Per-task complexity (Phase B): AZ-513 (3) + AZ-196 (2) + AZ-183 (3, reverted) + AZ-197 (3) = 11 points.

Security Audit (out-of-band, post-implementation)

Severity	Count	Status at end of cycle
Critical	0	—
High	3	F-1 closed (OTA reverted), F-3 closed (UNIQUE INDEX), D-1 closed (Newtonsoft 13.0.4); 1 pre-existing (F-2 path traversal) deferred to AZ-516
Medium	5	0 closed in audit; recorded as AZ-517..AZ-520
Low	5	0 closed; recorded as AZ-521 (bundle)

The audit found 1 regression introduced by cycle-1 work: F-1 (/get-update exposed plaintext encryption keys, AZ-183). Fix: full revert of AZ-183. F-3 was an amplification of a pre-existing race (RegisterDevice not having a UNIQUE INDEX); the audit closed it by adding env/db/06_users_email_unique.sql and consolidating RegisterDevice to delegate row insertion to RegisterUser.

Reverts after main code shipped	1	AZ-183 — same-day revert after security audit finding F-1
Skipped tests with documented reason	1	AZ-195 AC-1 (DB recovery test needs Docker socket access)
Test pass rate (E2E suite, end of Step 7)	44/44	After Dockerfile + healthcheck changes

Blocker Analysis

No blockers, but two notable mid-cycle pivots:

Event	Type	Prevention idea
User clarified mid-implement (2026-05-13) that the Loader is architecturally retired → AZ-197 was rescoped from cross-workspace to admin-only	Spec ambiguity discovered late	Add an "implicit assumptions" review gate to new-task Step 5 (Acceptance Criteria) that explicitly asks: which other workspaces does this touch? Are they still active?
Security audit found AZ-183 ships plaintext encryption keys → entire feature reverted same day	Threat model gap not caught at planning	Add a lightweight "what new authenticated endpoints / persistence does this introduce?" prompt to new-task Step 5; route any non-zero answer through a 5-minute threat-model check before complexity is finalized

Structural Snapshot

This is the first retro, so no delta computation. Snapshot persisted to _docs/06_metrics/structure_2026-05-13.md (placeholder — module-layout.md has 5 conceptual sub-components but only one ownership boundary in the registry, so cross-component edge counting is degenerate for this workspace).

Metric	Value	Source
Components (registry)	1 (Admin API)	_docs/02_document/module-layout.md
Conceptual sub-components	5	same
csproj projects	5	Azaion.AdminApi.sln (4 prod + 1 e2e)
Cycles in module graph	0	inspection (single deployable, no cross-component edges in the registry)
New Architecture violations this cycle	0	no cumulative_review_batches_*.md exists; verified by inspection of batch reviews — no Architecture-category findings
Resolved Architecture violations	0	—
Net Architecture delta	0	—
Public-API contract files (_docs/02_document/contracts/)	0	folder absent
Contract coverage %	n/a	n/a

Contract files are not part of this project's documentation set today. If future cycles introduce them (e.g., as part of a UI ↔ admin contract test effort), this section will start carrying real coverage numbers.

Trend Comparison

Top 3 Improvement Actions

1. Add a security threat-model micro-step to new-task Step 5 (Acceptance Criteria)

   • What: Two extra lines on every task spec — "New authenticated endpoints introduced: [list]" and "New persistent data introduced: [list]". If either is non-empty, the next sub-step is a 5-minute threat-model check (data flow, secrets exposure, replay surface). Output recorded in the task spec under ## Threat Model Notes.
   • Impact: catches the AZ-183-style "endpoint exposes plaintext key" class of regression at planning time, before the 3-pt budget is committed. Saves at least one cycle of implement → security-audit → revert per occurrence.
   • Effort: low (skill text edit + template addition).

2. Adopt the _cycleN_ batch-report naming convention starting cycle 2

   • What: Rename forward — every new batch report and code-review file in cycle 2+ uses batch_NN_cycleM_report.md and batch_NN_cycleM_review.md. Cycle-1 files stay as batch_NN_report.md for history. Update the implement skill's report-filename template.
   • Impact: prevents silent overwrite of cycle-1 batch reports when cycle 2's batch_07 lands (would currently collide with batch_07_report.md if that name was used). Already documented in the existing-code flow Step 10 — this enforces it.
   • Effort: low (one edit in .cursor/skills/implement/).

3. File the 8 carried-forward deploy drifts as Jira tickets in cycle 2 backlog

   • What: I, J, K, L, M, N, O are real backlog items (coverage gates, automated migrations, metrics + tracing, central logs, exporter, zero-downtime deploy, remote SSH wrapper). They currently live only as references in _docs/04_deploy/*.md. Promote them to AZ-tickets with story points.
   • Impact: makes operational debt visible alongside feature work; protects against silent erosion of the deploy plan over multiple cycles.
   • Effort: medium (≈ 30 min of ticket creation + sizing).

Suggested Rule / Skill Updates

File	Change	Rationale
.cursor/skills/new-task/SKILL.md	Add Step 5.5 — "Threat-Model Micro-Check" with the two prompts above	AZ-183 revert (cycle 1)
.cursor/skills/implement/SKILL.md	Update batch-report filename template to batch_NN_cycleM_report.md (and review file analogously)	Naming-collision risk on cycle 2
.cursor/rules/coderule.mdc	Add bullet: "Do not reuse retired numeric error codes (gaps are intentional)"	Batch 6 deletes codes 40 and 45 from ExceptionEnum — needs a rule so cycle 2 reviewers know not to fill the gap
_docs/04_deploy/-derived backlog	New AZ-* tickets for drifts I, J, K, L, M, N, O	Top action 3 above

Notes

• First retrospective. No prior baseline; cycle 2 will be the first one with delta numbers.
• Cycle health: green. 0 FAIL verdicts, 0 stuck agents, 0 auto-fix attempts, 44/44 E2E tests pass after Step 7's code edits. The single revert (AZ-183) was caught by the next-step security audit and resolved before deploy — the system worked, but the goal of the threat-model micro-check is to catch it one step earlier.
• Operator burden after this cycle: the 8 carried-forward drifts represent ≈ 22 story points of follow-up infrastructure work (rough sizing — to be confirmed when filed as tickets per Top Action 3).
