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(#1960): add failing-first RCA-branching contract + schema-invariant tests
Epic #1957 Phase 2A. Source-text-is-the-product contract tests (fishbone
>=2 categories, AND-gate, multi-cause root_cause, backward compat, reasoning
checkpoint candidate_causes+and_gate fields, debugger-philosophy single-cause
note, DEBUG template) plus behavioral schema-invariant checks on two fixtures:
two contributing causes (AND-gate yes) -> both recorded; single-cause
(AND-gate no) -> one root_cause, identical to today.
Failing-first: reference, agent edits, and template note do not yet exist.
* feat(#1960): add RCA branching (fishbone + AND-gate) to gsd-debugger
Epic #1957 Phase 2A. Guards against 5-Whys single-cause bias: before committing
root_cause, the debugger enumerates candidate causes across >=2 Ishikawa
categories (code/config/environment/data) and explicitly answers an AND-gate
question. When the AND-gate fires, every contributing cause is recorded, so a
multi-cause fix no longer recurs via the unaddressed second cause.
Resolution.root_cause may hold one OR a small set (additive; single-cause
sessions are byte-identical to today). The Structured Reasoning Checkpoint gains
candidate_causes + and_gate fields; debugger-philosophy.md adds the
single-cause-bias trap.
Full rules extracted to gsd-core/references/debugger-rca-branching.md (slim
Phase 2 routing + 2 checkpoint fields kept in the agent). INVENTORY + manifest +
agent-size baseline + install-parity goldens + AGENTS.md + DEBUG template updated.
* fix(#1960): address orthogonal review (AND-gate self-consistency, parity guard, narrowed claim, ripples)
- Reference: the collapse rule now enforces AND-gate self-consistency —
and_gate=yes with a single confirmed cause is flagged as incomplete
(return to Phase 3); a race/timing note clarifies such bugs bridge
categories; the 'byte-identical' backward-compat claim narrowed to
'root_cause shape unchanged; reasoning_checkpoint gains 2 fields in every
session'.
- DEBUG.md: stale 'five-field' mirror prose -> seven-field (parallel-surface
drift the reviewer flagged); new debug-session-management parity test pins
the field-count claim to the gsd-debugger.md YAML keys (CRLF-safe).
- Scalar-assuming consumers of set-valued root_cause updated: session-manager
compact summaries (319/332), diagnose-only return (1062), archive entry
(1216), ROOT CAUSE FOUND return (1322).
- Test: added the AND-gate-yes/single-cause invariant + fixture; rephrased the
fixture describe block honestly as a schema-invariant specification.
- Phase 2 bullet phrasing clarified ('at hypothesis formation, before the
Phase 4 commit').
* test(#1960): parity regex accepts word-form count ('seven-field' or '7-field')
* test(#1960): parity regex counts array-valued YAML keys (no inline value)
* chore(#1960): backfill changeset pr number (PR #2405)
