BREAKING CHANGE: The `warp-ffi` crate has been deleted. C ABI is abandoned because C's undefined behavior is incompatible with Echo's determinism guarantees. Rust plugin extension via RewriteRule trait registration and Rhai scripting replace this path. Changes: - Delete `crates/warp-ffi/` (C ABI surface for warp-core) - Remove warp-ffi from workspace Cargo.toml - Remove warp-ffi rustdoc gate from CI - Clean all warp-ffi references from docs (code-map, spec-warp-core, rust-rhai-ts-division, phase1-plan, warp-demo-roadmap, project-tour) - Fix pre-existing MD024 duplicate heading lint in rust-rhai-ts-division.md TASKS-DAG updates: - #26 Plugin ABI (C) v0 → Closed (Graveyard) - #86 C header + host loader → Closed (Graveyard) - #87 Version negotiation → Closed (Graveyard) - #88 Capability tokens → Closed (Graveyard) - #89 Example plugin + tests → Closed (Graveyard) - #38 FFI limits and validation → Closed (Graveyard) - #39 WASM input validation → Completed (was stale "In Progress") - #202 Provenance Payload → Open + full Paper III task breakdown (PP-1 through PP-6) - #231 Tumble Tower Stage 0 → Open (was stale "In Progress") Closes #26, #86, #87, #88, #89, #38
Developer CLI (P0): - Full clap 4 derive CLI with verify, bench, inspect subcommands - WSC loader bridging columnar format to GraphStore reconstruction - verify: validates WSC snapshots, recomputes state root hashes - bench: parses Criterion JSON, renders ASCII tables via comfy-table - inspect: metadata display, graph stats, --tree ASCII visualization - Global --format text|json flag for machine-readable output - Man page generation via clap_mangen in xtask Provenance Payload Spec (PP-1): - SPEC-0005 maps Paper III formalism to concrete Echo types - Defines ProvenancePayload, BoundaryTransitionRecord, ProvenanceNode, DerivationGraph - Wire format with CBOR encoding and domain separation tags - Two worked examples and attestation envelope with SLSA alignment

There was a problem hiding this comment.
This config sends the child cargo bench stdout/stderr directly to the terminal, so echo-cli --format json bench will emit cargo/Criterion text before the JSON payload and break machine parsing in CI. The comment says output is being suppressed, but Stdio::inherit() does the opposite, so JSON mode is not reliably consumable.

There was a problem hiding this comment.
The --filter option is documented as a pattern match, but this passes it to Cargo's --bench target selector. I checked cargo bench --help: positional [BENCHNAME] is what "run benches containing this string in their names", while --bench [<NAME>] means "Benchmark only the specified bench target". With the current code, common filters like hotpath fail unless they exactly match a bench target name.

There was a problem hiding this comment.
The collector only checks <entry>/new/estimates.json one level under target/criterion, so it skips grouped/parameterized Criterion outputs that live in deeper paths. In this repo, several benches use benchmark_group/parameterized IDs, which produce nested directories, so successful runs can be underreported or shown as "no results found".

Inline comments:
In `@Cargo.toml`:
- Around line 5-7: The workspace removal of the crate "warp-ffi" requires
purging all remaining references: search for and remove or update any
occurrences of "warp-ffi" in det-policy.yaml (the crate class entry) and in
documentation files that mention warp-ffi, replacing with the correct crate
names ("crates/warp-core", "crates/warp-wasm") or deleting obsolete guidance;
ensure det-policy.yaml no longer points to a non-existent crate class and update
docs to reflect current workspace crates so no dead policy paths or stale
instructions remain.
In `@CHANGELOG.md`:
- Around line 8-40: The changelog is missing a Breaking/Removed entry for the
refactor that removes the C ABI path (`warp-ffi`) — add a "Removed" or "Breaking
Changes" subsection under the "Unreleased" heading that states the removal of
`warp-ffi`/C ABI, marks the release as containing a breaking change (refactor!),
and provides concise migration guidance pointing users to the new Rust-based CLI
path (`echo-cli` subcommands such as `verify`, `inspect`, `bench`) and any
necessary data-flow differences (e.g., use `echo-cli verify <snapshot.wsc>`
instead of the C ABI). Ensure the entry references `warp-ffi` and `echo-cli`
clearly so users can find the new migration steps.
In `@crates/warp-cli/README.md`:
- Around line 33-36: The README entry for the command `echo-cli bench [--filter
<pattern>]` is misleading: it currently says the command "Run Criterion
benchmarks" but the implementation parses existing Criterion JSON results;
update the wording to state that the command parses Criterion JSON benchmark
results (optionally filtered by <pattern>) and formats them as an ASCII table,
replacing the current phrasing so it no longer implies the command executes
benchmarks.
In `@crates/warp-cli/src/bench.rs`:
- Around line 86-138: collect_criterion_results currently does a non-recursive
scan which misses grouped benchmarks, silently drops parse failures, and assumes
a hardcoded "target/criterion" path; fix it by (1) making the scan recursive to
find patterns like group_name/benchmark_name/new/estimates.json (e.g. use
WalkDir or nested read_dir up to depth 3 and match directories whose path ends
with "new/estimates.json"), (2) replace the silent ignore around
parse_estimates(&bench_name, &estimates_path) with error handling that
logs/warns the file path and parse error (use the project logger or
eprintln!/tracing::warn! so corrupted JSON is reported), and (3) stop relying on
a literal Path::new("target/criterion") and instead resolve the Cargo target
directory (e.g. accept a resolved criterion_dir argument from caller or compute
it via cargo metadata / target_directory) so collect_criterion_results works
when run from sub-crates; update the function references
collect_criterion_results, parse_estimates, and the estimates_path construction
accordingly.
- Around line 42-84: The run function currently inherits child stdout/stderr
which allows cargo/criterion to write raw output into the parent stdout and
contaminate the JSON that emit() prints; change the Command invocation in run
(where cmd is built and stdout/stderr are set) to capture the child output
instead of inheriting it so you can suppress or read it (e.g., use Stdio::null
or .output() and discard/inspect stdout/stderr) before calling emit(); also fix
the filter wiring: when a filter is provided, keep using cmd.args(["--bench",
f]) to select the bench target (as seen in run) but pass the Criterion benchmark
regex after the cargo “--” separator (i.e., add cmd.arg("--").arg(filter) or
equivalent) so Criterion receives the pattern, and ensure
collect_criterion_results still receives the same filter when parsing results.
In `@crates/warp-cli/src/inspect.rs`:
- Around line 140-190: The current count_connected_components function builds a
heavyweight BTreeMap<[u8;32], BTreeSet<[u8;32]> > adjacency which causes many
allocations; replace it with an index-based adjacency using a Vec<Vec<usize>>:
first build a mapping from node_id -> index (using BTreeMap or Vec of sorted ids
to keep determinism) from view.nodes(), allocate adjacency:
Vec::with_capacity(nodes.len()) and push empty Vecs, then iterate view.edges()
and push neighbor indices into adjacency by looking up from_node_id and
to_node_id via the mapping, and perform BFS using usize indices instead of
[u8;32] values; alternatively, if you prefer a behavior change instead of
refactor, make the connected-components calculation behind an optional flag
(e.g., --components) so count_connected_components is only invoked when
requested (adjust the inspect command handling accordingly).
- Around line 214-257: build_tree_node currently builds a spanning tree using
the shared visited set (so multiply-reachable nodes are silently omitted) and
only checks bounds for edge_ix; update the function to (1) document
spanning-tree semantics in the CLI help text (explain that nodes may be omitted
because of depth limits or because the tree suppresses already-visited nodes),
(2) harden edge validation by verifying that the out_edge index actually refers
to the same edge object in view.edges() (e.g., compare
out_edge.edge_ix()/out_edge.edge_id() with view.edges()[edge_ix].edge_id or
another stable identifier, and log/return/skip with an error if they differ to
detect corruption), and (3) when a child is skipped due to
visited.contains(to_id) add a placeholder child entry such as "(...already
visited...)" (or similar) in children so the printed tree reflects suppressed
edges; all changes should be applied inside build_tree_node and the CLI help
text area that constructs/prints the tree.
In `@crates/warp-cli/src/main.rs`:
- Around line 28-38: The match currently moves cli.command which prevents later
borrows of cli.format; change the match to borrow the command (e.g., match
&cli.command or bind let cmd = &cli.command) so you pass references into
verify::run, bench::run and inspect::run while still using &cli.format; ensure
you use as_deref()/as_deref_mut() on the borrowed option values as before and
keep calls to verify::run, bench::run and inspect::run unchanged except for
taking references to the command's contents.
In `@crates/warp-cli/src/verify.rs`:
- Around line 224-238: The test tampered_wsc_fails is currently ineffective
because it only drops the result; update it to deterministically detect
tampering by first computing the original state root hex from make_test_wsc (use
whatever accessor returns the state root), then tamper bytes in a region that
affects the state root (instead of random middle flip), write the file via
write_temp_wsc, call run with the expected parameter set to the original_hex
(i.e., run(f.path(), Some(original_hex), &OutputFormat::Text)), and assert that
run returns an Err / non-zero failure (or contains the mismatch error) rather
than silently passing; reference the test function tampered_wsc_fails, helper
make_test_wsc, write_temp_wsc, and run to locate where to change the assertion.
- Around line 42-118: The report currently embeds human text in
WarpVerifyResult.status and only applies the --expected string to warp 0; change
the report shape and how expected is recorded: update the WarpVerifyResult
struct to replace the freeform status String with a structured set of fields
(e.g. status: "pass" | "mismatch", expected: Option<String>, actual: String),
and update run(...) to populate these fields (set expected to
Some(exp.to_string()) only for the warp the CLI intends — currently warp 0 — and
set status to "pass" or "mismatch" accordingly, removing the "MISMATCH (...)"
message; also update VerifyReport.result derivation and the JSON emission
(serde) to use the new fields so the JSON is machine-friendly.
In `@crates/warp-cli/src/wsc_loader.rs`:
- Around line 147-195: The roundtrip tests only cover node Atom attachments; add
test coverage that also sets an edge attachment and a Descend-style attachment
so hashing includes edge/tag-dependent data: update or add a test (e.g., extend
roundtrip_with_attachments or add roundtrip_with_edge_and_descend_attachments)
to call GraphStore::set_edge_attachment(...) and
GraphStore::set_node_attachment(...) using AttachmentValue::Descend(...) as well
as an Atom attachment, then build the WSC input via build_one_warp_input, write
it with write_wsc_one_warp, reload with WscFile::from_bytes and warp_view,
reconstruct via graph_store_from_warp_view, and assert the
reconstructed.canonical_state_hash() equals the original.canonical_state_hash();
reference the functions/types NodeId/NodeRecord/AttachmentValue::Descend,
set_edge_attachment, set_node_attachment, build_one_warp_input,
write_wsc_one_warp, WscFile, warp_view, graph_store_from_warp_view, and
canonical_state_hash when locating where to add the assertions.
- Around line 23-62: graph_store_from_warp_view silently ignores extra
attachments by using atts.first() without checking atts.len() <= 1; change the
loader to enforce the "at most one attachment" invariant by making
graph_store_from_warp_view fallible (e.g., return Result<GraphStore,
LoaderError>) and validate the attachment slices returned by
view.node_attachments(node_ix) and view.edge_attachments(edge_ix): if atts.len()
> 1 return a descriptive error (or explicitly assert during a quick fix) instead
of truncating, and propagate the new Result to callers so a malformed WSC
produces a clear error rather than an incorrect canonical_state_hash.
- Around line 84-94: In att_row_to_value, don’t silently treat missing blobs as
empty and don’t treat any non-atom tag as Descend; call
view.blob_for_attachment(att) and replace unwrap_or(&[]) with a fail-fast call
(e.g., expect/unwrap with a descriptive message) so missing blobs panic instead
of producing empty Atom payloads, and replace the loose else branch with an
explicit check using att.is_descend() to decide between
AttachmentValue::Descend(WarpId(...)) and panicking on unknown tags; refer to
att_row_to_value, AttRow::is_atom, AttRow::is_descend, and
view.blob_for_attachment to locate changes.
In `@crates/warp-cli/tests/cli_integration.rs`:
- Around line 75-82: The test format_flag_is_global currently only checks the
before-subcommand case; update it to also assert the after-subcommand case by
invoking echo_cli() with the args ordering where the global flag appears after
the subcommand (e.g., call echo_cli().args(["verify", "--format", "json",
"--help"]).assert().success()); modify the test function format_flag_is_global
to include both assertions (the existing ["--format","json","verify","--help"]
case and the new ["verify","--format","json","--help"] case) using the same
echo_cli() helper so the integration test validates both flag orderings.
- Around line 8-15: Remove the blanket #![allow(deprecated)] and stop using the
deprecated cargo_bin trait method; replace the use of cargo_bin in the
echo_cli() helper with the non-deprecated macro
assert_cmd::cargo::cargo_bin_cmd! to produce the command. Concretely, delete the
file-level allow, import or reference the cargo_bin_cmd! macro from
assert_cmd::cargo, and change the echo_cli() function (which currently calls
Command::new(cargo_bin("echo-cli"))) to construct the command via the
cargo_bin_cmd! macro so deprecation warnings are avoided.
In `@docs/man/echo-cli-verify.1`:
- Around line 7-13: The synopsis line for the verify command is inconsistent:
change the invocation from showing `--expected` flag-only to include its
required value (e.g., `--expected <EXPECTED>` or `--expected=<EXPECTED>`) so it
matches the option block; update the `verify` synopsis to present `--expected`
with the `<EXPECTED>` placeholder and ensure the same formatting tokens (e.g.,
\fB\-\-expected\fR \fI<EXPECTED>\fR) are used as in the OPTIONS section to keep
shell completion and docs consistent.
In `@docs/notes/project-tour-2025-12-28.md`:
- Around line 99-101: Update the docs/notes entry that calls `crates/warp-cli` a
"Placeholder CLI home" to describe the implemented CLI surface: replace the
placeholder text with a short list of the implemented commands (`verify`,
`bench`, `inspect`) and a brief note of their purposes (e.g., `verify` for
validation, `bench` for benchmarking, `inspect` for introspection), and remove
any language implying the crate is incomplete so the section accurately reflects
the current `crates/warp-cli` functionality.
In `@docs/phase1-plan.md`:
- Around line 63-67: Update the roadmap to remove the obsolete "Expose C ABI for
host integrations" task and any mention of "warp-ffi" so it no longer suggests
pursuing the C ABI direction; replace that bullet with a compliant alternative
(e.g., "Document host integration patterns for Rust/WASM or add WASM host
bindings") and ensure the demonstration line remains consistent with
snapshot-based flows (reference the exact bullet text "Expose C ABI for host
integrations" and the dependency name "warp-ffi" when making the edit).
In `@docs/rust-rhai-ts-division.md`:
- Around line 22-29: Update the docs to replace references to the old CLI names
and commands: remove or replace mentions of `warp` and `warp-cli` and document
the new `echo-cli` interface and its subcommands (`verify`, `bench`, `inspect`);
specifically edit the section that currently lists "CLI tools: `warp` command
for apply/snapshot/diff/verify" and the "Key Crates" entries (`warp-core`,
`warp-wasm`, `warp-cli`) so they reference `echo-cli` and the correct command
set, and ensure any examples or command usage reflect `echo-cli
verify|bench|inspect` rather than `warp`/`warp-cli`.
In `@docs/spec/SPEC-0005-provenance-payload.md`:
- Around line 104-106: The invariant using patches[i].header.global_tick == i is
incorrect because global_tick is an absolute timeline coordinate and not
zero-based per payload; change the specification to require that
patches[*].header.global_tick is strictly increasing and contiguous across the
slice (e.g., patches[i+1].header.global_tick == patches[i].header.global_tick +
1) rather than equating global_tick to the vector index, and clarify in the text
that continuity is enforced over the selected range (worldline slice/fork)
rather than resetting to zero at each payload.
- Around line 201-203: The recomputation step references `parents` which
`BoundaryTransitionRecord` (BTR) does not include, making `recompute commit_hash
from (h_out, parents, patch_digest, policy_id)` unimplementable; either (A) add
a deterministic `parents` field to the BTR schema and include it in the BTR
structure and examples (so `btr.parents` is available for recomputation), or (B)
remove `parents` from the recomputation recipe and update the formula to compute
`commit_hash` only from the actual BTR fields (`h_out`, `patch_digest`,
`policy_id`, etc.); update all references to `commit_hash` computation and the
SPEC text so the formula matches the BTR structure (reference symbols:
BoundaryTransitionRecord, btr, commit_hash, h_out, patch_digest, policy_id,
parents).
- Around line 352-357: The table in SPEC-0005 lists incorrect domain-tag byte
lengths for two entries; update the `ProvenancePayload` digest row to use
`echo:provenance_payload:v1\0` with a byte length of 27 (not 28) and update the
`ProvenanceEdge` identifier row to use `echo:provenance_edge:v1\0` with a byte
length of 24 (not 25); ensure the `BoundaryTransitionRecord` hash row remains
unchanged and that the normative table text reflects these corrected byte counts
for `ProvenancePayload` and `ProvenanceEdge`.
In `@TASKS-DAG.md`:
- Around line 420-437: Update the acceptance criteria in TASKS-DAG.md so AC1
references the actual spec filename introduced in this PR: change or add the
path from docs/spec/SPEC-PROVENANCE-PAYLOAD.md to
docs/spec/SPEC-0005-provenance-payload.md (or include both paths) so the task
recognizes the delivered file; edit the AC1 entry in the PP-1 block to match
SPEC-0005-provenance-payload.md.
In `@xtask/src/main.rs`:
- Around line 490-492: Before ensuring the output directory exists, add a
pre-pass that removes any existing man pages matching the pattern "echo-cli*.1"
in out_dir (the variable bound from args.out) so the generated docs are an exact
snapshot; implement this by globbing or iterating std::fs::read_dir(out_dir) and
deleting entries whose file_name matches the pattern, propagate or context-wrap
any IO errors similarly to the existing create_dir_all call, then proceed with
the existing create_dir_all call shown in main.rs.
- Around line 503-513: The man pages are rendered from sub.clone() which
preserves the subcommand's bare name (e.g., "bench") but the files and
cross-references expect the canonical "echo-cli-<sub>" name; fix by cloning each
subcommand into a mutable command, set its name to the canonical filename (e.g.,
"echo-cli-{sub_name}") before creating the Man and calling man.render;
specifically update the loop that uses cmd.get_subcommands(), replace
sub.clone() with a cloned-and-renamed command, then call clap_mangen::Man::new
on that renamed clone and proceed to render/write the same filename.

🌐 Web query:
What does cargo bench --bench select, and how do you pass a filter to the Criterion benchmark framework?
💡 Result:
-
cargo bench --bench <name>selects which benchmark target/binary Cargo builds and runs—i.e., the bench target named<name>(typically a file likebenches/<name>.rs, or a[[bench]]target inCargo.toml). It does not select individual Criterion benchmark functions/groups inside that binary. [1] -
To filter which Criterion benchmarks run inside that selected bench binary, pass a filter after
--(it’s treated as a regex matched against the benchmark ID):cargo bench --bench <name> -- <filter-regex> # example cargo bench --bench my_bench -- fib_\d+
Criterion documents filtering as
cargo bench -- <filter>. [2]
Sources: [1] [2]
Fix JSON contamination and correct Criterion filter wiring.
The --format json output is corrupted. You inherit child stdout/stderr (lines 53–54), so cargo bench and Criterion write directly to the parent's stdout. Since your emit() function also writes JSON via println!() to stdout, the output is mixed and no longer valid JSON.
Additionally, the filter is wired incorrectly. cargo bench --bench <name> selects the bench target binary (e.g., benches/boaw_baseline.rs), not a Criterion benchmark ID pattern. To filter Criterion benchmarks, pass the filter after --: cargo bench --bench <name> -- <regex>.
Fix approach
- // Suppress benchmark stdout to avoid mixing with our formatted output.
- cmd.stdout(std::process::Stdio::inherit());
- cmd.stderr(std::process::Stdio::inherit());
+ // Keep JSON mode clean: suppress child I/O for machine-readability.

change the Command invocation in run (where cmd is built and stdout/stderr are

ensure collect_criterion_results still receives the same filter when parsing

Fix result collection robustness: handle grouped benchmarks, report parse errors, use actual cargo target directory.
Three real problems compound here:
-
Non-recursive scan misses grouped benchmarks: Criterion 0.5 supports benchmark groups (e.g.,
benchmark.group("group_name")), which create nested directories liketarget/criterion/group_name/benchmark_name/new/estimates.json. The pattern*/new/estimates.jsononly catches top-level benchmarks—grouped ones vanish silently. -
Silent parse failures hide corrupted results: The
if let Ok(result) = parse_estimates(...) { results.push(result); }pattern drops any benchmark with broken/incomplete JSON without warning. Users get incomplete result sets with zero indication something went wrong. -
Hardcoded
target/criterionpath breaks when not run from workspace root:Path::new("target/criterion")assumes invocation from the workspace root. Runningecho-cli benchfromcrates/warp-cli/or via cargo workspaces will look in the wrong directory and find nothing.
At minimum: (a) recurse to depth 3 (group/benchmark/new/estimates.json), (b) log/warn on parse errors instead of silently dropping them, (c) resolve actual cargo target_directory (via cargo metadata --format-version 1 | jq .target_directory) or explicitly document that command must run from workspace root.

collect_criterion_results currently does a non-recursive scan which misses
grouped benchmarks, silently drops parse failures, and assumes a hardcoded
"target/criterion" path; fix it by (1) making the scan recursive to find
patterns like group_name/benchmark_name/new/estimates.json (e.g. use WalkDir or
nested read_dir up to depth 3 and match directories whose path ends with
"new/estimates.json"), (2) replace the silent ignore around
parse_estimates(&bench_name, &estimates_path) with error handling that
logs/warns the file path and parse error (use the project logger or
eprintln!/tracing::warn! so corrupted JSON is reported), and (3) stop relying on
a literal Path::new("target/criterion") and instead resolve the Cargo target
directory (e.g. accept a resolved criterion_dir argument from caller or compute
it via cargo metadata / target_directory) so collect_criterion_results works
when run from sub-crates; update the function references
collect_criterion_results, parse_estimates, and the estimates_path construction
accordingly.

--bench <filter> tells cargo to find a bench target by that name. The correct form is `-- <filter>` which forwards the pattern to Criterion as a regex filter. Also fixes the misleading "Suppress benchmark stdout" comment — stdout/stderr are inherited (visible), not suppressed. Extracts build_bench_command() helper with two tests verifying the filter produces ["--", "hotpath"] and omits "--" when absent.
When --expected is provided for a multi-warp WSC file, warps beyond
warp 0 now report "unchecked" instead of falsely claiming "pass".
A stderr warning is emitted when --expected is used with >1 warps.
Removes .to_uppercase() on the Result line so text and JSON output
use consistent lowercase status values ("pass"/"fail"/"unchecked").
Updates --expected help text to document the warp-0-only limitation.
…rting - Remove `colored = "2"` from Cargo.toml (declared but never imported). - Replace .expect() in emit() with match + eprintln fallback so the CLI never panics on JSON serialization failure. - Replace unwrap_or(-1) in bench exit status with signal-aware reporting: on Unix, reports the actual signal number via ExitStatusExt::signal(); on other platforms, reports "unknown termination".
- TASKS-DAG.md: SPEC-PROVENANCE-PAYLOAD.md → SPEC-0005-provenance-payload.md (two occurrences: sub-task title and AC1). - ROADMAP backlog: same stale path in security.md AC1. - SPEC-0005 §5.2: fix domain separation tag byte counts: - echo:provenance_payload:v1\0 = 27 bytes (was 28) - echo:provenance_edge:v1\0 = 24 bytes (was 25) - echo:btr:v1\0 = 12 bytes (correct, unchanged)
Man pages for subcommands now show "echo-cli-bench", "echo-cli-verify", "echo-cli-inspect" in their .TH headers instead of bare "bench", "verify", "inspect". Overrides the clap Command name before passing to clap_mangen::Man::new(). Regenerated docs/man/*.1 via `cargo xtask man-pages`.
- bench.rs: `if let Ok` → `match` with eprintln warning on parse_estimates failure (M3). - bench.rs: guard format_duration for NaN/negative → return "N/A" (M4). - wsc_loader.rs: `unwrap_or(&[])` → `match` with eprintln warning on missing blob (M7). - wsc_loader.rs: add debug_assert!(atts.len() <= 1) at both attachment reconstruction sites (L2). - inspect.rs: BTreeMap/BTreeSet → HashMap/HashSet in count_connected_components (CLI-only, not engine) (L3). - inspect.rs: extract const TREE_MAX_DEPTH = 5 (L4). - lib.rs: remove blanket #![allow(dead_code)], add targeted #[allow(dead_code)] on output module only (L5).
- project-tour-2025-12-28.md: replace "Placeholder CLI home" with actual warp-cli subcommand descriptions (verify, bench, inspect). - ci.yml: remove blank line between warp-geom and warp-wasm rustdoc steps for consistent formatting.
- .ok() → `let _ =` for writeln! Result discard in verify.rs and inspect.rs (idiomatic explicit discard). - .or_insert(0) → .or_default() in inspect.rs type breakdown maps. - pub → pub(crate) on all structs and functions in bench.rs, inspect.rs, verify.rs, and wsc_loader.rs. These types are only used within the binary target. cli.rs types remain pub because xtask imports them via the lib target for man page generation.
Add missing CHANGELOG entries for commits 4-5 and 7-8 (doc path corrections, SPEC-0005 byte counts, man page .TH headers, visibility narrowing, project tour update, CI blank line). Update warp-cli README to note --expected applies to warp 0 only.
…anup - xtask/Cargo.toml: add version = "0.1.0" alongside path dep for warp-cli to satisfy cargo-deny's wildcard dependency check. - README.md: clarify bench description — runs benchmarks AND parses results, not just parses. - xtask man-pages: remove stale echo-cli*.1 files before regeneration so the output directory is an exact snapshot.

False Positive
main.rs:38 — "Does not compile: move cli.command then borrow cli.format"
This is incorrect. The match cli.command { ... ref snapshot ... } arms use ref bindings, which borrow the fields in-place rather than moving cli.command. The code compiles, all 64 tests pass, and ref is the standard Rust pattern for borrowing within a match on an owned value.

The

- Silent failure mode: If

Inline comments:
In `@crates/warp-cli/src/bench.rs`:
- Around line 145-148: The collector re-applies the plain `contains` check on
`filter` against `bench_name`, which can diverge from the execution-side
semantics; fix by parsing/compiling the filter once (e.g., create an
Option<Regex> named `filter_re` near the start of the function where `filter` is
available) and then replace the collector-side `if let Some(f) = filter { if
!bench_name.contains(f) { continue; } }` with a Regex match (`if let Some(re) =
&filter_re { if !re.is_match(&bench_name) { continue; } }`), or if regex support
is not intended, remove the collector-side filtering so the execution-side
semantics are the single source of truth.
In `@docs/man/echo-cli-bench.1`:
- Around line 7-13: Update the SYNOPSIS line so the required value for --filter
is shown to match OPTIONS: change the existing synopsis fragment that currently
reads "\fBecho\-cli\-bench\fR [\fB\-\-filter\fR] ..." to include the argument
placeholder after --filter (i.e. add "\fI<FILTER>\fR" immediately following the
"\fB\-\-filter\fR" token) so the synopsis mirrors the OPTIONS entry for
--filter.
In `@docs/notes/project-tour-2025-12-28.md`:
- Around line 95-104: The tour omits that the warp-ffi crate was removed; add a
short note in the "Tools / adapters" section (or after the crates/warp-benches
entry) stating that `crates/warp-ffi` was removed (PR PP-1) and the C ABI/FFI
path was superseded by the developer CLI (`echo-cli`) approach—either add the
strike-through bullet `~~crates/warp-ffi~~ (removed in PP-1)` with one-line
rationale or append a single-sentence note like “Note: the `warp-ffi` crate was
removed in PR PP-1; the C ABI/FFI integration was superseded by the `echo-cli`
developer CLI.”
- Line 4: Update the document title line "# Echo Project Tour (2025-12-28)" to
reflect the current repository state by replacing the stale date with
"2026-03-04" (or the actual merge date) or adopt a clear version label such as
"Echo Project Tour (post-PP-1)" or "Echo Project Tour v2026-03-04"; ensure the
title change appears at the top of the file so Line 4 accurately matches the
rest of the content that describes the repository as it exists today.
- Around line 105-113: Add a brief entry for SPEC-0005 (Provenance Payload) to
the "Living specs (teaching slice)" list: mention "SPEC-0005 — Provenance
Payload: maps Paper III (AION Foundations) formalism to Echo types, CBOR wire
format with domain separation tags, and SLSA-aligned attestation examples" so
readers know this spec is part of the catalog and its scope; place it alongside
the existing crates/specs entries (referencing SPEC-0005 and "Provenance
Payload" to locate where to insert).
- Around line 99-101: Define the WSC acronym on first use (e.g., "WSC (Warp
Snapshot Columnar)") and clarify that the crate crates/warp-cli builds the
echo-cli binary (explain crate vs binary naming), then expand each command's
description: for verify list its actions (state root hash recomputation,
GraphStore reconstruction, optional --expected validation), for bench describe
parsing Criterion JSON, comfy-table ASCII rendering, --format json support and
regex filter forwarding to Criterion, and for inspect mention snapshot metadata,
graph statistics (type breakdown, connected components via BFS) and the optional
--tree flag for ASCII tree output; also document man page generation via cargo
xtask man-pages and briefly state why this is a "developer CLI" (targets
developer workflows like testing/benchmarking/inspection rather than operator
runtime tasks).
In `@docs/spec/SPEC-0005-provenance-payload.md`:
- Around line 537-540: The spec incorrectly states adding new variants to
TickReceiptRejection is backward-compatible for exhaustive Rust matches; update
the spec to require one of two fixes: either mark the enum TickReceiptRejection
with #[non_exhaustive] so existing exhaustive matches (like the match in
receipt.rs that only handles FootprintConflict) remain valid, or explicitly
document that all consuming code must update pattern matches to handle the new
variants (GuardFailure, PreconditionViolation, ResourceContention) and include a
migration note pointing to the match in receipt.rs that will break compilation
without changes.
- Around line 539-540: The spec's forward-compatibility claim is wrong because
the TickReceiptRejection enum (TickReceiptRejection and its variants
GuardFailure, PreconditionViolation, ResourceContention) uses serde/ciborium
externally-tagged deserialization which will error on unknown variants; fix by
implementing an explicit fallback: change the enum's serde representation to one
that supports #[serde(other)] (e.g., switch to internally- or adjacently-tagged
via #[serde(tag = "...", content = "...")] and add a catch-all variant like
Unknown), or alternatively wrap the rejection in a versioned/optional envelope
or encode the rejection code as an opaque integer/string and add a custom
Deserialize impl that maps unknown codes to an Unknown variant; update
TickReceiptRejection's deserialization accordingly so old decoders ignore/new
variants instead of failing.
In `@TASKS-DAG.md`:
- Around line 157-160: Update TASKS-DAG.md to normalize the renamed label for
issue `#21`: search for any occurrences of the old label variant "(FFI/WASM/CLI)"
or similar and replace them with the new standardized "(WASM/CLI)" (and update
the specific listing for "#21: Spec: Security Contexts (WASM/CLI)"). Ensure all
textual references, headers, and bullet points that mention FFI/WASM/CLI are
updated to the new label so planning docs use a single consistent name.
- Around line 37-50: The TASKS-DAG.md entry for "[`#21`: Spec: Security Contexts
(WASM/CLI)]" was rewritten in-place, breaking the project's append-only
traceability; revert that mutation pattern by restoring the original block and
instead append a new superseding note/block that documents the update (include
timestamp, author/PR reference, and "Supersedes: [`#21`]" or similar), and apply
the same append-only treatment to the other affected entries (around the cited
ranges 75-76, 151-161, 258-274, 665-674); ensure new blocks reference the unique
heading text (e.g., "[`#21`: Spec: Security Contexts (WASM/CLI)]") so readers can
correlate changes without altering historical records.
- Around line 507-510: The BTR model in the task contract still uses an auth_tag
(HMAC/Ed25519) which conflicts with SPEC-0005; update the BTR struct definition
(the `BTR` struct and any code handling `auth_tag`) to replace `auth_tag:
Vec<u8>` with `commit_hash: Hash` and remove any authentication-specific fields
or HMAC/signature computation tied to `auth_tag`; move all signature generation
and verification logic into `ProvenanceEnvelope` (ensure `ProvenanceEnvelope`
now carries the signer(s) and signature(s) and that BTR verification recomputes
and compares `commit_hash` from `h_in`, `h_out`, `initial_state`, `payload`, and
`counter` rather than checking an `auth_tag`), and update any functions/methods
named like `compute_auth_tag`, `verify_btr`, or `compute_btr_hash` to
compute/verify the `commit_hash` and defer signature checks to
`ProvenanceEnvelope`.
In `@xtask/src/main.rs`:
- Around line 495-508: The code currently swallows read_dir and DirEntry errors
via `if let Ok(entries)` and `entries.flatten()`; change it to propagate I/O
failures instead: replace the `if let Ok(entries)` block with `let entries =
std::fs::read_dir(out_dir).with_context(|| format!("failed to read directory
{}", out_dir.display()))?;` and iterate `for entry in entries { let entry =
entry.with_context(|| format!("failed to read directory entry in {}",
out_dir.display()))?; ... }` so that errors from reading the directory and
individual entries are returned (keeping the existing
`remove_file(...).with_context(...)??` call for removal). Include `out_dir` and
the existing `remove_file` call in the new flow.

Outside diff comments:
In @.github/workflows/ci.yml:
- Around line 347-349: The CI step for "rustdoc warnings gate (warp-wasm)" uses
a conditional check if [ -f crates/warp-wasm/Cargo.toml ] which creates
inconsistent behavior versus the unguarded "warp-core" and "warp-geom" steps and
can silently mask a missing crate; either remove the guard so the cargo doc -p
warp-wasm command fails fast like the others, or keep the guard but add a
clarifying comment above that explains why warp-wasm may be absent (e.g.,
partial checkouts/feature branches) to make the intention explicit and
consistent with the other rustdoc steps.
- Around line 1-366: The det-policy.yaml still contains a stale warp-ffi entry
(look for the block with class: DET_CRITICAL and paths: ["crates/warp-ffi/**"])
and AGENTS.md still mentions warp-ffi in the public API list; remove the
warp-ffi det-policy block from det-policy.yaml and delete the warp-ffi mention
from AGENTS.md's public API section (or replace with the correct/current crate
name), and if you want to track remaining occurrences open a follow-up issue
referencing det-policy.yaml and AGENTS.md so the remaining documentation cleanup
can be done later.

symbol "warp-ffi" and "C ABI path", and provide concise migration guidance (what

FFI alternatives and any compatibility notes); ensure the entry appears near the
top of the Unreleased changes and follows the same style as other sections so
downstream users see the breaking change and steps to migrate.

cmd.stderr to std::process::Stdio::null() (or pipe and discard) instead of
inheriting; keep the existing inherit behavior for non-JSON runs—apply this
conditional change to both places where cmd.stdout/cmd.stderr are set (the
blocks around the current cmd.stdout/stdout calls at lines ~68-70 and ~76-83).
- Around line 93-94: The bench discovery is brittle because the call to
collect_criterion_results(Path::new("target/criterion"), filter) assumes a fixed
shallow layout; change collect_criterion_results to perform a recursive (or
depth-limited recursive) walk from the given root and match files by the pattern
"**/new/estimates.json" instead of only scanning immediate children, so the
function (collect_criterion_results) will find Criterion outputs regardless of
directory depth; update any other uses of collect_criterion_results (the
occurrences around the collect_criterion_results call and the block handling
read_dir/ path.join("new").join("estimates.json") in the same module) to rely on
the new recursive behavior and remove shallow-scan logic.
In `@crates/warp-cli/src/inspect.rs`:
- Around line 100-104: The current construction of InspectReport flattens all
per-warp trees into a single list (trees.map(|t|
t.into_iter().flatten().collect())), losing warp identity; change this to
preserve the outer vector of per-warp trees (e.g., keep Vec<Vec<Tree>> or
Option<Vec<Vec<Tree>>> from the variable trees) so each warp's tree remains
separate in InspectReport, and update the text rendering code that prints Tree
to iterate per-warp and emit labeled blocks like "Tree (warp 0):", "Tree (warp
1):" to make multi-warp snapshots unambiguous; update both the construction site
(where InspectReport is built) and the corresponding text renderer (the code
paths referenced around lines ~299-303) to handle the new nested structure.
In `@crates/warp-cli/src/verify.rs`:
- Around line 22-29: The WarpVerifyResult struct currently uses a freeform
status String; change it to structured fields (e.g., a typed enum Status { Pass,
Unchecked, Mismatch } stored as status and a separate optional expected:
Option<String>) so JSON consumers get machine-readable values; update the code
paths in run (where status/expected are set) to assign the enum and expected
details, and move human-readable messages into format_text_report (which should
format mismatch details into text only), ensuring any code that serializes
WarpVerifyResult uses the new fields and that format_text_report accepts the
structured data to produce the previous verbose messages.
- Around line 231-245: The test tampered_wsc_fails currently drops the result
and asserts nothing; update it to capture the expected root from make_test_wsc
(e.g. let (mut wsc_bytes, expected_root) = make_test_wsc()), run the verifier
via run(f.path(), None, &OutputFormat::Text), and then assert the run result
indicates a mismatch by checking the output/error contains the expected_root (or
that the Result is Err and its message references the expected root hash).
Modify references in the test to use expected_root and fail the test if the
verifier does not report the expected-root mismatch.
In `@crates/warp-cli/src/wsc_loader.rs`:
- Around line 44-49: The code currently uses debug_assert! on atts.len() and
then silently truncates with atts.first(), which lets malformed WSCs pass in
release builds; change this to a hard-fail by replacing the debug_assert! with
an explicit runtime check that returns an error (or propagates a Result::Err)
when atts.len() > 1, instead of proceeding with atts.first(); apply the same

- Around line 94-110: The function att_row_to_value currently coerces missing or
invalid attachment data into plausible values (empty blob for atom attachments
and treating any non-atom as Descend), which can silently hide corruption;
change att_row_to_value to fail loudly by returning a Result<AttachmentValue,
Error> (or Option with caller handling) instead of producing a fake
AttachmentValue: when view.blob_for_attachment(att) returns None for an atom
AttRow, return Err with a clear error; when the AttRow tag is not a recognized
atom or descend case, return Err rather than assuming Descend; update callers to
propagate or handle the error accordingly; keep references to AttRow,
att_row_to_value, view.blob_for_attachment, AttachmentValue::Atom /
AttachmentValue::Descend, AtomPayload::new and WarpId to locate the code to

attachments and the Descend branch: add a new test (or augment
roundtrip_with_attachments) that uses GraphStore methods to set an edge
attachment (via the store's edge insertion and attachment API) and set a node
attachment using AttachmentValue::Descend, then produce WSC bytes with
write_wsc_one_warp, reload with WscFile::from_bytes and warp_view, reconstruct
with graph_store_from_warp_view and assert that the
reconstructed.canonical_state_hash() equals the original_hash; reference the

so it aligns with the --expected \fI<EXPECTED>\fR description; target the
SYNOPSIS line for echo-cli-verify in the man page.

- Around line 104-106: The invariant currently requiring
patches[i].header.global_tick == i is incorrect for slices/forks that start at a
non-zero absolute tick; change the wording to require adjacency over the
selected slice instead — e.g., state that for the patches array each entry's
global tick must be contiguous by asserting for all i>0:
patches[i].header.global_tick == patches[i-1].header.global_tick + 1 (or
equivalently patches[i].header.global_tick == start_tick + i when a start_tick
is provided), and remove the assumption that indexing i maps to an absolute
zero-based worldline registration tick; reference patches[i].header.global_tick
and the worldline slice's start_tick in the text.
- Around line 306-323: The early `if slot not in patch.out_slots and (wl, t) !=
(worldline_id, tick): continue` predicate causes the backward-cone traversal to
skip patches that could supply transitive dependencies through other in_slots;
to fix, remove or narrow that top-level continue and instead perform
slot-specific checks during the inner traversal over `in_slot` (i.e., check
`in_slot in prev_patch.out_slots` inside the `for prev_tick in (0..t).rev()`
loop), so `ProvenanceNode` creation, `result_edges.push(...)`, and
`frontier.insert(...)` still discover and record transitive producers for all
`in_slots` rather than being pruned by the global `slot` predicate.
- Around line 201-203: The verification step that recomputes commit_hash uses a
non-existent field "parents" and must be changed to use the exact serialized
inputs defined by the BTR schema (§5.4); update the recipe so recompute
commit_hash from the canonical BTR serialization fields (replace "parents" with
the actual BTR parent field name(s) and any other fields listed in §5.4) and
then assert the result equals btr.commit_hash, ensuring the recompute call and
the assertion reference the same field names used in the BTR spec.

Filter semantics diverge between execution and collection paths.
The same filter string is forwarded to benchmark execution, then re-applied in collection with plain contains. That mismatch can drop valid results for non-literal patterns.
Proposed fix

- if !bench_name.contains(f) {

- }
- }
+ // Keep collector semantics aligned with execution filter.

+ }(Compile once near function start; if regex is intentionally not supported, remove collector-side filtering to avoid semantic drift.)

Update the document date to reflect substantive PR changes.
This PR makes significant changes to the repository state (removes warp-ffi, adds echo-cli with three subcommands, introduces SPEC-0005 Provenance Payload). The "2025-12-28" date in the title is now misleading, especially since Line 6 promises to describe "the repository as it exists today."
Either update the date to 2026-03-04 (or later if final merge differs) or adopt a versioning scheme that clarifies this reflects the post-PP-1 state.

🧹 Nitpick | 🔵 Trivial
Consider documenting the warp-ffi removal for strategic context (optional).
The PR removes the warp-ffi crate entirely and abandons the C ABI/FFI path in favor of the developer CLI approach (per PR objectives). While a tour document doesn't strictly need to document what's NOT in the repository, this is a significant strategic decision about developer tooling architecture.
A brief note in the "Tools / adapters" section (or a new "Removed / deprecated" subsection) could provide helpful context for readers who might encounter references to warp-ffi in git history or older issues.
📝 Optional addition for strategic context
After the crates/warp-benches entry, add:
- ~~`crates/warp-ffi`~~ (removed in PP-1)
- Previously explored C ABI/FFI path for external tool integration; superseded by
the `echo-cli` developer CLI approach.Or add a brief note at the end of the section:

Define WSC, clarify crate vs binary naming, expand command descriptions, and document man pages.
This section has multiple clarity and completeness failures that undermine the document's stated goal of helping readers "orient quickly" (Line 7):
-
WSC acronym undefined: Line 100 uses "WSC integrity" without defining WSC. A tour document targeting newcomers must define all domain-specific acronyms on first use. Is this "Warp Snapshot Columnar"? Don't make readers guess.
-
Crate vs binary name confusion: The section header says
crates/warp-clibut the description says the binary isecho-cli(in parentheses). This relationship is not explained. Does thewarp-clicrate produce anecho-clibinary? Why the naming mismatch? This will confuse readers trying to run commands or understand the workspace structure. -
Command descriptions are severely truncated:
verify: "WSC integrity" omits the core functionality—state root hash recomputation, GraphStore reconstruction, and the optional--expectedvalidation flag. The current description is so generic it tells readers almost nothing about what verification actually does.bench: "Criterion runner/formatter" omits critical details—parsing Criterion JSON, rendering ASCII tables via comfy-table,--format jsonsupport, and regex filter forwarding to Criterion. Readers won't understand this is a post-processor for benchmark results.inspect: "snapshot metadata + ASCII tree" omits graph statistics (type breakdown, connected components via BFS), and doesn't clarify the tree visualization is optional (--treeflag).
-
Man pages not mentioned: The PR adds man page generation via
cargo xtask man-pagesas a major developer-facing deliverable. The tour should document this alongside the CLI commands. -
"Developer CLI" distinction unclear: What makes this a "developer" CLI as opposed to an operator CLI or user CLI? The term is used without explanation.
These gaps violate the document's promise to be a "fast 'become dangerous' map" (Line 6). A newcomer reading this section will not have enough context to understand what these commands do or why they exist.
📖 Proposed fix to improve clarity and completeness
- `crates/warp-cli`
- - Developer CLI (`echo-cli`): `verify` (WSC integrity), `bench` (Criterion
- runner/formatter), `inspect` (snapshot metadata + ASCII tree).
+ - Developer CLI: produces the `echo-cli` binary with three subcommands:
+ - `verify`: loads Warp Snapshot Columnar (WSC) files, validates structural integrity,

+ - `bench`: post-processes Criterion benchmark results from `target/criterion/`,

serde Rust externally tagged enum unknown variant behavior default error handling
💡 Result:
-
Default behavior (externally tagged enum): Serde’s default enum representation is externally tagged (e.g.
{"Request": {...}}). If the input tag/variant name doesn’t match any variant, deserialization fails with an “unknown variant … expected …” error. [1] -
Built-in “unknown variant” fallback:
#[serde(other)]exists, but it is only allowed on a unit variant and only for internally tagged or adjacently tagged enums—so it does not apply to Serde’s default externally tagged enums. [2] -
Common ways to handle “unknown” without error:
-
If your enum is really a “string enum” (the data is just a string), add a catch-all newtype variant and mark it variant-untagged so unknown strings go there:
#[derive(serde::Deserialize)] #[serde(rename_all = "snake_case")] enum PortType { Tcp, Udp, #[serde(untagged)] Unknown(String), }
(
#[serde(untagged)]is allowed on a variant and means “deserialize as just the variant’s data, with no tag.”) [2][3] -
If you can change to internally/adjacently tagged, add a unit fallback:
#[derive(serde::Deserialize)] #[serde(tag = "type")] enum Msg { A { x: i32 }, B { y: i32 }, #[serde(other)] Unknown, }
[2]
-
If you want to accept-and-ignore unknown variants that may carry data, you typically need custom handling; one off-the-shelf helper is
serde_with::rust::deserialize_ignore_any, often combined with a catch-all variant, to consume arbitrary content and return a default. [4]

CBOR enum forward compatibility forward-compatible evolution pattern best practice
💡 Result:
CBOR “enum” forward-compatibility: evolution patterns & best practices
Because CBOR itself is schema-less, forward compatibility is mostly a protocol/design choice, not something CBOR guarantees automatically. RFC 8949 explicitly anticipates unknown tags/simple values and recommends decoders be able to pass them through (or surface them to the application) to enable forward compatibility. [1]
1) Prefer “open” structs/maps + ignore-unknown over top-level enums
Use a CBOR map (often with small integer keys) as the top-level object and specify the ignore-unknown rule: unknown keys are ignored by old readers.
- Many CBOR decoders already behave this way for struct/map decoding (unknown map keys are ignored unless configured to error). [2]
- This is the core evolution mechanism used in multiple CBOR-based specs: add new members, old implementations ignore them. [3]
Implication: Put enums inside an enclosing map field rather than making “the whole message” an enum/union.
2) Encode enums as values with an explicit “unknown” escape hatch
Common forward-compatible encodings:
A. Integer code + “unknown” handling
- Encode the enum as an unsigned integer code.
- In your application model, include an “unknown/unrecognized” case that can store the raw integer.
B. Text string identifiers
- Encode as a CBOR text string (stable identifier like
"in_transit"), and unknown strings round-trip naturally. - This is often more resilient across organizations/languages, at a small size cost.
C. Two-part “extensible enum”
Encode as a small structure, e.g.:
{ 0: <int-code>, 1: <optional text-name>, 2: <extensions...> }
Old readers can still use0and ignore the rest.
3) If you must use a tagged union / variant, make the field optional (or wrap it)
In practice, many code generators/derive macros cannot make a bare enum forward compatible: an unknown variant becomes a hard decode error.
- Example:
minicbor_derivenotes that unknown variants error for enums, and only become forward-tolerant when the enum is in an optional field (unknown variant →None). [4]
So for evolution:
- Avoid “top-level enum messages”.
- Wrap variants in a map/struct with an optional
kind/variantfield, or use an optional union field.
4) Use registries and never renumber
If you use integer codes:
- Treat codes like a registry: never reuse or renumber values.
- Adding new values is fine if old readers can map unknown codes to an “unknown” representation (not an error).
5) For semantic breaks, don’t rely on ignore-unknown—version or new type key
If ignoring a new member would cause “false interoperability” (old readers proceed but misunderstand semantics), create a new top-level message/type discriminator (new map key / new “type” value / new tag) rather than extending in-place.
- This pattern is explicitly called out in CBOR-based protocol guidance: if ignore-unknown isn’t safe for a new “must-understand” member, register a new key/type instead. [3]
Practical rule of thumb
- Extensible map + ignore unknown keys for evolution. [2][3]
- Enum values must have an “unknown” path (or be optional/wrapped), otherwise adding variants is not forward compatible. [4]
- Reserve breaking changes for new type IDs / versions, not “just a new enum value”. [3]

Lines 539–540 claim the wire format is "forward-compatible for encoders" by assuming "decoders that ignore unknown tags." This is unsubstantiated. The TickReceiptRejection enum derives standard serde and uses ciborium's default CBOR deserialization—serde's externally-tagged enums error on unknown variants rather than ignore them. No catch-all variant, custom deserializer, or versioning envelope exists.
When the spec's promised new variants (GuardFailure, PreconditionViolation, ResourceContention) are added to the enum, old decoders will fail immediately on deserialization. To claim forward compatibility, implement an explicit fallback: add a catch-all #[serde(other)] variant (requires switching to internally/adjacently-tagged representation), use an optional/versioned wrapper, or encode the rejection code as an opaque integer with a separate unknown-variant handler.

Do not silently ignore cleanup I/O failures in man-page generation.
The if let Ok(entries) + entries.flatten() path drops directory-read and entry-read errors, so stale files can persist while the command still reports success.

8-41:⚠️ Potential issue | 🟠 MajorSemantic confusion: "Fixed" section for newly-added CLI creates cognitive dissonance.
The changelog structure documents fixes to
echo-cli(lines 8-41) before documenting that the CLI was added (lines 82-105). This violates reader expectations: how can you fix something that doesn't exist yet?The issue stems from mixing iterative PR development history (fixes applied during code review) with user-facing release notes. Changelogs should document the final state delivered to users, not the implementation journey.
Additionally, this section conflates user-facing behavioral fixes (bench filter, verify hash) with internal code quality changes (visibility narrowing, dead code allows, cargo-deny config). Internal refactors don't belong in user-facing changelogs unless they have observable impact.
Recommended structure:
- Merge user-facing behavioral fixes into the main "Added — Developer CLI" section as implementation notes (e.g., "✓ Bench filtering uses Criterion regex, not cargo target selector")
- Delete internal quality bullets (visibility, dead code, cargo-deny) entirely—these are implementation details with zero user impact
- Keep only genuinely user-visible bug fixes that shipped in the final PR (if any existed in a prior commit before this PR)
📋 Proposed consolidation

In `@CHANGELOG.md`:
- Around line 106-113: Move the "Removed" block about the warp-ffi crate so it
sits after the "Added — Provenance Payload Spec" section to follow standard
changelog ordering, remove the internal-only reference "See TASKS-DAG.md `#26`
(Graveyard)" and replace it with a public doc link or remove it entirely, and
expand the item for the breaking change (referencing warp-ffi, RewriteRule, and
Rhai) to include concrete migration guidance: list common C-FFI use cases that
were supported, provide step-by-step migration options to the RewriteRule/Rhai
path (or explicitly state which scenarios are unsupported), and add links to any
migration guide, examples or sample code that demonstrate the equivalent
workflow and API mappings for downstream consumers.
- Around line 82-105: Move the "Added — Developer CLI (echo-cli)" section so it
appears before any "Fixed" sections (i.e., place this Added section before the
existing Fixed entries), add one clarifying sentence about the xtask convention
and how to discover available xtask commands (mentioning that `xtask/` and
`.cargo/config.toml` define repo-specific xtask commands and that `cargo xtask
--help` lists them) and update the bullets under "Verify", "Bench", and
"Inspect" to split flags/arguments from behavior (e.g., "Optional `--expected
<hex>`: Compare reconstructed hash against known value", "`--format text|json`:
Choose output format", "`--filter <pattern>`: Limit benchmarks") so each flag is
its own sub-bullet for scannability; also expand the "Man Pages" bullet to
explicitly note the command `cargo xtask man-pages` generates
docs/man/echo-cli.1 and related man pages.
- Around line 42-68: Remove the PR-iteration noise in lines 42-68: delete the
“Round 2” block and do not list internal test renames or added tests (remove
references to tampered_wsc_does_not_panic and roundtrip_with_edge_attachments /
roundtrip_with_descend_attachment); instead, if any item is genuinely
user-facing (e.g., "Inspect Tree Warp Identity" or the runtime behavior change
described in "WSC Loader Attachment Checks" or the SPEC-0005
verification/derivation fixes), move a single concise user-facing bullet into
the appropriate "Fixed" or "Changed" section with clear behavior description and
include a commit SHA (via git show <sha>) to verify the removal of stale
references (the "warp-ffi" claim) rather than relying on working-tree
inspection; do not mention review rounds or internal QA steps.
- Around line 114-123: Move the SPEC-0005 block so the "Added — Provenance
Payload Spec (PP-1)" section appears before the earlier fix entries that
reference SPEC-0005; clarify the meaning of the "(PP-1)" tag (e.g., milestone,
RFC or internal tracker) next to the heading; split the single dense bullet into
sub-bullets that enumerate the four new types (ProvenancePayload,
BoundaryTransitionRecord, ProvenanceNode, DerivationGraph), the wire
format/CBOR/domain separation note, the two worked examples, the bridge to
ProvenanceStore/PlaybackCursor APIs, and the attestation envelope/SLSA
alignment; and add a verification note that the referenced file
docs/spec/SPEC-0005-provenance-payload.md exists and matches the description.
- Around line 8-123: Update AGENTS.md to remove any reference to the deleted
crate "warp-ffi" (ensure no statement at line ~12 claims it is active), then

Fixed, move the SPEC-0005 "Added" entry above any fixes that reference it (so
references to SPEC-0005 no longer precede its introduction), strip
PR-review/internal notes (entries about test renames, round 2 details, and
trivial CI formatting) from user-facing changelog, and expand the "Removed —
warp-ffi crate deleted" breaking-change entry to include clear migration
guidance for former C FFI users; locate sections by the headings "Unreleased",
"Fixed — Developer CLI (`echo-cli`)", "Fixed — Code Review (PR `#289`, Round 2)",
"Added — Provenance Payload Spec (PP-1)", and the "warp-ffi" removal paragraph
to perform edits.
In `@crates/warp-cli/src/inspect.rs`:
- Around line 119-127: The aggregation currently uses short_hex(&n.node_type)
and short_hex(&e.edge_type) as keys which can collide; change the maps
node_types and edge_types to use the full type ID (e.g., &n.node_type and
&e.edge_type or their String/full hex) as the aggregation key in the loops that
populate node_types and edge_types (leave the short_hex call only where you
render/format the report text), updating uses in WarpStats/report generation
accordingly so counts are grouped by full IDs while display still uses
short_hex.
In `@crates/warp-cli/src/verify.rs`:
- Line 43: The run function should validate and parse the optional expected hex
string into a 32-byte array (not compare the raw strings); if expected is Some,
parse it as hex (accepting upper/lower case), ensure it decodes to exactly 32
bytes and return an error for invalid input, then compare the decoded bytes
against the snapshot hash bytes (rather than comparing strings) so
casing/malformed hex is handled correctly; update the code paths that currently
compare expected directly (references: function run, variable expected, the
snapshot hash comparison logic) to perform a single upfront parse-and-validate
of expected and use byte-wise equality for the final comparison.
In `@docs/phase1-plan.md`:
- Line 47: Update the stale crate name in the scaffold list: replace the
reference "warp-cli" found in the scaffold line "Scaffold crates (`warp-core`,
`warp-wasm`, `warp-cli`)" with "echo-cli" so the document matches the
implemented CLI; also scan the document for any other occurrences of "warp-cli"
and update them to "echo-cli" and adjust surrounding wording if necessary to
reflect the transition.
- Line 67: The demonstration line is ambiguous about what "inspector" refers to;
update the sentence that currently reads "Demonstration: Rhai script triggers
rewrite; inspector shows matching snapshot hash." to explicitly name the
delivered CLI command (for example: use "echo-cli inspect shows matching
snapshot hash") so readers know which tool to run; locate the "Demonstration:
Rhai script triggers rewrite" line and replace "inspector" with the exact CLI
command name you are shipping (e.g., echo-cli inspect).
- Around line 64-66: Replace the vague task text "Port inspector CLI to use
snapshots" with a concrete reference to the delivered CLI subcommands by
updating the line to mention the implemented echo-cli inspect and echo-cli
verify subcommands (and any snapshot-related flags they accept); in other words,
change the description to explicitly state that snapshot-based runtime
inspection and verification were implemented via echo-cli inspect and echo-cli
verify so the doc reflects the actual tooling delivered.

representation and move prose into a separate field: update the WarpVerifyResult
struct to use a stable enum or fixed token strings for status (e.g.,
VerifyStatus::{Pass, Unchecked, Mismatch}) and add a separate optional field
like mismatch_detail or message for human-readable context, then update all
places that set or read status (including the mismatch branch around the current
Line 83 and related code at 77-84, 92-99) to populate the new enum/status and
the detail field appropriately and adjust any serde/JSON serialization to emit
structured fields instead of concatenated text.
In `@crates/warp-cli/src/wsc_loader.rs`:
- Line 23: The loader function graph_store_from_warp_view should not silently
truncate rows that contain multiple attachments; change the function to be
fallible (e.g., return Result<GraphStore, LoaderError>) and validate attachment
multiplicity while iterating WarpView rows (the blocks that currently take the
first attachment at the 44–50 and 61–67/73–74 logic paths). When you encounter
more than one attachment for a row, return an error with context instead of
warning-and-truncating; update callers to propagate the Result and adjust any
helper routines that parse attachment lists to return a clear error on
multiplicity violations.
- Around line 96-111: The function att_row_to_value currently coerces malformed
attachments (missing atom blob -> empty payload, and treating any non-atom tag
as Descend); change att_row_to_value to be fallible (e.g., att_row_to_value ->
Result<AttachmentValue, AttachmentDecodeError>) so it returns an explicit error
when an atom attachment has no blob or when an attachment tag is invalid for the
expected variant; update the body to return Err with a descriptive error
(create/ reuse an AttachmentDecodeError enum) instead of using an empty payload
or silently mapping unknown tags to Descend, and propagate this Result to all
callers so they handle/convert the decode failure appropriately.
In `@docs/spec/SPEC-0005-provenance-payload.md`:
- Around line 554-557: The current paragraph claims adding variants to
FootprintConflict is wire-compatible, but for Rust consumers using
serde/ciborium unknown CBOR enum tags will by default produce a deserialization
error and existing exhaustive match statements will fail to compile or not
handle new variants; update the text to explicitly state this and advise
concrete mitigations: (1) note that default serde/ciborium behavior treats
unknown enum variants as errors, (2) recommend using Rust-side fixes such as
marking the enum non_exhaustive or providing a catch-all variant via serde
attributes (e.g., #[serde(other)] or a fallback wrapper) or documenting that
consumers must implement a fallback, and (3) clarify that encoders/decoders must
be tested for forward/backward compatibility for FootprintConflict handling
rather than assuming ignored unknown tags.

| ### Fixed — Developer CLI (`echo-cli`) | ||
|
|
||
| - **Bench Filter:** `echo-cli bench --filter <pattern>` now passes the filter | ||
| as a Criterion regex (`-- <pattern>`) instead of a `--bench` cargo target | ||
| selector. Previous behavior would look for a bench _target_ named after the | ||
| pattern rather than filtering benchmarks by regex. | ||
| - **Verify Expected Hash:** `--expected` now correctly reports "unchecked" for | ||
| warps 1+ instead of silently claiming "pass". Emits a stderr warning when | ||
| `--expected` is used with multi-warp snapshots. Text and JSON output now | ||
| use consistent lowercase status values. | ||
| - **Unused Dependency:** Removed `colored = "2"` from `warp-cli` (declared but | ||
| never imported). | ||
| - **Output Hardening:** `emit()` no longer panics on JSON serialization failure; | ||
| falls back to stderr. Bench exit status now reports Unix signal numbers | ||
| instead of a misleading `-1`. | ||
| - **Error Handling:** `collect_criterion_results` now logs a warning on | ||
| unparseable `estimates.json` instead of silently skipping. `format_duration` | ||
| returns "N/A" for NaN/negative values. `att_row_to_value` warns on missing | ||
| blob data instead of silent fallback. | ||
| - **Dead Code:** Replaced blanket `#![allow(dead_code)]` on `lib.rs` with | ||
| targeted `#[allow(dead_code)]` on the `output` module only. | ||
| - **Man Page Headers:** Subcommand man pages now use prefixed names | ||
| (`echo-cli-bench`, `echo-cli-verify`, `echo-cli-inspect`) in `.TH` headers | ||
| instead of bare subcommand names. | ||
| - **Visibility:** Narrowed all non-API structs and functions from `pub` to | ||
| `pub(crate)` in bench, verify, inspect, and wsc_loader modules. Only | ||
| `cli.rs` types remain `pub` (required by xtask man page generation). | ||
| - **cargo-deny:** Fixed wildcard dependency error for `warp-cli` in | ||
| `xtask/Cargo.toml` by adding explicit `version = "0.1.0"` alongside | ||
| the path override. | ||
| - **Man Page Cleanup:** `cargo xtask man-pages` now removes stale | ||
| `echo-cli*.1` files before regeneration so the output directory is an | ||
| exact snapshot. | ||
|
|
||
| ### Fixed — Code Review (PR #289, Round 2) | ||
|
|
||
| - **Inspect Tree Warp Identity:** Multi-warp snapshots now label each tree | ||
| section with its warp index (`Tree (warp 0):`, `Tree (warp 1):`) instead of | ||
| flattening all trees into a single unlabeled `Tree:` section. | ||
| - **WSC Loader Attachment Checks:** Replaced `debug_assert!` with runtime | ||
| warnings for attachment multiplicity violations. Previously, release builds | ||
| silently dropped extra attachments; now emits a warning to stderr. | ||
| - **Test Naming:** Renamed `tampered_wsc_fails` to `tampered_wsc_does_not_panic` | ||
| to accurately reflect the test's behavior (no assertion, just no-panic guard). | ||
| - **Test Coverage:** Added `roundtrip_with_edge_attachments` and | ||
| `roundtrip_with_descend_attachment` tests to `wsc_loader.rs`, covering | ||
| previously untested code paths. | ||
| - **SPEC-0005 `global_tick` Invariant:** Reworded from `patches[i].global_tick == i` | ||
| to correctly state contiguity relative to the payload's start tick, since | ||
| payloads can begin at any absolute tick via `from_store(store, wl, 5..10)`. | ||
| - **SPEC-0005 BTR Verification:** Fixed step 5 of the verification algorithm | ||
| to reference the actual hash formula from §5.4 instead of a nonexistent | ||
| `parents` field. | ||
| - **SPEC-0005 Derivation Algorithm:** Fixed backward-cone traversal that dropped | ||
| transitive dependencies. The original filter checked the root query slot at | ||
| every hop; now accepts all frontier nodes unconditionally (they are already | ||
| known-causal) and traces all `in_slots` backward. | ||
| - **Stale `warp-ffi` References:** Removed dead `warp-ffi` entry from | ||
| `det-policy.yaml`, C ABI text from `phase1-plan.md`, and stale CLI names | ||
| from `rust-rhai-ts-division.md`. | ||
|
|
||
| ### Fixed — Docs & CI | ||
|
|
||
| - **TASKS-DAG Spec Path:** `SPEC-PROVENANCE-PAYLOAD.md` → | ||
| `SPEC-0005-provenance-payload.md` in sub-task title and AC1 (two | ||
| occurrences). Same stale path fixed in ROADMAP backlog `security.md`. | ||
| - **SPEC-0005 Byte Counts:** Domain separation tag sizes corrected: | ||
| `echo:provenance_payload:v1\0` = 27 bytes (was 28), | ||
| `echo:provenance_edge:v1\0` = 24 bytes (was 25). | ||
| - **Project Tour:** Updated `warp-cli` description from "Placeholder CLI home" | ||
| to list actual subcommands (verify, bench, inspect). | ||
| - **CI Formatting:** Removed stray blank line between warp-geom and warp-wasm | ||
| rustdoc steps in `ci.yml`. | ||
|
|
||
| ### Added — Developer CLI (`echo-cli`) | ||
|
|
||
| - **CLI Scaffold (`warp-cli`):** Replaced placeholder with full `clap` 4 derive | ||
| subcommand dispatch. Three subcommands: `verify`, `bench`, `inspect`. Global | ||
| `--format text|json` flag for machine-readable output. | ||
| - **Verify Subcommand:** `echo-cli verify <snapshot.wsc>` loads a WSC snapshot, | ||
| validates structural integrity via `validate_wsc`, reconstructs the in-memory | ||
| `GraphStore` from columnar data, and computes the state root hash. Optional | ||
| `--expected <hex>` flag compares against a known hash. | ||
| - **WSC Loader:** New `wsc_loader` module bridges WSC columnar format to | ||
| `GraphStore` — the inverse of `warp_core::wsc::build_one_warp_input`. | ||
| Reconstructs nodes, edges, and attachments from `WarpView`. | ||
| - **Bench Subcommand:** `echo-cli bench [--filter <pattern>]` shells out to | ||
| `cargo bench -p warp-benches`, parses Criterion JSON from | ||
| `target/criterion/*/new/estimates.json`, and renders an ASCII table via | ||
| `comfy-table`. Supports `--format json` for CI integration. | ||
| - **Inspect Subcommand:** `echo-cli inspect <snapshot.wsc> [--tree]` displays | ||
| WSC metadata (tick, schema hash, warp count), graph statistics (node/edge | ||
| counts, type breakdown, connected components via BFS), and optional ASCII | ||
| tree rendering depth-limited to 5 levels. | ||
| - **Man Pages:** Added `clap_mangen`-based man page generation to `xtask`. | ||
| `cargo xtask man-pages` generates `docs/man/echo-cli.1`, | ||
| `echo-cli-verify.1`, `echo-cli-bench.1`, `echo-cli-inspect.1`. | ||
|
|
||
| ### Removed | ||
|
|
||
| - **`warp-ffi` crate deleted:** The C ABI integration path (`crates/warp-ffi`) | ||
| has been removed. The C ABI approach was abandoned in favor of Rust plugin | ||
| extension via `RewriteRule` trait registration and Rhai scripting. See | ||
| TASKS-DAG.md #26 (Graveyard). This is a **BREAKING CHANGE** for any | ||
| downstream code that depended on the C FFI surface. | ||
|
|
||
| ### Added — Provenance Payload Spec (PP-1) | ||
|
|
||
| - **SPEC-0005:** Published `docs/spec/SPEC-0005-provenance-payload.md` mapping | ||
| Paper III (AION Foundations) formalism to concrete Echo types. Defines four | ||
| new types (`ProvenancePayload`, `BoundaryTransitionRecord`, `ProvenanceNode`, | ||
| `DerivationGraph`), wire format with CBOR encoding and domain separation tags, | ||
| two worked examples (3-tick accumulator, branching fork), bridge to existing | ||
| `ProvenanceStore`/`PlaybackCursor` APIs, and attestation envelope with SLSA | ||
| alignment. | ||

Changelog refactoring + AGENTS.md blocking issue before release.
The "Unreleased" section violates changelog conventions (triple "Fixed" fragmentation, section ordering chaos, forward references to SPEC-0005 before introduction, PR archaeology, formatting trivia). These require structural refactoring per the original assessment.
Critical blocking issue: AGENTS.md line 12 still claims warp-ffi is an active crate requiring documentation, directly contradicting the CHANGELOG claim of deletion. This creates an enforced policy document that is false—update AGENTS.md to remove the warp-ffi reference immediately.
Additional structural flaws:
- Lines 8, 42, 69 fragment fixes across three sections (consolidate)
- Lines 55-64, 74-76 reference SPEC-0005 before its introduction (lines 114-123)
- Lines 42-68 document PR review iterations and test naming (remove from user-facing notes)
- Line 79-80 documents a single blank-line removal (zero functional value)
- Breaking change (warp-ffi removal, lines 106-113) lacks migration guidance for C FFI users
Refactor before release: merge three "Fixed" sections, reorder per convention (Added → Removed → Fixed), promote SPEC-0005 addition above its fixes, delete internal review iterations and formatting trivia, strengthen migration guidance for breaking changes.

PR review archaeology doesn't belong in a user-facing changelog.
Lines 42-68 document the iterative code review process ("Round 2"), including test renames, internal test coverage additions, and reviewer-requested fixes. This is PR implementation minutiae, not user-facing release documentation.
Violations:
- Test naming (line 50-51): Renaming
tampered_wsc_fails→tampered_wsc_does_not_panicis internal—users never see test names in releases. - Test coverage (lines 52-54): Adding
roundtrip_with_edge_attachmentstests is implementation QA, not a deliverable. - Forward reference landmine (lines 55-64): SPEC-0005 fixes appear before SPEC-0005 is introduced (lines 114-123), forcing readers to parse fixes for something they haven't encountered yet.
- Stale reference claims (lines 65-67): Per learning, claims about "removed stale warp-ffi references" require verification via
git show <sha>, not working-tree inspection—but the changelog provides no commit SHA for readers to verify.
What belongs in a changelog:
- User-visible bug fixes from prior releases
- Breaking changes with migration paths
- New features with usage examples
- Deprecation warnings
What doesn't:
- PR review iterations
- Test suite internals
- Commit-by-commit fix enumeration
🗑️ Proposed deletion
Delete lines 42-68 entirely. If any fixes have genuine user impact (e.g., inspect multi-warp tree labeling), migrate them to the relevant "Added" or "Fixed" section with user-facing descriptions:

Changelog fragmentation: Third "Fixed" section dilutes focus.
The changelog now has three separate "Fixed" subsections under "Unreleased" (lines 8, 42, 69), creating cognitive overhead and violating the "keep a changelog" convention of consolidating changes by type.
Additional issues:
-
Microscopic formatting trivia (lines 79-80): "Removed stray blank line between warp-geom and warp-wasm rustdoc steps" is a one-character diff with zero functional impact. User-facing changelogs document what changed, not how the CI YAML was formatted.
-
Forward reference recurrence (lines 74-76): SPEC-0005 byte count fixes appear before SPEC-0005 is introduced (lines 114-123), creating the same forward-reference problem flagged in lines 42-68.
-
Mixing severity levels: TASKS-DAG spec path fix (user-impacting doc correction) sits next to blank-line removal (non-impacting formatting).
🔨 Consolidation strategy
- Merge all "Fixed" subsections into a single "Fixed" section (after "Added", before historical releases per conventional ordering).
- Delete formatting trivia (line 79-80).
- Move SPEC-0005 fixes to appear after SPEC-0005 introduction, or merge them inline:

Section ordering: "Added" should precede "Fixed" to establish context.
Lines 82-105 document the addition of echo-cli, but appear after lines 8-41 which document fixes to the same CLI. This violates conventional changelog ordering (Added → Changed → Deprecated → Removed → Fixed → Security) and forces readers to parse fixes before understanding what was added.
Additional observations:
-
Command discoverability (line 103): "cargo xtask man-pages" is referenced without context. Users encountering this in the changelog won't know:
- That
xtaskis a repo-specific convention (per learning: "Usecargo xtask …for repo maintenance") - How to discover available xtask commands
- That
-
Prose density: The bullet points pack multiple concepts into single sentences, harming scannability. Compare:
- Current: "Optional
--expected <hex>flag compares against a known hash." - Scannable: "Optional
--expected <hex>: Compare reconstructed hash against known value."
- Current: "Optional
📐 Ordering fix
- Move this section to line 8, before all "Fixed" sections
- Add xtask context for external readers:
- **Man Pages:** Added `clap_mangen`-based man page generation to `xtask`.
- `cargo xtask man-pages` generates `docs/man/echo-cli.1`,
+ Run `cargo xtask man-pages` (see `.cargo/config.toml` for xtask setup) to generate
+ `docs/man/echo-cli.1`,
`echo-cli-verify.1`, `echo-cli-bench.1`, `echo-cli-inspect.1`.- Break dense bullets into sub-bullets for arguments/flags.
Based on learnings: The learning states "Use cargo xtask … for repo maintenance (see xtask/ and .cargo/config.toml)"—the changelog should help external users discover this convention.

Breaking change lacks actionable migration path for affected users.
Lines 106-113 correctly document the warp-ffi removal as a BREAKING CHANGE (addressing past review comment), but the migration guidance is insufficient for downstream C FFI consumers.
Issues:
-
Section placement: "Removed" appears between two "Added" sections (lines 82-105, 114-123), violating conventional ordering. Standard format: Added → Changed → Deprecated → Removed → Fixed → Security.
-
Internal reference leak (line 111): "See TASKS-DAG.md
#26(Graveyard)" assumes readers have repo access. External users won't find this reference—it's internal task tracking, not public documentation. -
Migration guidance is vague:
- ✓ States what was removed (C ABI path)
- ✓ Names replacement path (RewriteRule/Rhai)
- ✗ No concrete steps: How do C FFI users migrate? Are there docs? Examples? Is this even feasible for their use case, or is this an abandonment?
For a breaking removal, users need:
- What scenarios were C FFI used for?
- How to achieve those scenarios with the new approach
- Link to migration guide or examples
- Statement if some use cases are now unsupported (honest triage)

Use full type IDs for node_types/edge_types aggregation keys.
short_hex keys can collide between distinct type IDs, merging counts in WarpStats. Keep full IDs in report data; shorten only during text rendering.

Validate --expected as a 32-byte hash before comparing.

and parse the optional expected hex string into a 32-byte array (not compare the
raw strings); if expected is Some, parse it as hex (accepting upper/lower case),
ensure it decodes to exactly 32 bytes and return an error for invalid input,
then compare the decoded bytes against the snapshot hash bytes (rather than
comparing strings) so casing/malformed hex is handled correctly; update the code

Incomplete fix from previous review: line 66 still doesn't reference actual echo-cli tooling
The previous review (marked "Addressed in commit 4ff9961") demanded removal of the C ABI path and explicit reference to the new CLI tooling. While line 64's C ABI reference was removed, line 66 still uses the vague phrase "Port inspector CLI to use snapshots" instead of acknowledging the actual delivered echo-cli inspect and echo-cli verify subcommands documented in this PR.
The past review explicitly suggested: "Port/extend developer CLI snapshot tooling (echo-cli inspect/verify) for runtime inspection workflows."
That suggestion was ignored. This line now describes phantom work instead of reflecting what was actually built.
📝 Proposed fix to reflect delivered CLI reality

Vague tool reference in demonstration outcome
"inspector shows matching snapshot hash" doesn't specify which tool. After this PR lands, readers will wonder if "inspector" means echo-cli inspect, some other tooling, or a to-be-built feature. The demonstration line should precisely name the delivered CLI command.
