Project Diary - Day 23 - March 29, 2026

Day 23 opened on Saturday March 29th. The session had a clean restart — full tar package dropped at session open including cli-tools-start-here.html, deep-dive-index.html, ollama.html, fzf.html, AI_learning_plan_ai-x.html, and AI-NEW.html as style and content references.

Primary goal was the tmux deep-dive page, which had been identified as the strongest next content candidate at the end of Day 22. The page was built in full and validated clean with vnu. Three supporting files were patched to integrate tmux into the existing toolchain documentation. The chronic ai_websites anchor deferral from Day 16 was resolved with a one-line fix to AI-NEW.html.

Session included an interruption mid-deploy which required a pause and clean resume. All files deployed and validated before session close.

New Pages This Session

deep-dive/tmux.html — NEW

Full CLI tool deep-dive page for tmux. Sections: What Is tmux, Installation, Basic Usage (session/window/pane model, essential keybindings table), SysAdmin Use Cases (long-running jobs, multi-pane monitoring, patch night workflow, shared sessions, persistent log watching), tmux + AI Tools (sgpt pane workflow, aider session persistence, ollama serve in tmux, fabric pipeline monitoring), Configuration (~/.tmux.conf baseline), Honest Assessment, Related Tools. 739 lines. vnu clean.

Files Patched This Session

deep-dive/deep-dive-index.html — PATCHED

tmux card added to the 🐧 AI for Unix/Linux section, after the gh card.

deep-dive/cli-tools-start-here.html — PATCHED

Three additions to integrate tmux into the toolchain documentation:

Toolchain diagram — SESSION LAYER block added after github-copilot
Quick Reference table — tmux row added (Low complexity, No API key)
All Tool Pages section — tmux hub-link card added; section title updated from “All Eight Tool Pages” to “All Tool Pages”

AI-NEW.html — PATCHED

Anchor fix: id="quick-access" added to the Quick Access — External Resources <h2>. Resolves the chronic ai_websites anchor deferral that had been on the 2DO list since Day 16.

Note: AI_learning_plan_ai-x.html was reviewed — the only local href referencing ai_websites was already commented out. No live broken links in that file.

collaboration/project-diary.html — PATCHED

Day 23 card added with links to this diary file, the Day 24 2DO, and the addendum notes file.

Observations

tmux is a satisfying page to write because the content is genuinely useful and the AI integration angle is natural — tmux is the infrastructure wrapper that makes every AI tool at the terminal more reliable. The “SESSION LAYER” framing in the toolchain diagram feels right: it is not an AI tool itself but it belongs in the toolchain documentation.

The anchor fix that had been deferred since Day 16 turned out to be a single line. Classic case of a small task that kept getting bumped. Done now.

The interrupted session resumed cleanly. The one-file-at-a-time deploy protocol with vnu confirmation at each step held up well under the stop/start conditions.
