From 6f3a59e2057362cc1e614d4ce7e7bcdf10b009c1 Mon Sep 17 00:00:00 2001 From: BaaRai <130491490+BaaRai@users.noreply.github.com> Date: Thu, 12 Nov 2026 20:16:23 +0100 Subject: [PATCH 1/2] Coverage ledger: record examined, ruled-out and untested risk classes Workers record per (surface, risk_area) outcomes with the new record_coverage tool (reported, no_issue_found, ruled_out, not_applicable, needs_follow_up). Gaps are needs_follow_up entries, entries missing their required evidence or reason, and goal vulnclass values with no entry (unrecorded_risk_class), so an absent finding never reads as a clean target. Completeness marks timeout, budget wrap-up, pause, abort and running tasks as incomplete with a caveat. Surfaced in the planner context (one line per round, full gap list on the timeout/budget wrap-up round), GET /api/tasks/{id}/coverage, the coverage card and the Markdown report. Follows coverage_enabled; no new env var. --- agent/budget.go | 2 +- agent/coverage_ledger.go | 106 +++++++ agent/coverage_ledger_test.go | 142 ++++++++++ agent/planner.go | 3 + agent/tools.go | 2 +- agent/tools_insert.go | 2 + agent/worker.go | 2 +- db/coverage_ledger.go | 260 ++++++++++++++++++ db/coverage_ledger_test.go | 153 +++++++++++ db/schema.sql | 32 +++ db/task_scope.go | 3 + intercept/target_extract.go | 2 +- report/report.go | 13 + report/report_test.go | 34 +++ server/engine_timeout.go | 5 +- server/server.go | 11 +- .../tasks/detail/_tabs/overview-tab.tsx | 20 +- web/src/lib/api.ts | 3 + 18 files changed, 788 insertions(+), 7 deletions(-) create mode 100644 agent/coverage_ledger.go create mode 100644 agent/coverage_ledger_test.go create mode 100644 db/coverage_ledger.go create mode 100644 db/coverage_ledger_test.go create mode 100644 report/report_test.go diff --git a/agent/budget.go b/agent/budget.go index 82e6573..f22028e 100644 --- a/agent/budget.go +++ b/agent/budget.go @@ -212,7 +212,7 @@ func (m *IntentMeter) Finish() { // BudgetWrapupBlocks reports whether a worker tool is refused once its budget is // exhausted: all but the write-back tools, so the run records facts and stops. func BudgetWrapupBlocks(tool string) bool { - return tool != "record_fact" && tool != "insert_assets" && tool != "report_finding" && tool != "update_finding_report" + return tool != "record_fact" && tool != "insert_assets" && tool != "report_finding" && tool != "update_finding_report" && tool != "record_coverage" } // WorkerBudgetWrapup is returned in place of a refused tool call. diff --git a/agent/coverage_ledger.go b/agent/coverage_ledger.go new file mode 100644 index 0000000..69bac37 --- /dev/null +++ b/agent/coverage_ledger.go @@ -0,0 +1,106 @@ +package agent + +import ( + "context" + "encoding/json" + "fmt" + "strings" + + "github.com/Autumn-27/artex/db" + actool "github.com/Autumn-27/norma/tool" +) + +// recordCoverage writes one coverage-ledger entry (db/coverage_ledger.go).
