docs: close out RESEARCH_227 v4 after fail-closed OpenRouter fetch

[erikHtoo]

Summary

• Documents the first authenticated OpenRouter pricing-engine run and the fail-closed result.
• Adds the RESEARCH_227 v4 rate-card close-out memo.
• Establishes the archive convention for future validated snapshots and proposals.
• Documents daily refresh cadence, a 48-hour staleness threshold, and the fetch → compute workflow.

Live-run result

The authenticated fetch failed closed while resolving this dated OpenRouter identity:

z-ai/glm-5.2-20260616

• Exit status: 2
• Snapshot artifacts: none emitted
• Proposal: intentionally not run
• Rate-card and policy: unchanged

The engine did not guess an alias, invent a market price, emit a partial snapshot, or modify the live rate-card.

Verification

$env:PYTHONDONTWRITEBYTECODE='1'
python -m unittest -v scripts/tests/test_openrouter_pricing_engine.py
git diff --check

Result: 30 tests passed; whitespace check passed.

Follow-up

Repair or clarify the dated OpenRouter ranking identity versus catalog/endpoint identity contract, then rerun authenticated fetch. Only a successfully validated snapshot may be passed to compute.

Changes requested — failed-run hand-back, not RESEARCH_227 close-out

The fail-closed behavior was correct: no alias was guessed, no partial/hand-built snapshot was emitted, compute was not run, and neither the policy nor live rate card was modified. However, this PR is not ready to merge as a RESEARCH_227 operational close-out.

Why the run failed

The current OpenRouter catalog maps the dated canonical slug z-ai/glm-5.2-20260616 to both:

• z-ai/glm-5.2
• z-ai/glm-5.2:batch

The engine resolver only has a narrow rule for selecting a regular paid model over an explicit :free variant. It does not distinguish the regular model from :batch, so both remain candidates and the resolver correctly fails closed with:

catalog response cannot uniquely resolve ranked model 'z-ai/glm-5.2-20260616' to an endpoint model id

Please record this concrete regular-versus-:batch canonical-slug collision in the memo, rather than describing only a generic dated-model ambiguity, and identify the resolver/test repair as the follow-up blocker.

Why the original goals were not achieved

Because fetch emitted no validated snapshot:

• no first durable live snapshot was produced;
• compute correctly could not run, so no first live proposal exists;
• no trusted cheapest-active-endpoint inputs existed for priced-row movements;
• no validated top-50 policy-coverage diff existed;
• no demand-backed policy additions could be proposed.

The task explicitly permits a documented fail-closed hand-back, so this is a valid failure outcome. But it must be labelled a failed-run hand-back/blocker record, not an operational rate-card close-out. RESEARCH_227 remains blocked until the identity issue is repaired and a successful authenticated fetch → compute run produces the snapshot, proposal, priced-row movements, and candidate diff.

Required changes

1. Match the archive contract to actual engine filenames. docs/research/openrouter-snapshots/README.md:7-8 and docs/runbooks/openrouter-pricing-engine.md:34-35 document compact timestamps, no snapshot digest, and <digest8>. scripts/openrouter_pricing_engine.py:1208-1217 emits a hyphenated UTC timestamp plus a 16-character digest on both files. Document the exact executable naming grammar.

2. Commit a sanitized machine-generated failed-run receipt. The prose at RESEARCH_227_RATE_CARD_V4_MEMO.md:29-60 is not independently auditable and conflicts with the new runbook's instruction to persist stdout, stderr, and exit status. Add a dated, credential-redacted receipt containing the UTC run time/ranking window, engine commit SHA, exact command, exit status, sanitized stderr, output-directory listing, and evidence digest. Do not create a placeholder snapshot or archive partial demand data as trusted input.

3. Remove or sharply qualify conclusions from the unarchived “operator-provided top-50 table.” At memo lines 9, 15-21, and 101-131, the input is explicitly untrusted and has no durable provenance. It cannot support an exhaustive “only newcomer” or demand-gate conclusion. State that candidate-addition analysis is blocked pending a validated cohort; any Mistral work is illustrative offline research only.

4. Correct Mistral NeMo evidence. At memo lines 108-119, safetensors.total = 1,914,065,920 was misread as 1.91 GB. The linked MLX repository stores approximately 6.89 GB / 6.42 GiB. Also correct the OpenRouter identity from mistral/mistral-nemo to mistralai/mistral-nemo.

5. Source or qualify the Mistral TPS ranges. The 8-12 and 25-35 TPS values have no benchmark, calculation, or precise hardware basis. Cite the derivation or mark them explicitly as unverified estimates.

6. Cite the exact Nemotron governing agreement. The NVIDIA base-model card identifies the NVIDIA Nemotron Open Model License, not the generic NVIDIA Open Model License currently cited at memo lines 140-142. Cite the exact model card (preferably pinned) and its linked license. The commercial-permission conclusion may remain, but note the pre-existing policy evidence mismatch for owner follow-up rather than silently applying a policy change.

7. Describe the GLM blocker precisely. Record that z-ai/glm-5.2 and z-ai/glm-5.2:batch share canonical slug z-ai/glm-5.2-20260616, while the dated endpoint resolves to the regular identity. This makes the hand-back actionable.

8. Change close-out language. Update the title/status/conclusion so this lands as a failed-run hand-back and blocker record. Do not claim that the first live rate-card run or RESEARCH_227 payoff is closed until validated snapshot and proposal artifacts exist.

Verification

• Complete PR diff reviewed against base 0d524984feb3150548ea1ac3b38610ebb293b141.
• OpenRouter pricing-engine tests: 30/30 passed.
• make test: passed.
• git diff --check: passed.
• Required CI is green.
• No secrets, money-path writes, rate-card writes, policy writes, or apply mode were introduced.

Clarification to requested changes: complete the original task in this PR

The requested-changes review described how to preserve the current attempt if it remains a failed-run hand-back. That is not the desired final scope for this PR.

Please continue from the diagnosed blocker and complete the original RESEARCH_227 v4 task. The PR will be ready for re-review when all of the following are present:

1. Resolver repair, with tests. Resolve the z-ai/glm-5.2 versus z-ai/glm-5.2:batch shared-canonical-slug case using endpoint-confirmed identity—not a guessed alias or an unconditional rule that strips/ignores every :batch row. Accept the endpoint response ID only when it uniquely identifies a catalog candidate; otherwise continue to fail closed. Add tests for the successful regular/:batch case and unresolved/mismatched/malformed cases, while preserving existing :free and dated-alias behavior.

2. Successful authenticated live fetch. Rerun the documented top-50/30-day fetch after the repair. Commit the untouched, digest-stamped engine snapshot under the archive path together with sanitized command/run evidence. If authenticated access is no longer available, flag that prerequisite immediately so the owner can run fetch and provide the committed snapshot; do not fabricate or reconstruct it.

3. Successful compute. Run compute against exactly the fresh snapshot, current scripts/openrouter_pricing_policy.json, and current phase3-binary/catalog/autotune/rate-card.json. Commit the untouched proposal next to the snapshot. Do not apply it and do not edit the live rate card.

4. Completed V4 memo. Replace the failed-run-only conclusions with the actual priced-row movements for all four policy models, the structured proposal interpretation, the validated top-50 versus policy coverage diff, realistic candidate additions in policy-row shape with verified serving path/license/profile evidence, the four exact license confirmations, and data-quality notes. Correct the Mistral and Nemotron evidence issues identified in the review.

5. Accurate archive/runbook contract. Document the exact filenames emitted by the engine, the cadence/staleness rule, fetch→compute gating, and durable evidence layout.

The current failed run should remain documented as useful historical evidence, but a failed-run record alone does not close RESEARCH_227 v4. The legitimate close-out condition is:

resolver fix + successful authenticated fetch + committed snapshot + successful compute + committed proposal + completed movement/candidate memo.

Please keep the PR in changes-requested state until that end-to-end result is available for review.

[erikHtoo]

Addressed the requested end-to-end close-out:

• Added endpoint-confirmed resolver handling for the z-ai/glm-5.2 / z-ai/glm-5.2:batch canonical-slug collision, with success, mismatch, and malformed-response tests.
• Completed an authenticated top-50 / 30-day fetch and committed the untouched digest-stamped snapshot plus sanitized fetch receipt.
• Computed and committed the proposal from that exact snapshot, current policy, and current rate-card reference, plus sanitized compute receipt.
• Replaced the failed-run-only memo with the actual proposal interpretation, coverage diff, license corrections, candidate screening, and data-quality notes.
• Updated archive/runbook naming, evidence, staleness, fetch-to-compute gating, and resolver documentation.

Verification: 33 Python tests passed; git diff --check passed; receipt digests verified; no rate-card or policy changes were made.
