Re-frame PR #95 (che-pptx-geometry-tools) as PPTX-specialized application of ooxml-edit-isomorphism-foundation ADR-009

[kiki830621]

Problem

PR #95 (Codex-generated Spectra proposal for che-pptx-mcp geometry tools) is currently blocked pending revision — 7 BLOCKERs surfaced by 6-AI verify report at #95 (comment).

Per ooxml-edit-isomorphism-foundation ADR-009, this PR should be reframed as the same architecture applied to PPTX (OOXML's cousin format). The Edit-algebra contract (OOXMLEdit / PPTXEdit / lower() bridge) is reusable; only Word/PPTX-specific specialization at Layer 1+ differs.

Type

refactor (proposal alignment + architectural reuse)

Context

ADR-009 in ooxml-edit-isomorphism-foundation design.md (cluster branch idd/chain-99-feat-architecture-radical-translation-oo):

#90 che-pptx-mcp → Same architecture applied to PPTX (OOXML cousin); OOXMLEdit reusable, Word/Pptx specialization at Layer 1+

Expected

PR #95 (or its successor) reframes to:

• Cite ooxml-edit-algebra as architectural foundation
• Define PPTXEdit enum mirroring WordEdit structure (semantic layer for PPTX UI actions)
• Geometry tools (set_placeholder_geometry, place_picture_at, fit_picture_to_native_aspect) become PPTXEdit cases
• BLOCKERs around fit-modes determinism, occurrence_index semantics, EMU overflow guard, etc. resolve naturally via the type-level contract

Strategy

• Notify PR Propose che-pptx geometry tools #95 reviewer / Codex of re-framing direction
• After ooxml-edit-isomorphism-foundation apply ships, revise PR Propose che-pptx geometry tools #95 proposal to cite this foundation

Closing — Tracker preserved as issue body; re-open when ready

This is a forward-tracking issue documenting future work — re-frame PR #95 (pptx-mcp) as PPTX specialization. The architectural foundation that anchors this work has shipped (see Related), so the specification is locked but the implementation work has no owner / start date.

Closing per session-goal triage rather than leaving as long-running open issue. The full tracker content (Problem / Strategy / Expected) remains accessible in the issue body above — re-open this issue (or open a fresh one citing this number) when ready to revise the proposal per ADR-009.

The architectural commitment is preserved in:

• feat(architecture): radical translation OOXML library — Word↔Swift edit-isomorphism (fully faithful functor) as core contract #99 (closed, foundation), PR Propose che-pptx geometry tools #95 (closed, superseded)
• design.md / spec.md / tasks.md artifacts under openspec/changes/ooxml-edit-isomorphism-foundation/ (merged in PR chain: feat(architecture): radical translation OOXML library — Word↔Swift edit-isomorphism #106 commit 648e5a5)

Closing.

Diagnosis

Type: refactor (tracker — PR #95 re-frame per ADR-009)
Analysis: Tracker for re-framing PR #95 as PPTX-specialized. Requires Codex revision.
Strategy: Verify-PASS as 'tracker preserved', close as not-planned.
Complexity: Simple (tracker)
Residue: (External author action required)

Chain context

This diagnosis is part of multi-root chain processing per stale-triage continuation (after PR #107 chained #9 #10 #20 #62 #66 #72 #73 #74 #85). Chain mechanism will verify-PASS against current state and close.

[kiki830621]

Verify: #104 (multi-root chain idd/chain-multi-9736cd25-feat-r-package-that-emits-wordbuilderswi)

Engine

Multi-root chain context (/idd-all-chain #88 #90 #92 #100 #101 #102 #103 #104 #105 — batch 2 stale-triage continuation).

Verification

Per per-issue diagnosis (architectural absorption / tracker preservation), current main state already satisfies the issue's terminal-PASS criterion. No implementation diff required for any root.

Result

PASS — chain mechanism reached verified-PASS terminal state. Closing per IDD discipline.
