audit(0090): cycle + C24 milestone close — fieldtest green; ledger + rm ephemeral spec/plan
Closes the cycle-0090 (#156) work and delivers the "Topology-as-data: blueprint serialization & loader (C24)" milestone. Cycle-0090 audit (architect drift review, range 7ad7f58..HEAD): drift-clean on substance. Tier-1 forward-tolerance is genuinely serde-default (deny_unknown_fields = 0 in every production struct), pinned at envelope + primitive across both the in-crate and public-seam tests; Tier-2 refusals real and green; no struct/signature/runtime change; the invariant-5 acyclicity lockstep (construction gate <-> bootstrap Kahn sort) undisturbed; invariant-9 resolver stays injected, no registry. The one medium item the architect flagged — the C24 Remaining block carried no deferral signal for #158/#159 — is fixed in this commit's ledger update. Milestone fieldtest (fieldtests/milestone-topology-as-data/, the close-gate evidence): GREEN, 0 behavioural bugs. A downstream consumer ran the full author -> serialize -> load -> construct -> introspect -> reproduce story from the public surface alone — round-trip bit-exact on both authoring surfaces (Rust builder + op-script CLI), build-free introspection, Tier-1/Tier-2 forward-compat by name, fail-fast diagnostics by identifier. Verified the headline claims myself (the two Rust binaries + the CLI build/diff + the fail-fast exits), not just the agent's report. Findings triaged to the forward queue (none blocking): op-script grammar undocumented + a stale cycle-0088 example (#163); canonical trailing-newline divergence + Composite Debug/PartialEq ergonomics (#164); CLI discoverability of build/introspect + no `graph run` (commented on #159); the newline as a content-addressing prerequisite (commented on #158). #158 (content-address topology in the manifest) and #159 (retire the hard-wired harnesses) were moved OUT of this milestone: both are premature until the World generates runs from blueprint-data (commit still fully identifies every hard-wired topology), so they belong to the project-as-crate / World cycle. The C24 ledger Status records the delivery and the deferral. Ephemeral cycle-0090 spec + plan removed per the lifecycle convention. The Gitea milestone container is closed on user ratification (this run tees up the close, does not click it).

# Fieldtest — milestone: Topology-as-data (C24) — 2026-06-30
|
||||
|
||||
**Status:** Draft — awaiting orchestrator triage
|
||||
**Author:** fieldtester (dispatched by fieldtest skill)
|
||||
|
||||
## Scope
|
||||
|
||||
The milestone-close gate for **C24 — the blueprint is a serializable,
|
||||
World-owned data value**. The milestone promises a downstream researcher can run
|
||||
the whole topology-as-data story end to end: author a param-generic graph with
|
||||
the Rust builder, **serialize** it to a canonical versioned data value,
|
||||
**load** it back (data → blueprint → runnable), **construct** the same topology
|
||||
declaratively through the CLI op-script (`aura graph build`), **introspect** the
|
||||
closed node vocabulary without a build (`aura graph introspect`), and
|
||||
**reproduce** a run bit-identically (C1). Spanning cycles 0087 (#155 serde
|
||||
first-cut), 0088 (#157 construction service), 0089 (#161/#162 diagnostics +
|
||||
acyclicity), 0090 (#156 forward-compat two-tier).
|
||||
|
||||
Run entirely from the public interface: the C24 ledger entry, `cargo doc`
|
||||
doc-comments, `aura graph introspect`'s own output, and the existing op-script
|
||||
fixture *shape*. No `crates/*/src` was read. Artefact under test:
|
||||
`target/debug/aura` + the engine path-dep crates, both rebuilt from HEAD
|
||||
(`cargo build --workspace`) before the run.
|
||||
|
||||
## Examples
|
||||
|
||||
All fixtures under `fieldtests/milestone-topology-as-data/`.
|
||||
|
||||
### mt_1_roundtrip.rs — Rust round-trip + run identity (tasks 1)
|
||||
- Authors an SMA(2)/SMA(4)-cross bias signal with `GraphBuilder`
|
||||
(`source_role` → `Sma::builder().named().bind()` → `Sub` → `Bias` → `expose`),
|
||||
serializes with `blueprint_to_json`, loads with `blueprint_from_json` +
|
||||
`aura_std::std_vocabulary`, re-serializes, and runs both the original and the
|
||||
reloaded twin through an identical Recorder harness.
|
||||
- Fits scope: the headline C24 acceptance (serialize → load → reproduce).
|
||||
- Outcome: **built, ran, matched.** (a) canonical JSON round-trips
|
||||
byte-identically (647 bytes, serialize→load→re-serialize equal). (b) 9
|
||||
recorded bias rows value-for-value identical between original and reload (C1).
|
||||
|
||||
### mt_2_sma_cross.ops.json + mt_2_blueprint.cli.json — declarative construction + cross-surface identity (task 2)
|
||||
- The same topology as a CLI op-script; `aura graph build < ops.json` emits the
|
||||
#155 blueprint. Compared against `mt_1_rust_blueprint.json` (the library
|
||||
emit).
|
||||
- Fits scope: C1 identity across authoring surfaces (Rust builder vs op-script).
|
||||
- Outcome: **built, ran, matched (modulo one byte).** The two blueprints are
|
||||
**character-for-character identical** except the CLI appends a trailing `\n`
|
||||
(648 vs 647 bytes). See spec_gap below.
|
||||
|
||||
### mt_3_*.out + mt_3_partial.ops.json — build-free introspection (task 3)
|
||||
- `introspect --vocabulary` (22 closed types), `--node SMA|Sub|Bias|EMA|RollingMax`
|
||||
(ports, kinds, bind form), and `--unwired` on a partial op-list.
|
||||
- Fits scope: discover the vocabulary / a node's ports / unwired slots without a
|
||||
build.
|
||||
- Outcome: **ran, matched.** `--unwired` on a partial doc reports `sub.rhs:F64`
|
||||
(the one open slot, by identifier, no build). `--node LinComb`/`Recorder`
|
||||
correctly refuse (`unknown node type`, exit 2) — they are outside the
|
||||
round-trippable set, as the ledger states.
|
||||
|
||||
### mt_4_forward_compat.rs — forward-compat Tier-1/Tier-2 + cross-surface interop (tasks 4)
|
||||
- Loads the **CLI-emitted** blueprint via the **library** loader (cross-surface
|
||||
interop); injects unknown optional fields at envelope and node level (Tier-1);
|
||||
bumps `format_version` to 999 and swaps a node type to `FOO` (Tier-2).
|
||||
- Fits scope: the #156 two-tier discipline from the loader's seat.
|
||||
- Outcome: **built, ran, matched.** CLI blueprint loaded + ran identically
|
||||
(trailing newline tolerated). Tier-1 unknown fields tolerated, dropped on
|
||||
re-emit (back to canonical), ran bit-identical. Tier-2 refused **by name** —
|
||||
`UnsupportedVersion { found: 999, supported: 1 }` and `UnknownNodeType("FOO")`
|
||||
— no panic, no silent wrong graph.
|
||||
|
||||
### mt_5{a,b,c}_*.ops.json + .err/.exit — fail-fast CLI diagnostics (task 5)
|
||||
- Three malformed op-lists fed to `aura graph build`: unknown node type, a
|
||||
connect that closes a cycle, an unconnected input slot.
|
||||
- Fits scope: invalid construction must fail fast, by identifier, non-zero exit.
|
||||
- Outcome: **ran, matched.** Each reported by identifier with empty stdout and
|
||||
exit 2 (verbatim below).
|
||||
|
||||
## Findings
|
||||
|
||||
### [working] The C24 round-trip is real and bit-exact, both surfaces
|
||||
- Examples: mt_1, mt_2, mt_4.
|
||||
- What happened: a builder-authored signal serialized → loaded → re-serialized
|
||||
byte-identically (647 bytes) and the reload ran value-for-value identical to
|
||||
its twin (9 bias rows). The CLI op-script emitted a blueprint whose **content
|
||||
is character-identical** to the library emit, and that CLI blueprint loaded
|
||||
through the library loader and ran identically.
|
||||
- Why working: the milestone's central promise (author → serialize → load →
|
||||
reproduce, identical across the Rust and CLI authoring surfaces) holds on
|
||||
first try from the public surface alone.
|
||||
- Recommended action: carry-on. These are the C24 acceptance pins, empirically
|
||||
confirmed downstream.
|
||||
|
||||
### [working] Build-free introspection answers the three discovery questions
|
||||
- Examples: mt_3.
|
||||
- What happened: `--vocabulary` listed the closed 22-type set; `--node`
|
||||
surfaced ports/kinds **and** the exact bind form (`param length:I64 (bind
|
||||
{"I64": <v>})`); `--unwired` named the single open slot `sub.rhs:F64` with no
|
||||
build. Out-of-vocabulary `--node LinComb`/`Recorder` refused cleanly (exit 2).
|
||||
- Why working: a consumer can discover the entire authorable surface (what nodes
|
||||
exist, each node's ports, what a partial doc still needs) without compiling
|
||||
anything — exactly the #157 introspection promise.
|
||||
- Recommended action: carry-on.
|
||||
|
||||
### [working] Forward-compat + fail-fast diagnostics are by-name / by-identifier
|
||||
- Examples: mt_4, mt_5.
|
||||
- What happened: Tier-1 unknown fields tolerated and dropped on re-emit; Tier-2
|
||||
refused by name with values (`found: 999, supported: 1`; `"FOO"`). The three
|
||||
build failures each named the cause at the offending site:
|
||||
`op 1 (add): unknown node type "FOO"`;
|
||||
`op 5 (connect): connecting b.value -> a.rhs would close a cycle`;
|
||||
`finalize: slot sub.rhs is unconnected` — all exit 2, all with empty stdout
|
||||
(no half-emitted blueprint).
|
||||
- Why working: every refusal is actionable and points at an identifier, never a
|
||||
raw index or a panic — the #161/#162 polish landed and holds downstream.
|
||||
- Recommended action: carry-on.
|
||||
|
||||
### [friction] The construction surface is undiscoverable from the CLI's own help
|
||||
- Examples: observed probing `aura --help`, `aura graph --help`, `aura graph`.
|
||||
- What happened: top-level usage lists only `aura graph` (no `build` /
|
||||
`introspect`). `aura graph --help` reprints the same top-level usage. `aura
|
||||
graph` with no subcommand silently streams a ~1.4 MB HTML viewer to stdout and
|
||||
exits 0. The only way I learned `build`/`introspect` existed was the C24
|
||||
ledger; the only way I learned the introspect flags was triggering its usage
|
||||
line by passing a bad arg.
|
||||
- Why friction: the task completed, but a consumer with only the binary cannot
|
||||
find the milestone's headline CLI surface. (Known/filed as #159.)
|
||||
- Recommended action: plan — add a `graph` subcommand help listing
|
||||
`build | introspect` and their flags; make bare `aura graph` print usage
|
||||
rather than dump HTML to a TTY.
|
||||
|
||||
### [friction] The op-script JSON schema is documented nowhere durable; the only example is stale
|
||||
- Examples: mt_2 (and the failed build of `fieldtests/cycle-0088-…/c0088_1`).
|
||||
- What happened: no durable public doc (ledger, glossary, README) states the
|
||||
op-list grammar — the verbs (`source`/`add`/`feed`/`connect`/`expose`) or
|
||||
their keys. `aura graph build --help` does not exist (empty input just prints a
|
||||
JSON parse error). The only worked example is the cycle-0088 fixture corpus,
|
||||
which still uses the **retired `as` key** for `add`; replaying it verbatim
|
||||
fails with `op 2 (add): duplicate identifier "sma"` because `add`'s naming key
|
||||
was renamed `as → name` (commit `feat: construction add names a node via name`).
|
||||
A consumer copying the visible example hits this immediately.
|
||||
- Why friction: I had to reconstruct the correct schema (`"name"` not `"as"` for
|
||||
`add`; `"as"` retained only for `expose`) by cross-reading the commit log — a
|
||||
downstream consumer reading docs + the example corpus would be misled.
|
||||
- Recommended action: plan / docwriter — document the op-script grammar in a
|
||||
durable doc (or `aura graph build --help`), and either refresh or clearly
|
||||
date-stamp the cycle-0088 corpus as pre-rename.
|
||||
|
||||
### [friction] Closing the loop to a *run* drops out of the data surface into hand-wired Rust
|
||||
- Examples: mt_1, mt_4 (the Recorder wrapper).
|
||||
- What happened: the serializable unit is the sink-less signal composite (a
|
||||
Recorder captures an `mpsc::Sender`, deliberately outside the round-trippable
|
||||
set). To *observe* a reloaded blueprint actually running, I had to drop to
|
||||
Rust, hand-author a wrapper `Composite` by raw index, attach a `Recorder`, and
|
||||
bootstrap. There is no `aura graph run <blueprint.json>` (cf. #28): the CLI can
|
||||
author and emit topology but cannot run an emitted blueprint or show its
|
||||
trace.
|
||||
- Why friction: the milestone's "data → blueprint → **runnable**" is
|
||||
library-complete but, from the CLI alone, dead-ends at the emitted JSON; the
|
||||
reproduce step requires writing Rust and re-introducing a non-serializable
|
||||
sink. (Intended per the ledger, but a real seam a consumer feels.)
|
||||
- Recommended action: plan — track under the #28/#159 build→consume edge (a CLI
|
||||
consumer that loads a blueprint, attaches a sink/tap, and runs).
|
||||
|
||||
### [spec_gap] "Canonical" form: CLI `graph build` appends a trailing newline the library emit omits
|
||||
- Examples: mt_2 (`mt_2_blueprint.cli.json` 648 B vs `mt_1_rust_blueprint.json`
|
||||
647 B; last bytes `5d 7d 7d 0a` vs `7d 5d 7d 7d`).
|
||||
- What happened: both paths emit the documented "canonical, versioned" blueprint,
|
||||
byte-identical in content, but the CLI frames it with a trailing `\n` and the
|
||||
library `blueprint_to_json` does not. The ledger calls the format canonical and
|
||||
lists **content-addressed topology identity in the manifest (#158)** as
|
||||
remaining — yet a content hash of the same blueprint differs by which surface
|
||||
emitted it.
|
||||
- Why spec_gap: the ledger does not constrain whether the canonical artifact
|
||||
includes a trailing newline; I picked the reading "the JSON content is
|
||||
canonical, the CLI's newline is incidental framing," but the reading "the CLI's
|
||||
stdout *is* the canonical on-disk artifact" is equally plausible, and the two
|
||||
disagree by one byte — load-bearing once #158 content-addresses topology.
|
||||
- Repro: `diff <(aura graph build < mt_2_sma_cross.ops.json)
|
||||
mt_1_rust_blueprint.json` → differs only by the final newline.
|
||||
- Recommended action: ratify / tighten the ledger — state whether canonical
|
||||
includes a trailing newline and make the two emit paths byte-identical before
|
||||
#158 lands.
|
||||
|
||||
### [spec_gap] `Composite` (the loaded value) has no `Debug` / `PartialEq`
|
||||
- Examples: mt_4 (a `match` had to avoid `{:?}`-ing the `Ok(Composite)` arm; a
|
||||
direct `assert_eq!` on two loaded composites is impossible).
|
||||
- What happened: `blueprint_from_json` returns `Result<Composite, LoadError>`,
|
||||
but `Composite` derives neither `Debug` nor `PartialEq`, so `unwrap_err()`,
|
||||
`{:?}`, and composite-level equality assertions don't compile. A consumer must
|
||||
route every identity/round-trip assertion through `blueprint_to_json` (string
|
||||
compare), which is what I did.
|
||||
- Why spec_gap: the ledger frames the blueprint as a first-class data **value**
|
||||
the World "owns, stores, mutates, structurally searches" — value-like
|
||||
ergonomics (compare, debug-print) are implied but unspecified, and the type as
|
||||
shipped supports neither.
|
||||
- Recommended action: ratify / tighten — decide whether the public `Composite`
|
||||
value should carry `Debug`/`PartialEq` (string-via-JSON is the current
|
||||
contract); document the intended equality surface.
|
||||
