* feat(harness): add deterministic tool receipts with model-visible ledger Stamp an immutable per-call fact record (tool name, status, args/output hashes, byte count, timestamp) onto every tool result via a new ToolReceiptMiddleware, and inject the derived receipt ledger (r1..rN) into the model context so subagent reports can cite executed actions. - tool_receipt.py: receipt core (make/extract/render), newest-first budget eviction, ids derived from the append-only message stream - ToolReceiptMiddleware: stamps ToolMessages directly or inside Command-wrapped results; hidden ledger injection mirrors DurableContextMiddleware; sits between ToolProgress and ToolErrorHandling with a build-time ordering guard - config: new verification section (receipts on, judge off), config version 32 -> 33 with example/helm/docs updates * feat(harness): split receipt rendering from stamping; address PR review Review fixes (PR #4659): - output_sha256 now uses sort_keys=True for structured content, matching the order-invariant args fingerprint - stamping failures log at warning (silent ledger gaps would corrupt citations); tool execution remains never blocked - _insert_after_leading_system_messages extracted to shared public message_utils.insert_after_leading_system_messages; both middlewares depend on it instead of a private cross-module helper - code comments in English RFC #4651 revision-2 alignment: - receipts_render_mode config ('always' | 'delegation_only'): subagent chains always render the ledger (citations are produced there); the lead chain renders only while processing subagent results, removing the always-on token tax from ordinary turns - receipts gain bounded args_preview/output_preview (<=200 chars, tail for output) so later typed claim bindings (tests_passed) can anchor to a specific recorded execution * docs(harness): state receipt freshness caveat and vocabulary layering in module docstring * merge: upstream/main — resolve AGENTS.md split, bump config_version to 34, drop unused receipt previews - backend/AGENTS.md: take upstream's slimmed root guidance (#4799); move the ToolReceiptMiddleware chain entry into agents/middlewares/AGENTS.md and the verification.* hot-reload mention into config/AGENTS.md - config.example.yaml + helm values/README: config_version 33 -> 34 so existing v33 configs get the outdated-config prompt (review: willem-bd) - tool_receipt.py: drop args_preview/output_preview — no Layer 1 consumer reads them; re-add with the Layer 2 claim-binding consumer (review: willem-bd) * docs(harness): cover receipt id renumbering after compaction in module docstring Positional display ids are stable only while history is append-only; compaction drops ToolMessages and the survivors renumber, so Layer 2 citation verification must resolve [rN] against the ledger as of the citing turn (review: willem-bd, doc-only). * chore(config): bump config_version to 35 main reached 34 via #4780 without the verification section; publishing the new schema at the same number would silently skip the outdated-config prompt for configs synced from main in that window (review: willem-bd). * fix(skills): restore errno import dropped upstream in #4830 upstream/main adf6c422 uses errno.ENOTDIR in the drift guard but removed the import, so the PR merge ref fails lint-backend (F821). * fix(harness): harden tool receipts against forgery and turn-scope delegation_only Address willem-bd's pre-merge review on #4659: 1. Untrusted receipt metadata: the gateway now strips the server-owned deerflow_tool_receipt key from external input messages; stamping always overwrites any tool-supplied value instead of preserving it; and extract_tool_receipts validates persisted receipt shapes (required typed fields, unknown keys ignored) so malformed entries are skipped instead of crashing render or passing as runtime-stamped evidence. 2. delegation_only no longer sticks on: _should_render now scopes the subagent_status scan to the current turn (messages after the latest genuine user message), so an old completed delegation stops rendering the ledger on later ordinary turns. The genuine-user predicate moves to message_utils.is_genuine_user_message, shared with input sanitization. * fix(harness): stamp receipts outside short-circuiting tool middlewares Address willem-bd's review on #4659: ToolReceiptMiddleware was registered inside Guardrail/SandboxAudit/ReadBeforeWrite/ToolProgress, each of which can return a ToolMessage without invoking its handler — blocked calls (e.g. a read-before-write-denied write_file) never got a receipt, silently gapping the ledger on a default-enabled path. SandboxAudit additionally rebuilds medium-risk results, dropping an inner stamp. ToolReceiptMiddleware is now the outermost wrap_tool_call layer in the runtime tail. Normal results still carry deerflow_tool_meta (stamped by ToolErrorHandling on the inner return path); short-circuit messages self-stamp meta or fall back to message.status. The new invariant is declared as ordering constraints in deerflow.extensions.ordering, with composed-chain regression tests for a blocked write and a warn-rebuilt bash result.
