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.

title: Post-Execute Codebase Drift Detection
|
|
group: Brownfield Features
|
|
order: 27.2
|
|
---
|
|
|
|
**Introduced by:** #2003
|
|
**Trigger:** Runs automatically at the end of every `/msd-execute-phase`
|
|
**Configuration:**
|
|
- `workflow.drift_threshold` (integer, default `3`) — minimum new
|
|
structural elements before the gate acts.
|
|
- `workflow.drift_action` (`warn` | `auto-remap`, default `warn`) —
|
|
warn-only or spawn `msd-codebase-mapper` with `--paths` scoped to
|
|
affected subtrees.
|
|
|
|
**What counts as drift:**
|
|
- New directory outside mapped paths
|
|
- New barrel export at `(packages|apps)/*/src/index.*`
|
|
- New migration file (supabase/prisma/drizzle/src/migrations/…)
|
|
- New route module under `routes/` or `api/`
|
|
|
|
**Non-blocking guarantee:** any internal failure (missing STRUCTURE.md,
|
|
git errors, mapper spawn failure) logs a single line and the phase
|
|
continues. Drift detection cannot fail verification.
|
|
|
|
**Requirements:**
|
|
- REQ-DRIFT-01: System MUST detect the four drift categories from `git diff
|
|
--name-status last_mapped_commit..HEAD`
|
|
- REQ-DRIFT-02: Action fires only when element count ≥ `workflow.drift_threshold`
|
|
- REQ-DRIFT-03: `warn` action MUST NOT spawn any agent
|
|
- REQ-DRIFT-04: `auto-remap` action MUST pass sanitized `--paths` to the mapper
|
|
- REQ-DRIFT-05: Detection/remap failure MUST be non-blocking for `/msd-execute-phase`
|
|
- REQ-DRIFT-06: `last_mapped_commit` round-trip through YAML frontmatter
|
|
on each `.planning/codebase/*.md` file
