LiveReview auto-approving a low-risk change while routing a risky change to a human reviewer. Click to play.
+ +The risk score blends three signals: + +- Semantic LLM analysis +- A custom ML model trained on your production risk signals +- Static graph-based codebase analysis + +Inspired by Meta's RADAR paper: **50x** fewer production incidents, **3x** fewer rollbacks, **35%** faster reviews. + +How it works: + +1. **Track outcomes** - trace production incidents and rollbacks back to the commits and reviews behind them. +2. **Learn from the data** - combine those outcomes with LLM analysis, static checks, and ML signals into a risk score per change. +3. **Automate selectively** - auto-approve the lowest-risk 30-50% of changes. Choose a conservative, balanced, or aggressive policy. Risky or uncertain changes still go to a human. +4. **Keep improving** - track incidents, false approvals, and overrides, and tighten or loosen the policy as real data comes in. + + +## Within-Diff Prioritization: Blast Radius & Review Priority + +For everything that still goes to a human, LiveReview scores every hunk of a diff by **blast radius**: how far a change reaches through your call graph, how much persistent state it touches, and how well-tested it is. A 3-line change to a shared auth check can outrank a 300-line UI tweak. Your team's attention goes to the highest-risk code first, not spread evenly across every diff. https://github.com/user-attachments/assets/b7663ad5-e792-4d24-8452-18bbb9b958a0 @@ -51,7 +80,7 @@ LiveReview organizes around five capabilities, each answering a question your te | Pillar | Question it answers | What it covers | |---|---|---| -| [**Review**](#org-wide-harness) | Can we get both speed and quality? | Multi-level review checkpoints (commit, push, MR/PR, CI/CD, scheduled), [Adaptive Reviews](#adaptive-reviews) | +| [**Review**](#org-wide-harness) | Can we get both speed and quality? | Multi-level review checkpoints (commit, push, MR/PR, CI/CD, scheduled), [Auto-Approve](#auto-approve), [Adaptive Reviews](#adaptive-reviews) | | [**Understand**](#features) | Can an engineer quickly understand what changed and what it means? | Summary decks, Issue Navigator, PR summaries, [Cognitive Coverage / PR Quizzes](#cognitive-coverage) | | [**Enforce**](#repository-rules) | Can we make our engineering standards and review policies actually happen? | [Repository Rules](#repository-rules), [CI/CD Gates](#cicd-gates), custom prompts, scheduled reviews | | [**Improve**](#impact-report) | How are we doing, and where should engineering improve? | [Impact Report](#impact-report), [Livi / Data-Backed Decisions](#data-backed-decisions) | @@ -66,7 +95,8 @@ The result: engineering becomes a business advantage.

It shows the setup, the tests, the results, and the + threshold settings. Every number on this page comes from a real, repeatable test. You can re-run each test + yourself with the commands in the Setup tab. +
+ +| What is the risk threshold today? | P20. The model approves only the safest 20% of an org's own recent reviews, and blocks the other 80%. A bigger number lets more through — see the row below and the Thresholds tab. |
| Is that threshold a fixed number? | No. P20 is a setting an admin picks. The score that counts as "the safest 20%" is recalculated from the org's own recent reviews. Two orgs with the same P20 setting can have different cutoff scores. See the Thresholds tab. |
| What does a score of 0.42 mean? | Scores run from 0 (looks safe) to 1 (looks risky). 0.42 is below the middle. A brand-new org with no history uses 0.5 as a placeholder cutoff. An org with real history almost never uses 0.5 — it uses its own calculated cutoff instead. See Quick Facts #4 below. |
| Does the model learn from mistakes? | Yes. When a human reports that a merged PR caused a revert or an incident, the model takes one learning step the same day. A nightly job also re-fits the model from scratch and checks it did not get worse. See the Tests and Explain tabs. |
| Where do I change the settings? | Settings → Auto Approve Policy, in the LiveReview app. Not on this page — this page only reports what the code does. |
This needs its own fact because it caused confusion. Here is the full explanation in order.
+A score has no fixed meaning by itself. 0.42 only means something next to a cutoff.
A brand-new org, with zero scored reviews, has no history to calculate a cutoff from. The code falls back to a placeholder cutoff of 0.5.
0.42 is below 0.5. So even on day one, a docs-only edit is approved. It is close to the placeholder line, but it is on the approved side.
Once an org has real review history, the placeholder 0.5 is never used again. The cutoff becomes "the score at the 20th percentile of my own recent reviews." The Thresholds tab shows this cutoff is usually different from 0.5, and is often much higher for a typical org.
What this means for you: 0.42 is not a sign that the model thinks a docs-only edit is risky. It is a sign that the placeholder cutoff (0.5) sits close to where ordinary, low-risk changes land. This is a known, reasonable property of the cold-start fallback, not a bug — but it is also why the placeholder cutoff should never be shown without this explanation next to it. This report no longer does that.
+Each test case is one block of plain data. It is not a database row. It is not a Go struct that only a
+ programmer can read. It is a JSON file:
+ internal/policyengine/testdata/scenarios.json.
{
+ "name": "readme-only-edit",
+ "rationale": "Docs-only change, no code risk at all.",
+ "blast_hunks": [],
+ "findings": [],
+ "llm_class": { "class": "docs-only", "confidence": 9 },
+ "diff": { "file_count": 1, "lines_added": 8 },
+ "author_level": 2,
+ "want": { "approve": true }
+}
+ Anyone can read this file and understand the test case without running any code.
+The test code reads this file. For each case, it writes a real review row into a real test database, with
+ the blast radius, the findings, and the LLM class from the JSON. Then it calls the real
+ decision function, engine.RunWithPolicy. This is the same function the
+ LiveReview app calls on a real pull request. The test does not re-implement the decision logic. It runs the
+ real logic and checks the real answer against the want field in the JSON.
Every row a test writes is deleted right after the test finishes. This happens even if the test fails or + crashes. We checked this by running the whole test suite twice in a row and counting rows before and + after. The count was zero both times, for every table.
+| Table | Rows left over |
|---|---|
| orgs, users, reviews | 0 |
| blast_radius_hunks | 0 |
| risk_feature_snapshots | 0 |
| review_outcomes | 0 |
| review_policy_log | 0 |
| risk_model_versions | 0 |
| ci_rulesets | 0 |
Because of this, you can run these tests again and again, on any database, including a live one, and + never need to clean up by hand.

Every number on this page — every score, every weight, every approval rate — is embedded in the page as + data, not typed in by hand. If you change the model's weights, the scenario corpus, or the reference mix + the Thresholds tab compares against, this page will go stale unless you regenerate it. There is one command + for that:
+make regen-risk-report +# or directly: +python3 scripts/regen_risk_report.py+
This script runs the same three tests listed above, reads the structured data they print (lines starting
+ with SCDATA:, TDDATA:,
+ TDSAME:, LCDATA:), and replaces this page's embedded
+ data with exactly what the tests just computed. It refuses to run if any of the three tests fail, so this
+ page can never embed a number from a broken test run. Run it, then check the diff — a page that changed
+ more than you expected is itself useful information.
Each group checks a different part of the system. Click a bucket chip below to see its test cases in the + Results tab.
+ +internal/riskscore/model.go,
+ these tests are your first line of defense. A failure here means "the formula itself is wrong," separate
+ from "this one test case is wrong."Every review gets one number from 0 to 1, called the score. 0 means "looks safe." 1 means + "looks risky." The score by itself tells you nothing — you always need to compare it to a + cutoff. If the score is at or above the cutoff, the review is blocked. If it is below the + cutoff, it is approved. The Percentile column below answers "where does this score sit, + compared to a realistic set of other reviews" — see the Thresholds tab for exactly what that reference set is.
+score = sigmoid( bias + sum of ( weight × category_multiplier × value ) for every signal )+
There is no other step. No large language model makes this call — it is one weighted sum, squeezed into the
+ 0-to-1 range by one standard function (sigmoid). Every signal's allowed range is
+ listed in the Signal Reference table below, so you can judge for yourself what a normal value looks like.
This is every signal the model has, nothing collapsed or hidden — 19 in total. The
+ "Starting weight" and "Starting category dial" columns are the hand-set defaults from
+ internal/riskscore/model.go's Prior() /
+ DefaultCategoryMultiplier. The category dial is the same number the Settings
+ UI's weight sliders show before an admin ever touches one — change it there, and this signal's effective
+ weight (weight × dial) changes immediately, for every future score.
| Signal | What it measures | Allowed range | Starting weight | Starting category dial |
|---|---|---|---|---|
| br_sum | Total blast-radius score, added up across every changed section ("hunk") in the diff | 0 and up. Each hunk's own score is 0–100 by convention, but a diff with many hunks can sum past 100. | 0.020 | ×2.00 (blast radius) |
| br_max | The single highest-scoring hunk in the diff | 0–100 | 0.010 | ×2.00 (blast radius) |

Yes — every category the Settings UI shows a weight slider for (performance, developer experience, and + the rest) has its own dedicated signal here, its own starting weight, and its own starting dial. None of + them are special-cased out of learning: a batch re-build or a real-time nudge updates every weight in this + list together, in the same pass, using whichever of these counts were actually nonzero in the training + reports it saw (see "Why did `critical_count`'s weight drop so much?" below for what happens to a category + a training batch never touches).
+| Signal | Taxonomy category | Allowed range | Starting weight | Starting category dial |
|---|---|---|---|---|
| security_count | Security | 0 to 500 | 0.550 | ×1.50 |
| reliability_count | Reliability | 0 to 500 | 0.300 | ×1.25 |

That's 10 categories (security plus these 9), matching the Settings UI's Risk Model sub-tab exactly — the
+ same list the auto-approve settings page stopped hiding under a collapsed "Other" section. A category
+ dial of ×1.00 is not "this category is ignored" — it means "not weighted
+ up or down relative to the others yet," and an admin can move any of these 10 dials independently at any
+ time; the change takes effect on the very next score, with no retrain needed.
The compression note: files_changed and
+ lines_added are passed through a squeezing step (log1p)
+ before they reach the formula above. This is on purpose: without it, a diff with 10× more files would
+ add exactly 10× more to the score, and a huge but otherwise harmless diff (like a generated file or a
+ big rename) would dominate the result. After squeezing, going from 1 file to 10 files adds much less than
+ going from 10 files to 100 — the signal still counts, but it cannot run away unbounded.

The threshold is a percentile, written as P10, P20,
+ and so on. P20 means: approve only the safest 20% of this org's recent reviews,
+ and block the other 80%. A lower number is stricter (it approves less, blocks more). A higher number is
+ more relaxed (it approves more, blocks less). Today's default is P20.
We built a test with 60 made-up reviews, shaped like a realistic repository's recent history: mostly small, + clean changes, a smaller group of medium-risk changes, and a few clearly risky ones. We then checked what + each percentile setting actually does to that mix.
+We included the two extreme edges, P0 and P100,
+ on purpose — they are the settings that should be easiest to reason about, so they double as a check that
+ the dial behaves the way anyone would expect.
| Setting | Plain meaning | Cutoff score | % of reviews approved |
|---|
The two edges, explained precisely:
+P0 approves … of
+ the … reviews, including the safest one in the set (a docs-only edit).
+ The cutoff at P0 is the single lowest score in the whole mix, and nothing can score strictly below the
+ lowest score in its own set — so at the strictest possible setting, everything is blocked, with no
+ exceptions. This is proven by a passing test, not just described:
+ go test ./internal/riskscore/... -run TestThresholdExperiment -v.P100 approves … of
+ … reviews — every one except the single riskiest review in
+ the set. The cutoff at P100 is the single highest score in the mix, and that one review can never score
+ strictly below its own value, so it alone stays blocked even at the most relaxed possible setting. "P100
+ allows everything" is almost true, but not quite: one review is still blocked, by definition, no matter
+ how relaxed the setting is.Not just a handful of hand-picked examples — the full dataset. Click a column to sort it. A dash + (—) means the risk score never ran for that case (something earlier, like + the author's level, already decided the outcome), so there is no score to compare against a cutoff.
+Read the "one critical security finding" row carefully: at P80,
+ it flips to approved, in this test mix. This is not a bug. It is a real warning about what "very
+ relaxed" means: at a high enough percentile, the cutoff score itself can rise above a genuinely risky
+ review, if the rest of the reference mix was also fairly risky. This is the actual, concrete reason
+ the default is P20 and not something looser.
We ran the exact same setting, P20, against two different made-up histories:
+ a "quiet" org whose recent reviews mostly scored low, and a "busy" org whose recent reviews mostly scored
+ higher.
| Org | Recent review scores (made up, for this test) | Setting | Resulting cutoff |
|---|---|---|---|
| Quiet org | mostly 0.20–0.38 | P20 | … |
| Busy org | mostly 0.50–0.86 | P20 | … |
Same setting. Two different cutoff numbers. The setting (the percentile, like P20) stays fixed + until an admin changes it. The number it turns into (the cutoff score) is recalculated from the org's own + recent history, automatically, with no admin action needed. These are two different things, and + this is the whole answer to "is the threshold static."

| 2 | After one more outcome report arrives live, with no model re-build. | … |
Why the score moved: the actual weight changes, not just the score. We printed every + weight, before and after. The ones that moved the most are exactly the ones that measure blast radius, + because blast radius was the one pattern in the training reports:
+| Weight | Before | After | Change |
|---|
Why did critical_count's weight drop so much? Because none
+ of the 40 outcome reports in this test mentioned a critical finding — every single one of them only
+ varied blast radius. A fresh model re-build only learns from the patterns actually present in its
+ training reports. With no evidence either way about critical findings, the re-build pulls that weight
+ most of the way back toward a low, cautious value, instead of keeping the full hand-set starting weight.
+ In a real org, outcome reports would come from many different kinds of problems, not just
+ one — this specific, large drop is a property of this test's narrow, single-pattern made-up
+ data, not something to expect in production. It is a real and useful thing to know if you are ever
+ reading a weight-change log and wondering why an untouched category moved.
Total movement for the held-out review: … → + …, caused only by outcome reports, with no admin touching a + weight by hand. That is the direct proof that reporting an incident in the real app is not a + dead button.
+ +storage/reviews/taxonomy_report_store.go, buildWhereClause.A Risk-Based Auto-Approve Policy for Code Review
+LiveReview can now auto-approve a pull request it has measured to be low-risk. This is not a shortcut. The + robot runs a real check — several checks, in fact — before it decides anything. A human still + reviews every change that the robot's checks flag as uncertain or risky.
+The design is not a guess. It follows Meta's published RADAR system, a layered approach to exactly this + problem at much larger scale. LiveReview already shared three of RADAR's five architectural pieces before + this project started; we built the remaining two.
+The result has been tested, not just built. Forty-six hand-written scenarios exercise every decision path + the system can take. A live dashboard now shows, for each customer org, how many pull requests were + approved, how many were blocked, how often a human overrode the robot, and how often an approval turned out + to be wrong. Reviewer attention shifts from "every pull request" to "the pull requests that actually carry + risk" — and we can show our work.
+LiveReview Ships Risk-Based Auto-Approval, Returning Reviewer Hours Without Lowering the Bar on + Risky Changes
+ +A team merging a hundred pull requests a week gives each one the same scrutiny. A one-line fix to a README + gets read as carefully as a change to a billing calculation. That isn't rigor. It's an even coat of + attention spread across a distribution that is anything but even — a small number of changes carry + almost all of the actual risk, and the rest carry almost none.
+Reviewer attention is the scarcest resource in this loop. It does not scale the way compute does. Ask a + person to carefully read a hundred boring diffs a week, and eventually they stop reading carefully. That is + not laziness. It is what happens to any human asked to apply full attention to a task that rarely rewards + it.
+Today, most teams have no lever for this problem beyond "review everything" or "review nothing." There is + no middle setting that says: trust the obviously safe changes, and keep full scrutiny on everything else.
+ +LiveReview's auto-approve policy is that middle setting. A pull request now passes through a layered funnel + of checks — eligibility, static rules, a trained risk score, and an independent LLM classification + — before the system decides whether a human needs to look at it before merge, or whether the robot's + own checks are enough for now.
+Every check still runs. Nothing about auto-approve means less checking — it means a different + checker. Each stage writes down its own verdict, so "why was this approved" is always an answerable + question, never a shrug. Any single stage can block the change outright, no matter what the other stages + concluded.
+The threshold for "safe enough" is a dial, calibrated against each customer's own recent history, not one
+ fixed number forced on every team regardless of their risk profile. Turning the feature on costs nothing
+ permanent: an org can set always_approve or never_approve
+ on a specific repository, and a human can force an override on any single decision, in either direction, at
+ any time.
An org owner sets a starting percentile under Settings → Auto Approve Policy, watches the new Reports + → Auto Approve dashboard for a week, and adjusts the dial using their own measured override rate and + false-approve rate — not a guess, and not somebody else's benchmark.
+Pull request volume per engineer has grown faster than the careful, structured review process it gets + pushed through. That process was built for a slower rate of change, and it has not been redesigned to match + the new one — it has just been asked to go faster, which quietly means going shallower.
+The risk in a typical week's changes is not evenly spread. A small fraction of pull requests carry nearly + all of the blast radius — the reach of a change through the rest of the codebase — while the + majority carry almost none. Equal scrutiny on every change means most reviewer time is spent on changes that + were never going to fail.
+Every customer running LiveReview today is already paying this cost in reviewer hours, whether or not + anyone has measured it. Until now, there was no way to measure it, which made it easy to ignore and + impossible to improve on purpose.
+This is a mechanism change, not a headcount change. The lever here is how review attention gets allocated, + not how many reviewers exist on a team. It pays off immediately, without a single new hire.
+We did not invent this pattern from scratch. The design follows Meta's published RADAR system (arxiv + 2605.30208): a layered funnel — eligibility, deterministic gates, a trained risk score, LLM semantic + classification, and a final decision — rather than one opaque model making the entire call alone.
+ +Three lessons from that published system were carried over deliberately, because they came from a system + already proven at a scale ours has not reached yet. First, a risk threshold must be a per-org dial, never + one fixed cutoff applied everywhere — RADAR's own experiment comparing a strict and a lenient setting + showed exactly why a single global number does not hold up across different teams. Second, safety outcomes + — a revert, an incident, a confirmed-safe merge — must feed back into the model's calibration, or + the system never learns from the very thing it exists to prevent. Third, the system must stay legible. Every + decision shows its reasoning, stage by stage, never only a verdict with no explanation attached.
+We also did not start from a blank page. Three of RADAR's five architectural ingredients already existed + inside LiveReview in a different form before this project began: static rule gates (reused from the existing + CI/CD gate system), per-finding severity and confidence scores (already produced by LiveReview's review + engine), and blast-radius scoring (already computed per code change). The two genuinely new pieces were + eligibility — deciding who can be considered for auto-approval at all — and the trained risk + score itself.
+What this buys the customer is simple: the architectural risk of "will this kind of system work at all" has + already been retired by someone else's production deployment. What's actually new, and what actually needed + building, is the integration into LiveReview's own review pipeline and its own ten-category finding + taxonomy.
+Eligibility and static rules run first, and they are built to be simple on purpose. A rule that can be + explained in one sentence is a rule that can be audited in one sentence. Either stage can block a change + outright, no matter what a trained model further down the funnel would have concluded.
+The risk score itself is a logistic regression — one of the oldest, most explainable models available + — scoring blast radius and ten categories of finding severity into a single number between zero and + one. A simpler, explainable model was chosen deliberately over a more powerful but opaque one, because this + number decides whether a human ever looks at the code. In plain terms, the model works like this:
+z = bias + sum over every signal of (its value x its weight x its category importance) +score = squash(z) into a number between 0 and 1, where higher means riskier+
The LLM classification check runs beside the risk score, not behind it. Either one objecting blocks the + change on its own, and the system records exactly which one objected and why — a disqualifying + classification can override a safe-looking score, and a borderline score can be cleared by a confident, safe + classification.
+The threshold itself is relative, not absolute. The cutoff is a percentile measured against the customer's + own recent score history, so the same percentile setting resolves to a different number for a quiet + repository than for one in the middle of an incident spree — on purpose, because "safe enough" means + something different in those two situations.
+Finally, the model watches its own track record. Every outcome reported from production — a revert, + an incident, a confirmed-safe merge — nudges the model immediately by a small, careful amount. A + slower, periodic batch refit retrains the whole model from its full history, and that retrained model is + only promoted into production if it measurably performs at least as well as the one already live.
+ +A claim this specific deserves more than a demo. Forty-six hand-written scenarios run through the actual + production decision path — every stage of the funnel, all ten finding categories, every mode + shortcut, every threshold boundary — and none of them are reimplemented separately from the real code. + If the real engine changes, these scenarios run against the change directly.
+ +| What was measured | Result |
|---|---|
| Scenario coverage | 46 cases, every funnel stage and finding category |
| Strictest threshold setting (P0) | Approves 0 of a realistic 60-review mix |
| Most lenient setting (P100) | Approves every review except the single riskiest one |
| Model after cold start | Scored a risky held-out review at 0.668 |
| Same review, after a batch refit on real outcomes | 0.975 (held-out AUC: 1.000) |
| Same review, after one more reported outcome | 0.999 |
| A genuinely safer held-out review, same sequence | Moved the opposite direction (0.416 to 0.371) |
The threshold dial is measured, not asserted. A real experiment computes exactly + what each percentile setting resolves to on a realistic mix of reviews, including both extremes stated + precisely: the strictest possible setting approves nothing in the mix, and the most lenient possible setting + approves everything except the single riskiest item — because nothing in a sorted list of scores can + fall below its own maximum.
+The learning loop is proven with real numbers, not described in the abstract. A held-out risky review's + score moved from 0.668 to 0.975 to 0.999 as real outcomes were applied to the model in sequence, while a + genuinely safer held-out review moved in the opposite direction over the same run — evidence of + discrimination between the two, not simple upward drift.
+A real limitation is named here on purpose, instead of left out. One feature's learned weight can + under-update when the training data never varies it at all — found, measured, and written down rather + than smoothed over, because an evidence section that only shows wins is not evidence.
+Production trust does not stop at a test suite. A live Reports → Auto Approve dashboard shows an org's + own score distribution plotted against its real cutoff, its real approve-and-block counts over time, its + real override rate, and a real false-approve rate computed from outcomes reported on actual production + traffic.
+Translate the mechanism into the customer's own units, and the trade becomes concrete. At a representative + 500 pull requests a month, a 60% auto-approval rate, and a measured 1% false-approve rate, the arithmetic + looks like this:
+reviewer-hours returned = 300 auto-approved PRs x 15 min saved / 60 = 75 hours/month +false approvals = 300 auto-approved PRs x 1% = 3 reviews/month +expected incident cost = 3 x (illustrative $2,000 cleanup cost) = $6,000/month+
Whether that trade is worth it depends entirely on what a team's own reviewer-hours and its own incident + costs are worth — there is no universal answer — but the customer can now run this exact + arithmetic with their own real numbers instead of guessing.
+The percentile dial is the customer's lever, and for the first time it is visible. A more conservative + setting costs more reviewer time and buys a lower false-approve rate. A more lenient setting trades the + other way. Neither choice is hidden behind a black box; both are measured, per organization, continuously.
+An override rate that climbs over time is an early warning the customer gets for free. It surfaces policy + drift before an incident would have told the same story — often days or weeks earlier, while there is + still time to adjust the dial rather than clean up afterward.
+Nothing about this is a one-way door. always_approve and
+ never_approve exist per repository for teams who already know their own risk
+ profile. The static-rule check can never be silenced by a mode override — "we trust this repository"
+ is never allowed to quietly become "ignore a leaked credential." And any single decision, in either
+ direction, can be overridden by a human at any time, with that override logged and counted.
A brand-new customer org has no score history to calibrate a percentile against on day one. The system + falls back to an explicit, conservative fixed cutoff in that case, rather than silently assuming everything + is safe until enough real history accumulates.
+Thin training data can under-protect a feature, as the documented weight-collapse case shows. The + batch-refit promotion gate — never promote a model that performs worse than the one already live + — is the deliberate safeguard against that kind of drift reaching production unnoticed.
+This system is one layer in a funnel, not the last line of defense. The static-rule check and the + independent LLM classification exist specifically so that no single signal is ever the only thing standing + between a risky change and production.
+One capability was scoped and deliberately set aside for a later phase: a live, observe-only mode that + would let a new customer watch the policy's decisions on real incoming traffic before trusting it to act. It + is a known next step, named here rather than hidden, and the three measurement views described above were + prioritized first because they work against decisions the system is already making today.
+No. It means the + review that happens is concentrated on changes that carry actual risk, instead of spread evenly across + everything regardless of risk.
The policy + falls back to an explicit, conservative, fixed cutoff until enough real reviews accumulate for a percentile + to be calculated against the org's own data.
Yes. Mode and threshold are both configurable per repository, and a repository without its own + setting simply inherits the organization's default.
Three independent checks must all agree that nothing is wrong — eligibility, static + rules, and the risk-score-plus-LLM pair — and any one of them can block the change by itself.
It deliberately includes adversarial cases built to fail a naive approach — for example, a + high-blast-radius change with zero flagged findings, the exact pattern a severity-only check would miss + entirely.
This is now a measured, per-org number on the Reports → Auto Approve dashboard, not an + estimate — and it is the number that should gate any decision to widen the rollout.
Explainability is a requirement here, not a nice-to-have, because the model's output decides + whether a human ever sees the code at all. RADAR made the same choice, for the same reason.
Treat it as the earliest available signal that a threshold or a model weight has drifted out of + step with that org's current reality, and investigate before an incident does the same job the hard + way.
