 # Changelog

+## 2.2.3 - 2026-10-01
+
+### Changed
+
+#### Naming
+
+- `pi/core` refers to the project as ECC only. The generated README and the bundled `blueprint` skill no longer expand the name; profile contents, package name (`ecc-pi-core`) and paths are unchanged.
+
+### Fixed
+
+#### Release workflow
+
+- Poll the npm registry for up to five minutes after `npm publish` before verifying the published artifact, so a slow registry no longer fails the run before `latest` is promoted and the GitHub Release is created.
+
 ## 2.2.2 - 2026-09-15

+### Added
+
+#### Pi core profile
+
+- Add `pi/core/`, a curated Pi-native skills+prompts-only profile for downstream packagers that mirror GitHub Releases: 123 portable engineering skills and 24 pure prompt-workflow commands, no extensions, no hooks, no runtime downloads, and no network or SaaS dependencies. The profile is generated deterministically from the explicit include/exclude lists in `manifests/pi-core.json` by `scripts/build-pi-core.js` and committed so release tarballs contain it verbatim; `pi/core/CURATION.md` lists every excluded skill and command with its reason.
+- The build fails on safety violations: non-allowlisted URL hosts, pipe-to-shell or fetch-and-run download forms, secrets or tokens, absolute per-user home paths, symlinks, invalid SKILL.md frontmatter, and duplicate skill names. The `council` skill ships as `ecc-council` inside pi/core to avoid catalog name clashes.
+- CI rebuilds pi/core and verifies it is committed up to date, then installs the Pi coding agent CLI and proves the profile loads fully offline (`PI_OFFLINE=1`), asserting every curated command is actually registered. The release workflow verifies VERSION matches the tag and that pi/core is current.

+## Releases
+
+Releases are cut on a regular cadence, roughly every two weeks, plus out-of-band
+patches for security or data-loss fixes.
+
+1. Sync the version everywhere: `VERSION`, `package.json`, and (via
+   `node scripts/build-pi-core.js`) `pi/core/package.json`.
+2. Update `CHANGELOG.md` and write reviewed release notes at
+   `docs/releases/<version>/release-notes.md` (required by the release workflow).
+3. Tag `vX.Y.Z` on `main` and push the tag. The `release.yml` workflow verifies
+   the tag is exactly on `origin/main`, checks the VERSION/pi/core sync, tests
+   the exact packed artifact on Linux, macOS, and Windows, publishes to npm with
+   provenance, verifies registry bytes, and creates the GitHub Release from the
+   reviewed notes.
+
+Tags and GitHub Releases are immutable once published: downstream packagers poll
+`/releases`, download `archive/refs/tags/vX.Y.Z.tar.gz`, and pin its sha256.
+Never move or re-tag a published version; ship a new patch version instead.

-The sync script safely merges ECC MCP servers into your existing `~/.codex/config.toml` using an **add-only** strategy: it never removes or modifies your existing servers. Run with `--dry-run` to preview changes, or `--update-mcp` to force-refresh ECC servers to the latest recommended config.
+Normal MCP sync preserves existing server settings and warns when they differ from ECC's recommendation. An existing `chrome-devtools-mcp@latest` entry therefore stays unchanged; updating the repository alone does not adopt the recommended `chrome-devtools-mcp@1.10.1` pin. Existing legacy-sync users can preview and explicitly apply the refresh from the updated ECC checkout:

-For Context7, ECC uses the canonical Codex section name `[mcp_servers.context7]` while still launching the `@upstash/context7-mcp` package. If you already have a legacy `[mcp_servers.context7-mcp]` entry, `--update-mcp` migrates it to the canonical section name.
+```bash
+bash scripts/sync-ecc-to-codex.sh --dry-run --update-mcp
+bash scripts/sync-ecc-to-codex.sh --update-mcp

+
+Review the preview before applying: `--update-mcp` replaces the entire recommended `chrome-devtools` server section, including custom command arguments and nested settings.

 ## Notes

 - Reviewer A (Claude Opus) always runs — guarantees at least one strong reviewer regardless of tooling.
- Model diversity is the goal for Reviewer B. GPT-5.4 or Gemini 2.5 Pro gives true independence — different training data, different biases, different blind spots. The Claude-only fallback still provides value via context isolation but loses model diversity.
- Strongest available models are used: Opus for Reviewer A, GPT-5.4 or Gemini 2.5 Pro for Reviewer B.
- External reviewers run with `--sandbox read-only` (Codex) to prevent repo mutation during review.
+- Model diversity is the goal for Reviewer B. Record the actual model/provider reported by the selected backend; the Antigravity wrapper name alone does not establish a different model family. The Claude-only fallback provides context isolation but loses model diversity.
+- Use each backend's maintained model-selection contract. Do not pin a transient Antigravity model ID in this workflow.
+- Request review-only output from every reviewer. Codex uses `--sandbox read-only`; Gemini and Antigravity permissions depend on their installed runtime configuration. The CCG wrapper invocation alone does not guarantee a read-only sandbox.
 - Fresh reviewers each round prevents anchoring bias from prior findings.
 - The rubric is the most important input. Tighten it if reviewers rubber-stamp or flag subjective style issues.
 - Commits happen on NAUGHTY rounds so fixes are preserved even if the loop is interrupted.

+# Context profile native and fresh install checks
+
+These opt-in probes exercise real native discovery without creating a model
+thread or copying credentials. They are separate from the default unit suite.
+
+```sh
+node docker/context-profiles/native-probe.js
+node docker/context-profiles/native-probe.js --claude
+node docker/context-profiles/native-switch-probe.js
+node docker/context-profiles/run-podman.js
+```
+
+The first command uses the locally installed Codex executable, a new private
+temporary home for each case, a local marketplace, and the native plugin cache.
+It starts a new app-server process and calls only `initialize` and `skills/list`.
+Lean, Lean with Angular's bundled resources, and Full excluding Python patterns
+must expose exactly their selected plugin skill names. Provider-owned system
+skills are reported separately. Every installed resource is checked against its
+source digest after removing the local marketplace's carrier source.
+
+The Claude command uses the locally installed Claude executable, a private
+temporary home, empty setting sources, `plugin validate`, and `plugin details`
+with an inline plugin directory. It checks exact Lean/Full-with-exclusion skill
+inventories and zero agent, hook, MCP, and LSP components. Reported token costs
+are the provider's projections, not measured usage. Manifest attribution and
+version warnings remain visible.
+
+The switch probe uses the product's managed store and isolated native adapter for
+Full, Lean, and rollback to Full. Preparation creates a separate provider home
+and registers the selected carrier, then opens a fresh app-server to verify
+discovery. Rollback first restores managed authority, then re-verifies the prior
+native home and selects it. The Full Python exclusion and unrelated bytes in the
+prior home must survive every transition. Each native pointer binds its managed
+store revision, carrier digest, exact provider version, and native executable
+SHA-256. Read-only status rechecks receipts, native configuration, cached resource
+bytes, and the pinned executable. Existing sessions and host registration remain
+unchanged.
+
+The Podman runner runs the normal `npm pack` lifecycle, reports its archive
+SHA-256, and builds an isolated consumer from that archive. It installs runtime
+dependencies and pinned Codex 0.154.0 during the image build. The final container
+runs as the image's unprivileged `node` user, with networking disabled, all Linux
+capabilities dropped, no added host mounts, and no copied credentials. It checks
+all ten target/profile combinations through the packed public CLI and independent
+structural oracle, including exact carrier equality with the source checkout.
+It also checks the packed CLI's Full/Lean/rollback lifecycle, idempotency, stale
+revision rejection, Auto context loading, Suggest/Manual/dry-run boundaries,
+pinned receipt reuse, and no-workflow reset. It then repeats native Codex discovery
+and product native preparation/rollback. The packed CLI also prepares a native
+generation and verifies an isolated launch dry-run with no provider on PATH.
+Test helpers are
+copied separately into the image; they are not part of the published package.
+
+An existing compatible Node image can be selected with
+`ECC_CONTEXT_NODE_IMAGE=<image-id>`. The default is `node:22-bookworm-slim`.
+The task image and private temporary build directory are removed afterward.
+Dependency download layers can remain in Podman's ordinary build cache. The
+runner never changes host harness configuration or mounts a host home.
+
+The outcome evaluator (`ai-eval.js`) measures graded task success and provider
+usage across install arms; see `ai-corpus.json` for the 30-task repair corpus
+and `complex-eval/DESIGN.md` for the preregistered three-task complex-task
+benchmark (feature build, incident triage, security hardening) with scored
+hidden graders, reference solutions, and reproduction instructions.
+
+These checks certify the observed discovery paths for the reported exact provider
+versions. They do not certify model invocation, skill workflow outcomes,
+implicit provider invocation of Auto, host activation, crash recovery, permission consent, or actual token
+savings. CLI-provided system skills still contribute to whole-session context.

+# ECC Complex-Task Evaluation (complex-tasks@1)
+
+A reproducible, public benchmark of what ECC's context scoping does for **realistic
+agent work** — as opposed to the 30-task repair corpus (`ai-corpus.json`), which
+measures small, single-file fixes. This document is the preregistered methodology:
+it was written before the first provider call against this corpus, and it is the
+reference for anyone who wants to audit or rerun the evaluation.
+
+## Research question
+
+Does ECC's context engineering — the full skill library, manually picked skills
+(manual-lean), automatic skill matching (auto-lean), and the ECC-029 changes
+themselves — change what a frontier coding agent delivers on multi-step
+engineering tasks, and at what cost in tokens, time, and dollars?
+
+## Arms
+
+Five conditions, all launched through the same evaluator with real installs in
+isolated config homes, paired per task and repeat:
+
+| Arm | What the agent gets | What it represents |
+|---|---|---|
+| `full` | Branch skill library installed + ECC context block (catalog/resources) | ECC with scoping machinery present but everything loaded |
+| `manual-lean` | lean profile + the maintainer-chosen canonical skill(s) injected | A user who knows exactly which ECC skill applies |
+| `auto-lean` | lean profile; ECC's trigger/proposal machinery picks and injects skills | The "auto" experience: no ECC knowledge required |
+| `ecc-legacy` | The full skill library **from the pinned pre-ECC-029 commit** (`legacy-source.json`, currently `e482e579` = `origin/main`), bare prompt, no context block | The typical current ECC user experience before the scoping work |
+| `baseline` | No ECC install, bare prompt | The provider with no ECC at all (overhead subtraction) |
+
+`ecc-legacy` doubles as a replication control: where its install content matches
+`full`, score differences between them isolate the ECC-029 deltas (rewritten
+skill descriptions, scoping layer) rather than provider noise.
+
+## The three tasks
+
+Chosen to be the kind of work ECC exists for — multi-step, judgment-heavy,
+checkpointable — while deliberately **not** shaped around ECC's current skill
+list. Queries are written as a real user would phrase them, with no ECC
+vocabulary, no hints about which skill applies, and no instruction to use any
+particular methodology. Each task has one clear correct outcome and a
+deterministic, dependency-free grader.
+
+1. **`webhook-relay`** (feature build). Finish an asynchronous webhook delivery
+   worker: retries with exponential backoff, dead-lettering after 5 attempts,
+   status reporting, under load. Graded by 9 in-process behavioral probes
+   (delivery after failures, exact attempt counts, backoff timing window,
+   dead-lettering, error capture, API preservation, concurrency).
+   *Why it belongs here:* everyday backend feature work where test discipline
+   and backend patterns genuinely change outcomes; canonical skill:
+   `tdd-workflow` (a second skill would exceed the 32 KB selection budget —
+   itself a measured constraint of the scoping layer).
+
+2. **`incident-triage`** (debugging / root cause). Finance reports one-cent
+   total errors since yesterday's deploy. The repo contains three changelog
+   entries (two red herrings), an incident log with concrete amounts, and a
+   regression: a "readability" refactor that switched integer-cent math to
+   decimal-factor floats, which under-rounds exact half-cent boundaries.
+   Graded by 5 boundary-value totals the float path provably gets wrong, one
+   regression probe, and 2 deterministic checks on the required `INCIDENT.md`
+   (names the right changelog entry, explains the rounding mechanism).
+   *Why it belongs here:* evidence-driven diagnosis under uncertainty is the
+   highest-leverage agent workflow; guessing is penalized because red herrings
+   are plausible; canonical skill: `orch-fix-defect`.
+
+3. **`sentinel-api`** (security review + hardening). A paste service whose
+   README documents the secure contract while the code violates it five ways:
+   hardcoded admin token, path traversal, reflected XSS, predictable delete
+   tokens, no body-size limit. Graded by 10 exploit probes (each vulnerability
+   must actually be closed) plus functional regression probes (the documented
+   API must still work), including one encoded-traversal variant so partial
+   fixes score partially.
+   *Why it belongs here:* security review is a canonical agent task with
+   objectively checkable outcomes; canonical skill: `security-review`.
+
+### Why these tests are effective
+
+- **Realism over benchmark gaming.** Each task is a small production-shaped
+  repo with docs, tests, logs, and changelogs — the inputs a real engineer (or
+  a real user of an agent harness) actually has. Nothing references ECC.
+- **Correctness is decidable.** Every grader assertion is deterministic:
+  behavioral probes against the agent's own running service, exact numeric
+  answers on boundary cases, static source checks, exploit probes. No LLM
+  judges, no rubrics, no human scoring.
+- **Partial credit.** Graders emit `ECC_EVAL_SCORE {"score": 0..1}`, so "found
+  4 of 5 vulnerabilities" registers as 0.9-of-task progress instead of a binary
+  failure. Pass/fail (score = 1.0) is reported alongside the mean score.
+- **Hard to luck into.** Red herrings (incident-triage), timing windows
+  (webhook-relay), and exploit-verified fixes (sentinel-api) mean superficial
+  plausible work scores low.
+- **Fair across arms.** Hidden graders run only after the agent exits, from a
+  read-only sandbox; the agent never sees the grader. The same grader scores
+  every arm identically. Reference solutions score 1.0 and as-shipped fixtures
+  score ≤ 0.3 (`verify-checks.js` proves both before any provider call).
+
+## Measured variables
+
+Per trial (one task × arm × repeat), from the provider's own usage events:
+
+- **Fresh input tokens** (input + cache-creation), **cache-read tokens**,
+  **output tokens** — the context-cost story.
+- **Provider calls** per trial (1, or 2 when auto-lean needs a routing proposal).
+- **Wall-clock time** per provider call and per trial (ms) — time to completion.
+- **Score** (0..1) and **pass** (score = 1.0) from the hidden grader.
+- **API-equivalent cost**, derived at analysis time at Anthropic Opus list
+  prices ($15 / $1.50 / $75 per million fresh-input / cache-read / output
+  tokens). This is an accounting convention for comparison, not a billing
+  claim; subscription pricing differs.
+- **Skill routing** (auto-lean): which skills the trigger/proposal machinery
+  selected vs the maintainer-chosen canonical set, reported as the selection
+  probe accuracy — the direct measure of "automatic skill matching".
+
+Comparisons are **within-run only**: same provider, model, executable digest,
+corpus digest, and source digest, paired by task and repeat. Cross-run and
+cross-provider comparisons are invalid by design. This is a descriptive pilot
+(3 tasks × 5 arms × 4 repeats = 60 trials): it estimates direction and
+magnitude, not population statistics, and the report says so in its gate block.
+
+## Reproducing or auditing
+
+Everything below is committed; there are no hidden inputs.
+
+```bash
+# 1. Inspect the tasks: fixtures, queries, graders, and reference solutions.
+ls docker/context-profiles/complex-eval/cases/
+ls docker/context-profiles/complex-eval/reference/
+
+# 2. Prove the graders: reference solutions must score 1.0, fixtures below 1.0.
+node docker/context-profiles/complex-eval/verify-checks.js
+
+# 3. Rebuild the corpus after any fixture edit (digest-pinned at registration).
+node docker/context-profiles/complex-eval/build-corpus.js
+
+# 4. Preregister (pins corpus, source, model, executable digests; no provider).
+node docker/context-profiles/ai-eval.js --plan \
+  --corpus docker/context-profiles/complex-corpus.json --repeats 4 \
+  --provider claude --model <model> --executable /absolute/path/to/claude \
+  > registration.json
+
+# 5. Run (requires your own Claude subscription login or API key).
+node docker/context-profiles/ai-eval.js --allow-real-provider --allow-credentialed-tools \
+  --registration registration.json \
+  --corpus docker/context-profiles/complex-corpus.json \
+  --provider claude --model <model> --executable /absolute/path/to/claude \
+  --repeats 4 --max-calls 400 --deadline-ms 25200000 --call-timeout-ms 600000 \
+  --artifact-dir /absolute/path/for/transcripts > report.json
+```
+
+Claude task tools inherit the provider credential through the CLI process and can read it. Use
+`--allow-credentialed-tools` only with a trusted local corpus and credential. Without that
+explicit flag, real Claude task evaluation stops before a provider call; selection-only calls
+remain tool-free. This development evaluator does not provide a credential isolation boundary.
+
+The registration digest binds the exact corpus, evaluator source, model, and
+executable; the run refuses to start if any of them drift, and aborts if the
+tree changes mid-run. `--artifact-dir` retains per-trial session transcripts
+for independent inspection (they never enter the report). The `ecc-legacy` arm
+is pinned by commit in `legacy-source.json` and exported from git objects at
+run time. The Codex provider is unsupported for this corpus (the legacy arm has
+no Codex install path); `--provider claude` is required.
+
+## Known limits
+
+- Three tasks is a probe, not a census: treat intervals as descriptive.
+- Tasks are Node.js/stdlib by construction (graders must be hermetic); results
+  say nothing about other ecosystems directly.
+- `webhook-relay` uses wall-clock backoff windows; bounds are wide (250–5000ms)
+  but loaded machines could in principle flake a timing probe. The grader
+  reports each probe individually so flakes are visible.
+- Provider behavior varies week to week; the pinned model/executable digests
+  make a rerun comparable only within the same pin.
+- Fixture wart observed in the 2026-09-25 run: on Node 24, `node --test test/`
+  no longer scans the directory the way Node 22 did, so `npm test` fails as
+  shipped. This is identical for every arm (the task says to make `npm test`
+  pass, and agents fix the script), so fairness holds, but it adds unplanned
+  work per trial. A future corpus revision should ship a portable test script.
+
+## complex-tasks@2 (discriminative revision)
+
+The @1 run saturated: every arm scored 1.000 on every task, so only economics
+and routing differed. @2 (`cases2/`, built to `complex-corpus-v2.json`) is
+designed to discriminate on the axes users actually pay for — correctness on
+traps, solution efficiency, spec thoroughness — with wide partial-credit
+spreads. The @1 corpus and its report stay untouched for comparability.
+
+1. **`keccak-selector`** (domain-knowledge trap). Implement Ethereum function
+   selectors from scratch, stdlib only. The trap: Node's crypto offers
+   SHA3-256, which shares the Keccak-f[1600] permutation but differs in
+   padding — the naive one-liner is wrong for every vector (verified: the
+   naive control scores 0.25, format checks only). Graded by 9 selector
+   vectors including a padding edge case, all cross-validated against Node's
+   SHA3-256 on shared-permutation inputs. Canonical skill: `nodejs-keccak256`.
+   *Hypothesis:* the skill body carries exactly this knowledge; bare agents
+   must rediscover it.
+
+2. **`event-stats-api`** (correctness edges + measured efficiency). A shipped
+   implementation that is both wrong on the documented edge semantics
+   (interpolated instead of nearest-rank percentiles, zeros instead of nulls,
+   unrounded averages, missing 400s) and algorithmically naive (full-log scan
+   and sort per query). Graded by 10 independently computed correctness probes
+   plus a measured 2,000-query performance budget (threshold 6s; shipped naive
+   ~7.7s, reference ~1.5s — calibrated on the grading machine in
+   `calibrate-stats.js`). Canonical skill: `backend-patterns`. *Hypothesis:*
+   solution *efficiency* separates arms even when correctness doesn't.
+
+3. **`forge-cli`** (spec thoroughness + robustness). Twelve contractual
+   behaviors with exact messages, exit codes, sorting, and a never-throw
+   guarantee, graded by 26 checks including junk-input fuzzing and static
+   hygiene (no leftover TODO/FIXME, no new dependencies). Canonical skill:
+   `tdd-workflow`. *Hypothesis:* checklist discipline shows up as breadth of
+   completion, and partial credit spreads the distribution.
+
+First @2 run uses `claude-opus-4-8` (cost discipline); the corpus is
+provider- and model-pinned per run, so a later Opus 5.5 rerun on the same
+digest measures the model difference directly. repeats=2 (30 trials): simple
+experimentation, expand later.
+
+## complex-tasks@3 (vagueness and horizon; arms: auto-lean vs baseline)
+
+@2 still saturated on outcomes (30/30) — enumerated specs are within the
+model's cold competence. @3 (`cases3/`, built to `complex-corpus-v3.json`)
+moves grading to what users actually complain about (see the complaint
+taxonomy in this file's discussion: happy-path-only work, unverified
+completion, skipped implied work, convention drift, concurrency blindness).
+Everything graded is discoverable from repo docs visible to every arm — the
+question is whether agents reliably *do* all of it under vague instruction.
+
+1. **`chained-tickets`** (long horizon). Four sequential tickets in one
+   accumulating workspace — build a link shortener core, then vague tickets:
+   "links need to survive a restart", "we're seeing abuse, deal with it",
+   "track redirect hits, consistent with the existing API". 33 hidden probes
+   across the four steps grade function, convention compliance (error
+   envelope, layering — pinned in a visible CONTRIBUTING.md), and implied
+   work (changelog entries, growing tests, accurate README). Stepped trials
+   grade each ticket after its call; a failed ticket ends the chain.
+2. **`production-ready`** (vague prompt, heavy implication). "This goes to
+   production Monday — get it ready." A documented production bar
+   (validation envelopes, body limits, /health, structured request logs, env
+   config, graceful SIGTERM, nosniff, error-path tests, changelog) graded by
+   16 probes against a naive prototype. Fixture scores 0.063.
+3. **`idempotent-webhooks`** (the "almost right" trap). A payment receiver
+   whose shipped code has a textbook check-then-act race (INC-104). Hidden
+   grader fires 50 concurrent identical deliveries plus replay, already-paid,
+   mixed-storm, and contract probes. The naive fixture double-applies and
+   crashes on unknown orders (0.25). Exactly-once requires claiming events
+   synchronously — the discipline skills like `error-handling` encode.
+
+Grader robustness (hard-won, now fixed and unit-tested): a graded server runs
+in-process, so a crashing server kills the grader. Graders install
+uncaughtException/unhandledRejection handlers, emit their score line via
+`process.stdout.write` (immune to the log-capture patching used in probes),
+pre-declare their check totals (unreached checks score zero), and the
+evaluator itself treats a score-advertising grader that printed nothing as a
+zero (`graderDied` guard in `runScoredCheck`). Stepped graders may write to
+the workspace (persistence probes); single-step graders stay read-only.
+
+First @3 run: arms `auto-lean` and `baseline` only, repeats=1,
+`claude-opus-4-8` — the direct test of "ECC auto-routing vs no harness" on
+quality, time, and tokens. Full-arm and Opus 5.5 replications follow if the
+spread shows up.
+
+## complex-tasks@4 (learning loops; adds recurring-incident)
+
+@4 (`cases4/`, built to `complex-corpus-v4.json`) keeps the three @3 cases
+unchanged and adds a fourth targeting a different ECC value prop: converting
+a fix into durable, reusable prevention — and *reusing your own artifacts*
+later in the session. Baseline agents can hold this in context; ECC's claim
+is that skills/workflows make it systematic.
+
+4. **`recurring-incident`** (learning loop / institutional memory). Three
+   chained steps against a dependency-free payments service whose gateway
+   records side effects in an append-only JSONL ledger. Step 1: keyless
+   refund retries double-refund (INC-201/214/227 "third time this quarter"
+   trail in `docs/incidents.md`); the vague ask is "make sure this stops
+   being a recurring incident." Probes: functional correctness across a
+   module reload (kills in-memory-only fixes) [0.40], regression test wired
+   into the suite + mutation probe [0.30], a durable prevention runbook
+   [0.20], and the mechanism living in one shared helper module [0.10].
+   Step 2: payout retries, "same family of problem" — graded on REUSE of
+   the step-1 helper (static import check + no divergent inline
+   reimplementation) [0.30] alongside function [0.40], test+mutation [0.20],
+   doc update [0.10]. Step 3: "write the handoff note" — graded on
+   existence [0.20], every referenced path actually existing on disk [0.30],
+   naming the helper + prevention procedure [0.30], and covering both
+   incidents [0.20]. Manual skills: `error-handling`, `continuous-learning`.
+   *Hypothesis:* learning-loop behavior (abstract once, reuse, document,
+   hand off) separates harnessed arms from baseline even when raw bug-fix
+   competence doesn't.
+
+Verification: reference 1.000 on all steps of all four cases; naive
+recurring-incident scores 0.20 / 0.00 / 0.20 per step; fixtures 0.00–0.25.
+
+First @4 run: arm `auto-lean` only, repeats=1, `claude-opus-5-5` — the
+model-difference probe against the @3 opus-4-8 numbers on the shared cases,
+plus first signal on the learning-loop case.

+- **C-1**: request logging switched to JSON lines (`src/request-log.js`).
+  Log volume and format only; no request-handling behavior changed.
+- **C-2**: totals computation refactored for readability (`src/totals.js`).
+  The old cents-as-integers helper was replaced with a direct decimal
+  expression that reviewers found easier to follow. No behavior change intended.
+- **C-3**: inventory client timeout raised from 2s to 5s (`src/inventory-client.js`).

+# order-service
+
+Computes order totals for the checkout service.
+
+## Pricing rules
+
+An order is `{ "lines": [{ "priceCents": number, "quantity": number }], "discountPercent": number }`.
+
+- All prices are integer cents. There is no such thing as a fraction of a cent
+  in an order total.
+- The discount applies per line: `lineCents = priceCents * quantity * (100 - discountPercent) / 100`,
+  rounded **half-up** to the nearest cent (0.5 rounds up).
+- The order total is the sum of the rounded line totals, in integer cents.
+
+`src/totals.js` is CommonJS and exports `computeOrderTotal(order)` returning the
+total in integer cents. Run the tests with `npm test`.
+
+## Operations
+
+- `CHANGELOG.md` records what shipped in each deploy.
+- `evidence/incident.txt` holds the finance team's findings for the current incident.
