Marcos 2b1cf750b7 fix(review): correct diff-compression line numbers, prior-review dedupe, triage skip
Four defects, all found reviewing PR #9 (two of them by pragent-bot's own
review of that PR, which the anchoring bug then misplaced):

* compress_diff dropped context lines but copied the original `@@` hunk
  header verbatim, so the header no longer described the lines beneath it.
  parse_diff_anchors then walked stale headers and produced anchor sets
  shifted by the number of elided lines, misplacing inline comments or
  demoting them to bullets. Each surviving run of lines is now re-emitted as
  its own hunk with a recomputed `@@ -a,b +c,d @@`, so the output stays a
  valid unified diff whose numbers describe the real post-change file. The
  pseudo-marker `@@ … N context line(s) omitted … @@` is gone; it parsed as
  a hunk header and reset the anchor counter to 0. Anchoring additionally
  runs on the raw diff now, so the prompt window can never shrink the
  anchorable set.

* compress_diff's `_FILE_HEADER` regex matched diff *body* lines: a removed
  YAML `---` separator or an added `++` line was read as a file header,
  truncating the hunk and dropping its `@@` header with it. Body detection
  is now prefix-based, with a full-shape hunk-header regex.

* extract_finding_bullets could not match the bullets pragent itself posts:
  summary_bullets renders an emoji severity badge between the `-` and the
  `[SEV]` tag, which the regex rejected, so compact_prior_reviews always
  returned [] and every re-review repeated its previous findings.

* triage returning `{"lenses":[]}` — documented in .opencode/agents/triage.md
  as "no lens has surface, skip the fan-out" — ran every lens instead, since
  _intersect_with_triage mapped an empty selection to "all" and the call site
  had a second `or reviewers` fallback. `[]` and None are now distinct
  outcomes: `[]` skips, None fails open. A roster naming only unknown lens
  ids now fails open rather than silencing the review. The skip path returns
  a well-formed empty-findings response instead of "", which had landed in
  ai_review's unparseable-output branch and posted "AI review produced no
  parseable output" — a malfunction message for a normal verdict.

Also: non-URL references (a CVE id, a doc title) rendered as
`[CVE-2024-1234](CVE-2024-1234)`, a broken relative link in Gitea — now
plain text. PRAGENT_DIFF_CONTEXT and friends parse through _int_env, so a
typo logs and falls back instead of killing a review mid-flight. Removed
format_usage_section, dead since the collapsible usage block replaced it and
carrying a duplicate copy of the price-target logic.

Tests: 290 -> 301. New coverage for hunk-header fidelity before/after
compression, header-shaped content lines, the bullet round-trip against the
real renderer, and triage's three outcomes (previously untested).

pragent-bot 78bcf6a9a0 feat(review): multi-lens orchestration — 5 parallel opencode subprocesses (security/docs/code-quality/tests/perf)
On by default, opt-out via "reviewers": []. 290 tests pass.

- pilot/opencode_review.py: ReviewerSpec dataclass, default_reviewers(),
  parse_reviewers_config(), parse_triage_config(), resolve_reviewers(),
  _normalize_lens_finding(), posthash() (matches feedback.py scheme),
  _agreement_hash() (severity-free for cross-lens promotion), _tone_strip(),
  synthesize() 7-stage (severity_floor → tone-strip → length cap → per-lens
  max → per-file cap → dedup by _posthash → cross-lens severity promote →
  per-PR cap), run_lenses() (ThreadPoolExecutor pool=4), triage(),
  _intersect_with_triage(), _filter_by_skip_if(), run_lenses_review().
  run() routes to fan-out when config.reviewers[] present or PRAGENT_REVIEWERS=1.
- pilot/ai_review.py: parse_repo_config learns reviewers[] and triage objects
  (id regex /^[a-z0-9][a-z0-9-]{0,31}$/, 8-entry cap, agent_file/model/
  severity_floor/max_findings/activation/skip_if_all_changed_paths/hotpath_globs).
  review_pr branches to opencode_review.run_lenses_review when configured.
  _render_collapsible_usage shows lenses: ... line when present.
- .opencode/agents/{docs,code-quality,triage}.md: 3 new lens subagents.
- .opencode/skills/lens-orchestration/SKILL.md: strict-JSON contract every
  lens subagent MUST honor.
- .opencode/agents/pragent.md: slim to coordinator; no more hardcoded
  @security/@tests/@perf delegation; loads lens-orchestration skill.
- .opencode/README.md: rewrite 'Add a review lens' recipe for multi-lens.
- pilot/README-webhook.md: new 'Multi-lens pipeline' section (diagram +
  default roster + config schema + env vars + cross-lens dedup contract).
- tests: 36 new tests (test_ai_review.py +12 reviewers/triage/usage,
  test_opencode_review.py +24 orchestration). posthash golden-vector matches
  feedback.py exactly across 5 severity × 2 line cases.

Marcos e8ebc54362 feat(review): ADDITIONAL_CONTEXT_URL — repo-provided static context cached per review
Long agent loops re-send the brief prefix on every step; cheap reusable
knowledge (architecture summary, module map, conventions, glossary) belongs
in a versioned file the maintainers control so the agent doesn't re-derive
it from the source tree on every PR. Two wiring paths, merged (env first):

* env var PRAGENT_ADDITIONAL_CONTEXT_URL — comma-separated, deployment-wide
* .pr-review.json:additional_context_urls — list[str], read from the PR's
  base branch (same trust boundary as the rest of the file)

Implementation:
* _parse_additional_context_env splits/dedupes/trims.
* _resolve_additional_context_urls(config) merges env (first) + config
  (then, skipping env-dupes); caps at 8.
* fetch_additional_context(urls) fetches each URL with urllib (5s timeout,
  http/https only — file://, javascript:, ftp:// rejected defensively),
  caches by URL in a module-level dict for the pod lifetime, truncates
  per-URL to 4k chars + total to 16k chars, best-effort (network errors
  are logged and skipped — never aborts the review).
* Result injected into build_user_prompt under "## Repo-provided context"
  between repo config and prior reviews. In the opencode engine it lands
  in .pragent/brief.md under its own section. The brief explicitly labels
  each block's CONTENT as untrusted (same as PR description) — section
  heading is trustworthy, body isn't.
* parse_repo_config accepts the field, caps at 8 entries, drops
  non-strings and empty strings.

Docs: pilot/README-webhook.md "Repo-provided static context" section —
env var + JSON example + Nexus raw-hosted recipe.

Tests: 14 new (208 total), covering env merging + dedup, scheme rejection,
per-URL cap, total cap, caching by URL, brief injection. All mock urllib
with a context-manager stand-in (no real network).

Marcos ec26ec000a feat(review): equivalent provider price + enriched .pr-review.json schema
Three things in this commit, all in the review-rendering path:

1. COST DISPLAY — the `## 🔋 AI usage` section used to show $0.00 because
   the pilot runs on headroom/glm-5.2:cloud at no per-token charge. Now it
   shows TWO lines: the equivalent provider cost (default Claude Sonnet 5;
   configurable via .pr-review.json:cost_target or PRAGENT_PRICE_TARGET env)
   AND the actual $0.00 line. Maintainers can now budget on what the same
   measured tokens would cost on a paid model.

   equivalent_cost() builds a cost_model.Usage from the measured dict and
   runs cost_model.cost() against the resolved provider. _resolve_price_target
   walks repo config > env > default, surfaces typos as an inline note on
   the usage line (not a crash).

2. .pr-review.json SCHEMA — seven new optional fields:
     style                strict|balanced|lenient  (default: balanced)
     severity_threshold   low|medium|high|critical (per style)
     max_findings         1..30                     (per style)
     exclude_tests        bool                      (skip test files)
     require_tests        bool                      (synthetic finding)
     patterns             {allow: [...], deny: [...]} (glob filter)
     cost_target          <PRICES key>              (see #1)

   The first three are style-driven defaults — strict = 5 findings / high+,
   balanced = 12 / medium+, lenient = 15 / low+. Override per-field.
   patterns globs support * and **; built-in fnmatch-style with re.escape.

3. APPLY CONFIG — findings are filtered by the new schema before being
   split into anchored/unanchored. apply_repo_config() drops by exclude_tests
   / exclude_paths / patterns.deny / patterns.allow / severity_threshold, then
   caps at max_findings. require_tests=true appends a synthetic 'low' finding
   when changed paths include non-test files but no test file changed
   alongside them.

   build_user_prompt renders the new fields into the brief so the agent knows
   about style / threshold / patterns explicitly (not just via instructions).

Plus plumbing:
  * review_pr runs compress_diff(diff, context=PRAGENT_DIFF_CONTEXT) before
    handing the diff to either engine. Default context=1 (enough to anchor;
    full files are on disk in the workdir anyway). -1 disables.
  * compact_prior_reviews(prior) keeps only finding-bullet lines, drops the
    rest. Prior-review cap lowered 8k -> 4k chars in build_user_prompt.
  * opencode_review.write_brief accepts compression_note (rendered under
    the PR description, OUTSIDE the untrusted-data fence).

160 new tests covering equivalent_cost (4), format_usage_section cost lines
(5), parse_repo_config extended schema (6), apply_repo_config filters (8),
effective_config style defaults (2), compact_prior_reviews (2), and the
whole diff_compress suite (14 from the previous commit). 174 pass / 0 fail.

Marcos f59b906395 chore: scrub private infrastructure for a public repo, rewrite README
Audited the working tree and all 26 commits of history for credentials: none
found. No API keys, no private keys, no tokens — the live bot token, webhook
secret and admin token appear nowhere in the repo or its history.

What was there was infrastructure disclosure, which is recon material rather
than a leak, but has no business in a public repo:

- Tailnet addresses and cluster-internal hostnames in code, docs and the CI
  template. The model endpoint is now supplied at runtime via
  PRAGENT_MODEL_BASE_URL and patched into opencode.json by install_config();
  the committed config carries a placeholder, guarded by a test.
- A host path (/home/marcos) as the default rtk directory — now unset.
- Real usernames in the onboarding docs — now alice/acme.
- A standing list of one-time setup tokens that were never revoked, named
  individually. Removed. Note that removing the list does not revoke the
  tokens: they should still be revoked in the Gitea admin UI.

The substitution happens in Python rather than via opencode's {env:VAR} config
templating, because the reviewer subprocess runs with an allow-listed
environment — resolving it before the process starts keeps that allow-list from
having to grow.

README rewritten for a reader who has never seen the project: what it does and
what that output looks like, honest status (pilot works, framework designed but
unbuilt), the security model up front given what this thing is, and the measured
cost numbers including the two effects that make naive estimates wrong.

History still contains the old addresses. They are tailnet-only and not
credentials, so no rewrite.

Tests: 131 -> 137.

Marcos 8c491a7626 harden(pilot): contain hostile PR content, bound the webhook, fix anchoring
The reviewer runs an opencode agent with `bash: "*": allow` over a checkout of
the PR author's branch, and the pod holds a Gitea Write credential. Those two
facts had no wall between them.

Security
- _build_env now allow-lists the subprocess environment instead of inheriting
  it, so PRAGENT_BOT_TOKEN and WEBHOOK_SECRET never reach the agent. This was
  the live hole: a PR body or an AGENTS.md could ask the agent to `curl` the
  token out, and it had both the value and the tool.
- sanitize_workdir deletes author-controlled agent-instruction files from the
  checkout before opencode starts (AGENTS.md at any depth, CLAUDE.md,
  .cursorrules, a repo opencode.json/.opencode, copilot-instructions.md).
  opencode loads nested AGENTS.md as instructions, so a PR could otherwise ship
  its own system prompt. They are still reviewed, as data.
- The brief fences PR title/body and diff in --- UNTRUSTED --- markers under a
  trust-boundary preamble; the pragent agent, the three lens subagents and the
  review-methodology skill now treat injection attempts as a critical finding
  to report rather than an instruction to obey.
- .pr-review.json is read from the PR's base branch, not the head sha. Its
  `instructions` field is spliced into the reviewer's prompt, so head-ref
  reading let any author rewrite the reviewer's rules. Fields are length-capped.
- Untar rejects escaping symlinks, parent traversal, and writes through a
  planted symlink (tar-slip).
- The image runs as uid 10001 instead of root.

Robustness
- Bounded review concurrency (PRAGENT_MAX_CONCURRENT_REVIEWS, default 2). Each
  review forks an opencode process; a thread per delivery was a fork bomb on a
  burst of labels or Gitea retries.
- An in-flight (repo, index, sha) claim closes the check-then-act race in the
  sha-marker dedupe, where two deliveries a second apart both read "not yet
  reviewed" and both posted.
- Request bodies are capped before being read into memory.

Correctness
- parse_diff_anchors counts a whitespace-stripped blank context line. Skipping
  it desynced the new-line counter for the rest of the hunk and silently
  misplaced every later inline comment in that file.
- post_inline_review's body-only fallback folds the anchored findings into the
  body. It previously posted a summary saying "N inline comment(s) below" with
  no comments and no findings — losing them all on the one path that matters.
- fetch_pr_diff's files-endpoint fallback emits real a// b/ prefixes (so
  changed_files and the anchor parser work on it) and reports both HTTP statuses
  in its error instead of the same one twice.
- The CI workflow template pins PRAGENT_ENGINE=ollama; review_pr defaults to
  opencode, which does not exist on a Gitea Actions runner.

Tests: 68 -> 101, covering each of the above.

Marcos 087834565d feat(pilot): token-usage reporting gated by AI-USAGE label
Add per-review + per-comment token accounting, surfaced only when a PR carries
the new AI-USAGE label (on top of the existing AI-REVIEW trigger).

opencode_review:
- run_opencode now uses `--format json`; parse_opencode_events reconstructs the
  assistant text from `text` events and sums tokens/cost/steps from every
  `step_finish` event (tolerant of noise / missing fields).
- run() measures duration_s around the opencode call and returns (text, usage).
- changed_files(diff) extracts the `+++ b/` paths; the brief now lists them
  under a "Changed files" focus block so the agent grounds findings in the
  diff's neighbourhood instead of unbounded whole-repo walks.

ai_review:
- format_usage_section renders a `## AI usage` block: measured totals
  (in/out/reasoning/cache/cost/steps/duration), the whole-repo scope note, and
  an attributed per-finding table. Per-comment counts are output tokens split by
  each finding's body weight — labelled "attributed" since one model pass
  produces all findings.
- inline_comment_body appends `🪙 ~N tok (X% · attributed output)` when
  attribution is present.
- review_pr gains report_usage; compute_attribution stashes _tok_attrib/_tok_pct.
- format_review_body inserts the usage section between summary and findings.

webhook_server:
- Fire on every pull_request action except `closed` (denylist, was an allowlist)
  — the AI-REVIEW gate + sha dedupe keep this safe.
- AI-USAGE label detection + PRAGENT_USAGE_ALWAYS env drive report_usage.

.opencode factory + review-methodology skill: new "Ground findings in context"
step — read callers/imports/sibling functions per changed file (1-3 files per
finding), no unbounded walks.

Tests: parse_opencode_events (text+usage sum, malformed tolerance, none-usage),
changed_files, compute_attribution math, inline 🪙 line, format_usage_section
totals/table/cost, format_review_body ordering. 68 passing.

Marcos c7c6c3edd2 fix(opencode): resolve /usr/local/bin -> /usr/bin opencode path in pod
The npm prefix in the Dockerfile is /usr, so opencode installs to
/usr/bin/opencode (symlink to /usr/lib/node_modules/...), not
/usr/local/bin/opencode. The cluster E2E failed with ENOENT on
/usr/local/bin/opencode. Fix in three places:
- Dockerfile ENV PRAGENT_OPENCODE_BIN=/usr/bin/opencode
- ~/k8s/pragent-webhook.yaml env value
- _opencode_bin() now defensive: if the configured path is missing,
  falls back to shutil.which('opencode') before the linuxbrew last-resort.
- Dockerfile + README deploy notes: containerd import is sudoless via
  the group-readable raw socket (the microk8s ctr wrapper sudo-wraps).

Verified: rebuilt + reimported + rolled out; PR #5 (sha 985061c0) review
posted in-pod via the opencode engine (findings=2 inline=2 ok=True),
summary + 2 [CRITICAL] inline comments with suggestions + refs + sha marker.

Marcos 6e3a9eb5b0 feat: opencode review engine + .opencode factory
Replace the single Python model-call reviewer with an opencode agent
factory. A primary 'pragent' agent reads a brief (title/body/diff/config/
prior reviews), inspects the checked-out repo, runs the repo's own linters
via bash, loads review-methodology + findings-schema skills, and emits a
{summary, findings} JSON with per-finding severity/path/line/problem/fix/
suggestion/reference. Dormant security/tests/perf subagent lenses fan out
only on large/risky diffs (lean by default).

pilot/opencode_review.py: fetches the repo archive at the head sha into a
temp workdir, writes .pragent/brief.md, drops the factory, runs
'opencode run --pure --agent pragent --dir <workdir>' headlessly. Isolates
HOME (shared, warmed), strips ANTHROPIC_* env (leaked host vars caused
ProviderModelNotFoundError), stdin=DEVNULL (opencode blocks on stdin),
maps the bare OLLAMA_MODEL to the provider-prefixed ref. No Gitea I/O —
ai_review.review_pr parses + anchors + posts (reuses all v2 logic/tests).

PRAGENT_ENGINE=opencode (default) selects it; =ollama keeps the legacy
direct-call path. Verified end-to-end: posts a real review with a summary
section, inline [CRITICAL]/[HIGH] comments + apply-able suggestions +
reference links, and the sha dedupe marker. 49 tests pass.
