Oleksandr Bezdieniezhnykh cbbb26bd28 [AZ-487] [AZ-488] chore: cycle 2 Step 15 skip + record JWT-attach script rot
Step 15 (Performance Test) — skipped per gate (option B). Recording two
deferred items in the existing perf leftover:

* PT-07 + PT-08 remain Deferred. Both NFRs depend on the same
  baseline-capture harness that has not landed; the integration-test
  fixtures needed for PT-08 already exist (UavUploadTests +
  UavTileImageFactory), so PT-08 attaches to the same harness as PT-07
  when implemented.
* scripts/run-performance-tests.sh PT-01..PT-06 currently return 401
  against the post-AZ-487 build because they attach no Bearer token.
  Script must mint an HS256 token from JWT_SECRET at script start
  before any curl call. Tracked in the leftover so PT-01..PT-06 are
  runnable again the same cycle PT-07/PT-08 are activated.

No code change in this commit — leftover + state advance only.

Leftover — PT-07 perf harness + cycle 1 perf run

  • Timestamp: 2026-05-11T07:05:00Z
  • Origin: autodev cycle 1, Step 15 (Performance Test)
  • Blocker class: non-user-input — work was deferred at the Step 15 user gate; no missing user decision blocks completion.

What was deferred

  1. PT-07 implementation in scripts/run-performance-tests.sh: capture pre-change baseline for GetTilesByRegionAsync p95 latency, run post-change measurement, compute the ratio, and assert ratio ≤ 1.10. PT-07 was recorded as a documentation entry during Step 12 (_docs/02_document/tests/performance-tests.md + traceability-matrix.md "NFRs → Test Mapping" section) but the runner script does not yet have the corresponding scenario.
  2. Active perf run of PT-01..PT-06 against the post-AZ-484 build. The runner exists; it requires docker-compose up on the dev host. Not executed this cycle (per the meta-rule "ask before kicking off Docker / long-running perf operations").

Why it is safe to defer

  • AZ-484 functional correctness validated by 5 dedicated AZ-484 integration tests (Step 11). The DB read paths exercised by PT-07 are the same ones exercised by MostRecentAcrossSourcesSelection_AZ484_AC2 etc.
  • The post-AZ-484 SQL uses the same idx_tiles_unique_location_source index as the contract specifies; structurally there is no new full scan, join, or lock added vs. pre-AZ-484.
  • Cycle 1 perf run is recorded as Unverified (not Fail) per the test-run perf-mode rules — gate does not block deploy.

Replay actions for next /autodev invocation

When the next cycle's autodev runs, before any new tracker write or before re-entering Step 15 in cycle 2:

  1. Add PT-07 to scripts/run-performance-tests.sh:
    • Capture a pre-change baseline by checking out the parent of the AZ-484 commit (git rev-parse HEAD~N where N points at the AZ-484 batch), running the existing PT-03/PT-04 region scenarios, and recording the GetTilesByRegionAsync timings (the repository already logs slow query warnings at >500 ms — extend that log line to include median/p95 captured per call window).
    • Run the post-change measurement against the current HEAD.
    • Compute the p95 ratio and fail when > 1.10.
  2. Bring up the docker stack (docker-compose up --build -d) and run the full perf script with the user's explicit go-ahead.
  3. Capture results into _docs/06_metrics/perf_<YYYY-MM-DD>_cycle<N>.md.
  4. Once results are recorded, delete this leftover file.

AZ-488 follow-on: PT-08 (UAV upload latency)

The AZ-488 commit added PT-08 (UAV tile batch upload latency) to _docs/02_document/tests/performance-tests.md with Status Deferred because it reuses the same harness expansion as PT-07 (baseline capture + p95 ratio). When PT-07's runner-script scenario is implemented in step 1 above, add the PT-08 scenario in the same commit — the integration-test fixtures already exist (SatelliteProvider.IntegrationTests/UavUploadTests happy-path JWT + UavTileImageFactory.CreateRandomJpeg). After PT-08 runs, flip the Status line in performance-tests.md from Deferred to active. This keeps cycle 1 retro Action 2 satisfied for both NFRs.

AZ-487 follow-on: scripts/run-performance-tests.sh attaches no Bearer token (cycle 2 carry-over)

Cycle 2's Step 15 (Performance Test) skip-decision uncovered an additional latent blocker: scripts/run-performance-tests.sh calls every /api/satellite/* endpoint without an Authorization header. Post-AZ-487 every such call returns HTTP 401 — the script is currently broken end-to-end, not just for PT-07/PT-08. Whoever picks up the harness work in step 1 above MUST also:

  1. Read JWT_SECRET from the host env (the same value used by docker-compose.yml).
  2. Mint a short-lived HS256 token at the top of the script (mirror SatelliteProvider.IntegrationTests/JwtTestHelpers.MintValidToken — small python3 -c or jwt CLI call; do not commit the dev placeholder secret).
  3. Add the token to every curl invocation via -H "Authorization: Bearer $JWT".
  4. Skip-the-test-cleanly when JWT_SECRET is unset rather than running and failing on every call.

This is purely script work; no production code needs to change. Tracking it here so PT-01..PT-06 are runnable again the same cycle PT-07/PT-08 are activated.

Tracker action (none required this cycle)

This leftover does NOT require a Jira ticket on its own — it tracks deferred process work, not user-visible scope. If the perf comparison reveals a regression next cycle, that finding will create a Jira bug; until then there is nothing to file.
