feat: fix agents deliver the patch a reviewer approved

A high-confidence finding that names a source file starts a fix agent in its own copy of the repository. The fix agent writes the fix and a regression test. A second agent reviews the patch without editing it: it runs the new test on the unpatched code and rejects a test that passes there, then looks for other routes to the bug. A rejected fix gets one more attempt with the reviewer's reasons. Only an approved patch is kept. It is written to the run directory as fixes/<finding>.patch, and each approved patch becomes one local branch on top of the scanned commit. Nothing is pushed. - strix fix RUN [FINDING ...] fixes findings of a saved scan. - --no-auto-fix turns fix agents off for a scan.

-[Vercel AI Gateway](https://vercel.com/docs/ai-gateway) provides an OpenAI-compatible API for models from multiple providers.
+[Vercel AI Gateway](https://vercel.com/docs/ai-gateway) provides access to 100+ models from multiple providers through one OpenAI-compatible API.

 ## Setup

 Create an [AI Gateway API key](https://vercel.com/docs/ai-gateway/authentication-and-byok), then configure Strix:

 ```bash
-export STRIX_LLM="openai/anthropic/claude-opus-5"
+export STRIX_LLM="vercel_ai_gateway/zai/glm-5.3"
 export LLM_API_KEY="your-ai-gateway-api-key"
-export LLM_API_BASE="https://ai-gateway.vercel.sh/v1"
 ```

-The first `openai/` segment tells Strix to use its OpenAI-compatible client. The remaining value is the [AI Gateway model ID](https://vercel.com/docs/ai-gateway/models-and-providers).
+The `vercel_ai_gateway/` prefix selects the Gateway. The remaining value is the [AI Gateway model ID](https://vercel.com/docs/ai-gateway/models-and-providers).

 ## Available Models

+| GLM-5.3 Flash | `vercel_ai_gateway/zai/glm-5.3-flash` |
+
+OpenAI, Anthropic and Gemini models keep their provider safeguards on the Gateway. Security testing with them needs [Daybreak](https://openai.com/daybreak/), [CVP](https://support.claude.com/en/articles/14604842-cyber-verification-program) or [Fairwind](https://deepmind.google/fairwind-program/) access.

+## Fix Findings
+
+A full source code scan prepares a patch for each confirmed finding that points
+at source code. `strix fix` does the same work for an earlier scan and does not
+scan again.
+
+```bash
+strix fix <run>                      # every confirmed finding that has no patch
+strix fix <run> vuln-0003 vuln-0007  # only these findings
+strix fix <run> vuln-0003 --max-budget 10
+```
+
+`<run>` is the run name, which is the folder name under `./strix_runs`. Scan
+options such as `--max-budget` and `--config` go after the finding IDs. A
+finding that you name does not need high confidence, and a new approved patch
+replaces its earlier patch.
+
+For each finding, a fix agent writes the patch and a regression test in a copy
+of the repository. A second agent reviews the result and cannot edit it. The
+second agent rejects a regression test that passes on the code without the
+patch. After a rejection, the fix agent gets one more attempt. Strix saves only
+an approved patch.
+
+Strix delivers an approved patch in two forms:
+
+- A patch file, `fixes/<finding-id>.patch`, in the run folder. Apply it with
+  `git apply`.
+- A local branch, `strix/fix-<finding-id>-<digest>`, in the repository that you
+  scanned. The branch has one commit on top of the commit that you scanned.
+
+Strix does not change your working tree, your index, or your current branch.
+Strix does not push the branch. Uncommitted changes that were in the directory
+during the scan are not in the branch. If the patch does not apply to the
+scanned commit, Strix makes no branch and the patch file stays available.
+
+`strix fix` exits with `0` when every requested finding has an approved patch.
+It exits with `2` when a finding has no approved patch, and with `1` after a
+fatal error.

 - CLOSURE DISCIPLINE: every candidate you open ends in exactly one explicit state — `confirmed` (working PoC, or a complete source→control→sink→impact trace that is reachable), `ruled_out` (you can name the SPECIFIC control, at a location, that runs on every attacker-reachable path before the sink), or `open_proof_gap` (plausible, unconfirmed, and you could NOT name such a control). "I moved on" is not a closure state. Silently dropping an uncertain candidate is mislabelling an `open_proof_gap` as `ruled_out` and is how real bugs get missed.
 - Missing information is NOT proof of safety: no caller found, can't tell if deployed/exposed, couldn't stand up the service, build failed — each is an `open_proof_gap`, never a reason to mark a candidate clean. Difficulty is a reason to defer, not to suppress.
- COVERAGE: record every surface you assess with `record_coverage` (surface + risk area + outcome + evidence), including the ones that came back clean — a report that only lists findings cannot say what was reviewed and cleared. Use the `needs_follow_up` outcome for anything left in an `open_proof_gap` state, and carry the same items up in `agent_finish(open_items=[...])`. The ledger is shared and mutable: when you resolve a surface another agent left open — or find that a closed one is not — move that entry with `update_coverage` instead of recording a second one for the same surface.

 - THREAT MODEL: before you start testing, call `get_threat_model` on the target you were pointed at — it is the scan's shared answer to who the attacker is, where the trust boundaries sit, and what counts as critical here. It is scoped to this scan and nothing carries over from an earlier run, so `found: false` means no agent on this run has derived one yet. Read it instead of re-deriving trust boundaries yourself; where your testing disproves it — a boundary it calls trusted turns out to be attacker-reachable, a role it did not know about, a host or endpoint it never listed — record that with `amend_threat_model` so the agents after you inherit the correction. Amending is not optional politeness: a model nobody corrects turns the first agent's guesses into everyone's assumptions.

+2. A fix agent edits and tests the copy.
+3. The copy is hashed. A read-only reviewer then checks that copy.
+4. The patch is delivered only when the reviewer approved and the hash is the
+   same after the review as before it. A rejected patch goes back to a fix

+The delivered patch is the difference between the copy as it started and the

 ### Usage / reachability analysis (required for every dependency CVE)

-For every CVE you are about to report, run a static usage analysis and record
-the result in the structured `reachability` + `reachability_evidence` fields,
-and report every usage site you find as a `code_locations` entry (see Reporting).
-The level is an **evidence ladder, never an exploitability verdict** — claim
-only what you proved, and cite the proof. It never changes severity (that is
-`advisory_cvss` alone); it exists so the reader can prioritize.
+Every CVE you report carries a verdict in `reachability`, the proof in
+`reachability_evidence`, and every usage site in `code_locations` (see
+Reporting). The verdict answers one question for THIS advisory in THIS
+codebase: does the vulnerable code run here? There are three answers and no
+"unknown". The tool rejects a report without a verdict or without evidence,
+so finish the analysis before you file.

-**Go — use govulncheck (real call-graph analysis):**
+- **`reachable`** — the advisory's vulnerable code executes in this codebase:
+  application code, or a package it calls on the application's behalf, calls
+  the affected function, mode or feature. Evidence: the call site as
+  `file:line` and the source-to-sink trace (step 3).
+- **`not_reachable`** — the package is loaded by the shipped code, but this
+  CVE's vulnerable path does not execute here. Evidence: what you checked and
+  why the path is dead. Typical reasons: no caller of the affected API after
+  a complete search; the only call site is behind a condition that is false
+  here (a polyfill for an older runtime, a flag that is off, a dev-only
+  command); the parent package of a transitive dependency never references
+  the affected API; the flaw sits in a mode or option this code never uses;
+  the argument that triggers the flaw is a constant here.
+- **`not_applicable`** — the advisory does not apply to this codebase at all:
+  nothing the shipped code loads imports the package; it is build, test or
+  dev tooling the artifact never executes; the installed copy is a patched or
+  unaffected build; the flaw is specific to a platform this code does not run
+  on; or the only code that could use it cannot be inspected (a compiled
+  blob, a private bundle with no source) and nothing you can inspect reaches
+  it. Evidence: the search scope and the negative result.

-```bash
-# Symbol-level: reports only vulnerabilities whose vulnerable functions are
-# actually reachable from application code. Needs the Go toolchain + module
-# deps; if either is missing, fall back to the checks below rather than
-# claiming a level.
-if command -v govulncheck >/dev/null && go version >/dev/null 2>&1; then
-  govulncheck -format json ./... > "$ART/govulncheck.json" || true
-fi
-```
+The verdict is per CVE, not per package. Sibling CVEs on one package usually
+affect different symbols or modes (one hits a parser, another a header
+check): run the check against each advisory's own affected functions and
+never copy one CVE's verdict or evidence onto another. The import check
+(step 1) is the only step shared across a package's CVEs.

- A finding with a call stack ⇒ `reachability=reachable_call_path`, put the
-  call-path excerpt (entrypoint → vulnerable function) in
-  `reachability_evidence`.
- Listed as affecting a required module but with no reachable symbol ⇒ fall
-  back to the import/symbol checks below (`imported` / `not_imported`).
+`reachable` is not an exploit, and `not_reachable` / `not_applicable` are
+not proof of safety (dynamic `import()`, reflection and framework wiring
+evade static search). Say what you checked; never write "not exploitable".

-**All other ecosystems — import check, then symbol match:**
+**Procedure**

 1. **Import check.** Search application code (exclude lockfiles, vendored
-   deps, `node_modules`, build output) for imports of the vulnerable package:
-   `ast-grep`/`rg` for `import`/`require`/`from X import` of the package (and
-   its ecosystem import name, which may differ from the registry name, e.g.
-   `PyYAML` → `yaml`). No hits ⇒ `not_imported`, with the search scope stated
-   in `reachability_evidence`. For a **transitive** dependency, the check is
-   whether application code imports it directly; if not, it is reachable only
-   through the direct dependency — check whether the direct dep's usage can
-   hit it (if unclear, use `imported` when the direct dep is used at all).
-2. **Symbol match — per CVE, not per package.** Read each CVE's own advisory
-   (GHSA/NVD/OSV `affected[].ecosystem_specific.imports` or the advisory
-   text) for the affected functions/classes/APIs. Search application code for
-   those symbols (`ast-grep` pattern or `rg -n`). Hits ⇒
-   `vulnerable_symbol_used`, with repo-relative `file:line` of each hit (up
-   to a handful) in `reachability_evidence`. Imported but no affected-symbol
-   usage found (or the advisory names no symbols) ⇒ `imported`.
-   Different CVEs on the same package usually affect **different** symbols
-   (one hits a parser, another a header check) — never copy one CVE's
-   verdict/evidence onto its siblings; run the symbol search against each
-   CVE's own affected-symbol list. The import check (step 1) is the only
-   part shared across a package's CVEs.
-3. **Source-to-sink trace — do this whenever step 2 found a symbol hit.** A
-   symbol hit alone says the code calls the vulnerable API; it does not say
-   who can reach it. Start at the sink (the exact line that calls the
-   vulnerable function) and walk backwards hop by hop to the source: the
-   entry point that carries untrusted input (HTTP route, CLI argument, queue
-   or webhook payload, uploaded file, config value). Read each intermediate
-   function; when a hop is a thin wrapper, go one step deeper — never stop at
-   the first caller. Record what each hop enforces: authentication, a role
-   check, validation, a feature flag, a size or type limit, a default that is
-   off in production.
-   Write the chain into `reachability_evidence` as
-   `entry point -> intermediate call -> package call` with a
-   repository-relative `file:line` for every hop, and say who controls the
-   input. If no source reaches the sink, say that too — the level stays
-   `vulnerable_symbol_used` (the call is real), and the trace is what tells
-   the reader it is only reachable from, say, an operator CLI.
-4. If the analysis was not performed or is inconclusive (obfuscated code,
-   dynamic loading, unparsable sources) ⇒ `unknown` and say why in
-   `assumptions`.
+   deps, `node_modules`, build output) for imports of the vulnerable package
+   under its ecosystem import name (`PyYAML` → `yaml`): `ast-grep`/`rg` for
+   `import`/`require`/`from X import`. For a **transitive** dependency nothing
+   in application code imports it, so walk every introducing chain from the
+   lockfile (e.g. `express > body-parser > qs`) and inspect the code of the
+   package one hop above the vulnerable one on each chain (`body-parser`, not
+   just `express`; its installed sources, or the class references of its
+   jar). Nothing imports it and no chain loads it ⇒ `not_applicable`, citing
+   the scope you searched. Loaded ⇒ continue.
+2. **Affected-symbol check, per CVE.** Read the advisory (GHSA/NVD/OSV
+   `affected[].ecosystem_specific.imports`, the advisory text, the fix commit
+   when the text is vague) for the functions, classes, options or modes that
+   trigger the flaw. Search application code, and the parent package of a
+   transitive dependency, for them (`ast-grep` pattern or `rg -n`; sibling
+   CVEs can share one multi-pattern search per package). No caller after a
+   complete search ⇒ `not_reachable`, citing the symbols and the scope. A
+   caller ⇒ step 3. When the flaw is in code every use of the package runs
+   (the parser the package exists for), the import itself is the call site ⇒
+   step 3.
+3. **Source-to-sink trace.** Start at the sink (the exact line that calls the
+   affected function) and walk backwards hop by hop to the source: the entry
+   point that carries the input (HTTP route, CLI argument, queue or webhook
+   payload, uploaded file, config value). Read each intermediate function;
+   when a hop is a thin wrapper, go one step deeper — never stop at the first
+   caller. Read what reaches the function: a constant argument that cannot
+   contain the triggering pattern, a flag that is off, a runtime-version
+   gate, a path only a dev tool runs means the vulnerable path does not run
+   ⇒ `not_reachable`, citing the condition. Otherwise ⇒ `reachable`. Write
+   the chain into `reachability_evidence` as
+   `entry point -> intermediate call -> package call` with a repo-relative
+   `file:line` for every hop, what each hop enforces (authentication, a role
+   check, validation, a size or type limit), and who controls the input. A
+   trusted or operator-only source does not soften the verdict: the code
+   runs, so it is `reachable`, and the trace is what tells the reader who can
+   reach it; the contextual CVSS carries that.
+4. **Go — govulncheck first.** When the Go toolchain and module deps are
+   present, `govulncheck -format json ./... > "$ART/govulncheck.json"` gives a
+   real call graph: a finding with a call stack ⇒ `reachable`, with the call
+   path (entrypoint → vulnerable function) as the trace; an affected module
+   with no reachable symbol ⇒ `not_reachable` when application code imports
+   it (cite the govulncheck result and the import), `not_applicable` when
+   nothing imports it. When govulncheck cannot analyze the module (build
+   errors, missing deps), run steps 1–3 instead of guessing.

-Cheap-first budgeting: the import check is one search per package — always do
-it. Do the per-CVE symbol match for every CVE whose advisory names affected
-symbols (they can be batched into one multi-pattern search per package);
-prioritize `critical`/`high`/KEV when the budget is tight; a CVE whose symbol
-search was skipped may still be reported as `imported` (the import check is
-real evidence), but its `reachability_evidence` must state that the
-affected-symbol check was not performed, so a skipped search is never
-mistaken for a completed one with no hits. Never let this analysis stall
-reporting — `unknown` with a reason beats an unverified claim.
+Work in severity order (critical, high and KEV first) so that if time runs
+out the low tail is what is missing, and name that tail in the scan summary.
+A CVE whose analysis you did not finish is neither filed with a guessed
+verdict nor filed as `not_applicable`: finish it, or report the gap. Never let
+the usage analysis silently drop a CVE: every advisory the scanner matched is
+either filed with a verdict or named in the summary as not analyzed.

-Anti-overclaim rules:
+### Reachability is a verdict on the code path, not on severity

- `not_imported` still does NOT mean safe (dynamic `import()`/reflection/
-  framework wiring evade static search) — never phrase it as "not exploitable".
- `reachable_call_path` is reserved for call-graph tools (govulncheck); a

+name: query-language-injection
+description: Query-language injection testing for scalar search, filter, selector, and authorization inputs compiled into JSONPath, JMESPath, OData, Lucene, LDAP, Cypher, XPath, or similar expressions. Requires a per-sink four-cell balanced true/false matrix before generic spraying or no-issue closure
+---
+
+# Query-Language Injection
+
+An HTTP scalar becomes an injection sink when an application inserts it into a query, selector, policy, or expression string. The input may look like an exact-match value at the API boundary while becoming executable syntax in a downstream parser. Treat each accepted search, filter, selector, and authorization field as an independent sink.
+
+## Non-Skippable First Pass
+
+Make this the first test after baselines. Do not begin generic SQL, NoSQL, wildcard, metacharacter, or product-specific spraying until every candidate scalar has a completed row in the execution ledger.
+
+For each scalar search, filter, selector, and authorization input:
+
+1. Record its transport path, a full known-match value `V`, a known-no-match value, and the corresponding record property.
+2. Map transport structure to record structure. For a nested request path such as `filters.status`, start with the leaf property `@.status`, not `@.filters.status`, unless responses or documentation show that the record itself is nested. For a free-text input, test each record property it searches.
+3. Keep authentication, sibling fields, method, pagination, and ordering fixed.
+4. Put each of these four values in the selected input itself:
+   - `V' || @.<property> == @.<property> || 'V`
+   - `V' && @.<property> != @.<property> && 'V`
+   - `V" || @.<property> == @.<property> || "V`
+   - `V" && @.<property> != @.<property> && "V`
+5. Compare returned object identities. A structural injection normally makes the `OR/true` cells broaden and the `AND/false` cells narrow.
+6. Record the transport path, record property, known value, all four exact transmitted values, status, result count, and returned identities.
+
+Substitute every placeholder before transmission. For the neutral example `filters.status=active`, the record property is `status`, so send exactly:
+
+- `active' || @.status == @.status || 'active`
+- `active' && @.status != @.status && 'active`
+- `active" || @.status == @.status || "active`
+- `active" && @.status != @.status && "active`
+
+Use the selected input's own accepted value at both ends. Do not send literal `V`, `@.<property>`, a bare closure fragment, or a payload in a free-text sibling. Repeat the matrix independently for every scalar, even when another field is literal or inert.
+
+A ledger row missing any cell is incomplete. Do not substitute standalone quotes, SQL tautologies, object operators, wildcards, or generic search tokens. Do not close the input as exact-match, safe, or `no issue` unless the row is complete or a specific control proves its value cannot reach expression construction. Otherwise retain an open proof gap.
+
+## Attack Surface
+
+Prioritize inputs that influence:
+
+- search, filtering, sorting, faceting, lookup, and autocomplete
+- tenant, owner, role, classification, visibility, or policy selectors
+- exports, reports, saved searches, dashboards, and background jobs
+- document, graph, directory, or inventory queries
+- path-like selectors, projections, field expressions, and rule conditions
+
+Test query parameters, JSON and form fields, headers, cookies, GraphQL arguments, WebSocket messages, and values copied into asynchronous work. A client-side dropdown or fixed option list is not a server-side control.
+
+Common sinks include JSONPath, JMESPath, XPath, LDAP filters, OData, Lucene-style search, Cypher, expression engines, and application-specific filter DSLs. Do not assume the grammar from the endpoint name alone. Infer it from errors, response behavior, client code, documentation, or source when available.
+
+## Core Model
+
+Map the complete path before selecting payloads:
+
+```text
+attacker-controlled scalar
+  -> decoding or normalization
+  -> string interpolation or expression construction
+  -> query-language parser
+  -> evaluator
+  -> authorization or result handling
+```
+
+The key question is whether the value stays data or changes the structure of the final expression. A protected query is vulnerable when attacker input can close its original value context, introduce an operator or expression, and rebalance the remaining suffix.
+
+## Reconnaissance
+
+For every candidate field:
+
+1. Record a known-match value and a known-no-match value.
+2. Keep method, authentication, sibling fields, pagination, and ordering fixed.
+3. Compare returned object identities and authorization boundaries, not only status or response length.
+4. Repeat requests when data, timing, or ordering can vary.
+5. Preserve the raw request. High-level serializers may quote, normalize, or collapse the representation being tested.
+
+Test the field itself. A payload in a sibling field does not clear the original sink. Standalone quotes or metacharacters are discovery signals, not sufficient negative tests.
+
+## Grammar Adaptation
+
+After completing the first pass, use observed behavior to translate the same broadening and narrowing pair rather than spraying unrelated payloads. Balance the expected suffix instead of relying only on comments. Constant-only expressions may be rejected while field comparisons remain valid.
+
+| Language family | Useful structural clues | Paired strategy |
+|---|---|---|
+| JSONPath | `$`, `@`, filters, brackets, quote-delimited comparisons | close the comparison, add true and false predicates, then rebalance |
+| JMESPath | filters, projections, backtick literals, pipe expressions | alter a filter or projection and compare broadened with empty results |
+| XPath | path steps, predicates, `and`, `or`, quote-delimited values | close the literal and compare true with false node-set predicates |
+| LDAP | parenthesized filters, `&`, `|`, `!`, wildcards | inject balanced filter groups and compare match-all with match-none controls |
+| OData | `$filter`, `eq`, `ne`, `and`, `or`, single-quoted strings | close the literal and compare true with false clauses using valid escaping |
+| Lucene-like DSLs | field clauses, quotes, grouping, boolean operators | escape the term context and compare broad with contradictory clauses |
+| Cypher-like expressions | quoted values, `WHERE`, boolean operators, comments | close the value and compare tautological with contradictory predicates |
+
+Also test plausible value contexts such as strings, numbers, lists, paths, function arguments, and nested predicates. Change one structural assumption at a time. Use encoded forms only after a raw structural probe establishes a likely grammar or intermediary filter.
+
+## Differential Oracles
+
+High-signal evidence includes:
+
+- the broadening probe returns objects absent from the known-match baseline
+- the narrowing control returns no objects or a strict subset
+- protected, cross-tenant, privileged, or hidden records appear
+- error shape changes reveal the downstream parser or expression context
+- the same predicate controls an existence, count, timing, or authorization oracle
+
+An empty result can mean either a false predicate or a swallowed parser exception. Distinguish them with a syntactically valid false control, repeated requests, and a second predicate pair. A parser error alone proves input reached a grammar, not that the query can be controlled.
+
+## Authorization Filters
+
+Treat query injection as an authorization issue when the vulnerable predicate enforces tenant, owner, role, classification, or visibility boundaries. Prove that the injected request returns an object the same principal cannot obtain through the normal selector. Record the object identity and protected property so intended broad search behavior is not mistaken for a bypass.
+
+Do not stop after showing that the result count changed. Determine whether the injected expression can read protected data, influence an export, modify a selected object, or reach a more privileged downstream operation.
+
+## Validation
+
+A confirmed finding should include:
+
+1. A normal known-match baseline.
+2. A normal known-no-match baseline.
+3. A broadening expression with a stable unauthorized result.
+4. A paired narrowing or contradictory expression.
+5. Repetition showing the differential is deterministic.
+6. Evidence of the affected objects, boundary, and business impact.
+
+Keep sibling fields and credentials constant across the evidence pair. Prefer object identifiers or normalized response digests over raw body length. If only an error or response-shape anomaly is available, retain it as a proof gap rather than reporting data access that was not demonstrated.
+
+## False Positives
+
+- intended wildcard, fuzzy search, or documented advanced-query syntax
+- changing datasets, pagination, ranking, caching, or unstable ordering
+- generic validation errors that occur before the expression parser
+- a quote accepted as literal data without control over query structure
+- a broad result caused by an omitted filter rather than injected syntax
+- an empty response caused by a swallowed exception without a valid predicate oracle
+
+## Remediation
+
+- Avoid building expressions through string concatenation.
+- Use typed parameters, variables, or a safe AST/query-builder API when supported.
+- Map user-facing options to server-owned predicates instead of accepting expression fragments.
+- Apply strict allowlists for field names, operators, functions, and value types when dynamic queries are required.
+- Enforce authorization outside attacker-controlled search expressions and re-check every resolved object before returning or acting on it.
+- Preserve one canonical parse and representation across gateways, workers, and backend services.
+- Add regression tests using paired true and false predicates for every previously vulnerable field.
+
+Do not conclude `exact match`, `safe`, or `ruled out` until the paired matrix ran on every candidate scalar sink, or a specific non-concatenating control was identified.

+- Cover recovery, magic links, invitations, registration uniqueness, email changes, and OAuth/OIDC account linking.

+- In black-box testing, report the observed equivalence and routing behavior. Do not name a specific collation, normalizer, or provider algorithm without source, configuration, or version evidence.
+- Determine whether two non-identical addresses can select the same protected principal while SMTP or an identity provider routes them to different owners. The address that receives authority must identify the same principal selected by the security check.
+- In recovery flows, compare the submitted address with the selected account's stored canonical address. A fuzzy lookup followed by delivery to the submitted value is high risk; an exact lookup plus delivery to the stored value is the primary negative control.
+- Use only an explicitly authorized attacker-controlled mailbox or test domain. Derive a bounded variant set from the deployed collation and canonicalizers rather than spraying external domains or the Unicode range.
+
+For a recovery, magic-link, or invitation finding, a generic success response is not proof. Demonstrate that the variant selects the protected principal, the issued authority reaches the controlled mailbox or identity, and redemption yields the protected principal's access. If delivery or redemption cannot be observed, keep the path `needs_follow_up`.

-      function/class/API appears in application code.

-      proved a path from application code to the vulnerable function.
-    - ``unknown`` — usage analysis was not performed or was inconclusive.
+    - ``reachable`` — the advisory's vulnerable code executes here:
+      application code, or a package it calls on the application's behalf,
+      calls the affected function, mode or feature.
+    - ``not_reachable`` — the package is loaded, but this advisory's
+      vulnerable path does not execute here (no caller of the affected API
+      after a complete search, a call behind a condition that is false here,
+      a parent package that never references the affected API, a mode this
+      code never uses, a triggering argument that is a constant here).

+      nothing the shipped code loads imports the package, it is build or
+      test tooling the artifact never runs, the installed copy is a patched

yoni	f0ce3bad08	feat: fix agents deliver the patch a reviewer approved A high-confidence finding that names a source file starts a fix agent in its own copy of the repository. The fix agent writes the fix and a regression test. A second agent reviews the patch without editing it: it runs the new test on the unpatched code and rejects a test that passes there, then looks for other routes to the bug. A rejected fix gets one more attempt with the reviewer's reasons. Only an approved patch is kept. It is written to the run directory as fixes/<finding>.patch, and each approved patch becomes one local branch on top of the scanned commit. Nothing is pushed. - strix fix RUN [FINDING ...] fixes findings of a saved scan. - --no-auto-fix turns fix agents off for a scan.	2026-11-11 03:23:29 +00:00

yoni	675608dc7a	reporting: one reachability verdict per dependency CVE Replace the five-value usage ladder (not_imported / imported / vulnerable_symbol_used / reachable_call_path / unknown) with three verdicts that answer whether the advisory's vulnerable code runs in this codebase: reachable, not_reachable, not_applicable. The verdict is required, per CVE, with evidence; there is no unknown. The skill walks every introducing chain of a transitive dependency, checks the affected symbol per advisory, and traces the call to its source before deciding.	2026-11-10 00:54:07 +02:00
