docs(community): 2026-09-09 meeting pages

[LiamRandall]

Landing and transcript pages for the September 9, 2026 wasmCloud Wednesday (video), replacing the agenda stub at community/2026-09-09-community-meeting.mdx.

Topics: Eric Gregory walks the wasmCloud 2.9 release — NATS-native workloads, guest memory from advisory to enforced, and Kubernetes-grade lifecycle (real /livez and /readyz, draining shutdown, startup patience, bus-loss safeguard, descriptor exhaustion). Bailey Hayes argues wasmCloud is the only open source multi-tenant WebAssembly platform, explains why a v3 waits on Component Model 1.0 and runtime instantiation, and gives the clearest account yet of cooperative threading (WASI 0.3.3 in December, ABI in LLVM 23, Open POSIX pthread suite passing). Victor Adossi demos newly landed Node.js API support in JCO 1.33.0.

Structured data — the 2026-09-02 warning is resolved here

The single no about or mentions (M12 entity refs) warning on #1266 came from this agenda stub: community/2026-09-09-community-meeting.mdx carried only date and title, no about/mentions and no slug, so it was served at the date-based /community/2026/09/09/community-meeting/. Both 2026-09-02 pages already carried about + mentions + slug and were never implicated.

Replacing the stub clears it. A full validator sweep on this branch:

[validate-structured-data] checked 889 HTML file(s), 5061 JSON-LD payload(s)
[validate-structured-data] OK

0 errors, 0 warnings (was 1).

Standards

• Speakers — 6 slugs resolve against src/data/people.json; VideoObject.actor[] emits all 6 with affiliations. Wires the meeting onto the five maintainers' /people/<slug>/ pages.
• New person — adds shreya-deshannavar (community role) on her first appearance as a speaker. Her surname was read from her Zoom name tag; she self-identified by first name only.
• One speaker deliberately not named — Speaker 5 was camera-off with no tile on any gallery page across five sampled turns, and the only candidate address is Otter's garbled "a question for Frick" at 22:53. That does not meet rule 15's bar of two direct addresses by name from different people, so the turns are kept as Community Participant rather than guessed, and no actor edge is emitted. If someone recognizes the voice, it's a one-line fix in both files plus the speakers: array.
• JSON-LD — duration: 2820 yields 23 Clip entries, every one with an endOffset. about: wasmCloud plus 11 mentions: on both pages, all slugs present in entities.json.
• Links — verified v2 routes only, including the anchors the 2.9 release post uses (#wasmcloudnats, #runtimeresourcesguestmemorymode, #component-resource-controls). npm run build passes with onBrokenLinks/onBrokenAnchors: 'throw'.

SEO

Primary keyword webassembly kubernetes (🟢, protected ranking at pos 10 → target top 5) — this call is unusually on-topic for it: probes, draining, terminationGracePeriodSeconds, bus-loss, descriptor exhaustion, and guest memory limits that bind before the pod's OOM killer does. Carried through the title, description, TL;DR, and a Topic Deep Dive on what "WebAssembly on Kubernetes" has to mean operationally. Also reinforces the protected wasm component model position (pos 16) via the Component Model 1.0 roadmap segment, plus jco, nodejs webassembly, cooperative threading, and guest memory enforcement.

Frames

11 WebP frames from the local recording into static/img/community/2026-09-09/, raw <img> tags in the transcript. No 0-byte frames; recording length (2820.55s) matches the Otter export.

Verification

• npm run build passes
• validate-structured-data.mjs: 0 errors, 0 warnings
• Every [MM:SS](…?t=N) satisfies N == seconds(MM:SS) on both pages
• chapters: frontmatter matches the ## Chapters list exactly, sorted, duration > max(chapters)
• All 11 <img> paths resolve to non-empty files
• Transcript starts at the welcome line; pre-show banter trimmed
• Commit is signed (SSH, liam@cosmonic.com)
