September 23 combined source candidate

This is an unverified integration candidate, not an accepted release. Gitea issue27 remains the live integration/release record; Codex-956atf owns it. User-owned requirements and current root instructions are unchanged.

Source provenance and decisions

The base is the saved Scenario/Text composition rooted at 5960563b23b3f28f83343c283b7c156bf248994a, then Scenario integration 6f4dfc67b3443b2b1725e2b576eb37224977b9b2 and early stale-event correction 0b61771d079cae4a513958fad04e6c3e785d458f. These retain the root's ordinary defaults, Text/Tab, always-active canvas, rename-scroll and allocation authority.

The next two source commits compose exact delivered code/documentation deltas:

• a9b9c81: ordinary/Text 3f9e6a18..b8685416 under crates/ and docs/, including final attachment Escape and State read-only pan corrections. The Scenario invalid-route fixture additionally supplies absent attachment fields.
• ffa7b16: 3f9e6a18..55198ee5 under those paths, retaining the final persistent transition decision footer. The already-identical diagram/focus.rs formatting is retained once. The bidirectional lifecycle fixture now authors nonempty source/target attachments, bends and labels; its existing whole-Project, deletion/history/recreation/relink/round-trip oracles must conserve them.

Both net patches applied cleanly with three-way reconciliation. That is not evidence of behavioral compatibility. In particular, preserve Scenario's architecture-destination refusal, exact view/visit authority, State edit-only cancellation versus camera cancellation, and semantic ports' authority over dormant attachment preferences.

The first Scenario-only run at 0b61771 compiled and listed 129 core-library tests on 742 unchanged inputs. Its scenario_layout run passed 20 and failed seven source-lifecycle cases: the ordinary parser's closed field inventory rejected layout. Correction 2a0579daafb89994730284c108f460782e5e6650, incorporated here as 846cae8, adds layout to parser admission only. It does not add a synthetic null to CompleteForEdit or change omission defaults; real payload clearing remains distinct from unrelated edits beside explicit none. The failed receipts remain retained. At corrected 2a0579d, all 27 Scenario layout and 22 source-default library cases pass against the actual 129-name inventory on 742 unchanged inputs. These are local Scenario-only receipts; they do not establish the combined attachment/State/transition result.

Evidence scope

Existing peer evidence remains tied to its original code, not this candidate:

The independent September 23 evidence audit verified five supplied portable verifiers and supplemental actual outcome/source-binding checks. Historical failed attachment comparisons and State dirty-source gaps remain disclosed. The audit did not run their application binaries or repeat their native trials.

Retained reviews: composition plan, Scenario source and stale-event correction, combined source, and peer evidence audit. Their historical source pins and pre-execution status remain explicit; later passing gates do not retroactively turn a source review into runtime evidence.

Combined acceptance still required

First resolve any actual constructor/API/parser failures on frozen source. Verify actual test inventories and outcomes rather than adding historical totals. Core checks include Scenario source/reference lifecycle, ordinary defaults, attachments/routing/ports and both-direction transition lifecycle. Desktop checks include stale-input/navigation/spacing, all nine Text indentation cases, inspector tab return, attachment Escape and all State bend/pan regressions. HTTP checks cover conditional Scenario and attachment transactions and restart. Run full workspace tests, strict all-target lint and matching GUI build after targeted defects are corrected.

A combined native trial must exercise saved arrangement/Details/inspector Apply/Revert and Connections return, spacing/cancel, Text indentation and Apply/return, attachment versus semantic reconnect, State bend editing/cancel, transition footer/relink, and exact saved-model reopen. Peer native evidence does not replace observation of these integration seams.

Source7/schema7 versus the proposed coordinated source8 boundary is unresolved; the intermediate Scenario contribution does not settle public format adoption. Normative Scenario language/API/OpenAPI documentation is incomplete. Private analysis source8 is not merged here. Resize policy, complete accessibility, Linux and packaged-release acceptance remain separate requirements. Linux checks stay deferred under the user's instruction.
