Initialize direction from the two most spectrally separated seeds
instead of relying on input order (which was alphabetical from
BTreeMap). Run 3 rounds of power iteration with normalization
instead of 1 for better convergence.

Three new composable search stages:
confluence — multi-source spreading activation. Unlike spread (which
takes max from any source), confluence rewards nodes reachable from
multiple seeds additively. Naturally separates unrelated seed groups
since their neighborhoods don't overlap. Params: max_hops, edge_decay,
min_sources.
geodesic — straightest path between seed pairs in spectral space.
At each graph hop, picks the neighbor whose spectral direction most
aligns with the target (cosine similarity of direction vectors).
Nodes on many geodesic paths score highest. Params: max_path, k.
manifold — extrapolation along the direction seeds define. Computes
weighted centroid + principal axis of seeds in spectral space, then
scores candidates by projection onto that axis (penalized by
perpendicular distance). Finds what's "further along" rather than
"nearby." Params: k.

Replace O(n²) Vec::contains + sort/dedup with O(n) HashSet for orphan
node tracking in health_report(). Use imported HashMap type instead of
fully-qualified std::collections::HashMap.
- New agents/transcript.rs: shared JSONL parsing for enrich, fact_mine,
and knowledge (was 3 separate implementations, ~150 lines duplicated)
- New best_match() and section_children() helpers in neuro/rewrite.rs
(was duplicated find-best-by-similarity loop + section collection)
- Net -153 lines
- Replace `pub use types::*` in store/mod.rs with explicit re-export list
- Make transcript_dedup_key private in agents/enrich.rs (only used internally)
- Inline duplicated projects_dir() helper in agents/knowledge.rs and daemon.rs
Replace all partial_cmp().unwrap() with total_cmp() in spectral.rs
and knowledge.rs — eliminates potential panics on NaN without
changing behavior for normal floats.
Use existing weighted_distance() and eigenvalue_weights() helpers in
nearest_neighbors() and nearest_to_seeds() instead of inlining the
same distance computation.
Move parse_timestamp_to_epoch() from enrich.rs to util.rs — was
duplicated logic, now shared.
Replace O(n²) relation existence check in init_from_markdown() with
a HashSet of (source, target) UUID pairs. With 26K relations this
was scanning linearly for every link in every markdown unit.
Move prompts_dir into Config (was hardcoded ~/poc/memory/prompts).
Replace hardcoded ~/.claude/memory paths in spectral.rs, graph.rs,
and main.rs with store::memory_dir() or config::get(). Replace
hardcoded ~/.claude/projects in knowledge.rs and main.rs with
config::get().projects_dir.
Extract apply_agent_file() from cmd_apply_agent() — separates
file scanning from per-file JSON parsing and link application.
Add util::truncate() and util::first_n_chars() to replace 16 call
sites doing the same floor_char_boundary or chars().take().collect()
patterns. Deduplicate the batching loop in consolidate.rs (4 copies
→ 1 loop over an array). Fix all clippy warnings: redundant closures,
needless borrows, collapsible if, unnecessary cast, manual strip_prefix.
Net: -44 lines across 16 files.
Replace hand-rolled argument parsing (match on args[1], manual
iteration over &[String]) with Clap's derive macros. All 60+
subcommands now have typed arguments with defaults, proper help
text, and error messages generated automatically.
The 83-line usage() function is eliminated — Clap generates help
from the struct annotations. Nested subcommands (digest daily/
weekly/monthly/auto, journal-tail --level) use Clap's subcommand
nesting naturally.
poc-daemon (notification routing, idle timer, IRC, Telegram) was already
fully self-contained with no imports from the poc-memory library. Now it's
a proper separate crate with its own Cargo.toml and capnp schema.
poc-memory retains the store, graph, search, neuro, knowledge, and the
jobkit-based memory maintenance daemon (daemon.rs).
