Description

Release prep for 0.11: two features and the minor version bump.

--output otel (#738, phase 1)

otel is now a general output format for stackql exec and stackql shell: the result set is emitted as OpenTelemetry log records in OTLP/JSON, one LogsData per row, streamed and flushed like jsonl, plus one completion record per statement. Designed for "cloud config snapshot as telemetry": ship an inventory query's rows on a schedule and let an OTLP backend answer latest-state, drift and entitlement-history questions.

Record shape, per the issue:

• Every record of a statement carries the same timeUnixNano (the statement start time, the snapshot instant), the same stackql.snapshot.id and the same spanId; one traceId per invocation, honouring TRACEPARENT from the environment.
• Body is the full row as compact JSON. Attributes are each column under its own name (scalars typed, nested columns as JSON strings, nulls dropped), plus stackql.snapshot.id, stackql.query, stackql.query.hash, stackql.provider / stackql.service / stackql.resource (single-table SELECTs only), stackql.row.index and stackql.row.fingerprint (sha256: of the canonical row JSON).
• The completion record carries stackql.snapshot.complete=true, stackql.rows_returned and stackql.duration_ms, and is emitted for a zero-row statement too.
• Resource attributes: service.name (overridable via OTEL_SERVICE_NAME), service.version, cloud.provider / cloud.account.id / cloud.region / cloud.availability_zone derived from the statement's provider and WHERE equalities where possible, and OTEL_RESOURCE_ATTRIBUTES pairs.
• Failed statements produce an ERROR record with error.type / error.message under the record error presentation; the default stderr presentation is unchanged.
• Own instrumentation scope (internal/stackql/output, schema 1.0.0) pinned by a unit test, separate from the MCP audit scope.

Implementation reuses pkg/sink.NewOTelSink from #732. The only sink change exports the JSON-to-attribute mapping (OTelAttributesFromJSON) it already had, and decodes numbers via json.Number so large integers keep precision; the audit encoding is unchanged (its tests pass). The statement text and start time reach the writer through two new fields on internaldto.OutputContext, stamped in driver.ProcessQuery and carried by HandlerContext. google/uuid moves from indirect to direct in go.mod.

Phase 2 (OTLP/HTTP push exporter) and phase 3 (backend recipes) are separate PRs, as the issue lays out. The global-flags page in the docs repo needs otel added to the --output list.

SHOW CONTRIBUTORS (#320)

Hidden credits, per the issue: SHOW CONTRIBUTORS; returns a contributor column, contributions descending; SHOW EXTENDED CONTRIBUTORS; adds contributions. Works in exec, shell, srv and therefore the MCP server from one implementation, via the three touch points the issue names plus a new leaf package internal/stackql/contributors that go:embeds contributors.csv.

The vendored CSV was generated by the issue's query through stackql itself against the live GitHub API (17 rows). Two things differ from the issue text:

• The generation workflow (.github/workflows/contributors.yml, monthly + workflow_dispatch) calls stackql exec directly after setup-stackql rather than through stackql-exec. The stargazer list is 898 long and stackql-exec cannot pass --http.response.pageLimit=-1, so through the action the join silently caps at 600 stargazers and drops exactly the recent stargazers the feature is meant to reward. The query itself is verbatim from the issue plus a login tie-break so regenerations are deterministic.
• The row guard is <= 10, not <= 20: the real eligible count today is 17, so the issue's threshold would have refused the list on day one.

The denylist carries claude (a User-type AI agent account). PRs the workflow opens with the workflow token do not trigger CI; the workflow comment says to close and reopen. Not documented in stackql-docs.

Version

cicd/version.txt MinorVersion 10 to 11, so the next tag is v0.11.<build>.

Type of change

• Feature (non-breaking change to add functionality).

Evidence

Go:

• internal/stackql/output: six new tests pin the row and completion attribute schemas, typed/nested/null column handling, shared snapshot identity across records, resource attributes, the zero-row completion record, fingerprint stability and change detection, and the error record.
• internal/stackql/contributors: embed parses, descending order, founder on top, parse-once.
• pkg/sink and pkg/mcp_server/audit suites unchanged and green.
• Full go test --tags sqlite_stackql ./... and golangci-lint v2.5.0 clean locally; actionlint 1.6.23 clean on the new workflow.

End to end (WSL, local build 0.11.0, github flask mock): 8-row query yields 8 row records plus 1 completion; shared time, snapshot id and span; TRACEPARENT honoured; second statement gets a new snapshot id and span under the same trace; OTEL_RESOURCE_ATTRIBUTES land on the resource; fingerprints identical across two runs and distinct across rows; zero-row statement yields exactly one completion record with rows_returned=0. SHOW CONTRIBUTORS and SHOW EXTENDED CONTRIBUTORS verified in exec and shell; SHOW VERSION reports 0.11.x.

Robot (new scenarios, run locally via the fast path, all passing):

• stackql_mocked_from_cmd_line.robot: OTel Output Emits One Record Per Row Plus Completion (two runs, fingerprints compared) and OTel Output Zero Row Statement Emits Only Completion, through a new Should StackQL Exec OTel Snapshot keyword in StackQLInterfaces.py. The keyword takes the known attribute values as JSON (context verified on every record, rows in order, completion) with OTLP values decoded to native types, so the eight mock rows' login / contributions / stackql.row.index, the statement context and the completion counts are asserted exactly; dynamic values (ids, timestamps, fingerprints) are left unlisted. Verified it fails on a wrong value.
• stackql_mocked_from_cmd_line.robot: Preview Rows Are Emitted Throughout The Run As OTel Records, the sibling of the jsonl streaming scenario: 79 rows plus the completion record (80 lines) must grow on stdout while the query runs.
• stackql_from_cmd_line.robot: Show Contributors, Show Contributors Extended.
• mcp.robot: PG Server Show Contributors over the wire protocol (runs in CI with the suite's server setup).

Checklist:

• A full round of testing has been completed, and there are no test failures as a result of these changes.
• The changes are covered with functional and/or integration robot testing.
• The changes work on all supported platforms.
• Unit tests pass locally, as per the developer guide.
• Robot tests pass locally, as per the developer guide. (new scenarios via the fast path; full sweep left to CI)
• Linter passes locally, as per the developer guide.

Tech Debt

• stackql.query is the submitted input text; for a multi-statement input every statement's records carry the whole batch. Per-statement text would need the orchestrator's per-statement context to reach the response handler.
• stackql-exec cannot pass CLI flags, which is why the contributors workflow calls the binary directly. A flags input on the action would let it switch back.

Closes #320. Part of #738 (phase 1; phases 2 and 3 to follow).
