From 31eaf7b63c5f87d2d2196d342c8ae3028221b502 Mon Sep 17 00:00:00 2001 From: Grad Date: Thu, 13 Aug 2026 22:37:31 +0300 Subject: [PATCH 1/4] Implement Grad: the agent, its CLIs, the gates, and the interface Implements HANDOFF.md. The spine is the rule that anything which spends money, destroys work, or must be true before the fact is enforced by a program that refuses to proceed, never by a sentence in the system prompt. core/ the machinery the CLIs share, so no single tool can forget a rule: one locked JSONL write path, the resolved-submission hash, the four submit gates, the smoke caps, event-folded run records, and the CLI contract (--json, distinct exit codes, errors that state the fix). tools/ eight CLIs invoked over Bash: the retrieval funnel, LaTeX ingest, the persistent kernel, preflight, the two submitters, the ledger, and quota accounting. agent.py deny-by-default permission configuration plus the deny probe, since the mode's semantics have changed between SDK releases and the whole safety story rests on them. ui/ NiceGUI, with the four widgets that surface state which is otherwise invisible: preflight, expectation vs outcome, quota, funnel. 85 tests, no network and no SDK required. The gate tests run against a real ledger in a temp workspace rather than mocks -- a mock of a gate proves nothing about the gate.

Relational predictions produce in_range=None, not False, so unjudged_deviations() dropped them from pending() -- meaning the prediction type §7 explicitly prefers was the one that quietly stopped being judged once the agent moved past collect's immediate 'next'. The predicate now matches collect's: not confirmed in range, not yet judged. Same for a non-numeric result and for a run that reported nothing for the predicted quantity. jobs.py built a --help string from credentials.status(), and argparse setup runs at decoration time, so importing the module for any subcommand read all four entries out of Windows Credential Manager. Now a static tuple of names, with a test that fails if importing any tool touches the store. The msvcrt fallback locked a byte range at the current file position, and an append handle opens at EOF -- so as the ledger grew, writers locked different bytes and none excluded any other, while _unlock's mismatched seek(0) swallowed the resulting OSError. portalocker is not installed on this machine, so this was the live path. The obvious test for that last one has no teeth: O_APPEND already makes a single small write atomic, so a multi-process append test passes with the lock broken. Verified by reverting the fix. The added test exercises the primitive instead -- one process holds the lock and grows the file, a second must fail to take it -- and does fail against the bug. 91 tests, up from 85.

The rest were real. The ones that mattered most: Gate integrity. `from pkg import mod` and `from . import mod` were never resolved, so editing those modules left the submission hash unchanged and an old preflight record kept passing -- the exact invalidation gap the import graph exists to close. Tag stripping cut at the first colon, so a registry port turned `registry.local:5000/org/name:tag` into `registry.local@sha256:...`. Binding an expectation is now re-checked inside the append lock, since the gate runs before the write and two submitters could both pass it. gpu.py now finalises a run whose staging or launch failed, instead of leaving an in-flight estimate that consumes the ceiling and later blocks submissions as stale. Data integrity. Embeddings are ordered by their upstream index and a short batch is refused: the caller zips them against chunk ids, so position is identity, and a truncated write would pair chunk k with another chunk's vector undetectably. `reembed` computes before it destroys, so a failure mid-way no longer leaves the index with chunks and no vectors. The derived index keeps in_range tri-state, so NULL (needs a verdict) stays distinct from 0 (out of range). Security. Notebook HTML renders in a sandboxed iframe rather than the app origin. The browser fallback binds 127.0.0.1 explicitly. `trace` accepts only the slug alphabet it mints. scrub_environment removes the GRAD_* credential fallbacks, which exist for CI and have no business surviving into the agent's environment. Correctness of the safety story itself. The deny probe now takes its verdict from the hook's own record of what it refused, not from substrings in a transcript -- the deny message contains gpu.py and a model narrating success can say denied, and a false `denied` is the one outcome that probe must never produce. The Windows lock moved to a sentinel byte past the data: a lock over live data denies reads too, which is what surfaced when the new atomic precondition tried to consult the file it was locking. 130 tests, up from 91.
