Adopt the rules-swift pin-and-codify strategy in snapshot mode (third_party/rules-swift
@97dc70f + sha256), add codified gates, a conformance audit ledger, and
.github/workflows/rules-swift.yml (corpus-pin integrity required, full gate report mode).
Remove the docs/rules mirror it supersedes (repo-specific files kept under docs/). Style
and leak gates exclude the vendored corpus.
The bar for shipping PureXML in an IDE: correctness total and characterized,
false positives at zero, not "passes the suite." Four stoppers (reject no valid
input; accept no faulty input; characterize correctness via differential + fuzz,
no silent under-rejection debt; interactive safety: bounded resources, located
recoverable errors) plus a per-iteration checklist and definition of done.
Wired into the per-iteration protocol (schema-validity-burndown.md) and the
session Read First list (CLAUDE.md) so it is read every iteration.
Root Swift package mirroring PureYAML's structure, rules, and verification
gates. Includes the XML node model (Node, Element, Attribute, QualifiedName),
a working emitter (Serializer) with escaping and pretty/compact options, and
structural validation. The parser surface is stable; parse() raises
notImplemented until the scanner lands, pinned by a test.
- dependency-free, namespaced under PureXML
- portability and style gates carried over (style, namespacing, forbidden
patterns, swiftformat, swiftlint, linux, wasm, windows CI)
- 11 tests passing
