engram: reconcile M8 HNSW vindex (#109) onto current dev, restore 3 fixes the branch predated
El SDK CI - dev / build-and-test (pull_request) Failing after 4m49s

Lands feat/reframe-region-setop (PR #109: native set-based reframe_region,
decorator-as-seam @route port, teacher-summon, and the M8.1 activate-latency
work — lazy-memoized cosq via eg_cosq_at + engram_vindex HNSW-accelerated
seed discovery + vindex_harvest_from_store/vindex_bench oracle) onto dev's
actual current HEAD, plus engram-tiered-storage's still-unique test suite.

RECONCILING #109 WITH engram-tiered-storage (M4-M10 HNSW/geometry/reason/
verify work): not a two-way merge. engram_vindex.c's HNSW core (search_layer/
select_neighbors/prune_links/insert) is BYTE-IDENTICAL between the two
branches; #109's copy is a strict superset (adds vindex_harvest_from_store,
used by vindex_bench.c's brute-force-vs-HNSW oracle). engram_reason.c and
engram_verify.c are also byte-identical. #109's own branch point already
carried engram-tiered-storage's M4-M10 lineage forward, so there was nothing
left to merge into #109 for those files. The one thing engram-tiered-storage
had that #109's tree dropped: its full test suite (test_vindex.c,
test_geometry.c, test_reason.c, test_verify.c, test_m7_traversal.c, the
interoception P0-P5 tests, bufpool/compaction tests, and their run_*.sh
harnesses) — ported over here unchanged.

WHY THIS NEEDED HAND RECONCILIATION, NOT A MECHANICAL MERGE: #109's branch
forked from dev on 2026-08-14 15:40 (before restructure-adjacent history
diverged the file's merge-base for `git merge` — it presented as an add/add
conflict). A straight two-dot diff (dev tip -> PR tip) applied cleanly, but
it silently reverted THREE dev fixes landed on 2026-08-14/15, after the
branch point, that the PR's diff had no way to know about:

  1. qgate rescale (2026-08-14 self-review): PR's lazy eg_cosq_at rewrite of
     the query-aware propagation gate dropped the shift-and-floor rescale
     about ENGRAM_EMBED_S0 (measured: unrelated-pair median 0.562->raw gate
     0.67, i.e. "a small tax, not a gate"). Restored the rescale, wrapped
     around the lazy accessor -- the PR's actual improvement (WHEN cosq[oi]
     is computed) is orthogonal to WHAT it gates on and both are kept.
  2. Eviction cause decomposition (2026-08-14 self-review): dev decomposes
     wm_evicted into evict_floor/evict_cap/evict_bll so WM churn is
     diagnosable (identity: evicted == floor+cap+bll+dup_wm+dup_wm_global).
     PR's tree predates this and dropped all three counters + their JSON
     stats fields. Restored declarations, all 4 direct increment sites, the
     eg_wm_carry_over bll increment, and the act-stats JSON fields --
     alongside (not instead of) the PR's own P4 afferent / API-reshape
     counters already in that same struct/JSON.
  3. Hebbian link-formation selection (2026-08-15 self-review, TODAY): dev
     selects the STRONGEST qualifying candidate for consolidation each call;
     PR's tree predates this and reverted to hash-slot order (arbitrary wrt
     association strength) for edge formation -- the one path that writes
     PERMANENT structure. Restored the strongest-candidate while-loop,
     keeping the PR's own genuine improvement at that site
     (engram_adj_on_edge_added incremental-index append instead of a bare
     adj_dirty=1 full-rebuild flag).

engram/src/server.el's 3-way conflicts (autoconnect_on/ise_offgraph_on env
flags, /api/nodes connected-count in responses) were pure additive: dev's
side was empty, PR's side added the feature. Took PR's side whole.

VERIFIED (nsbx sandbox only, live :8742/:7770 never touched):
  - cc -std=c11 -O2, clean link against the real engram/src/server.el via
    elc, zero errors.
  - vindex_bench (built standalone, read-only harvest) against the real
    production store clone (13,671 embedded nodes, 768-dim nomic-embed-text):
    recall@10 = 1.0000 at ef 64/128/200; HNSW search 0.28-0.79ms/query vs
    2.03ms/query brute-force oracle (2.6x-7.2x). HNSW build itself: 46.5s
    for the full 13,671-node set -- see the flagged risk below.
  - Booted the reconciled binary in an isolated nsbx sandbox (:8905, cloned
    snapshot of the live store, 13,424 nodes / 37,656 edges) and called
    /api/activate for real: first call after boot 41.5s (pays the one-time
    HNSW build inline -- matches the standalone bench), second/third calls
    356ms/605ms, no crash, correct results, act-stats JSON (including the
    restored evict_floor/cap/bll fields) reads correctly.

KNOWN RISK TO FLAG BEFORE ANY LIVE CUTOVER (not fixed here; out of scope for
this dev-only land per instructions not to touch :8742/:7770): eg_vindex_sync
builds the HNSW index synchronously, inline, on the first engram_activate()
call after every process start (or index invalidation). On the real node
count that is a ~46s blocking stall on a single-threaded server -- the first
request after every restart (or its concurrent siblings) waits the full
build. Recommend a background/incremental build (or a bounded per-call build
budget) before this ever reaches the live daemon. See PR description / final
report for the fuller writeup.

/* bench_discrimination.c — M9 REFINEMENT bench: measures whether mean-centering
* the anisotropic nomic-embed-text space sharpens the §5 geometry operators on
* REAL data. Read-only over a COPY of the live store (never the live file).
*
* usage: bench_discrimination [store.egm]
* (or set ENGRAM_BENCH_STORE). If no store is given/openable it prints
* SKIP and exits 0 — so it is safe in CI without live data.
*
* It picks two semantically distinct cohorts by keyword (domain A vs domain B),
* computes the global mean over the embed-eligible set (via engram_geo_mean_build
* — the same offset the descriptor uses), then reports BEFORE (raw unit space)
* vs AFTER (mean-centered space):
* - cross-centroid cosine (lower = better separated)
* - cross-centroid Euclid dist (translation-invariant: a control)
* - intra-cohesion per domain (member cos to own centroid)
* - overlap operator (cross_cos / sqrt(intraA*intraB): ~1 = domains
* indistinguishable, ~0 = cleanly separated)
* - angular separation ratio z (centroid angle / summed angular spread)
* - mean pairwise cosine sample (the anisotropy headline; ~0.55 raw -> ~0 ctr)
*
* Pure C11; links engram_store.c + engram_geometry.c; -lm.

/* test_compaction.c — M5 gate: ONLINE COMPACTION + background checkpointer.
*
* Pure C. Build: gcc -O2 test_compaction.c ../../lang/runtime/engram_store.c -o t
* Writes ONLY under a throwaway /tmp dir. Never touches ~/.neuron or live ports.
*
* Proves:
* 1) RECLAIM — tombstone/forget a large fraction of nodes + re-put many edges
* (dead versions) + orphan large-record overflow chains, then compact:
* page count AND file size drop, yet EVERY live record survives bit-exact and
* the id + adjacency indexes resolve correctly at the relocated positions.
* 2) CRASH-DURING-COMPACTION — kill at phases 0/1/2; recovery is always a
* consistent store (crc clean, every live record intact), never corrupt.
* 3) BACKGROUND CHECKPOINTER — a low ops / WAL-bytes threshold fires a checkpoint
* automatically on the write path; the WAL prefix is reclaimed; recovery works.
* 4) POOL COOPERATION — compaction under a tiny ENGRAM_POOL_FRAMES stays correct
* with no stale frame surviving for a relocated page.

/* test_scan_collision.c — regression gate for the "saved but not findable" bug.
*
* ROOT CAUSE UNDER TEST: store_scan_nodes / store_scan_edges (the boot-load
* path that populates the resident in-RAM graph — engram_store_boot ->
* eg_load_node_cb) deduplicated emitted records by their 64-bit id_hash
* (FNV-1a-64), NOT by the full id string. Two DISTINCT ids that collide under
* id_hash therefore emitted only the FIRST: the second node/edge was durably
* present in neuron.egm (store_get_node finds it), physically on a live page,
* yet was SILENTLY DROPPED from the resident load. After any store reopen it
* was unretrievable by id, absent from lexical search, and missing from the
* recent list — exactly the reported symptom.
*
* The two ids below are real FNV-1a-64 collisions (found offline via Brent's
* cycle detection over fnv1a(hex16(x))); both hash to 0x15141fdadfa24abe.
*
* Pure C. Writes ONLY under a throwaway /tmp dir. Never touches ~/.neuron.
