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.
* test(#1884): reproduce phantom lock timeout from swallowed mkdir failure
withPlanningLock swallows a platformEnsureDir failure at src/planning-workspace.cts:210,
so an EACCES/ENOSPC/EROFS creating .planning/ is misreported as a 10s "held by a live
process" lock-contention timeout instead of the real filesystem error. These tests pin
the corrected contract and currently fail against the unfixed source (RED). Also proves
the pre-existing Docker overlay-fs lock-write retry race is unaffected by this change.
* fix(#1884): surface mkdir failures instead of a phantom lock timeout
withPlanningLock swallowed platformEnsureDir failures (EACCES/ENOSPC/EROFS/EMFILE)
creating .planning/, so the subsequent lock write failed with ENOENT (parent
missing), which is retryable (PLANNING_LOCK_RETRY_ERRNOS, added for a Docker
overlay-fs race). The loop then spun the full 10s budget and threw a phantom
"held by a live process" contention error pointing at a nonexistent holder.
The mkdir failure now propagates immediately with its real errno and message.
The Docker overlay-fs ENOENT lock-write race (directory present) is unaffected,
as is every path where .planning/ already exists or is creatable.
Per docs/adr/1411-resolution-provenance.md's 2026-07-26 amendment, this is the
one site in epic #1879 that legitimately throws (ADR-227's genuinely-fatal
carve-out) -- its defect was throwing the wrong error after swallowing the
real one, not that it threw at all.
