2.0.0 — Session Job Lifecycle (L-01)

Agents Remember 2.0.0

A major, breaking release: the session job lifecycle (L-01) becomes the primitive the coordinator routes into, the chat and heavy task workflows are retired in favor of light tasks + master/sub-task composition, and the skill tree is flattened. Read this before upgrading — some public contracts changed.

Highlights

• L-01 session job lifecycle — every session runs orient → ground → frame → decide → build → close. The job type (bug / feature / triage / research) is a framing lens, not a gate; the only task-format call is L-01's build-mode step: read-only exit, chat build (worktree, no task file), or a durable W-02 task.
• Retired the chat (W-03) and heavy (W-01) workflows — W-03's doctrine is migrated and modernized into L-01; W-01 is replaced by a W-02 master + light sub-task series (one wrapper folder, flat numbered sub-tasks, one shared worktree, a commit per slice, one release).
• Flat skills — U-01-core-skills is dissolved; every skill sits directly under skills/, and the installer simply copies the flat tree (no tree/namespace layout).
• Post-merge ledger automation — C-11 carryover now maps the PR merge commit, so a worktree based off a freshly-merged gated branch no longer blocks on a manual ledger reconciliation.

Breaking changes

• Removed skill IDs: W-01-heavy-task-workflow, W-03-chat-task-workflow (and the heavy phase skills).
• skills_install no longer accepts a layout input — the installer is a flat copy.
• WorkflowKind drops the heavy / heavy-task values.

Upgrade

Reinstall the MCP (uvx --refresh, or pin agents-remember-mcp==2.0.0) and restart the harness, then re-run skill install (with overwrite) so the flat skill set replaces the old layout. Existing memory and onboarding are unaffected.
