Round 11: PR014 visible viewport boundary
Analysis and plan
Mark the visible graph boun... (STV_PR_014) identifies the actual .stv-viewport overflow edge; the
outer widget border does not mark that internal boundary. Add a native top
border outside the transformed scene, retaining 975 px content height and all
input semantics. The plan is in the same problem report. Correct the supplied
attachment/evidence paths and provenance without inventing a missing PPTX.
Mark the viewport clipping ... (STV_SWR_062) refines Make the graph clipping bou... (STV_SHR_056), allocated to Accessible view and viewport (STV_SWE_RENDER); no artificial system requirement is needed. The concrete case Visible viewport boundary d... (STV_TC_SY_062) checks rendered clipping, resizing, host sizing and controls rather than merely matching CSS source. Existing viewport/zoom/focus, independent-view and packaging obligations remain unchanged regression context.
Findings and review gates
STV_R11_001: Intake figure/evidence paths name files not supplied under those names. Use the actual adjacent PNG and repository-relative report path; distinguish reported PPTX provenance from files supplied here.
STV_R11_002: An unqualified top border under a host border-box rule could reduce the existing usable height. Explicit content-box sizing plus actual 975 px client-area checks preserves the accepted viewport contract.
STV_R11_003: A scene-level line would move with pan/zoom, while an overlay could obscure content or intercept input. Use the native viewport border; verify its clip/pointer boundary and fixed position in the actual browser.
Current concept context includes the existing requirements/elements, diagrams, interfaces, stack and plans, canonical cases/executions and review/source records. Changes are limited to the two requirement paths, one case, viewport contract and relevant plan/demo/state-neutral prose. No library, component boundary, serialization, layout algorithm, state transition or timer changes. Accepted ADRs and unchanged diagrams retain their prior reviews; no diagram-only edits or new ADR are justified for a native CSS border. Unrelated PRSA and release gates are excluded from this scope without declaring them resolved.
Review decision
Accepted under the scoped whole-V-cycle delegation: Mark the viewport clipping ... (STV_SWR_062) and Visible viewport boundary d... (STV_TC_SY_062); stakeholder Make the graph clipping bou... (STV_SHR_056) records the exact grey-line outcome explicitly requested in PR014 and authorized for implementation. No broader stakeholder revision is inferred. The case retains its actual failed baseline attempt; acceptance of its design does not imply an implementation pass.
All three findings are closed for the concept: attachment paths are corrected, content-box sizing preserves the accepted client height, and a native container border avoids transform/overlay ownership errors. Browser reproduction confirms actual clipping with a 0 px/style-none edge over file/HTTP. The warnings-as-errors concept build and full –require-test-coverage validator passed: 56 SHR, 10 SYS, 62 SWR, 110 cases, 605 executions. The direct SHR-to-SWR channel and the case’s verifies/executed-by paths are semantically appropriate; no unrelated tooltip or system requirement was linked merely to fill the graph.
Accepted ordinary-document changes are the interface/implementation/verification marker contract and state-neutral/demo guidance. The inventory records all current concept context and scoped identities. Existing architecture/state SVG hashes match round 10’s reviewed files; their standalone/embedded visual evidence is retained there. This CSS-only change does not export or change a diagram, state action or transition, so no new diagram acceptance is claimed.
Implementation handover: add the viewport top border and explicit sizing, regenerate packaged CSS, execute the exact clipping/resizing/control procedure and adjacent usability/offline/arrow checks, verify installed asset delivery, and rebuild/validate the real project demo. Full capacity/release suites are not required for unchanged layout/data algorithms and are not claimed as rerun.
Implementation and re-review
The implementation matches the accepted native-border contract. Actual file/HTTP checks now pass clipping hit tests, neutral 1 px marker, responsive flow/width, 975 px client height under a border-box theme, keyboard controls and independent views. Negative-arrow and usability regressions passed. All 60 non-browser checks passed, including clean package consumption and source archive rebuilding; the changed packaged CSS matches the tested source asset. The complete selected development outcome is 70 passes, zero latest failures/errors/skips. The expected before-fix failures remain linked to the same canonical case.
All three scoped findings are closed. New requirement verification is justified by its complete browser criterion, not concept acceptance. No state/diagram, algorithm or dependency change occurred. Final documentation/evidence validation and inventory reconcile the scoped changes; unrelated accepted/draft artifacts retain their existing states. Full release/capacity qualification is not claimed.
Final disposition
Mark the visible graph boun... (STV_PR_014) is fixed. Final warnings-as-errors Sphinx, full evidence/ –require-test-coverage validation and strict executable mapping passed with no scoped blocker. The owner-requested outcome is delivered through the accepted requirement/design/case path and real before/after execution. The concept-gate inventory (retained in the engineering checkout) and final inventory (retained in the engineering checkout) distinguish reviewed scope from preserved context. No unrelated artifact is newly accepted, no prior execution is rewritten and no commit/tag/release is created.
