The vita page carried a hand-typed duplicate of education, publications,
presentations, and experience, and had drifted from the PDFs in about
fifteen places — Shu Lab still one entry titled "Undergraduate
Researcher" three months after the degree, Weenix at ~7,000 lines, CHASE
still "accepted" after being presented, a preprint missing entirely, and
two different code URLs for the same paper.
build/Vita.hs reads yaml-source/data/*.yml — the same files the PDF
pipeline builds from — and renders education, experience (keeping the
CV's research/industry split), publications, presentations, and contact.
Drift is now structurally impossible rather than merely discouraged.
Notes on the implementation:
- The YAML is LaTeX-flavoured because xelatex is its first consumer, so
values pass through a small closed converter (\textbf, \textit,
\texttt, \href, $\times$, $\delta$, \#, {,}, ~, --, ---). Escaping
happens before conversion; unhandled commands pass through visibly
rather than silently dropping their argument.
- Scalars are parsed loosely: the same logical field is sometimes a YAML
number and sometimes a string (`year: 2026` vs `year: "2026--2027"`),
and the PDF pipeline does not care, so this does not force it to.
- personal.yml's phone number is deliberately not read. It is printed on
the CV, which is handed to a chosen reader; this page is crawled.
- Contact chips carry labels (ORCID, Forgejo, GitHub) rather than the
CV's full display values, which exist because paper cannot be clicked.
The page keeps only what nothing else on the site owns: the pointers and
the four research threads. In-progress work belongs to /current, the
engineering index to /cv/projects/, and the narrative to /me/ — whose
abstract already described this page as the formal record.
vita.css composes on item-card.css and mirrors now.css's headings and
chip geometry, so /about and /current read as one system. Link chips get
the only interaction polish on the page, being the one affordance a
printed CV cannot offer.

New inline logo-mark.svg partial in the nav (two-tone cutout via
--logo-ink/--logo-bg), regenerated favicon set + web-app manifest icons
from the new mark, 1200x630 og-image wired into head.html.
Known follow-ups (AUDIT-2026-06-09.md §9): the traced SVG is ~33 KB
inlined per page, favicon.ico carries 128/256px entries, and the
webmanifest dropped its maskable purpose.

Preserve external works the site cites against link rot, host them at
permanent /archive/<slug>/ URLs in site chrome, and treat them as
first-class citizens of the backlinks and similar-pages indexes.
Curated, not crawled: the author adds one line to archive/manifest.yaml
and the build fetches, hashes, snapshots, and indexes the work.
* archive/manifest.yaml + tools/archive.py (fetch / refresh / wayback /
check / gc) — PDFs downloaded directly, HTML pages snapshotted with a
vendored monolith (tools/bin/monolith @ 2.10.1) into a single
self-contained file with the archive CSP and a noarchive robots meta
injected. Per-entry PROVENANCE.json committed; gitignored .txt
sidecars regenerated from the artifact's SHA-256.
* build/Archive.hs + build/ArchiveIndex.hs + build/Filters/Archive.hs
— Hakyll rules for /archive/ and /archive/<slug>/, a body Pandoc
filter that appends an archive affordance to live citations and
flips dead ones to the local copy on archive.py check's asymmetric
hysteresis (rotted needs 3 fails over >= 14 days; one ok recovers).
* build/Backlinks.hs — keeps archived external URLs through pass 1 and
canonicalises them to /archive/<slug>/ in pass 2, producing a
"Referenced by" section grouped by the fragment each citation
targets. build/Stats.hs gains a "Link archive" telemetry block on
/build/ (count, total size, median age, by-status / by-quality /
by-visibility, orphans).
* Integrity: archive.py fetch and build/Archive.hs (via sha256sum)
both re-hash every committed artifact, so a tampered file halts the
build even with cabal invoked directly or no .venv present. refresh
refuses to replace an uncommitted prior snapshot and rolls back
atomically on any exit path. removed.yaml is honoured by fetch,
wayback, and check using canonical-form (tracking-stripped,
arXiv-canonicalised) comparison.
* visibility: private keeps an entry in-repo but undeployed.
nginx/archive.conf emits X-Robots-Tag: noindex, noarchive for raw
artifacts that cannot carry meta directives.
The full design, phase plan (1-5), and three refinement passes live
in ARCHIVE.md.
