Phase 1 of epic #1507 (ADR-1508): behavior-preserving relocation of the pure
rewrite-engine helpers out of the hand-authored installer so the conversion
module can own them without importing bin/install.js.
- getDirName -> src/runtime-name-policy.cts (pure runtime->dir-name switch).
- processAttribution -> src/runtime-artifact-conversion.cts (pure Co-Authored-By
content transform).
- bin/install.js imports both back via destructure/binding and re-exports
getDirName unchanged (Hyrum: install.test.cjs + runtime install tests import
getDirName from bin/install.js).
Two refinements to ADR-1508's Phase 1 (verified against the source):
- getCommitAttribution STAYS in bin/install.js: it is impure install-time
config I/O (reads runtime settings.json, uses install-time config-dir state +
attributionCache), not a content transform. Phase 2 will inject the resolved
attribution into the engine rather than move this function.
- The convertClaudeToAugmentMarkdown dedup is deferred to Phase 2's cleanup: the
local copy is entangled with a converter cluster (convertSlashCommandsTo
AugmentSkillMentions is used only by it; the family is partly dead-local via
the ...runtimeArtifactConversion export spread), deduping only augment would be
arbitrary, and it is not required to unblock Phase 2 (the engine will call the
conversion module's own copy when it moves).
New tests/enh-1510-*.test.cjs: getDirName at its new home (all runtimes +
fallback + install.js re-export identity) and processAttribution
(null/undefined/string/$-escape/CRLF/global). 487 affected-suite tests green.
