# Session Log - 2026-04-15 - 2026-Q1 quarterly maturity review

- **Last reviewed:** 2026-04-15
- **Review cadence:** ad-hoc (point-in-time)
- **Status:** complete

## What this session was

Standing 2026-Q1 quarterly maturity review for mql-enrichment-service. Driven by the validate skill against the current state of the instance. Participants: RevOps-AI eng team (4 engineers + lead), one Platform Engineering pair, Compliance Engineering observer.

Goals:

1. Run full audit; produce updated MATURITY-SCORECARD
2. Drain inbox pairs (`from-{{platform_team_name}}.md`, `from-sdr-team.md`)
3. Confirm primary metric (SDR-accepted-MQL rate) hold
4. Identify highest-leverage next move for Q2

## What was produced

| Artifact | Path | Status |
|----------|------|--------|
| Updated maturity scorecard | `MATURITY-SCORECARD.md` | modified - audit refreshed against current state |
| Updated OPERATING-MODEL "highest-leverage next move" | `OPERATING-MODEL.md` | modified - resolved Q1 open items; named the L4 mirror drift as Q2 priority |
| BACKLOG entry for mql-router p99 latency | `BACKLOG.md` | new entry |
| BACKLOG entry for tier-3 placeholder cosmetic | `BACKLOG.md` | new entry |
| Drained inbox `from-{{platform_team_name}}.md` | `inbox/from-{{platform_team_name}}.md` | 4 entries drained, 2 acknowledged, 2 actioned |
| Drained inbox `from-sdr-team.md` | `inbox/from-sdr-team.md` | 7 entries drained; 5 actioned, 2 escalated |

## Decisions made

- **Decision:** Tightened `latency-target-miss` alert threshold for mql-router from "p99 > 1.5s sustained 30 min" to "p99 > 1.2s sustained 15 min." Routine alert hygiene; not ADR-worthy (low reversibility risk; documented in `cross-platform/alert-routing.yaml` change history).
- **Decision:** Retired P2 alert `tier-3-low-utilization`; had not fired in 6 months and the underlying signal is now captured in monitoring panels directly. Not ADR-worthy; routine hygiene.

No ADR-worthy decisions.

## Findings

- **Finding:** L4 mirror sync 14 days behind source. Two prompt-library updates and one eval-harness update pending pull.
  - **Why it matters:** Quarterly eval refresh in 2026-Q2 will run against drifted harness; results not comparable to Q1 baseline
  - **Next move:** RevOps-AI eng lead schedules sync with Platform Engineering pair; closes-by 2026-05-05
  - **Recorded where:** OPERATING-MODEL.md "Single highest-leverage next move"; BACKLOG entry created

- **Finding:** mql-router p99 latency (1.8s) above target (1.0s); affects ~3% of MQLs (LLM-judge tiebreak case).
  - **Why it matters:** Cosmetic-grade impact today (downstream still functions; mql-router queue does not back up); could become user-facing if tiebreak frequency increases
  - **Next move:** Pre-warm tiebreak prompt with cached embeddings of recent assignments; closes-by 2026-06-01
  - **Recorded where:** BACKLOG.md entry; mql-router dossier "Open ADRs and findings"

## State changes

- **Layer maturity changes:** L4 platform kit moved from `mature` to `partial` (mirror status `live` -> `declared-but-inactive` for prompt-library and eval-harness components; the 14-day drift triggered the demotion). Will return to `mature` once sync completes by 2026-05-05.
- **Relationship status changes:** none (all live relationships still live)
- **Pinned-version changes:** no model bump this quarter; eval-data snapshot refreshed (2026-Q1 dataset versioned `revops-mql-eval-2026-Q1@{hash}`)

## Concurrent-actor notes

Single-thread session. RevOps-AI eng team coordinated through one shared screen-share; Platform Engineering pair joined for the kit-mirror discussion specifically; Compliance Engineering observer asked clarifying questions during the L2 / L7 sections but did not edit artifacts.

No concurrent-write conflicts.

## Handoff posture

What the next session needs to know:

- **Where things stand:** Q1 review complete; primary metric on target (44.1% rolling 30-day vs. 42% target; SDR-accepted rate holding); one open priority item (L4 mirror drift) and one non-blocking polish item (mql-router p99)
- **Where to start:** L4 mirror sync next; RevOps-AI eng lead has the action
- **Pending blockers:** Platform Engineering pair availability (will be scheduled during their next sprint)

Kickoff: no update needed; OPERATING-MODEL captures the next move.

## Failure modes encountered

- **Caught: overclaimed completeness.** Initial scorecard draft marked L4 as `mature` despite the 14-day drift; the validate skill flagged this against the four-step scale (drifted mirror is not `mature`; should be `partial` until sync completes). Standard reinforced: trigger from BOOTSTRAP-BRIEF Section V "When asked to assess maturity" applied; downgrade was made.
- **Caught: untested relationships.** Initial scorecard marked the prompt-library mirror as `live`; correct status given the drift is `declared-but-inactive` (the relationship has been declared but is no longer producing the expected up-to-date effect). Demoted accordingly.

## Session metadata

- **Effort:** ~120 minutes (full audit + drain + scorecard refresh)
- **Format:** Single-thread; one mid-session pair-with-Platform-Engineering for kit-mirror discussion
- **Operators:** RevOps-AI eng team (5 people), Platform Engineering pair (2 people), Compliance Engineering observer (1 person)
- **Tools used:** validate skill (ran full pass), architect-audit skill (referenced for layer scoping), architect-lifecycle skill (refreshed staleness flags)
