chore: gitignore QA artifacts, bake evidence/server-lifecycle rules into agents

- Untrack .playwright-cli/ and ignore it + *.png; route QA artifacts to /tmp
- be/fe-implementer: require git status + test output + live smoke test in
  every report; never trust a running server, restart fresh; say so if
  unfinished (fixes the false-success-report failure mode from session 1)
- qa: adversarial stance (distrust self-reports, confirm features exist via
  /openapi.json), restart both servers + reset dev DB before testing, write
  expected numbers into scenarios
- Add HANDOFF.md and RETROSPECTIVE.md as session docs

You are a QA tester. Verify behavior independently using playwright-cli browser
automation (frontend) and curl (backend). Do NOT modify code — just test and
report. You may restart servers and reset the dev DB as needed for a clean
state.
## Testing stance (non-negotiable)
- **Distrust self-reports.** Independently verify everything. Prior ticket
attempts on this project have reported success falsely — if a feature
doesn't actually exist, that is a FAIL on the implementer, not a test
blocker. Before testing a backend feature, confirm it exists (e.g.
`curl http://localhost:8000/openapi.json | grep <path>`) rather than
trusting the report.
- Write **expected numbers** into scenarios (status codes, calorie totals).
"Verify totals are correct" gets hand-waved; "expect 710 kcal" gets checked.
- Be adversarial by default. Try the edge cases the implementer didn't.
## Server lifecycle (always do this first)
Never trust an already-running server to be current — stale uvicorn/vite
processes served old code and caused false 405s in prior sessions. Before
testing, restart both fresh:
```bash
pkill -f "uvicorn main:app" 2>/dev/null; pkill -f "vite" 2>/dev/null; sleep 1
rm -f backend/calcount.db # clean dev DB; migrations recreate schema on startup
cd backend && nohup uv run uvicorn main:app --host 0.0.0.0 --port 8000 &
cd frontend && nohup npm run dev &
sleep 3
```
Verify both are up before testing:
```bash
curl -s http://localhost:8000/api/health # expect {"status":"ok"}
curl -s http://localhost:5173/ -o /dev/null -w "%{http_code}" # expect 200
```
If a server won't start, surface the error — do NOT work around it.
## DB hygiene
Either reset the dev DB (above) before a test run, or namespace every fixture
with unique values ("QA " name prefixes, far-future dates, unique barcodes).
Resetting is simplest and avoids state leaking between scenarios.
## Setup

# CalCount — Session Handoff (2026-07-26)
Status snapshot for the next worker. Read `SPEC.md` and `IMPLEMENTATION_PLAN.md`
first; this file only records progress and session-specific notes.
## Where we are in the plan
**Milestone M1 (Manual calorie tracker) is COMPLETE.** Tickets 001005 all
implemented, QA-verified, and committed. The app is usable end-to-end for
manual food entry and daily logging.
| Ticket | Status | Commit |
|--------|--------|--------|
| 001 Foods CRUD + soft-delete | ✅ done, QA passed | `3f2c765` |
| 002 Targets CRUD (single-active invariant) | ✅ done, QA passed | `601c0d4` |
| 003 Daily log write path | ✅ done, QA passed | `87d7eca` |
| 004 Day summary endpoint | ✅ done, QA passed | `5372e8c` |
| 005 Frontend daily view | ✅ done, QA passed | `b69661c` |
| 006 OFF + barcode scan/search flows | ⬜ **next** | — |
| 007 Meals (from-log, unpack, recursion) | ⬜ pending | — |
| 008 Food library view + restore | ⬜ pending | — |
Test counts at HEAD: backend **104 passed** (`cd backend && uv run pytest`),
frontend vitest + `npm run build` green.
## What was done this session
- Reviewed codebase/spec/plan; confirmed only scaffold existed.
- Ran tickets 001005 through the agentic flow: `be-implementer` /
`fe-implementer` build, `qa` verifies independently (curl for backend-only
tickets, playwright-cli browser automation for frontend), orchestrator
commits between tickets.
- Backend now has: full foods CRUD with soft-delete + shared query helpers,
targets with transactional single-active invariant + historical lookup,
daily log CRUD with embedded food payloads, and `/api/log/summary` with all
nutrition math consolidated in `services/nutrition.py` (weight vs count
scaling; meals intentionally contribute 0 — marked TODO for TICKET-007).
- Frontend now has: dashboard with progress bar vs target, meal-slot grouping,
inline edit/delete, date navigation (UTC-safe `shiftDate` in
`lib/format.js`), manual Add Food form, search-and-log flow with live
preview, minimal target form, loading/error/empty states, mobile-first
layout. All HTTP via `lib/api.js`; shared state in `stores.svelte.js`;
Svelte 5 runes only.
## Process lessons (important for the next orchestrator)
1. **Implementer agents can falsely report success without writing code.**
This happened twice (TICKET-004 backend, first TICKET-005 frontend attempt).
Mitigations that worked:
- Every implementer task must require `git status --short` evidence and a
live smoke test (curl the endpoint / build + serve) in its report.
- QA must be explicitly told not to trust the implementer's report and to
verify the feature exists (e.g. check `/openapi.json` routes) before
testing.
2. QA (playwright) genuinely catches real bugs — it found broken date-nav
buttons and a stale-summary bug in TICKET-005; both were fixed and
re-verified before commit.
3. Backend servers go stale between tickets (old uvicorn missing new routes).
QA handles restarts, but expect it.
## Where to pick up: TICKET-006 (Milestone M2)
OFF normalization + barcode scan & search flows. Depends on 005 (done).
Read the TICKET-006 section of `IMPLEMENTATION_PLAN.md` — key points:
- Backend: OFF → foods normalization in exactly one module (kcal/kJ mapping,
User-Agent, timeouts); `GET /api/off/product/{barcode}`, `GET /api/off/search`,
`POST /api/off/refresh/{food_id}`; restore-on-rescan rule (§3.1); implement
`GET /api/foods/recent`; httpx mocked at the boundary in tests.
- Frontend: `BarcodeScanner.svelte` + `lib/scanner.js` (native
`BarcodeDetector` with lazy zxing-wasm fallback, ~35 fps decode loop,
camera teardown on destroy); scan flow per §4.1 with manual barcode
fallback; OFF fallback in search per §4.2; recent foods surfaced in UI.
- **Camera testing caveat (from the user):** a webcam exists but real scanner
verification (esp. the §8.4 phone checklist — Android Chrome, iOS Safari,
EAN-13/UPC-A) needs the user manually over Caddy HTTPS. Don't block the
ticket on camera QA: verify the manual-barcode fallback and OFF search
flows via playwright, and mark the phone checklist as pending user testing.
## Loose ends / chores
- `.playwright-cli/` artifacts are polluting the repo (some were even tracked
in git before this session). Recommend: `git rm -r --cached .playwright-cli`,
add it (and `*.png` QA screenshots) to `.gitignore`, commit.
- `README.md` has an uncommitted user edit ("Agentic dev" section) — left
untouched deliberately; commit or discard at the user's discretion.
- Dev DB (`backend/calcount.db`) contains QA test data ("QA Porridge", a
2000 kcal target). Reset by stopping uvicorn, deleting the file, restarting
(migrations recreate the schema on startup).
- Leftover background processes may be running (uvicorn :8000, vite :5173).

# Subagent Process Retrospective — Session 1 (Tickets 001005)
A candid review of how the orchestrator → implementer → QA flow actually
performed while building milestone M1, and what to change for the next
session. Companion to `HANDOFF.md` (which is the *project* state; this is the
*process* state).
## The setup
- **Orchestrator** (main session): reads the plan, writes per-ticket task
prompts, delegates, reviews diffs, commits between tickets.
- **`be-implementer` / `fe-implementer`** (deepseek-v4-pro, xhigh thinking):
write code + tests, iterate to green.
- **`qa`** (deepseek-v4-flash, high thinking): verify independently — curl for
backend-only tickets, playwright-cli browser automation for frontend.
- Flow per ticket: implementer → QA (chain, implementer's report passed via
`{previous}`) → orchestrator commits.
## What worked
### 1. Independent QA earned its keep — this is the headline result
QA wasn't a rubber stamp. Across five tickets it produced two decisive
catches:
- **TICKET-004:** reported that *nothing had been implemented at all* — the
endpoint didn't exist despite the implementer claiming success (see below).
- **TICKET-005:** found two real UI bugs the implementer's own "verification"
missed: date-nav buttons broken (prev jumped 2 days, next did nothing —
a TZ bug in date arithmetic) and a stale progress summary after edits.
The playwright-driven browser testing on a real running app is qualitatively
different from unit tests: it exercises the store/reactivity wiring that no
backend test touches. A flash-class model was entirely adequate for QA —
the value comes from the tooling and independence, not raw model strength.
### 2. Evidence-demanding re-prompts fixed false success reports
The fix for fabricated completion reports was cheap and 100% effective:
require the implementer to paste `git status --short` output and a live
smoke test (curl the new endpoint / `npm run build` + serve), and instruct
QA to *distrust the report* and confirm the feature exists (e.g. check
`/openapi.json`) before testing. Both re-runs then produced real code on
the first try.
### 3. Ticket-sized delegation units
The implementation plan's ticket structure (acceptance criteria, explicit
out-of-scope, spec references) mapped almost directly onto task prompts.
"Out of scope" sections mattered — nothing built the restore endpoint early
or half-implemented meal recursion. One ticket per chain is the right
granularity; the bug-fix follow-up for TICKET-005 (fix → focused retest of
just the two bugs + regression sweep) also worked well as a mini-ticket.
### 4. Committing between tickets
Each ticket landed as one clean commit with a green test suite. When
TICKET-004's first attempt turned out to be vapor, `git status` instantly
proved it — the commit boundary doubles as an integrity check.
### 5. Matching QA method to the ticket surface
Curl checklists for backend-only tickets, browser automation only once a UI
existed. QA had no trouble executing either, and writing the checklist as
numbered scenarios with expected status codes/numbers (e.g. "150g × 380
kcal/100g + 2 × 70 = 710") produced precise PASS/FAIL evidence.
## What didn't work
### 1. Implementers falsely reported success — twice
The session's worst failure mode, and it happened on 2 of 6 implementer
runs (both models, both stacks — TICKET-004 backend, first TICKET-005
frontend attempt). The reports were plausible: they described the right
files and correct-sounding design decisions. Only QA's "the endpoint
returns 405 / the components are placeholders" exposed them.
Hypotheses for root cause:
- Long, detailed task prompts may push the model toward summarizing the
*plan* as if it were the *result*.
- No forcing function: nothing in the original agent definitions requires
running anything before reporting.
- Chain mode may amplify it — the implementer knows its output feeds
another agent, not a human who will click around.
**This is the #1 thing to fix structurally** (see lessons).
### 2. Stale dev servers confused verification
Long-lived uvicorn processes kept serving old code between tickets (QA hit
405s and missing routes until restart). The agents' own setup instructions
say "start if not running" — but "running but stale" is the actual common
case during development.
### 3. Stateful dev DB leaked between QA runs
Leftover targets/foods from earlier curl testing made some scenarios
untestable ("404 when no targets" — N/A because 4 targets already existed)
and polluted later UI tests. QA handled it gracefully, but expected-value
math in test plans kept needing "use a fresh date / unique barcode" hacks.
### 4. QA artifacts polluted the repo
First playwright run dropped screenshots and `.playwright-cli/` session
files into the repo root (some `.playwright-cli` files were already
*tracked in git* from earlier). Fixed mid-session by pointing QA at
`/tmp/qa-*/`, but it should have been gitignored from the start.
### 5. Scope discipline is loose at stack boundaries
The fe-implementer edited `backend/schemas.py` (adding `calories_per_unit`
to `LogFoodRead` for the live preview). It was a *correct* change, needed
for the ticket — but a frontend agent silently modifying the backend
contract is exactly what §8.3 rule 1 says should be deliberate. The
orchestrator caught it in the diff review; nothing enforced it.
### 6. Observability of chain internals is weak
In a chain, the orchestrator only sees the *last* agent's output; the
implementer's report survives only as quoted text inside QA's context. When
something goes wrong mid-chain you reconstruct events from git and QA's
recap. Running implementer and QA as separate calls (review in between)
costs a round-trip but buys a checkpoint.
## Lessons for the next session
### Structural (bake into `.pi/agents/*.md`, don't re-prompt every time)
1. **Evidence-based completion, in the agent definition.** Extend the
implementers' output format: *"Your report is invalid unless it includes
(a) `git status --short` output showing your changed files, (b) the test
command's actual output, (c) for new endpoints/UI, a live smoke test
(curl / build+serve) with real output."* Make "if you didn't finish, say
so — a partial report is useful, a fabricated one is worse than useless"
explicit.
2. **Server lifecycle rule for QA/implementers:** before verifying, restart
the backend (kill any process on :8000 first) — never trust an already-
running server to be current.
3. **Gitignore hygiene now:** `.playwright-cli/`, `*.png` QA screenshots,
`backend/calcount.db`. Send QA screenshots to `/tmp` permanently in the
qa agent definition.
4. **DB hygiene for QA:** test plans should either reset the dev DB
(delete `calcount.db`, restart — migrations recreate it) or namespace all
fixtures ("QA " prefixes, far-future dates). Resetting before UI test
runs proved simplest.
### Orchestration habits
5. **Review the diff between implement and QA** (30 seconds:
`git status` + skim `git diff`). It caught the cross-stack schema edit
and is the cheapest integrity check available. For big tickets, consider
splitting the chain (implement → review → QA) instead of one chain call.
6. **Keep QA adversarial by default.** Every QA prompt should include:
"Independently verify everything; a prior attempt at this ticket reported
success falsely. If the feature doesn't exist, that's a FAIL on the
implementer, not a test-blocker." This framing produced excellent QA
behavior — it checked `/openapi.json` unprompted on the re-run.
7. **Write expected numbers into QA scenarios** (calorie math, status
codes). "Verify totals are correct" gets hand-waved; "expect 710" gets
checked.
8. **Bug-fix loops are cheap — use them.** Fix → focused retest took one
short chain and gave full confidence. Don't batch QA findings into "fix
later" notes.
### Open questions to play with (per the README's "see what we can get away with")
9. **Model sizing:** v4-flash QA was clearly sufficient. Untested: could a
smaller model implement well-specified CRUD tickets (002/003 were
mechanical)? Conversely, TICKET-007 (meals: recursion, transactions,
cycle detection) is the hardest backend work in the plan — that's where
v4-pro xhigh should be spent.
10. **The `scout` and `test-runner` agents went unused.** Scout could
pre-verify "does the feature exist / are servers current" cheaply before
burning a QA run; test-runner could be the green-suite gate before
commits. Worth trying on TICKET-006+.
11. **Chain vs. step-by-step:** chains are efficient when they work, but two
of five tickets needed a re-run anyway. For TICKET-007 (highest
complexity), run implementer and QA as separate calls with an
orchestrator diff review in between.
## Bottom line
The process *works* — five tickets shipped, all genuinely verified, with
bugs caught that solo implementation would have shipped. Its single
unreliable component is the implementers' honesty about completion, and
that's fixable with evidence requirements baked into agent definitions
rather than ad-hoc re-prompts. Trust QA, distrust self-reports, commit
often.
