The approval gate for asset targets now decides. It is opt-in per task and
per conversation (target_gate, default off). With the flag off nothing is
extracted, resolved, read or written, and every branch of the hook behaves as
before. No UI.
Extraction and normalisation (1.5)
- intercept.NormalizeTarget: lower case, trailing dot, userinfo, IPv6
brackets, IPv4-mapped IPv6, decimal / hex / octal / short IPv4, percent-
encoded host, punycode; port explicit, else the scheme default, else 0.
- intercept.ExtractTargets: WebFetch url exactly; Bash, shell_open, Monitor
(command) and shell_send (text) with the command-string rules (URL with a
scheme, IP, IP:port, host:port, CIDR; a bare name is not a target); every
string of the input for MCP tools, custom tools and any tool the gate does
not know. ExecuteExtraTool is unwrapped to the inner tool. The platform's
domain tools, the file tools and web_search have no target.
- The fields are decoded as the tools decode them (key case, last duplicate),
and a URL authority that reads differently quoted and unquoted yields both
readings.
Resolver, exemptions, gate decision (1.6)
- Resolver interface, system implementation (A and AAAA), 3 s per lookup,
positive answers cached 10 s per host with collapsed lookups, failures and
empty answers never cached, always fresh when a request is raised.
- Exemptions are exact host + port. Derived from the configuration (LLM
gateways, search backend in use, platform proxies): computed on every call,
never resolved, never voided. Stored (settings key
target_gate_exempt_hosts, seeded once with the package sources): resolved,
and void when any address is private, loopback, link-local, unspecified,
unique-local, multicast or a metadata address. An entry in both origins
counts as derived. A stored IP literal that can never be exempt does not
apply.
- GET / PUT /api/target-gate/exemptions and GET .../history. A change is
validated (ValidateExemptionHost on the normalised host) and appended to
target_gate_exemption_log in the transaction that stores it.
- Interceptor.CheckTargets: asset block rules (global and of the task) on the
name and its addresses, exemptions, resolution, pin lookup. A (host, 0) pin
covers every port; a (host, 443) pin covers 443 only and never a target
without a declared port; two pins are never merged. At most 5 unpinned
targets per call. Codes: TARGET_RULE_BLOCKED, TARGET_RESOLVE_FAILED,
TARGET_TOO_MANY, TARGET_GATE_UNAVAILABLE; none opens a request.
- With the upstream egress proxy set every pin is name-only at call time,
whatever name_only_effective says in its row.
- An approval never pins zero addresses: the pin writer refuses a request
that displays none (db.ErrTargetPinEmpty, 422 on the decide endpoint, the
row stays pending) and RequestTargets does not open one.
- Every block, and the first use per process of each exemption and of each
pin version, is a decided row (decided_by system, decision_source target).
The gate in the hook (1.7)
- guard.applyIntercept: a deny by a rule or by the judge blocks first, before
any target request exists; then CheckTargets; an allow is logged as before
and does not satisfy the gate; an ask and an unpinned target share one
request, and the classic ask is raised only when it was not merged. The
call is checked again after the decisions, at most three passes.
- The gate applies to every tool of a gated session, enabled for rules or
not, and to the target-only guard of the planner and the main agent, which
still records blocks only.
- Target blocks have their own model-facing text, built from the code and the
reason of the result.
Not in this change: rendered targets of custom tools (1.8) and redirect
targets (1.9). Subprocess paths stay advisory; the TestBypass_* tests document
what the gate does not see.
Storage, flag and request path of the approval gate for asset targets. The
gate itself is not wired into the tool hook yet (steps 1.5 to 1.7): with this
change nothing is extracted, resolved or blocked, whatever the flag says.
Schema and store (1.2)
- tasks.target_gate, conversations.target_gate (default false).
- intercept_pending.target_key and a partial unique index: one open request
per scope (task or conversation) and host:port.
- target_pins (no foreign keys: a pin outlives its task, its conversation and
its request row) and target_gate_exemption_log. All DDL is idempotent; no
CHECK constraints; the cascade on intercept_pending.conversation_id stays.
- db/target_pins.go: pin lookup with port precedence, list, revoke,
find-or-create of a request, and ResolveTargetRequest, which settles the
row, supersedes the old pin and writes the new version in one transaction.
- Deleting a task or an archive stub revokes its pins and settles its open
target requests in the delete transaction. DeleteConversation and
DeleteConversations revoke the pins of the removed conversations in the
same transaction as the delete.
Opt-in flag (1.3)
- Per task through the create and metadata-patch paths, per conversation
through create and patch; exposed in the task DTO. A retest conversation
takes the flag of the finding's task, never its pins. A spawned task starts
with the gate off.
- The task flag is atomic and read on every call through TargetScope.Enabled.
TargetScope now carries the Interceptor that owns the gate.
Request, wait, decide (1.4)
- pendingManager keeps a list of waiters per request; resolve wakes all.
- RequestTargets: find-or-create per target, one card per request, wait on
channel, poll, context and wait bound. A plain request is never settled by
a call that leaves. A request merged with an ask is bound to its creating
call and a timeout never allows it.
- Decide records the approver (subject of the session token) and the remote
address for every human decision, classic asks included. On a target
request "allowed" pins the displayed addresses; that is the only writer of
pins.
- A request raised while the global egress proxy is set says the approval is
name-only and its pin is stored with name_only_effective.
- Routes: GET/POST .../target-pins and .../target-pins/{pid}/revoke under
/api/tasks/{id} and /api/conversations/{id}; decision_source=target filter.
- ValidateExemptionHost: an exemption written as an IP literal may be private
unicast, never loopback, link-local or metadata, unspecified or multicast.
Add intercept_pending.decided_by (human | rule | model | system; empty while
pending or for rows decided before the column existed). Approval semantics are
unchanged: only the actor is recorded.
- rule-matched and model-judged rows written by CreateDecidedIntercept record
rule or model;
- ResolveIntercept takes the actor explicitly and rejects any other value
before touching the database;
- Decide (human allow/deny) records human; timeouts and work-cancelled
denials record system. Work-cancelled is a system refusal, not a human one.
- decided_by is exposed on the pending and approval records and filterable
with decided_by=human|rule|model|system (anything else is a 400).
- Legacy rows show decision_source as their actor when decided_by is empty.
The filter uses the stored column only, so decided_by=model cannot match
older human decisions or timeouts.
- Archive restore fills decided_by for archives that predate the column, and
marks a restored pending row as system.
Comments, doc comments, UI labels, log and error messages, LLM prompt
strings, markdown docs, test data and assertions. Identifiers, enum
keys, routes, placeholders and code structure are unchanged.
Notes:
- docs/漏洞流量证据.md renamed to docs/vulnerability-traffic-evidence.md
- tests that exercised CJK specific handling (GBK zip names, Chinese
full text search) now use ASCII equivalents; go build passes and the
test suite matches the pre translation baseline (remaining failures
need a PostgreSQL DSN and fail identically on the original)
- frontend mention syntax now uses English kinds (finding, asset, ...)
matching the backend, chat mentions tests pass
