# Direct scenario editing — bounded implementation plan
|
|
|
|
Status: implementation in the isolated `codex/scenario-direct` checkout, based on
|
|
ab661f2. Native acceptance is pending the root's Windows/Linux trials. This does
|
|
not complete the release or the separate process/chain gesture work.
|
|
|
|
## Decisions
|
|
|
|
Extend the existing `behavior::Scene`; retain its derived lifeline columns and
|
|
ordered occurrence rows. No model/schema/layout records are added. Lifeline and
|
|
occurrence UUIDs remain distinct from represented work and global exchanges.
|
|
|
|
Select mode selects headers, stems, messages and occurrence boxes. A selected
|
|
occurrence has a reorder handle; dragging it chooses a visible slot in its same
|
|
parent sequence. It never reparents or changes lifeline columns. A Message tool
|
|
uses the existing MessageStyle, with Call + correlated reply initially selected.
|
|
Click-click or drag between represented lifelines captures a highlighted explicit
|
|
insertion slot `(parent, before occurrence or append)` and opens the existing
|
|
typed draft with those endpoints. Existing exchanges/calls are filtered against
|
|
the complete candidate at that slot and shown through search plus 24-item pages.
|
|
No compatible exchange produces an actionable retained draft, not a new global
|
|
exchange or a silently changed endpoint. Timer remains available as a local tool.
|
|
|
|
The canvas remains rendered while a bounded, independently scrollable form is
|
|
open. Values keep the existing qualified-path editor and lifecycle. Final creation
|
|
uses ordinary CreateElement plus SetSteps in one Batch; paired call/reply are
|
|
inserted together and undo together. Reordering uses SetSteps within the captured
|
|
parent. Existing core validation decides reply order, branch dominance, lifetime,
|
|
phase and endpoint compatibility. Failed preparation/source writes retain drafts.
|
|
|
|
Transient events capture document/scenario/revision/epoch, and the App validates
|
|
the current Behavior owner before handling them. Selection does not invalidate a
|
|
gesture within the same scenario. Escape, unfocus, context/tool change and pending
|
|
drafts cancel gestures. Ordered pointer events and captured window positions avoid
|
|
coalesced-click and changed-scroll-origin commits. No geometry is persisted.
|
|
|
|
Execution bars derive their ends from actual correlated reply positions; separate
|
|
conditional reply branches render their corresponding spans. Calls without a
|
|
visible reply use a short explicitly open activation, not a fabricated reply.
|
|
|
|
## Acceptance checks
|
|
|
|
Production-event tests cover hit priority, click-click/drag, scroll-origin changes,
|
|
Escape/unfocus/stale contexts and exactly one result per gesture. Planner/App tests
|
|
cover middle/operand insertion, paired identities, complete SetSteps ordering,
|
|
same-parent reorder, rejected reply-before-call, unchanged global exchanges, exact
|
|
source/model Undo, draft retention and bounded exchange/call controls. Run focused
|
|
and full desktop tests, strict all-target desktop Clippy and optimized build with
|
|
the dedicated `D:/CodexBuilds/Capella2-scenario-target` target.
|
|
|
|
Root native tasks (not yet performed):
|
|
1. Draw an existing exchange again into the middle of a scenario as Call+Reply;
|
|
enter a qualified value, select both occurrences, Undo/Redo, save/reopen.
|
|
2. Insert inside an ALT/LOOP operand, reorder within it, reject a reply before its
|
|
call, and inspect correlated execution bars and preserved occurrence identities.
|
|
3. Cancel drawing after scrolling/layout change, retry, retain typed values while
|
|
navigation is blocked, and open/return from a referenced scenario. Verify at
|
|
1440x900 and 1100x700 on Windows and Linux before scoped acceptance.
