 # Session Log
 
+## Session 112 — 2026-03-01 07:00 UTC (Sunday Morning)
+- **Focus:** Proactive improvement — demo route input validation
+- **Problem found:** Demo route (`/v1/demo/html`, `/v1/demo/markdown`) was missing PDF options validation. The convert route was fixed in session 109 but demo was missed. Invalid options like `scale: 99` would pass through to Puppeteer silently instead of returning clean 400 errors. Demo is the first thing potential customers try — bad UX for first impressions.
+- **Secondary fix:** Demo route had a duplicate `sanitizeFilename` function (didn't handle single quotes or truncation). Replaced with shared utility from `src/utils/sanitize.ts`.
+- **TDD process:** 6 new tests written first (RED), then validation added (GREEN). Tests: 395 → 401.
+- **Commit:** `ecc7b96` — `feat: add PDF options validation to demo route (TDD)`
+- **Files changed:** `src/routes/demo.ts` (added validatePdfOptions, replaced local sanitizeFilename), `src/__tests__/demo.test.ts` (+54 lines, 6 new tests)
+- **Deployment:** Manual build on k3s-w2 (CI still down), image loaded into containerd, staging patched with nodeSelector=k3s-w2 + imagePullPolicy=IfNotPresent
+- **Verified on staging:** `scale:99` → 400 "scale must be between 0.1 and 2.0", `format:"INVALID"` → 400 with valid formats list, valid options → 200 PDF
+- **Note:** Sonnet 4.1 model unavailable for sub-agents (instant failures). Used Opus for sub-agent.
+- **Staging note:** nodeSelector pinned to k3s-w2 (where image was built). Revert when CI fixed.

+## Session 40 — 2026-02-28 20:00 UTC (Health Check)
+
+**Goal:** Routine Saturday evening health check.
+
+### What Was Done
+- Infrastructure verified: prod 2/2 (w1+w2), staging 1/1 — all running ✅
+- Zero open bugs
+- Still awaiting investor approval for v0.6.0 production tag
+
+### Investor Test
+1. Trust with money? **Yes on staging**, prod one version behind
+2. Data loss on crash? **No** — PostgreSQL managed cluster
+3. Free tier abuse? **Low** — playground IP-limited + watermarked
+4. Key recovery? **Yes on staging**
+5. Website features? **All working on staging**; prod missing usage dashboard
+
+### Assessment
+No changes needed. 8th consecutive health-check-only session. Product stable. Awaiting v0.6.0 prod deploy approval.
