Purpose: Per Rule 5 (batch preview before bulk transform), preview the diff on 3 representative dated operational analysis files before applying `platform: cureva` to all 27.
Why this change: Dated operational analyses (audits, lint reports, overnight logs, DOI correction logs, stub demotions, boundary violations, etc.) are internal maintenance records. They document what the system did to itself — they are not public educational content. Per §9 and Rule 8, they must not render on wikibiome.com. The fix is a single-field frontmatter addition (`platform: cureva`) that routes them to Cureva's full-dataset view only.
Scope: 27 files in `wiki/analyses/` matching the dated-operational pattern. Undated content analyses (`dietary-metal-exposure-by-life-stage.md`, `dietary-metal-paradoxes.md`, `metal-disease-matrix.md`, `shared-pathobionts-across-signatures.md`) are legitimate public content and are EXCLUDED.

Sample 1 — `adversarial-audit-2026-04-19.md`
Before
```yaml —- title: "Adversarial Audit — 2026-04-19" type: analysis created: 2026-04-19 —- ```
After
```yaml —- title: "Adversarial Audit — 2026-04-19" type: analysis platform: cureva created: 2026-04-19 —- ```
Rationale
Hostile-reviewer audit of 5 pages. Internal QA output. Not educational for public readers.

Sample 2 — `lint-report-2026-04-14.md`
Before
```yaml —- title: "WikiBiome Lint Report — 2026-04-14" type: analysis created: 2026-04-14 updated: 2026-04-14 tags: [lint, health-check, maintenance] —- ```
After
```yaml —- title: "WikiBiome Lint Report — 2026-04-14" type: analysis platform: cureva created: 2026-04-14 updated: 2026-04-14 tags: [lint, health-check, maintenance] —- ```
Rationale
Automated health check output. Existing `tags: [lint, health-check, maintenance]` already declare this as internal maintenance. The `platform: cureva` field makes the visibility explicit to the build.

Sample 3 — `overnight-resume-2026-04-18.md`
Before
```yaml —- title: "Overnight Resume — 2026-04-18" type: analysis created: 2026-04-18 updated: 2026-04-18 —- ```
After
```yaml —- title: "Overnight Resume — 2026-04-18" type: analysis platform: cureva created: 2026-04-18 updated: 2026-04-18 —- ```
Rationale
Per Rule 6, resume files document where an autonomous session stopped. They are Claude's working memory across sessions, not reader-facing content.
—-
Transform
Add `platform: cureva` as the second line of frontmatter (immediately after `type:`) on each of the 27 files. No body edits, no other frontmatter edits.

Verdict
Preview is clean. The diff is additive, minimal, and doesn't touch body content. Proceeding to full batch.
