+# ADR 0034 — Analysis-run create loopback CLI
+
+**Decision status:** Accepted
+**Implementation maturity:** active-PR
+**Date:** 2026-08-31
+**Supersedes:** None; complements ADR 0018 for the operator-visible create client. Does not supersede ADR 0014 claim-promotion authority. ADR 0026–0033 remain on live GAP-003A engine-library, terminal-wire DTO, GET-by-id, lifecycle-POST, cancel-HTTP, scientific-acceptance CLI, collection-GET, collection-CLI, and cancel-CLI slices.
+
+## Context
+
+ADR 0018 accepts `POST /v1/analysis-runs` on the loopback listener, but operators still had to write raw HTTP/1.1 to submit a metric-free analysis run. Duplicating create HTTP, GET-by-id, lifecycle POST, cancel HTTP, the scientific-acceptance CLI (`tepp-analysis-run` on live #362), collection GET, collection CLI `list`, or cancel CLI would collide with live PRs.
+
+## Decision
+
+`tepp_api` extends the loopback-only `tepp-analysis-runs` CLI:
+
+- `create` POSTs `/v1/analysis-runs` with `--idempotency-key` and a typed `AnalysisRunRequest` stdin body.
+- Empty stdin is refused. The body's idempotency key must match the flag.
+- Stdout is metric-free `202 Accepted`: `run_id`, `run_state=accepted`, and `idempotency_key`.
+- `tepp.scientific_acceptance.v1`, RMSE, bias, coverage, SE-gate, report, and `terminal_result` never appear.
+- Non-loopback hosts, unpublished consumers, credential-shaped flags, collection pagination flags, cancel `--run-id`, unknown verbs, mismatched keys, and metric bodies fail closed.
+- Persistence, Compose recovery, and psychometric execution remain GAP-003B.
+
+## Alternatives considered
+
+1. **Keep raw HTTP as the only create path** — rejected because operators still guess framing after ADR 0018.
+2. **Add `create` onto the live scientific-acceptance CLI (#362)** — rejected because that head already owns create/running/terminal/status for the scientific-acceptance profile and is stacked on GET-by-id, not the collection/cancel operator binary.
+3. **Open a second `tepp-analysis-runs` binary beside collection CLI list (#371) and cancel CLI (#378)** — rejected because the operator-visible command is the same binary.
+4. **Persist created rows in PostgreSQL** — rejected as GAP-003B / live draft #287.
+5. **Loopback create CLI with the same metric-free gates as ADR 0018** — accepted.
+
+## Consequences
+
+- Operators can submit metric-free analysis runs on the same loopback listener that lists and cancels them without writing HTTP.
+- Accepted receipts cannot be mistaken for a succeeded scientific-acceptance result.
+- CLI success is not release evidence.
+
+## Failure and recovery
+
+Non-loopback hosts return authorization denied. Unknown verbs, metric keys, mismatched idempotency keys, unpublished consumers, credential flags, empty stdin, and collection/cancel flags fail closed. Conflicting idempotent bodies remain refused by ADR 0018. The in-memory registry is not durable.
+
+## Security, privacy, scientific-integrity, and governance impact
+
+- No credential headers cross the consumer boundary.
+- The CLI remains loopback-only and size-bounded.
+- Process exit 0 on an accepted receipt is not measurement evidence and is not an ADR 0014 claim.
+
+## Compatibility and migration
+
+Cancel HTTP, collection GET, collection CLI `list`, cancel CLI, create POST, temporal-context, and project-history paths are unchanged. The scientific-acceptance CLI binary name `tepp-analysis-run` remains owned by ADR 0030 / #362. Production adapters may replace loopback while preserving metric-free accepted receipts.
+
+## Verification
+
+Falsifiable evidence:
+
+- CLI create JSON has no RMSE/bias/coverage/SE-gate/scientific-acceptance keys and no `terminal_result`;
+- CLI create of a valid request is metric-free `accepted` and replay is idempotent;
+- another consumer cannot collide with the first consumer's idempotency key;
+- non-loopback host, credential flags, collection/cancel flags, metric stdin, empty stdin, and unknown verbs fail closed;
+- Clippy `-D warnings`, `tepp_api` tests, rustdoc, and exact-head review remain required.
+
+## Rollback and supersession
+
+Rollback removes the create verb from `tepp-analysis-runs`; collection `list`, cancel, and create HTTP remain valid. A superseding ADR is required to persist the registry, bind a public address, emit scientific-acceptance on create, or treat CLI success as an ADR 0014 claim.
+
+## Related authority
+

+- ADR 0032 owns `tepp-analysis-runs list`.

+# Analysis-run create CLI (doctoring)
+
+## Scope
+
+`tepp-analysis-runs create` is the operator-visible client of loopback
+`POST /v1/analysis-runs`. HTTP method, path, and header semantics follow
+current HTTP semantics (Fielding, Nottingham, & Reschke, 2022). Fail-closed
+refusal of non-loopback hosts, unpublished consumers, review/Copilot/GitHub
+credential flags, and scientific-authority promotion is repository contract
+authority (ADR 0034; ADR 0018; ADR 0011), not an RFC inference rule.
+
+CLI stdout is metric-free `AnalysisRunAccepted` JSON with `run_state=accepted`.
+The receipt carries `run_id`, `run_state`, and `idempotency_key` only.
+Process exit 0 is not a completed temporal model, calibrated score, theta
+estimate, uncertainty statement, or scientific claim.
+`tepp.scientific_acceptance.v1` never appears.

+(RFC 9110). IETF. https://doi.org/10.17487/RFC9110
+
+RFC 9110 §9.3.3 describes POST as a method for processing the enclosed
+representation according to the resource's own semantics. TEPP maps that
+processing onto a bounded, consumer-scoped create of a metric-free analysis
+run. The RFC does not define psychometric acceptance, RMSE, or claim
+promotion.
+
+### Internal contract evidence
