* bmad-spec: make the memlog canonical, SPEC.md a derived view
Replace the bespoke .decision-log.md with the shared memlog script
(_bmad/scripts/memlog.py, same location as resolve_customization.py).
The append-only memlog becomes the single source of truth; SPEC.md and
spec-authored companions are re-derived from it (plus cited sources for
raw content) on each run instead of hand-patched. This makes bmad-spec
the sole writer of the spec and lets the surrounding steps (PRD, UX,
architecture, epics) feed one spec in any order without merge drift.
- New "Memory and derivation" section: memlog canonical, SPEC.md a
projection, single-writer rule, append/init via the shared script,
no status field (terminal moments are event entries).
- Operation reads the prior memlog (not the rendered SPEC.md) as the
authority on decisions and capability IDs on update.
- Conflict-surfacing: live sources/companions that disagree on a field
are raised to the user, resolution logged as a new entry.
- Rename .decision-log.md -> .memlog.md across SKILL.md and assets.
* core: add shared canonical memlog.py in src/scripts
Single source-of-truth memlog: append-only, chronological working-memory
log for skills. Installs to _bmad/scripts/memlog.py via the existing
src/scripts sync (beside resolve_customization.py), so any skill can call
it at runtime — bmad-spec is the first consumer.
Merges the neutral API (--workspace, free-form --type/--by, generic set)
with crash-safe fsync atomic writes. No lifecycle status by design: a
memory log records completion as an event entry, never a frontmatter flag.
Also accepts --path for callers that hold the file path directly. 30 tests.
* bmad-spec: include event in memlog --type list
The documented append --type set omitted event while the next line
requires --type event for terminal moments. Align the list.
* Fix memlog Python floor and exclude tests from install
- memlog.py: add 'from __future__ import annotations' so PEP 585/604
hints stay lazy; the script runs on Python 3.8+ instead of crashing
below 3.10. Correct the requires-python header to >=3.8.
- installer.js: filter tests/, __pycache__/, .pytest_cache/, and *.pyc
out of _installSharedScripts so dev-only files never ship to users.
