From 056556a9d76ded9ec45fde9a8e7f5fd8c55aa02a Mon Sep 17 00:00:00 2001 From: Eric Alt <13019253+ealt@users.noreply.github.com> Date: Thu, 30 Jul 2026 00:12:34 +0000 Subject: [PATCH 1/5] Cost instrumentation: capture per-role spend, ledger it, report it MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the blindness #343 describes: EDEN could report a run's duration and throughput but not what it cost, so the R2 report hand-estimated ~$35-45 and the live R3 run has no better answer. The executor's Claude Code agent logs already emit `total_cost_usd` per attempt; the platform dropped it. All three of #343's milestones, in one PR because the second two are small deltas on the first's surface. Where cost lives, and why not on the Variant. spec/v0 has no home for spend, verified rather than assumed (#343 asked whether the eval-payload exact-key-match constraint also binds the execution path): on the evaluation path an undeclared key is rejected loudly; on the execution path there is no key validation AND no free-form field, so an extra `cost` key is silently dropped by `submission_from_payload`. Different mechanisms, same conclusion — no smuggling route, and a normative field would mean amending spec MUSTs + conformance, which the balloon-guard on this work put out of scope (the spec-change plan is a comment on #343). So: a non-normative ledger behind the `/_reference/` surface chapter 7 §5 sanctions. `CostLedger` protocol with record/list, a `cost_entry` table on all three backends (SQLite v10 + mirrored Postgres migration), `POST`/`GET /_reference/experiments/{E}/cost` with a matching `StoreClient` pair so a host writes cost identically in-process or across the wire. Kept off the `Store` protocol on purpose (the `ArtifactStore` precedent): a reference extension does not belong in the interface a conforming implementation is measured against. Two ledger properties are load-bearing. First-write-wins on `entry_id` so a re-record after a transport failure cannot double the reported spend — and the key is per-ATTEMPT, not per-task, because a reclaimed and rerun task really did spend twice. Attribution, not aggregation: one row per spend event with the role/task/variant/idea, so every rollup is a read-time reduction. Cost rows carry no event; like artifact metadata they are not bound to any transition, so the chapter-5 §2 invariant has nothing to pair them with. Capture. A host never talks to an LLM itself, so the user's `*_command` reports via two optional keys on the outcome JSON the host already reads (`agent_log`, a stream-json log the host parses; or `cost`, normalized figures) — for the R3-shaped experiment that is one added key naming a log it already writes. The ideator's arrives on its JSON-line terminator, honored on `ideation-error` too since a failed attempt still burned tokens. Recording happens inside the worktree's lifetime and regardless of how the attempt terminalizes. Every failure mode is a no-op, never an error, including an unreachable ledger. Rollup. `summarize()` is a pure reduction into per-role and per-variant totals — not a stored aggregate and not a server-side endpoint, so it cannot drift from the ledger. `cost_report` prints it joined to each variant's status + evaluation payload, which is what makes DCI-per- dollar local instead of a two-source join every consumer rewrites. `entries_missing_cost_usd` keeps a partial total from reading as a complete one. Two refactors the size gate forced, both worth having: `_execute_and_validate` split at the run/validate seam, and the Postgres ledger primitives moved to a `_postgres_cost.py` sibling (the `_postgres_schema.py` precedent) — which also puts the whole non-normative extension behind one labeled file. No slop-allow added. Deferred: cost in checkpoints (#344, needs a normative format bump), a `cost_entry_unpacked` Postgres view (#345). Propose-only on #343: a normative home for cost, AWS cost-allocation tags, an orchestrator budget cap.

New `CostLedger` protocol ([`cost.py`](reference/packages/eden-storage/src/eden_storage/cost.py), [`_ops/cost.py`](reference/packages/eden-storage/src/eden_storage/_ops/cost.py)) with `record_cost` / `list_cost_entries`, a `cost_entry` table on all three backends (SQLite v10 + the mirroring Postgres migration; Postgres primitives in the [`_postgres_cost.py`](reference/packages/eden-storage/src/eden_storage/_postgres_cost.py) sibling), and `POST` / `GET /_reference/experiments/{E}/cost` with a matching `StoreClient` pair so a subprocess-mode host writes cost identically in-process or across the wire. `CostLedger` is kept **off** the `Store` protocol on purpose (the `ArtifactStore` precedent): a reference extension does not belong in the structural interface a conforming implementation is measured against, and the routers cast exactly like the §16 artifact router does. + +**Two ledger properties are load-bearing.** (1) **First-write-wins on `entry_id`** — a host that re-records after a transport failure must not double the reported spend; the caller owns the key and it is per-*attempt*, not per-task, because a reclaimed-and-rerun task really did spend twice (executor keys on its freshly-minted `variant_id`, evaluator on `(task_id, variant_id)`). (2) **Attribution, not aggregation** — one row per spend event carrying role / task / variant / idea, so every rollup is a read-time reduction. Cost rows carry **no event**: like an artifact-metadata row they are not bound to any task/idea/variant transition, so the chapter-5 §2 transactional invariant has nothing to pair them with (and the v0 registry is closed). + +**Capture path.** A worker host never talks to an LLM itself, so the user's `*_command` reports via two OPTIONAL keys on the outcome JSON the host already parses ([worker-host binding](spec/v0/reference-bindings/worker-host-subprocess.md) §11, informative): `agent_log` (a path to a Claude Code `--output-format stream-json` log — the host parses the last `{"type": "result"}` record) or `cost` (already-normalized figures, for non-Claude providers; wins when both are present). For the R3-shaped experiment, adopting this is **one added key naming a log file it already writes**. Shared extraction in [`agent_cost.py`](reference/services/_common/src/eden_service_common/agent_cost.py) drives both the executor and evaluator hosts through one `record_outcome_cost` helper rather than a per-host copy. + +Three behaviors the parser gets right on purpose: it reads the **aggregate** `usage` totals from the terminal `result` record (not per-turn sums, which disagree); it tolerates everything a real log throws at it — interleaved stderr (the reference `execution.py` merges the two streams), a partial final line from a SIGKILLed agent, non-JSON hook noise, and a head past the 8 MiB tail cap; and **every** failure mode is a no-op rather than an error, including an unreachable ledger — cost is bookkeeping *about* an attempt, so a malformed log must never fail an otherwise-good variant. Recording runs inside the per-task worktree's lifetime (a relative `agent_log` resolves against it) and **regardless of how the attempt terminalizes** — money spent on a variant that errored is still money spent, and the ledger says so. + +**Tests.** The happy path runs against a real captured stream-json log from an eden-experiments belief-state-recovery execution task, reduced to one line per record type with prose / session ids / hook output redacted and every `result` number verbatim — so the assertions pin the real field names rather than an invented shape. Ledger semantics (idempotency, cross-backend read order, no-events, experiment-id mismatch) are parametrized across all three backends; the wire round-trip covers filters, `exclude_none` shaping, and the self-gated bearer auth on the two `/_reference/` cost routes (the auth middleware skips `/_reference/`, and one of these routes writes). Host-level tests drive the real `_handle_one` — including the relative-`agent_log` case, which is the only way to catch a regression that moved extraction after worktree cleanup. + +**Refactors the size gate forced (both worth having).** `_execute_and_validate` crossed the 100-line function threshold, so phases 2d–2e split into `_validated_commit_from_outcome`; `postgres.py` crossed 800 SLOC, so the ledger primitives moved to the `_postgres_cost.py` sibling (the `_postgres_schema.py` / `_postgres_views.py` precedent) — which also puts the whole non-normative extension behind one clearly-labeled file. No `# slop-allow` annotations added. + +**Ideator capture (milestone 2).** The ideator's spend arrives on the JSON-line terminator instead of an outcome file — the same two keys, honored on `ideation-error` as well as `ideation-done`, because a failed ideation attempt still burned gateway tokens. Its attempt key is a per-dispatch **nonce** rather than a deterministic id: unlike the executor's `variant_id`, an ideation dispatch has no stable per-attempt identifier, and a task re-dispatched after a reclaim really did spend twice; nothing retries the record call, so one-row-per-dispatch holds by construction rather than by key. `IdeatorSubprocess` gained a read-only `cwd` property so a relative `agent_log` resolves the way the subprocess wrote it. + +The bridge half of milestone 2 is not in this repo: the OpenClaw gateway response the R3 ideator drives is read by `fraxl-ideator.py` in eden-experiments, and whether that response populates an OpenAI-style `usage` object could not be determined from this environment (the gateway runs on the experiment box, which is off-limits while R3 is live). The companion eden-experiments PR normalizes `usage` when present and — per #343's "document what it carries, don't estimate" constraint — logs the response's actual top-level keys once when it is absent, so the next run's log answers the question definitively instead of a heuristic guessing at it. + +**Rollup (milestone 3).** `summarize(experiment_id, entries)` is a pure read-time reduction into per-role and per-variant totals — deliberately **not** a stored aggregate or a server-side summary endpoint, so it cannot drift from the ledger it reads, and one implementation serves both an in-process consumer and one reading over the wire. `CostTotals` carries `entries_missing_cost_usd` so a token-only entry can't make a partial total read as a complete one. `python3 -m eden_service_common.cost_report` prints the rollup joined against each variant's status + evaluation payload (JSON by default — it exists to feed analysis; `--format table` for humans), which is what turns DCI-per-dollar into a local computation instead of a two-source join every consumer rewrites. Auth comes from `EDEN_ADMIN_TOKEN` / `EDEN_BEARER`, never argv. Two accounting properties are asserted rather than assumed: ideation spend (no `variant_id`) counts in `totals` + `by_role` while appearing in no `by_variant` bucket, and spend attributed to a variant the store no longer has is still reported (`status: null`) rather than dropped — understating a run's cost is the one failure this report must not have. Operator-facing docs at [`docs/observability.md`](docs/observability.md) §2.10, including the gaps: labeled-incomplete totals, deadline-killed attempts under-reporting (a killed agent's log has no terminal `result` record), no cost in checkpoints, and inference-only scope. + +**Deferrals.** Checkpoint coverage — cost rows are **not** in checkpoint export/import, because the chapter-10 archive layout is normative and extending it is spec surgery → [#344](https://github.com/ealt/eden/issues/344). A `cost_entry_unpacked` Postgres convenience view for `EDEN_READONLY_STORE_URL` analysis consumers → [#345](https://github.com/ealt/eden/issues/345). A **normative home** for cost (a `Variant` field or first-class record, which would also make it round-trip through checkpoints and be assertable by conformance) is scoped as a comment on #343 rather than done here — the balloon-guard on this work was explicitly "implement within current spec, propose the spec change". AWS cost-allocation tags and an orchestrator budget cap stay **propose-only** on #343: the first needs AWS permissions this work does not have, and the second is a policy surface (chapter 3 §6 decision types + a termination-policy-shaped config block), not a trivial fall-out of the accounting. + +**Validation.** `ruff` / `pyright` / full `pytest` / markdownlint / `spec-xref-check` / `check-rename-discipline` / `check-complexity` all green locally. **Not** run locally: the Postgres-backed rows (no server available in this environment — the `postgres` parametrizations skip; a server-free MRO guard covers the one structural risk the extraction introduced) and the Compose / Helm smokes (no Docker daemon available).

Per-idea attribution. `CostEntry.idea_id` existed but only the executor populated it and the rollup had no per-idea bucket, so the ideation-efficiency question — which expensive ideas produced nothing — was unanswerable. The evaluator stamps it from `variant.idea_id`; the ideator stamps it when a dispatch produced exactly ONE idea, because a dispatch that emitted three spent one indivisible gateway call on all three and both picking one and splitting three ways would be inventions. Those entries stay at role/task level and `by_idea` reports how many it excluded. Landing it meant restructuring `handle_ideation_task` so the single record happens in a `finally` after `_persist_ideas` mints the ids: recording last risks losing a cost row on a crash, recording first risked losing the submission, which is worse. Per-model splits preserved. `modelUsage` was collapsed to one label and dropped entirely for multi-model runs. The whole map is now a `models` list on the entry — per-attempt cost stays per-attempt, the split is structure the read-time reduction slices into `by_model` — deliberately without `num_turns` / `duration_ms`, which belong to the attempt and whose per-model share would be fabricated. `by_model` also covers single-model attempts by synthesizing their one slice, which is exact rather than an allocation. Cache writes are additionally captured per TTL tier from `usage.cache_creation`, which is what makes correct cache pricing possible at all. Derived dollars, labelled as derived. `pricing.py` prices tokens against an operator-supplied rate table for attempts no provider priced. Rates are per token class per model (input / cache write 5m / cache write 1h / cache read / output) in USD per Mtok, because cache reads run ~10x cheaper than fresh input and 1h writes materially dearer than 5m — one blended rate can be wrong by a large multiple. Three properties are enforced, not just documented: nothing writes a computed figure into the ledger (derivation is read-time; `total_cost_usd` keeps meaning "the provider said so"), a table MUST carry `source` + `as_of` and both travel into the report so a figure is auditable against the rates that made it, and an unpriced class is a reported gap never a zero. The shipped template has every rate null so it prices nothing until filled in — no unsourced numbers are baked in. Two structural moves: the rollup got its own `rollup.py` (records -> pricing -> rollup is a clean three-layer stack; inlining pricing would have been an import cycle), and `render_table` split into per-section helpers at the length gate. Two bugs worth naming. `models` as a `tuple` was unbuildable from a JSON array under `strict=True` — it made every multi-model entry both unrecordable and un-POSTable. And a per-model row whose basis said `derived` showed $0 until `DerivedCost.per_model` credited each model its own tokens' cost; "derived, $0.0000" reads as "this model was free".

Rates are **per token class per model** — fresh input, cache write at 5m, cache write at 1h, cache read — in USD per million tokens, because cache reads run ~an order of magnitude cheaper than fresh input and 1h writes materially dearer than 5m, so one blended rate can be wrong by a large multiple. Three properties are enforced rather than documented: nothing writes a computed figure into the ledger (`total_cost_usd` keeps meaning "the provider said so"; derivation is read-time), a table MUST carry `source` + `as_of` and both travel into the report so a figure is auditable against the rates that made it, and an unpriced class is a **reported gap, never a zero** — including cache writes whose TTL tier was never reported, and every rate in the shipped template, which is null on purpose so the template prices nothing until filled in. Buckets carry a `basis` (`reported` / `derived` / `mixed` / `unpriced`), the table render says `DERIVED` in words, and `entries_unpriced` makes a total a stated floor. + +The rollup moved to its own [`rollup.py`](reference/packages/eden-storage/src/eden_storage/rollup.py) (cost records → pricing → rollup is now a clean three-layer stack; the alternative was a cost↔pricing import cycle), and `render_table` split into per-section helpers when it crossed the length gate. + **Deferrals.** Checkpoint coverage — cost rows are **not** in checkpoint export/import, because the chapter-10 archive layout is normative and extending it is spec surgery → [#344](https://github.com/ealt/eden/issues/344).

A **normative home** for cost (a `Variant` field or first-class record, which would also make it round-trip through checkpoints and be assertable by conformance) is scoped as a comment on #343 rather than done here — the balloon-guard on this work was explicitly "implement within current spec, propose the spec change". AWS cost-allocation tags and an orchestrator budget cap stay **propose-only** on #343: the first needs AWS permissions this work does not have, and the second is a policy surface (chapter 3 §6 decision types + a termination-policy-shaped config block), not a trivial fall-out of the accounting. **Validation.** `ruff` / `pyright` / full `pytest` / markdownlint / `spec-xref-check` / `check-rename-discipline` / `check-complexity` all green locally. **Not** run locally: the Postgres-backed rows (no server available in this environment — the `postgres` parametrizations skip; a server-free MRO guard covers the one structural risk the extraction introduced) and the Compose / Helm smokes (no Docker daemon available).

Eric elected to ship without the review. Committing the record rather than deleting it, for two reasons. The absence of a codex-review on a planless chunk should be explicit rather than left for a reviewer to wonder about. And the diagnosis is worth more than the failed round: bare bwrap fails the same way with the harness sandbox off, this shell shares PID 1's namespaces, the project is config-trusted, and there is no seccomp filter — so it is none of the usual suspects. It is the container's capability set (no CAP_SYS_ADMIN, so making / slave returns EPERM), and the leading hypothesis is that installing system bubblewrap flipped Codex off a bundled fallback that had been working. BLOCKED.md carries the verbatim errors, the eliminations, the fix options, and a two-second preflight the skill should adopt so a future session fails fast instead of burning a round that reads nothing. The brief (0.md) is complete and accurate; a retry needs only a working sandbox.

All verification local (fixtures, local store, + repo test suites). +6. **Verify the M1 nuance empirically:** determine whether the exact-key-match + validation that blocks arbitrary eval keys also constrains *execution*-path + submissions, rather than designing around an assumed constraint. +7. **Secrets discipline:** no DSNs or keys on argv or in output. +8. **Gates:** the repo's canonical checks per AGENTS.md; conformance stays + green; new parsing gets unit tests with a real captured stream-json fixture. + +### Follow-up round (requested after the first review pass) + +1. **(F1) Close the per-idea attribution gap:** `CostEntry.idea_id` existed but the + ideator call site didn't pass it, and the rollup had no `by_idea` bucket — so + "which idea cost what" (expensive ideas that produced nothing) was + unanswerable. +2. **(F2) Preserve per-model token splits:** `modelUsage` was collapsed to one label + and dropped entirely for multi-model runs. Keep tokens in/out stratified by + model so a rollup can report `by_model`. "Attribution, not aggregation" — + prefer structure a read-time reduction can slice over a pre-collapsed label. +3. **(F3) Derive dollars from tokens when the provider doesn't report them**, with + caching as the complication to get right: distinct rates for input, output, + **cache writes** (differing by 5-minute vs 1-hour TTL) and **cache reads** + (~an order of magnitude cheaper than input). Rate table needs a rate *per + token class per model*, not one number. Constraints: (a) a derived figure + must never be indistinguishable from a reported one, and a rollup mixing + them must say so; (b) rates are deployment-specific configuration *with + provenance* (source + as-of date), not a hardcoded constant, and an + unpriced/unknown model is an explicit gap, not a silent zero; (c) if a token + class has no rate, report the gap rather than pricing it at 0.

Rationale: `spec/v0` has no home for spend + (chapter-3 submissions carry no cost field; chapter-2 `Variant` has no cost + property; the chapter-5 event registry is closed at v0), and adding one is the + spec surgery constraint 2 forbids. Empirically verified before designing: the + **evaluation** path rejects an undeclared key loudly + (`InvalidPrecondition: evaluation key 'total_cost_usd' is not in the + experiment's evaluation_schema`), while the **execution** path has no key + validation *and* no free-form field — `submission_from_payload` reads named + keys only, so an extra `cost` key is **silently dropped**. +- **`CostLedger` is a separate Protocol, kept off `Store`** (the `ArtifactStore` + precedent): a reference extension shouldn't sit in the structural interface a + *conforming* implementation is measured against. Routers/hosts `cast`. +- **Idempotency is first-write-wins on a per-*attempt* key.** A re-record after + a transport failure must not double reported spend; the key must identify an + attempt, not a task, because a reclaimed-and-rerun task really did spend + twice. Executor keys on its minted `variant_id`, evaluator on + `(task_id, variant_id)`, ideator on a per-dispatch nonce. +- **Cost rows carry no event.** Like artifact metadata they aren't bound to any + task/idea/variant transition, so the chapter-5 §2 transactional invariant has + nothing to pair them with (and the v0 registry is closed). +- **Every capture-path failure is a no-op, never an error** — missing key, + missing/truncated/non-JSON log, deadline-killed agent with no `result` record, + unreachable ledger. Cost is bookkeeping *about* an attempt. +- **Derivation is read-time only.** `CostEntry.total_cost_usd` means "as the + provider reported it" and is never written by a derivation; computed dollars + live in the rollup's separate `derived_cost_usd` with a `basis` label. +- **Attribution stops where it would become invention.** An ideation dispatch + that produced several ideas spent one indivisible call on all of them, so it + is attributed to *no* idea; `by_idea` / `by_variant` / `by_model` are + documented **partial** partitions with `unattributed` counts, and only + `by_role` is complete. + +### Implementation files + +| File | Action | Contract item | +|---|---|---| +| `reference/packages/eden-storage/src/eden_storage/cost.py` | Created | Ledger record: `CostEntry`, `ModelUsage`, `CostRole`/`CostSource`, `cost_entry_id` (items 1, F2) | +| `reference/packages/eden-storage/src/eden_storage/pricing.py` | Created | Rate table with provenance + read-time derivation (item F3) | +| `reference/packages/eden-storage/src/eden_storage/rollup.py` | Created | `summarize()` + `CostTotals`/`CostTokenTotals`/`CostSummary`; per role/variant/idea/model (items 4, F1, F2) | +| `reference/packages/eden-storage/src/eden_storage/_ops/cost.py` | Created | `record_cost` (first-write-wins) / `list_cost_entries` | +| `reference/packages/eden-storage/src/eden_storage/_postgres_cost.py` | Created | Postgres ledger primitives (sibling module; `postgres.py` was at its SLOC budget) | +| `reference/packages/eden-storage/src/eden_storage/protocol.py` | Modified | `CostLedger` Protocol (deliberately not on `Store`) | +| `reference/packages/eden-storage/src/eden_storage/_base.py` | Modified | `_Tx.cost_entries`, abstract primitives, mixin composition + MRO guard | +| `reference/packages/eden-storage/src/eden_storage/{memory,sqlite,postgres}.py` | Modified | Per-backend primitives | +| `reference/packages/eden-storage/src/eden_storage/{_schema,_postgres_schema}.py` | Modified | `cost_entry` table (SQLite v10 + mirrored Postgres migration) | +| `reference/packages/eden-wire/src/eden_wire/routers/reference.py` | Modified | `POST`/`GET /_reference/experiments/{E}/cost`, self-gated bearer auth | +| `reference/packages/eden-wire/src/eden_wire/client.py` | Modified | `StoreClient.record_cost` / `list_cost_entries` | +| `reference/packages/eden-wire/src/eden_wire/models.py` | Modified | `CostEntriesResponse` | +| `reference/services/_common/src/eden_service_common/agent_cost.py` | Created | stream-json parsing + `record_outcome_cost` (items 1, F2) | +| `reference/services/_common/src/eden_service_common/cost_report.py` | Created | Operator report CLI (items 4, F1, F2, F3) | +| `reference/services/executor/src/eden_executor_host/subprocess_mode.py` | Modified | Executor capture; `_validated_commit_from_outcome` split | +| `reference/services/evaluator/src/eden_evaluator_host/subprocess_mode.py` | Modified | Evaluator capture + `idea_id` from variant | +| `reference/services/ideator/src/eden_ideator_host/subprocess_mode.py` | Modified | Ideator capture on the JSON-line terminator; `finally`-record after id minting (item F1) | +| `reference/pricing/price-table.example.json` | Created | Rate-table template — every rate `null`, `as_of: "unset"` | +| `spec/v0/reference-bindings/worker-host-subprocess.md` | Modified | §11 + §11.2 (informative binding chapter only — no normative change) | +| `docs/observability.md`, `AGENTS.md`, `CHANGELOG.md` | Modified | Operator docs, command row, chunk entry | +| `reference/packages/eden-storage/tests/test_cost_{ledger,pricing}.py` | Created | Ledger semantics across all 3 backends; pricing + rollup | +| `reference/packages/eden-wire/tests/test_cost_wire.py` | Created | Wire round-trip + auth | +| `reference/services/_common/tests/test_{agent_cost,cost_report}.py` | Created | Parser (real captured fixture) + report | +| `reference/services/_common/tests/fixtures/claude-agent-log-success.jsonl` | Created | **Real** Claude Code stream-json capture, prose/ids redacted, `result` numbers verbatim | +| `reference/services/{executor,evaluator,ideator}/tests/test_*_subprocess.py` | Modified | Host-level capture tests through the real `_handle_one` | + +### Companion repo (context, not in this diff) + +The producer half lives in `ealt/eden-experiments` +([PR #11](https://github.com/ealt/eden-experiments/pull/11)) because the +platform cannot see what a worker spent — the unit that calls the model is +there.

That was the one action the hypothesis recommended, which is why this is a correction in place rather than a deletion. Two things the measurements replaced it with, both sharper: - "This pod cannot be sandboxed" was too strong. The kernel offers Landlock ABI v7 (errno 0), which needs no CAP_SYS_ADMIN. The accurate statement is that *Codex* can no longer reach the sandbox this pod can provide: `use_linux_sandbox_bwrap` is removed and `use_legacy_landlock` deprecated, and the decisive test on that escape hatch produced no file and reported the sandbox failing before execution. - Codex on this pod has been observed both failing honestly and burning 15,303 tokens, replying DONE, and running nothing. So a round's validity cannot be read off its prose: zero tool-execution events means void, not passing. Recorded as a postflight check alongside the existing preflight suggestion. The correction notes what the original inference got right (the string evidence) and what it skipped (testing the displacement claim before writing it down), and marks the replacement version-change explanation as inference rather than measurement.
