# AGENTS.md — amduat-api
This repo hosts the **API/daemon surface** for Amduat.
## Scope
- `vendor/amduat/` is the **core C substrate** (ASL/PEL/TGK libs, codecs, adapters, reference CLIs).
- This repo should keep `amduatd` **thin**: HTTP transport, request parsing, auth, and mapping to core library calls.
- Do **not** re-implement substrate semantics here; add features to the core repo and call into it.
## Build
- Configure: `cmake -S . -B build`
- Build: `cmake --build build -j`
## Run (local Unix socket)
- Prepare store root (from core tools): `vendor/amduat/build/amduat-asl init --root .amduat-asl`
- Start daemon: `./build/amduatd --root .amduat-asl --sock amduatd.sock`
## Submodule workflow
- Update core to recorded commit: `git submodule update --init --recursive`
- Bump core commit:
- `git -C vendor/amduat fetch`
- `git -C vendor/amduat checkout <commit-or-tag>`
- `git add vendor/amduat && git commit -m "Bump amduat core"`
## API principles
- Single daemon instance = single ASL store root.
- Local auth = filesystem permissions on the socket (no extra auth yet).
- Prefer streaming/batching endpoints (`missing`/`pack`) before adding complex higher-level APIs.
- Keep the on-wire contract versioned (`/v1/...`) and additive.

# amduat-api
# amduat-app-next (Scaffold)
`amduat-api` builds `amduatd`, a minimal HTTP server over a Unix domain socket that exposes Amduat substrate operations for a **single ASL store root**.
Starter project scaffold for building an app against `amduatd` v2.
## App Developer Handoff
## Included handoff assets
For a compact, implementation-focused guide for external app teams, use:
- `docs/v2-app-developer-guide.md` (compact app guide)
- `contracts/amduatd-api-contract.v2.json` (machine contract)
- `scripts/graph_client_helpers.sh` (reusable shell helpers)
- `docs/v2-app-developer-guide.md`
- `registry/amduatd-api-contract.v2.json` (machine-readable contract)
## Quick start
## Build
1. Configure environment:
```sh
cmake -S . -B build
cmake --build build -j
cp config/env.example config/env.local
```
To build without the embedded UI:
2. Start a local daemon:
```sh
cmake -S . -B build -DAMDUATD_ENABLE_UI=OFF
./scripts/dev_start_daemon.sh
```
`dev_start_daemon.sh` initializes the store for the selected backend and, when
`STORE_BACKEND=index`, runs a quick startup write probe. If index writes are
unhealthy, it first tries a one-time index store repair (backup + re-init) and
then falls back to `fs` if still unhealthy (configurable via
`INDEX_BACKEND_PROBE`, `INDEX_BACKEND_REPAIR`, and `INDEX_BACKEND_FALLBACK` in
`config/env.local`).
When the UI is enabled (default), `/v1/ui` serves the same embedded HTML as before.
## Core dependency
This repo vendors the core implementation as a git submodule at `vendor/amduat`.
3. Run startup checks against the daemon socket:
```sh
git submodule update --init --recursive
./scripts/bootstrap_check.sh
```
## Quickstart (local)
Initialize a store:
4. Run sample idempotent batch ingest:
```sh
./vendor/amduat/build/amduat-asl init --root .amduat-asl
./scripts/ingest_example.sh
```
Run the daemon (fs backend default):
5. Run sample changes consumer (recommended):
```sh
./build/amduatd --root .amduat-asl --sock amduatd.sock
./scripts/v2_app.sh consume-changes
```
Run the daemon with the index-backed store:
## v2 Vertical Slice CLI
Use the integrated v2 app flow wrapper:
```sh
./build/amduatd --root .amduat-asl --sock amduatd.sock --store-backend index
./scripts/v2_app.sh startup-check
./scripts/v2_app.sh ai-vertical-slice
./scripts/v2_app.sh ai-vertical-slice --skip-evals
./scripts/v2_app.sh ai-vertical-slice --auto-start-daemon
./scripts/v2_app.sh ai-agent 'doc-ai-1' 'What domain is doc-ai-1 in?' 'ms.within_domain'
./scripts/v2_app.sh ai-agent --json --require-evidence --max-steps 3 'doc-ai-1' 'What domain is doc-ai-1 in?' 'ms.within_domain'
./scripts/v2_app.sh ai-check
./scripts/v2_app.sh ai-generate 'Summarize retrieval behavior in one sentence.'
./scripts/v2_app.sh ai-generate --json 'Summarize retrieval behavior in one sentence.'
./scripts/v2_app.sh ai-answer 'doc-1' 'What topic is doc-1 in?' 'ms.within_domain'
./scripts/v2_app.sh ai-answer --json 'doc-1' 'What topic is doc-1 in?' 'ms.within_domain'
./scripts/v2_app.sh ai-answer --json --require-evidence 'doc-1' 'What topic is doc-1 in?' 'ms.within_domain'

./scripts/v2_app.sh consume-changes --once
./scripts/v2_app.sh retrieve 'doc-1' 'ms.within_domain'
./scripts/v2_app.sh tombstone '<edge_ref>'
```
Note: `/v1/fed/records` and `/v1/fed/push/plan` require the index backend.
AI lane notes:
## Federation (dev)
- Plan and scope guardrails: `docs/ai-plan.md`
- Deterministic seed payload: `ai/fixtures/seed_batch.json`
- Agent loop checkpoints: `ai/runs/agent-run-*.json` (updated at start, each planner step, and completion with `status` + timestamps)
Federation is opt-in and disabled by default. Enabling federation requires the
index-backed store and explicit flags:
Run integration coverage (requires running `amduatd` + `jq`):
```sh
./build/amduatd --root .amduat-asl --sock amduatd.sock --store-backend index \
--fed-enable --fed-transport unix --fed-unix-sock peer.sock \
--fed-domain-id 1 --fed-registry-ref <registry_ref_hex>
./tests/integration_v2.sh
```
Flags:
- `--fed-enable` turns on the coordinator tick loop.
- `--fed-transport stub|unix` selects transport (`stub` by default).
- `--fed-unix-sock PATH` configures the unix transport socket path.
- `--fed-domain-id ID` sets the local domain id.
- `--fed-registry-ref REF` seeds the registry reference (hex ref).
- `--fed-require-space` rejects `/v1/fed/*` requests that do not resolve a space.
`X-Amduat-Space` is honored for `/v1/fed/*` requests the same way as other
endpoints. If `--space` is configured, unix transport requests will include the
same `X-Amduat-Space` header when contacting peers.
### Federation cursors
Federation cursors track deterministic, auditable sync checkpoints per
`(space, peer)`. Cursor heads are stored as ASL pointers that reference CAS
records (`fed/cursor` schema). A peer key should be a stable identifier for the
remote (for example a federation registry domain id rendered as a decimal
string).
Push cursors are separate from pull cursors and live under
`fed/push_cursor/<peer>/head` (space scoped).
To avoid cursor collisions across multiple mounts to the same peer, pass
`remote_space_id=<space_id>` on cursor-aware endpoints. When provided, cursor
heads use `fed/cursor/<peer>/<remote_space_id>/head` and
`fed/push_cursor/<peer>/<remote_space_id>/head`. When omitted, the legacy v1
cursor names remain in effect for backward compatibility.
Read the current cursor for a peer:
Run local cursor/handler semantics checks (no daemon required):
```sh
curl --unix-socket amduatd.sock \
'http://localhost/v1/fed/cursor?peer=domain-2' \
-H 'X-Amduat-Space: demo'
./tests/changes_consumer_410.sh
./tests/changes_consumer_handler.sh
```
Scoped to a specific remote space:
Run AI connectivity and generation smoke eval (no daemon required):
```sh
curl --unix-socket amduatd.sock \
'http://localhost/v1/fed/cursor?peer=domain-2&remote_space_id=beta' \
-H 'X-Amduat-Space: demo'
./tests/ai_eval.sh
./tests/ai_answer_eval.sh
```
Write a cursor update (CAS-safe; include `expected_ref` to enforce; omitting it
only succeeds when the cursor is absent):
Run a fast end-to-end smoke (startup + ingest + sync + retrieve + tombstone):
```sh
curl --unix-socket amduatd.sock -X POST \
'http://localhost/v1/fed/cursor?peer=domain-2' \
-H 'Content-Type: application/json' \
-H 'X-Amduat-Space: demo' \
-d '{"last_logseq":123,"last_record_hash":"<ref>","expected_ref":"<ref>"}'
```
Cursor values are intended to drive incremental log/index scanning when that
infrastructure is available; the cursor endpoints themselves do not require the
index backend.
### Federation pull plan
You can ask the daemon to compute a read-only plan of which remote records would
be pulled from a peer given the current cursor:
```sh
curl --unix-socket amduatd.sock \
'http://localhost/v1/fed/pull/plan?peer=2&limit=128' \
-H 'X-Amduat-Space: demo'
```
The plan does not write artifacts, records, or cursors. It is deterministic and
returns only identifiers (logseq/ref), plus the next cursor candidate if the
plan were applied successfully.
Append `&remote_space_id=<space_id>` to use mount-specific cursor keying.
Apply a bounded batch of remote records (advances the cursor only after
success):
```sh
curl --unix-socket amduatd.sock -X POST \
'http://localhost/v1/fed/pull?peer=2&limit=128' \
-H 'X-Amduat-Space: demo'
```
`/v1/fed/pull` requires the index backend and will not advance the cursor on
partial failure.
Use `remote_space_id=<space_id>` to scope the cursor to a mount.
### Federation push plan (sender dry run)
Compute a read-only plan of what would be sent to a peer from the local log
since the push cursor (does not advance the cursor):
```sh
curl --unix-socket amduatd.sock \
'http://localhost/v1/fed/push/plan?peer=2&limit=128' \
-H 'X-Amduat-Space: demo'
```
`/v1/fed/push/plan` requires the index backend and uses a push cursor separate
from the pull cursor.
Append `&remote_space_id=<space_id>` to use mount-specific cursor keying.
### Federation push (sender apply)
Send local records to a peer (advances the push cursor only after all records
apply successfully on the peer):
```sh
curl --unix-socket amduatd.sock -X POST \
'http://localhost/v1/fed/push?peer=2&limit=128' \
-H 'X-Amduat-Space: demo'
```
`/v1/fed/push` uses `/v1/fed/ingest` on the peer and only advances the push
cursor after the batch completes. It requires the index backend.
Use `remote_space_id=<space_id>` to scope the cursor to a mount.
### Federation sync until caught up
Use the bounded helpers to repeatedly apply pull/push until no work remains,
with a hard `max_rounds` cap to keep requests bounded:
```sh
curl --unix-socket amduatd.sock -X POST \
'http://localhost/v1/fed/pull/until?peer=2&limit=128&max_rounds=10' \
-H 'X-Amduat-Space: demo'
```
```sh
curl --unix-socket amduatd.sock -X POST \
'http://localhost/v1/fed/push/until?peer=2&limit=128&max_rounds=10' \
-H 'X-Amduat-Space: demo'
```
### Federation ingest (receiver)
`/v1/fed/ingest` applies a single incoming record (push receiver). The request
is space-scoped via `X-Amduat-Space` and requires federation to be enabled;
otherwise the daemon responds with 503.
For artifact, per, and tgk_edge records, send raw bytes and provide metadata via
query params:
```sh
curl --unix-socket amduatd.sock -X POST \
'http://localhost/v1/fed/ingest?record_type=artifact&ref=<ref>' \
-H 'Content-Type: application/octet-stream' \
-H 'X-Amduat-Space: demo' \
--data-binary 'payload'
```
For tombstones, send a small JSON payload:
```sh
curl --unix-socket amduatd.sock -X POST \
'http://localhost/v1/fed/ingest' \
-H 'Content-Type: application/json' \
-H 'X-Amduat-Space: demo' \
-d '{"record_type":"tombstone","ref":"<ref>"}'
```
Notes:
- Record types: `artifact`, `per`, `tgk_edge`, `tombstone`.
- Size limit: 8 MiB per request.
- Tombstones use deterministic defaults: `scope=0`, `reason_code=0`.
Run the daemon with derivation indexing enabled:
```sh
./build/amduatd --root .amduat-asl --sock amduatd.sock --enable-derivation-index
```
## Space roots (GC)
`/v1/space/roots` enumerates the pointer heads that must be treated as GC roots
for the effective space, including federation cursor heads.
GC root sets MUST include federation cursors to avoid trimming artifacts still
reachable via replication state. Use the roots listing to build your root set
before running GC tooling.
Example:
```sh
curl --unix-socket amduatd.sock \
'http://localhost/v1/space/roots' \
-H 'X-Amduat-Space: demo'
```
## Space sync status
`/v1/space/sync/status` is a read-only summary of federation readiness and
per-peer cursor positions for the effective space. Peers are discovered from
cursor head pointers (pull and push) and returned in deterministic order.
```sh
curl --unix-socket amduatd.sock \
'http://localhost/v1/space/sync/status' \
-H 'X-Amduat-Space: demo'
```
The response groups cursor status per peer and per remote space id:
`peers:[{peer_key, remotes:[{remote_space_id, pull_cursor, push_cursor}]}]`.
`remote_space_id` is `null` for legacy v1 cursor heads.
## Space manifest
`/v1/space/manifest` returns the space manifest rooted at the deterministic
pointer head (`manifest/head` or `space/<space_id>/manifest/head`). The manifest
is stored in CAS as a record and returned with its ref plus a decoded,
deterministic JSON payload. If no manifest head is present, the endpoint
returns a 404.
```sh
curl --unix-socket amduatd.sock \
'http://localhost/v1/space/manifest' \
-H 'X-Amduat-Space: demo'
```
Create the manifest (only if no head exists yet):
```sh
curl --unix-socket amduatd.sock \
-X PUT 'http://localhost/v1/space/manifest' \
-H 'Content-Type: application/json' \
-H 'X-Amduat-Space: demo' \
--data-binary '{"version":1,"mounts":[]}'
```
Update with optimistic concurrency:
```sh
curl --unix-socket amduatd.sock \
-X PUT 'http://localhost/v1/space/manifest' \
-H 'Content-Type: application/json' \
-H 'X-Amduat-Space: demo' \
-H 'If-Match: <manifest_ref>' \
--data-binary @manifest.json
```
`If-Match` can be replaced with `?expected_ref=<manifest_ref>` if needed.
## Space mount resolution
`/v1/space/mounts/resolve` returns a deterministic, local-only view of the
space manifest mounts with their local pull cursor state. It performs no
network I/O and does not mutate storage. Track mounts indicate intent; syncing
remains a separate concern.
If no manifest head is present, the endpoint returns a 404.
Track mounts report `local_tracking.cursor_namespace` (`v2` when using
`remote_space_id`-keyed cursors).
```sh
curl --unix-socket amduatd.sock \
'http://localhost/v1/space/mounts/resolve' \
-H 'X-Amduat-Space: demo'
```
## Space workspace snapshot
`/v1/space/workspace` returns a deterministic, read-only snapshot for the
effective space. It aggregates the manifest, mount resolution, per-mount cursor
status, store backend metadata, federation flags, and store capabilities
(`capabilities.supported_ops`) into one JSON response. It performs no network
I/O and does not mutate storage.
This is a local snapshot that complements:
- `/v1/space/manifest` (manifest root + canonical manifest)
- `/v1/space/mounts/resolve` (resolved mounts + local tracking)
- `/v1/space/sync/status` (peer-wide cursor status)
- `/v1/space/mounts/sync/until` (active sync for track mounts)
```sh
curl --unix-socket amduatd.sock \
'http://localhost/v1/space/workspace' \
-H 'X-Amduat-Space: demo'
```
## Workspace UI
`/workspace` serves a minimal, human-facing page that consumes
`/v1/space/workspace` and `/v1/space/mounts/sync/until`, plus read-only
health panels for `/v1/space/doctor`, `/v1/space/roots`,
`/v1/space/sync/status`, `/v1/space/mounts/resolve`, and
`/v1/space/manifest`. It is a convenience view for inspection and manual sync
control, not a stable API. For programmatic use, call the `/v1/*` endpoints
directly.
## Space mounts sync (track mounts)
`/v1/space/mounts/sync/until` runs the federation pull/until loop for every
`track` mount in the current manifest using v2 cursor keying
(`remote_space_id = mount.space_id`). It is bounded by `limit`, `max_rounds`,
and `max_mounts`, returns per-mount status, and continues after errors.
Requires federation enabled and the index backend. If no manifest head is
present, the endpoint returns a 404.
```sh
curl --unix-socket amduatd.sock -X POST \
'http://localhost/v1/space/mounts/sync/until?limit=128&max_rounds=10&max_mounts=32' \
-H 'X-Amduat-Space: demo'
```
To fail `/v1/pel/run` if the derivation index write fails:
```sh
./build/amduatd --root .amduat-asl --sock amduatd.sock --derivation-index-strict
```
Dev loop (build + restart):
```sh
./scripts/dev-restart.sh
```
## Federation smoke test
Run the end-to-end federation smoke test (starts two local daemons, verifies
pull replication A→B and push replication B→A, and checks cursors):
```sh
./scripts/test_fed_smoke.sh
```
The test requires the index backend and either `curl` with `--unix-socket`
support or the built-in `build/amduatd_http_unix` helper.
Query store meta:
```sh
curl --unix-socket amduatd.sock http://localhost/v1/meta
```
Browser UI (use `socat` to forward the Unix socket):
```sh
socat TCP-LISTEN:8080,fork,reuseaddr UNIX-CONNECT:amduatd.sock
```
Then open `http://localhost:8080/v1/ui` (concept editor).
Discover the store-backed API contract ref:
```sh
curl --unix-socket amduatd.sock 'http://localhost/v1/contract?format=ref'
```
Fetch the contract bytes (JSON):
```sh
curl --unix-socket amduatd.sock http://localhost/v1/contract
```
Upload raw bytes:
```sh
curl --unix-socket amduatd.sock -X POST http://localhost/v1/artifacts \
-H 'Content-Type: application/octet-stream' \
--data-binary 'hello'
```
Download raw bytes:
```sh
curl --unix-socket amduatd.sock http://localhost/v1/artifacts/<ref>
```
Download artifact framing (`ENC/ASL1-CORE v1`):
```sh
curl --unix-socket amduatd.sock \
'http://localhost/v1/artifacts/<ref>?format=artifact' --output artifact.bin
```
Run a PEL program from store-backed refs (default `scheme_ref=dag`):
```sh
curl --unix-socket amduatd.sock -X POST http://localhost/v1/pel/run \
-H 'Content-Type: application/json' \
-d '{"program_ref":"<program_ref>","input_refs":["<input_ref_0>"],"params_ref":"<params_ref>"}'
```
Run a v2 PEL execute request with inline artifact ingest:
```sh
curl --unix-socket amduatd.sock -X POST http://localhost/v2/pel/execute \
-H 'Content-Type: application/json' \
-d '{
"scheme_ref":"dag",
"program_ref":"<program_ref>",
"inputs":{
"refs":["<input_ref_0>"],
"inline_artifacts":[{"body_hex":"48656c6c6f2c20763221","type_tag":"0x00000000"}]
},
"receipt":{
"input_manifest_ref":"<manifest_ref>",
"environment_ref":"<env_ref>",
"evaluator_id":"local-amduatd",
"executor_ref":"<executor_ref>",
"started_at":1731000000,
"completed_at":1731000001
}
}'
```
The v2 execute response returns `run_ref` (and `result_ref` alias),
`receipt_ref`, `stored_input_refs[]`, `output_refs[]`, and `status`.
Simplified async v2 operations (PEL-backed under the hood):
```sh
# put (returns job_id)
curl --unix-socket amduatd.sock -X POST http://localhost/v2/ops/put \
-H 'Content-Type: application/json' \
-d '{"body_hex":"48656c6c6f","type_tag":"0x00000000"}'
# concat (returns job_id)
curl --unix-socket amduatd.sock -X POST http://localhost/v2/ops/concat \
-H 'Content-Type: application/json' \
-d '{"left_ref":"<ref_a>","right_ref":"<ref_b>"}'
# slice (returns job_id)
curl --unix-socket amduatd.sock -X POST http://localhost/v2/ops/slice \
-H 'Content-Type: application/json' \
-d '{"ref":"<ref>","offset":1,"length":3}'
# poll job
curl --unix-socket amduatd.sock http://localhost/v2/jobs/1
# get bytes
curl --unix-socket amduatd.sock http://localhost/v2/get/<ref>
```
When derivation indexing is enabled, successful PEL runs record derivations under
`<root>/index/derivations/by_artifact/` keyed by output refs (plus result/trace/receipt refs).
Define a PEL/PROGRAM-DAG/1 program (store-backed):
```sh
curl --unix-socket amduatd.sock -X POST http://localhost/v1/pel/programs \
-H 'Content-Type: application/json' \
-d '{"nodes":[{"id":1,"op":{"name":"pel.bytes.concat","version":1},"inputs":[{"external":{"input_index":0}},{"external":{"input_index":1}}],"params_hex":""}],"roots":[{"node_id":1,"output_index":0}]}'
```
Create a named concept and publish a ref (so you can use the name instead of hex refs):
```sh
curl --unix-socket amduatd.sock -X POST http://localhost/v1/concepts \
-H 'Content-Type: application/json' \
-d '{"name":"hello","ref":"<program_ref>"}'
```
Publish a new version:
```sh
curl --unix-socket amduatd.sock -X POST http://localhost/v1/concepts/hello/publish \
-H 'Content-Type: application/json' \
-d '{"ref":"<program_ref_v2>"}'
```
Resolve the latest ref:
```sh
curl --unix-socket amduatd.sock http://localhost/v1/resolve/hello
```
Inspect concepts:
```sh
curl --unix-socket amduatd.sock http://localhost/v1/concepts
curl --unix-socket amduatd.sock http://localhost/v1/concepts/hello
```
Artifact info (length + type tag):
```sh
curl --unix-socket amduatd.sock 'http://localhost/v1/artifacts/<ref>?format=info'
```
## Space selection
Requests can select a space via the `X-Amduat-Space` header:
```sh
curl --unix-socket amduatd.sock http://localhost/v1/concepts \
-H 'X-Amduat-Space: demo'
```
Precedence rules:
- `X-Amduat-Space` header (if present)
- daemon `--space` default (if configured)
- unscoped names (no space)
When capability tokens are used, the requested space must match the token's
space (or the token must be unscoped), otherwise the request is rejected.
## Space doctor
Check deterministic invariants for the effective space:
```sh
curl --unix-socket amduatd.sock http://localhost/v1/space/doctor
curl --unix-socket amduatd.sock http://localhost/v1/space/doctor \
-H 'X-Amduat-Space: demo'
```
When the daemon uses the `fs` store backend, index-only checks are reported as
`"skipped"`; the `index` backend runs them.

- `GET /v2/graph/nodes/{name}/neighbors?dir=&predicate=&limit=&cursor=&as_of=&provenance_ref=&include_tombstoned=&expand_names=&expand_artifacts=` → neighbor scan (paged, snapshot-bounded; tombstoned edges excluded by default unless `include_tombstoned=true`; optional provenance filter; add names/latest refs via expansion flags)
- `GET /v2/graph/search?name_prefix=&limit=&cursor=&as_of=` → search nodes by name prefix (paged, snapshot-bounded)
- `GET /v2/graph/paths?from=&to=&max_depth=&predicate=&as_of=&k=&expand_names=&expand_artifacts=&include_tombstoned=&provenance_ref=&max_fanout=&max_result_bytes=&include_stats=` → shortest directed path query (bounded BFS, snapshot-bounded, returns up to `k` paths with hop metadata and optional names/latest refs; tombstoned edges excluded by default unless `include_tombstoned=true`; optional provenance filter; supports fanout/response-size guards and optional stats)
- `GET /v2/graph/subgraph?roots[]=&max_depth=&max_fanout=&predicates[]=&dir=&as_of=&include_versions=&include_tombstoned=&limit_nodes=&limit_edges=&cursor=&provenance_ref=&max_result_bytes=&include_stats=` → bounded multi-hop subgraph retrieval from roots (snapshot-bounded, paged by opaque `next_cursor`; tombstoned edges excluded by default unless `include_tombstoned=true`; optional provenance filter; supports fanout/response-size guards and optional stats; returns `{nodes[], edges[], frontier?[], next_cursor, truncated}`)
- `POST /v2/graph/edges` → append graph edge `{subject, predicate, object, metadata_ref?|provenance?}` (`metadata_ref` and `provenance` are mutually exclusive)
- `POST /v2/graph/edges/tombstone` → append tombstone for an existing edge `{edge_ref, metadata_ref?|provenance?}` (append-only correction/retraction; `metadata_ref` and `provenance` are mutually exclusive)
- `POST /v2/graph/batch` → apply mixed graph mutations `{idempotency_key?, mode?, nodes?, versions?, edges?}` (versions/edges items support `metadata_ref?|provenance?`; mode: `fail_fast|continue_on_error`; deterministic replay for repeated `idempotency_key` + identical payload; returns `{ok, applied, results[]}` with per-item status/error)
- `POST /v2/graph/query` → unified graph query `{where?, predicates?, direction?, include_versions?, include_tombstoned?, include_stats?, max_result_bytes?, as_of?, limit?, cursor?}` returning `{nodes[], edges[], paging, stats?}` (`nodes[].versions[]` included when `include_versions=true`; `where.provenance_ref` filters edges linked via `ms.has_provenance`; tombstoned edges are excluded as-of snapshot unless `include_tombstoned=true`)
- `POST /v2/graph/retrieve` → agent-oriented bounded retrieval `{roots[], goal_predicates?[], max_depth?, as_of?, provenance_min_confidence?, include_versions?, include_tombstoned?, max_fanout?, limit_nodes?, limit_edges?, max_result_bytes?}` returning `{nodes[], edges[], explanations[], truncated, stats}` (multi-hop traversal from roots with optional predicate targeting and provenance-confidence gating; each explanation includes edge inclusion reasons and traversal depth)
- `POST /v2/graph/export` → paged graph envelope export `{as_of?, cursor?, limit?, predicates?[], roots?[], include_tombstoned?, max_result_bytes?}` returning `{items[], next_cursor, has_more, snapshot_as_of, stats}` (`items[]` preserve edge refs/order plus predicate, tombstone flag, and attached `metadata_ref` when present)
- `POST /v2/graph/import` → ordered graph envelope replay `{mode?, items[]}` (`mode=fail_fast|continue_on_error`) returning `{ok, applied, results[]}` with per-item `index/status/code/error/edge_ref`
- `GET /v2/graph/schema/predicates` → current graph governance policy `{mode, provenance_mode, predicates[]}` where `mode` is `strict|warn|off` and `provenance_mode` is `optional|required`
- `POST /v2/graph/schema/predicates` → update graph governance `{mode?, provenance_mode?, predicates?[]}` (`predicates[]` entries accept `{predicate_ref|predicate, domain?, range?}`; predicate validation mode is enforced for edge writes in `POST /v2/graph/edges`, batch edge items, and graph import edge items; `provenance_mode=required` enforces provenance attachment (`metadata_ref` or `provenance`) for version/edge/tombstone writes; policy is persisted per space root)
- `GET /v2/graph/stats` → graph/index health summary `{edges_total, aliases_total, index{...}, tombstones{edges, ratio}}`
- `GET /v2/graph/capabilities` → graph feature/version negotiation payload `{contract, graph{version, features, limits, modes}, runtime{...}}`
- `GET /v2/graph/changes?since_cursor=&since_as_of=&limit=&wait_ms=&event_types[]=&predicates[]=&roots[]=` → incremental appended graph events with strict cursor replay window (returns `410` when cursor falls outside retained window), resumable cursor tokens, optional long-poll (`wait_ms`), and event/predicate/root filters; response `{events[], next_cursor, has_more}`
- `GET /v2/graph/edges?subject=&predicate=&object=&dir=&limit=&cursor=&as_of=&expand_names=&expand_artifacts=&provenance_ref=&include_tombstoned=&max_result_bytes=&include_stats=` → filtered edge scan with paging (`dir=any|outgoing|incoming`, snapshot-bounded; tombstoned edges excluded by default unless `include_tombstoned=true`; optional provenance filter; add names/latest refs via expansion flags; supports response-size guards and optional stats)
- graph paging cursors are opaque tokens (`g1_*`); legacy numeric cursors are still accepted
- `GET /v2/graph/nodes/{name}?as_of=&include_tombstoned=` → `{name, concept_ref, latest_ref, versions[], outgoing[], incoming[]}` (`latest_ref` is resolved from visible versions at `as_of`; tombstoned versions excluded by default)
- `GET /v2/graph/history/{name}?as_of=&include_tombstoned=` → event timeline for node versions/edges (snapshot-bounded; `latest_ref` and tombstoned fact events both respect same visibility rules)
Graph client helper examples for agent flows are in `scripts/graph_client_helpers.sh`:
- `batch-ingest` (idempotent batch write helper)
- `sync-once` (incremental changes cursor step)
- `subgraph` (bounded retrieval helper)
- `POST /v1/pel/programs`
- request: authoring JSON for `PEL/PROGRAM-DAG/1` (kernel ops only; `params_hex` is raw hex bytes)
- response: `{program_ref}`
- `POST /v1/context_frames`
UI (human-facing, not an API contract):
- `GET /workspace` → minimal workspace snapshot + sync controls (uses `/v1/space/workspace`)
Receipt example (with v1.1 fields):
```json

## Notes
- This is intentionally a local-first surface (Unix socket, no TLS). HTTPS can be added later without changing the semantics.
- This scaffold assumes local Unix-socket access to `amduatd`.
- Graph cursors are opaque and must be persisted exactly as returned.
- `./scripts/sync_loop.sh` and `sync-loop` CLI are deprecated compatibility aliases.
- Keep `contracts/amduatd-api-contract.v2.json` in sync with upstream when you pull updates.

# AI v2 Plan
## Goal
Ship one reliable AI vertical slice on top of the v2 graph API:
1. ingest deterministic graph facts,
2. retrieve graph context for a root,
3. answer with grounding evidence,
4. execute a minimal planner loop with persisted run state.
## Scope Rules
- Prioritize app-level AI workflow work in this repo.
- Treat backend fault investigation as out-of-scope unless it blocks the vertical slice.
- Keep `vendor/amduat-api` pinned while iterating on prompts/evals.
## Working Lane
- Use branch: `feat/ai-v2-experiments`.
- Keep core command stable: `./scripts/v2_app.sh ai-vertical-slice`.
- Track prompt/eval tweaks under `ai/`.
## Acceptance Criteria
- `./scripts/v2_app.sh ai-vertical-slice` passes on a running daemon with Ollama.
- Output contains non-empty answer text with `grounding.has_evidence == true`.
- `tests/ai_eval.sh` and `tests/ai_answer_eval.sh` pass in the same environment.
- `./scripts/v2_app.sh ai-agent --json 'doc-ai-1' 'What domain is doc-ai-1 in?' 'ms.within_domain'` writes checkpoint state under `ai/runs/`.
## Quick Run Sequence
1. Start daemon (or let the vertical slice auto-start it):
`./scripts/dev_start_daemon.sh`
2. Run AI vertical slice:
`./scripts/v2_app.sh ai-vertical-slice`
3. If daemon may not be running, use:
`./scripts/v2_app.sh ai-vertical-slice --auto-start-daemon`
4. Run minimal agent loop:
`./scripts/v2_app.sh ai-agent --json --auto-start-daemon 'doc-ai-1' 'What domain is doc-ai-1 in?' 'ms.within_domain'`
## Stop Conditions
- If startup, ingest, or retrieve fails due to backend regression, log the failure and pause AI iteration until fixed.
- Do not switch scope to broad backend cleanup without an explicit decision.

# amduatd API v2 Design (PEL-only writes)
## Status
Draft proposal for discussion.
First server slice implemented: `POST /v2/pel/execute` with `inputs.refs`,
`inputs.inline_artifacts[{body_hex,type_tag?}]`, and required `receipt`.
## Goals
- Keep `amduatd` thin: transport, parsing, auth, and mapping to core calls.
- Make **PEL the only write primitive** in HTTP v2.
- Enforce artifact provenance for writes: adding new artifacts must go through:
1. store inputs,
2. run a PEL program,
3. persist and return receipt.
- Keep `/v1/*` behavior unchanged while v2 is introduced.
## Non-goals
- Re-implementing PEL semantics in `amduat-api`.
- Creating new substrate semantics in daemon code.
- Removing v1 immediately.
## High-level model
v2 separates read and write concerns:
- Read paths remain direct and deterministic (`GET /v2/meta`, `GET /v2/artifacts/{ref}`, federation/space read endpoints).
- All state-changing operations are executed as PEL runs.
In v2, `POST /v1/artifacts` equivalent is replaced by a mutation endpoint that always drives a PEL run.
For simplified clients, v2 also exposes async operation endpoints:
- `POST /v2/ops/put`
- `POST /v2/ops/concat`
- `POST /v2/ops/slice`
- `GET /v2/jobs/{id}`
These enqueue work and execute PEL in the daemon background loop.
Graph-oriented endpoints can be added as thin wrappers over concepts/relations:
- `POST /v2/graph/nodes` (maps to concept create/publish)
- `POST /v2/graph/edges` (maps to relation edge append)
- `GET /v2/graph/nodes/{name}` (node + versions + incoming/outgoing edges)
- `GET /v2/graph/history/{name}` (version + edge timeline)
## Versioning and contract id
- Base path: `/v2`
- Contract id: `AMDUATD/API/2`
- Keep the same store-seeded contract model used in v1.
## Endpoint shape
### Read-only endpoints (v2)
- `GET /v2/meta`
- `GET /v2/contract`
- `GET /v2/artifacts/{ref}`
- `HEAD /v2/artifacts/{ref}`
- `GET /v2/artifacts/{ref}?format=info`
- Space/federation read endpoints can be mirrored under `/v2/*` unchanged where possible.
### Write endpoints (v2)
- `POST /v2/pel/execute`
No direct artifact write endpoint in v2 (`POST /v2/artifacts` is intentionally absent).
## `POST /v2/pel/execute`
Single mutation primitive for v2.
### Request
```json
{
"program_ref": "<hex-ref-or-name>",
"scheme_ref": "dag",
"params_ref": "<optional-ref-or-name>",
"inputs": {
"refs": ["<hex-ref-or-name>"],
"inline_artifacts": [
{
"content_type": "application/octet-stream",
"type_tag": "0x00000000",
"body_hex": "48656c6c6f"
}
]
},
"receipt": {
"input_manifest_ref": "<ref-or-name>",
"environment_ref": "<ref-or-name>",
"evaluator_id": "local-amduatd",
"executor_ref": "<ref-or-name>",
"started_at": 1731000000,
"completed_at": 1731000005
},
"effects": {
"publish_outputs": true,
"append_fed_log": true
}
}
```
### Processing contract
Server behavior is deterministic and ordered:
1. Resolve `program_ref`, `scheme_ref`, `params_ref`, and `inputs.refs` to refs.
2. Decode and store `inputs.inline_artifacts` into ASL store.
3. Build effective `input_refs = refs + stored_inline_refs`.
4. Execute PEL using core `pel_surf_run_with_result`.
5. Build FER receipt from run result + receipt fields.
6. Store receipt artifact and return `receipt_ref`.
7. Apply requested side effects (`publish_outputs`, `append_fed_log`) after successful run.
If any step fails:
- return non-2xx,
- do not publish outputs,
- do not append federation publish records.
## Response
```json
{
"run_ref": "<pel1-result-ref>",
"trace_ref": "<optional-trace-ref>",
"receipt_ref": "<fer1-receipt-ref>",
"stored_input_refs": ["<ref>"],
"output_refs": ["<ref>"],
"status": "OK"
}
```
Notes:
- `stored_input_refs` are refs created from `inline_artifacts`.
- `receipt_ref` is required for successful writes in v2.
## Error model
- `400` invalid request or schema violation.
- `404` referenced input/program/params not found.
- `409` conflict in post-run side effects (e.g. cursor/update conflicts).
- `422` run completed but business policy failed (reserved for policy checks).
- `500` internal failure.
Error payload:
```json
{
"error": {
"code": "invalid_input_ref",
"message": "input ref not found",
"retryable": false
}
}
```
## Behavioral differences from v1
- Removed write path: direct `POST /artifacts`.
- New requirement: every write returns a receipt ref tied to a PEL run.
- `pel/run` semantics become the write gateway rather than an optional compute endpoint.
## Compatibility and rollout
1. Add `/v2/pel/execute` while keeping `/v1/*` unchanged.
2. Mirror core read endpoints under `/v2/*`.
3. Mark `POST /v1/artifacts` as deprecated in docs.
4. Migrate clients to v2 execute flow.
5. Remove v1 write endpoints in a later major release.
## Open questions
- Should v2 require exactly one output for write operations, or allow multiple outputs with one receipt?
- Should inline artifact body support both `body_hex` and `body_base64`, or move to multipart for large payloads?
- Should `publish_outputs` default to `true` or be explicit-only?
- Do we need async execution (`202 + run status endpoint`) for long-running programs in v2?
## Minimal implementation plan
1. Add v2 contract bytes (`registry/amduatd-api-contract.v2.json`).
2. Add `/v2/pel/execute` handler by adapting existing `POST /v1/pel/run` + artifact ingest path.
3. Factor shared receipt parsing/building from current v1 pel handler.
4. Add tests:
- inline artifact -> stored -> run -> receipt success,
- failure before run,
- failure during run,
- side effect gating (no publish on failure).
5. Document deprecation notice for `POST /v1/artifacts`.

Absolutely — here’s a **draft for ENC-ASL-TGK-INDEX**, carefully merging ASL artifact indexes and TGK edge indexes while respecting the **separation of concerns** and **snapshot determinism**.
This design keeps **ENC-ASL-CORE** and **ENC-TGK-CORE** authoritative, and only merges **index references and acceleration structures**.
---
# ENC-ASL-TGK-INDEX
### Merged On-Disk Index for ASL Artifacts and TGK Edges
---
## 1. Purpose
ENC-ASL-TGK-INDEX defines a **unified on-disk index** that:
* References **ASL artifacts** (ENC-ASL-CORE)
* References **TGK edges** (ENC-TGK-CORE)
* Supports **routing keys, filters, sharding, SIMD acceleration** per ASL-INDEX-ACCEL
* Preserves **snapshot safety, log-sequence ordering, and immutability**
> Semantic data lives in the respective CORE layers; this index layer **only stores references**.
---
## 2. Layering Principle
| Layer | Responsibility |
| --------------------- | -------------------------------------------- |
| ENC-ASL-CORE | Artifact structure and type tags |
| ENC-TGK-CORE | Edge structure (`from[] → to[]`) |
| TGK-INDEX / ASL-INDEX | Canonical & routing keys, index semantics |
| ENC-ASL-TGK-INDEX | On-disk references and acceleration metadata |
**Invariant:** This index never re-encodes artifacts or edges.
---
## 3. Segment Layout
Segments are **append-only** and **snapshot-bound**:
```
+-----------------------------+
| Segment Header |
+-----------------------------+
| Routing Filters |
+-----------------------------+
| ASL Artifact Index Records |
+-----------------------------+
| TGK Edge Index Records |
+-----------------------------+
| Optional Acceleration Data |
+-----------------------------+
| Segment Footer |
+-----------------------------+
```
* Segment atomicity enforced
* Footer checksum guarantees integrity
---
## 4. Segment Header
```c
struct asl_tgk_index_segment_header {
uint32_t magic; // 'ATXI'
uint16_t version;
uint16_t flags;
uint64_t segment_id;
uint64_t logseq_min;
uint64_t logseq_max;
uint64_t asl_record_count;
uint64_t tgk_record_count;
uint64_t record_area_offset;
uint64_t footer_offset;
};
```
* `logseq_*` enforce snapshot visibility
* Separate counts for ASL and TGK entries
---
## 5. Routing Filters
Filters may be **segmented by type**:
* **ASL filters**: artifact hash + type tag
* **TGK filters**: canonical edge ID + edge type key + optional role
```c
struct asl_tgk_filter_header {
uint16_t filter_type; // e.g., BLOOM, XOR
uint16_t version;
uint32_t flags;
uint64_t size_bytes; // length of filter payload
};
```
* Filters are advisory; false positives allowed, false negatives forbidden
* Must be deterministic per snapshot
---
## 6. ASL Artifact Index Record
```c
struct asl_index_record {
uint64_t logseq;
uint64_t artifact_id; // ENC-ASL-CORE reference
uint32_t type_tag; // optional
uint8_t has_type_tag; // 0 or 1
uint16_t flags; // tombstone, reserved
};
```
* `artifact_id` = canonical identity
* No artifact payload here
---
## 7. TGK Edge Index Record
```c
struct tgk_index_record {
uint64_t logseq;
uint64_t tgk_edge_id; // ENC-TGK-CORE reference
uint32_t edge_type_key; // optional
uint8_t has_edge_type;
uint8_t role; // optional from/to/both
uint16_t flags; // tombstone, reserved
};
```
* `tgk_edge_id` = canonical TGK-CORE edge ID
* No node lists stored in index
---
## 8. Optional Node-Projection Records
For acceleration:
```c
struct node_edge_ref {
uint64_t logseq;
uint64_t node_id; // from/to node
uint64_t tgk_edge_id;
uint8_t position; // from or to
};
```
* Fully derivable from TGK-CORE edges
* Optional; purely for lookup speed
---
## 9. Sharding and SIMD
* Shard assignment is **routing key based** (ASL artifact or TGK edge)
* SIMD arrays may store precomputed routing keys for fast filter evaluation
* Must follow ASL-INDEX-ACCEL invariants: deterministic, immutable, snapshot-safe
---
## 10. Snapshot Interaction
At snapshot `S`:
* Segment visible if `logseq_min ≤ S`
* ASL or TGK record visible if `logseq ≤ S`
* Tombstones shadow earlier records
* Filters may be used as advisory before canonical verification
---
## 11. Segment Footer
```c
struct asl_tgk_index_segment_footer {
uint64_t checksum; // covers header, filters, records
uint64_t asl_record_bytes;
uint64_t tgk_record_bytes;
uint64_t filter_bytes;
};
```
* Ensures atomicity and completeness
---
## 12. Normative Invariants
1. **ASL artifact identity = ENC-ASL-CORE artifact ID**
2. **TGK edge identity = ENC-TGK-CORE edge ID**
3. Edge type tag and artifact type tag **do not affect canonical identity**
4. Filters are advisory only; no false negatives
5. Sharding is observationally invisible
6. Index records are immutable once written
7. Snapshot visibility strictly follows `logseq`
8. Determinism guaranteed per snapshot
---
## 13. Summary
ENC-ASL-TGK-INDEX merges ASL artifacts and TGK edges into a **single, snapshot-safe, acceleration-friendly index layer**:
* Keeps core semantics authoritative
* Enables high-performance lookups using routing, sharding, SIMD, and filters
* Preserves immutability and determinism
* Fully compatible with ASL-INDEX-ACCEL principles
This design supports billions of references while avoiding semantic collisions between ASL and TGK layers.
---
If you want, the next step could be **drafting a unified query execution model** over this merged index, connecting **artifact lookups** and **TGK graph traversals** in a snapshot-safe, deterministic way.
Do you want me to do that next?

# Federation Coordinator Middle Layer Spec
This document specifies the middle-layer coordinator that orchestrates federation
above the core C substrate. It remains transport- and policy-aware while keeping
core semantics unchanged.
## Scope and Goals
- Maintain per-domain replay bounds and an admitted set.
- Fetch and ingest published records from remotes.
- Build federation views via core APIs.
- Resolve missing bytes by fetching artifacts into a cache store.
- Keep storage layout private (no extents or blocks exposed).
- Align with tier1 federation semantics and replay determinism.
- Federation view is the union of admitted domains regardless of topology.
Non-goals:
- Re-implement core semantics in this layer.
- Introduce a single global snapshot ID (federation is per-domain).
## Core Dependencies
The coordinator calls into vendor core APIs (`vendor/amduat/include/amduat/fed/*`)
and MUST stay aligned with their signatures:
- `amduat_fed_registry_*` (persist per-domain admission state)
- `amduat_fed_ingest_validate` (record validation + conflict detection)
- `amduat_fed_replay_build` (deterministic replay per domain)
- `amduat_fed_view_build` + `amduat_fed_resolve` (build view and resolve ref-only)
Core expects per-domain replay bounds `{domain_id, snapshot_id, log_prefix}` and
does not handle transport, auth, caching policy, or remote fetch.
Alignment note: the daemon-layer API in this repo still needs updates to match
current vendor core types and signatures. This spec reflects vendor headers as
the source of truth.
Tier1 alignment (normative):
- `ASL/FEDERATION/1`
- `ASL/FEDERATION-REPLAY/1`
- `ASL/DOMAIN-MODEL/1`
- `ASL/POLICY-HASH/1`
- `ENC/ASL-CORE-INDEX/1` (canonical in `vendor/amduat/tier1/enc-asl-core-index-1.md`)
## Data Structures
### Registry State (per domain, persisted)
```
struct amduat_fed_domain_state {
uint32_t domain_id;
uint64_t snapshot_id;
uint64_t log_prefix;
uint64_t last_logseq;
uint8_t admitted;
uint8_t policy_ok;
uint8_t reserved[6];
amduat_hash_id_t policy_hash_id;
amduat_octets_t policy_hash; /* Empty when unknown; caller-owned bytes. */
};
```
Registry bytes are stored via `amduat_fed_registry_store_*` in the local ASL
store; the coordinator owns admission workflows and policy compatibility checks.
### Admitted Set (in-memory)
```
struct amduat_fed_admitted_set {
uint32_t *domain_ids; // sorted, unique
size_t len;
};
```
The admitted set is derived from registry entries with `admitted != 0` and
`policy_ok != 0`.
### Snapshot Vector (per view build)
```
struct amduat_fed_snapshot_vector {
amduat_fed_view_bounds_t *bounds;
size_t len;
uint64_t vector_epoch;
};
```
### Record Staging (per fetch batch)
```
struct amduat_fed_record {
amduat_fed_record_meta_t meta;
amduat_fed_record_id_t id;
uint64_t logseq;
uint64_t snapshot_id;
uint64_t log_prefix;
};
```
Records MUST carry the fields required by `ASL/FEDERATION-REPLAY/1`, and replay
ordering MUST be deterministic (sort by `logseq`, then canonical identity).
Record metadata includes visibility and optional cross-domain source identity.
### View and Policy Denies
```
struct amduat_fed_view_bounds {
uint32_t domain_id;
uint64_t snapshot_id;
uint64_t log_prefix;
};
struct amduat_fed_policy_deny {
amduat_fed_record_id_t id;
uint32_t reason_code;
};
```
### Fetch Backlog / Retry State
```
struct amduat_fed_fetch_state {
uint32_t domain_id;
uint64_t next_snapshot_id;
uint64_t next_log_prefix;
uint64_t next_logseq;
uint64_t backoff_ms;
uint64_t last_attempt_ms;
uint32_t consecutive_failures;
};
```
### Cache Store Metadata (optional)
```
struct amduat_fed_cache_policy {
bool enabled;
uint64_t max_bytes;
uint64_t used_bytes;
uint32_t ttl_seconds;
uint32_t prefetch_depth;
};
```
## Coordinator Interfaces
### Configuration
```
struct amduat_fed_coord_cfg {
const char *registry_path;
amduat_asl_store_t *authoritative_store;
amduat_asl_store_t *cache_store; // optional
amduat_asl_store_t *session_store; // optional
amduat_fed_transport transport;
amduat_fed_cache_policy cache_policy;
amduat_fed_policy_hooks policy_hooks;
};
```
### Lifecycle and Operations
```
int amduat_fed_coord_open(
const struct amduat_fed_coord_cfg *cfg,
struct amduat_fed_coord **out);
int amduat_fed_coord_close(struct amduat_fed_coord *c);
int amduat_fed_coord_load_registry(struct amduat_fed_coord *c);
int amduat_fed_coord_set_admitted(
struct amduat_fed_coord *c,
uint32_t domain_id,
bool admitted);
int amduat_fed_coord_tick(struct amduat_fed_coord *c, uint64_t now_ms);
int amduat_fed_coord_resolve(
struct amduat_fed_coord *c,
amduat_reference_t ref,
amduat_artifact_t *out);
```
## API Status
Planned coordinator surface (not yet implemented):
- `amduat_fed_coord_open`
- `amduat_fed_coord_close`
- `amduat_fed_coord_load_registry`
- `amduat_fed_coord_set_admitted`
- `amduat_fed_coord_tick`
- `amduat_fed_coord_resolve`
Implemented in core (already available):
- `amduat_fed_registry_*`
- `amduat_fed_ingest_validate`
- `amduat_fed_replay_build`
- `amduat_fed_view_build`
- `amduat_fed_resolve`
## Transport Abstraction
Minimal interface that hides protocol, auth, and topology:
```
struct amduat_fed_transport {
int (*get_records)(
void *ctx, uint32_t domain_id,
uint64_t snapshot_id, uint64_t log_prefix,
uint64_t from_logseq,
amduat_fed_record_iter *out_iter);
int (*get_artifact)(
void *ctx, amduat_reference_t ref,
amduat_sink *out_sink);
};
```
Transport MUST return records that can be validated with `amduat_fed_record_validate`
and MUST provide all fields required by `ASL/FEDERATION-REPLAY/1`.
Transport MUST NOT surface internal-only records from foreign domains.
## Storage and Encodings
- The coordinator stores records/artifacts via ASL store APIs and does not touch
segment layouts or extents directly.
- Federation metadata in index records is encoded by core per
`ENC/ASL-CORE-INDEX/1`; the coordinator must not override it.
- Cache store semantics are best-effort and do not affect authoritative state.
## Policies
- Admission is per-domain and controlled via registry entries and `policy_ok`.
- Policy compatibility uses `policy_hash_id` + `policy_hash` (ASL/POLICY-HASH/1).
- `policy_ok` is computed during admission by comparing local policy hash to the
remote domain's published policy hash.
- Admission and policy compatibility MUST be enforced before any foreign state is
admitted into the federation view.
- Per-record filtering, if used, MUST be deterministic and SHOULD be expressed
as policy denies passed to `amduat_fed_view_build` rather than by dropping
records before validation.
- Cache write policy is middle-layer only (fetch-on-miss, optional prefetch).
- Eviction is local (LRU or segmented queues) and must not leak layout.
- Conflict policy: reject on identity collision with differing metadata and keep
bounds stable until operator intervention (ASL/FEDERATION-REPLAY/1).
## Sequencing and Consistency
- Deterministic views require a stable snapshot vector per build.
- Bounds advance only after successful ingest; they never move backwards.
- Before validation, records are ordered by `(logseq, canonical identity)` and
filtered to `logseq <= log_prefix`.
- Tombstones and shadowing apply only within the source domain.
- Use `vector_epoch` to swap snapshot vectors atomically after a build.
- Persist registry updates atomically via `amduat_fed_registry_store_put` before
swapping the snapshot vector.
- If a remote retracts or regresses, keep local bounds and mark domain degraded.
## Core Flow
### Startup
- Load registry.
- Derive admitted set from `admitted != 0` and `policy_ok != 0`.
- Build initial snapshot vector.
### Periodic Tick
- For each admitted domain, fetch records up to bound and validate.
- Update `last_logseq`, and advance bounds if remote snapshot moves forward.
- Build federation view using `amduat_fed_view_build` over the staged records,
with optional policy denies derived from coordinator hooks.
- Swap snapshot vector atomically after registry updates.
### Resolve Loop
- Call `amduat_fed_resolve` against the latest built `amduat_fed_view_t`.
- If `AMDUAT_FED_RESOLVE_FOUND_REMOTE_NO_BYTES`, fetch bytes via transport into cache store.
- Retry resolve after cache write completes.
## Example Tick Pseudocode
```
int amduat_fed_coord_tick(struct amduat_fed_coord *c, uint64_t now_ms) {
amduat_fed_snapshot_vector vec = build_snapshot_vector(c);
clear(staged_records_all);
build_policy_denies(&policy_denies, &policy_denies_len);
for each domain in vec.bounds:
bound = &vec.bounds[i];
if !admitted(bound->domain_id) continue;
if backoff_active(bound->domain_id, now_ms) continue;
clear(staged_records);
iter = transport.get_records(
bound->domain_id,
bound->snapshot_id,
bound->log_prefix,
state.next_logseq);
while iter.next(record):
if !amduat_fed_record_validate(&record):
mark_domain_error(bound->domain_id);
break;
append(staged_records, record);
sort_by_logseq_then_id(staged_records);
clamp_to_log_prefix(staged_records, bound->log_prefix);
rc = amduat_fed_ingest_validate(
staged_records, staged_len, &err_index, &conflict_index);
if rc == AMDUAT_FED_INGEST_ERR_CONFLICT:
mark_domain_error(bound->domain_id);
continue;
if rc == AMDUAT_FED_INGEST_ERR_INVALID:
mark_domain_error(bound->domain_id);
continue;
update_registry_bounds(bound->domain_id, state);
append_all(staged_records_all, staged_records);
amduat_fed_view_build(
staged_records_all, staged_len_all,
local_domain_id, vec.bounds, vec.len,
policy_denies, policy_denies_len,
&view);
swap_snapshot_vector(c, build_snapshot_vector(c));
return 0;
}
```
## Example Resolve Pseudocode
```
int amduat_fed_coord_resolve(
struct amduat_fed_coord *c,
amduat_reference_t ref,
amduat_artifact_t *out) {
view = c->last_view;
rc = amduat_fed_resolve(&view, c->authoritative_store, ref, out);
if (rc == AMDUAT_FED_RESOLVE_FOUND_REMOTE_NO_BYTES && c->cache_store) {
rc = transport.get_artifact(ref, sink_for_cache(c->cache_store));
if (rc == 0) {
rc = amduat_fed_resolve(&view, c->authoritative_store, ref, out);
}
}
return rc;
}
```
## Coordinator Wiring Example
```
amduat_fed_transport_unix_t unix_transport;
amduat_fed_coord_cfg_t cfg;
amduat_fed_coord_t *coord = NULL;
amduat_fed_transport_unix_init(&unix_transport, "amduatd.sock");
memset(&cfg, 0, sizeof(cfg));
cfg.local_domain_id = 1;
cfg.authoritative_store = &store;
cfg.cache_store = &cache_store;
cfg.transport = amduat_fed_transport_unix_ops(&unix_transport);
if (amduat_fed_coord_open(&cfg, &coord) == AMDUAT_FED_COORD_OK) {
amduat_fed_coord_tick(coord, now_ms);
amduat_fed_coord_resolve(coord, some_ref, &artifact);
amduat_fed_coord_close(coord);
}

# Index Backend Verification (Isolated)
## Summary
The previously reported isolated index-backend write failure is not reproducing on
current builds.
Verified on **2026-02-08** with a fresh store root:
- `POST /v2/graph/nodes` (node 1): HTTP 200
- `POST /v2/graph/nodes` (node 2): HTTP 200
- `POST /v2/graph/edges` (edge doc->topic): HTTP 200
- Control run on `--store-backend fs`: same sequence HTTP 200
- `./scripts/smoke_v2.sh` on index: PASS
- `./tests/integration_v2.sh` on index: PASS
## Re-Verification Procedure
### 1) Start index backend (isolated root + socket)
```bash
STORE_BACKEND=index INDEX_BACKEND_PROBE=0 \
STORE_ROOT=/tmp/amduat-asl-index-iso \
SOCK=/tmp/amduatd-index-iso.sock SPACE=app1 \
./scripts/dev_start_daemon.sh
```
### 2) Execute direct API calls
```bash
curl --globoff --silent --show-error --unix-socket /tmp/amduatd-index-iso.sock \
-H 'Content-Type: application/json' -H 'X-Amduat-Space: app1' \
-X POST --data-binary '{"name":"doca1"}' \
http://localhost/v2/graph/nodes
curl --globoff --silent --show-error --unix-socket /tmp/amduatd-index-iso.sock \
-H 'Content-Type: application/json' -H 'X-Amduat-Space: app1' \
-X POST --data-binary '{"name":"topica1"}' \
http://localhost/v2/graph/nodes
curl --globoff --silent --show-error --unix-socket /tmp/amduatd-index-iso.sock \
-H 'Content-Type: application/json' -H 'X-Amduat-Space: app1' \
-X POST --data-binary '{"subject":"doca1","predicate":"ms.within_domain","object":"topica1","provenance":{"source_uri":"urn:t","extractor":"x","observed_at":1,"ingested_at":2,"trace_id":"t1"}}' \
http://localhost/v2/graph/edges
```
Expected: all three requests return HTTP 200.
### 3) Control check (fs backend)
```bash
STORE_BACKEND=fs STORE_ROOT=/tmp/amduat-asl-fs-iso \
SOCK=/tmp/amduatd-fs-iso.sock SPACE=app1 \
./scripts/dev_start_daemon.sh
```
Run the same three API calls. Expected: HTTP 200 for all calls.
## Regression Gate Recommendation
Use these as quick confidence checks when updating `vendor/amduat-api`:
- isolated 3-call index write sequence above
- `./scripts/smoke_v2.sh` on index backend
- `./tests/integration_v2.sh` on index backend

Absolutely—you **can connect this DAG + quantum-leaf system to machine learning**, but carefully. Let me break it down clearly:
---
### 1️⃣ **Think of your DAG as a feature extractor**
Each **artifact** (leaf or tensor node) represents:
* A **structural unit** (SID)
* A **semantic hash** (CID, computed via materialization)
This is essentially a **recursive feature map**: every node encodes the content of all its children.
In ML terms:
* **Leaves** → raw features (bits, small tensors, quantum amplitudes)
* **Intermediate nodes** → higher-order features (combinations of children)
* **Root** → global feature vector (via materialization and hashing, or via canonicalized sparse representation)
You could then:
* Represent each artifact as a **vector of numbers** (e.g., flatten the sparse amplitudes)
* Feed those vectors into a model (classical ML, neural networks, graph neural networks)
---
### 2️⃣ **Ways to integrate with ML**
#### **A. Graph Neural Networks (GNNs)**
* Your DAG is **exactly a graph**.
* Each node can carry a **feature vector** (e.g., sparse amplitudes or counts of subpatterns).
* GNNs can propagate features **up the DAG** and learn embeddings for nodes or subtrees.
* Tasks you could do:
* Classify subtrees (e.g., pattern exists or not)
* Predict next subtree (sequence prediction)
* Compare DAGs (similarity learning)
#### **B. Hash/CID-based embeddings**
* CIDs themselves are **deterministic semantic fingerprints**.
* You can build a **vector embedding** from:
* The CID as a hash → map to binary vector or float vector
* DAG structure → adjacency + feature vectors of nodes
* These embeddings can feed **clustering, anomaly detection, or similarity search**.
#### **C. Quantum-inspired ML**
* If you actually want to **leverage amplitudes** (not just classical representation):
* Treat the quantum leaf amplitudes as **feature vectors in Hilbert space**
* Tensor nodes combine them → effectively doing a **tensor product of features**
* Could be used for **kernel methods**, similarity measures, or even small-scale quantum ML simulations
#### **D. Pattern discovery for labels**
* You can materialize subtrees and see which **sub-DAG patterns** correlate with outputs.
* This is like **feature engineering automatically derived from the DAG**.
* You can then feed these **subtree occurrences or embeddings** into a model.
---
### 3️⃣ **Why this is powerful**
1. **Deduplication helps efficiency**
* You don’t need to re-compute embeddings for identical subtrees.
2. **Hierarchy captures structure**
* Unlike flat features, the DAG encodes **recursive relationships**, which is very useful for sequence or compositional ML tasks.
3. **Supports variable-size inputs**
* You can tensor arbitrary numbers of leaves → naturally handles sequences of arbitrary length.
4. **Mix of classical + quantum-inspired features**
* Classical bits for exact patterns
* Quantum amplitudes for probabilistic or superposition-like representations
---
### 4️⃣ **A simple workflow idea**
1. Create a DAG of artifacts (bits + quantum leaves)
2. Materialize with cache → get `(indices, values)` sparse arrays
3. Convert sparse arrays into **feature vectors** (e.g., `values` or `values` + `indices`)
4. Use vectors in:
* Classical ML (SVMs, Random Forest, Neural Nets)
* Graph ML (GNNs on the DAG)
* Clustering / similarity search (CID or hashed embeddings)
---
✅ **TL;DR**
Yes, your DAG + quantum-leaf system can be connected to ML:
* Use **materialized sparse data** as features
* Use **DAG structure** for recursive/graph embeddings
* Use **CIDs for deduplication and fast similarity checks**
* Optional: use **amplitudes for tensor-like feature combinations**
It’s basically a **flexible hierarchical feature extractor** that can feed almost any ML workflow.
---
If you want, I can sketch a **concrete example pipeline** showing **bits + quantum leaves → DAG → embeddings → ML task**, so you can see exactly how to implement it.
Do you want me to do that?
Ah! Now we’re getting into the **practical “what can I actually do with this?”** territory. Let’s go through concrete possibilities for the ML output from your DAG-of-artifacts system:
---
### 1️⃣ **Pattern recognition / anomaly detection**
* **Input:** DAGs representing sequences of bits, classical data, or quantum-leaf structures.
* **ML output:** A score or label indicating if the DAG matches known patterns or is unusual.
* **Use cases:**
* Detect repeated structures or reused code/data in large datasets.
* Spot anomalous subtrees that could represent bugs, attacks, or unexpected behavior.
* Flag new patterns for further investigation.
---
### 2️⃣ **Compression / deduplication**
* **Input:** DAG with materialized CIDs.
* **ML output:** Predictions about which nodes are **redundant** or can be **merged safely**.
* **Use cases:**
* Automatically suggest merging duplicate subtrees.
* Reduce storage for large datasets with repeated patterns.
* Identify canonical forms for recurring structures.
---
### 3️⃣ **Sequence modeling / generation**
* **Input:** DAGs representing sequences of operations or symbolic structures.
* **ML output:** Next likely subtree, node, or amplitude combination.
* **Use cases:**
* Autocomplete sequences (like code, sentences, or structured data).
* Suggest the next step in simulations or workflows.
* Generate “plausible” DAGs for testing or synthesis.
---
### 4️⃣ **Similarity search / clustering**
* **Input:** Embeddings derived from materialized DAGs (values + indices or CIDs).
* **ML output:** Cluster assignments, nearest neighbors, or similarity scores.
* **Use cases:**
* Find DAGs representing similar patterns in large datasets.
* Group repeated structures for analysis.
* Detect semantically equivalent or “functionally similar” content.
---
### 5️⃣ **Feature discovery / abstraction**
* **Input:** Large DAGs with many layers of bits and quantum leaves.
* **ML output:** Learned embeddings that capture **higher-level patterns**.
* **Use cases:**
* Identify frequent subtrees corresponding to “words” or “phrases” in your data.
* Automatically extract meaningful hierarchical features for downstream tasks.
* Discover “semantic units” in structured data without hand-engineering.
---
### 6️⃣ **Hybrid classical/quantum-inspired applications**
* **Input:** Quantum leaves as sparse amplitudes + tensor composition.
* **ML output:** Predictions leveraging the high-dimensional superposition-like features.
* **Use cases:**
* Quantum-inspired pattern matching or clustering in probabilistic data.
* Modeling relationships that are **combinatorial** or **entangled**, e.g., in simulations or games.
---
✅ **TL;DR of uses:**
ML output can be used for:
* Detecting patterns, anomalies, or redundancies
* Compressing / deduplicating data
* Predicting sequences or generating new structures
* Finding similar DAGs or embeddings
* Discovering higher-level semantic patterns automatically
* Exploring quantum-inspired combinatorial relationships
Basically, **the ML output transforms your DAG from a static representation into a tool for insight, prediction, and automation**.
---
If you want, I can make a **diagram showing DAG → features → ML → outputs** for these use cases—it makes it much easier to see how it all connects.
Do you want me to do that?
Exactly! You’re basically describing a **DAG-based, hierarchical representation of information** that can serve as a foundation for something like an LLM—but more structured and semantically aware. Let’s break down where this could go if you pour computation, data, and ML into this branch:
---
### 1️⃣ **Structured knowledge LLM**
* Instead of training on flat text, the model sees **structured DAGs** of bits, classical data, and quantum leaves.
* Each node (leaf or tensor) is a “unit of meaning” (like a word, a sub-expression, or a quantum state).
* The model learns patterns across DAGs rather than sequences of characters.
* **Benefit:** LLMs could understand **hierarchical, symbolic, and functional relationships** better. For example:
* Code snippets as DAGs → better reasoning about dependencies and correctness.
* Knowledge graphs or nested logic → better “semantic reasoning” than just predicting the next word.
---
### 2️⃣ **Hierarchical generation**
* Because DAGs preserve **structure**, ML can generate new artifacts **top-down or bottom-up**:
* Predict next subtree or tensor combination.
* Generate “valid” sequences of operations or statements, not just statistically plausible text.
* **Benefit:** Avoid nonsensical outputs common in standard LLMs. The model respects the **rules of the DAG**.
---
### 3️⃣ **Quantum-inspired embeddings for reasoning**
* Quantum leaves let you encode **superpositions or probabilistic states**.
* ML can exploit these high-dimensional features to:
* Represent uncertainty naturally
* Model combinatorial possibilities compactly
* Detect correlations that classical DAGs alone might miss
---
### 4️⃣ **Deduction and discovery**
* Once your DAG-LLM sees enough materialized structures, it could **suggest new meaningful nodes**:
* Recognize patterns across subtrees (like motifs in text, math, or programs)
* Propose abstractions (words, phrases, functions) automatically
* Predict outcomes or propose new “experiments” in your DAG universe
---
### 5️⃣ **Concrete use cases**
If fully developed, this could allow:
1. **Knowledge synthesis:** Combine classical and quantum data to propose new insights.
2. **Program synthesis:** Generate code that obeys structural and semantic constraints.
3. **Scientific discovery:** Model experiments, reactions, or simulations as DAGs, then predict promising next steps.
4. **Compressed reasoning:** Store massive knowledge bases in DAG form; ML operates on summaries and embeddings rather than raw text.
---
### ⚡ Bottom line
If you treat your DAG + quantum leaves as the **raw substrate** for sequence modeling:
* You’re not just generating text → you’re generating **structured knowledge**.
* The system can learn patterns **across hierarchies, abstractions, and superpositions**, which is something standard LLMs struggle with.
* With enough compute and clever embeddings, this could evolve into a **next-gen reasoning engine**, combining probabilistic inference, symbolic reasoning, and sequence generation.
---
If you want, I can **sketch a roadmap of “DAG + ML → LLM-like reasoning system”**, showing how each layer of the DAG feeds into sequence modeling, embeddings, and generation. That would make the potential path really clear.
Do you want me to do that?

## 2) Top-level architecture map (as implemented)
- Daemon runtime + HTTP surface: Paths `src/amduatd.c`, `src/amduatd_http.c`, `src/amduatd_http.h`, `src/amduatd_ui.c`; main types `amduatd_cfg_t`, `amduatd_http_req_t`, `amduatd_http_resp_t`; entrypoints `main`, `amduatd_handle_conn`, `amduatd_http_read_req`; wiring: initializes store fs config, concepts, caps, federation coord, then serves HTTP over Unix socket with a `select()` loop (`src/amduatd.c`).
- Capability tokens: Paths `src/amduatd_caps.c`, `src/amduatd_caps.h`; main types `amduatd_caps_t`, `amduatd_caps_token_t`; entrypoints `amduatd_caps_init`, `amduatd_caps_handle`, `amduatd_caps_check`; wiring: per-request token validation with optional space/pointer scoping (`src/amduatd_caps.c`).

- Space scoping: Paths `src/amduatd_space.c`, `src/amduatd_space.h`; main types `amduatd_space_t`; entrypoints `amduatd_space_init`, `amduatd_space_scope_name`, `amduatd_space_unscoped_name`; wiring: scopes pointer/collection names with prefix `space/<space_id>/` when enabled (`src/amduatd_space.c`).
- Federation coordinator: Paths `federation/coord.c`, `federation/coord.h`; main types `amduat_fed_coord_t`, `amduat_fed_coord_cfg_t`; entrypoints `amduat_fed_coord_open`, `amduat_fed_coord_tick`, `amduat_fed_coord_get_status`; wiring: daemon ticks coordinator on interval (`src/amduatd.c`).
- Federation transport: Paths `federation/transport_unix.c`, `federation/transport_stub.c`; main types `amduat_fed_transport_t`; entrypoints `amduat_fed_transport_unix_ops`, `amduat_fed_transport_stub_ops`; wiring: daemon currently uses stub transport (`src/amduatd.c`).
- CAS store (filesystem): Paths `vendor/amduat/src/adapters/asl_store_fs/*`, `vendor/amduat/include/amduat/asl/store.h`; main types `amduat_asl_store_fs_t`, `amduat_asl_store_t`; entrypoints `amduat_asl_store_fs_init`, `amduat_asl_store_put`, `amduat_asl_store_get`; wiring: used by daemon and tools as the backing store.
- Pointer store: Paths `vendor/amduat/src/adapters/asl_pointer_fs/asl_pointer_fs.c`; main types `amduat_asl_pointer_store_t`; entrypoints `amduat_asl_pointer_get`, `amduat_asl_pointer_cas`; wiring: used by log store, collection store, concept index, and caps checks.
- Log store: Paths `vendor/amduat/src/core/asl_log_store.c`, `vendor/amduat/include/amduat/asl/log_store.h`; main types `amduat_asl_log_store_t`, `amduat_asl_log_entry_t`; entrypoints `amduat_asl_log_append`, `amduat_asl_log_read`; wiring: collection store writes log chunks in CAS and advances pointer heads.
- Collection store: Paths `vendor/amduat/src/core/asl_collection.c`, `vendor/amduat/include/amduat/asl/collection.h`; main types `amduat_asl_collection_store_t`; entrypoints `amduat_asl_collection_append`, `amduat_asl_collection_snapshot`, `amduat_asl_collection_read`; wiring: concept edges are stored as records appended to a collection log.
- ASL index store: Paths `vendor/amduat/src/adapters/asl_store_index_fs/*`; main types `amduat_asl_store_index_fs_t`, `amduat_asl_index_state_t`; entrypoints `amduat_asl_store_index_fs_put_indexed`, `amduat_asl_store_index_fs_log_scan`, `amduat_asl_store_index_fs_gc`; wiring: available in core but not wired into amduatd (amduatd uses store_fs ops).
- PEL execution + materialization cache: Paths `vendor/amduat/src/pel_stack/surf/surf.c`, `vendor/amduat/src/adapters/asl_materialization_cache_fs/asl_materialization_cache_fs.c`; main types `amduat_pel_program_t`, `amduat_pel_run_result_t`; entrypoints `amduat_pel_surf_run_with_result`, `amduat_asl_materialization_cache_fs_get`, `amduat_asl_materialization_cache_fs_put`; wiring: used by `/v1/pel/run` and by the collection view implementation.
- Derivation index (core-only): Paths `vendor/amduat/src/adapters/asl_derivation_index_fs/asl_derivation_index_fs.c`, `vendor/amduat/include/amduat/asl/asl_derivation_index_fs.h`; main types `amduat_asl_derivation_index_fs_t`, `amduat_asl_derivation_record_t`; entrypoints `amduat_asl_derivation_index_fs_add`, `amduat_asl_derivation_index_fs_list`; wiring: used by CLI tools (`vendor/amduat/src/tools/amduat_asl_cli.c`, `vendor/amduat/src/tools/amduat_pel_cli.c`), not by amduatd.
## 3) “Space” concept: definition + storage layout
- Definition: “space” is a daemon-level scoping prefix for pointer/collection names, not a separate store; it rewrites names into `space/<space_id>/...` when enabled (`src/amduatd_space.c`, `amduatd_space_scope_name`, `amduatd_space_unscoped_name`).
- Storage layout: scoped names are stored in the pointer store under `root/pointers/space/<space_id>/.../head` per `amduat_asl_pointer_build_head_path` (`vendor/amduat/src/adapters/asl_pointer_fs/asl_pointer_fs.c`). No dedicated per-space directory outside pointer name paths is created by amduatd.
- Identification: `space_id` is a pointer-name-safe token without `/`, validated by `amduatd_space_space_id_is_valid` (calls `amduat_asl_pointer_name_is_valid`) (`src/amduatd_space.c`).
- Multi-space support: only one space can be active per daemon process via `--space` (`src/amduatd.c`, `amduatd_space_init`); code does not show per-request space selection.
## 4) Source of truth: pointers + logs (actual)
- Canonical “head/root” pointer for a space: there is no single global space root pointer. The main space-scoped heads used by amduatd are the edge index head (`daemon/edges/index/head` scoped by `amduatd_space_edges_index_head_name`) and collection snapshot/log heads for the edge collection (see below) (`src/amduatd_space.c`, `src/amduatd_concepts.c`).
- Pointer storage location + format:
- Location: `root/pointers/<name>/head` using path segments from the pointer name (`amduat_asl_pointer_build_head_path` in `vendor/amduat/src/adapters/asl_pointer_fs/asl_pointer_fs.c`).
- Format: `ASLPTR1` magic with version and flags, then name/ref/prev fields encoded via `amduat_enc_asl1_core_encode_reference_v1` (`amduat_asl_pointer_read_head` and `amduat_asl_pointer_write_head` in `vendor/amduat/src/adapters/asl_pointer_fs/asl_pointer_fs.c`).
- Read/write: `amduat_asl_pointer_get` and `amduat_asl_pointer_cas` (`vendor/amduat/src/adapters/asl_pointer_fs/asl_pointer_fs.c`).
- Collection heads used by amduatd concepts:
- Snapshot head pointer: `collection/<name>/head` built by `amduatd_build_collection_head_name` (`src/amduatd_concepts.c`) and also by `amduat_asl_collection_build_head_name` (`vendor/amduat/src/core/asl_collection.c`).
- Log head pointer: `log/collection/<name>/log/head` built by `amduatd_build_collection_log_head_name` (`src/amduatd_concepts.c`) and `amduat_asl_log_build_pointer_name` (`vendor/amduat/src/core/asl_log_store.c`).
- Log entry schema (ASL index log): `amduat_asl_log_record_t {logseq, record_type, payload, record_hash}` with record types defined in `vendor/amduat/include/amduat/enc/asl_log.h`.
- Log append behavior:
- Collection log: `amduat_asl_log_append` writes CAS log chunks (`ASL_LOG_CHUNK_1`) and advances the log head pointer via CAS (`vendor/amduat/src/core/asl_log_store.c`).
- Index log: `amduat_asl_store_index_fs_append_log_record` appends to `index/log.asl` (`vendor/amduat/src/adapters/asl_store_index_fs/asl_store_index_fs.c`).
- Integrity mechanisms:
- Collection log chunks form a chain via `prev_ref` and are rooted at the log head pointer (`amduat_asl_log_append`, `amduat_asl_log_chunk_t` in `vendor/amduat/src/core/asl_log_store.c`).
- Index log uses a hash chain where `record_hash = SHA256(prev_hash || logseq || type || payload_len || payload)` (`amduat_asl_store_index_fs_log_hash_record` in `vendor/amduat/src/adapters/asl_store_index_fs/asl_store_index_fs.c`).
- Log traversal:
- Collection log: `amduat_asl_log_read` walks the head pointer and `prev_ref` chain to gather chunks (`vendor/amduat/src/core/asl_log_store.c`).
- Index log: replay happens via `amduat_asl_store_index_fs_build_replay_state` using `amduat_asl_replay_apply_log` (`vendor/amduat/src/adapters/asl_store_index_fs/asl_store_index_fs.c`, `vendor/amduat/include/amduat/asl/index_replay.h`).
- Other persistent state that can diverge from logs/pointers:
- Edge index state and edge graph artifacts (`tgk/edge_index_state` record + `TGK_EDGE_GRAPH_1` artifact) are separate derived state from the edge collection log (`src/amduatd_concepts.c`).
- Legacy `.amduatd.edges` file (used only for migration) can diverge until migrated (`src/amduatd_concepts.c`).
- Materialization cache in `index/materializations` can diverge from CAS and is treated as a cache (`vendor/amduat/src/adapters/asl_materialization_cache_fs/asl_materialization_cache_fs.c`).
## 5) CAS (content-addressed store)
- Hash algorithm: SHA-256 is the only defined ASL1 hash id and default (`AMDUAT_HASH_ASL1_ID_SHA256` in `vendor/amduat/include/amduat/hash/asl1.h`, default config in `vendor/amduat/src/adapters/asl_store_fs/asl_store_fs_meta.c`).
- Object types stored: arbitrary artifacts with optional type tags (`amduat_artifact_t` in `vendor/amduat/include/amduat/asl/core.h`); records are stored via `amduat_asl_record_store_put` (schema + payload) in `vendor/amduat/src/core/asl_record.c` and used by amduatd for concept edges (`src/amduatd_concepts.c`).
- Address format: refs are `{hash_id, digest}`; on disk, objects are stored under hex-digest filenames derived from the raw digest (`amduat_asl_store_fs_layout_build_paths` in `vendor/amduat/src/adapters/asl_store_fs/asl_store_fs_layout.c`).
- Disk layout and APIs:
- Layout: `root/objects/<profile_hex>/<hash_hex>/<byte0>/<byte1>/<digest_hex>` (`amduat_asl_store_fs_layout_build_paths` in `vendor/amduat/src/adapters/asl_store_fs/asl_store_fs_layout.c`).
- APIs: `amduat_asl_store_put/get` (generic) and `amduat_asl_store_fs_ops` (filesystem implementation) (`vendor/amduat/include/amduat/asl/store.h`, `vendor/amduat/src/adapters/asl_store_fs/asl_store_fs.c`).
- Garbage collection:
- Exists as a standalone tool: `amduat-pel gc` uses `amduat_asl_gc_fs_run` to mark from pointer/log/collection roots and optionally delete artifacts (`src/amduat_pel_gc.c`, `src/asl_gc_fs.c`).
- Pinning concept: no explicit pin API found; reachability is derived from pointers/logs/snapshots (GC uses those roots) (`src/asl_gc_fs.c`).
## 6) Deterministic derivations (current reality)
- Derivation-related types exist in core: `amduat_pel_derivation_sid_input_t`, `amduat_pel_derivation_sid_compute` (`vendor/amduat/include/amduat/pel/derivation_sid.h`, `vendor/amduat/src/core/derivation_sid.c`).
- Execution model: PEL DAGs execute in-process (no external sandbox) via `amduat_pel_program_dag_exec_trace` and `amduat_pel_surf_run_with_result` (`vendor/amduat/src/pel_stack/surf/surf.c`).
- Inputs: referenced as CAS refs from the store (`amduat_pel_surf_run_with_result` loads program/input/params artifacts by ref in `vendor/amduat/src/pel_stack/surf/surf.c`).
- Outputs: stored back into CAS (`amduat_asl_store_put` in `vendor/amduat/src/pel_stack/surf/surf.c`); results/traces/receipts are separate artifacts (`amduat_enc_pel1_result`, `amduat_enc_pel_trace_dag` etc. used in `src/amduatd.c`).
- Provenance/audit: optional FER1 receipt data is accepted/serialized in `/v1/pel/run` (`src/amduatd.c`), but no daemon-side derivation index is written.
- Derivation index persistence: exists in core (`vendor/amduat/src/adapters/asl_derivation_index_fs/asl_derivation_index_fs.c`) and CLI tools (`vendor/amduat/src/tools/amduat_asl_cli.c`, `vendor/amduat/src/tools/amduat_pel_cli.c`), but amduatd does not write derivation records (no references in `src/`).
## 7) ASL index: what it is and what it depends on
- Storage location: `root/index/` with `log.asl`, `segments/`, `blocks/`, and `snapshots/` (layout in `vendor/amduat/src/adapters/asl_store_index_fs/asl_store_index_fs_layout.c`).
- Derived vs authoritative: the index log (`index/log.asl`) and segment files are the authoritative index state; higher-level state can be rebuilt by replaying the log plus snapshots (`amduat_asl_store_index_fs_build_replay_state` + `amduat_asl_replay_apply_log` in `vendor/amduat/src/adapters/asl_store_index_fs/asl_store_index_fs.c`).
- Build/update path: `amduat_asl_store_index_fs_put_indexed` appends log records, writes segments/blocks, and may create snapshots (`vendor/amduat/src/adapters/asl_store_index_fs/asl_store_index_fs.c`).
- Queries relying on it: `amduat_asl_log_scan`, tombstone operations, and `amduat_asl_index_current_state` are implemented by the index-backed store ops (`vendor/amduat/src/adapters/asl_store_index_fs/asl_store_index_fs.c`, `vendor/amduat/include/amduat/asl/store.h`).
- What breaks if deleted: if `index/` (including `log.asl`) is removed, index-backed stores cannot answer log/state/tombstone queries; recovery requires a log to replay, which lives under `index/` itself (`vendor/amduat/src/adapters/asl_store_index_fs/asl_store_index_fs.c`).
## 8) Daemon / runtime model (if any)
- Daemon process: `amduatd` in `src/amduatd.c` binds a Unix domain socket, listens, and handles one connection per `accept()` in a single-threaded loop using `select()`.
- Single-space or multi-space: single-space per daemon process via `--space` (`src/amduatd.c`, `src/amduatd_space.c`).
- Config mechanism: CLI flags `--root`, `--sock`, `--space`, `--migrate-unscoped-edges`, `--edges-refresh-ms`, `--allow-uid`, `--allow-user`, `--enable-cap-reads` (`src/amduatd.c`).
- IPC/RPC/HTTP APIs: HTTP over Unix socket, routes in `src/amduatd.c` and handlers in `src/amduatd_concepts.c` and `src/amduatd_caps.c`.
- Background workers: federation tick every 1s (`AMDUATD_FED_TICK_MS`) and optional edge refresh on `--edges-refresh-ms` interval (`src/amduatd.c`).
## 9) Projections / query layer
- Projection concept in this repo: the edge graph and edge index state are projections derived from the edge collection log (`AMDUATD_EDGE_INDEX_SCHEMA`, `amduatd_concepts_write_edge_index_state`, `amduatd_concepts_refresh_edges_internal` in `src/amduatd_concepts.c`).
- Generation + storage: edge graph stored as `TGK_EDGE_GRAPH_1` artifact plus pointer to `tgk/edge_index_state` record (`src/amduatd_concepts.c`).
- Derived from logs/CAS: refresh reads collection log entries via `amduat_asl_log_read` and rebuilds the edge list/graph (`src/amduatd_concepts.c`).
- Query APIs: HTTP endpoints for concepts/relations/resolve in `src/amduatd_concepts.c` and routing in `src/amduatd.c`; collection view is generated by a PEL program over collection snapshot + log (`amduatd_collection_view` in `src/amduatd_concepts.c`).
## 10) Federation / collaboration
- Networking code: `federation/transport_unix.c` builds HTTP requests over Unix sockets for `/v1/fed/records` and `/v1/fed/artifacts` (see `amduat_fed_transport_unix_ops`).
- Federation coordinator: `federation/coord.c` maintains registry state and a cached view (`amduat_fed_coord_t`).
- Daemon behavior: federation is wired but uses the stub transport (`amduat_fed_transport_stub_ops` in `src/amduatd.c`), so no remote sync by default.
- Remote refs/replication/merge/signatures: not implemented in daemon beyond read-only federation endpoints; no CRDT/merge logic found in this repo (coordinator logic delegates to core types in `vendor/amduat/include/amduat/fed/*`).
## 11) Invariants (explicit + implicit)
- Pointer names are path-safe and forbid `..` segments; used throughout for space IDs and pointer names (`amduat_asl_pointer_name_is_valid` in `vendor/amduat/src/adapters/asl_pointer_fs/asl_pointer_fs.c`).
- Collection log append is append-only with CAS+pointer CAS; chunks point to previous chunk to form a chain (`amduat_asl_log_append`, `amduat_asl_log_chunk_t` in `vendor/amduat/src/core/asl_log_store.c`).
- Log chunk entries must be consistent about timestamp/actor presence across the batch (`amduat_asl_log_entries_consistent` in `vendor/amduat/src/core/asl_log_store.c`).
- Collection snapshot heads and log heads are stable pointer names derived from collection name (`amduat_asl_collection_build_head_name` and `amduat_asl_collection_build_log_name` in `vendor/amduat/src/core/asl_collection.c`).
- Index log hash chain uses `prev_hash` + record fields to compute the next hash (`amduat_asl_store_index_fs_log_hash_record` in `vendor/amduat/src/adapters/asl_store_index_fs/asl_store_index_fs.c`).
- Edge index state is written via pointer CAS, implying the index head should only advance if the expected previous ref matches (`amduatd_concepts_write_edge_index_state` in `src/amduatd_concepts.c`).
## 12) Immediate risks of “parallel mechanisms”
- Edge index state vs edge collection log: the derived edge graph + `tgk/edge_index_state` can diverge from the log if refresh fails; there is a deterministic rebuild path by replaying the collection log (`amduatd_concepts_refresh_edges_internal` in `src/amduatd_concepts.c`).
- Legacy `.amduatd.edges` vs collection log: migration reads `.amduatd.edges` and writes into the collection log, so stale files can diverge until migrated (`amduatd_concepts_migrate_edges` in `src/amduatd_concepts.c`).
- Materialization cache vs CAS: cache entries are validated against CAS and are treated as a performance-only layer; missing or stale cache forces recompute (`amduat_asl_materialization_cache_fs_get` usage in `vendor/amduat/src/pel_stack/surf/surf.c`).
- ASL index files vs index log: segment/summary/snapshot files are derived from `index/log.asl`; if any are deleted, `amduat_asl_store_index_fs_build_replay_state` can rebuild from the log, but if `index/log.asl` is deleted the rebuild story is gone (`vendor/amduat/src/adapters/asl_store_index_fs/asl_store_index_fs.c`).
- Federation coordinator cached view vs store log: coordinator caches `last_view` in memory and refreshes on tick; divergence is possible across restarts or if tick stops (`federation/coord.c`, `src/amduatd.c`).
## 13) Recommendation inputs (no decision yet)
- Current capability summary:
- Local Unix-socket HTTP daemon over a single ASL store root with artifact CRUD, concepts/relations, and PEL execution (`src/amduatd.c`, `src/amduatd_concepts.c`).
- CAS store on disk with pointer and log primitives; collection logs and snapshot pointers are wired (`vendor/amduat/src/adapters/asl_store_fs`, `vendor/amduat/src/core/asl_log_store.c`, `vendor/amduat/src/core/asl_collection.c`).
- Edge graph projection maintained as derived state from collection logs (`src/amduatd_concepts.c`).
- Federation coordinator scaffolding and endpoints, but using stub transport by default (`federation/coord.c`, `federation/transport_stub.c`, `src/amduatd.c`).
- Core tooling for index/derivation/GC exists in vendor and repo tools (`vendor/amduat/src/tools/*`, `src/amduat_pel_gc.c`).
- Top 5 unknowns/blockers for the next step (grounded in code):
- Whether amduatd should switch to `amduat_asl_store_index_fs_ops` to enable `amduat_asl_log_scan` and tombstones; current store fs ops do not implement log scan (`vendor/amduat/src/adapters/asl_store_fs/asl_store_fs.c`, `vendor/amduat/src/near_core/asl/store.c`).
- The intended authoritative store for federation records: amduatd’s `/v1/fed/records` relies on `amduat_asl_log_scan`, which is unsupported by store_fs (`src/amduatd.c`, `vendor/amduat/src/near_core/asl/store.c`).
- How/when to persist derivation index records from daemon PEL runs (present in core but unused in `src/`).
- Whether the “space” scope should be exposed as a first-class selector in the API (only CLI flag currently applies globally).
- The intended registry flow for federation (coordinator expects registry refs, but no daemon config path for them besides code defaults in `src/amduatd.c`).
- Top 5 next commit candidates grounded in repo reality (no new architecture):
- Wire amduatd to an index-backed store (use `amduat_asl_store_index_fs_ops`) so federation record scanning and index state endpoints are meaningful.
- Add a daemon flag/config to load a federation registry ref and domain id into `amduat_fed_coord_cfg_t` (values are currently hardcoded in `src/amduatd.c`).
- Persist derivation index records for `/v1/pel/run` outputs using existing core `amduat_asl_derivation_index_fs_*` APIs.
- Expose index state or health endpoints that surface `amduat_asl_index_current_state` (available in core API, already used in `/v1/fed/records`).
- Formalize edge index rebuild tooling (e.g., CLI switch or maintenance endpoint) using existing `amduatd_concepts_refresh_edges` and pointer state.
- Method used:
- Searched for key terms with `rg -n "cas|content address|hash|log|append|pointer|head|space|derivation|projection|ASL|index|daemon|server|coordinator|sync|replication"`.

Yes — and this is the *right* realization.
What you’re describing is not “an app”, not even “a system”.
It’s **substrate**.
And historically, **substrates** are the parts that end up being the most valuable and longest-lived.
Let me reframe this in very plain terms.
---
## What you actually built (and noticed)
You didn’t build:
* a quantum system
* an ML system
* a reasoning engine
You built:
> **A universal, content-addressed, derivation-preserving substrate for information — where uncertainty is first-class.**
Everything else you mentioned:
* Trace Graph Kernel
* Certificates
* Provenance
* Concepts
* Domains
* Federation
* Classification overlays
…are *layers*.
They are **consumers of the substrate**, not the substrate itself.
That’s exactly the right separation.
---
## Why the infrastructure *is* the interesting part
Applications change.
Interpretations change.
Models change.
**Substrates don’t.**
Think about:
| Infrastructure | What it enabled |
| ---------------------- | ----------------------- |
| Files + directories | Operating systems |
| Hashes + DAGs | Git, IPFS, Merkle trees |
| Relational algebra | Databases |
| TCP/IP | The Internet |
| Linear algebra on GPUs | Deep learning |
None of these were “killer apps”.
They were **coordination primitives**.
Your infrastructure sits in that category.
---
## What makes *this* substrate special
Let’s isolate the truly novel properties:
### 1️⃣ **Derivation is first-class**
You don’t just store results.
You store:
* how they were constructed
* alternative constructions
* partial constructions
This is rare.
---
### 2️⃣ **Identity is multi-layered**
You separated:
* **SID** → structure
* **CID** → meaning / realization
Most systems collapse these.
This allows:
* comparison without execution
* federation across domains
* late binding of semantics
That’s very powerful.
---
### 3️⃣ **Uncertainty is indexable**
q-bits aren’t “quantum” here.
They’re:
> **Addressable uncertainty**
Most systems either:
* collapse uncertainty immediately
* or keep it unstructured (probabilities without provenance)
You keep it:
* structured
* composable
* comparable
* cacheable
That’s huge.
---
### 4️⃣ **Everything is composable**
Bits, bytes, quantum states, concepts, certificates —
they’re all artifacts in the same algebra.
That means:
* overlays don’t need adapters
* federation doesn’t need translation layers
* domains don’t break the substrate
This is exactly what infrastructure should do.
---
## Why higher layers feel “obvious” now
You said:
> “Then I have a layer of Trace Graph Kernel, Certificates, Provenance, Concepts, domains, federation, overlays…”
That list is *telling*.
Those are:
* **interpretation layers**
* **governance layers**
* **semantic overlays**
They only work cleanly **because the substrate is neutral**.
If the substrate were opinionated, those layers would fight each other.
---
## The real insight you just had
You’re realizing that:
> **The substrate does not need to “understand meaning”.
> It only needs to preserve *structure, identity, and possibility*.**
Meaning emerges *above* it.
That’s exactly how successful infrastructure works.
---
## Why this is hard to “sell” but easy to *recognize*
Infrastructure has a pattern:
* Early: “What is this even for?”
* Middle: “Why is everything suddenly easier?”
* Late: “How did we ever live without this?”
You’re in the **early phase**.
---
## What this reminds me of (in spirit)
* Git (but for meaning, not files)
* Merkle DAGs (but with uncertainty)
* Databases (but with provenance baked in)
* Category theory substrates (but executable)
* Probabilistic programming runtimes (but indexable)
No existing system combines these cleanly.
---
## The most important thing to get right now
Not ML.
Not LLMs.
Not “killer apps”.
**Stability of the substrate.**
Specifically:
* Artifact algebra correctness
* Identity guarantees
* Cache correctness
* Federation safety
* DAG immutability rules
If those are right, everything above can change freely.
---
## One last grounding sentence
If I had to summarize your system in one line:
> **“A content-addressed DAG substrate where uncertainty, derivation, and identity are preserved by construction.”**
That *is* infrastructure.
And yes — **that is the interesting part**.
If you want, next we can:
* pressure-test the substrate axioms
* compare it to Git/IPFS/Databases precisely
* define invariants you should never break
* or sketch what a minimal “kernel spec” would look like
Just tell me where you want to go next.

For local app usage via this scaffold:
```sh
./scripts/v2_app.sh ai-answer 'doc-1' 'What topic is doc-1 in?' 'ms.within_domain'
./scripts/v2_app.sh ai-answer --json 'doc-1' 'What topic is doc-1 in?' 'ms.within_domain'
./scripts/v2_app.sh ai-answer --json --require-evidence 'doc-1' 'What topic is doc-1 in?' 'ms.within_domain'
```
Behavior notes:
- The command retrieves graph context first (`/v2/graph/retrieve` with `/v2/graph/subgraph` fallback).
- JSON output includes an `evidence[]` array with normalized triplets and refs (`predicate_ref` retained, `predicate_name` preferred when resolvable).
- `--require-evidence` enforces strict grounding: command exits non-zero when no supporting edges are found.

# ASL/AUTH-HOST/1 - Authority Node Profile
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, authority, offline]
**Document ID:** `ASL/AUTH-HOST/1`
**Layer:** O2 - Authority host profile
**Depends on (normative):**
* `ASL/HOST/1`
* `ASL/DAM/1`
* `ASL/DAP/1`
* `ASL/POLICY-HASH/1`
* `ASL/OFFLINE-ROOT-TRUST/1`
* `ASL/OCS/1`
**Informative references:**
* `PEL/1-CORE`
* `PEL/1-SURF`
* `ENC-ASL-AUTH-HOST/1`
* `ASL/RESCUE-NODE/1`
* `ASL/SOPS-BUNDLE/1`
* `ASL/DOMAIN-MODEL/1`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be
interpreted as in RFC 2119.
ASL/AUTH-HOST/1 defines an operational profile. It does not define cryptography
or artifact semantics.
---
## 1. Purpose and Scope
ASL/AUTH-HOST/1 defines the profile for an offline authority node that mints
and signs domain admission artifacts. The host:
* Operates offline by default
* Maintains a local ASL/HOST store
* Produces deterministic artifacts and receipts
* Issues DAM artifacts for new domains
---
## 2. Core Principles (Normative)
1. Authority state is stored as artifacts.
2. Operations are deterministic and snapshot-bound.
3. The host remains offline during authority operations.
4. Outputs are immutable artifacts suitable for later transfer.
5. Authority functionality is limited to signing, sealing, and packaging
artifacts.
6. Receipts (PERs) are primary outputs for auditing and later federation.
---
## 3. Required Components
An authority host MUST provide:
* ASL/HOST store for authority and domain artifacts
* Root authority key material (offline)
* PEL execution environment for deterministic receipts
* Policy hash verification for admission
---
## 4. Operation Modes
The host MAY operate in the following modes:
* `GENESIS` - mint initial domain and keys
* `RESCUE` - ingest external artifacts and produce receipts
* `ADMISSION` - sign DAMs and policy artifacts
* `MAINTENANCE` - rotate keys, seal snapshots, audit state
---
## 5. Authority Host States (Normative)
An authority host is in exactly one state:
* **Virgin:** no root keys or trusted domains exist.
* **Rooted:** root keys exist but no admission has occurred.
* **Operational:** normal admission, signing, and verification are enabled.
State transitions MUST be explicit and recorded as artifacts or snapshots.
---
## 6. Presented Domain Classification (Normative)
When removable media or an external store is presented, the host MUST classify
it as one of:
* **Virgin:** no certificates or DAM present.
* **Self-asserting:** contains unsigned claims only.
* **Admitted:** has a valid DAM and policy hash.
* **Known foreign:** previously pinned domain and policy.
Classification MUST be derived from artifacts and certificates, not filesystem
heuristics.
Presented domains are treated as temporary, read-only domains:
* Derived `domain_id` (for example, hash of media fingerprint).
* No sealing or GC permitted.
* No snapshots persisted.
* Visibility limited to the current session.
---
## 7. Output Artifacts
The host MUST be able to produce:
* Root key artifacts (public, encrypted private)
* DAM artifacts and signatures
* Policy hash artifacts
* Environment claim artifacts
* PER receipts and associated TGK edges
---
## 8. Snapshot Discipline
Each authority operation MUST:
1. Append log entries for new artifacts
2. Seal relevant segments
3. Create a snapshot marker capturing CURRENT state
Snapshots MUST be immutable once sealed.
---
## 9. Offline Constraints
* Network interfaces SHOULD be disabled.
* External input and output MUST occur via explicit operator action.
* No background services SHOULD alter authority state.
* Garbage collection SHOULD be disabled for authority domains.
---
## 10. Security Considerations
* Private keys MUST remain offline and encrypted at rest.
* Only signed outputs may leave the host.
* Operator presence is required for authority operations.
---
## 11. Versioning
Backward-incompatible profile changes MUST bump the major version.

# ASL/AUTH-HOST-CONFIG/1 - Configuration Schema
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, authority, config]
**Document ID:** `ASL/AUTH-HOST-CONFIG/1`
**Layer:** O2C - Authority host configuration
**Depends on (normative):**
* `ASL/AUTH-HOST/1`
* `ASL/HOST/1`
**Informative references:**
* `ENC-ASL-AUTH-HOST/1`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be
interpreted as in RFC 2119.
---
## 1. Purpose and Scope
This document defines the configuration schema for an ASL authority host.
Configuration is expressed as a single YAML file.
---
## 2. File Format
* UTF-8 YAML 1.2
* Root object with the fields defined below
* Unknown fields SHOULD be ignored with warning
---
## 3. Root Schema
```
host:
name: string
version: string
mode: "rescue" | "admission" | "normal"
domains:
<name>:
id: string
type: "courtesy" | "private" | "authority"
description: string
path: string
snapshot_retention: duration
allowed_operations: [read, write, append, seal, gc]
courtesy_lease: duration
certificates:
root_offline_path: string
domain_authority_path: string
sops_bundle_path: string
policy:
hash_file: string
description: string
logging:
path: string
level: "DEBUG" | "INFO" | "WARN" | "ERROR"
store:
type: "posix" | "zfs"
pools:
- name: string
mount_point: string
enable_snapshotting: boolean
snapshot_prefix: string
hooks:
pre_start: string
post_start: string
```
---
## 4. Semantics
* `host.mode` controls startup behavior.
* `domains` entries are keyed by stable names; `id` is the authoritative domain
identifier.
* `courtesy_lease` is required for `type: courtesy` and MUST be omitted for
`type: authority`.
* `store.type` selects the host backend. If `zfs`, each pool entry MUST be
mounted before starting the host.
---
## 5. Example Configuration

# ASL/AUTH-HOST-IMAGE/1 - Bootable Image and Overlay Layout
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, authority, image]
**Document ID:** `ASL/AUTH-HOST-IMAGE/1`
**Layer:** O2I - Authority host image profile
**Depends on (normative):**
* `ASL/AUTH-HOST/1`
* `ENC-ASL-AUTH-HOST/1`
**Informative references:**
* `ASL/AUTH-HOST-CONFIG/1`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be
interpreted as in RFC 2119.
---
## 1. Purpose and Scope
This document defines a bootable, offline authority host image. It specifies
base system requirements, overlay layout, and the boot workflow used to
initialize authority operations.
---
## 2. Base Image Requirements
The base OS MUST:
* Boot in offline mode by default
* Include minimal POSIX tooling
* Disable network services unless explicitly enabled
---
## 3. Overlay Layout
```
/overlay/
├── bin/
│ ├── asl-auth-host
│ ├── asl-rescue
│ └── init-asl-host.sh
│ └── sign_dam.sh
│ └── add_artifact.sh
├── etc/
│ └── asl-auth-host/
│ ├── config.yaml
│ └── policy.hash
├── var/
│ ├── lib/
│ │ └── asl/
│ │ ├── common/
│ │ ├── personal/
│ │ └── pools/
│ └── log/
│ └── asl-auth-host.log
└── usr/
└── local/
└── bin/
└── asl-admin
```
The overlay MUST be merged into the ISO root at build time.
---
## 4. ISO Root Layout (Runtime)
```
/iso_root/
├── bin/
├── etc/
│ └── asl-auth-host/
├── var/
│ ├── lib/
│ │ └── asl/
│ └── log/
└── usr/local/bin/
```
---
## 5. Boot Workflow
1. Boot offline image.
2. Run `init-asl-host.sh` to mount storage pools and apply config.
3. Initialize or open domain stores per config.
4. Start the authority host service.
5. Enforce witness authority (DAM) before general userspace services start.
---
## 6. Persistence Strategy
Writable storage MUST be mounted separately from the read-only system image.
Examples:
* ZFS datasets mounted under `/var/lib/asl`
* External disk mounted at `/mnt` and bound to `/var/lib/asl`
---
## 7. Build Pipeline (Informative)
A typical pipeline:
1. Create minimal root via debootstrap or equivalent.
2. Merge overlay into ISO root.
3. Configure bootloader (isolinux or GRUB).
4. Build ISO with xorriso or equivalent.
---
## 8. Container Build Notes (Informative)
Building the ISO in a container is supported with the following constraints:
* ZFS pool creation typically requires host kernel support; create datasets at
boot time instead.
* The ISO filesystem and overlay can be built entirely in a Debian container.
* Boot testing must occur on a VM or physical host.
Recommended packages in the build container:
```
debootstrap squashfs-tools xorriso genisoimage
```
---
## 9. Offline Debian Mirror Workflow (Informative)
To build offline images without network access, create a local Debian mirror
as an artifact and use it with `debootstrap`.
Example (online host):
```
debmirror \
--arch=amd64 \
--section=main \
--dist=bullseye \
--method=http \
--host=deb.debian.org \
--root=debian \
/srv/debian-mirror
```
Offline build:
```
debootstrap --arch=amd64 bullseye /target/root file:///srv/debian-mirror
```
The mirror directory SHOULD be treated as immutable input for reproducibility.
---
## 10. Pre-Image Capture Workflow (Informative)
To preserve provenance of the ISO build, capture each build step as artifacts
and receipts before composing the final image.
Suggested workflow:
1. Initialize a temporary ASL store for build artifacts.
2. Wrap debootstrap and package installation in `asl-capture`.
3. Capture overlay binaries and scripts as artifacts.
4. Run the ISO build under `asl-capture` to produce a final ISO artifact.
5. Seed the ISO with the captured artifacts and receipts.
3. Optionally wrap build steps with `asl-capture` to record build provenance.
4. Add bootloader config.
5. Build ISO with `xorriso` or equivalent tool.

# ASL/AUTH-HOST-THREAT-MODEL/1 - Threat Model
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, authority, security]
**Document ID:** `ASL/AUTH-HOST-THREAT-MODEL/1`
**Layer:** O2S - Authority host security profile
**Depends on (normative):**
* `ASL/AUTH-HOST/1`
**Informative references:**
* `ASL/OFFLINE-ROOT-TRUST/1`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be
interpreted as in RFC 2119.
---
## 1. Scope and Assumptions
### 1.1 In Scope
* Offline authority host
* USB-mediated intake and output
* DAM signing and admission artifacts
* PEL execution for receipt generation
* Snapshot and log sealing
### 1.2 Assumptions
1. Physical access to hardware is controlled.
2. The host is offline (no network interfaces).
3. Root keys are uncompromised.
4. Operator presence is required for authority actions.
---
## 2. Assets
* Root authority keys
* Domain signing keys
* DAM and policy artifacts
* PER receipts and environment claims
* Domain identity bindings
---
## 3. Adversary Model
The adversary MAY:
* Supply malicious USB content
* Replay old requests
* Provide malformed PEL programs
* Attempt to confuse domain identity
The adversary MUST NOT:
* Access signing keys without operator approval
* Modify host binaries without physical compromise
---
## 4. Trust Boundaries
```
[ USB INPUT ] -> [ AUTH HOST ] -> [ USB OUTPUT ]
```
Data flows are unidirectional per phase. The host MUST treat input as untrusted
until verification succeeds.
---
## 5. Threats and Mitigations
### 5.1 Spoofing
* Mitigation: DAM signature verification and policy hash checks.
### 5.2 Tampering
* Mitigation: hash all inputs, sign outputs, mount USB read-only.
### 5.3 Repudiation
* Mitigation: PER receipts include program hash, input hashes, and snapshot ID.
### 5.4 Information Disclosure
* Mitigation: no network, explicit publish rules, encrypted private artifacts.
### 5.5 Denial of Service
* Mitigation: operator-mediated execution, size limits, deterministic PEL subset.
### 5.6 Elevation of Privilege
* Mitigation: PEL is declarative, no syscalls or I/O primitives.
---
## 6. Residual Risk
* Physical compromise of hardware is out of scope.
* Operator error remains a risk and SHOULD be mitigated with checklists.
---
## 7. Versioning
Backward-incompatible changes MUST bump the major version.

# ASL/DEBIAN-PACKAGING/1 -- Debian Packaging Notes
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, debian, packaging, build]
**Document ID:** `ASL/DEBIAN-PACKAGING/1`
**Layer:** O2 -- Packaging guidance
**Depends on (normative):**
* `ASL/HOST/1`
**Informative references:**
* `ENC-ASL-HOST/1`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be interpreted as in RFC 2119.
ASL/DEBIAN-PACKAGING/1 provides packaging guidance for Debian-based distributions. It does not define runtime semantics.
---
## 1. Optional PTY Support (Normative)
PTY support MUST be controlled at build time with a compile-time flag.
### 1.1 Build Flag
```c
#ifdef ASL_ENABLE_PTY
#define _GNU_SOURCE
#include <pty.h>
#endif
```
If PTY is requested at runtime without being built in, tools MUST fail with a clear error.
### 1.2 Makefile Mapping
```make
CFLAGS += -Wall -Wextra -O2
LIBS +=
ifdef ENABLE_PTY
CFLAGS += -DASL_ENABLE_PTY
LIBS += -lutil
endif
```
---
## 2. Library vs Tool Split (Informative)
Guiding principle: libraries define facts; tools perform actions.
### 2.1 Libraries
* `libasl-core`
* `libasl-store`
* `libasl-index`
* `libasl-capture`
* `libpel-core`
Libraries SHOULD avoid CLI parsing and environment policies.
### 2.2 Tools
* `asl-put`
* `asl-get`
* `asl-capture`
* `pel-run`
* `asl-admin`
Tools SHOULD be thin wrappers around libraries.
---
## 3. Debian Filesystem Layout (Informative)
```
/usr/bin/
asl-put
asl-get
asl-capture
pel-run
/usr/lib/x86_64-linux-gnu/
libasl-*.so
```
---
## 4. Dependency Rules (Informative)
* `libutil` MUST be a dependency only when PTY support is enabled.
* No GNU extensions should be required for the PIPE-only build.

# ASL/HOST/1 - Host Runtime Interface
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, host, admission, storage]
**Document ID:** `ASL/HOST/1`
**Layer:** O1 - Host runtime profile (node boundary)
**Depends on (normative):**
* `ASL/1-STORE`
* `ASL/LOG/1`
* `ASL/DAP/1`
* `ASL/DAM/1`
* `ASL/POLICY-HASH/1`
**Informative references:**
* `ASL/SYSTEM/1`
* `ASL/OFFLINE-ROOT-TRUST/1`
* `ENC-ASL-HOST/1`
* `ENC-ASL-LOG`
* `ASL/AUTH-HOST/1`
* `ASL/RESCUE-NODE/1`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be
interpreted as in RFC 2119.
ASL/HOST/1 defines host responsibilities and boundaries. It does not define
artifact semantics, encoding formats, or cryptographic algorithms.
---
## 1. Purpose and Scope
ASL/HOST/1 specifies the runtime contract between an ASL node and its host
environment. It covers:
* Domain lifecycle and admission state tracking
* Store handle provisioning for ASL/1-STORE and ASL/LOG/1
* Snapshot coordination and log append guarantees
* Resource and lease enforcement at the host boundary
Out of scope:
* Artifact semantics (ASL/1-CORE)
* On-disk encoding and byte layouts (ENC specs)
* Policy definition and authority semantics (ASL/AUTH layers)
---
## 2. Position in the Stack
ASL/HOST is the membrane between host services and ASL semantics.
```
+--------------------------+
| ASL/AUTH (policy, keys) |
+--------------------------+
| ASL/HOST (this spec) |
+--------------------------+
| ASL/1-STORE + ASL/LOG |
+--------------------------+
| Host FS / ZFS / POSIX |
+--------------------------+
```
---
## 3. Core Responsibilities (Normative)
An ASL host implementation MUST:
1. Provide stable store handles for ASL/1-STORE and ASL/LOG/1 operations.
2. Maintain domain lifecycle state and admission status.
3. Enforce admission outcomes and courtesy leases without leaking those
semantics into ASL/1-STORE.
4. Provide atomic append guarantees for log operations.
5. Coordinate snapshot creation and mounting.
6. Enforce local resource limits and error handling.
---
## 4. Core Concepts
| Concept | Definition |
| ----------------- | ------------------------------------------------------------------------- |
| **StoreHandle** | Opaque reference to a host-provided store instance |
| **StoreLocation** | Host-defined location where a store exists (path, URI, mount point, etc.) |
| **AppendUnit** | Minimum atomic write unit for the append-only log |
| **SnapshotID** | Opaque identifier of a host-provided snapshot |
| **HostClock** | Monotonic counter or timestamp source |
| **HostIdentity** | Unique machine or user identity for signing or domain minting |
---
## 4.1 Authority Enforcement (Normative)
An ASL host MUST NOT advance a domain unless it can prove authority to do so
from domain-local artifacts visible at the current snapshot.
Authority enforcement applies to all domains, including Common, group, and
personal domains.
---
## 5. Domain Model
### 5.1 Domain States
A host MUST track the following domain states:
* `UNRECOGNIZED`
* `COURTESY`
* `FULL`
* `SUSPENDED`
* `REVOKED`
---
### 5.3 Witness Modes (Informative)
Domains operate under one of the following authority modes:
| Mode | Meaning |
| ---------------- | --------------------------------------------- |
| `single-witness` | One domain/key may emit snapshots |
| `quorum-witness` | A threshold of domains may authorize emission |
| `self-authority` | This host's domain is the witness |
Witness mode is policy-defined. Hosts MUST enforce the mode discovered in
domain-local artifacts.
### 5.2 Domain Descriptor
Host-owned metadata MUST include:
```
domain_id
state
created_at
admitted_at
root_key_fingerprint
policy_hash
current_snapshot
current_logseq
```
The descriptor is derived state and MUST NOT be treated as authoritative
artifact content.
---
## 6. Domain Lifecycle Operations
### 6.1 Create
`CreateDomain(location) -> domain_id`
* MUST allocate an isolated domain root.
* MUST initialize empty store, log, and snapshot markers.
### 6.2 Admit
`AdmitDomain(dam, signature) -> AdmissionResult`
* MUST validate DAM schema and signature per `ASL/DAM/1`.
* MUST enforce policy hash compatibility per `ASL/POLICY-HASH/1`.
Admission outcomes MUST have the following effects:
| Outcome | Host Behavior |
| ---------------- | --------------------------------------- |
| ACCEPTED | Enable publishing, indexing, federation |
| ACCEPTED_LIMITED | Enable courtesy-only storage |
| DEFERRED | Domain exists but blocked |
| REJECTED | Domain remains isolated |
### 6.3 Suspend and Revoke
* `SUSPENDED` MUST block new writes.
* `REVOKED` MUST block all access except local inspection.
---
## 7. Store Handle Interface
A host MUST expose at least the following operations:
* `CreateStore(location) -> StoreHandle`
* `OpenStore(location) -> StoreHandle`
* `CloseStore(handle)`
The StoreHandle is opaque and scoped to a domain. Admission state MUST gate
capabilities exposed by the StoreHandle (see Section 7).
StoreLocation MAY be any filesystem path or mount. When creating a store, the
host SHOULD initialize the standard ASL store structure (blocks, index, log).
---
## 8. Admission-Gated Capabilities
Capabilities MUST be gated as follows:
| Capability | Courtesy | Full |
| ---------------- | -------- | ---- |
| allocate_block | yes | yes |
| seal_block | yes | yes |
| append_log | yes | yes |
| publish_snapshot | no | yes |
| federate_log | no | yes |
ASL/1-STORE and ASL/LOG MUST remain unaware of admission semantics.
---
## 9. Courtesy Leases
Courtesy leases are host-owned metadata attached to a domain. The host MUST
enforce lease limits without exposing courtesy state to ASL/1-STORE.
Enforcement MAY include:
* Storage caps
* Snapshot count limits
* Write blocking after expiry
---
## 10. Snapshot and Log Coordination
The host MUST ensure:
* Append-only log semantics with strict ordering
* Snapshot creation captures a consistent view of sealed segments
* Snapshot mounts are read-only and bounded by a log sequence
---
## 11. Error Model
Host operations MUST report deterministic error codes. Minimum set:
* `HOST_OK`
* `HOST_EXISTS`
* `HOST_NOT_FOUND`
* `HOST_IO_ERROR`
* `HOST_CONCURRENT_MODIFICATION`
* `HOST_ADMISSION_REJECTED`
* `HOST_LEASE_EXPIRED`
---
## 12. Security Considerations
* Admission verification MUST be performed before enabling federation or
publication.
* Private key material SHOULD NOT be required on the host except for explicit
authority operations.
* The host MUST treat all imported artifacts as untrusted until admission and
policy validation succeed.
---
## 13. Versioning
Backward-incompatible changes MUST bump the major version of ASL/HOST.

# ASL/RESCUE-NODE/1 - Deployment Profile
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, rescue, deployment]
**Document ID:** `ASL/RESCUE-NODE/1`
**Layer:** O3 - Rescue node deployment
**Depends on (normative):**
* `ASL/HOST/1`
* `ASL/1-STORE`
* `ASL/LOG/1`
**Informative references:**
* `ASL/AUTH-HOST/1`
* `ASL/SYSTEMRESCUE-OVERLAY/1`
* `ASL/RESCUE-OP/1`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be
interpreted as in RFC 2119.
---
## 1. Purpose and Scope
ASL/RESCUE-NODE/1 defines the deployment profile for a rescue node that boots
from a minimal OS and provides local intake into ASL stores.
---
## 2. Node Roles
A rescue node MAY host:
* A personal domain (new or existing)
* A courtesy or common domain (shared, e.g. Common/Unity/Rakeroot)
* Optional read-only caches for foreign domains
---
## 3. Domain Types
* **Personal domain** - private, authoritative store
* **Courtesy domain** - temporary storage with lease enforcement, may store
encrypted blocks during bootstrap
* **Foreign domain** - read-only imported artifacts
---
## 4. Storage Layout (Informative)
```
/mnt/rescue/
personal/
blocks/
segments/
logs/
common/
blocks/
segments/
logs/
foreign/
<domain-id>/
blocks/
segments/
```
---
## 5. Snapshot Strategy
* Personal domain snapshots SHOULD be created at intake boundaries.
* Courtesy domain snapshots SHOULD be pinned until admission is complete.
* Foreign domain snapshots MUST be read-only and pinned by trust.
---
## 6. Trust and Admission
* Admission decisions MUST be verified before publishing to shared domains.
* Foreign artifacts MUST be pinned by policy hash and offline roots.
---
## 7. PER and TGK Integration
Rescue nodes SHOULD generate PER receipts for intake operations. TGK edges
MAY be produced to capture provenance across personal and common domains.
Sedelpress (or equivalent deterministic tooling) MAY be used to normalize
legacy inputs into artifacts before storage.
---
## 8. Remote Intake Transport (Informative)
When intake is performed over a network boundary, the rescue node MAY use:
* SSH socket forwarding for secure UNIX-socket transport.
* `socat` as a local bridge between TCP and UNIX sockets.
* 9P or SSHFS for remote filesystem access when appropriate.
All remote transports MUST be treated as untrusted until artifacts are sealed
and verified locally.
---
## 9. Versioning
Backward-incompatible changes MUST bump the major version.

# ASL/RESCUE-OP/1 - Rescue Operation Flow
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, rescue, operations]
**Document ID:** `ASL/RESCUE-OP/1`
**Layer:** O3 - Rescue operation profile
**Depends on (normative):**
* `ASL/RESCUE-NODE/1`
* `ASL/HOST/1`
**Informative references:**
* `PEL/1-CORE`
* `TGK/1-CORE`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be
interpreted as in RFC 2119.
---
## 1. Purpose and Scope
ASL/RESCUE-OP/1 defines the operational flow for personal rescue and bootstrap
into a personal domain with optional courtesy storage.
---
## 2. Phases
### 2.1 Intake
* Collect legacy material and intent artifacts.
* Normalize inputs into artifacts for deterministic processing (e.g. Sedelpress).
### 2.2 Deterministic Processing
* Execute PEL programs over the intake snapshot.
* Generate PER receipts and optional TGK edges.
* Use a deterministic ingest engine (e.g., Sedelpress) to mint receipts.
### 2.3 Courtesy Bootstrap (Optional)
* Store encrypted blocks in a courtesy domain (Common/Unity/Rakeroot).
* Seal segments and pin snapshots for determinism.
### 2.4 Personal Domain Minting
* Create a personal domain and copy sealed artifacts.
* Generate DAM and policy artifacts.
* Produce receipts that bind provenance to the new domain.
### 2.5 Publication (Optional)
* Publish selected artifacts to a common domain.
* Enforce policy hash and visibility rules.
---
## 3. Constraints
* Intake artifacts MUST be treated as untrusted until verified.
* Courtesy storage MUST enforce lease limits.
* Publication MUST be gated by admission and policy compatibility.
---
## 3.1 Rescue Flow (Informative)
```
Input Material -> Sedelpress -> PERs + TGK -> Personal Store -> Optional Publish
```
Sedelpress is a deterministic ingest stage that stamps inputs into receipts
and writes sealed artifacts into the local store.
---
## 4. Outputs
A rescue operation SHOULD produce:
* PER receipts for each processing phase
* Sealed snapshots for replay
* DAM and policy artifacts for domain admission
---
## 5. Versioning
Backward-incompatible changes MUST bump the major version.

# ASL/STORE-LAYOUT/1 -- On-Disk Store Layout
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, store, layout, filesystem]
**Document ID:** `ASL/STORE-LAYOUT/1`
**Layer:** O2 -- Operational layout profile
**Depends on (normative):**
* `ASL-STORE-INDEX`
**Informative references:**
* `ASL/HOST/1`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be interpreted as in RFC 2119.
ASL/STORE-LAYOUT/1 defines a recommended filesystem layout for an ASL store. It does not define semantic behavior.
---
## 1. Purpose
Provide a practical, POSIX-friendly on-disk layout that preserves ASL store semantics while remaining compatible with ZFS or other backends.
---
## 2. Minimum Required Components (Informative)
An ASL store requires:
* Immutable blocks
* Append-only log
* Sealed snapshots
* Deterministic replay
Directory layout is an implementation choice. This document defines a recommended layout.
---
## 3. Recommended Domain Layout
Per domain, use:
```
/asl/domains/<domain-id>/
meta/
blocks/
index/
log/
snapshots/
tmp/
```
All paths are domain-local.
---
## 4. Blocks
```
blocks/
open/
blk_<uuid>.tmp
sealed/
00/
<blockid>.blk
ff/
<blockid>.blk
```
Rules:
* Open blocks are never visible.
* Sealed blocks are immutable.
* Sealed blocks are sharded by prefix for filesystem scalability.
---
## 5. Index Segments
```
index/
shard-000/
segment-0001.idx
segment-0002.idx
bloom.bin
shard-001/
...
```
Rules:
* Segments are append-only while open.
* Sealed segments are immutable and log-visible.
* Shards are deterministic per snapshot.
---
## 6. Log and Snapshots
```
log/
asl.log
snapshots/
<snapshot-id>/
```
Rules:
* Log is append-only.
* Snapshots pin index and block state for replay.
---
## 7. Temporary and Metadata Paths
* `tmp/` is for transient files only.
* `meta/` contains domain metadata (DAM, policy, host state).
---
## 8. Non-Goals
ASL/STORE-LAYOUT/1 does not define:
* Device selection or mount options
* Snapshot mechanism (ZFS vs other)
* Encryption or key management

# ASL/SYSTEMRESCUE-OVERLAY/1 - Intake Overlay Layout
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, rescue, overlay]
**Document ID:** `ASL/SYSTEMRESCUE-OVERLAY/1`
**Layer:** O3 - Rescue overlay profile
**Depends on (normative):**
* `ASL/HOST/1`
**Informative references:**
* `ASL/RESCUE-NODE/1`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be
interpreted as in RFC 2119.
---
## 1. Purpose and Scope
This overlay defines what exists at boot for a rescue intake environment. It
separates immutable tools from mutable runtime state and defines mount points
for local or remote ASL stores.
---
## 2. Overlay Layout
```
overlay/
├── usr/
│ └── local/
│ ├── bin/
│ │ ├── asl-intake
│ │ ├── asl-admin
│ │ └── asl-debug
│ └── lib/

└── mnt/
└── asl/
├── local/
└── remote/
```
---
## 3. Directory Semantics
* `/usr/local/bin` is immutable and MUST NOT be written at runtime.
* `/etc/asl` contains declarative configuration only.
* `/var/lib/asl` contains all mutable state for the rescue session.
* `/mnt/asl/local` is the mount target for a local ASL store.
* `/mnt/asl/remote` is an optional remote mount.
---
## 4. Local Store Layout (Informative)
When mounted, a local store typically exposes:
```
/mnt/asl/local/
├── blocks/
├── segments/
├── snapshots/
└── logs/
```
This internal layout is backend-defined and not mandated by this overlay.
---
## 5. Services
### 5.1 asl-preflight.service
Responsibilities:
* Detect storage backends
* Detect importable pools
* Write mode decisions to `/run/asl/mode`
### 5.2 asl-intake.service
Responsibilities:
* Read `/run/asl/mode`
* Start `asl-intake` with the selected backend
---
## 6. Configuration Defaults
`/etc/asl/asl.conf` SHOULD include at minimum:
```
mode = auto
local.mount = /mnt/asl/local
remote.endpoint = none
```
---
## 7. Versioning
Backward-incompatible overlay changes MUST bump the major version.

---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be interpreted as in RFC 2119.
ASL/USB-EXCHANGE/1 defines a filesystem layout for offline request/response exchanges via removable media. It does not define PEL or PER encodings.
---
## 1. Purpose
This document defines the on-media layout for USB-based request/response exchanges used in offline rescue, admission, and authority operations.
---
## 2. Request Layout (Normative)
```
/usb/REQUEST/
├── manifest.yaml # REQUIRED
├── pel-program.yaml # REQUIRED
├── input-artifacts/ # OPTIONAL
├── policy.hash # REQUIRED
├── request.sig # REQUIRED
└── meta/ # OPTIONAL
├── requester-domain.txt
└── notes.txt
```
### 2.1 `manifest.yaml` (Normative)

- receipt
- dam # optional
policy_hash: <sha256>
pel_program_hash: <sha256>
input_artifact_hashes:
- <sha256>
signing:
algorithm: ed25519
signer_hint: <string>
```
Invariants:
* `manifest.yaml` is canonical; all hashes are computed over canonical encodings.
* `policy.hash` MUST match `manifest.yaml.policy_hash`.
* `request.sig` MUST cover the canonical manifest.
---
## 3. Response Layout (Normative)
```
/usb/RESPONSE/

│ └── domain.dam
├── response.sig # REQUIRED
└── meta.yaml # OPTIONAL
```
Invariants:
* RESPONSE is append-only; existing entries MUST NOT be modified.
* `response.sig` MUST cover the canonical receipt and published artifacts manifest.
---
## 4. Exchange Rules (Normative)
1. A RESPONSE MUST correspond to exactly one REQUEST.
2. `receipt.per` MUST be verifiable under `PER/SIGNATURE/1`.
3. Published artifacts MUST be a subset of the requested outputs.
4. If a DAM is included, it MUST match the request type and policy hash.
---
## 5. Non-Goals
ASL/USB-EXCHANGE/1 does not define:
* PEL operator constraints or execution semantics
* PER payload encodings
* Transport beyond filesystem layout

## 3. Domains
Domain layout MUST follow ENC-ASL-HOST/1 under:
```
/asl-auth-host/domains/<domain-id>/
```
---
## 4. Environment Claims
```
/asl-auth-host/env-claims/
```
Each claim MUST be stored as an immutable artifact, named by snapshot or
content hash.

```
/asl-auth-host/sops-bundles/
```
Bundles contain DAMs, receipts, and policy artifacts for offline transfer.
---
## 6. Tools
```
/asl-auth-host/tools/
```
Authority binaries and scripts SHOULD be versioned and treated as immutable.
---

### 7.1 Store Blocks
```
<block-id>.bin
<block-id>.meta
```
### 7.2 Index Segments
```
segment-<n>.idx
bloom-<n>.bf
```

```
log-<seq>.aol
```
### 7.4 Snapshots
```
snapshot-<id>.meta
snapshot-<id>.blocks
```

```
policy-<hash>.json
```
### 7.7 DAM Artifacts
```
dam-<seq>.json.sig
```
### 7.8 Environment Claims
```
<snapshot-id>.claim
```
Environment claims SHOULD include:
* OS image hash

# ENC-ASL-HOST/1 - On-Disk Layout for ASL/HOST
Status: Draft
Owner: Architecture
Version: 0.1.0
SoT: No
Last Updated: 2026-01-17
Tags: [ops, host, layout]
**Document ID:** `ENC-ASL-HOST/1`
**Layer:** O1E - Host layout profile (storage-agnostic)
**Depends on (normative):**
* `ASL/HOST/1`
* `ASL/1-STORE`
* `ASL/LOG/1`
**Informative references:**
* `ASL/DAM/1`
* `ASL/DAP/1`
* `ENC-ASL-LOG`
* `ENC-ASL-CORE-INDEX`
---
## 0. Conventions
The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, and **MAY** are to be
interpreted as in RFC 2119.
This document defines directory and file placement only. It does not define
byte-level encodings or storage engine internals.
---
## 1. Purpose and Scope
ENC-ASL-HOST/1 specifies a minimal, storage-agnostic on-disk layout for
ASL/HOST implementations. It standardizes where host metadata, domain data,
logs, and snapshots live.
---
## 2. Root Layout
```
/asl-host/
├── host/
├── domains/
├── federation/
└── quarantine/
```
All host-managed state MUST live under `/asl-host`.
---
## 3. Host-Level Metadata
```
/asl-host/host/
├── host-id
├── host-policy
└── trusted-roots/
```
* `host-id` is a stable identifier for the host.
* `host-policy` contains local policy constraints.
* `trusted-roots/` contains offline trust anchors.
---
## 4. Domain Root
Each domain has a single root directory:
```
/asl-host/domains/<domain-id>/
```
Nothing outside this directory MAY be interpreted as part of the domain state.
---
## 5. Domain Descriptor
```
/asl-host/domains/<domain-id>/domain.json
```
The descriptor contains host-derived metadata (not signed):
```
{
"domain_id": "...",
"state": "COURTESY|FULL|SUSPENDED|REVOKED",
"created_at": "...",
"admitted_at": "...",
"root_key_fingerprint": "...",
"policy_hash": "...",
"current_snapshot": "...",
"current_logseq": 0
}
```
---
## 6. Admission Records
```
/asl-host/domains/<domain-id>/admission/
├── dam.cbor
├── dam.sig
├── admission-request.cbor
├── admission-decision.cbor
└── admission-decision.sig
```
Admission records are immutable and MUST be retained.
---
## 7. Authority Material
```
/asl-host/domains/<domain-id>/auth/
├── root.pub
├── operators/
├── device.pub
└── revocations/
```
Private keys MAY exist only temporarily and SHOULD NOT be required for
steady-state operation.
---
## 8. Store Area
```
/asl-host/domains/<domain-id>/store/
├── blocks/
│ ├── open/
│ ├── sealed/
│ └── gc/
├── objects/
└── encryption/
```
* `open/` blocks are writable and may be lost on crash.
* `sealed/` blocks are immutable.
* `gc/` is host-managed reclaim staging.
---
## 9. Index Area
```
/asl-host/domains/<domain-id>/index/
├── segments/
├── bloom/
└── tmp/
```
Segment encodings are defined by `ENC-ASL-CORE-INDEX`.
---
## 10. Log Area
```
/asl-host/domains/<domain-id>/log/
```
Log records and envelopes are defined by `ENC-ASL-LOG`.
---
## 11. Snapshot Area
```
/asl-host/domains/<domain-id>/snapshots/
```
Snapshot metadata MUST include the log sequence boundary and segment set used
for deterministic replay.
---
## 12. Leases
```
/asl-host/domains/<domain-id>/leases/
```
Courtesy lease metadata is stored here and MUST NOT be interpreted by
ASL/1-STORE.
---
## 13. Temporary Workspace
```
/asl-host/domains/<domain-id>/tmp/
```
The host MAY use this directory for temporary, non-authoritative files.
It MUST NOT be required for deterministic replay.
---
## 14. Federation (Optional)
```
/asl-host/federation/
├── peers/
├── exports/
└── imports/
```
Federation caches are optional and MUST NOT change local domain state.
---
## 15. Quarantine
```
/asl-host/quarantine/
```
Untrusted or failed admissions MAY be staged here for inspection.
---
## 16. Versioning
Backward-incompatible layout changes MUST bump the major version.

# amduat-api registry (draft)
This directory mirrors the core `vendor/amduat/registry/` model for the
**amduatd HTTP API contract**.
## Goal
- Keep a stable, machine-readable API contract in-repo.
- Seed that contract into the daemon's single ASL store root at startup.
- Advertise the store-backed contract `ref` via `GET /v1/meta`.
The daemon remains thin: the contract bytes are data, and the store-backed `ref`
acts as the version identifier.
## Files
- `api-contract.schema.md` — JSONL manifest schema for API contracts.
- `api-contract.jsonl` — manifest of published contracts.
- `amduatd-api-contract.v1.json` — contract bytes (v1).
- `amduatd-api-contract.v2.json` — draft contract bytes (v2, PEL-only writes).
Receipt note:
- `/v1/pel/run` accepts optional receipt v1.1 fields (executor fingerprint, run id,
limits, logs, determinism, rng seed, signature) and emits `receipt_ref` when
provided.

# Schema: registry/api-contract.jsonl
Each line is one JSON object (JSONL). This mirrors the conventions described in
`vendor/amduat/registry/README.md`.
## Canonical descriptor digest
`bytes_sha256` is the SHA-256 digest (lowercase hex) of the exact contract bytes
as stored in the corresponding `registry/*.json` file.
## Fields
- `registry` (string, required): registry name, fixed to `AMDUATD/API`.
- `contract` (string, required): contract series identifier (e.g. `AMDUATD/API/1`).
- `handle` (string, required): stable handle (e.g. `amduat.api.amduatd.contract.v1@1`).
- `media_type` (string, required): content type of the bytes (e.g. `application/json`).
- `status` (string, required): `active` | `deprecated` | `reserved`.
- `bytes_sha256` (string, required): sha256 of the bytes file.
- `notes` (string, optional): human notes.
## Contract Notes
- `amduatd-api-contract.v1.json` includes optional receipt v1.1 fields for
`/v1/pel/run` and may emit `receipt_ref` in responses.
- `/v1/fed/records` supports `limit` for paging (default 256, max 10000).

You are an execution planner for a graph-grounded QA agent.
Decide the NEXT action only.
Rules:
- Return STRICT JSON object only.
- action must be one of: "answer", "refine_query", "stop".
- Use "refine_query" only if retrieval context is clearly insufficient.
- Keep next_roots_csv / next_goals_csv empty unless refining.
- Do not include markdown or prose outside JSON.
