+# pragent — Update Design
+
+**Date:** 2026-08-21
+**Status:** Approved (brainstorm, 2026-08-21)
+**Replaces:** none — additive + behavioral. Existing `docs/plans/2026-08-04-pragent-design.md` stays authoritative on architecture.
+
+## Problem
+
+The pilot has been live long enough to surface pain that the original design didn't
+cover:
+
+1. **Two labels to remember.** `AI-REVIEW` (gate) + `AI-USAGE` (opt-in for the
+   cost block) are per-PR. Every new contributor reads the README wrong at least
+   once. Reviews that the team *wanted* are skipped because nobody labeled; reviews
+   we *don't* want still run because the label is sticky.
+2. **Token numbers are unreadable.** `Total Tokens: 2071025 in / 17303 out`
+   requires a mental carry. The pilot already measures the tokens; the rendering
+   just doesn't help.
+3. **Cost is anchored on one provider.** The pilot runs free (headroom/glm-5.2)
+   but the only equivalent-cost line is Claude Sonnet. We can't answer "what would
+   this have cost on GPT / Gemini / Grok?" without running the CLI on a different
+   model.
+4. **The PR summary is operational, not useful.** A lens-fanout run posts
+   `Multi-lens review of repo#index (sha X). Lenses: security,perf. Findings:
+   critical=0 high=1 medium=2 low=1.` That tells a reviewer *how the bot worked*,
+   not *what they should look at*. Real products post a risk verdict, a
+   file-by-file walkthrough, and a test-coverage note.
+5. **Triage noise is the dominant failure mode** in every competitor (CodeRabbit,
+   Qodo, Greptile, DoorDash). We already address most of it (severity_floor,
+   per-file cap, cross-lens agreement, tone-strip), but two cheap wins are left on
+   the table: a per-PR *merge confidence* badge, and a richer severity scale that
+   includes `trivial` / `info` (CodeRabbit's pattern).
+
+This update also distills lessons from a 30-article survey of AI code review
+products (CodeRabbit, Qodo/Merge + PR-Agent, Greptile, GitHub Copilot code
+review, Gemini Code Assist, qodo-ai/pr-agent, anc95/ChatGPT-CodeReview, Sourcery,
+Danger, plus the security literature around the April 2026 prompt-injection
+disclosures). Where we already match the state of the art, this update notes it
+and moves on; where a competitor's pattern is genuinely better, it lands here.
+
+## Decisions
+
+| Question | Decision | Why |
+|---|---|---|
+| Trigger | `.pr-review.json:enabled` on the PR's base branch | Repo opt-in replaces labels. No per-PR manual step. Trust stays on base. |
+| Default when `.pr-review.json` is absent | Disabled | Explicit opt-in. Mirrors "labels fully removed." |
+| Cost model | Always render when usage data is present | Drop the `report_usage` parameter + `AI-USAGE` label + `PRAGENT_USAGE_ALWAYS` env. |
+| Token rendering | `1,234,567 (1.2M)` | Python `f"{n:,}"` + short suffix only when `n ≥ 1000`. |
+| Multi-provider cost | Markdown table in the collapsible usage block | Replaces the single Sonnet line. Default compare set: Sonnet, GPT-5, Gemini 2.5 Pro, Grok 4.5. |
+| Summary depth | Add `walkthrough` / `risk_verdict` / `test_coverage` to the agent JSON; Python fallback for lens synthesis | Agent produces the rich text; Python derives the same three when the lens fan-out is engaged. |
+| Severity scale | Extend from 4 → 6 levels: add `trivial` + `info` | Matches CodeRabbit. Backward compat (unknown → medium). |
+| Merge confidence | 1–5 integer in the review header. Python-computed. | Stole the badge idea from Greptile. |
+| Reachability demotion | Defer | Needs the security graph. Note in §7. |
+| Rules mining from feedback | Defer | `feedback_harvest` / `feedback_analyze` exist; distillation is a separate effort. |
+| Sequence diagrams / T-rex / cross-repo | Skip | Too heavy for the pilot. |
+
+## 1. Label removal + repo opt-in
+
+### `.pr-review.json` schema delta
+
+```diff
+ {
+  "enabled": true,
+   "focus": [...],
+   "exclude_paths": [...],
+   ...
+ }
+```
+
+`enabled` is a top-level boolean, default `false`, read from the **base branch**
+(unchanged trust rule — `fetch_repo_config(ref=base_ref)` already handles this).
+
+### Webhook behavior (`pilot/webhook_server.py`)
+
+- Remove constants `AI_REVIEW_LABEL`, `AI_USAGE_LABEL`. Remove
+  `_labels_have_ai_review`. Remove the `report_usage` plumbing from
+  `_handle_pull_request` and `_run_review`.
+- New helper `is_repo_enabled(api, repo, ref, token) -> bool` in `webhook_server.py`
+  (or reused via `fetch_repo_config` — see below). `False` on any failure
+  (404, parse error, missing key, malformed value). Logs the reason to stderr.
+- `_handle_pull_request` order of operations:
+  1. `action in SKIP_ACTIONS` → `200 ignore`
+  2. base_ref present + fetch config
+  3. `if not config.get("enabled")` → `200 "skip (repo not opted in)"`
+  4. claim in-flight slot
+  5. thread off `_run_review`
+- Pre-claim gate keeps opted-out repos from consuming concurrency slots on
+  bursts. One extra `GET contents/.pr-review.json` per PR event (404 for
+  unconfigured repos) — negligible.
+
+### `pilot/ai_review.py` cleanup
+
+- Delete `AI_REVIEW_LABEL`, `AI_USAGE_LABEL` constants.
+- Delete `pr_has_label()` helper (its only call sites were the AI-USAGE
+  re-reads at render time).
+- Drop the `report_usage: bool` parameter from `review_pr()`. Always render
+  the collapsible usage block when `usage` is not None.
+- Remove the two `PRAGENT_USAGE_ALWAYS` references (env reads).
+- Extend `parse_repo_config()` to extract `enabled` (validate is bool,
+  default False).
+- Extend `effective_config()` to preserve `enabled` through the style-defaults
+  merge.
+
+### Docs
+
+- `README.md`: rewrite "Label a PR `AI-REVIEW`" + "add the AI-REVIEW label" to
+  "commit `.pr-review.json: {"enabled": true}` to the default branch." Drop the
+  AI-USAGE paragraph. Update the flow diagram.
+- `pilot/README-webhook.md`: replace onboarding steps. Drop the per-PR label
+  ceremony.
+- `pilot/README.md` (CI-step path): if it still references labels, remove.
+
+## 2. Token humanization
+
+New helper in `pilot/ai_review.py`:
+
+```
+def fmt_tokens(n: int | None) -> str:
+    """1234567 -> '1,234,567 (1.2M)'; 0 -> '0'; <1000 -> comma-form; None -> '?'."""
+```
+
+Rules:
+- `None` → `"?"`.
+- `n < 1000` → `f"{n:,}"` (no short suffix — most findings have ~tens of tokens).
+- `1000 ≤ n < 1_000_000` → `f"{n:,} ({n/1000:.1f}K)"`, drop trailing `.0`.
+- `1_000_000 ≤ n < 1_000_000_000` → `f"{n:,} ({n/1_000_000:.1f}M)"`.
+- else `...B`.
+- Negative inputs → `"?"` (defensive — never expected from usage dicts).
+
+Apply in:
+- `pilot/ai_review._render_collapsible_usage` — input, output, reasoning,
+  cache_read, cache_write, total.
+- `pilot/ai_review.inline_comment_body` — the `🪙 ~N tok (...)` per-finding
+  line.
+
+Tests: `test_fmt_tokens` golden vectors — `0`, `42`, `999`, `1000`, `1234`,
+`1_234_567`, `1_234_567_890`, `None`, `-1`.

+Notes on derivation:
+- Gemini 2.5 Pro publishes a tiered range (`$1.25–$2.50` in, `$10–$15` out,
+  `$0.125–$0.25` cached). Midpoints are taken for a single line; the
+  `compare_against` field lets a repo override per-key if precision matters.
+- Providers without a separate cache_write charge (OpenAI, Gemini, Grok) set
+  `cache_write = input` so the existing `cost()` formula continues to work
+  without a branch on provider.
+- `cost_target` (the highlighted single line) and `compare_against` (the table)
+  are independent fields — see §3.2.
+
+### 3.1 Render
+
+Replace the single `**Est. cost on {provider}**: $X.XX` line in
+`_render_collapsible_usage` with a compact markdown table:
+
+```
+**Equivalent cost on paid providers** (this run's measured tokens):
+
+| Provider | Cost |
+|---|---:|
+| Claude Sonnet 5 | $4.32 |
+| GPT-5 | $2.71 |
+| Gemini 2.5 Pro | $4.04 |
+| Grok 4.5 | $4.32 |
+```
+
+Sort cheapest-first. Skip rows whose cost is `$0.00`. Bold the row matching
+`cost_target` (the user-selected highlight).
+
+### 3.2 Config
+
+`.pr-review.json`:
+```json
+{
+  "enabled": true,
+  "cost_target": "claude-sonnet-5",
+  "compare_against": ["claude-sonnet-5", "gpt-5", "gemini-2.5-pro", "grok-4.5"]
+}
+```
+
+`parse_repo_config()`:
+- Validate each key exists in `PRICES`. Drop unknowns to stderr (keeps
+  `cost_model._resolve_price_target`'s typo-reporting consistent).
+- Cap the list at `CONFIG_MAX_LIST_ITEMS` (12).
+- Default when absent: `["claude-sonnet-5", "gpt-5", "gemini-2.5-pro",
+  "grok-4.5"]`.
+
+### 3.3 Tests
+
+`tests/pilot/test_cost_model.py`:
+- Add equivalent-cost golden vectors against the new price keys.
+- Update `test_observed_report_prices_every_model` and
+  `test_report_renders_every_requested_model` to cover the new keys.
+- Add `test_compare_against_parsing` (valid / unknown / over-cap / missing).
+
+## 4. Richer review summary
+
+### 4.1 Schema additions (agent prompts + `SYSTEM_PROMPT`)
+
+```json
+{
+  "walkthrough": [
+    "file X: does Y",
+    "file Z: refactors W"
+  ],
+  "risk_verdict": "Medium risk: changes auth middleware without adding tests.",
+  "test_coverage": "No tests for behavioral change in pilot/foo.py."
+}
+```
+
+Rules (added to `.opencode/agents/pragent.md`, each lens agent `.md`, and the
+ollama `SYSTEM_PROMPT`):
+- `walkthrough`: 2–6 bullets, file- or change-grouped, plain prose (no
+  severity emoji). Skip if the diff is one obvious line.
+- `risk_verdict`: exactly one line. Lead with `Low|Medium|High|Critical risk:`
+  followed by a concrete reason grounded in the diff.
+- `test_coverage`: short string. One of
+  `Tests added` / `Tests changed` / `No tests for behavioral change` /
+  `No test files in repo` / a repo-specific free-text override from
+  `instructions`.
+
+### 4.2 Parsing
+
+Extend `parse_review_output(text)` and the lens fan-out's synthetic-text
+builder (`pilot/opencode_review.run_lenses_review`) to emit these three
+fields in the final JSON block. Empty defaults preserve backward compat with
+agents that haven't been re-deployed yet.
+
+### 4.3 Python fallback (when fields are empty)
+
+The multi-lens fan-out already synthesizes the findings JSON in Python today;
+add a `_synthesize_summary_fields(findings, diff) -> dict` helper that
+computes:
+- `walkthrough`: group `merged` findings by `path`, one bullet per path
+  containing the peak severity emoji and the first-problem truncated to ~80
+  chars. If `merged` is empty, list `changed_files(diff)` with the size of
+  the diff as the body ("`pilot/foo.py` — +12 lines").
+- `risk_verdict`: from `sev_counts` and `_multi_lens` flags:
+  - any critical → `Critical risk: <N> critical finding(s).`
+  - any high → `High risk: <N> high finding(s).`
+  - any medium → `Medium risk: <N> medium finding(s) (<lens> lens).`
+  - else `Low risk: clean or minor nits only.`
+- `test_coverage`: scan `changed_files(diff)` with `is_test_path()`. Three
+  buckets:
+  - any test path changed alongside non-test paths → `Tests added` (or
+    `Tests changed`).
+  - non-test paths present, no test path → `No tests for behavioral change in
+    <first non-test path>.`
+  - no test paths at all and non-test paths present → `No tests for
+    behavioral change in <first non-test path>.` (same as above; the
+    distinction "no test files in repo" needs a tree scan — keep it simple
+    for v1).
+
+### 4.4 Render
+
+Extend `format_review_body()` to render three new sections between
+`### Summary of Changes` and `### Key Risks & Concerns`:
+
+```
+### Risk Verdict
+🟡 Medium risk: changes auth middleware without adding tests.
+
+### Walkthrough
+- `pilot/foo.py` — adds retry logic for transient Gitea API errors
+- `pilot/bar.py` — extracts shared header parser
+
+### Test Coverage
+No tests for behavioral change in pilot/foo.py.
+```
+
+Each section renders an `_No <section> provided._` placeholder when empty
+(matches the existing `Summary of Changes` / `Key Risks & Concerns` collapse
+behavior).
+
+### 4.5 Tests

+## 6. Stolen ideas
+
+### 6.1 Merge confidence 1–5 (Greptile)
+
+New function `merge_confidence(findings: list[dict]) -> int` in
+`pilot/ai_review.py`:
+
+```
+start at 5
+-1 if any critical finding
+-1 if any high finding
+-1 if any medium finding
+-1 if any _multi_lens: True finding (cross-lens agreement = harder to dismiss)
+clamp to [1, 5]
+```
+
+Render in `REVIEW_HEADER`:
+
+```
+🤖 **AI Review** · pragent pilot · glm-5.2:cloud · `abc12345` · Merge confidence: 3/5 🟡
+```
+
+Badge map: 5/4 = 🟢, 3 = 🟡, 2 = 🟠, 1 = 🔴.
+
+Tests: golden vectors for all 5 score branches.
+
+### 6.2 Add `trivial` + `info` severity levels (CodeRabbit)
+
+Extend `SEVERITIES` and `SEVERITY_RANK`:
+
+```
+SEVERITIES = ("critical", "high", "medium", "low", "trivial", "info")
+SEVERITY_RANK = {"info": -1, "trivial": 0, "low": 1, "medium": 2, "high": 3, "critical": 4}
+```
+
+Update `_severity_badge` emoji map (`trivial`/`info` = ⚪). Update
+`apply_repo_config` threshold semantics so `medium+` still means what it
+meant (only `low` ranks below `medium` is unchanged). Update agent prompts
+to permit emitting `trivial` / `info`. Backward compat: `_normalize_finding`
+already coerces unknown severities to `medium`.
+
+Tests: existing `test_apply_repo_config` cases keep passing; add
+`test_severity_threshold_respects_new_levels` and
+`test_unknown_severity_normalizes_to_medium`.
+
+### 6.3 Reachability-aware severity demotion — DEFER
+
+CodeRabbit Security demotes severity by one level when a vulnerability is
+unreachable / only theoretically exploitable. We can't compute reachability
+without the security graph. Document in §7 and revisit when a Code-Rabbit-
+style graph index lands.
+
+### 6.4 Rules mining from feedback — DEFER
+
+`pilot/feedback_harvest.py` + `pilot/feedback_analyze.py` exist. A future
+`pilot/learn_rules.py` cron job will distill FP-vote signals into
+`.pr-review.learned.json` and merge into `instructions`. Document in §7.
+
+### 6.5 Sequence diagrams / T-rex / cross-repo — SKIP
+
+Too heavy for the pilot's footprint. Document in §7.
+
+## 7. Deferred (not in this update)
+
+- **Reachability-aware severity demotion.** Requires a Code-Rabbit-style
+  reachability graph over the repo.
+- **Rules mining from feedback.** A `learn_rules.py` job that consumes the
+  feedback DB and writes `.pr-review.learned.json`. `feedback_harvest` /
+  `feedback_analyze` are the substrate.
+- **Sequence diagrams / T-rex sandbox / cross-repo review.** Three features
+  Greptile / Qodo highlight. All require either a code graph index (heavy
+  precompute) or sandbox runtime execution (separate infra). Skip.
+- **Per-finding confidence scores.** Greptile publishes a 0–5 score on every
+  comment. We deliberately stay on severity — confidence on findings
+  requires the agent to self-estimate, which is unreliable without a
+  cross-lens consensus check. The merge-confidence badge (§6.1) is the
+  higher-signal version of the same idea.
+- **`Fix with Cursor` handoff.** Greptile ships a one-click "send all findings
+  to Cursor/Codex/Claude Code." Our users *are* the bot's host, not an
+  external coding IDE. Skip.
+- **Cost-model batch column.** The cost model already prices batch at 50%;
+  the PR-review path will never use it (stateful agent loops aren't
+  batchable). Keep the column for completeness, no new work.
+
+## 8. Risk register
+
+| Risk | Mitigation |
+|---|---|
+| Webhook floods the API with `.pr-review.json` fetches on a large owner | One `GET` per PR event, mostly 404. Documented acceptable. The dedicated `/health` already reports inflight count. |
+| `.pr-review.json:enabled` set on a high-traffic repo creates surprise review load | The README will document the opt-in explicitly. The webhook's `PRAGENT_MAX_CONCURRENT_REVIEWS` already bounds the spawn rate. |
+| New severity levels (`trivial` / `info`) break repos that filter on `medium+` | `apply_repo_config` threshold semantics preserve the rank of `low` and `medium`. `trivial` ranks below `low`, `info` below `trivial`. New filters naturally include them. |
+| Token humanization loses precision a maintainer relies on | `fmt_tokens` always keeps the full comma-separated number; the short suffix is a parenthetical. |
+| Multi-provider cost table is misleading when a provider has tiered pricing | `compare_against` is a per-repo override. The README documents the midpoints for Gemini 2.5 Pro. |
+| Agent prompt change for `walkthrough` / `risk_verdict` / `test_coverage` causes regressions on deployed agents | Python fallback (§4.3) synthesizes the same fields when the agent omits them. Backward compat preserved by empty defaults. |
+| Removing `report_usage` breaks the `review_pr` tests that pass it | Test updates are part of this update. |
+| Removing labels breaks users who still apply them | No Gitea API change is needed; the labels just stop being read. A one-paragraph README note acknowledges the change. |
+
+## 9. Prioritized implementation list
+
+| # | Item | Section | Effort |
+|---|---|---|---|
+| P0 | Label removal + repo opt-in (`enabled` in `.pr-review.json`) | §1 | M |
+| P1 | `fmt_tokens()` helper + apply in usage + inline | §2 | S |
+| P1 | Multi-provider cost table (extend `PRICES`, render table, `compare_against`) | §3 | M |
+| P2 | Richer summary (`walkthrough` / `risk_verdict` / `test_coverage`) schema + Python fallback | §4 | L |
+| P2 | `trivial` + `info` severity levels | §6.2 | S |
+| P3 | Merge confidence 1–5 in review header | §6.1 | S |
+| P3 | README + `pilot/README-webhook.md` rewrite | §1, §10 | S |
+| P3 | Test updates across all sections | (each) | M |
+
+P0 first because it changes webhook behavior (must land with the repo-opt-in
+docs so onboarding isn't broken mid-rollout). P1 items are independent and
+small — ship together. P2 ships the user-visible summary improvement.

+# pragent pilot — central dashboard service
+
+A read-only overview + per-repo / per-PR drilldown over the same SQLite
+feedback DB the webhook writes, plus a small form to mutate `.pr-review.json`
+on a covered repo via the Gitea contents API. Companion to the
+[webhook service](README-webhook.md); reuses the webhook image
+(`pragent-webhook:dashboard`) — the pilot modules are baked into `/app/pilot/`,
+and the dashboard is just `python3 -m pilot.dashboard`.
+
+## Architecture
+
+```

+   ▼
+Caddy (TLS, wildcard cert via Cloudflare DNS-01)
+   │   https://pragent-dashboard.marcospaulo.dev.br → 100.74.17.70:31541

+   │
+   │   oauth2-proxy fronts the dashboard, enforces Logto SSO + email allowlist

+   │
+   ├── read /data/feedback.db           (PVC pragent-feedback-data, RO)
+   ├── GET  .../repos/{o}/{r}/...        (Gitea contents API, bot token)
+   └── PUT  .../repos/{o}/{r}/contents/.pr-review.json
+            (edit form submit; Gitea commits a new sha)
+```
+
+Fail-soft. Nothing is ever written to local disk by the dashboard — the
+SQLite file is read-only and `.pr-review.json` mutations go through Gitea's
+contents API so the commit history records who changed what.
+
+The dashboard `Service` is **ClusterIP** — only oauth2-proxy can reach it.
+Public access is gated by Caddy (TLS termination) → oauth2-proxy (Logto SSO
+ allowlist) → dashboard.
+
+## What it does
+
+- **Overview** (`GET /`): summary stats across all onboarded repos — total
+  reviews, distinct PRs, finding counts by severity, false-positive /
+  accepted-pattern scores (see "Feedback loop" in README-webhook.md), and a
+  sparkline of review activity.
+- **Repo drilldown** (`GET /r/<owner>/<name>`): per-repo PRs with their
+  last-review status, finding counts, and links to PR-level drilldowns.
+- **PR drilldown** (`GET /r/<owner>/<name>/<index>`): the bot's review(s)
+  on that PR, inline findings, and reaction / resolved status harvested
+  by `feedback_harvest.py`.
+- **Raw review** (`GET /r/<owner>/<name>/<index>/raw`): the markdown body
+  of the most recent review, for copy-paste / diff-with-prose workflows.
+- **Edit form** (`POST /r/<owner>/<name>/edit`): a small HTML page that
+  loads the current `.pr-review.json` from the repo's default branch and
+  lets the operator edit the JSON (validated, then PUT to Gitea contents
+  API). This is how repo-local `focus` / `instructions` /
+  `reviewers` / `severity_threshold` get tuned per-repo after seeing
+  the feedback roll-up.
+
+All routes return HTML (or plain text for `/raw`) with the same stylesheet
+(`/static/style.css`).
+

+
+Auth is enforced by oauth2-proxy upstream; the dashboard itself only
+checks the `X-Forwarded-User` header that oauth2-proxy sets after a
+successful Logto login + email allowlist match.
+
+There is no `/health` route — don't add one to the k8s probes without
+updating `pilot/dashboard.py` (the handler returns 404 on unknown paths,
+so a probe would loop forever).
+
+## Mutations flow through Gitea, not local fs
+
+The edit endpoint reads the current `.pr-review.json` from
+`GET /repos/{o}/{r}/contents/.pr-review.json?ref=<default-branch>`, lets
+the operator edit it in a form (validated as JSON, length-capped per
+field, no schema migration), and PUTs the new content back via the
+contents API with a commit message like
+`pragent dashboard: update .pr-review.json`. Every edit is a real Gitea
+commit on the default branch, attributable to `pragent-bot`, and the
+next webhook fire picks up the new config — no Pod restart, no image
+rebuild, no pod-level state.
+
+The `/data` mount is **read-only** (see the `readOnly: true` on the
+volumeMount in `~/k8s/pragent-dashboard.yaml`): the dashboard never
+writes the SQLite file, only the webhook + the daily cronjob do, and
+keeping it RO means a buggy deploy can't corrupt the harvested feedback.
+
+## Auth (Logto SSO via oauth2-proxy)
+
+Authentication is delegated to oauth2-proxy, which fronts the dashboard
+in-cluster. The dashboard never sees a cookie or a token — it only
+inspects `X-Forwarded-User` (set by oauth2-proxy after a successful
+Logto login + email allowlist match). Missing header → 401 with
+`WWW-Authenticate: Basic realm="pragent-dashboard"`, which lets
+oauth2-proxy intercept and bounce the browser to Logto.
+
+Email allowlist lives in the ConfigMap `oauth2-proxy-dashboard-emails`
+in namespace `pragent`:
+
+```yaml
+data:
+  authenticated-emails: |
+    marcos.paulodasilva.mp@gmail.com
+    thiago@marcospaulo.dev.br
+```
+
+Edit the ConfigMap to add/remove users; oauth2-proxy hot-reloads the
+file (it logs `watching ... for updates`), no restart needed. This is
+the same isolation pattern as the minecraft-sso / code-server
+allowlists — see `~/.claude/memory/minecraft-sso.md`.
+
+The Logto app is `pragent-dashboard` (tenant `default`, type
+`Traditional`), created by direct INSERT into Logto Postgres mirroring
+the proven `minecraft-sso` pattern. Credentials live in
+`~/k8s/oauth2-proxy-dashboard-secret.yaml` (mode 600, NOT in git).
+
+Public URL: **https://pragent-dashboard.marcospaulo.dev.br** (Caddy
+TLS termination via wildcard cert → Tailscale → NodePort 31541 →
+oauth2-proxy → dashboard ClusterIP).
+
+### Emergency bypass (cookie)
+
+If Logto goes down and you need to access the dashboard before the
+oauth2-proxy restart dance (see `~/.claude/memory/logto-fix.md`),
+`pilot/dashboard.py` can be patched to accept a fallback cookie by
+re-adding the `PRAGENT_DASHBOARD_TOKEN` env path — the route gate is
+isolated in `_is_authed` and the logic is straightforward. The current
+commit intentionally has no bypass because Logto SSO is the single
+source of truth for "who can touch `.pr-review.json`".
+
+## Deploy
+
+The dashboard shares the webhook image, so there's nothing to rebuild
+beyond what the webhook already does. After editing `pilot/dashboard.py`
+or `pilot/dashboard_data.py`, redo the webhook image rebuild + containerd
+import (see `README-webhook.md` § "K8s deployment") and roll both
+deployments.
+
+```bash
+K="microk8s kubectl"
+
+# 1. (one-time) create the Logto app + cookie secret + oauth2-proxy
+#    See ~/.claude/memory/minecraft-sso.md for the SQL INSERT recipe
+#    and ~/k8s/oauth2-proxy-dashboard*.yaml for the manifests.
+
+# 2. apply all pragent-dashboard manifests (dashboard + oauth2-proxy)
+$K apply -f ~/k8s/oauth2-proxy-dashboard.yaml
+$K apply -f ~/k8s/pragent-dashboard.yaml
+
+# 3. roll on image / code changes
+$K -n pragent rollout restart deploy/pragent-dashboard
+$K -n pragent rollout status  deploy/pragent-dashboard --timeout=120s
+$K -n pragent logs -f deploy/pragent-dashboard
+```
+
+K8s manifests:
+
+- `~/k8s/pragent-dashboard.yaml` — Deployment + ClusterIP Service.
+  - `image: pragent-webhook:dashboard` + `imagePullPolicy: Never` —
+    local containerd only, same image as the webhook.
+  - `nodeSelector: kubernetes.io/hostname: kubernets` — pinned to the
+    node holding the `/data` PVC.
+  - `securityContext: runAsNonRoot: true, runAsUser: 10001, runAsGroup:
+    10001, fsGroup: 10001` — matches the image's USER directive;
+    fsGroup makes the RO hostpath volume readable.
+  - `volumeMounts.feedback-data.readOnly: true` — dashboard is
+    read-only over `/data`; mutations go through Gitea, not local fs.
+  - No `readinessProbe` / `livenessProbe` — the dashboard has no
+    `/health` route. If you add one to `pilot/dashboard.py`, add a
+    probe here too.
+  - `resources.requests: {cpu: 100m, memory: 256Mi}` /
+    `limits: {cpu: 500m, memory: 512Mi}` — read-heavy + tiny writes,
+    no opencode subprocess fan-out, much smaller than the webhook.
+  - `Service.type: ClusterIP` — only oauth2-proxy can reach it.
+
+- `~/k8s/oauth2-proxy-dashboard.yaml` — Deployment + ConfigMap +
+  NodePort Service (`oauth2-proxy-dashboard`, NodePort 31541,
+  namespace `pragent`). Same shape as the code-server /
+  minecraft-sso oauth2-proxy. NodePort 31541 was chosen because
+  31540 was the old dashboard NodePort and the 30096..30969 media
+  range + 30350-30351 (other oauth2-proxy NodePorts) were taken.
+
+- `~/k8s/oauth2-proxy-dashboard-secret.yaml` — client-id /
+  client-secret / cookie-secret (mode 600, NOT in git).
+
+## Smoke test
+
+```bash
+# 1. anonymous request → 302 redirect to Logto
+curl -I https://pragent-dashboard.marcospaulo.dev.br/
+
+# 2. pod logs
+microk8s kubectl logs -n pragent -l app=oauth2-proxy-dashboard --tail=50
+microk8s kubectl logs -n pragent -l app=pragent-dashboard --tail=50
+
+# 3. in-cluster direct probe (should 401 without X-Forwarded-User)
+microk8s kubectl port-forward -n pragent svc/pragent-dashboard 8181:80 &
+sleep 2
+curl -I http://localhost:8181/                       # expect 401 + WWW-Authenticate: Basic
+curl -I -H "X-Forwarded-User: marcos@example.com" http://localhost:8181/  # expect 200
+kill %1
+```
+
+The HTML returned with a valid `X-Forwarded-User` should contain a
+`<title>` (whatever the dashboard renders) and **never** `Traceback` or
+any Python exception output. A 401 on the unauthenticated GET is the
+expected behaviour — oauth2-proxy catches it and redirects to Logto.
+
+## Threat model / security notes
+
+- **Behind Logto SSO.** Anonymous traffic gets 302 → Logto. Allowed
+  emails (marcos, thiago) reach the dashboard after Logto login; all
+  others see oauth2-proxy's "not authorized" page. Adding a user is a
+  one-line ConfigMap edit; oauth2-proxy hot-reloads the allowlist.
+- **`PRAGENT_BOT_TOKEN` is Gitea Write scoped** to onboarded repos, so
+  a successful auth bypass on the dashboard is Gitea repo write access,
+  not just read. oauth2-proxy's email allowlist is the only
+  authentication factor — there is no second factor. If this becomes a
+  concern, swap oauth2-proxy for an IdP that supports TOTP/WebAuthn
+  and the dashboard needs no further changes (it just reads the
+  forwarded headers).
+- **CSRF on the edit form.** Per-process random secret embedded as a
+  hidden input + double-submit via the `X-Forwarded-User` context. An
+  attacker would need to (a) steal the user's Logto session cookie
+  from oauth2-proxy and (b) read the rendered HTML to harvest the
+  CSRF token. Both have to happen in the same browser.
+- **Read-only `/data` mount.** The dashboard can't corrupt the
+  harvested SQLite file even if it's compromised. The webhook and the
+  daily cronjob are the only writers.
+- **ClusterIP dashboard Service.** Even if a malicious actor discovered
+  the dashboard's container port, they cannot reach it from outside the
+  cluster — only oauth2-proxy can. NetworkPolicy is the cluster
+  default deny.
+- **`uid 10001` + `runAsNonRoot: true`.** No host-level escalation if
+  the dashboard is popped — it has no caps, no `/proc` mounts.
+- **No author-controlled input is `eval`-ed.** The edit form parses the
+  JSON, validates types / lengths, and re-serialises before the Gitea
+  PUT. The review-side hostile-input concerns from `README-webhook.md`
+  § "Threat model" do **not** apply to the dashboard — the dashboard
+  is a read-mostly viewer over already-harvested, already-posted data.
+
+## Known limitations (pilot)
+
+- Logto SSO is the only auth factor — no per-user sessions, no CSRF
+  token tied to a per-user identity (the per-process CSRF secret is
+  global). Adequate for a single-operator dashboard; not adequate for
+  multi-tenant.
+- No `/health` route — if the dashboard process wedges on a Gitea hang,
+  k8s won't restart it. Add a `/health` route to `pilot/dashboard.py`
+  + a probe here before relying on this in production.
+- The overview is a single-process render over a SQLite file that the
+  daily cronjob also writes. A long Gitea hang during a page render can
+  stall the dashboard until the client request times out (30 s). The
+  underlying SQLite reader is read-only and concurrent-safe, so no
+  data corruption — just a slow page.

+# Evaluation — scorers, ground truth, and the dataset
+
+Langfuse already receives one trace per review (`README-langfuse.md`). This is
+the layer on top: numbers attached to those traces that say how the reviewer
+*behaved*, and the beginnings of a ground-truth signal that says whether it was
+*right*.
+
+Those two things are deliberately kept apart, because only one of them exists
+yet.
+
+## What could and could not be built
+
+`feedback.db` has recorded 113 reviews across 4 repos. It has recorded **zero**
+reactions, zero thread resolutions and zero replies. The harvester, the schema
+and the daily analyzer are all working; nobody has ever reacted to a bot
+comment.
+
+That rules out an accuracy metric today. Correctness needs labels, and a
+judge scored against no labels is theatre. So the scorers here measure
+behaviour, which is computable from data already in hand, and a separate
+bridge exists to turn human reactions into scores the moment any arrive.
+
+## The five behavioural scores
+
+Emitted with every review by `eval_scores.py`, folded into the same ingestion
+batch as the trace so they cost no extra request.
+
+| score | type | what a change in it means |
+|---|---|---|
+| `finding_rate` | NUMERIC | Findings posted. 0 is the restraint case — good on clean code, a failure when the run degraded. Only the rate over time separates those. |
+| `severity_info_ratio` | NUMERIC 0–1 | Share of findings the model rated `info`/`trivial`. Rising = the model is hedging rather than committing. `None` when the review was silent: a ratio over an empty set is undefined, and charting it as 0 would read as perfect calibration. |
+| `severity_max` | CATEGORICAL | Highest severity surfaced, `none` when silent. Categorical because "did this ever surface something serious" is the real question, and a mean of severity ranks answers nothing. |
+| `dropped_findings` | NUMERIC | Findings the model emitted that the parser rejected for an unusable `path`/`line`. This is the only score here that measures the model's raw output. |
+| `cost_per_finding` | NUMERIC | Equivalent USD per finding. A cheaper model that finds nothing is not cheaper. |
+
+### Why `dropped_findings` needed a change to the parser
+
+`parse_findings` and `parse_review_output` discard any finding with a missing or
+unusable location. That happens silently, so a model emitting ten findings at
+invalid locations was indistinguishable from a model that found nothing — both
+produce an empty list. `ai_review.last_parse_dropped()` exposes the delta,
+recorded at parse time.
+
+It must be read at parse time specifically: by the time findings reach
+`_emit_langfuse`, `apply_repo_config` has already filtered them by
+`severity_threshold` and `max_findings`, and those drops are the config working
+as intended, not the model misbehaving.
+
+## Ground truth: `feedback_scores.py`
+
+Turns `feedback.db` into two session-level scores, keyed on `"{repo}#{pr}"`
+(which is what `langfuse_trace` already sets as `sessionId`).
+
+| score | meaning |
+|---|---|
+| `review_engagement` | Share of a PR's findings that drew any human reaction, resolution or reply. **Watch this first** — every quality number is vapour until it moves off 0. |
+| `review_acceptance` | Net verdict over engaged findings, −1 to +1. Absent, not 0, when nothing was engaged: zero would claim humans judged the review neutral, when the truth is nobody looked. |
+
+Session-level rather than trace-level because feedback arrives days later
+against a PR, and nothing in `feedback.db` records which re-run of the reviewer
+produced which comment. The session is both the available join and the honest
+granularity.
+
+Score ids are `uuid5(namespace, repo#pr#name)`, so the daily backfill updates
+rather than duplicates.
+
+## The dataset
+
+`pragent-reviews`, one item per PR the reviewer has run on, seeded by
+`eval_bootstrap.py` from `feedback.db`.
+
+`expectedOutput` is **the reviewer's own prior output**, not human-verified
+truth — every item carries `metadata.labelled_by_human: false`. Read it as a
+regression baseline: re-run a candidate model over these PRs and the diff
+against this column is the behaviour change. Promoting an item to real ground
+truth means a human editing it in the dataset view after re-reading the PR.
+
+### Item ids
+
+`{owner}__{repo}__pr{n}`. The obvious `{repo}#{pr}` cannot be used: items are
+routed as `/datasets/{id}/items/{item_id}`, so the `/` in `owner/repo` splits
+into extra path segments and everything after `#` is a fragment the browser
+never sends — the item is created fine by the API and then 404s when opened.
+Session ids elsewhere keep `{repo}#{pr}`; those are never path segments.
+
+### Filterable metadata
+
+The filter bar matches on `metadata` only — not on `input`, and not on the item
+id — so every facet worth slicing on is a flat, primitive key in `metadata`
+even where it duplicates `input`:
+
+| key | why it is there |
+| --- | --- |
+| `repo`, `owner`, `repo_name` | `owner` exists because a filter on the joined `repo` matches one repo, never a whole org |
+| `pr`, `head_sha` | jump from a filtered row back to the actual PR |
+| `finding_count`, `has_findings` | isolate the silent reviews, which are the interesting negatives |
+| `max_severity` | `"none"` rather than absent — an absent key matches no filter |
+| `reviews_run` | how churny the PR was; high values skew per-item averages |
+| `last_reviewed_at` / `_iso` | epoch sorts, ISO reads |
+| `labelled_by_human` | `false` everywhere today; the flag to filter on before trusting any of it |
+
+Nested objects and lists are deliberately absent: the filter bar cannot reach
+into them.
+
+`max_severity` is derived from `feedback.db`, whose `severity` column is
+re-parsed out of the rendered comment by `feedback_harvest._parse_severity` and
+defaults to `INFO` when its regex misses the badge. Trust the `severity_max`
+**score** (read from the model's structured output) over this facet.
+
+## Experiments
+
+`eval_experiment.py` links reviews that already ran into a dataset run, so the
+Experiments tab is populated without re-running anything. Runs are grouped by
+model — the comparison the pilot actually needs is the same PRs under a
+candidate model with `finding_rate` and `cost_per_finding` side by side. A new
+model produces a new run automatically on the next invocation.
+
+One trace per (run, item), the most recent: a PR re-reviewed on every push has
+many traces, and a run is one output per input.
+
+It uses `POST /api/public/dataset-run-items`, which is deprecated in favour of
+the SDK experiment runner and disappears in Langfuse v4. The deprecation notice
+exempts self-hosted v3 from the cutoff date, and this pilot is stdlib-only by
+design. Revisit when this deployment moves to v4.
+
+Coverage is bounded by the dataset, not by the traces: items only exist for PRs
+with a row in `feedback.db`, and a review that posted no comment leaves a trace
+but no row. That is why a run links fewer items than there are traces.
+
+## Evaluators: `eval_judges.py`
+
+Behaviour scores answer "how many, how severe, how much" — computable from data
+already in hand. Two things they cannot answer:
+
+- **Was the finding any good?** Specificity vs. hedge, generic advice vs.
+  fix-it-now advice — the difference between a useful review and one a
+  developer scrolls past.
+- **Did the summary match the findings?** Claiming "no issues" above two
+  criticals, or describing a problem in prose that never became a finding.
+
+These need a judge. `eval_judges.py` registers two `llm_as_judge` evaluators
+against the trace names this project emits (`pr-review`, `opencode-review`)
+and wires a sampling=1 rule per evaluator. Both run on every observation in a
+matching trace; the only observations in those traces are the review itself.
+
+| evaluator | output | what it answers |
+|---|---|---|
+| `finding_actionability` | NUMERIC 0–1 | How specific and fixable is each finding? |
+| `review_self_consistency` | BOOLEAN | Does the summary agree with the findings? |
+
+The judge is a different model from the reviewer (`kimi-k2.7-code` through the
+headroom hub). A model grading its own output agrees with itself for reasons
+that have nothing to do with quality. The judges are also asked only what they
+can answer from the review itself — never whether a finding is correct, since
+that needs the diff the trace does not carry.
+
+### Why the judge goes through `judge-proxy` (port 8802)
+
+The headroom hub in front of local Ollama returns Anthropic-format responses,
+but every `thinking` content block is missing the `signature` field real
+Claude emits. Langfuse's Zod schema requires it; the omission fails the
+evaluator preflight as `Invalid JSON response`. The `judge-proxy` pod sits in
+front of the hub on `100.74.17.70:8802` and patches every thinking block with
+a synthetic signature before forwarding the response. The model is unchanged;
+only the wire shape is fixed.
+
+```bash
+python3 pilot/eval_judges.py --dry-run   # show what would be created
+python3 pilot/eval_judges.py             # create the LLM connection, evaluators, rules
+```
+
+Idempotent: existing evaluators and rules are skipped, not duplicated. The
+connection is upserted on `provider` so re-runs return the same record.
+
+## Running it
+
+```bash
+# once per project: score configs + dataset (+ score historical traces)
+python3 pilot/eval_bootstrap.py --db /data/feedback.db --backfill-traces
+
+# ship feedback verdicts (runs daily from the feedback CronJob)
+python3 pilot/feedback_scores.py --db /data/feedback.db
+
+# link already-traced reviews into a dataset run per model
+python3 pilot/eval_experiment.py --dry-run
+python3 pilot/eval_experiment.py
+```
+
+Both need `LANGFUSE_HOST`, `LANGFUSE_PUBLIC_KEY`, `LANGFUSE_SECRET_KEY`. In
+cluster they come from the `pragent-langfuse` Secret and point at the ClusterIP
+— never the NodePort, whose oauth2-proxy 302s ingestion to Logto and drops it.
+
+## Gotcha: HTTP 207 is not success
+
+The ingestion endpoint answers `207 Multi-Status` when *some* events failed, so
+a batch where **every** event was rejected still returns 207. An early version
+of these scorers omitted the required per-event `timestamp` and silently
+ingested nothing while reporting success. `langfuse_trace._warn_on_rejected_events`
+now logs the per-event errors under `LANGFUSE_DEBUG=1`. If scores are missing,
+check that before anything else.
+
+## What the first run showed
+
+Backfilled over 42 existing traces and 13 PRs:
+
+```
+cost_per_finding     n=42  mean=0.3133  min=0.0880  max=0.9042
+finding_rate         n=42  mean=0.4762  min=0.0000  max=4.0000
+severity_info_ratio  n=14  mean=0.0000
+review_engagement    n=14  mean=0.0000
+severity_max         {none: 28, medium: 11, high: 1, critical: 2}
+```
+
+Two things worth keeping:
+
+- **The reviewer is not info-heavy.** `feedback.db` shows 61 of 62 findings at
+  `INFO`, which looked like a badly calibrated model. It is not: `severity_max`
+  reads `medium`/`high`/`critical` on every trace that found anything, and
+  `severity_info_ratio` is flat 0. The `INFO` in the DB comes from
+  `feedback_harvest._parse_severity`, which defaults to `INFO` when its regex
+  misses the severity badge in the rendered comment. The DB severity is a
+  re-parse artifact; the score reads the model's structured output directly.
+- **28 of 42 reviews found nothing** (67%), and **engagement is flat zero**. The
+  first is not yet interpretable without the second.

+# pragent → Langfuse
+
+Every review the pilot runs ships one **trace** to a self-hosted Langfuse. The
+review body already prints a usage table, but that table lives and dies inside
+one Gitea PR. Langfuse is where the same numbers become a trend: tokens per
+review, latency per model, equivalent cost per repo, and how those move when
+the model or the tiering changes.
+
+## The ollama / claude split
+
+Both paths route through the same headroom proxy, so the provider prefix does
+not distinguish them — `headroom/claude-sonnet-5` is Claude spend,
+`headroom/glm-5.2:cloud` is not. The split is keyed off the **bare model name**
+and lands on the trace's `environment`:
+
+| resolved model              | environment |
+| --------------------------- | ----------- |
+| `headroom/claude-sonnet-5`  | `claude`    |
+| `claude-opus-5`             | `claude`    |
+| `headroom/glm-5.2:cloud`    | `ollama`    |
+| `headroom/MiniMax-M2.7`     | `ollama`    |
+| `vllm-qwen38/qwen3.8-27b`   | `ollama`    |
+
+Langfuse takes an environment selector on every dashboard, filter and cost
+breakdown, so the two spend stories stay separate inside one project — one key
+pair to rotate instead of two. Tags carry the finer cut:
+`provider:headroom`, `model:<bare>`, `engine:opencode`, `repo:<owner/name>`,
+`lens:<id>` per fan-out lens.
+
+To split into two *projects* later, point `LANGFUSE_PUBLIC_KEY` /
+`LANGFUSE_SECRET_KEY` at the second project on whichever deployment runs the
+Claude path. Nothing in the code needs to change.
+
+## What a trace carries
+
+- **trace** `pr-review` — `sessionId` = `owner/repo#index`, so every push to one
+  PR groups together. Input is the PR identity; output is the summary + finding
+  count; metadata carries steps, duration, severity counts and the provider's
+  own reported cost.
+- **generation** `opencode-review` — `model`, `usageDetails`, `costDetails`.
+
+`usageDetails.input` is the **uncached** input. opencode reports `cache_read`
+*inside* `input`, and Langfuse sums the keys it is given, so passing both
+verbatim would bill the resent prefix twice.
+
+### How cost is priced
+
+Langfuse has no price table of its own here — we compute the number and ship it
+as `costDetails.total`, so what Langfuse charts is exactly what
+`cost_model.PRICES` says.
+
+A model that genuinely bills (`claude-*`, `gpt-*`, `gemini-*`, `grok-*`) is
+priced **as itself**: basis `actual`.
+
+A model that costs nothing through the headroom proxy is priced against a
+**comparison target** instead: basis `equivalent:<target>`. That covers the
+models absent from `PRICES` (`MiniMax-M2.7` — which is what the webhook
+actually runs — and `glm-5.2:cloud`) as well as entries priced at all zeros
+(the self-hosted vLLM `qwen3.8-27b`). Without this the dashboard would be a
+flat $0.00 line, since the pilot's own path is free.
+
+The target follows the same precedence as the review body, so the PR and the
+dashboard never disagree:
+

+
+An equivalent cost is a hypothetical, not money spent, so every trace is tagged
+`cost:actual` or `cost:equivalent:<target>` and the generation metadata carries
+`cost_basis`. Filter on it before reading any cost chart as spend.
+
+If the comparison target itself is unknown, the trace ships usage with **no**
+cost block — better no number than a wrong one.
+
+Anthropic prices in `cost_model.PRICES` were fetched 2026-08-18; re-check them
+before quoting anything externally.

+## Configuration
+
+| env                   | meaning                                                   |
+| --------------------- | --------------------------------------------------------- |
+| `LANGFUSE_HOST`       | `http://langfuse-web.langfuse.svc.cluster.local:3000`      |
+| `LANGFUSE_PUBLIC_KEY` | `pk-lf-…`                                                  |
+| `LANGFUSE_SECRET_KEY` | `sk-lf-…`                                                  |
+| `LANGFUSE_TIMEOUT`    | seconds, default `5`                                       |
+| `LANGFUSE_DEBUG`      | `1` to log ingestion failures to stderr                    |
+
+Unset host or either key ⇒ emission is a silent no-op. That is the default, so
+a checkout without Langfuse behaves exactly as before.
+
+## Fail-open
+
+`langfuse_trace` is stdlib-only (`urllib`) and every entry point swallows its
+own exceptions; `_emit_langfuse` in `ai_review.py` wraps even the import. A
+Langfuse outage cannot fail, delay past `LANGFUSE_TIMEOUT`, or alter a review.
+
+Both token-spending exit paths emit — the normal post **and** the salvage path
+where the agent produced unparseable output. That run cost the same as a clean
+one, and is precisely the failure worth trending.
+
+## Deployment
+
+Cluster side lives outside this repo: `~/k8s/langfuse.yaml` (ClickHouse +
+web + worker, reusing the gitea postgres, gitea valkey and minio),
+`~/k8s/oauth2-proxy-langfuse.yaml` (the Logto gate), and
+`~/k8s/langfuse-setup.sh`, which provisions the database, the bucket, the
+secrets, and wires `pragent-webhook` with the three env vars above.
+
+The UI is at **https://langfuse.marcospaulo.dev.br**:
+
+    browser -> Caddy (VPS, TLS, DNS-01) -> tailscale
+            -> 100.74.17.70:30361 -> oauth2-proxy (Logto, email allowlist)
+            -> langfuse-web (ClusterIP)
+
+Logto sits at *both* layers off one app (`langfuse`, two redirect URIs): the
+proxy gates the domain, and Langfuse's own NextAuth uses the same Logto as a
+custom OIDC provider, so the inner login is a silent redirect rather than a
+second password.
+
+pragent does **not** go through any of that. It posts to
+`langfuse-web.langfuse.svc.cluster.local:3000` from inside the cluster, on
+API-key auth — putting ingestion behind an interactive SSO gate would break it
+on the first review.

+"""pragent pilot — dashboard read-only query layer.
+
+Three functions: overview / repo_summary / pr_summary. Each opens the SQLite
+feedback DB via `feedback.init`, runs the queries it needs, and returns plain
+dicts/lists. NEVER writes — that's the dashboard_server's job (via the Gitea
+contents API). This module is what the dashboard_server's templates render.
+
+All three functions are tolerant of a missing or empty DB: they return the
+shaped dict with zeros/empty lists rather than crashing. The dashboard is a
+read-only view; the pilot can boot with no feedback DB and the dashboard
+should still load.
+
+Cost note: `total_cost_usd` is hardcoded to 0.0. Per-review `usage:cost` is
+not in the feedback SQLite — only the raw `review` / `inline_finding` rows
+are stored there. The equivalent-cost calc lives in `ai_review._render_collapsible_usage`
+and only knows about the latest review's tokens. Surfacing a rolled-up dollar
+figure without per-row telemetry would be guessing, so we don't.

+"""pragent pilot — one-time Langfuse project setup for evaluation.
+
+Three jobs, each idempotent so it can be re-run after any change:
+
+  1. **Score configs.** Registers the schema for every score pragent emits
+     (`eval_scores.SCORE_CONFIGS` + `feedback_scores.SCORE_CONFIGS`). Without
+     these the scores still ingest, but nothing stops a later scorer writing
+     `severity_max="HIGH"` beside today's `"high"` and quietly splitting one
+     series into two. Configs are immutable in Langfuse — a name that already
+     exists is left alone rather than updated.
+
+  2. **Dataset.** Seeds `pragent-reviews` from `feedback.db`: one item per PR
+     the reviewer has actually run on, carrying the repo/PR/sha as input and
+     the findings it posted as `expectedOutput`.
+
+     Read `expectedOutput` here as "what the reviewer said last time", not "what
+     is correct" — no human has labelled any of it. It is a regression baseline:
+     re-run a candidate model over these PRs and the diff against this column is
+     the behaviour change. Promoting an item to real ground truth means a human
+     editing it after reviewing the PR, which is what the dataset view is for.
+
+  3. **Trace backfill** (`--backfill-traces`). Scores only ride along with new
+     reviews, so without this the charts stay empty until the next PR lands.
+     Every trace `langfuse_trace` has ever written already carries the finding
+     count, the severity histogram and the cost in its metadata, which is
+     everything four of the five scorers need. `dropped_findings` is absent from
+     historical traces and is left unscored rather than backfilled as zero.
+
+  4. **Reports** what it found, so the gap between "reviews recorded" and
+     "reviews with human feedback" is visible rather than assumed.

+
+An "experiment" in Langfuse is a dataset run: a set of (dataset item, trace)
+links under one run name. The Experiments tab then shows one row per item with
+its scores, and lets two runs be diffed side by side.
+
+Nothing here re-runs the reviewer. Every PR in `pragent-reviews` has already
+been reviewed, and each of those reviews left a trace carrying its findings,
+cost and scores. This links what exists, which is what makes the tab useful on
+day one instead of after the next N pushes.
+
+Runs are grouped by **model** by default, because that is the comparison the
+pilot actually needs to make: the same PRs reviewed by MiniMax vs whatever
+replaces it, with `finding_rate` and `cost_per_finding` side by side. Group by
+`none` for a single "all traces" run.
+
+One trace per (run, item) — the most recent. A PR re-reviewed on every push has
+many traces, and a dataset run is defined as one output per input; feeding it
+the other five would make the per-run averages meaningless.
+
+Note on the endpoint: `POST /api/public/dataset-run-items` is deprecated in
+favour of the SDK experiment runner / OTel ingestion, and disappears in
+Langfuse v4. This instance is self-hosted v3, which the deprecation notice

+"""pragent pilot — LLM-as-a-judge evaluators for the reviewer.
+
+The deterministic scorers in `eval_scores.py` measure *behaviour*: how many
+findings, how severe, how much they cost. None of them can say whether a
+finding was any good. With no human labels in `feedback.db`, a judge is the
+only thing that can — so these two ask the questions that need no ground truth,
+only the review itself:
+
+  `finding_actionability` — is each finding concrete enough to act on? A
+    reviewer that says "consider improving error handling" at file level is
+    indistinguishable from a useful one by finding count alone. This is the
+    failure mode a cheap model degrades into first.
+
+  `review_self_consistency` — does the summary agree with the findings it
+    posted? Claiming "no issues found" above a list of two criticals, or
+    describing a problem in prose that never became a finding, is a defect the
+    reviewer can commit entirely on its own.
+
+Neither judge is asked whether a finding is *correct*. That needs the diff,
+which these traces do not carry, and a judge asked to rule on correctness from
+a summary alone will confabulate. Accuracy stays an open question until humans
+start labelling — which is what `feedback_scores.py` is there to capture.
+
+**The judge is a different model from the reviewer.** The reviewer runs
+MiniMax-M2.7; the judge runs kimi-k2.7-code through the same headroom hub. A
+model grading its own output agrees with itself for reasons that have nothing
+to do with quality.
+
+Evaluators score *observations*, and their variable mapping reads the
+observation's own input/output — which is why `langfuse_trace` now writes the
+review onto the generation and not just onto the trace.

+Four numbers computed from a review that already happened, shipped to Langfuse
+as scores on the review's trace. All are derived from data the reviewer already
+has in hand: no LLM judge, no ground truth, no extra token spend.
+
+Why these four and not `helpfulness`/`quality`
+----------------------------------------------
+They come from what the recorded reviews actually did, not from a generic eval
+checklist:
+
+  * `severity_info_ratio` — of the findings ever posted to a PR, effectively all
+    landed at `info`. Either the model will not commit to a severity or the
+    per-repo `severity_threshold` is filtering the rest out. Trending the ratio
+    per model says which.
+  * `finding_rate` — most reviews post nothing at all. Silence on clean code is
+    the goal; silence because the run degraded is a failure. Same output, two
+    causes, and only the rate over time separates them.
+  * `dropped_findings` — `ai_review.parse_findings` discards any finding whose
+    `path`/`line` is unusable. That happens silently, so a model that emits ten

+that produces suggested addenda for `.pr-review.json:instructions` and
+`PRAGENT_ADDITIONAL_CONTEXT_URL` (see `feedback_analyze.py`).
+
+Why SQLite: stdlib, no extra deps in the container, single writer (the
+webhook server is one process per pod). Mount at `/data/feedback.db`
+via the `feedback-data` PVC.
+
+Schema (idempotent — safe to call `init` at every boot):

+    review(repo, pr, head_sha, body_comment_id, posted_at, review_id_gitea)
+    inline_finding(review_id → review.id, repo, pr, path, line,

+It survives across reviews of the same finding on the same line — same
+finding on PR #5 and PR #12 of the same file de-duplicate, so the daily
+analyzer can count votes across reviews instead of one-at-a-time.
+
+Everything is best-effort. The webhook server never aborts a review

+"""pragent pilot — daily feedback analyzer.
+
+Reads `feedback.db` (written by `feedback_harvest.py`) and produces a
+markdown report that:
+
+  1. Ranks inline findings by **net false-positive score** (downvotes +
+     unresolved + negation-phrase replies − upvotes − resolved). Top of
+     this list = "the bot has been wrong about this repeatedly". These
+     are the candidates that *might* belong in the per-repo
+     `.pr-review.json:instructions` addendum.
+  2. Ranks findings by **net acceptance** — repeated 👍 / resolution =
+     "the bot's framing here is genuinely useful". These can be promoted
+     to the shared `architecture.md` so they don't have to be re-derived
+     every PR.
+  3. Reports a **restraint metric** — for every PR where the bot posted
+     zero findings, count how often a human reviewer also posted zero
+     substantive review comments. When the bot is loud on clean code,
+     that's a false-positive rate we can act on (DoorDash lesson:
+     "excessive noise on clean code is its own failure mode").
+  4. Reports a **case-review queue** — every disagreement case (a
+     downvote, unresolved, or a reply matching `FALSE_POSITIVE_PHRASES`)
+     is listed in full so a human can re-read the original PR and decide
+     if the finding was right or wrong.
+
+Output is plain markdown so it can be posted as a Gitea issue / comment
+without rendering work. Designed to be reviewed by a human, not auto-
+applied — per the DoorDash pattern, every material change to model /
+prompt / context goes through a benchmark gate first; this report IS
+that gate (or, more precisely, the queue feeding the gate).
+
+Never raises. A bad DB / no data → returns a friendly empty-state report.

+"""pragent pilot — feedback harvester.
+
+For each PR the webhook server is about to review, walk back through the
+Gitea-side state of every bot comment from every prior review on that PR
+and record:
+  - reactions on the review body + on each inline comment
+  - thread-resolved state (Gitea's `resolver` field; non-empty = resolved)
+  - replies (issue-comments with `review_comment_id` matching ours)
+  - the bot's own findings_count + inline_count per review (for the
+    restraint metric)
+
+Everything is best-effort. A single 404 or 5xx is logged and skipped — we
+must never abort a review because the feedback DB had a hiccup.
+
+The harvester is intentionally separate from `review_pr` so it can be
+called independently (e.g. by the daily analyzer's "backfill" mode) and
+tested in isolation against a mocked Gitea client.

+"""pragent pilot — feedback DB to Langfuse scores.
+
+`feedback.db` already records every reaction, thread resolution and reply a
+maintainer leaves on a bot comment. That is the only ground truth pragent has
+about whether a finding was any good, and until now it went to a markdown report
+nobody reads and nowhere else. This ships it to Langfuse as session-level
+scores, so "was the reviewer right" sits on the same axis as "what did it cost".
+
+Session, not trace
+------------------
+`langfuse_trace` sets `sessionId` to `"{repo}#{pr}"` and lets the trace id be a
+fresh uuid per review. Feedback arrives days later against a PR, not against one
+particular re-run of the reviewer, and nothing in `feedback.db` records which
+trace produced which comment. Scoring the session is therefore both the
+available join and the honest granularity: this is feedback on the review of
+this PR, not on one invocation.
+
+Two scores, deliberately separated
+----------------------------------
+  * `review_engagement` — the share of a PR's findings that got any human
+    response at all. This is a signal about the *feedback loop*, not the
+    reviewer: at the time of writing it is 0.0 across all 113 recorded reviews,
+    which is exactly the fact that makes an accuracy metric impossible today.
+    It must be watched first, because every other quality number is vapour
+    until it moves.
+  * `review_acceptance` — net verdict over the findings that *did* get a
+    response: (upvotes + resolved) - (downvotes + negation replies), normalised
+    to -1..1. Computed only over engaged findings, so an ignored review scores
+    `None` rather than 0. Zero would read as "humans judged this exactly
+    neutral"; the truth is nobody looked.
+
+Fail-open and idempotent. Score ids are derived from (repo, pr, name) so a
+re-run overwrites rather than duplicates.

+"""pragent pilot — Langfuse trace emission.
+
+Ships one trace per PR review to a self-hosted Langfuse (v3) so the reviewer's
+token spend, latency and per-model behaviour are queryable outside the review
+body. The review body already renders a usage table; that table is per-PR and
+disappears into Gitea. This is the same numbers, aggregated.
+
+Why hand-rolled instead of the `langfuse` SDK: the pilot image is stdlib-only
+(see pilot/Dockerfile — no requirements.txt anywhere in the repo), and the
+ingestion API is a single authenticated POST of a JSON batch. Pulling an SDK
+plus its otel dependency tree into a fail-open telemetry side-path is a bad
+trade.
+
+Provider split
+--------------
+`environment` on every trace is either `ollama` or `claude`, derived from the
+resolved display model (`resolve_environment`). That is what keeps the two
+spend stories separate in Langfuse: every dashboard, filter and cost breakdown
+takes an environment selector, so "what did the local/self-hosted path cost"
+and "what did the Claude path cost" are two views of one project rather than
+two projects with two key pairs to rotate. Tags carry the finer split
+(`provider:headroom`, `model:...`, `engine:opencode`).
+
+Cost
+----
+The pilot's own path bills $0 (headroom proxy, no per-token charge), so the
+`cost` reported to Langfuse is the *equivalent* cost from `cost_model` — what
+the same tokens would bill on the comparison model. That is the number worth
+trending; a chart of $0.00 is not.
+
+A model is "free" when `cost_model.PRICES` has no entry for it (MiniMax-M2.7,
+glm-5.2:cloud) or when its entry is all zeros (the self-hosted vLLM qwen). In
+both cases the reported cost is priced against the comparison target instead —
+same precedence the review body uses: `.pr-review.json:cost_target` >
+`PRAGENT_PRICE_TARGET` > `claude-sonnet-5`. A paid model is priced as itself.
+
+Because a hypothetical and a real charge must never be read as the same
+number, every trace is tagged `cost:actual` or `cost:equivalent:<target>`, and
+the generation's metadata carries `cost_basis`.
+
+Fail-open: every entry point swallows its own exceptions. Telemetry must never
+cost a review.
