8 pages rendered as `| MGT | MGT` in browser titles

Root cause: The root layout defines a title template (`%s | MGT`). Two of my own edits plus six older pages left `| MGT` baked into the `metadata.title` value. The template appended a second suffix, producing double brand suffixes in the tab and in Google snippets.
Detection: Chrome DevTools MCP Phase 14-16 post-deploy test suite fetched each page and regexed the rendered `<title>`. The double-suffix pattern jumped out on the first check.
Resolution: Stripped ` | MGT` from `metadata.title` on all 8 pages. Left `openGraph.title` and `twitter.title` unchanged since those bypass the template.

Apr 17, 2026|Low|/blog

Root cause: A blog post (`120-social-media-actions-one-day`) referenced `/images/blog/120-social-media-actions.webp` but the file was never uploaded. Lighthouse flagged errors-in-console, knocking Best Practices from 100 to 96.
Detection: Live-site Lighthouse audit post-deploy. The only failing audit pointed straight at the console error.
Resolution: Short-term: swapped the `coverImage` to `parallel-agents.webp` (thematic match). Follow-up: generated the proper asset with Nano Banana Pro and pointed the reference back.

Apr 17, 2026|Low|/services

Root cause: The services grid had two variant hover shadows: gold for the primary card and a cyan `rgba(0,200,255)` for the secondary cards. DESIGN.md specifies architectural monochrome with amber-only accents. The cyan was drift from an older color palette.
Detection: Phase 3 design consistency sweep in the auto-audit loop. Grep for non-system colors flagged the file.
Resolution: Replaced cyan glow with neutral white at low opacity. Matches the pattern Cycle 23 applied to about.tsx.

Apr 17, 2026|High|repository (not production)

Root cause: Site-wide style rule bans em dashes. New authoring (human and AI) defaults to em dashes in prose and metadata. Without a lint rule, drift accumulates between audit passes.
Detection: Cycle 4, 6, 7, 22, 23, 25, 26 all found new em dashes. The pattern is visible across the improvement log.
Resolution: Each cycle removes them in bulk. Proposal tracked: a pre-commit hook that flags em dashes in JSX text nodes and metadata strings. Would reduce the seven cycles of patchwork to a zero-drift baseline.

Apr 16, 2026|Medium|infra (local dev)

Root cause: Running `vercel env pull` dumps every production environment variable to a plaintext file next to the repo. Stripe `sk_live`, database passwords, GitHub PAT, Brevo key all sat in a file one careless `git add` away from a commit.
Detection: Cycle 2 Phase 2 security sweep during an auto-audit pass.
Resolution: Flagged as CRITICAL in the improvement log. Still not mitigated (seven cycles stale). Proposal: delete the file after CI pulls it, or switch to `vercel env pull --environment=preview` for local work. Awaiting product direction.

Apr 16, 2026|Low|moderngrindtech.com performance

Root cause: A PNG export at 2048x2048 never got compressed. next/image serves modern formats but cannot shrink the source below what the source gives it. The about page LCP took the hit.
Detection: Performance backlog item flagged across cycles 2, 22, 23, 24, 25.
Resolution: Cycle 25 piped the asset through sharp: resized 2048 to 1200, encoded as WebP at quality 85. Final size 52 KB, a 99.2 percent reduction with no visible quality loss at the rendered 400x400 size.

Apr 15, 2026|Medium|moderngrindtech.com SEO

Root cause: Before the title template was standardized, individual pages hard-coded ` | MGT` at the end of their titles. When the template was introduced, every hard-coded suffix became a double suffix. Same class of bug as the Apr 17 incident above, just a bigger batch.
Detection: Manual audit of rendered titles across the site.
Resolution: Single pass removing ` | MGT` from 42 `metadata.title` values.

Every fix is public. Every regression has a commit. The next project you work on should be this transparent too.
