All epoch timestamp fields (timestamp, last_replayed, created_at on
nodes; timestamp on relations) are now i64. Previously a mix of f64
and i64 which caused type seams and required unnecessary casts.
- Kill now_epoch() -> f64 and now_epoch_i64(), replace with single
now_epoch() -> i64
- All formatting functions take i64
- new_node() sets created_at automatically
- journal-ts-migrate handles all nodes, with valid_range check to
detect garbage from f64->i64 bit reinterpretation
- capnp schema: Float64 -> Int64 for all timestamp fields
schema_fit was algebraically identical to clustering_coefficient
(both compute 2E/(d*(d-1)) = fraction of connected neighbor pairs).
Remove the redundant function, field, and metrics column.
- Delete schema_fit() and schema_fit_all() from graph.rs
- Remove schema_fit field from Node struct
- Remove avg_schema_fit from MetricsSnapshot (duplicated avg_cc)
- Replace all callers with graph.clustering_coefficient()
- Rename ReplayItem.schema_fit to .cc
- Query: "cc" and "schema_fit" both resolve from graph CC
- Low-CC count folded into health report CC line

QueryResult carries a fields map (BTreeMap<String, Value>) so callers
don't re-resolve fields after queries run. Neighbors queries inject
edge context (strength, rel_type) at construction time.
New public API:
- run_query(): parse + execute + format in one call
- format_value(): format a Value for display
- execute_parsed(): internal, avoids double-parse in run_query
Removed: output_stages(), format_field()
Simplified commands:
- cmd_query, cmd_graph, cmd_link, cmd_list_keys all delegate to run_query
- cmd_experience_mine uses existing find_current_transcript()
Deduplication:
- now_epoch() 3 copies → 1 (capnp_store's public fn)
- hub_threshold → Graph::hub_threshold() method
- eval_node + eval_edge → single eval() with closure for field resolution
- compare() collapsed via Ordering (35 → 15 lines)
Modernization:
- 12 sites of partial_cmp().unwrap_or(Ordering::Equal) → total_cmp()
Sections within a file have a natural order that matters —
identity.md reads as a narrative, not an alphabetical index.
The position field (u32) tracks section index within the file.
Set during init and import from parse order. Export and
load-context sort by position instead of key, preserving the
author's intended structure.
