 ## [Unreleased]
 
-### Fixed
-
-- **Cross-actor subgraph cycle detection reads actor_ref field** (#1431): Fixed
-  `_detect_subgraph_cycles()`, `_map_node()`, and the `compile_actor()` main loop
-  in `src/cleveragents/actor/compiler.py` to read `actor_ref` from the top-level
-  `NodeDefinition.actor_ref` field instead of `node.config.get("actor_ref", "")`.
-  Because `actor_ref` is a typed, validated Pydantic field (not a key inside the
-  untyped `config` dict), the old code always returned an empty string, causing
-  cross-actor cycle detection to silently fail and leaving the system vulnerable to
-  infinite recursion at runtime. Added Behave regression tests
-  (`features/actor_subgraph_cycle_detection.feature`) and a Robot Framework
-  integration test (`robot/actor_compiler.robot`) to prevent regressions.
-
 ### Changed
 
-- **`agents session list` now displays full 26-character session ULIDs** (#10970): The Rich table
-  and Summary panel ("Most Recent" / "Oldest") previously showed only the first 8 characters of
-  each session ULID. This made the output unusable for copy-paste into `session tell`,
-  `session show`, `session delete`, and `session export`, all of which require the full
-  26-character identifier. The full ULID is now displayed in all output formats (Rich, plain,
-  JSON, YAML, table).
-
-### Security
-
-- **aiohttp upgraded to >=3.13.4 to remediate CVE-2026-34513 and CVE-2026-34515** (#1549, #1544):
-  Added an explicit `aiohttp>=3.13.4` dependency constraint to `pyproject.toml` to remediate
-  two high-severity open redirect vulnerabilities. Both CVEs affect the CleverAgents platform's
-  HTTP infrastructure including A2A server communication, tool source fetching (MCP servers,
-  Agent Skills), and agent-to-agent protocol handlers. The version floor ensures vulnerable
-  versions (<3.13.4) cannot be installed even if upstream transitive dependencies have loose
-  version constraints.
+- **Timeline dashboard updated with 2026-04-18 progress snapshot** (#10288): Added schedule adherence tables and daily milestone snapshot for April 18, covering M3-M10 status including overdue milestones (M3-M7) and in-progress milestones (M8-M10). Risk assessment shows M6 (v3.5.0) highest risk with 1,130 open issues at 18.1% completion.

CONTRIBUTORS.md

@@ -31,3 +31,4 @@ Below are some of the specific details of various contributions.
 * HAL 9000 has contributed comprehensive milestone documentation for v3.6.0 (Advanced Concepts & Deferred Features) and v3.7.0 (TUI Implementation) (PR #9903): split into sub-documents covering context strategies, LLM backends, resource types, A2A rename, container tool execution, scope chain resolution, cost/safety budgets, E2E workflow tests, code review examples, plugin architecture, TUI layout, persona system, reference/command input, session management, configuration, and TuiMaterializer integration.
 * HAL 9000 has contributed the LLMTraceRepository data-integrity fix (PR #8185 / issue #7505): replaced the unconditional `session.commit()` in `LLMTraceRepository.save()` with a dual-path implementation that respects the UnitOfWork pattern — flushing only when an external session is provided, and flushing + committing + closing when operating standalone. This eliminates premature transaction commits, loss of rollback capability, and a docstring/implementation mismatch.
 * HAL 9000 has contributed the ACMS Index Data Model and File Traversal Engine (PR #9664 / issue #9579): foundational data structures for indexed context entries with hot/warm/cold/archive storage tier classification, tag system, and a timeout-safe chunked file traversal engine for large projects with 10,000+ files.
+* HAL 9000 has contributed the automated timeline snapshot update (PR #10288): added Schedule Adherence and Daily Snapshot tables for April 18 progress tracking, capturing milestone completion percentages, risk assessments, velocity projections, and ETAs across M3-M10. Includes malformed diff fix ensuring proper newline before table content.$
