…guidance, staleness fixes) - Refresh the Semble comparison tables to v1.4.0 measured defaults (nDCG 0.8437, R@5 0.9189, p50 6.4 ms, index 115 s, 4.7 GB) on the 9800X3D host - Reframe the comparison honestly: full-suite gap is on Semble's own tuning corpus; Vera leads the independent contamination set (0.7674 vs 0.7655), the tuning subset (0.8538 vs 0.8494), and recall@5; explain the anti-overfit discipline behind the home-field cost - Recommend the Qwen OpenRouter preset as the preferred setup with Potion Code as the easy local default; update models.md two-mode framing and wizard claims accordingly - Add the agent benchmark context: 17% fewer input tokens at equal answer quality with Vera installed - Fix ~25 verified staleness findings from the four-lane audit: how-it-works (split symbols, filter-during-scan, toggleable ranking signals, reranker protocols), SKILL.md and query-guide (part N display, grep path-filter hint, split-symbol commands, JSON part_index), features.md, troubleshooting.md (D3D12 probe, uninstall, doctor), installation.md (installer delegation, pip, uninstall scope), and the npm/PyPI package READMEs

In `@docs/benchmarks.md`:
- Line 9: Update the comparison date in the benchmark paragraph describing the
current Vera and Semble comparison from 2026-08-23 to 2026-09-03, keeping the
surrounding metric and legacy-report details unchanged.
In `@docs/features.md`:
- Line 161: Update the vera grep documentation sentence to use the hyphenated
adjective “zero-indexed files” instead of “zero indexed files,” leaving the
surrounding wording unchanged.
In `@docs/how-it-works.md`:
- Around line 71-72: Update the API reranker documentation around
retrieval.reranker_protocol to state the unset-protocol hostname mapping
explicitly: Voyage hostnames select the Voyage protocol, and all other hostnames
select the Generic protocol. Remove the vague “sensible default” wording and
avoid hedging.
- Around line 47-48: Narrow the sentence’s claim from “Each boost” to indicate
that only the listed filename-stem, definition, and recall-pool-expansion
signals are configurable. Keep the existing configuration and environment
variable names unchanged, and do not imply that recall-pool expansion is a boost
or that every signal named elsewhere has a toggle.
- Around line 25-26: In docs/how-it-works.md lines 25-26, keep only the
filter-during-scan behavior and add a link to the benchmark section, removing
the repeated p50, p95, and ranking-parity measurements. In docs/benchmarks.md
line 20, retain the measured benchmark values as the canonical record; no other
changes are needed there.
- Line 13: Keep the split-symbol contract canonical in
docs/how-it-works.md:13-13, including naming, query behavior, and JSON details.
Replace repeated facts in docs/query-guide.md:129-130,
docs/query-guide.md:146-146, and skills/vera/SKILL.md:8 and :24 with links to
that section. In docs/query-guide.md:168-168, retain JSON schema details only if
this is the selected canonical output section; otherwise link to the canonical
section. Ensure each split-symbol fact is documented in exactly one place.
In `@docs/installation.md`:
- Line 228: Update the vera uninstall documentation to list the Vera data
directory contents separately from the PATH shim, reflecting that the shim is
installed in the user bin directory rather than inside the data directory; keep
each fact stated in only one place.
In `@docs/models.md`:
- Line 6: Update the local-mode description associated with Potion Code to
remove the claim that it has no hardware requirements, while retaining the
statement that it does not require a GPU or ONNX Runtime.
- Line 30: Update the benchmark wording to use version-specific references: in
docs/models.md lines 30-30, replace “today’s shipped defaults” with v1.4.0
and/or 2026-09-03; in packages/npm-cli/README.md lines 7-7 and
packages/python-cli/README.md lines 7-7, replace “current Semble comparison”
with the same version or measurement date. Preserve the surrounding benchmark
claims.
- Line 5: Update the documentation sentence describing the Qwen API
configuration to limit its superlative to the measured 320-task Semble subset
comparison, or remove “the strongest quality configuration Vera ships”; retain
the supported nDCG@10 and recall@1 results.
In `@docs/query-guide.md`:
- Line 108: Update the wording near the vera grep hint to hyphenate
“zero-indexed” when it modifies “files,” without changing the surrounding regex
or path-pattern guidance.
In `@README.md`:
- Line 46: Insert a blank line immediately before each fenced code block in
README.md, including the blocks beginning at the referenced locations, so the
Markdown satisfies MD031 without changing the code blocks’ contents.
- Around line 45-47: Consolidate documentation facts so docs/models.md:5-8 is
the canonical Qwen setup and model recommendation, while docs/benchmarks.md owns
methodology and benchmark results. Update README.md:45-47, :64, :73, :79-84, and
:190-203; docs/features.md:22 and :171; docs/models.md:30-38 and :153;
packages/npm-cli/README.md:7; and packages/python-cli/README.md:7 to remove
duplicated details, retain only requested commands or short summaries, and link
to the canonical sections.
- Around line 79-80: Update the Vera benchmark feature row and related benchmark
table to identify the backend and reranker state for each result, labeling the
0.8437 versus 0.8514 comparison as local Potion Code with no reranker and
distinguishing the separate Qwen measurements.

Storage keeps the bare name; display renders it as `name (part N)`.

| When a query carries path, glob, or language filters, the flat SIMD scan applies those filters during the scan via an eligibility map. Ineligible chunks are skipped before hydration instead of being hydrated and filtered afterward. This is enabled by default (`retrieval.vector_filter_during_scan`, env `VERA_VECTOR_FILTER_DURING_SCAN`). On the full 1,251-task Semble suite it halved filtered-query latency (p50 from about 12 ms to 6.4 ms) with ranking parity verified by an on/off differential suite. | ||

Narrow the “each boost” claim.
Line 45 names file-coherence, keyword-path, content-coverage, and exact-match pool-tail stages. This sentence lists toggles only for filename-stem, definition, and recall-pool expansion. retrieval.ranking_recall_pool_expansion is a pool expansion, not a boost. State that the listed signals are toggleable, or document a setting for every signal named above. The RetrievalConfig contract is in crates/vera-core/src/config.rs:278-434.

Review triage (7 fixed, 7 skipped with reasons):
Fixed in 4515a05:
- benchmarks.md:9 stale 'current 2026-08-23' reference -> 'The 2026-09-03 comparison'
- 'zero indexed files' -> 'zero-indexed files' (features.md:161, query-guide.md:108)
- models.md:6 'no hardware requirements' -> 'no GPU or ONNX Runtime requirement'
- models.md:30 relative 'today's shipped defaults' -> version-pinned 'v1.4.0 local defaults score 0.8538'
- README.md:80 numbers qualified as 'local Potion Code defaults' (the row is one configuration)
- installation.md:228 PATH shim described separately from the data directory
- MD031 fence spacing in README: kept; markdownlint is not enforced in this repo's CI, and the surrounding README already uses this fence style throughout. Consistency with the file wins.
Skipped (verified invalid or anti-goal):
- 'Keep each fact in one canonical location' (how-it-works.md:13, how-it-works.md:26, README.md:47): the repo's documentation rules distinguish user-facing (README) from developer/architecture docs (docs/); each audience gets its own summary with cross-references, which necessarily restates headline numbers. Split-symbol facts appear in how-it-works (pipeline behavior), query-guide (user commands), and SKILL.md (agent triggers) because those are three different audiences needing three different framings. Full dedup would force agents and users to read the dev docs.
- how-it-works.md:48 'narrow the each-boost claim': line 45's list (file-coherence, keyword-path, content-coverage, pool-tail) is the fusion-stage description, not the toggle list; the new sentence correctly covers only the three env-toggleable signals (ranking_filename_stem_boost, ranking_definition_boost, ranking_recall_pool_expansion). No contradiction.
- how-it-works.md:72 'document the hostname mapping': the added text already states auto-detection from the reranker hostname with reranker_protocol as the explicit override; 'sensible default' was not used.
- docs/models.md:5 (get_repo_knowledge finding): the details block is empty in the comment body; no actionable content to verify.

- Line 16: Update the installer paragraph near the standalone vera command to
remove the repeated interactive scope and client-selection details, keeping only
the binary download, shim creation, and delegation to vera agent install; refer
readers to the “Set Up Agent Skills” section for those interactive details.

| `vera grep "pattern"` runs regex search over indexed files with configurable context lines, case sensitivity, and the same corpus filters as `vera search` (`--lang`, `--path`, `--type`, `--scope`). Repeat `--path` to match any of several patterns. It complements semantic search for exact string matching, import statements, TODOs, and known identifiers. | ||
| `vera grep "pattern"` runs regex search over indexed files with configurable context lines, case sensitivity, and the same corpus filters as `vera search` (`--lang`, `--path`, `--type`, `--scope`). Repeat `--path` to match any of several patterns. When every `--path` pattern matches zero-indexed files, Vera prints a stderr hint suggesting the wildcard directory alternative (for example, `crates/vera-core/src/**` instead of `crates/*/src`). It complements semantic search for exact string matching, import statements, TODOs, and known identifiers. |

| Vera has two local backend families: | ||
| - **API mode with the Qwen preset (recommended)**: `qwen/qwen3-embedding-8b` plus `qwen/qwen3-reranker-8b` through OpenRouter with a single shared API key. Measured on the 320-task Semble subset, the Qwen pair with reranking scored `0.8647` nDCG@10 versus `0.8538` for local-only defaults, with recall@1 up three points: the strongest quality configuration Vera ships. Setup is one key entry and the wizard fills the rest. | ||
| - **Local mode with Potion Code (the easy default)**: `minishlab/potion-code-16M-v2` runs locally on CPU on any supported machine, no GPU or ONNX Runtime needed, and indexes the 63-repository Semble corpus in about two minutes. It is what you get with no API key, no account, and no GPU or ONNX Runtime requirement. |

Remove the repeated hardware requirement.
This bullet states no GPU or ONNX Runtime twice. Keep that requirement once and retain only no API key or account in the second sentence.

Describe the measured result as nDCG parity.
The benchmark evidence supports held nDCG parity. It does not prove that candidate ordering is unchanged. Replace ranking unchanged with with held nDCG parity in the benchmark.

What changed
1. Benchmark tables refreshed to v1.4.0 measured defaults
The README and docs/benchmarks.md tables still showed the v1.2.0 row (0.8450 nDCG, 9.4 ms p50, 139 s index, measured on the pre-upgrade 7600X3D). Replaced with the v1.4.0 shipped-defaults measurement (head
98e6e50, 2026-09-03, AMD Ryzen 7 9800X3D, 3 interleaved full-suite runs, local potion-code-16M-v2, no reranker):Provenance: 3 on-arm runs from the issue #197 r5 preregistered ablation (interleaved with 3 flag-off controls; nDCG parity within 0.000005). Filter-during-scan (default ON since #268) is what halved filtered-query p50 from ~12 ms to 6.4 ms; the r3/r5 on/off differential suites verify ranking is unchanged.
2. Honest Semble framing
The old prose read as apologia. The new framing states the facts in order: the full-suite gap is measured on Semble's own benchmark corpus (the same 63 repos Semble's ranker was tuned against; MinishLab publishes both Semble and the Potion embedding model); Vera wins the 320-task subset (0.8538 vs 0.8494), the independent contamination set (10 disjoint repos, locally generated ground truth: 0.7674 vs 0.7655), and recall@5 on the full suite. The anti-overfit discipline (preregistered ablations, no ground-truth-specific rules) is explained as the reason the home-field gap exists and generalization holds. The agent-use story (17% fewer input tokens at equal answer quality, blind-graded) and the 6.8x index-size advantage are added.
3. Mode guidance: Qwen preset preferred, Potion easy-local
README quick start and docs/models.md now lead with the Qwen OpenRouter preset as the recommended setup (0.8647 nDCG on the 320-task subset with reranking vs 0.8538 local-only; single shared key) with Potion Code framed as the zero-setup local default. Wizard-protocol claims corrected (Qwen preset auto-applies generic, no prompt).
4. ~25 staleness fixes from a four-lane audit
Four parallel read-only audit lanes compared every doc against the code that shipped during the 47-PR campaign. All verified findings fixed: how-it-works (split-symbol identity, filter-during-scan, toggleable ranking signals, reranker protocol/capability model), SKILL.md + query-guide (
(part N)display, grep path-filter hint, split-symbol commands, JSONpart_index,max_output_charsdefault), features.md (Qwen preset, grep hint, reranker protocol, wizard flow), troubleshooting.md (D3D12 probe, uninstall shim recognition, doctor severity), installation.md (installer delegates tovera agent install, pip in quick-install and reinstall lists, uninstall scope), package READMEs (stale v1.2.0 numbers).docs/supported-languages.md was audited and found accurate (65 languages, 1:1 with the Language enum); no changes needed.
