v1.2.0

Added

• Six ranking changes ship behind MEMRAIN_RANK_* flags, all off by default:
  METADATA_GATE (metadata boosts only when a lexical arm voted),
  ENTITY_TRUTH_SOFT, KEYWORD_OR_RETRY (OR keyword pass when the vector arm
  is empty), PAGE_FUSION (fusion per page instead of per chunk),
  KEYWORD_CONFIDENCE and EXACT_LOOKUP. With every flag off results and
  cache keys are unchanged. Operators also get meta.confidence
  (strong, moderate, weak, or unknown on a cache hit).
• memrain eval A/B runs flip env per query, interleave the two sides,
  record latency and report per-metric deltas with cluster sign-flip
  p-values and Holm correction. Qrels gain dev/sealed splits, clusters and
  expected_top1; a sealed run needs a preregistration and runs once.
  memrain eval qrels build writes private qrels from stored eval queries.
  docs/eval/PREREG-TEMPLATE.md describes a ranking decision.
• Links to pages that do not exist yet are remembered and reconnected when
  the page is created, restored or renamed; wanted_pages lists them.
• A capped links-stale cycle phase re-extracts pages when the link extractor
  version or the link switches change (MEMRAIN_LINKS_STALE_MAX_PER_CYCLE,
  default 200, 0 off).
• context_pack entity cards list up to 8 newer mentions
  (MEMRAIN_CONTEXT_NEWER_MENTIONS=0 turns this off).
• code_def, code_callers, code_refs, code_callees, code_blast and
  code_flow take lang; mentions carry language, kind and line range;
  code_callees accepts a symbol name. A code-graph doctor check reports
  code documents without definitions and stale unresolved edges.
• MEMRAIN_SEARCH_SNIPPET_CHARS caps each search/query hit to that many
  characters with a pointer to page_get (default 0, unchanged).

Fixed

• code_blast and code_flow returned nothing for class methods because
  call edges store the callee as written; walks now match bare or qualified
  names, stay in one language, read only live visible documents and suggest
  names on a miss. Go pkg.Fn() calls and this.repo.save() delegations
  become edges, and map.get is no longer an HTTP sink. Edges are written in
  the document's transaction.
• Graph reads (graph_neighbors, graph_query, traverse_graph,
  get_links, relational recall) no longer return deleted, archived or
  quarantined pages. Verb inference no longer types former roles or board
  seats as employment.
• memrain eval gate fails on query errors and on latency above
  --max-latency-x (default 2.0); A/B receipts no longer count as the
  nightly probe snapshot.
• Jobs pass their abort signal to agent model calls. Daily-cap refusals that
  clear at midnight defer the job instead of spending retries; permanent ones
  fail it. Background mirrors are charged to the client that wrote the page,
  under its cap.
• secrets audit scans slugs and fails when a rewritten page's search mirror
  could not be refreshed.
• Chunks that Bedrock rejects for their content stop blocking the embed-gaps
  phase after three attempts (migration 140); infrastructure errors no longer
  count against a chunk.
• JSON-RPC batches and add_fact items count against both rate limiters.
• Quarantined content no longer feeds atoms, facts backfill, on-write fact
  extraction, reflections, thin-page enrichment or drift.
• With MEMRAIN_OWNER_ENTITY set, a user claim that opens with a known
  person or company is filed on that entity.

Migrations

• 135 eval_snapshots.kind, 136 wanted_links, 137 index on
  code_edges_symbol.from_symbol_qualified, 138 index on
  reverse(documents.source_path), 140 chunks.embed_failures.
