/restart/ETag conflict acceptance; matching optimized desktop/server packages, complete notices/archive hashes and clean-runtime launch. Fresh independent requirements/domain/parity/architecture/UX/runtime review resolves material findings before release. |

Milestones run adaptively where independent work helps. Analysis and libraries
share definition/identity assumptions and must converge before broad migrations.
Other-host slices remain coordinated through issue #1 and Wiki. Native/Cargo
leases are host-local; source ownership and exact transfer heads are shared.

## Evaluator boundaries and replanning

Use authoritative source semantics, exact UUID/source preservation and actual
user workflows. Source-only experiments are not accepted new grammar; mounted
widget tests are not native readability; synthetic packaging checks are not
Linux runtime. Preserve old environmental failures as evidence without inventing
current blockers. Continue independent work when platform or transfer work waits.

[Archived prior plans](history/2026-09-11-ytr83r-integration/README.md) preserve
all previous milestone detail. Update this plan when a counterexample changes
the right next action; do not lower completion criteria after substantial effort.
