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.
