@@ -70,10 +70,11 @@ _Last updated: 2026-09-25 03:02 UTC_
 - **CogArch Solution Factory / Argo evidence boundary (verified 2026-09-15):** exact live and archived label queries for `architecture-id=arch_kiSj9jBKI` returned no Workflow. The deployed Processing template contains conversion, chunking, image description, and merge steps, but completed Workflows are deleted after 24 hours and the accessible archive is empty. A separate `arch_xOQ5jks0b` High-Level Insights failure reached the code agent and exhausted retries with exit code 201; its overwritten detailed log reportedly showed operation timeout/retry-limit failure. A fail-open Redis DNS warning appeared in that failed run but did not recur in the read-only-verified rerun pod, so it is not the established cause.
 - **CogArch Solution Factory BYOT MVP (decided 2026-09-16):** use one persistent OpenShift Secret per user, created/patched/deleted by the existing settings backend; do not introduce IBM Secrets Manager or a new secrets service initially. Require server-derived opaque names, backend ServiceAccount permissions limited to Secret `create`/`patch`/`delete` without reads, admission restriction to labelled `byot-*` objects, trusted WorkflowTemplates, no token leakage, and fail-closed behavior. Running workflows may retain old values; provider revocation and cluster-loss recovery remain separate concerns.
 - **Emplonet v1 channel setup (confirmed 2026-09-08):** `#emplonet-v1-general` and `#emplonet-v1-ingrida` each have a dedicated local artifact workspace under `/opt/data/channels/`, a dedicated channel skill, and a private source repository in `emplonet-v1-skills-code-agent`; both are now included in the authoritative daily wiki scan and short config routing.
+- **CogArch–SAP collaboration workspace (confirmed 2026-09-25):** `#cogarch-v1-collab-sap` has a dedicated local workspace and private channel skill. Its private `reference-v1-sap` corpus covers 124 SAP Architecture Center source pages across 34 reference-architecture families and preserves 159 upstream Draw.io files with checksums and provenance; the first architecture family to assess remains open.
 - **Lego CV workspace (confirmed 2026-09-14):** `#lego-v1-cv` uses `/opt/data/workspaces/channels/lego-v1-cv` and the private `lego-v1-skills-code-agent/lego-v1-cv` channel skill. The supplied CV source was converted into brand-neutral editable DOCX and PDF artifacts without embedded IBM logos while retaining professional content.
 - **Wiki health check (repaired 2026-09-13):** `/opt/data/scripts/health-check.sh` no longer creates invalid multiline `0\n0` counts when `grep -c` finds no match, and its Discord test recognizes the gateway's actual inbound/send activity log forms. `bash -n` and a complete rerun passed all four checks; authenticated Discord REST still remains the source of truth for channel-scan coverage.
 - **Wiki usability/format questions (open 2026-09-19):** RootAtSkic wants a practical way to discover/retrieve channel wiki Markdown files instead of relying on numeric Discord-ID filenames, and asked whether migration to a Google “OKF” format would help. “OKF” and the desired delivery interface remain unclear; no migration is authorized.
-- **CogArch Shorts presentation workflow (confirmed 2026-09-24):** `Architecture in an AI World` is maintained in the dedicated Shorts workspace. Full-deck previews must stack every slide vertically with a visible slide number; the revised deck consolidates former slides 3–5 and 6–7 and includes linked reference slides for FINOS CALM, Structurizr, and ArchiMate.
+- **CogArch Shorts presentation workflow (confirmed 2026-09-26):** `Architecture in an AI World` is maintained in the dedicated Shorts workspace. Always return the latest deck as one image attachment per slide, in order; do not use a combined preview. The revised deck consolidates former slides 3–5 and 6–7, includes linked FINOS CALM, Structurizr, and ArchiMate reference slides, preserves design as a hard problem in the opening thesis, and removes the referenced “prompt enablement backbone” and “minutes” content (exact slide location was not stated in the source message).
 - **Jev evaluation (open 2026-09-19):** investigate Jev’s practical Home v1 uses, TrueNAS app availability/deployability, and likely impact; the request did not authorize deployment.
 - **Operator communication preference (confirmed 2026-09-19):** use retained knowledge of RootAtSkic’s character/principles and provide concise, decision-oriented summaries rather than large reading dumps.
 - **Hermes delegation baseline (live 2026-09-12):** `max_concurrent_children: 10` and `max_spawn_depth: 1`; RootAtSkic asked how to increase sub-agent capacity, but no configuration change was authorized or made.

 - ✅ On 2026-09-13 the recurring health-check defect was repaired: zero-match `grep -c` output can no longer become the invalid multiline value `0\n0`, and the Discord check now recognizes the gateway's actual inbound/send activity log forms. A syntax check and complete rerun passed all four checks; the same run's authenticated Discord REST scan succeeded for 31/32 monitored channels.

Eight human messages in `#cogarch-v1-shorts` were newer than the previous daily-run anchor; seven were already captured by the channel workflow, while message `1552962884965761069` added a durable deck-content removal directive and advanced the wiki anchor. The run also incorporated the newly monitored `#cogarch-v1-collab-sap` route.

 - Deck decision: former slides 3–5 were consolidated into one slide based on slide 4. The combined slide places six participant questions around one shared architecture model and incorporates the architecture content of purpose, structure, qualities, decisions, ownership, and traceability.
 - Deck decision: former slides 6–7 were consolidated into one slide based on slide 6. The combined slide preserves the Architect Curates / AI Accelerates split and adds a compact Encode → Act → Validate → Learn feedback loop.
 - Deck decision: three visual reference slides were added after the shared-model slide: FINOS CALM, Structurizr, and ArchiMate. Each carries a verified, clickable link to its official documentation; the deck duration changed to 15–20 minutes.
-- Presentation preview decision: when showing a full deck, stack slide images vertically in sequence, one slide per row, and add a clearly visible slide-number header above every slide; do not use a thumbnail contact sheet.
+- Opening-slide decision: address a top-tier architect audience with a substantive, debatable thesis rather than a basic orientation statement. Preserve design as a continuing hard problem; present AI as multiplying architectural decisions and the coherence burden, not replacing the design challenge. Do not mention cheaper code. Current thesis: “AI does not reduce the challenge of design. It multiplies the decisions architecture must keep coherent.”
+- Presentation preview decision (supersedes the earlier composite-preview rule): always return every slide as its own image attachment, in slide order. Do not combine slides into a single vertical image or thumbnail contact sheet, because combined previews are difficult to view. When the user changes or reinforces this preview approach, immediately return the latest presentation version as separate slide images; do not only acknowledge or record the preference.
+- Deck-content decision: remove “prompt enablement backbone” and “minutes” from the referenced deck location. The source message does not identify a slide number, so the exact target location remains **UNKNOWN** in this ledger rather than inferred.

+## Purpose
+
+Coordinate CogArch v1 collaboration with SAP while keeping scope, evidence, decisions, ownership, and resulting artifacts explicit.
+
+## Canonical Resources
+
+- Workspace: `/opt/data/channels/cogarch-v1-collab-sap/`
+- Channel skill: `cogarch-v1-channel-collab-sap`
+- Skill repository: https://gitea.lego-cloud.eu/cognitive-architect-v1-skills-code-agent/cogarch-v1-channel-collab-sap
+- SAP reference corpus: https://gitea.lego-cloud.eu/cognitive-architect-v1-architectures/reference-v1-sap
+- Local SAP reference checkout: `/opt/data/channels/cogarch-v1-collab-sap/repositories/reference-v1-sap/`
+
+## Key Decisions
+
+- This channel has a dedicated local workspace and a dedicated remotely maintained skill.
+- The skill repository uses private visibility and `main`; initial verified skill commit: `81f734a9de408195f322871bd9311dd0c6cba104`.
+- Channel ID `1553018070845624452` is routed to `cogarch-v1-channel-collab-sap` through the channel-wiki source mapping and generated Hermes configuration.
+- SAP reference architectures are maintained in private organization `cognitive-architect-v1-architectures`; the initial `reference-v1-sap` corpus is verified at commit `36261177a49b6178eb5314be08ec778f33a21b38`.
+- The initial corpus analyzes 124 source pages across 34 RA families and preserves 159 upstream Draw.io files with checksums and immutable provenance.
+- Mutable channel context belongs in this wiki, not in Hermes gateway configuration or the reusable skill.
+- The channel name does not itself establish SAP endorsement, partnership, access, licensing, or authority to make external commitments.
+
+## Active Topics
+
+- Use the SAP reference corpus to identify relevant patterns for concrete CogArch collaboration use cases.
+
+## People & Roles
+
+- RootAtSkic (`1518725627845283888`) — channel owner and human authority.
+- Hermes (`1526860732917088266`) — assisting bot.
+
+## Action Items
+
+- Select the first SAP architecture family to assess or transform into a CogArch-specific view.
+
+## Evidence
+
+- `1553018194006904993` — RootAtSkic requested local-folder setup and a channel-attached skill maintained on the remote.
+- `1553030154962473040`, `1553100868654735491` — RootAtSkic requested the SAP Architecture Center corpus, editable diagrams, and the final organization name.
