Live hook: ARBORIST_NLI_SHADOW=1 makes query() surface the verifier-input text (gated off-by-default, never a cache_key/governance/audit_mode input); qa_sweep.py carries it + the answer into bench rows; the shadow sweep reads them and buckets by audit_mode. ARBORIST_NLI_SHADOW=1 make bench-qa-smoke (15 cells) → the naive 'NLI on every context clause' scaffold has a ~30% would-demote rate on STRICT answers — a haystack / multiple-comparisons artifact (real contexts segment into 100-336 clauses; max-over-all almost always finds a tangential clause the model reads as contradicting; a paraphrased STRICT answer often isn't verbatim- entailed by any single clause so the entailment guard doesn't rescue it). Lesson: the §7 #5 'candidate source clauses' + recombination-risk gating is load-bearing, not optional. Do NOT enable runtime NLI demotion on the current scaffold; next step is the candidate-clause restriction, then re-run, then gate item 4 is meaningful. Production verifier unchanged; falsification-hard stays 10/12.

# Arborist tickets — index
|
||
|
||
Arborist uses a flat `ticket-NNNNNN-<slug>.md` convention for actionable
|
||
proposals: defects with a known root cause, design proposals awaiting
|
||
go/no-go, or scoped enhancements queued for future implementation.
|
||
|
||
## Convention
|
||
|
||
- **Filename:** `docs/tickets/ticket-NNNNNN-<slug>.md`. The ID is a six-digit
|
||
zero-padded integer; the slug is hyphen-lowercase and short enough
|
||
to stay readable on a 100-column terminal.
|
||
- **Numbering:** monotonic, never reused. Pick the next free integer
|
||
greater than every existing ticket. The current next ID is on the
|
||
`Next ID` line below; bump it when you open a ticket and commit
|
||
the bump in the same commit as the new ticket file.
|
||
- **Header:** every ticket starts with
|
||
```
|
||
# Ticket #NNNNNN — <short title>
|
||
|
||
**Status:** open · awaiting go/no-go (or "in progress", "closed")
|
||
**Opened:** YYYY-MM-DD
|
||
**Scope:** <one-liner — what this ticket is for>
|
||
**Audience:** <who reads this>
|
||
**Hard constraint:** <invariants this ticket commits to NOT break>
|
||
```
|
||
- **Body:** problem statement, design choices with trade-offs,
|
||
recommendation, implementation sketch, scope boundaries, status.
|
||
See `ticket-000001-retrieval-keywords-audit-gap.md` for a worked
|
||
template.
|
||
- **Closure:** when a ticket lands, flip Status to `closed · landed in
|
||
commit <sha>` and leave the file in place. Do not delete tickets;
|
||
they are the design log.
|
||
|
||
## Distinction from other docs
|
||
|
||
`docs/` also contains architecture references and bench journey notes
|
||
that are NOT tickets — they describe state of the world rather than
|
||
proposing change. Examples that stay un-numbered:
|
||
|
||
- `seven-point-program.md` (north-star architectural directive
|
||
distilled 2026-05-01; every new ticket / feature / prompt edit
|
||
walks past this; bench harness reports per-mode directive
|
||
coverage)
|
||
- `cti-architecture.md` (architecture reference for the Clause
|
||
Tree Intelligence claim-lattice-pointer mode)
|
||
- `mesh.md` (mesh wire format + group-key state machine)
|
||
- `benchmarks.md` (bench harness orientation — fixtures, signal
|
||
floor, make targets, bench-row schema, addenda index; read
|
||
first when running a bench)
|
||
- `bench-maxing.md` (bench discipline — 5pp signal floor, n=3
|
||
default, avoid negation in prompts, honest verdicts over
|
||
optimistic ones)
|
||
- `qa-modes-bench.md` (rolling bench-journal addenda with
|
||
cross-references to per-ticket bench data)
|
||
- `soft-hash-channel-analysis.md` (analysis doc closing #000018
|
||
open questions §9.1 / §9.2 / §9.3; companion to
|
||
`soft-hash-channel-t3-bound.md`)
|
||
- `soft-hash-channel-t3-bound.md` (#000036 formal derivation of
|
||
the per-window covert-channel budget; companion to the analysis
|
||
doc, both feed the t3_bound_calculator)
|
||
- `tool-action-dag-design.md` (research path for an action-
|
||
provenance layer downstream of `final_label`. Captured pre-ticket
|
||
per the 2026-05-07 arborist-vs-donto comparison; promotes to a
|
||
ticket when an actual agent use case surfaces)
|
||
- `warrant-substrate-cookbook.md` (architecture reference for the
|
||
18 open-licensed textbook substrates backing every claim-pack
|
||
record, written 2026-05-10 after the 18/92 → 92/92 push under
|
||
`#000031`. Per-pillar substrate map, ingest patterns, alias
|
||
discipline, cascade tuning, honest tier breakdown.)
|
||
- `calculator-test-patterns.md` (architecture reference for
|
||
testing calculator / probe-style code. Twelve patterns split
|
||
into two tiers: the original 9-item core (KAT regression,
|
||
hand-computed formula assertions, monotonicity, closure /
|
||
sum-of-parts invariants, parametrized invalid-input cones, CLI
|
||
subprocess, doc parity, module-export shape) plus three
|
||
domain-specific contract pins (projective-contract for one-way
|
||
canonicalizers, dispatch-order pin for Python type-hierarchy
|
||
gotchas, tie-breaking-rule pin for banker's rounding).
|
||
Codified 2026-05-10 from the original three-module pattern
|
||
bench across `t3_bound_calculator` / `phi_alignment_probe` /
|
||
`anchor_prg`; extended same day with the four π* kernel
|
||
exemplars (`pi_star_arithmetic` / `_logic` / `_code` /
|
||
`_time_series`). Explicit "doesn't apply to verifier-style
|
||
code" caveat.)
|
||
- `lexical-first-rationale.md` (positioning/architecture reference
|
||
for why lexical-first FTS5 + content-addressed Merkle proofs is
|
||
arborist's *default* retrieval and dense-vector semantic search is
|
||
an opt-in additive layer: arborist's per-document ingest is
|
||
~10-100× cheaper than building a vector representation — same
|
||
SQLite substrate, different philosophy — which is the difference
|
||
between "ingest + search runs on a phone" and an NPU hand-warmer.
|
||
Generalizes the "soft hash vs hard hash" discipline; the numbers
|
||
come from #000039 §14.6. Written 2026-05-12.)
|
||
|
||
If a doc proposes change AND awaits a decision AND has scoped
|
||
implementation cost, it's a ticket. Otherwise it's reference.
|
||

|----------|------------------------------------------------|-----------------------|------------|-----------|
|
||
| #000051 | Federated vecpack distribution (gossip the embedding backfill) | open · awaiting go/no-go · doc-only scaffold. Makes `chunk_vecs` a distributable artifact: backfill once on any CPU box (cloud / Prometheus-Σ sweep — #000037 §3.1), publish a **vecpack** `(shard_root, vec_backend_version, [(leaf_hash, embedding_blob)…])` over the mesh wire layer, every peer pulls + bulk-loads (sub-ms/chunk on the receiver — the laptop never runs the transformer). Keyed on `leaf_hash` (portable) not `chunk_id` (shard-local). Vecpacks are **soft data** — embeddings are `UNGROUNDED`, never proof path — so a cheap structural sanity gate (chunk exists locally w/ matching leaf_hash, right blob length for (dim,quant), finite norm, backend_version matches) suffices, no Merkle-proof-grade verification needed. Supplies #000050's prereq #1 ("a vecpack exists & is imported on the bench box", not "fox embedded the corpus locally"). GPU producer (the fast path): bge-small-en-v1.5 batched on a CUDA box (4090) ≈ 10³–10⁴ chunks/s → full 6.24M-chunk corpus in *minutes*, not days — drop a CUDA `Embedder` into `default_embedder()`; CUDA stack lives only on the producer box, never in arborist's `python+sqlite3` core. The mechanism behind whitepaper §1's "the embedding pass runs off the device". #000039 / #000050 sibling | 2026-05-12 | — |
|
||
| #000050 | Vec RRF hybrid fusion (#000039 Phase 2) | open · awaiting go/no-go · doc-only scaffold; design in #000039 §4.2 (RRF) + §8 (the gate). Wire `VecBackend` as a 5th retrieval route in `query.py`, RRF-merged (route provenance carried) with the 4 FTS5 routes; UNGROUNDED hits, additive not replacement. Phase-2 sub-items now explicit: **accept-path-5** in `_filter_by_title_relevance` (low-title-overlap vec hits survive only via a stronger span-level warrant, never similarity-score alone — else the title gate drops exactly the semantic candidates vec exists for & the bench shows no lift); **six** vec config fields fold into `governance_policy_hash` (recipe-named quant `int8sym`) **+ a cache-write guard** blocking `providence_cache` persistence for vec/hybrid runs until that's wired; **run-DAG records the vec stage** (backend version, six fields, top_k, query-embedding hash, candidate chunk_ids+distances). **Gated** on (a) a corpus backfill **distributed via #000051** AND (b) a **four-condition** recall bench (A FTS5-only / B vec-only / C RRF hybrid / D candidate-union-no-RRF) clearing the 5pp floor incl. C-beats-D, on semantic-allusion + curated + **adversarial-semantic-neighbor** fixtures (else park, vec stays opt-in `--backend vec`; if C≈D ship the union, drop RRF). #000039 follow-up | 2026-05-12 | — |
|
||
| #000049 | Attribution-aware grounding check (the recombination boundary) | open · boundary accepted · production no-go · shadow-path approved (de novo review 2026-05-13 — ticket §7) · doc-only; the home for #000048's deferred §2.3 — closing the 2 recombination over-grounds in `falsification-hard` (hard-003 Mercury / hard-005 Einstein) needs an attribution / dependency-parse or mini-NLI check, which is *not lexical* (#000048 §5). Discipline question answered: a small fixed purpose-built NLI/entailment *model* may influence `audit_mode` only as an opt-in, hash-pinned, governance-hashed, **demotion-only contradiction veto** after shadow-mode evidence (never promotes — `MODEL_ASSISTED_DEMOTION`, never `MODEL_ASSISTED_PROMOTION`). Production verifier unchanged; `falsification-hard` stays 10/12 as an honest boundary marker. Roadmap: Phase 0 (this amendment) → Phase 1 (shadow design: NLI manifest, fetch/verify, `nli_pair@v1` canonicalization, recombination-risk trigger) → Phase 2 (bench-only shadow impl, `[nli]` extra, `make fetch-nli`) → Phase 3 (demotion-only runtime, gated) → Phase 4 (mesh blob sync); §7 #12 six-condition bench gate required before Phases 2–4; if NLI ever affects `audit_mode`, `nli_policy_hash` folds into `governance_policy_hash`. **Phase-2 candidate bench done 2026-05-12** (`~/git/arborist-nli-bench/`, commits `829f9a4` + `a1cb28d`; ticket §7 #18): checkpoint-agnostic harness runs the §7 #5 clause-level algorithm over 28 synth recombination cases (incl. the 2 fixtures + harder shapes) + 26 legit cases (true summaries + near-miss decoys). 4 working candidates; `nli-MiniLM2-L6-H768` (82M, 45ms p50 CPU), `deberta-v3-base-mnli-fever-anli` (184M, 223ms), `bart-large-mnli` (407M, 259ms) all 28/28 catch · 0/26 FP with the standard θe=0.9 entailment guard; `cross-encoder/nli-deberta-v3-base` 27/28; deberta-large repo-id TODO. **Key finding: the §7 #5 two-threshold rule is load-bearing** — 3 of 4 candidates argmax-contradict 1/26 legit cases on the *wrong* source clause (competing-superlative confusion, e.g. "largest hot desert" vs "largest desert overall"); the entailment guard filters every one because another clause restates the claim → 0% guarded FP vs ~4% single-threshold. Picture: recombination is *easy* for any modern NLI checkpoint — differentiator is cost/robustness, MiniLM is the cost-pick, bart-large the threshold-robust pick. **Phase-2 shadow scaffold landed in arborist 2026-05-12** (ticket §7 #19): `arborist/qa/nli/` (manifest pins MiniLM @ a fixed HF revision + θc 0.5/θe 0.9 + 2 alternates; `ShadowNLI`/`shadow_check` lazy-imports `transformers`+`torch` behind a new `[nli]` extra, degrades to `available=False` when absent — SHADOW ONLY, never an `audit_mode` input, manifest not yet in `governance_policy_hash` per §7 #2) + `bench/scripts/nli_shadow_sweep.py` + `make bootstrap-nli` / `make bench-nli-shadow` + 16 tests. Synthetic sweep (116 records): 28/28 recombination demoted, 0/26 FP on legit summaries, 0/9 fires on already-`STRICT_SPAN`. **First real-traffic sweep** (§7 #20 — `ARBORIST_NLI_SHADOW=1 make bench-qa-smoke`, 15 cells; `query.py` surfaces verifier-input text gated off-by-default, `qa_sweep.py` carries it, `nli_shadow_sweep.py` reads it): the *naive* "NLI on every context clause" scaffold has a **~30% would-demote rate on STRICT answers** — a haystack/multiple-comparisons artifact (real contexts → 100–336 clauses; `max`-over-all almost always hits a tangential "contradiction"). Lesson: the §7 #5 "candidate source clauses" + recombination-risk gating is **load-bearing** — Phase 3 (and the next Phase-2 step) must restrict the NLI call to the clauses the lexical verifier matched and/or a deterministic recombination-risk trigger; do NOT enable runtime NLI demotion on the current scaffold. Remaining: add the candidate-clause restriction, re-run, then gate item 4 is measurable. Production verifier unchanged; `falsification-hard` stays 10/12. #000048 follow-up | 2026-05-12 | — |
|
||
| #000048 | Verifier upgrade — recombination-aware grounding + clause segmentation | **closed · 2026-05-12** — steps 2.1 + 2.4 landed 2026-05-11 (12 of 16 residual items: 4 HYBRID_ENTITY over-grounds + 8 Formulate mis-segments → `formulate-hard` 12/12, `falsification-hard` 10/12; each bench-gated, no STRICT-rate regression — 2.1's gate fired on 0 QA answers, 2.4's segmenter touched 7 of 450 lattice cells both verdict changes correct). Step 2.2 (single-clause-containment paraphrase check) attempted + reverted — catches the 2 recombination fixtures but also rejects legit cross-sentence summaries with no threshold separating the two; recombination-vs-summary isn't lexical (§5 "What we learned"). The attribution-aware path moved to **#000049** (fox 2026-05-12). 2 live-pack `expected_reason` updated HYBRID_ENTITY→UNGROUNDED; 12+ tests; `make bench-5f-falsification-hard` / `bench-5f-formulate-hard` / `bench-fork-baseline-hard`. #000046 follow-up; #000047 closed | 2026-05-11 | — |
|

| #000047 | ForkScore `_delta_*` aggregator (mean vs max vs sum) | **closed · 2026-05-11** — Option D: `WeightSet.delta_aggregator` ∈ {`mean`,`max`,`sum`} (default `mean` unchanged → no `ESTIMATOR_VERSION` bump), `fork_score._delta_5{s,t,f}` dispatch via `_aggregate`, recorded in `ScoredFork.weights`, per-sub `HARD_REGRESSION_FLOOR` flags aggregator-independent; bench data behind keeping `mean` in `5f-threshold-calibration-2026-05-11.md` §5; 8+1 tests. #000012-revision / #000025 §10.14 follow-up | 2026-05-11 | — |

Headroom now down to 2 falsification-hard over-grounds (#000048 step 2.1 closed the 4 entity over-grounds; step 2.4 closed the 8 Formulate mis-segments → that pack 12/12; step 2.2 attempted + reverted — the last 2 recombination fixtures need an attribution-aware verifier, now tracked as **#000049**, and stand as documented residue). `make bench-5f-falsification-hard` / `bench-5f-formulate-hard` / `bench-fork-baseline-hard`; 7+ tests. #000025 §10.14 follow-up; #000047 closed; #000048 closed | 2026-05-11 | — |
