All three now follow one rule and are always visible in `report.json`, `report.md`, SARIF and the packet. The two description findings stay `support.policy_eligible: false` and `agent_action: informational`: they are never a blocker or a named review item and change no exit code, and the `insufficient_evidence` gap beside them is unchanged except that its `why` now leads with the check's catalog description ("Tool description contains a secret-like value."), as every finding-derived gap now does. Whether a lexical match may move a verdict is #1055. Migration: [STABILITY.md](STABILITY.md#secret-observations-1026). (#1026) +- **Redaction covers four more secret shapes, two more credential labels and a finding's extra fields.** `Authorization: Basic `, a PEM private-key block, a Google `AIza` key and an AWS secret access key written without a label appeared verbatim in `report.json`, `report.md`, SARIF and the packet wherever free text carried them, such as `agent.declared_purpose` or a tool name. The shared rules now redact all four (`basic_auth`, `private_key`, `google_api_key`, `aws_secret_access_key`), an `authorization`, `proxy-authorization` or `auth` labeled value after an optional scheme word (the scheme alternation the host-grant readers use; a `Digest` value to the end of its line), and `Bearer` followed by a tab. A `Basic` token counts only when it decodes to `user:password`, so prose such as `Provides Basic ReadOnly access` is neither redacted nor reported, and a 40-character run that reads as camelCase words or path segments (`getCustomerOrderHistoryForAccountV2Async`, `Sources/PaymentKit/Handlers/RefundTools2`) is not taken for an AWS key, so a SARIF alert keeps its file. The first three also raise the secret findings above and skill `SEC-SECRET-001`; the AWS shape and the labels only redact, because without a prefix or a credential label they are too common to report. `sanitize_model` now walks the extra fields of an `extra="allow"` model, so a value a check plugin attaches to a `Finding` is redacted before any writer sees it and counted in the privacy audit. `privacy_audit.rules_version` is `0.2`. A finding whose evidence held one of these shapes publishes a new fingerprint; re-save a baseline that recorded it. (#1026) - **`bootstrap` no longer runs code committed in the repository it adopts.** Each step re-entered the CLI as `python -m agents_shipgate` with the workspace as the working directory, and `python -m` puts that directory first on `sys.path`: a committed `yaml/`, `typer/`, `pydantic/` or `agents_shipgate/` package was imported and executed before `detect` read anything. The steps now run as ` -P -m agents_shipgate`, and so does every recovery command a `python -m agents_shipgate` run prints (`next_actions[].executable` is four tokens). `-P` drops only the working directory; `PYTHONPATH` and the environment still reach the child, with relative and empty `PYTHONPATH` entries anchored where `bootstrap` was started rather than resolved inside the workspace. Regression tests plant both packages, and a `yaml/` under a relative `PYTHONPATH` entry, and require bootstrap to finish without importing any of them. (#1020) - **`capability export` and the MCP `shipgate.capabilities` tool load plugins only on the opt-in.** Both passed an explicit `plugins_enabled=True` unless `--no-plugins` was given, so a read-only tool imported every installed `agents_shipgate.adapters` entry point with `AGENTS_SHIPGATE_ENABLE_PLUGINS` unset, where `scan` and `verify` imported none. They now honour the same opt-in, `--no-plugins` still wins, and the lock's `source.plugins_enabled` records the value that took effect (`false` by default, which moves `source_set_hash`). An adopter whose lock includes tools read by a third-party adapter sets the variable for `capability export`, as `scan` already required. (#1020) - `docs/trust-model.md` lists every process Shipgate starts — the Git plumbing behind `verify`, `check`, `diff` and the Claude Code hooks, workspace discovery, `bootstrap`'s self-invocation, fixture Git, the `authorization execute` HTTPS push and the native prover — instead of saying it shells out only for Git discovery. `tests/test_adapter_static_only.py` fails when a spawn site is added, removed or moved without that table changing, when a `-m agents_shipgate` argv lacks `-P`, and now also on `asyncio.create_subprocess_*`.
