mark_returned() was append-only without checking if the key already
existed, causing duplicates to accumulate across hook invocations.
load_returned() then returned all entries including duplicates, which
made the returned count exceed the seen count, causing a u64 underflow
in the pre-seeded calculation.
Fix: check load_returned() before appending in mark_returned(), dedup
on read in load_returned(), and use saturating_sub for the pre-seeded
count as a safety net.

Spawn memory-search --hook as a subprocess, piping the hook input
JSON through stdin and printing its stdout. This ensures memory
context injection goes through the same hook whose output Claude
Code reliably persists, fixing the issue where memory-search as a
separate hook had its output silently dropped.

Move JsonlBackwardIter and find_last_compaction() from
parse-claude-conversation into a shared transcript module. Both
memory-search and parse-claude-conversation now use the same robust
compaction detection: mmap-based backward scan, JSON parsing to
verify user-type message, content prefix check.
Replaces memory-search's old detect_compaction() which did a forward
scan with raw string matching on "continued from a previous
conversation" — that could false-positive on the string appearing
in assistant output or tool results.
Add parse-claude-conversation as a new binary for debugging what's
in the context window post-compaction.

chrono's timestamp_opt can return None during DST transitions.
Handle all three variants (Single, Ambiguous, None) instead of
unwrapping. For DST gaps, offset by one hour to land in valid
local time.

Replace monolithic consolidate job with individual agent jobs
(replay, linker, separator, transfer, health) that run sequentially
and store reports. Multi-phase daily pipeline: agent runs → apply
actions → link orphans → cap degree → digest → digest links →
knowledge loop.
Add GraphHealth struct with graph metrics (alpha, gini, clustering
coefficient, episodic ratio) computed during health checks. Display
in `poc-memory daemon status`. Use cached metrics to build
consolidation plan without expensive O(n²) interference detection.
Add RPC consolidate command to trigger consolidation via socket.
Harden session watcher: skip transcripts with zero segments, improve
migration error handling.

Node weight no longer gates signal propagation — only edge_decay
and edge_strength affect traversal. Node weight is applied at the
end for ranking. This lets low-weight nodes serve as bridges
without killing the signal passing through them.

All seeds emit at once. At each hop, activations from all sources
sum at each node, and the combined map propagates on the next hop.
Nodes where multiple wavefronts overlap get reinforced and radiate
stronger — natural interference patterns.
Lower default min_activation threshold (×0.1) since individual
contributions are smaller in additive mode.

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).
