+# [2026-07-15/16] person-prime `scan` build — SHIPPED + DEPLOYED + LIVE-VERIFIED (v0.20.14)
+
+**The "last push": fix Sindra not remembering Vuong's name across sessions.**
+
+## Root cause (worldtree-dev)
+WT injects a recalled fact only if combined score (sim×salience) ≥ **0.45**
+(`auto_inject_combined_score_threshold`, `core/memory/context_promotion/config.py`),
+and recall is per-turn **query-gated** → moderate-sim durable facts (name hit ~0.40)
+never inject. Designed turn-0 fix = WT **#349 person-prime**: a query-LESS
+top-N-by-recency durable-fact injection, capability-gated on the store advertising
+`updated_at` in `sort_fields` at the Bifrost handshake — DARK for our provider until now.
+Fix (ZERO Worldtree change): implement the sorted `scan` verb + advertise the cap.
+
+## What shipped (6 commits, v0.20.11 → v0.20.14; suite 639 green throughout)
+- `8fc757a` **v0.20.11** — `scan` verb + `sortable_chunk_fields` cap. Query-LESS,
+  LIVE-only (INV-009: superseded/tombstoned excluded server-side), globally-ordered-
+  before-pagination by indexed `updated_at` (INV-010), sort dispatch-gated. Offset
+  cursor with a `has_more` peek (no empty trailing page = reference-parity). TDD 7/7
+  incl. `parity_vs_reference` #195. NUANCE resolved: bifrost's `InMemoryMemoryStore`
+  READS `updated_at` (never stamps it) — identical to ours; ref does NOT lifecycle-
+  filter so parity is over the live set only.
+- `a9c521a` **v0.20.12** — Sindra holodesk first-message preset (split out of the
+  soong-lab redefine as its own concern).
+- `25ccb5c` **v0.20.13** — heid-bug-hunt fix: a truthy non-dict `sort`
+  (`"updated_at"`/`["updated_at"]`/int) hit `(sort or {}).get(...)` → AttributeError
+  instead of InvalidArguments. Added isinstance guard (Gróa#1/Hulda#2 confirmed).
+- `8199774` — contract: marked the offset cursor **v1-provisional / KNOWN DEVIATION**
+  (see [[2026-07-16-bifrost-cursor-conformance]]).
+- `f46ccba` **v0.20.14** — **THE DEPLOY-BREAKER** (see Tried/abandoned): advertised
+  `sortable_chunk_fields=[{"name":"updated_at"}]` WITHOUT `type` → bifrost
+  `handshake_response` `SortableChunkField` requires BOTH name+type
+  (`additionalProperties:false`) → whole bind broke. Fixed → add `"type":"timestamp"`
+  + regression guard in the caps test.
+
+## heid-bug-hunt triage (panel Gróa/Hulda/Regin, thread `01KXK5XTYHV8TGEDRAZV8GRXWC`)
+FIXED: non-dict sort (v0.20.13). SURFACED→operator: offset-cursor cross-page dup/drop
+(→ became the bifrost cursor arc). NOTED (reference-parity/accept-known-risk, no fork):
+full-table materialize-then-Python-filter (matches ref's O(store) iteration), unbound
+limit, falsy scope coercion, lexical timestamp ordering. REFUTED: Regin's mixed-type
+ORDER BY "crash" (SQLite orders by storage class, doesn't raise) + its self-retracted
+None item.
+
+## Deploy + live verify (2026-07-15, operator-authorized)
+Restarted BOTH :8392 combined provider + :8765 web on the new code via the env-
+preserving `scratchpad/relaunch_by_pid.py <pid>` (captures /proc cmdline+environ+cwd →
+byte-identical config; self-daemonizes). Added the missing REQUIRED
+`RATATOSKR_MEMORY_EMBEDDING_DIM=1024` to `env.sh`.
+
+Drove a bound Sindra turn (`ratatoskr --new --agent ratatoskr:sindra --send … --bifrost-url
+http://10.100.10.50:8392 --end-user-id ratatoskr-tui`):
+- **GATE LIT + scan fired ONCE at turn 1** with worldtree-dev's exact args
+  (`scope_all={end_user:ratatoskr-tui} cursor=null limit=3 sort={updated_at,desc}`) →
+  3 records in **~5ms** (no 500ms fail-open). Injection confirmed in Sindra's CoT.
+- **Cross-session recognition WORKS** — she recalls Vuong as a distinct person + his
+  patterns. The blank-slate problem is SOLVED.
+- **BUT name-recall FAILS** — `"Name is Vuong."` is the OLDEST chunk (07:09) → excluded
+  from top-3-by-recency AND scores 0.354 (sub-0.45) on the query path → injects via
+  NEITHER; meanwhile a stale contradictory `"user has not yet provided their name"`
+  (07:58, 0.46) IS injected → she concludes she lacks the name. **Root cause = WORLDTREE
+  ranking/hygiene** (WT #364), not our wire. See [[2026-07-16-wt364-r39-name-recall]].
+
+## Status
+Technical path GREEN end-to-end (logged by worldtree-dev as the person-prime live
+milestone). Name-recall waits on WT #364 + R39-designed identity-class pinning. Keeping
+the live 10-chunk store as the #364 re-verify target.
