Description of the Solution

Implement the remaining ER-BSM-003 log observability work: write-time credential redaction in the playbook watcher, CI console log preview with CLI templates, and comprehensive test automation. This ensures logs are redacted before disk writes and provides operators with actionable log previews in GitLab pipelines.

Changes

Core Logs (src/build_stream/app/core/logs/redaction.py)

  • Add StreamRedactionState and redact_stream_line() for line-by-line streaming redaction
  • Support multi-line PEM key block detection across streaming boundaries

Playbook Watcher (src/build_stream/app/playbook-watcher/playbook_watcher_service.py)

  • Remove ANSIBLE_LOG_PATH from Ansible subprocess environment
  • Capture merged stdout/stderr via subprocess.Popen with reader thread
  • Apply Tier-1 redaction line-by-line before disk writes
  • Add timeout drain and fail-closed line suppression
  • Apply same redaction to validate/molecule output paths

CI Templates (src/build_stream/roles/hosted_gitlab/files/)

  • Add default.after_script to .gitlab-ci-build.yml, .gitlab-ci-cadence.yml, .gitlab-ci-deploy-child-template.yml
  • Preview last N execution-log lines (BSM_LOG_TAIL_LINES, default 50) for Ansible-backed stages
  • Print authenticated curl templates with <TOKEN> placeholder (no credential echo)
  • Non-fatal API-unreachable handling and 404 graceful messages
  • GitLab stage → BSM stage mapping per pipeline type

Test Automation

  • Add test/build_stream/nft/unit/playbook_watcher/test_write_time_redaction.py (8 real-subprocess tests)
  • Add test/build_stream/nft/unit/ci_console/test_after_script_log_preview.py (10 mock-server tests)
  • Update test/build_stream/nft/unit/core/logs/test_redaction.py (streaming redactor tests)
  • Update test/build_stream/nft/unit/playbook_watcher/test_stage_log_paths.py (Popen harness)

Documentation (src/build_stream/docs/contracts/INPUT_CONTRACT.md)

  • Document [log_query] configuration section in build_stream.ini
  • Document BSM_LOG_TAIL_LINES CI variable

Testing

  • Unit tests: 170 log-observability tests pass (redaction, watcher, CI console, API)
  • Lint: pylint scores 10.00 (redaction), 9.66 (watcher), 9.87 (tests) — all ≥8.0
  • Shell syntax: sh -n validated on all after_script blocks
  • YAML validation: All three CI templates parse correctly
  • Coverage: New code paths exercised by added tests (coverage tooling not available in sandbox)
  • Live-cluster FVT: TC-FVT-013–023 covered functionally by TestClient unit suite and mock-server tests; end-to-end verification in a live GitLab pipeline requires lab access (evidence gap recorded in story plans)

Backward Compatibility

  • No breaking changes
  • Write-time redaction is additive and defense-in-depth (logs were already redacted at response-time)
  • CI console preview is additive and reads existing per-job logs; no operator reconfiguration required
  • BSM_LOG_TAIL_LINES defaults to 50 if not set
  • Self-hosted and external GitLab modes share the same templates (AC-008 parity)

* feat(build_stream): add log query API with response-time redaction

Implements a read-only log query API for Build Stream that allows
authenticated clients to retrieve stage log content with response-time
redaction of sensitive data. The API enforces job ownership, path
traversal protection, rate limiting, and concurrency limits. Existing
job detail endpoint is extended with log metadata fields.

* revert(test): remove log_query FVT from this PR

FVT code has not been validated in a lab environment yet and will be
included in a follow-up PR.
…03-log-query-api-and-redaction)

Implement FR-3.1 write-time credential redaction. execute_playbook no longer
sets ANSIBLE_LOG_PATH; it captures merged stdout/stderr via subprocess.Popen,
redacts Tier 1 secrets line-by-line through the shared RedactionService, and
writes only sanitized output to disk. Handles non-UTF-8 (errors=replace),
multi-line PEM key blocks (streaming state), timeout drain, and fail-closed
line suppression. Applies the same redaction to the validate stage output.

Adds RedactionService.redact_stream_line + StreamRedactionState and unit tests
for the streaming redactor and the watcher capture path.

…M-003-ci-console-and-parity)

Add a self-contained default.after_script to the build, cadence, and deploy
child CI templates (AC-006/AC-007). On success and failure it previews the last
N execution-log lines (BSM_LOG_TAIL_LINES, default 50) for stages that ran an
Ansible playbook via GET /jobs/{id}/logs, and prints authenticated curl command
templates with a <TOKEN> placeholder (no credentials echoed). Runs in its own
shell, reads the freshest token from /tmp or the ACCESS_TOKEN dotenv var, maps
GitLab stage -> BSM stage per pipeline, and never changes the job exit status.
Self-hosted and external modes share these templates (AC-008 parity).

…SM-003-ci-console-and-parity)

Runnable verification of the default.after_script embedded in the build,
cadence, and deploy-child CI templates (AC-006/AC-007/AC-008). Drives the real
POSIX shell against a mock BSM log API: asserts the labelled tail preview,
custom BSM_LOG_TAIL_LINES, <TOKEN> CLI templates with no credential echo,
non-fatal API-unreachable handling, 404 graceful message, non-playbook-stage
skip, and cross-template parity.

…ig.yml (ER-BSM-003-log-query-api-and-redaction)

Expose log_tail_lines_default, log_tail_lines_max, max_log_response_bytes, log_query_rate_limit and log_query_max_concurrent as operator inputs in build_stream_config.yml (Section 5), with JSON schema, L2 validation and INPUT_CONTRACT docs. The log query API reads them at startup and falls back to build_stream.ini/defaults on invalid values.

…pt/omnia (ER-BSM-003-log-query-api-and-redaction)

Add tests for the log inputs (schema, validator, overlay, precedence). Isolate test_upload_use_case.py destinations in tmp_path; it previously overwrote the real orchestrator network_spec.yml and pxe_mapping_file.csv with test content.

…SM-003-ci-console-and-parity)

Add log_ci_preview_lines to build_stream_config.yml with schema and L2 validation (must not exceed log_tail_lines_max). The hosted_gitlab role pushes it to the GitLab project as BSM_LOG_TAIL_LINES on every run, and the CI templates no longer hardcode the value.

…ages (ER-BSM-003-log-query-api-and-redaction)

Unfiltered log queries list only create-local-repository, build-image, validate, restart and deploy. Filtering on parse-catalog or upload returns 404 explaining the stage has no execution log, and job detail reports has_log=false for them.

…SM-003-ci-console-and-parity)

Access tokens expire after 60 minutes, so after long playbook stages the after_script preview got 401. Mint a fresh token from CLIENT_ID/CLIENT_SECRET when the saved token is missing or rejected, in the build, cadence and deploy-child templates. Credentials are never printed and the hook never changes the job status.

…ter_script (ER-BSM-003)

- publish_stage_log: use copyfile + chmod 0644 + chcon instead of copy2 so the
  job log copy is not left as var_log_t/0600 (unreadable by the BSM container,
  which made the logs API return 404 / has_log=false).
- CI after_script: fall back to BSM_CLIENT_ID/BSM_CLIENT_SECRET when
  CLIENT_ID/CLIENT_SECRET are unset so a token can be minted.
- deploy child pipeline: export CLIENT_ID/CLIENT_SECRET from BSM_CLIENT_* so
  deploy/restart/validate jobs can fetch the execution log preview.

The deploy_openchami role resolved the latest release tag via the GitHub
API and built <tag>/openchami-0.2.0.rpm. When the latest tag moved to
v0.2.1 the asset name stayed openchami-0.2.0.rpm, so the URL returned
HTTP 404 and OpenCHAMI installation failed after all retries.

Use a fixed openchami_rpm_url (v0.2.0) and drop the release-metadata
lookup and the URL-derivation task.
