test(compaction): drop comment restating the test name

fix(compaction): fall back to reasoning text when the summary has none
A reasoning model can spend the whole summary output budget thinking and return only a reasoning item. _extract_text read only output messages, so compaction logged 'summary returned no content' and the agent failed. Use the reasoning text, with a warning, when there is no output text.

-
-Some provider parameters go in the request body rather than a header, and
-Strix has no dedicated setting for them. Set them with `LLM_EXTRA_BODY` as a
-JSON object — they are merged into the body of every request to the model. For example, to

-```bash
-export LLM_EXTRA_BODY='{"service_tier":"flex","safety_identifier":"9f86d081884c7d65"}'

-
-Fields aren't validated, so use only fields your provider accepts, and don't
-set fields Strix already sends, such as `model`, `messages` or `stream`.
-
 For endpoints behind a private CA, point Strix at your certificate bundle with
 the standard `SSL_CERT_FILE=/path/to/ca-bundle.pem` — never disable TLS
 verification against a real endpoint.

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

 ## Setup

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

 ```bash
-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"

 - Keep going until you find something that matters
 - 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.

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. Before `finish_scan`, the root agent calls `list_coverage(outcome="needs_follow_up")` and follows up every row it returns: it assigns the outstanding work to a subagent that moves the existing entry with `update_coverage` to its real outcome, and a row stays `needs_follow_up` only when it is genuinely blocked, with the blocker stated in its evidence.

The root agent reconciles all of it via `list_coverage` before `finish_scan`.
 - 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.
 - Before filing any report, run the counterevidence pass: argue the strongest case AGAINST the finding, record what you found in the `counterevidence` field, set `confidence` honestly (a static-only trace you couldn't execute is at best `medium`), and state what evidence would change the severity. See the counterevidence and severity-calibration knowledge above.
- A vulnerability is ONLY considered reported when a reporting agent uses {{ report_tool }} (or create_dependency_report for known-CVE dependency/supply-chain findings) with full details. Mentions in agent_finish, finish_scan, or generic messages are NOT sufficient
- Reporting and fixing are ONE step, not two: when source is available, the reporting agent derives the concrete fix and files it INLINE via {{ report_tool }} (`code_locations` with `fix_before`/`fix_after` + `fix_pr_body`) — the report is not complete without it. Do NOT report first and then spawn a separate downstream agent to re-derive and re-apply the same patch; that just re-does the analysis and wastes tokens. (Do not silently patch a finding WITHOUT filing a report — the report, with its embedded fix, is the deliverable.)
- DEDUPLICATION: The {{ report_tool }} tool uses LLM-based deduplication. If it rejects your report as a duplicate, DO NOT attempt to re-submit the same vulnerability. Accept the rejection and move on to testing other areas. The vulnerability has already been reported by another agent. If your evidence proves more than the finding it matched (a working exploit where that one had only a static trace, a chain that raises the impact), revise that finding with update_vulnerability_report using the duplicate_of id — never re-file it.

 - HTTP EVIDENCE: a finding you validated through the proxy is not fully filed until `http_exchange_ids` carries the proxy request ids of the exchanges that prove it — the request that triggers the vulnerability plus the baseline/control request it differs from (an unauthenticated success next to the authenticated one, the payload response next to the benign one). Copy the ids exactly as `list_requests`/`view_request` show them, never invent or guess one, and never omit the field to bypass validation. Leave it out only when there is no captured HTTP exchange at all (static-only code findings, dependency CVEs). If you filed before the proving exchanges existed, attach them afterwards with update_vulnerability_report. Without the ids, the finding ships as prose nobody can replay.
 - REVISING A FINDING: use update_vulnerability_report (report id + the fields you want to replace + update_reason) when you learn something a finding already on file does not carry — you built the PoC after filing it, a chain raised its impact, further testing weakened it, or its counterevidence/remediation/code locations were wrong. Editing a finding needs no duplicate verdict, and it is always better than filing a second report for the same issue. Read the finding first with get_report, and pass only the fields that change.
 - WITHDRAWING A FINDING: when re-testing proves a finding you filed is not a vulnerability at all — the exploit only worked because of your own test setup (a mixed-up session, a self-inflicted state change, a misread response), the behaviour is intended, or the control is in fact enforced — delete it with delete_vulnerability_report (report id + delete_reason). Never leave a disproved finding on file as a zero-CVSS, "retracted", or "false positive" report, and never rewrite its text into a note saying it was wrong: a report that exists is read as a finding. Delete is for a finding that does not exist; a finding that is real but weaker than filed is revised, not deleted.

Write a note for a durable cross-agent fact that is not a finding and not coverage — a working credential set, a discovered endpoint inventory, an enumerated tenant list, a rate-limit quirk the next agent needs. `update_note` to keep a living inventory current; `delete_note` only for something now wrong or superseded.

 - SPAWN WORK — `create_agent`: delegate a focused subtask to a specialist child (see the multi-agent rules below for when to spawn and how to scope it). Give it the target to model against and what is already known.
 - TRACK CHILDREN — `view_agent_graph`: your live map of every agent and its status. Call it before spawning (to confirm no existing agent already covers the scope) and before finishing (to confirm no child is still running).
 - STEER CHILDREN — `send_message_to_agent`: send a running child new information, a course correction, or a request to wrap up, without killing it. Use it to answer a child's question or narrow its scope mid-run.
 - BLOCK ON CHILDREN — `wait_for_agents`: block until named children report back when your next move genuinely depends on their results. If you can keep making progress in parallel, keep working instead of waiting.
 - CANCEL CHILDREN — `stop_agent`: gracefully cancel a child whose work is redundant, misdirected, or no longer needed. Prefer `send_message_to_agent` to redirect a child that is merely off-track; reserve `stop_agent` for work that should not continue at all.
- FINISH — subagents call `agent_finish` (with `open_items=[...]` for anything left unresolved); the root agent calls `finish_scan` exactly once, only after every child is wrapped up and coverage is reconciled. `agent_finish`/`finish_scan` are handoffs, not reporting channels — a vulnerability is reported only via `{{ report_tool }}`/`create_dependency_report`.

-"""Keep replayed tool-call arguments valid JSON.

-A model occasionally emits a tool call whose ``arguments`` string is not a
-JSON object (truncated, unbalanced, empty). The call itself fails safely: the
-tool reports the parse error and the run continues. But the raw string is
-recorded in the session as-is, and strict OpenAI-compatible servers (vLLM,
-SGLang, ...) validate every assistant tool call in the request, so from then
-on each turn is rejected with ``Assistant tool call function.arguments must
-be valid JSON`` and the agent can never recover. Rewriting the replayed
-arguments to a JSON object that carries the original text keeps the history
-valid while the model still sees what it sent.

- `/opt/opengrep-rules` holds the full ruleset, one directory per language (`python`, `javascript`, `typescript`, `go`, `java`, `php`, `ruby`, …) plus `generic/secrets`, `dockerfile`, `terraform`, `yaml`, and `strix` (Strix-authored rules, e.g. GitHub-owned actions not pinned to a commit SHA)
- Framework rules sit under the language (`python/django`, `python/flask`, `javascript/express`, …)
-
-High-signal flags:
- `--config <path>` rule file or directory; repeat for several
- `--taint-intrafile` intra-file inter-procedural taint (follows data across functions in one file)
- `--json` / `--sarif` output format
- `--output <file>` write findings to file
- `--severity <level>` filter by severity (`INFO`, `WARNING`, `ERROR`)
- `--error` return non-zero exit when findings exist
- `--quiet` suppress progress noise
- `--jobs <n>` parallel workers
- `--timeout <seconds>` per-rule, per-file timeout
- `--exclude <pattern>` / `--include <pattern>` path filters
- `--exclude-rule <rule_id>` suppress specific rule
- `--baseline-commit <sha>` only report findings introduced after baseline
-
-Agent-safe baseline for automation:
-`opengrep scan --config /opt/opengrep-rules --taint-intrafile --json --output opengrep.json --quiet --jobs 4 --timeout 20 /workspace`
-
-Common patterns:
- Full bundled scan:
-  `opengrep scan --config /opt/opengrep-rules --json --output opengrep.json --quiet /workspace`
- High-severity focused pass:
-  `opengrep scan --config /opt/opengrep-rules --severity ERROR --json --output opengrep_high.json --quiet /workspace`
- SARIF output:
-  `opengrep scan --config /opt/opengrep-rules --sarif --output opengrep.sarif --quiet /workspace`
- Language- or framework-specific rules:
-  `opengrep scan --config /opt/opengrep-rules/python --config /opt/opengrep-rules/generic/secrets --json --output opengrep_python.json --quiet /workspace`
- Scoped directory scan:
-  `opengrep scan --config /opt/opengrep-rules --json --output opengrep_api.json --quiet /workspace/services/api`
- Custom rule:
-  `opengrep scan --config ./rules/my-rule.yaml --json --output opengrep_custom.json --quiet /workspace`
-
-Critical correctness rules:
- Always provide an explicit `--config` from `/opt/opengrep-rules` or a local rule file. Registry shorthands (`p/...`, `auto`) fetch rules from the network; do not use them.
- Opengrep has no telemetry; there is no `--metrics` flag, and passing one fails the scan.
- Prefer `--json --output <file>` or `--sarif --output <file>` for machine-readable downstream processing. JSON keeps `paths.scanned` and `results[].path`.
- Keep the target path explicit; use an absolute or clearly scoped workspace path instead of `.` when possible.
-
-Usage rules:
- Start with the full `/opt/opengrep-rules` set unless the task clearly calls for a narrower language or framework directory.
- Add `--taint-intrafile` for injection-class hunting (SQLi, command injection, SSRF, path traversal) in supported languages.
- Use `--quiet` in automation to reduce noisy logs.
- Use `--jobs` and `--timeout` explicitly for reproducible runtime behavior.
- `PartialParsing` errors on templates are normal; they do not invalidate the run.
-
-Failure recovery:
- If scans are too slow, narrow the target path and the rule directories before changing engine settings.
- If scans time out, increase `--timeout` modestly or lower `--jobs`.
- If output is too broad, scope `--config`, add `--severity`, or exclude known irrelevant paths.

 Distinguish HTML-string input from live DOM objects sanitized with `IN_PLACE`. Resolve the deployed DOMPurify build and check relevant upstream advisories; a controlled observable `nodeName` is one live-node bypass mechanism. Trace same-origin foreign nodes or `adoptNode()` into this mode before selecting the bypass ([example advisory](https://github.com/cure53/DOMPurify/security/advisories/GHSA-x4vx-rjvf-j5p4)).

-### Scriptless HTML Injection
-
-Do not require JavaScript execution before you report HTML injection. Prove that the browser creates attacker-controlled markup and a concrete security effect.
-
-Test base or form target changes, external requests, deceptive content, DOM clobbering through `id` or `name`, and dangling markup. Report XSS only when you prove a script-capable execution path. Do not dismiss HTML injection only because CSP blocks scripts.
-
-### Unicode Normalization
-
-Test normalization only when the target performs it. NFKC can fold fullwidth delimiters such as `＜` and `＞` into HTML syntax.
-
-Map validation, normalization, sanitization, encoding, and parsing in order. Start with the harmless canary `＜h1 id="strix-nfkc"＞marker＜/h1＞`.
-
-Report a bypass only when normalization creates dangerous syntax that reaches an unprotected sink. Load `semantic_confusion` when components interpret the value differently.
