+# Relevance calibration preparation
+
+The existing frozen mixed diagnostic returned candidates for all ten requests
+without a relevant source. That observation identifies an abstention problem;
+it does not justify choosing a cosine cutoff on those same queries.
+
+The new [text/code diagnostic](../fixtures/relevance-v2/README.md) separates
+calibration and held-out topic families and repositories before inference.
+Its 14 files support 48 English/German queries: 32 positive requests and 16
+requests for absent artifacts or implementations. Both translations of an
+intent stay in the same split. A broadly related neighbour may be useful for
+an exploratory topic query, so these absence labels require concrete artifacts.
+
+The source inventory and blinded review have been completed. Independent AI
+review agreed with all expected file sets; the final labels are frozen in
+`fixture.json` with hashes and a UTC timestamp in `fixture.lock.json`.
+No retrieval run, threshold selection or ranking change has occurred. Agent
+agreement will not be described as human review.
+
+The first independent agent review detected Windows-1252 mojibake in the
+authored German requests and ambiguity in the wildcard-comparator request.
+Before inference or freezing, German request strings were restored to Unicode
+and the comparator request clarified to a lone `*` followed by another
+comparator, such as `*, >=1.0.0`. Numeric partial versions such as `1.*` are
+outside that rejection claim. The original blinded input and per-query changes
+are preserved in `fixtures/relevance-v2/review-history`; upstream source and
+licence bytes were unchanged. The corrected independent re-read agreed with
+all expected file sets. Before freezing, two further paired requests were made
+more precise: bounded pattern search requests its first match, and the museum
+request asks for operative loan terms rather than an executed agreement.
+Both the preceding input and report remain byte-exact in review history;
+independent re-reading confirmed those four wording changes.
+
+An absent label means the requested artifact or implementation is missing.
+It does not mean no related file exists or that related files must never be
+shown as suggestions. Any future abstention policy must distinguish that
+semantics explicitly when it reports results.
+
+After freezing, use calibration only to propose an explicit relevance policy;
+**Keep held-out queries unevaluated until that policy and its parameters are fixed.**
+report positive recall alongside absent-query behaviour. Preserve raw candidates,
+native and end-to-end timings, model/runtime hashes, task scope and any unsupported
+filters. Evaluate the held-out split once without selecting parameters from it.
+If labels need correction after model output, create a new version and explain
+why instead of altering this diagnostic silently.
+
+This small corpus does not close independent human relevance, media abstention,
+music discrimination, speech localisation or production-scale quality gates.

+# Text and code relevance diagnostic
+
+This frozen fixture contains 14 actual files and 48 English/German requests. It is a
+small, agent-authored diagnostic, not a human-labelled production quality gate.
+No inference has been performed against these labels.
+
+`inventory.json` records exact source bytes, upstream immutable commits and
+complete licence files. Twelve documents describe fictional organisations and
+procedures; no customer information is used. Two complete Rust files come from
+unrelated upstream projects. Local `.gitattributes` prevents Git newline
+conversion of source and licence files.
+
+Calibration uses bicycle warranty, bakery labels, apartment maintenance and
+aho-corasick. Held-out uses museum loans, irrigation, ferry operations and
+semver. Topic families and upstream repositories are disjoint. Each bilingual
+intent pair stays within one split. Positive requests include contrasting
+nearby procedures; absent requests require a specific missing artifact or
+implementation. A related topic alone cannot fulfil such a request.
+
+The independent agent reviewer should read only `blind-review-input.json` and
+its referenced source files, then return candidate file IDs, an empty set for
+an absent artifact, or an explicit ambiguity. Do not read `author-labels.json`
+until that review is saved. No vector, search ranking or threshold is available
+to either annotator. Disagreements must be resolved with written reasons before
+a final immutable label lock is created.
+
+The independent AI review is now saved and agreed with all expected file sets.
+`fixture.json` combines the reviewed queries and labels; `fixture.lock.json`
+records their hashes and the UTC freeze time before any inference. Review history
+preserves encoding repairs and wording clarifications before that freeze.
+**Do not evaluate held-out queries until a policy or threshold has been fixed
+using calibration only.** Do not adjust that policy from held-out results.
+
+No media is included: this corpus cannot calibrate music, images, video or
+spoken-passage abstention. Existing media benchmarks remain separate. A held-out
+split made by the same author is weaker than independent human annotation and
+larger real customer libraries.
+
+Run `python fixtures/relevance-v2/verify.py` for source integrity and split
+structure. That check proves consistency, not retrieval quality.
+Run `python fixtures/relevance-v2/test_verify.py` for isolated corruption,
+duplicate, split-leak and lock regressions, including verifier execution with
+Python optimization enabled.

+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   copyright license to reproduce, prepare Derivative Works of,

+   (except as stated in this section) patent license to make, have made,
+   use, offer to sell, sell, import, and otherwise transfer the Work,
+   where such license applies only to those patent claims licensable
+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+

+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and

+   (b) You must cause any modified files to carry prominent notices
+       stating that You changed the files; and
+
+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+# Moving-day meter record
+
+Residents of Rowan Court photograph the electricity meter on moving day. The photograph must show the reading and the meter identifier. Send it with the handover date to the property office within three days. The office uses the reading for the departing resident’s final bill.

+# Loan transit cover
+
+The Elm Museum loan agreement requires insurance during both outward and return transport of the ceramic bowl. The borrower supplies an insurance certificate naming the museum before collection. Coverage is for the agreed replacement value of 12000 euros.
