 ### Current Status Summary
 
-As of Day 16 (2026-02-24), the project has **~144 closed issues out of ~259 assigned issues** across all milestones (72% overall completion rate). The foundational layers — domain models, persistence, YAML schemas, CLI commands, quality automation, and CI/CD — are substantially built out. Today's progress includes the **actor compiler** (Jeff, #158 merged — YAML to LangGraph StateGraph compilation), **agent skills discovery** (Jeff, #161 merged), **actor CLI alignment** (Jeff, #288 merged), **CLI plan/action extensions** (Jeff, #325 merged), and a **database parallelism fix** (Brent, #418 merged).
+As of Day 18 (2026-02-26), the project has **~168 closed issues out of ~225 assigned issues** across all milestones (~75% overall completion rate). A major productivity surge over Days 16-18 closed **65 issues in 3 days**, substantially advancing M1, M2, M3, and M4. The foundational layers — domain models, persistence, YAML schemas, CLI commands, quality automation, CI/CD, validation pipeline, and security hardening — are now mature.
 
-The primary blocker for M1 completion remains the **sandbox merge/apply pipeline** (#155, Luis — active branch) and the **E2E source-code smoke test suite** (#156, Brent). The M2 blockers are the **MCP adapter** (#159, Aditya — in review) and remaining **actor YAML extensions** (#157, Aditya — active branch). The actor compiler (#158) — previously the M2 critical-path blocker — was merged today.
+**Days 17-18 highlights**: Apply pipeline + validation-gated apply + diff review merged (Luis, PR #417 — #155, #175, #176, #178, #303, #186). Changeset persistence (Jeff, #163). Plan resume + concurrency locks (Jeff, #327, #328). Provider cost controls (Jeff, #324). Decision persistence (Hamza, PR #131 — #171). Async resource cleanup (Hamza, #321). Actor YAML hierarchy (Aditya, PR #432 — #157). Security hardening — template rendering + exception handling (Hamza, #319, #320). Brent QA batches: M1/M2 E2E suites (#156, #169, #326, #402, #403) and M3/M4 E2E suites (#179, #180, #404, #405, #187). CI concurrency groups (#452).
 
-!!! warning "Schedule Risk: 7-9 Days Behind"
+**M1 is essentially complete** — only #323 (remove FakeListLLM defaults) remains open. The M2 blockers are the **MCP adapter** (#159, Aditya), **agent skills loader** (#160, Aditya), and **skill persistence/CLI** (#166, #167, #168). The M3 target date is today; 3 issues remain (#172 decision recording, #173 invariant enforcement, #174 plan explain CLI).
 
-    The project is running **7-9 days behind** the original aggressive schedule. M1 (target Feb 15) is overdue by 9 days; M2 (target Feb 22) is overdue by 2 days. A major workload rebalancing from Luis (33 remaining issues, lowest velocity) to Jeff (highest velocity, capacity available) is being executed to close the gap. Any `MoSCoW/Could Have` items in M1-M2 should be deferred to avoid further slippage.
+!!! warning "Schedule Risk: 5-7 Days Behind (Narrowing)"
+
+    The project is running **5-7 days behind** the original aggressive schedule, improved from 7-9 days at Day 16. The 65-issue closure burst over Days 16-18 substantially narrowed the gap. M1 (target Feb 15) is overdue by 11 days but essentially complete. M2 (target Feb 22) has 6 remaining issues. M3 (target Feb 26) has 3 remaining issues. The workload rebalancing executed on Day 16 is paying off — Jeff's throughput has been exceptional, and the validation/security batch from Luis/Hamza landed cleanly.

 ### What Remains To Be Done
 
 The majority of the specification's domain models, services, CLI commands, and infrastructure modules are now implemented. The following areas still require completion or have only partial implementations:
 
-- **MCP runtime adapter**: Live connection to MCP servers for external tool discovery and invocation at runtime. Aditya has active work on `develop-aditya-2` branch with PR #382 in review. Schema and domain models exist; the runtime bridge is pending. **This is the remaining M2 critical-path blocker** (actor compiler was merged 2026-02-24).
-- **Decision persistence**: Hamza has active work on `feature/m4-decision-persistence`. The domain model and context snapshots are now merged; the database persistence layer (tables, repositories, CRUD) is next.
-- **Decision recording service**: Wire decision recording into the strategize/execute phases so decisions are automatically captured during plan execution.
-- **Validation runner pipeline**: A dedicated module for executing required and informational validations attached to resources, with pass/fail gating on the apply phase.
+- **MCP runtime adapter**: Live connection to MCP servers for external tool discovery and invocation at runtime. Aditya's previous PR #382 merged the foundation; the agent skills loader (#160) and MCP adapter runtime (#159) remain. **This is the remaining M2 critical-path blocker.**
+- **Decision recording service**: Wire decision recording into the strategize/execute phases so decisions are automatically captured during plan execution (#172, Hamza).
+- **Invariant enforcement**: Runtime enforcement of invariant constraints with scoped precedence and reconciliation (#173, Jeff).
+- **Plan explain CLI**: Plan tree and explain commands for decision tree visualization (#174, Hamza).
+- **Skill persistence and CLI**: Persist flattened tool sets (#166, Jeff), skill CLI commands (#167, Aditya), MCP refresh hooks (#168, Aditya).
 - **Estimation actor logic**: The `estimation_actor` field is plumbed through Plan, Action, CLI, and service layers, but no actual estimator implementation exists to compute cost/risk estimates before execution.
 - **ACMS v1 full pipeline**: Context policy with phase-scoped views and the context service exist. Still pending: Universal Knowledge Ontology (UKO) with RDF-based resource representation, Context Request Protocol (CRP), pluggable context strategies, the full ten-component Context Assembly Pipeline, and hot/warm/cold tiered storage with per-actor scoped views.
 - **Large-project context management**: Indexing 10,000+ file codebases with bounded memory context assembly, skeleton compression for parent-to-child context propagation, and performance validation at scale.
-- **Sandbox merge/apply with validation gating**: The apply service exists but needs validation gating hooks and conflict resolution for the sandbox merge pipeline.
-- **E2E smoke test suites**: Per-milestone E2E verification suites (#402-#407) need to be written to validate milestone success criteria.
+- **E2E smoke test suites**: M5 (#406) and M6 (#407) E2E verification suites remain. M1-M4 suites are complete.
+- **FakeListLLM default removal**: Provider defaults cleanup (#323, Jeff).
 
 The following areas are substantially implemented and are no longer blocking:
 
 - Resource abstraction (types, registry, handlers with git-checkout and fs-directory, DAG metadata, CLI)
 - Sandbox strategies (git_worktree, copy-on-write, no-sandbox, factory, merge)
 - Tool system (runner, registry, built-in file/git/changeset tools, schema validation, lifecycle, router)
-- Security hardening (config scanner, sandboxed Jinja2 templates, input validation, credential redaction, secrets masking)
-- Apply pipeline (plan_apply_service with diff review, merge, changeset capture)
-- Decision domain model (12 decision types, context snapshots, influence DAG, frozen model helpers)
+- Security hardening (config scanner, sandboxed Jinja2 templates, input validation, credential redaction, secrets masking, template rendering hardening, exception handling enforcement, async resource cleanup)
+- Apply pipeline (plan_apply_service with validation gating, diff review, merge, changeset capture, DoD enforcement, error recovery patterns)
+- Decision system (12 decision types, context snapshots, influence DAG, frozen model helpers, database persistence)
 - Correction engine (revert/append modes, BFS impact analysis, dry-run reporting)
 - Invariant reconciliation (domain model with scopes, merge with precedence, enforcement service)
 - Subplan orchestration (domain models for config, status, merge strategies, failure handling)
 - Phase reversion (constrained apply -> back to strategize state machine)
 - Checkpointing (CheckpointScope, profile flags, cleanup pruning, integrated throughout)
 - Automation profiles (8 built-in profiles, guard logic, 4-level precedence service, CLI commands)
-- Agent Skills loader (registry, protocol, built-in skills, SKILL.md schema support)
+- Agent Skills discovery (registry, protocol, built-in skills, SKILL.md schema support)
+- Changeset persistence (database tables, repository, diff artifact storage)
+- Concurrency controls (plan/project advisory locks, plan resume with state recovery)
+- Provider controls (cost controls, fallback routing, rate limiting)
 - LSP integration (stub modules with registry, models, tool adapter — runtime deferred to server mode)
 - Server connectivity stubs (ACP HTTP transport stub, ACP facade, local-mode routing)
 
 ### Milestone Roadmap

+#### Milestone 3: Decisions + Validations + Invariants (Target: Feb 26, ETA: ~Mar 2)
 
 **Goal**: Decisions are recorded during Strategize and Execute phases and persisted to the database. Users can view the decision tree (`plan tree`), inspect individual decisions (`plan explain`), manage invariants (`invariant add/list/remove`), and correct decisions (`plan correct --mode revert|append`) with selective subtree recomputation.

 ### Schedule Risk Summary
 
-The project is currently running approximately **7-9 days behind** the original aggressive schedule. The primary causes are: (1) the scope of v2-to-v3 architectural transition was larger than anticipated, requiring significant model realignment and test rewriting; (2) CI/CD pipeline stabilization consumed more effort than planned due to container resource constraints and cross-environment compatibility issues; and (3) the execute/apply pipeline — the critical vertical slice — was deferred in favor of breadth-first foundation work.
+The project is currently running approximately **5-7 days behind** the original aggressive schedule, narrowed from 7-9 days at Day 16. The primary causes of the original delay were: (1) the scope of v2-to-v3 architectural transition was larger than anticipated; (2) CI/CD pipeline stabilization consumed more effort than planned; and (3) the execute/apply pipeline was deferred in favor of breadth-first foundation work.
 
-The gap is expected to **narrow** in later milestones because: (a) foundational infrastructure (persistence, CLI patterns, quality gates, domain models) is now solid and reusable; (b) aggressive workload redistribution on Day 16 moved 25 issues from slower developers (Luis, Hamza) to Jeff (highest velocity), reducing bottleneck risk; and (c) each subsequent milestone builds on proven patterns rather than establishing new ones. Actor compiler merging today unblocks actor-dependent work across M2-M4.
+The gap has been **actively narrowing** since Day 16: (a) the workload redistribution moved 25 issues to Jeff and paid off with a 65-issue closure burst over Days 16-18; (b) the validation pipeline, apply pipeline, security hardening, and decision persistence all landed in a concentrated 2-day window; (c) M1 is essentially complete and M2/M3 are close behind with only 6 and 3 issues remaining respectively; (d) Brent's QA batch merges (M1-M4 E2E suites) eliminated the testing backlog through M4.
