fix(recall): admit hortative leftover from advice-echo sessions (P33)

[sdntsng]

Summary

P32 frozen pin was 116/180. Remaining SH miss conv-30-q57 (What advice does Gina give to Jon about running a successful business?) gold is build relationships with customers, create a strong brand image, stay positive.

The gold leftover is stored in session_7 (recency rank ~827 / 1294, past the 400-row window) and has no advice/business/running tokens. FTS ANDs advice against the echo (Got any advice…, Thanks for the advice). Hybrid previously answered starting your own business sounds awesome.

This increment (generic English, not a relationships/brand dictionary, do not drop advice):

1. Detect what/how + advice/advise queries.
2. Rank leftover-covering candidate sessions that actually mention the speech-act token plus another leftover token (campaign sessions without an advice echo are not fetched).
3. Bounded session-id fetch; admit hortative / first-person-gerund leftover that omits the speech-act/business restatement tokens.
4. Search floor + rank boost so zero-token leftover can enter top-k; leftover covering joins up to three of those lines over an awesome restatement.
5. Keep hortative episode primitives on advice queries.

Pinned skip-ingest 180: 117/180 (0.650) vs P32 116/180. Flip +1 / −0. Only gain: conv-30-q57. Groups: MH 18/33, OD 4/11, SH 65/98, temporal 30/38. Ledger: RETRIEVAL 28 / PROOF 22 / READER 7 / WRITE 4 / HARNESS 2. Run locomo-s0-diag-mh-135-p33-product-recall-s1-ebb36f. Product SHA 097c6eb, pin docs SHA f61fdac.

Live Gina advice: Building relationships and creating a strong brand image for my store is something I'm always working on; Also be sure to build relationships with your customers – let them know you care; And don't forget to stay positive and motivate others

Holds: P32 veterans stories, P31 stuffed-animal, P30 push, P28 22/22.

Changes

• internal/memory/recall.go: advice leftover covering, prefer/join hortative leftover, hybrid replace.
• internal/memory/service.go: advice-echo session fetch, directive rank floor + boost, keep hortative episodes.
• Tests: covering vs awesome/students/business-restatement; session pick requires advice echo; lexical search still keeps advice; IDF score is 0 without the floor.
• Pin: locomo-s0-diag-mh-135-p33-20260825.md, cycle-closeout P33 section, handover, benchmarks README.

Test plan

• gofmt + go vet ./internal/memory/ + go test ./internal/memory/
• Live Gina advice cites relationships and brand and stay positive (not awesome, not advice echo)
• Holds: P32 veterans stories, P31 stuffed-animal, P30 push, P28 22/22
• Skip-ingest 180 --run-prefix locomo-s0-diag-mh-135-p33 vs P32b ecb9c9: 117/180, net +1

Linear / tracking

• ENG-176 / ENG-168
• Frozen pin: P33 117/180 (097c6eb / docs f61fdac) beats P32 116/180 (cd77a74 / docs 67bac0b)

Risk / follow-ups

• Do not drop advice. Do not drop May. Do not revive P29. Do not add a host→party or advice→brand dictionary.
• 117/180 is not 80% (144) and not 90% (162). Next ranking miss with gold in store: turtle-care / Joanna writing / dinner spread. No n=1540. No LME-500. No SOTA.
• WRITE still 4 — do not merge S1–S5 compiler/answer/alias/KU (split from mixed S0 PR) #133.
