Mechanical rename produced by scripts/msd-rename.cjs: gsd/Gsd/GSD -> msd/Msd/MSD
across contents and paths, upstream package/repo coordinates -> @golem15/msd-core
and golem15com/msd-core. Deep links into upstream history, sibling upstream
packages, the GSD-2 import feature, CHANGELOG.md and .changeset/ are kept as-is.
Hand edits on top: MSD block-letter banner and logos, LICENSE copyright line,
package/plugin identity, regenerated lockfile, install-tree fixtures, derived
registries and benchmark baseline; migration checksum baseline re-locked
(MSD keeps its own install state, so no install had applied the old sums);
sort-order and regex-escaped expectations in tests adjusted.
Design-lock ADR for epic #3212 — the lexical layer beneath the #1372
markdown-sectionizer and #2143 table/mutation seams.
Locks seven decisions Phases 1-4 execute against:
- src/pattern.cts as sole owner of dynamic regex construction,
delegating to the built-in RegExp.escape; the ten private
escapeRegex/escapeRegExp/escapeRe copies are deleted, not merged
- engines.node floor raised to the Active LTS line (>=24), which is
what makes RegExp.escape reachable; delegating-shim alternative
recorded and rejected
- src/text-lines.cts as sole owner of line-terminator handling —
the primitive the existing no-crlf-fragile-split prohibition lacks;
brings frontmatter.cts in from the #1372 exclusion
- tokenizer-first for stateful grammars, with a decidable five-condition
test, generalizing the proven hooks/lib/git-cmd.js token-walk (#3129)
- bounded quantifiers over caller-supplied content
- extend-never-mutate (inherited from ADR-2143 §2)
- prohibition with teeth: no-adhoc-regex-escape, no-unbounded-quantifier,
no-crlf-fragile-split widened to src/, plus a parity assertion
Explicit non-goal: no wholesale regex-to-parser rewrite. A census found
2,113 regex literals across 317 files; most are correct and stay.
