The new regression script relies on gen_random_uuid() but does not create the required pgcrypto extension in the disposable Postgres cluster, causing the script to fail on a fresh instance.

Pull request overview
Reduces authenticated cast-vote read amplification by moving revote/cross-area enforcement into a single trigger-guarded insert path, reusing already-loaded signing context for audit, and trimming unnecessary payloads/reads across backend and portal.
Changes:
- Centralizes revote-limit + cross-area exclusivity enforcement in a Postgres trigger under a per-voter advisory lock; updates Rust error mapping to preserve trigger public codes.
- Removes post-commit Keycloak/DB re-reads for audit by reusing the verified JWT username and an already-loaded system signing key; adds per-phase timing logs.
- Adds reproducible Postgres regression/validation tooling (migration test script + concurrent covering-index replacement script) and trims unused election EML from the portal query/types.

Verified against the configured PostgreSQL 18 devenv and the disposable-cluster test: gen_random_uuid() is built into PostgreSQL and does not require pgcrypto here. The test passes on a fresh cluster without that extension. No extension dependency added. Reference: https://www.postgresql.org/docs/18/functions-uuid.html

There are a couple of correctness/reliability issues (non-atomic run directory claiming in load::prepare, and missing HTTP status handling in import_voters) that should be fixed before merge.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Review details

Previously missed (1) — in code that hasn't changed since the last review.
packages/step-cli/src/commands/import_voters.rs:87
import_votersparses the response body as JSON without checkingresponse.status(). For non-2xx responses (e.g. 401/403/5xx), this will likely fail with a JSON parse error and hide the real HTTP status/body. Align error handling with other step-cli commands by checking status and returning the response text on failure.

overlay by disabling statement logging and changing log_file_mode from 0644 to
0600; ensure diagnostic logs containing E2E SQL and voter fields are not broadly
readable or unredacted.
In `@devenv.nix`:
- Line 120: Add ps.pyyaml to the package set used by the python3.withPackages
environment that runs the load-test entry points, alongside the existing
python3Packages.pyyaml dependency. Ensure load_test_common.load_config() can
import yaml without ModuleNotFoundError.
In `@packages/step-cli/scripts/load_test_common.py`:
- Around line 151-152: Update run_step to check proc.returncode before
returning, raising StepCliError whenever step-cli exits with a nonzero status
while preserving the existing Error! output check.
In `@packages/step-cli/scripts/run_telephone_load_test.py`:
- Line 314: Update the input-file selection in the rendering/execution flow
around tenant_out_dir and total_calls so only files rendered during the current
invocation are executed. Track each newly rendered path during the rendering
loop, or clear the inputs directory before rendering, and ensure total_calls
reflects that same current workload.
In `@packages/step-cli/src/commands/create_tenant.rs`:
- Around line 41-43: Update each command’s run() method to return Result and
propagate creation, registration, deletion, download, export, upload, and
key-ceremony status errors instead of only printing them. Update main to handle
these command results using the existing MainCommand::Load error-handling
pattern, preserving error output while producing a non-zero exit status; ensure
get_key_ceremony_status returns both not-found and request failures. Add a
command-level regression test covering a GraphQL or HTTP failure. Affected
sites: packages/step-cli/src/commands/create_tenant.rs:41-43,
create_trustee.rs:41-43, delete_tenant.rs:41-43, download_document.rs:31-33,
export_tenant_config.rs:41-43, get_key_ceremony_status.rs:31-36, and
upload_document.rs:27-29; each requires the corresponding error to be returned.
- Around line 78-80: Validate the endpoint URL scheme centrally when creating or

behavior in render_cohort so its table includes labels absent from the first
sample while preserving its existing conditional lookup.
In `@packages/voting-load/capture.py`:

packages/step-cli/src/load/mod.rs at lines 89-90 to the same 1.96.0 image.
In `@packages/voting-load/proxy.py`:
- Line 85: Update the diagnostic proxy startup around ThreadingHTTPServer to
bind to 127.0.0.1 by default instead of 0.0.0.0, while allowing wider binding
only through an explicit operator-configured choice.
In `@packages/voting-load/replay_profile.py`:
- Around line 76-78: Update the GraphQL replay validation around the iterator
consumed by the non-auth POST pairing to assert that no recorded requests remain
after all HAR operations are processed. Reject any surplus operation, including
unmatched mutations, instead of silently dropping it, and extend
test_new_mutations_and_unbound_publications_fail_closed with a surplus-operation

In `@packages/step-cli/src/utils/read_config.rs`:
- Around line 44-45: Replace the direct fs::write calls in write_config and
commands/configure.rs with one shared private atomic writer for
configuration.json. Have the writer create the temporary file with 0o600
permissions, write and sync the complete contents, then rename it into place;
update both paths to use it.
In `@packages/step-cli/src/utils/trustees/get_ceremony_status.rs`:
- Around line 30-37: Update get_keys_ceremony_status to distinguish an absent
sequent_backend_keys_ceremony_by_pk record from an existing ceremony whose
execution_status is None, using separate result states rather than collapsing
both to Ok(None). Update the command’s handling of that result so only the
absent ceremony reports “Keys ceremony not found,” while an existing ceremony
with no status receives a distinct message.
In `@packages/voting-load/Dockerfile.dockerignore`:
- Around line 3-14: Align packages/voting-load/Dockerfile.dockerignore with the
Dockerfile and image.rs inputs: replace the incorrect runner.spec.ts allowlist
with scale.spec.ts and include all required worker and query files used by COPY.
If directory-context builds are unsupported, remove the ignore file instead.
In `@packages/voting-load/test_capture.py`:
- Around line 109-111: Update the port allocation and PostgreSQL startup flow
around the socket binding and pg_ctl invocation to eliminate the
time-of-check/use race: either retry selection when startup fails or start
PostgreSQL with port 0 and read the assigned port from postmaster.pid. Preserve
the existing successful startup and subprocess error behavior.

🟡 Changes recommended
There are confirmed correctness/reliability issues in new load-engine parsing (k6 replay) and in multiple CLI task-polling loops that can fail when access tokens expire (since polling does not refresh tokens).
Once you've addressed the issues Copilot identified, you can request another Copilot review.

The minor findings are addressed in main 843151a and v10 5e8d1ec: PostgreSQL fixtures use a private Unix socket (no TCP port allocation race); telephone concurrency is validated and documented defaults are applied; long tenant/export/import polling refreshes authentication; missing ceremony status is distinguished from a missing ceremony; the stale Docker ignore file is removed; both configuration writers share a private atomic credential writer; build-time asset discovery propagates errors; Docker and indexed-worker failures include actionable context. The ID-token check and sparse capture chart handling are also fixed. Validation: native load tests pass (25, with the million-metric benchmark intentionally ignored), independent import-option parser cases pass, GraphQL partial-error cases pass, the real process-boundary HTTP 503 regression passes, and all 16 diagnostic Python tests pass. The report/guide use only actual 100-voter Chromium and 100-voter k6 runs; all 200 receipts were independently matched against PostgreSQL. No larger voting run is planned. For the optional API redesign suggestions, retaining the existing validated YAML strings, GraphQL boolean command options, task-status API, and document wrappers keeps this patch focused and compatible. Unknown YAML modes/executors already fail validation. The documented kubectl cleanup command covers retained resources, so no additional cleanup command or follow-up issue is needed. HTTP/local PostgreSQL support is deliberate for the required isolated synthetic devcontainer target; remote transport guidance now explicitly specifies HTTPS and TLS. |

🟡 Changes recommended
import-voters currently cannot propagate failures to a nonzero exit status (breaking automation), and devenv.nix includes a redundant Python dependency entry.

🔵 Needs a closer look
There are confirmed robustness/error-reporting issues (e.g., empty-HAR handling and misleading config write errors) that should be addressed before merging.

Previously missed (2) — in code that hasn't changed since the last review.
packages/voting-load/resources.py:92
extract()setsstarttoNonewhen the HAR has no entries, but later always does(timestamp - start), which will raise aTypeError. This can surface as a secondary crash when capture tooling produces an empty/partial HAR; returning an empty profile (or raising a clearer error) avoids hiding the root cause.
packages/step-cli/src/utils/read_config.rs:58write_config()usescrate::load::files::create()to create the temporary config file. That helper is tailored for load-run ownership and adds a run-specific error context ("use a fresh run...") that would be misleading for configuration writes, and it unnecessarily couples config I/O to the load module. Using a localOpenOptionscall keeps errors accurate and the module boundary cleaner.

The remaining targeted follow-ups are also in both stacks: main f31b2c7 and v10 4816562 share one Engine definition between coordinator and standalone worker; import response/polling tests cover success, partial GraphQL errors, empty data, failure and timeout; voter-import failures now propagate through the CLI dispatcher; token polling refreshes authentication; OAuth fields preserve bare flags and correctly decode plus signs and embedded equals. The standalone worker passes cargo check --locked. Main and v10 native load tests pass (25 each, large synthetic-metric benchmark ignored), import-state tests pass, and both process-boundary regressions pass. Credential creation/replacement was also verified with mode 0600 and no temporary-file residue. No further voting load was run after the two audited 100-voter examples. |

Run voting load tests through
step-cli load: native Rust election provisioning, streamed shared-hash census and encrypted ballots, finite local/Docker/Kubernetes workers, and disk-backed aggregation with p50/p99 and cast-throughput goals. k6 needs no browser preparation; Chromium exercises the full portal.The CLI runtime is Rust. JavaScript implements the k6/Chromium engine adapters. Standalone telephone setup scripts and optional developer capture/SQL diagnostics remain Python; they are not invoked by
step-cli load.Validation: native unit and command-failure tests; 100-voter k6 and 100-voter Chromium local runs, with all 200 receipts matched against PostgreSQL; local and Docker worker smoke tests. The guide includes the measured results and report screenshot. Kubernetes manifests are tested; a live cluster run is not yet verified.
