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.
Documents the new architectural surface #1820 introduces, per the
contributor-standards ADR requirement (a new Module seam that other code
will depend on):
- The spec-section detection Module seam (src/spec-section.cts) and its
locked exported surface, supply rule, suffix-tolerant header invariant,
and ownership boundary (detection only).
- The workflow.specless_probe_fallback toggle as a policy decision
(default-on, disableable cost-gate over the fallback INVOCATION path, not
the verifier<->predicate contract) — records the maintainer 857:66 ruling
rather than amending it.
- The SPEC-supplied <-> probe-derived precedence & authoring contract:
section-level precedence (a SPEC-supplied section is never re-run), one
projectProhibitions serializer (no second producer), descriptor-less
fallback predicates flag/abstain (never green, never auto-dismissed),
no-silent-drop equality.
Does not restate ADR-857/550/1606; cross-references them. Resolves the
sole remaining review blocker on #1835.
