After 932 (review_hold register) and 933 (item_type + epic registers), the
remaining production yaml_legacy callers all had typed CRDT equivalents.
Migrated:
- agents/lifecycle.rs:
- transition_to_merge_failure writes to MergeJob.error CRDT entry instead
of YAML body. The legacy `merge_failure: "..."` front-matter write is gone.
- reject_story_from_qa inlines the QA-rejection notes append; no longer
needs yaml_legacy::write_rejection_notes_to_content.
- fields_to_clear_transform helper deleted along with all five callers —
blocked/retry_count/merge_failure are typed CRDT fields now, so clearing
the equivalent YAML keys is redundant.
- http/workflow/pipeline.rs:
- load_pipeline_state reads merge_failure from MergeJob.error (mirrors
status_tools.rs).
- validate_story_dirs checks the typed CRDT `name` register instead of
parsing YAML front matter.
- http/mcp/status_tools.rs: review_hold reads the typed CRDT register
(yaml_residue wrap was the last one in this file).
- http/mcp/story_tools/criteria.rs: story_name reads from CRDT.
- service/agents/mod.rs::get_work_item_content: name/agent come from CRDT.
- service/notifications/io/mod.rs::read_story_name: same.
- http/workflow/bug_ops/{bug,refactor}.rs: name-fallback paths drop YAML
parsing in favour of the CRDT-derived item.name.
Dead helpers removed from db/yaml_legacy.rs:
yaml_residue, write_merge_failure_in_content, write_rejection_notes_to_content,
clear_front_matter_field_in_content, write_review_hold_in_content,
clear_front_matter_field, write_review_hold (the last four shipped in 932).
Remaining surface: FrontMatter / StoryMetadata structs, parse_front_matter,
set_front_matter_field — kept for `coverage_baseline` writes via
test_results.rs and the generic update_story front_matter escape hatch.
Test fixtures rewritten to seed the CRDT register instead of relying on
YAML parsing during write_item_with_content:
- has_review_hold_returns_* tests
- item_type_from_id_uses_crdt_register_for_numeric_ids
- tool_list_epics_shows_member_rollup
- get_work_item_content (both copies — http/agents + service/agents)
- validate_story_dirs_missing_name_in_crdt
- server_side_merge_*_sets_merge_failure (assert MergeJob.error, not YAML)
cargo fmt --check, clippy --all-targets -- -D warnings, and the
2856-test suite all pass.

Replaces the YAML-only `type: epic` / `epic: <id>` front-matter fields with
typed CRDT registers on PipelineItemCrdt. The epic-mechanism MCP tools
(`tool_list_epics`, `tool_show_epic`), the epic-context injection in agent
spawn, and the type-classifier helpers (`item_type_from_id`, `is_bug_item`,
`is_refactor_item`) now all read from the CRDT.
Schema:
- PipelineItemCrdt: `item_type: LwwRegisterCrdt<String>` and
`epic: LwwRegisterCrdt<String>` registers.
- WorkItem: typed `item_type()` and `epic()` accessors returning `Option<&str>`.
- crdt_state::set_item_type(story_id, Option<&str>) and
crdt_state::set_epic(story_id, Option<&str>) typed setters.
Write paths populate the new registers:
- create_story_file / create_bug_file / create_spike_file /
create_refactor_file / create_epic_file — each calls set_item_type after
write_story_content.
- tool_update_story intercepts `epic` and `type` fields and routes them to
the typed setters (same pattern as qa / depends_on).
Read paths migrated off yaml_legacy:
- http/mcp/story_tools/epic.rs: tool_list_epics + tool_show_epic.
- agents/lifecycle.rs::item_type_from_id (numeric-only IDs).
- agents/pool/start/spawn.rs epic-context injection.
- http/workflow/bug_ops/bug.rs::is_bug_item, refactor.rs::is_refactor_item.
- http/workflow/pipeline.rs::load_pipeline_state — review_hold/qa/epic_id
all come from the CRDT now; only merge_failure is still YAML (sweep in
929 stage 10).
All `yaml_residue(...)` wraps for item_type / epic are removed; the
remaining residue marker doc no longer references 933.
cargo fmt --check, clippy --all-targets -- -D warnings, and the 2857-test
suite all pass.
