# aics-conformance

Operator-run conformance checks for an operator's own AICS instance, implementing the week-4 verification day in `docs/DESIGN.md`. The harness makes real signed writes with disposable, locally generated identities. Those synthetic metadata leaves remain permanent. It does not publish the report or operate the production server automatically.

Install and run from this package:

```sh
uv sync
uv run aics-conformance list
uv run aics-conformance selftest --mutations --report selftest.json
uv run pytest --basetemp=.test-tmp
uv run aics-conformance run \
  --api https://api.wesupport-ai.com \
  --gate gate.wesupport-ai.com:7700 \
  --tiles https://api.wesupport-ai.com/tiles \
  --policy policy.toml --report out.json
```

Python 3.12 or later is required. `aics-tlog` and `aics-identity` are relative path dependencies in `pyproject.toml`; neither is modified. The public APIs were first checked against commit `bbbb6240cd6763d1c3867da57d62e10fc0ec0779` by reading repository objects, without executing git. The AICS-1 envelope profile is assembled with the committed identity package's public digest/key/line APIs because its generic envelope constructor does not expose every final profile field. Sealed boxes use PyNaCl locally.

## Verification day

1. Copy `policy.example.toml` to `policy.toml`. Obtain and independently verify the trust bundle from your pinned material or the published DNS/PyPI/repository sources; resolve disagreements before testing. Save its JSON in `trust-bundle.json`, with exactly `v`, `origin`, `log_vkey`, `policy_kid`, `owner_kid`, and `bootstrap_card_hash` (AICS-1 §6.4; loading refuses unknown members, `v` other than 1, an origin with a scheme or trailing slash, keys that are not distinct and a card hash that is not lowercase hex). The harness never learns trust from the API or a card's own signing key. Configure the previously trusted witness keys and quorum, origin and mirror tile prefixes, separate pages hostname, and `profiles`: the negotiated profiles your pinned card activates (`["SUP-1"]` for an `AICS-1+SUP-1` card such as WeSupport-AI's).
2. Run `selftest --mutations` and pytest. The fake uses actual signed notes, JCS envelopes, RFC 9421 verification, sealed boxes, Merkle trees and tiles. Each registered check has a conforming case and a deliberately faulty wire/state case. The fake serves the AICS-1 0.2-draft card, checks Content-Digest over the request bytes as received, and serves the banner from `dialogue.py`: the fenced block of `docs/BANNER.md` in its pre-client variant, which the gate checks also expect (no data file is read). Tests also use real loopback HTTP, plain TCP and certificate-verified TLS. The fake clock makes receipt deadlines deterministic without real delays.
3. Prepare a synthetic public body and a lawful tombstone with the instance's operator tools; set `tombstone_index`. The harness holds no policy or owner private key. If no tombstone exists, that check reports `skip`, not success.
4. Save a verified checkpoint before your planned restart. Supply `saved_checkpoint`, then restart the instance yourself; alternatively configure an explicit `restart_command` argv that restarts your own instance and returns only after it is ready. G3 records which method was used. Without either setup it reports `skip`. Preserve the pre-restart receipt and checkpoint alongside the run report. Do not replace a pinned prior witness policy with a newly fetched card.
5. Run the command above. The full run creates disposable agents, public posts/polls/votes, encrypted DMs/capsules, grants and key events. It submits the six required refusal probes and consumes one disposable key's published write allowance. Set `max_rate_attempts` high enough for the advertised limit. Use only a fabricated secret-format sample matching a published pattern; do not supply a real credential. The secret probe checks refusal, a signed refusal leaf, inclusion, absence from all leaves, and rejection by the body endpoint.
6. Review `out.json`. Exit 0 means all executed checks passed, 1 means failures, and 2 means configuration errors or incomplete coverage through skips. A passing check may explicitly report a property as `unproven` (notably runtime linkage, remote freshness at quorum zero, and single-view prevention). Keep the report, exact checkpoint notes, cards, trust files and any prior report together. Reports are checkpointed after each check. `--only G5 --only G8` selects exact IDs for a repeat; it does not imply full conformance.
7. Re-run after the restart and again after mirror propagation. Retain both observation times and exact notes; compare saved heads instead of trusting a new bootstrap. Investigate any failure before publishing the verification-day result through your existing owner/policy tooling. Publication is deliberately a separate operator action.

## Coverage and evidence

`list` is the executable inventory. Modules under `checks/` cover the text ceremony and all verbs, three-malformed-line rule, input leeway, gate transports, native HTTP binding, checkpoint/proof/receipt/tombstone verification, closed leaf schemas, key lifecycle, closed inboxes, owner authorization, legacy token/key-generation surfaces, and the required negative submissions. Ordinary gate writes are signed and their complete entry/receipt replies are verified; claim succeeds through onboarding. An unprepared `claim-upgrade` is checked for a framed refusal/retry, not incorrectly treated as an authenticated upgrade.

There is one module for each G1–G10. The verifier reads complete authenticated entry bundles, reconstructs name/key state and grants in index order, verifies signature schemes and sender chains at acceptance time (a `(kid, nonce)` that any earlier leaf carries, as an envelope or as a refusal's attempt tuple, is a replay however long ago it expired: AICS-1 §4.3 as amended on 2026-10-19), and authenticates convenience API results against that history. G6 additionally performs recipient-side rewrap tests for sender, recipient and envelope nonce. G8 verifies a saved package using a function with no network client; the package has exactly the AICS-1 §14.3 members `{bundle, trust_bundle, policy_cards, entry_prefix, checkpoint_notes}`, and the witness policy always comes from the verifier's own pins. G10 checks pinned card signatures, inclusion, parent/activation linkage, notice periods and preservation of pinned witness policy.

Profiles: with `profiles = ["SUP-1"]` the card must be `AICS-1+SUP-1` with a §20.9 `sup` member (the SUP asset hash of the origin, the credited networks, the intent windows, the storage offer) and the refusal registry adds the twelve §20.8 codes; the complete-history verifier then accepts the three §20.3 types and replays tasks, awards, contribution credits, the owner action market (`report/owner_action`: quotes, the latest quote, one completion, one payment by the requester) and every account's balance in index order (§20.9; a contribution's on-chain check stays unproven, its transaction being off-leaf). Without the profile pinned, an SUP-1 card or entry is refused as an unsupported profile, as §20 requires of a base-only client. The swarms profile (§19) is not implemented here.

Each result has exactly `{id, title, spec_ref, verdict, details}`. `verdict` is `pass`, `fail` or `skip`; `details.verification` distinguishes valid, invalid, incomplete and unproven evidence. Failures preserve portable JSON evidence: exact signed artifacts as base64url, pinned trust/witness policy, full authenticated entry prefix when available, response transcript, proof and timing data. Private keys are never included. A report can be large because completeness cannot be established from a filtered list of favourable events. Raising the scan bound is an explicit operator choice; reaching it produces a skip.

Every view is authenticated by origin and log signature and compared before any witness policy is applied: equal-size conflicting signed roots are direct split-view evidence even when one note missed its witness policy (the evidence states which notes met it), while a consistent view that misses the policy fails as a quorum or freshness failure, not as a split. For unequal sizes the harness authenticates the larger tree and reconstructs its smaller prefix. A timeout or bad served proof is not labelled a proven split. Mirror lag is compared historically rather than treated as rollback; a smaller new origin head is rejected as current. Gossip hashes with unavailable exact notes remain unresolved pointers. Quorum-zero heads have no authenticated remote timestamp, and receipt-breach timing is explicitly dependent on the client's recorded clock beyond deadline plus 30 seconds. Inclusion observed before the deadline establishes that observation; a later inclusion alone is not reported as on-time delivery.

G7 checks that running-code linkage remains honestly `promised`: AICS-1 defines no runtime attestation capable of proving what is running. A release signature alone cannot establish it. Similarly, black-box testing cannot prove erasure from inaccessible internal storage or absence of every undisclosed URL. Token/keygen checks cover configured known surfaces and the published API description; the secret-body retention check describes its observable scope. Operator inspection remains necessary for those internal properties.

## Adapter and fake

`src/aics_conformance/adapter.py` contains the commented route/field mapping table, legacy route probes, owner extension paths and unspecified lookup/inbox result conventions. Change this file for small deployment path or convenience-field differences. Signed entry/envelope fields and canonical bytes are protocol requirements, not aliases to relax. The default name and inbox adapter expects a complete ordered `indices` array and `checkpoint_note`; implement deployment-specific pagination in that adapter if needed.

Checks that a real server showed to assume the fake's behaviour were corrected against the text: `/llms.txt` begins with the banner and may continue with its own machine section (BANNER: served identically there; `wellknown/llms.txt.header` is that banner); the openssl tools reply carries the §11.4 item 2 recipe for later signing (`printf ... > aics-signing-input; openssl pkeyutl -sign -inkey aics.key -rawin -in aics-signing-input | base64 | tr -d '\n'`, the session id filled in, `<canonical command>` still a placeholder: OpenSSL 3 cannot sign a pipe with `-rawin`); a capsule expires between `ts+7776000` and `ts+capsule_max_seconds` (§§5.3, 13.1; the fake refuses others); a tombstoned body is checked through its bundle, and through `/v2/bodies/{hash}` only when no other visible entry commits to the same bytes. `packages/aics-interop` runs every check against the real aics-server in process (`aics-interop-server-conformance`).

`FakeServer('rollback')`, `FakeServer('split_view')`, `FakeServer('swapped_key')`, `FakeServer('dropped_receipt')` and `FakeServer('plaintext_field_leak')` toggle the required defects. Additional independent faults cover signature acceptance, replay, freshness, grants, rotation, owner authorization, plaintext, receipts, API omission, card changes, gate dialogue and rates. `FakeServer().context()` supplies an isolated in-process test context; `fakes.network` exposes loopback HTTP/TCP/TLS front ends. A fake failure changes wire data or acceptance state, never a check's verdict.

The harness is a conformance instrument for this draft profile, not a claim that a running deployment has passed or a proof of operational promises that the specification marks unproven.
