Update all docs titles to human-readable (#117) ## Summary - Updated frontmatter `title:` in all 63 doc cards from slug-case to human-readable (e.g. `borgmatic` → `Borgmatic`, `ai-assistance-guide` → `AI Assistance Guide`) - Titles now closely match file stems so `[[wiki-links]]` render naturally without alternate anchor text - Corrected titles that diverged from stems (e.g. `host-inventory` → `Hosts`, `grafana-alloy` → `Alloy`, `argocd-applications` → `Apps`) - Deleted `title-test-alpha.md` and `title-test-beta.md` test cards and removed their reference index entry ## Deployment and Testing - [x] `docs-check-links` passes — all wiki-links valid - [x] `docs-check-index` passes - [x] `docs-check-filenames` passes - [ ] Verify titles render correctly on docs site after deploy Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/117

title: Prometheus
Adopt Dagger CI for docs build (Phase 2) (#157) ## Summary Migrates the docs build pipeline to Dagger (Phase 2 of the Dagger CI adoption plan). - **Backfill `date-modified` frontmatter** on all 80 docs — Dagger's `--src=.` excludes `.git`, so Quartz can't use git history for page dates. Frontmatter dates work with or without git. - **New `docs-check-frontmatter` mise task + pre-commit hook** — validates all docs have `title`, `tags`, and `date-modified` - **New Dagger functions** — `build_changelog` (towncrier in Python container) and `build_docs` (chains changelog → Quartz build in Node container, returns tarball) - **Simplified CI workflow** — the ~44-line inline Quartz build (clone, npm ci, build, tar, cleanup) is replaced by `dagger call build-docs`. Changelog step remains local on the runner since towncrier needs to modify the host working tree for the git commit. ### Design decisions - **Towncrier runs twice in CI**: once inside Dagger (for the docs tarball) and once on the runner (for the git commit). This is intentional — Dagger's directory export is additive and can't delete the consumed changelog fragments from the host. - **Artifact hosting stays on Forgejo Releases** (not migrated to Forgejo Packages as the plan doc originally suggested). That migration can happen independently. - **`date-modified` frontmatter** preserved even though `build_changelog` installs git — the git there is only for towncrier's `git add` call, not for history. The local iteration story (`dagger call build-docs --src=. --version=dev` with uncommitted changes) depends on frontmatter dates. ### Local iteration ```bash dagger call build-docs --src=. --version=dev export --path=./docs-dev.tar.gz tar tf docs-dev.tar.gz | head -20 ``` ## Deployment and Testing - [x] `dagger call build-docs --src=. --version=dev` produces valid 1.1MB tarball (149 HTML pages) - [x] Pre-commit hooks pass (including new `docs-check-frontmatter`) - [ ] Full `workflow_dispatch` run after merge 🤖 Generated with [Claude Code](https://claude.com/claude-code) Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/157

Enforce unique doc filenames and simple wiki-links (#109) ## Summary - Rename section index files to match their titles (tutorials.md, reference.md, how-to.md, explanation.md) so all filenames are unique - Convert all ~47 path-based wiki-links to simple filename format across 15 files - Update doc-filenames task to no longer skip index.md files - Update doc-links task to reject path-based links containing '/' This ensures all wiki-links work correctly in obsidian.nvim by making links resolvable by filename alone. ## Testing - `mise run doc-filenames` - all unique - `mise run doc-links` - no broken or path-based links - `mise run doc-titles` - no duplicates Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/109
