Lesson 166: Weekly SLA Snapshot Reconciliation Job and Signer Acknowledgment Routing (2026)

Direct answer: Lessons 164–165 aligned dashboards and footers—yet partner annex weekly totals can still drift from leadership rollups when jobs fail silently or signers never see a clean ack row. This lesson ships a scheduled reconciliation job, a signer-visible acknowledgment route tied to tuple revisions, and a red governance state when the job is skipped twice during overlapping Store and Quest submission pressure in 2026.

Why this matters now (2026)

Concurrent Steam page updates and Quest certification uploads compress the window where finance, ops, and legal all believe the same SLA numbers. A missed nightly export is survivable; a missed weekly reconciliation during that overlap is how partner annexes diverge from leadership tiles without anyone owning the variance.

Pair this lesson with the Unity preflight chapter Unity 6.6 LTS OpenXR Governance Weekly SLA Snapshot Reconciliation and Signer Acknowledgment Routing Preflight so editor-side telemetry hooks and ops job manifests stay aligned with signer routing tables.

Prerequisites

  • Lesson 164 metric dictionary IDs, UTC windows, epsilon gates, and executive readback projections
  • Lesson 165 footer_schema_semver and replay-parser contracts so reconciliation artifacts parse identically in replay lanes
  • A job runner (CI, warehouse scheduler, or orchestrator) that can call SQL or REST with audit logging

Outcome for this lesson

You will implement:

  • a weekly reconciliation job manifest listing leadership rollup query id, partner annex export id, tuple revision hash, and epsilon policy version
  • a diff artifact that stores per-metric_id deltas with pass or fail plus owner route on fail
  • a signer acknowledgment row that appears only when the job completes green twice in a row or after a documented manual override with audit id
  • a red governance flag when two consecutive scheduled windows produce no successful job row—forcing explicit human acknowledgment before publish continues

1) Define the reconciliation contract as narrowly as the metric dictionary

Reuse Lesson 164 vocabulary—do not invent parallel column semantics.

  • bind each compared aggregate to metric_id and tuple_revision_hash
  • freeze window_tz_policy = UTC identical to dashboard exports
  • attach epsilon_policy_version so epsilon changes are replayable

Success check: diffing job inputs shows the same start_inclusive / end_exclusive pair as leadership and partner manifests for that week.

2) Schedule the job with skip visibility, not silent failure

Configure the scheduler to emit:

  • job_run_id, scheduled_at, started_at, completed_at
  • skip_reason nullable—maintenance, credential rotation, manual pause
  • artifact_uri for the diff JSON or CSV stored immutably beside tuple archives

Success check: Grafana or equivalent shows a flat line of job completions; gaps longer than one week trigger paging before signer views update.

3) Route signer acknowledgment only on defensible states

Avoid training signers to click ack on amber.

  • Green ack eligible when job status is PASS and prior run was PASS or first-run bootstrap documented
  • Amber hold when job PASS follows a FAIL until owners attach remediation evidence ids
  • Red block when two consecutive skips or two consecutive FAIL without override packet

Success check: signer UI cannot emit ack without job_run_id foreign key populated.

4) Wire partner annex totals to the same diff engine as leadership

If partner annex totals arrive as PDF tables, require machine-readable sidecars—Lesson 165 parser contracts apply.

  • reject annex uploads whose footer_schema_semver is newer than reconciliation parser contract_max_semver
  • store annex ingest_hash beside leadership ingest_hash on the reconciliation row

Success check: replay can prove partner and leadership inputs both existed for the acked week.

5) Escalate red governance state into release train gates

When red triggers:

  • block dashboard publish pipelines that push leadership tiles to CDN or SharePoint
  • open signer-visible incident row referencing missed job_run_id windows
  • require executive readback addendum if numbers already reached partner comms

Success check: no Store or Quest-facing numeric comms ship while red flag is set without override annex.

Mini challenge

  1. Add a weekly schedule with synthetic failure injection—confirm pager fires on double skip.
  2. Map signer ack table to job_run_id; attempt UI ack without job—verify database constraint blocks it.
  3. Run partner annex with intentional 0.5% drift beyond epsilon—confirm amber path before green ack returns.

Pro tips

  • Keep reconciliation SQL or notebooks in the same repo as parser contracts so semver bumps ride together.
  • Publish a one-page FAQ for signers explaining amber versus red—reduces midnight Slack clarifications.
  • Pair weekly reconciliation with Lesson 162 buffer burn-down visibility so staffing excuses do not masquerade as metric drift.

Key takeaways

  • Weekly jobs beat heroic manual diffs when Store and Quest lanes overlap in 2026.
  • Signer acks must bind to job_run_id, not vibes.
  • Double-skip red state forces explicit human ownership before silent drift compounds.
  • Footer semver and parser ceilings from Lesson 165 keep annex ingestion compatible with the same diff engine leadership uses.

FAQ

Can reconciliation run daily instead?
Yes if load allows—tighten red rules accordingly so alert fatigue stays sane.

What if partners refuse machine-readable annexes?
Treat as governance defect; OCR pipelines are not replay-grade for certification evidence.

Do we reconcile revenue metrics here?
Keep scope to SLA operational metrics agreed in Lesson 164 dictionary—finance KPIs deserve their own job family.

Next lesson teaser

Continue with Lesson 167 - Synthetic Replay Diff Gate for Dashboard Column Variance Epsilon Policy (2026) to add CI or nightly synthetic replay against frozen CSV goldens, enforce column parity and epsilon numeric gates, and block merges when exporter or BI pipelines regress before weekly reconciliation runs.

Continuity:

Scheduled reconciliation turns paired dashboards from a momentary agreement into a weekly provable habit.
