Generalizes the preferences-template-upgrade pattern to all scaffold-managed
documents with three states (pending/editing/completed), HTML-comment markers
on Markdown files, frontmatter on PREFERENCES.md, and a content-hash archive
for migrating legacy projects.
Operation is automatic-first, not command-driven:
- Synchronous on every SF startup (cheap path: missing + upgradable + legacy)
- Asynchronous after milestone completion: scaffold-keeper subagent runs the
existing records-keeper skill, treating code as the source of truth and
re-deriving doc content from source when drift is detected
- Surfaces results via the structured-notification model (kind:approval_request)
only when human review is warranted; silent runs produce no notification
- Manual /sf scaffold sync exists as an escape hatch for dry-run + forced
refresh, not as the primary interface
Five implementation phases (A-E), each independently shippable. Phase A
unlocks the architectural property; Phase D is what makes records-keeper
autonomous for code-derived docs.

Phase 1 — close SF-side polish gaps:
- codebase-generator: distinguish uv/poetry/pdm in Python stack-signals;
surface configured tooling (ruff/mypy/pyright) when config files exist
- doctor-environment: new checkPythonEnvironment — detects uv/poetry/pdm
via lockfile, verifies binary on PATH, warns with install hint when missing
- doctor-environment: new checkSiftAvailable — recommends sift install for
repos > 5000 source files when not on PATH
- tech-debt-tracker: documented future memory-as-sub-extension extraction
(defer until real backend-swap requirement)
Phase 2 — internal wire architecture:
- ADR-020: singularity-grpc as shared schema repo; gRPC + typed clients
for first-party services; MCP façade only at external-tool boundary
- ADR-019: trimmed MCP scope section to a 3-line summary linking to ADR-020
to avoid the wire-format table living in two places
- design-docs/index.md: ADR-020 added to ADR table
These changes make SF stronger for autonomous work on Python repos
(particularly ace-coder) and capture the internal wire architecture
decision as a durable ADR before any singularity-grpc code lands.

Adds __pycache__, .pytest_cache, .mypy_cache, .ruff_cache, .tox, .eggs,
and htmlcov to RECURSIVE_SCAN_IGNORED_DIRS so SF doesn't walk into them
when scanning project files. These directories can contain thousands of
files in mature Python projects and were slowing down detection / scan
operations on Python codebases.

ADR-019 framing corrections:
- SF is single-machine, single-user, single-repo by design — character, not
limitation. Stays a standalone app permanently; does not get absorbed into ACE.
- Phase 6 reframed: "pattern transfer" not "orchestration convergence." ACE
ports patterns from SF, both apps remain independent.
- Phase 2 reframed: SF stays local. Federation is an ACE concern; SF doesn't
wire memory-store remote-mode against singularity-memory.
Detection strengthened for Python (priority for ace-coder work):
- Detect uv / poetry / pdm and prefix verification commands accordingly
- Emit ruff check when configured (file or [tool.ruff] in pyproject.toml)
- Emit mypy / pyright when configured — skip when no config to avoid false fails
- pyprojectHasTool helper for [tool.<name>] section detection
Detection strengthened for Rust:
- cargo fmt --check (fastest, catches style first)
- cargo check (type-only, faster than test)
- cargo clippy -- -D warnings (warnings as errors)

Internal services (SF↔memory, ACE↔memory, SF↔ACE) talk via typed direct
clients generated from the Go/TS APIs — HTTP/gRPC for memory, existing
JSON-RPC stdio for SF↔ACE. MCP is reserved for external LLM-driven coding
tools (Claude Code, Cursor) that don't share our build system; it is a
scaffold for the period when external coders help build the platform and
shrinks as the system becomes self-hosting.
Adds an explicit "MCP scope" table so the rule is stated once. Updates the
three-layer architecture diagram, Phase 2, and Phase 6 to remove the
inaccurate "all consumers over MCP" framing.

Captures the SF↔ACE incremental convergence strategy: workspace VMs
(Firecracker) as the unified execution isolation primitive, the three-layer
architecture (orchestration/knowledge/execution), the 6-phase convergence
path, and ADR-014 Phase 4 cancellation (persistent-agent runtime reassigned
to ACE). Cross-references the matching ACE document at
docs/architecture/sf-ace-convergence.md.

When metadata is present, skip the text fallback entirely — the emitter
declared the event kind explicitly and the regex should not override it.
Add regression test file covering all acceptance criteria: metadata-first
classification, legacy fallback, dedupe_key dedup, and the key invariant
that automated notices cannot produce terminal/blocked signals.

Replace brittle string-matching in headless-events.ts with structured
source/kind/blocking/dedupe_key metadata on notify() events. String
matching is preserved as a fallback for the ~940 untagged call sites.
- Add NotificationMetadata type to headless-types.ts (canonical definition)
- Extend rpc-types.ts notify event with optional metadata field
- Extend ExtensionUIContext.notify() signature with optional 3rd arg
- Pass metadata through RPC notify implementation in rpc-mode.ts
- Update headless-events.ts: isTerminalNotification, isBlockedNotification,
isMilestoneReadyNotification, isPauseNotification all check metadata first
- Update notification-store.ts: store metadata on NotificationEntry; use
metadata.dedupe_key as dedup key when provided (falls back to message hash)
- Update notify-interceptor.ts to thread metadata through to store + original
- Tag critical emit sites with structured metadata:
stopAuto → { kind: "terminal" } (+ blocking: true when reason includes "block")
pauseAuto → { kind: "terminal", blocking: true }
guided-flow milestone ready → { kind: "approval_request", blocking: true }
- Update notification-overlay.ts to prefer metadata.source for [label] display
- Add 17-test regression suite (notification-event-model.test.ts)

- Add harness/ directory to SF repo (specs/, evals/, graders/ with AGENTS.md)
and seed harness/specs/bootstrap.md (agent-legibility verification)
- Extend agentic-docs-scaffold.ts: new repos get harness/ + ADR-TEMPLATE.md
and just adr / just spec / just harness-spec recipes via justfile
- Sync SF_RUNTIME_PATTERNS (gitignore.ts canonical) → git-service.ts and
worktree-manager.ts: add audit/, exec/, model-benchmarks/, reports/,
notifications.jsonl, routing-history.json, self-feedback.jsonl, repo-meta.json,
and milestone continue-marker patterns
- Inject ARCHITECTURE.md into system prompt via loadArchitectureBlock() in
system-context.ts (capped at 8 000 chars, after KNOWLEDGE block)
- Write real ARCHITECTURE.md for this repo (system map, .sf/ layout, key flows)
- Add ADR-TEMPLATE.md to docs/design-docs/

Gitignore (core change):
- Remove stale blanket .sf/ entries from .gitignore (migrated to
.git/info/exclude on 2026-04-29, never cleaned up)
- gitignore.ts: split SF_RUNTIME_EXCLUSION_PATTERNS into two modes —
SF_SYMLINK_EXCLUSION_PATTERNS (blanket .sf for symlink repos where
git cannot traverse the symlink) and SF_RUNTIME_EXCLUSION_PATTERNS
(granular runtime-only patterns for directory repos, enabling
.sf/milestones/ and other durable planning artifacts to be tracked)
- ensureGitInfoExclude() now detects symlink vs directory and writes
the correct patterns, handling transitions between modes cleanly
- ADR-001 status: Proposed → Accepted
Docs:
- Fill 11 placeholder scaffold docs with real SF-specific content:
PLANS, DESIGN, PRODUCT_SENSE, QUALITY_SCORE, RELIABILITY, SECURITY,
design-docs/index.md, exec-plans/active, exec-plans/completed,
exec-plans/tech-debt-tracker, records/index
- Add records note: docs/records/2026-05-01-repo-vcs-and-notifications.md
- ADR-008 status: Accepted → Proposed (deferred — not applicable to
current usage model where Claude Code assists externally, not as a
Pi provider inside SF's dispatch loop)

- Add repository-vcs-context.ts to detect and inject VCS context (Git/Jujutsu)
into the agent system prompt; wire in repo-vcs bundled skill trigger
- Add src/resources/skills/repo-vcs/ skill for commit, push, and safe-push workflows
- Add JSDoc Purpose/Consumer annotations to app-paths, bundled-extension-paths,
errors, extension-discovery, extension-registry, headless-types, headless, and traces
- Add justfile and just to flake.nix devShell
- Fill out new-user-onboarding.md spec (Draft) and core-beliefs.md (Status: Accepted)
- Add notification-event-model.md design doc and notification-source-hygiene.md spec
