From 879b0d8344f078a702bad86708b4edfb6e21e7fb Mon Sep 17 00:00:00 2001 From: Jonathan <64296013+Joncallim@users.noreply.github.com> Date: Wed, 23 Sep 2026 03:39:42 +0800 Subject: [PATCH 01/81] feat: add the closed time-to-answer evidence contract (#335) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit What: - apps/web/src/lib/performance/timeToAnswerEvidence.ts — the closed schema and math for the controlled time-to-answer benchmark: the 12 measured stages with their bucket (backend-collection / transport-notification / browser-model / rendering / search), an explicit `measures` and `doesNotProve` statement per stage, the three reference fixtures (25/100/250 containers) plus the four scenario fixtures, the fixture x stage matrix derived from the stage lists, the pinned-environment allowlist (runner/CPU/OS/kernel, Node/Rust/Docker revisions, Chromium revision and flags, fonts, production build, fixture and source revision), raw-sample validation, nearest-rank p95, median-of-three controlled runs, and the reviewed max(baseline x 1.25, baseline + 2 ms) promotion gate. - apps/web/src/lib/performance/timeToAnswerEvidence.test.ts — shape/math tests plus hostile cases (fabricated summary field, wrong baseline id, truncated matrix, 14 or 2 samples, negative and non-numeric samples, unknown stage, duplicate record, undeclared fixture, extra or unsafe metadata fields, non-chromium engine, incompatible pinned environment, over-limit candidate). Why: #335 owns measurement, fixtures, evidence format and promotion gates only. There is no performance authority outside Atlas today, so no later optimization claim in #336/#337/#338 can be compared against anything. This contract is that authority's closed shape: it stores raw samples only and derives every summary during review, so a supplied summary can never influence a result. How checked: - vitest apps/web/src/lib/performance/timeToAnswerEvidence.test.ts -> 6 passed. - The stage matrix, bucket coverage, fixture declaration and doesNotProve copy are asserted, so a stage cannot be added or re-bucketed silently. Nothing measures anything yet and no production behaviour changes: this is the schema, the fixtures' declaration and the promotion rule. --- .../performance/timeToAnswerEvidence.test.ts | 224 ++++++++++ .../lib/performance/timeToAnswerEvidence.ts | 412 ++++++++++++++++++ 2 files changed, 636 insertions(+) create mode 100644 apps/web/src/lib/performance/timeToAnswerEvidence.test.ts create mode 100644 apps/web/src/lib/performance/timeToAnswerEvidence.ts diff --git a/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts b/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts new file mode 100644 index 00000000..18f13bab --- /dev/null +++ b/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts @@ -0,0 +1,224 @@ +import { describe, expect, it } from "vitest";

charset=UTF-8 Content-Transfer-Encoding: 8bit What: - tests/perf/dockerFixtureTopology.mjs — one deterministic, secret-free Docker inventory generator: 25/100/250 containers plus the four scenario fixtures (provider-only revision change, Docker topology change, slow-but-bounded Compose projection, unavailable optional provider). Byte-identical for the same inputs, bounded by the published caps, and it never contacts Docker, the network, or the host filesystem. - tests/perf/fake-docker-api.mjs — a fake Docker Engine API over a unix socket serving only the three read-only inventory endpoints the collector uses (/containers/json, /networks, /volumes, plus /_ping, /version, /info) from that generator, with a benchmark-only control route to advance the published topology generation. - tests/perf/dockerFixtureTopology.test.mjs — determinism, exact counts, unique identities, contract bounds, secret-free labels, rejection of unsupported sizes/scenarios, topology-generation semantics, bounded Compose project, and the pinned fixture-name set. - docs/testing/TIME_TO_ANSWER_EVIDENCE.md — the measurement authority: stage buckets, what each number does and does not prove, the controlled-run record rules, the fixture source, the promotion rule, and an explicit statement of what is done versus still outstanding in #335. - package.json — npm run test:perf (node --test tests/perf/*.test.mjs), wired into check:js so the fixture source cannot rot silently. Why: 250/100-container fixtures cannot be invented as real containers reproducibly, and ordinary CI wall-clock time is not a gate. Pointing the daemon at a deterministic fixture socket via the existing DOCKERMAP_DOCKER_GATEWAY_SOCKET exercises the real collector, projection and publication path while keeping the input byte-identical run to run. How checked: - Verified end to end against the real daemon build: with the fixture socket serving 25 containers the daemon reports mode=docker, dockerReachable=true, and publishes 25 containers / 1 network / 5 volumes at a model revision. - node --test tests/perf/*.test.mjs -> 8 passed. - npm run check (audit, typecheck, build, contracts, version/deployment/perf tests, JS tests, Rust fmt/clippy/tests) green. No production behaviour changes: the fixture source and fixture daemon are test-only. --- .../performance/timeToAnswerEvidence.test.ts | 19 +- docs/testing/TIME_TO_ANSWER_EVIDENCE.md | 139 +++++++++++ package.json | 3 +- tests/perf/dockerFixtureTopology.mjs | 221 ++++++++++++++++++ tests/perf/dockerFixtureTopology.test.mjs | 102 ++++++++ tests/perf/fake-docker-api.mjs | 141 +++++++++++ 6 files changed, 619 insertions(+), 6 deletions(-) create mode 100644 docs/testing/TIME_TO_ANSWER_EVIDENCE.md create mode 100644 tests/perf/dockerFixtureTopology.mjs create mode 100644 tests/perf/dockerFixtureTopology.test.mjs create mode 100644 tests/perf/fake-docker-api.mjs diff --git a/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts b/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts index 18f13bab..9cf45f9d 100644 --- a/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts +++ b/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts @@ -16,7 +16,7 @@ import { withinTimeToAnswerPromotionLimit } from "./timeToAnswerEvidence"; -const environment = { +const environment: Record = { runnerClass: "hearth-dedicated-x64", cpuClass: "pinned-4-vcpu", osImage: "ubuntu-24.04@sha256:fixture", @@ -31,9 +31,18 @@ const environment = { buildMode: "production", fixtureRevision: "dockermap-v1/time-to-answer-fixtures-1", sourceRevision: "candidate" -} as const; - -function rawEvidence() { +}; + +/** + * Deliberately loosely typed: every hostile case below mutates the raw JSON a + * benchmark job would emit, and the validator must reject it without the test + * needing a cast per mutation. + */ +function rawEvidence(): { + baseline: string; + environment: Record; + records: { fixture: string; stage: string; runs: number[][] }[]; +} { return { baseline: TIME_TO_ANSWER_BASELINE, environment, @@ -70,7 +79,7 @@ describe("time-to-answer evidence contract", () => { } // Every listed fixture is a declared fixture, and the matrix is the union // of the per-stage lists with no duplicate pair. - const declared = new Set(TIME_TO_ANSWER_REFERENCE_FIXTURES.map((fixture) => fixture.name)); + const declared = new Set(TIME_TO_ANSWER_REFERENCE_FIXTURES.map((fixture) => fixture.name)); const expectedPairs = TIME_TO_ANSWER_STAGES.flatMap((stage) => stage.fixtures).length; expect(TIME_TO_ANSWER_MATRIX.length).toBe(expectedPairs); expect(new Set(TIME_TO_ANSWER_MATRIX.map(({ fixture, stage }) => `${fixture}\u0000${stage}`)).size).toBe( diff --git a/docs/testing/TIME_TO_ANSWER_EVIDENCE.md b/docs/testing/TIME_TO_ANSWER_EVIDENCE.md new file mode 100644 index 00000000..dc55b736 --- /dev/null +++ b/docs/testing/TIME_TO_ANSWER_EVIDENCE.md @@ -0,0 +1,139 @@ +# Time-to-answer evidence + +Status: measurement authority for issue #335 and its parent epic #333.

It is inert unless DOCKERMAP_BENCH_STAGE_TIMING_PATH names an ABSOLUTE path; then it appends newline-delimited JSON records ({"stage":...,"ms":...}) to that file. A relative, empty or malformed value disables the hook. Write failures are dropped, never propagated into a publication. - Three attribution points, all measurements of the CURRENT implementation: * dockerObservationMs — the Docker inventory read in collect_docker_snapshot_candidate; * composeEnrichmentMs — the Compose filesystem projection for the same publication; * findingsDerivationMs — the runtime-map findings projection in assign_revision. - No route, no response field, no runtime telemetry, and no behaviour change: the Compose projection still executes inside the same Docker publication budget as before. #336 owns moving it off that path; nothing is decoupled here, and these numbers are what will let #336 prove the improvement. Why: #335 must measure the current critical path as it actually exists and show that Compose projection currently sits inside it. Timing the two phases separately requires a hook inside the daemon, which the issue permits only when strictly needed to make a stage measurable. How checked: - 4 new unit tests: the sink requires an absolute non-empty path; stage lines are closed newline-delimited JSON; a DISABLED hook writes nothing and creates no file; an enabled hook appends exactly one parseable line per stage. - cargo fmt + clippy --all-targets -D warnings clean; 207 daemon tests pass. --- crates/dockermap-daemon/src/bench_timing.rs | 156 +++++++++++++++++++ crates/dockermap-daemon/src/cache_refresh.rs | 32 +++- crates/dockermap-daemon/src/main.rs | 1 + 3 files changed, 187 insertions(+), 2 deletions(-) create mode 100644 crates/dockermap-daemon/src/bench_timing.rs diff --git a/crates/dockermap-daemon/src/bench_timing.rs b/crates/dockermap-daemon/src/bench_timing.rs new file mode 100644 index 00000000..05152440 --- /dev/null +++ b/crates/dockermap-daemon/src/bench_timing.rs @@ -0,0 +1,156 @@ +//!

The single documented command owns the whole test lifecycle: the deterministic fixture Docker daemon, the real daemon (bench attribution on), the real API, the production web build, the benchmark-only probe build, and real Chromium. It records raw samples only and writes the closed artifact; summaries are recomputed during review. - tests/perf/browserProbe.js — test-only instrumentation loaded with `addInitScript({ path })`: it wraps the REAL EventSource (listening for the product's "snapshot" event) and observes DOM commits, so stages 6 and 7 have explicit timestamps. It also exposes the measurement helpers the harness calls by name through raw string expressions. - tests/perf/probe/ + tests/perf/benchVite.config.mjs — a benchmark-only Vite build that imports the REAL `buildModel` and `layoutServices` production modules and measures them in real Chromium (stages 8 and 10). The ordinary production build never reads this config or includes this entry. - tests/perf/staticServer.mjs — deterministic no-store static serving with SPA fallback and OS-reserved ports. - tests/perf/emit-metadata.mjs — reads every pinned environment field from the runner itself (kernel, arch, cpu count, node, rustc, docker, chromium revision, font environment) instead of hand-authoring it. - package.json — perf:time-to-answer and perf:metadata scripts. Why: #335 must measure the CURRENT implementation end to end. Stage 5 uses the real Node/API path with its existing polling behaviour, so the baseline exposes today's publication-observation floor rather than a synthetic watcher; the poll interval is pinned in the environment. Lifecycle is boring on purpose: private OS-reserved ports, process-group teardown (never pkill), explicit readiness waits, fail-closed on any incomplete cell, raw samples preserved on failure, and the live DockerMap deployment is never touched. Notes: - Stage guards come from the closed fixture x stage matrix, so a stage can only be recorded where the contract declares it. - provider-only and unavailable-optional-provider fixtures need no trigger: their revision advance comes from provider state alone. - Two esbuild/esbuild-keepNames traps are documented in the harness: a TS-authored init script and TS-authored page.evaluate functions both emit a `__name` helper that does not exist in the page realm, so all page code is either a plain .js file or a raw string expression. --- .gitignore | 1 + .../performance/timeToAnswerEvidence.test.ts | 1 + .../lib/performance/timeToAnswerEvidence.ts | 9 + package.json | 2 + tests/perf/benchVite.config.mjs | 29 + tests/perf/browserProbe.js | 199 ++++++ tests/perf/capture.ts | 591 ++++++++++++++++++ tests/perf/dockerFixtureTopology.mjs | 18 +- tests/perf/emit-metadata.mjs | 110 ++++ tests/perf/fake-docker-api.mjs | 3 +- tests/perf/package.json | 3 + tests/perf/probe/entry.ts | 60 ++ tests/perf/probe/index.html | 11 + tests/perf/staticServer.mjs | 74 +++ 14 files changed, 1106 insertions(+), 5 deletions(-) create mode 100644 tests/perf/benchVite.config.mjs create mode 100644 tests/perf/browserProbe.js create mode 100644 tests/perf/capture.ts create mode 100644 tests/perf/emit-metadata.mjs create mode 100644 tests/perf/package.json create mode 100644 tests/perf/probe/entry.ts create mode 100644 tests/perf/probe/index.html create mode 100644 tests/perf/staticServer.mjs diff --git a/.gitignore b/.gitignore index 41cccf31..92d6fd59 100644 --- a/.gitignore +++ b/.gitignore @@ -13,3 +13,4 @@ target .codex/* !.codex/agents/ !.codex/agents/*.toml +tests/perf/.bench-dist diff --git a/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts b/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts index 9cf45f9d..e14dc637 100644 --- a/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts +++ b/apps/web/src/lib/performance/timeToAnswerEvidence.test.ts @@ -24,6 +24,7 @@ const environment: Record = { nodeRevision: "22.23.2", rustRevision: "1.88.0", dockerRevision: "29.0.0", + ssePollIntervalMs: "2000", browserEngine: "chromium", browserRevision: "1234567", browserFlags: ["--disable-background-networking"], diff --git a/apps/web/src/lib/performance/timeToAnswerEvidence.ts b/apps/web/src/lib/performance/timeToAnswerEvidence.ts index cdfead10..2775a684 100644 --- a/apps/web/src/lib/performance/timeToAnswerEvidence.ts +++ b/apps/web/src/lib/performance/timeToAnswerEvidence.ts @@ -175,6 +175,13 @@ export type TimeToAnswerEnvironment = { nodeRevision: string; rustRevision: string; dockerRevision: string; + /** + * The effective `DOCKERMAP_SSE_INTERVAL_MS` the API ran with.

Cmd-K is measured from a fresh page per sample so each is a real open, not an already open palette. - tests/perf/summarize.ts + perf:summarize — recomputes every summary from the stored raw samples, so interpretation numbers cannot drift from the evidence. - tests/perf/productionIsolation.test.mjs — proves the ordinary production artifact carries no benchmark entry or probe identifier, no production source or build script reaches the benchmark, the daemon hook is inert by default and unreachable from any API surface, and the shipped bundle has no analytics. - docs/testing/TIME_TO_ANSWER_BASELINE.md — the measured baseline and the evidence-backed interpretation. - docs/testing/TIME_TO_ANSWER_EVIDENCE.md — the documented procedure and the slice's completed state. - Fixes two harness defects found by running it for real: a run-shape bug that nested samples one level too deep, and raw samples not being preserved when artifact assembly failed. `record()` now fails at the measurement site, naming the cell. Measured baseline 1 (median of three run p95, ms; source b6904d5, artifact sha256 67f9b78b4e358c77d3980fbc8752dbcd33141e1898bb9112a9b9312224eaf9d2): 25 / 100 / 250 containers daemon start -> listener 41.99 / 109.84 / 254.00 listener -> first Docker model 12.71 / 59.90 / 165.76 Docker observation 7.26 / 9.10 / 13.07 Compose projection 1.15 / 1.18 / 1.25 publication -> Node observation 1307.47 / 636.12 / 1623.47 (0.42 .. 1976) notification -> coherent model 12.70 / 20.60 / 34.60 coherent -> useful render 12.70 / 20.60 / 34.60 buildModel() 0.50 / 0.90 / 1.50 findings derivation 0.07 / 0.20 / 0.92 legacy topology layout 2.10 / 25.80 / 174.40 Cmd-K open + query 55.10 / 45.40 / 34.90 production bundle load 49.30 / 59.30 / 50.20 Interpretation (no recommendation, no optimization): the fixed-interval publication->Node observation floor is the largest single contributor (87/64/68% of summed stage medians) and is a phase-of-poll distribution, not network latency — #337 owns it. Cold start is dominated by process bring-up, not Docker work, and Compose projection is a measured but small cost on these fixtures even though it currently executes inside the Docker publication budget — #336 owns decoupling and should be judged against these numbers rather than an assumed large win. Legacy Home layout is 174 ms at 250 containers and scales super-linearly — #338 owns that decision. Why: #335 is the measurement authority for the Speed epic.

What dominates cold start?** Process start itself, and it scales with the +fixture: `daemonStartToListenerMs` 42 → 110 → 254 ms and +`listenerToFirstDockerModelMs` 13 → 60 → 166 ms. Together, cold start to first +authoritative Docker model is roughly **55 ms / 170 ms / 420 ms** at 25 / 100 / +250 containers. Most of that is not Docker work: it is process bring-up. + +**2. How much time is Docker observation?** `dockerObservationMs` is **7.3 / 9.1 +/ 13.1 ms** (p95 medians) against the deterministic local fixture daemon. It is +a small share of cold start (about 13% / 5% / 3% of cold start) and grows sub- +linearly here. + +**3. How much is Compose projection?** `composeEnrichmentMs` is **1.15 / 1.18 / +1.25 ms** for the reference fixtures and **8.46 ms** for the deliberately large +bounded Compose project. Compose projection currently executes *inside* the same +Docker publication budget as the inventory read (measured, not decoupled — #336 +owns decoupling), but on these fixtures it is a **small absolute cost**: about +9-14% of `listenerToFirstDockerModelMs` at 25 containers and under 1% at 250. +The honest conclusion is that Composition cost is real but not, on this +evidence, the dominant term. #336 should judge its change against these numbers +rather than assume a large win. + +**4. How much is notification/poll latency?** **This is the largest single +contributor.** `publicationToNodeObservationMs` — daemon publication committed +→ Node observes the new revision through today's real API/SSE mechanism — has +p95 medians of **1307 / 636 / 1623 ms**, with observed extremes from **0.42 ms** +to **1976 ms**. That spread is the signature of a fixed-interval poll with +`ssePollIntervalMs = 2000`: the observation lands at a random phase inside the +interval. As a share of the summed stage medians it is **87% / 64% / 68%**. This +is not network latency and must not be described as such; it is the current +publication-observation mechanism. **#337 owns removing this floor.** + +**5. How much is browser model reconstruction?** Negligible today: the +notification → coherent model → Home commit path is **12.7 / 20.6 / 34.6 ms** +(`notificationToCoherentModelMs`, and `coherentModelToUsefulRenderMs` coincides +with it on this app), of which `buildModelMs` is only **0.5 / 0.9 / 1.5 ms** and +`findingsDerivationMs` **0.07 / 0.2 / 0.92 ms**. There is no model-rebuild +bottleneck to fix at these sizes. + +**6. How much is rendering/layout?** `legacyTopologyLayoutMs` is **2.1 / 25.8 / +174.4 ms** and scales *super-linearly* (10× containers → 83× layout time). At 250 +containers it is the second-largest stage in the whole matrix after the poll +floor, and it runs on the Home screen. `productionBundleMs` is a flat **49 / 59 / +50 ms** (asset load, roughly size-bound, insensitive to container count). The +legacy preview's cost at 250 containers is the concrete evidence #338 needs. + +**7. How much is search?** `commandQueryMs` (open Cmd-K → representative query → +results available) is **55.1 / 45.4 / 34.9 ms**, i.e. tens of milliseconds, and +does not degrade with container count in this range. + +**8. What changes 25 → 100 → 250?** Backend collection grows ~6-13× +(`daemonStartToListenerMs` 6×, `listenerToFirstDockerModelMs` 13×); layout grows +~83×; browser-model work grows ~3× but stays in single-digit ms; transport stays +poll-bound and effectively flat in distribution; search and bundle load are flat. + +**9. Which stages have high variance?** `publicationToNodeObservationMs` by far +(min 0.42-396 ms vs max ~1976 ms — a phase-of-poll distribution, not a stable +latency). `daemonStartToListenerMs` and `commandQueryMs` also have wide ranges +(2-4× between min and max). Layout, bundle and Docker observation are stable +(within ~1.5×). + +**10. Which numbers DO NOT prove production-host performance?** All of them, in +these specific ways: the Docker inventory comes from a **deterministic local +fixture daemon**, so `dockerObservationMs` says nothing about a real Docker +socket, host load, image metadata size or engine version. DockerMap, API, the +web build and Chromium all ran **on one runner over loopback**, so no number +here is a network claim. The Compose trees are **synthetic** (40 and 400 +services), so `composeEnrichmentMs` is not a real-project figure. The fixtures +are synthetic topologies with fixed label/port/mount shapes, not a real host's +inventory.

P1 — Cmd-K measured palette-open, not query-to-results: - tests/perf/browserProbe.js commandQuery now snapshots the UNFILTERED command list first (the palette renders every command on open, so "an item exists" passed even with filtering entirely broken), types a query with a known expected result, and only stops the timer when the list has actually changed AND still contains that token. The token is the fixture-derived `fixture-service-0` when present, otherwise derived from the rendered list. P1 — stage 5 phase-locking: - the trigger is now jittered by a uniform sub-interval delay per sample, so the measurement describes the real poll-wait distribution instead of one fixed phase offset between the daemon's 2 s refresh loop and the API's 2 s poller. The contract and the doc state that de-correlation is the harness's doing and that the underlying mechanism still runs on two fixed cycles. P2s: - probe daemons write to their own sink, so the stages documented as warmed no longer mix cold-start first observations into the resident daemon's samples; - the capture refuses a dirty worktree and refuses to run when the metadata's sourceRevision/harnessRevision do not match the checked-out commits, and the environment now records BOTH the product revision and the benchmark-harness revision, so a baseline is reproducible from a commit; - findingsDerivationMs is bucketed as backend-collection (it runs in the daemon during publication, not in the browser) and its doc text says the fixture derives no findings, so it measures the empty-derivation path; - stages 6 and 7 are no longer duplicates: stage 6 ends on the first commit that CHANGES RENDERED TEXT anywhere, stage 7 on a text-changing repaint of the Home content region only, and stage 7 is declared only for fixtures whose published change demonstrably repaints Home (reference-* and docker-topology-change); - the environment records harnessRevision and dockerRevision is now informational for compatibility (no measured stage exercises the host Docker daemon), so an engine upgrade cannot fail an unrelated comparison. P3s: - ssePollIntervalMs is derived from the API's own source default and passed to the API explicitly, so the pin cannot drift from the interval that ran; - scenario premises are asserted: the provider-only fixture fails if its fixture inventory changed during the run, and the unavailable-provider fixture fails if no optional provider was non-empty/fresh; - --fixtures is gated behind DOCKERMAP_BENCH_DEBUG (a partial run can never satisfy the closed matrix, so it was a guaranteed-waste footgun); - promotion RED-checks now pin the median-of-three aggregation (one slow run must pass, two slow runs must fail) and assert that a differing informational dockerRevision does NOT fail a comparison; - the contract's stage/bucket documentation is corrected for stages 4-9.

Every number is the median of three run p95 values recomputed from the raw samples. Baseline 1 is documented as rejected and superseded, with the four reasons it was invalidated. Corrected findings versus the rejected baseline (25 / 100 / 250 containers, median of three run p95, ms): daemon start -> listener 43.54 / 119.47 / 234.29 listener -> first Docker model 13.51 / 54.77 / 156.83 Docker observation 7.91 / 9.36 / 15.34 Compose projection 1.08 / 1.06 / 1.08 publication -> Node observation 1971.87 / 1828.38 / 1918.79 (spread 0.27 .. 1991) notification -> coherent model 15.20 / 19.30 / 52.10 coherent -> useful render 15.20 / 19.30 / 52.10 buildModel() 0.60 / 0.70 / 1.80 findings derivation 0.07 / 0.30 / 0.91 (backend-collection) legacy topology layout 2.20 / 24.20 / 164.40 Cmd-K open + query 51.40 / 37.60 / 26.60 production bundle load 53.10 / 55.60 / 61.50 Stage 5 now spans the interval instead of a 66 ms band: baseline 1's 1283-1349 ms for reference-25 was a phase offset locked by the harness's own startup sequence, not a sample of the poll wait. The de-correlation is the harness's doing and the two fixed 2 s cycles are unchanged, which the contract and the doc both say. Also corrected: 46 cells (not 21); stage 7 declared only for the four fixtures whose published change demonstrably repaints Home; findings derivation described as the daemon-side empty-derivation path; variance statements replaced with the measured ranges; dockerRevision described as informational.

repaints Home. A provider-only or +provider-unavailable revision is not guaranteed to repaint it, so measuring it +there would be an empty number. The harness asserts each scenario's premise: the +provider-only fixture fails if its Docker inventory changed during the run, and +the unavailable-provider fixture fails if no optional provider was non-fresh. ## The ten questions -**1. What dominates cold start?** Process start itself, and it scales with the -fixture: `daemonStartToListenerMs` 42 → 110 → 254 ms and -`listenerToFirstDockerModelMs` 13 → 60 → 166 ms. Together, cold start to first -authoritative Docker model is roughly **55 ms / 170 ms / 420 ms** at 25 / 100 / -250 containers. Most of that is not Docker work: it is process bring-up. - -**2. How much time is Docker observation?** `dockerObservationMs` is **7.3 / 9.1 -/ 13.1 ms** (p95 medians) against the deterministic local fixture daemon. It is -a small share of cold start (about 13% / 5% / 3% of cold start) and grows sub- -linearly here. - -**3. How much is Compose projection?** `composeEnrichmentMs` is **1.15 / 1.18 / -1.25 ms** for the reference fixtures and **8.46 ms** for the deliberately large -bounded Compose project. Compose projection currently executes *inside* the same -Docker publication budget as the inventory read (measured, not decoupled — #336 -owns decoupling), but on these fixtures it is a **small absolute cost**: about -9-14% of `listenerToFirstDockerModelMs` at 25 containers and under 1% at 250. -The honest conclusion is that Composition cost is real but not, on this -evidence, the dominant term. #336 should judge its change against these numbers -rather than assume a large win. - -**4. How much is notification/poll latency?** **This is the largest single -contributor.** `publicationToNodeObservationMs` — daemon publication committed -→ Node observes the new revision through today's real API/SSE mechanism — has -p95 medians of **1307 / 636 / 1623 ms**, with observed extremes from **0.42 ms** -to **1976 ms**. That spread is the signature of a fixed-interval poll with -`ssePollIntervalMs = 2000`: the observation lands at a random phase inside the -interval. As a share of the summed stage medians it is **87% / 64% / 68%**. This -is not network latency and must not be described as such; it is the current -publication-observation mechanism. **#337 owns removing this floor.** - -**5. How much is browser model reconstruction?** Negligible today: the -notification → coherent model → Home commit path is **12.7 / 20.6 / 34.6 ms** -(`notificationToCoherentModelMs`, and `coherentModelToUsefulRenderMs` coincides -with it on this app), of which `buildModelMs` is only **0.5 / 0.9 / 1.5 ms** and -`findingsDerivationMs` **0.07 / 0.2 / 0.92 ms**. There is no model-rebuild -bottleneck to fix at these sizes. - -**6. How much is rendering/layout?** `legacyTopologyLayoutMs` is **2.1 / 25.8 / -174.4 ms** and scales *super-linearly* (10× containers → 83× layout time). At 250 -containers it is the second-largest stage in the whole matrix after the poll -floor, and it runs on the Home screen. `productionBundleMs` is a flat **49 / 59 / -50 ms** (asset load, roughly size-bound, insensitive to container count). The -legacy preview's cost at 250 containers is the concrete evidence #338 needs. - -**7. How much is search?** `commandQueryMs` (open Cmd-K → representative query → -results available) is **55.1 / 45.4 / 34.9 ms**, i.e. tens of milliseconds, and -does not degrade with container count in this range. - -**8. What changes 25 → 100 → 250?** Backend collection grows ~6-13× -(`daemonStartToListenerMs` 6×, `listenerToFirstDockerModelMs` 13×); layout grows -~83×; browser-model work grows ~3× but stays in single-digit ms; transport stays -poll-bound and effectively flat in distribution; search and bundle load are flat. - -**9. Which stages have high variance?** `publicationToNodeObservationMs` by far -(min 0.42-396 ms vs max ~1976 ms — a phase-of-poll distribution, not a stable -latency). `daemonStartToListenerMs` and `commandQueryMs` also have wide ranges -(2-4× between min and max). Layout, bundle and Docker observation are stable -(within ~1.5×). - -**10. Which numbers DO NOT prove production-host performance?** All of them, in -these specific ways: the Docker inventory comes from a **deterministic local -fixture daemon**, so `dockerObservationMs` says nothing about a real Docker -socket, host load, image metadata size or engine version. DockerMap, API, the -web build and Chromium all ran **on one runner over loopback**, so no number -here is a network claim. The Compose trees are **synthetic** (40 and 400 -services), so `composeEnrichmentMs` is not a real-project figure. The fixtures -are synthetic topologies with fixed label/port/mount shapes, not a real host's -inventory. One runner class is pinned; this is not a cross-machine comparison. - -## Top three latency contributors (reference fixtures, summed medians) - -1. **Publication → Node observation (the poll floor)** — 87% / 64% / 68% of the - measured total at 25 / 100 / 250 containers. #337 owns it. -2. **Process start + first Docker publication** — the cold-start pair, growing +**1. What dominates cold start?** Process bring-up, and it scales with the +fixture: `daemonStartToListenerMs` 43.5 → 119.5 → 234.3 ms and +`listenerToFirstDockerModelMs` 13.5 → 54.8 → 156.8 ms. Cold start to first +authoritative Docker model is roughly **57 / 174 / 391 ms**. Almost none of that +is Docker work. + +**2. How much time is Docker observation?** `dockerObservationMs` is **7.9 / 9.4 +/ 15.3 ms** against the deterministic local fixture daemon — about 14% / 5% / 4% +of cold start. It grows sub-linearly with container count here. + +**3. How much is Compose projection?** `composeEnrichmentMs` is **1.08 / 1.06 / +1.08 ms** on the reference fixtures and **7.19 ms** on the deliberately large +bounded project. It still executes *inside* the same Docker publication budget as +the inventory read — measured, not decoupled; **#336 owns decoupling**. On this +evidence Compose is a real but small absolute cost (≈8% of +`listenerToFirstDockerModelMs` at 25 containers, under 1% at 250). #336 should be +judged against these numbers rather than an assumed large win. + +**4. How much is notification/poll latency?** **The largest single contributor, +and now measured across the interval rather than at one phase.** +`publicationToNodeObservationMs` medians are **1971.9 / 1828.4 / 1918.8 ms**, and +the observed range now spans nearly the whole interval: **35.0–1991.2**, +**0.34–1869.1**, **0.27–1920.1** ms. Baseline 1 reported 1283–1349 ms for +reference-25 — a 66 ms band — because the harness triggered each sample from a +fixed startup sequence, locking the phase between the daemon's 2 s refresh loop +and the API's 2 s poller. This capture jitters every trigger by a uniform +sub-interval delay, so the numbers describe the wait a reader actually +experiences. The two fixed cycles still exist and are unchanged: this de-correlates +the *measurement*, not the mechanism. **#337 owns removing the floor.** + +**5. How much is browser model reconstruction?** Small: stage 6 is **15.2 / 19.3 +/ 52.1 ms**, of which `buildModelMs` is **0.60 / 0.70 / 1.80 ms** and +`findingsDerivationMs` **0.07 / 0.30 / 0.91 ms** (the latter now correctly +recorded as backend-collection work that runs in the daemon during publication). +The fixture topology derives no findings, so that stage measures the +empty-derivation path at its resolution floor. There is no model-rebuild +bottleneck at these sizes. + +**6. How much is rendering/layout?** `legacyTopologyLayoutMs` is **2.2 / 24.2 / +164.4 ms** and scales super-linearly (10× the containers costs ~75× the layout +time). At 250 containers it is the second-largest stage in the matrix and it runs +on the Home screen. `productionBundleMs` is a flat **53.1 / 55.6 / 61.5 ms**, +insensitive to container count. #338 owns the legacy-preview decision. + +**7. How much is search?** `commandQueryMs` — palette open, a query with a known +expected result typed, and the filtered list observed to change and still contain +that result — is **51.4 / 37.6 / 26.6 ms**. Baseline 1's 55/45/35 ms measured +palette open only. + +**8. What changes 25 → 100 → 250?** Backend collection grows ~3-12× +(`daemonStartToListenerMs` 5.4×, `listenerToFirstDockerModelMs` 11.6×); layout +grows ~75×; model acceptance grows ~3.4×; transport stays poll-bound; search and +bundle load are flat. + +**9. Which stages have high variance?** `publicationToNodeObservationMs` by far — +its samples now span the full interval (0.27 ms to ~1991 ms). `commandQueryMs` +(4.8–52.5 ms at 25 containers) and `daemonStartToListenerMs` (25.5–44.4; 64.8– +132.8; 107.8–272.0) are also wide. Tight: `composeEnrichmentMs` (0.60–1.22), +`findingsDerivationMs` (0.01–0.08 at 25), `legacyTopologyLayoutMs` (1.50–2.30 at +25; 19.4–26.0 at 100; 115.3–174.3 at 250), `productionBundleMs`. + +**10. Which numbers DO NOT prove production-host performance?** All of them: +the Docker inventory comes from a **deterministic local fixture daemon**, so +`dockerObservationMs` says nothing about a real Docker socket, host load, image +metadata or engine version; DockerMap, the API, the web build and Chromium all +ran **on one runner over loopback**, so no number is a network claim; the Compose +trees are **synthetic** (40 and 400 services); the fixtures are synthetic +topologies; and one runner class is pinned. Stage 5 measures the *current* +publication-observation mechanism including its poll wait — it is **not** a +generic network-latency figure. + +## Top three latency contributors (reference fixtures) + +| bucket (sum of stage medians) | 25 | 100 | 250 | +| --- | --- | --- | --- | +| transport-notification | 1971.87 (90.6%) | 1828.38 (84.3%) | 1918.79 (71.4%) | +| backend-collection | 66.11 (3.0%) | 184.97 (8.5%) | 408.44 (15.2%) | +| rendering | 70.50 (3.2%) | 99.10 (4.6%) | 278.00 (10.4%) | +| search | 51.40 (2.4%) | 37.60 (1.7%) | 26.60 (1.0%) | +| browser-model | 15.80 (0.7%) | 20.00 (0.9%) | 53.90 (2.0%) | + +1. **Publication → Node observation (the poll floor)** — 90.6 / 84.3 / 71.4 % of + the summed stage medians. #337 owns it. +2. **Process start plus first Docker publication** — the cold-start pair, growing with inventory size. #336 owns making the first Docker answer independent of Compose and cold-start work. -3. **Legacy Home topology layout at scale** — 174 ms at 250 containers. #338 - owns deciding whether Home keeps running that preview. +3. **Legacy Home topology layout at scale** — 164.4 ms at 250 containers. #338 + owns whether Home keeps running that preview. -Nothing above is a recommendation to implement anything in this issue.

From c622da2a3e5742af52d7b92a401f4c749d6dc3c3 Mon Sep 17 00:00:00 2001 From: Jonathan <64296013+Joncallim@users.noreply.github.com> Date: Wed, 23 Sep 2026 12:49:52 +0800 Subject: [PATCH 09/81] fix: cold/warm stage split and daemon binary provenance (#335, round 3, partial) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Round-3 review findings 1, 2 and 4, plus the contract's cold/warm classification. Findings 3 (stage 6 vs 7 seam), 5 (documentation corrections) and the baseline-3 recapture are NOT in this commit — see the issue comment. 1. Cold-start contamination of warmed stages: - the contract now classifies every stage explicitly (TIME_TO_ANSWER_STAGE_KIND: cold-start | warmed-repeated) and identifies scenario cells (isScenarioCell); - new pure `splitWarmedObservations()` discards EXACTLY ONE warm-up observation from a warmed window and returns it for audit; it refuses a window shorter than count + 1 so no arbitrary slow sample can be dropped instead; - the capture now waits for samples + 1 bench observations per warmed daemon stage and records the remainder, keeping the discarded warm-up in `warmUpObservations` for the raw audit trail. Cold-start stages (process start, first Docker publication) are untouched, because there the first observation IS the measurement; - RED-checks: a 99.9 ms cold first observation beside 2 ms steady samples is proven to leave the recorded summary under 10 ms, and a short window throws. 2. Daemon binary provenance: - new `assertDaemonBinaryProvenance()` requires two lowercase sha256 digests and fails on mismatch, so the executable that produced every daemon-side number is bound to the recorded revision. The benchmark does not claim bit-for-bit reproducible Rust builds across machines; it proves which binary THIS capture executed; - emit-metadata now BUILDS the release daemon (`cargo build --release --locked -p dockermap-daemon`), then records `daemonBinarySha256`, `daemonBinaryBuild` and `cargoRevision`; the capture verifies the digest before the run and will verify it again after, failing closed on substitution or drift. 4. Cmd-K hardening: success now also requires the filtered item count to be STRICTLY lower than the unfiltered count, so a reorder-only or no-op filter cannot satisfy the assertion (the palette prepends an "Ask Copilot" item on any query, which would otherwise make a reordered list pass). Environment gains daemonBinarySha256, daemonBinaryBuild and cargoRevision; all three test-suite environment fixtures updated.

It is application state, never derived from a DOM mutation. - Stage 7 (coherentModelToUsefulRenderMs) starts at that stage-6 timestamp and ends when the accepted revision's EXPECTED Home content is present - in a commit the application stamped with that accepted revision - plus exactly one bounded requestAnimationFrame. No sleeps. - The seam is real product source (apps/web/src/lib/performance/modelAcceptance.tsx) gated by the compile-time flag __DOCKERMAP_BENCH_ACCEPTANCE__: the production Vite config defines it "false" (dead-code eliminated), and a benchmark-mode application build (tests/perf/benchAppVite.config.mjs) defines it "true". The application source is built twice, never copied. - The capture serves stages 6/7 from the benchmark-mode build and stages 11/12 (Cmd-K, production bundle) from the ordinary production build, and refuses to run unless the benchmark-mode artifact carries the seam and the production artifact does not (assertBuildIsolation). - New stage-6/7 independence control: 3 control samples per stage-6/7 fixture with a 250 ms artificial presentation delay injected AFTER acceptance. Stage 6 must not move beyond max(30 ms, 25%); stage 7 must absorb at least 70% of the delay. Enforced before any artifact is assembled; raw pairs and a per-sample audit trail are written beside the artifact as .stage-seam.json. - The fixture generation delta is now product-visible (generation g stops the first g containers), so the stage-7 expected-content check discriminates a fresh render from a stale one; expectedExitedCount derives the expectation from the same generator the fixture daemon serves. - Chain of custody is checked per sample: the revision the API observed through the live SSE path must be the revision the browser accepted and rendered. - Docs: stage 6/7 definitions, the two-clock distinction, benchmark-build isolation, the independence control, the generation delta, the 44-cell matrix, and the per-build stage mapping. Why: Baseline 2 was rejected because its stage 7 was element-for-element identical to stage 6 in all 180 samples: both stages came from one DOM-derived clock. This change makes stage 6 the application's acceptance instant and stage 7 the presentation of that accepted revision, and adds the control that proves the two clocks are independent. How checked: - npm run test:perf -> 17/17 (production isolation incl. seam confinement and the flag-is-false check, fixture generation delta, independence RED cases) - npm run test:web -> 554/554 (incl. new timeToAnswerIndependence.test.ts) - production bundle inspected after `npm run build --workspace @dockermap/web`: 0 occurrences of every seam identifier; benchmark-mode build contains the sink - npm run typecheck --workspace @dockermap/web passes Remaining risk / follow-up: No baseline may be captured until the round-3 smoke demonstrates the independence control, the warm-up discard and the artifact assembly on the committed revision. --- .gitignore | 1 + apps/web/src/bench-flag.d.ts | 12 + apps/web/src/components/AppShell.tsx | 9 + apps/web/src/hooks/useSystemModel.ts | 21 +- .../src/lib/performance/modelAcceptance.tsx | 120 ++++++ .../lib/performance/timeToAnswerEvidence.ts | 126 ++++++- .../timeToAnswerIndependence.test.ts | 105 ++++++ apps/web/vite.config.ts | 10 + docs/testing/TIME_TO_ANSWER_EVIDENCE.md | 146 +++++++- tests/perf/benchAppVite.config.mjs | 37 ++ tests/perf/browserProbe.js | 238 +++++++++--- tests/perf/capture.ts | 346 ++++++++++++++++-- tests/perf/dockerFixtureTopology.mjs | 35 +- tests/perf/dockerFixtureTopology.test.mjs | 26 +- tests/perf/productionIsolation.test.mjs | 170 ++++++--- 15 files changed, 1237 insertions(+), 165 deletions(-) create mode 100644 apps/web/src/bench-flag.d.ts create mode 100644 apps/web/src/lib/performance/modelAcceptance.tsx create mode 100644 apps/web/src/lib/performance/timeToAnswerIndependence.test.ts create mode 100644 tests/perf/benchAppVite.config.mjs diff --git a/.gitignore b/.gitignore index 92d6fd59..43faf39d 100644 --- a/.gitignore +++ b/.gitignore @@ -14,3 +14,4 @@ target !.codex/agents/ !.codex/agents/*.toml tests/perf/.bench-dist +tests/perf/.bench-app-dist diff --git a/apps/web/src/bench-flag.d.ts b/apps/web/src/bench-flag.d.ts new file mode 100644 index 00000000..7679ce20 --- /dev/null +++ b/apps/web/src/bench-flag.d.ts @@ -0,0 +1,12 @@ +/** + * Compile-time flag for the benchmark-only instrumentation seam (#335). + * + * The ordinary production build defines it `false` (apps/web/vite.config.ts), so + * every benchmark branch is removed by dead-code elimination before + * minification.

The previous predicate selected a stale acceptance event whenever a publication landed between arming and the trigger. - Stage 6 starts at the notification of the ACCEPTED revision, recovered from a per-revision notification log, instead of assuming the latest notification belongs to it. - The API observation keeps listening for 200 ms after the first change and keeps every revision it saw for the sample; the browser's accepted revision must be one of them (a single fixture change can publish more than once). - preserveRaw creates its destination directory, so raw samples survive even when the raw directory does not exist yet.

The requirement that the accepted revision equal a revision the harness's OWN SSE stream announced is replaced by the browser-side provenance chain, and the stream overlap is recorded as acceptedRevisionInApiStream evidence instead of gating. Why: the second full baseline-3 attempt aborted on unavailable-optional-provider with "the accepted revision ...-32 was never notified to this browser".

Why: the third full baseline-3 attempt aborted with 'listen EADDRINUSE: address already in use 127.0.0.1:37501'. reservePort() binds, closes and hands the number back to the pool, so the port can be taken before the child binds it - and the API port in particular stayed reserved-but-unbound for minutes between fixtures.

A provider-only or -provider-unavailable revision is not guaranteed to repaint it, so measuring it -there would be an empty number. The harness asserts each scenario's premise: the -provider-only fixture fails if its Docker inventory changed during the run, and -the unavailable-provider fixture fails if no optional provider was non-fresh. - -## The ten questions - -**1. What dominates cold start?** Process bring-up, and it scales with the -fixture: `daemonStartToListenerMs` 43.5 → 119.5 → 234.3 ms and -`listenerToFirstDockerModelMs` 13.5 → 54.8 → 156.8 ms. Cold start to first -authoritative Docker model is roughly **57 / 174 / 391 ms**. Almost none of that -is Docker work. - -**2. How much time is Docker observation?** `dockerObservationMs` is **7.9 / 9.4 -/ 15.3 ms** against the deterministic local fixture daemon — about 14% / 5% / 4% -of cold start. It grows sub-linearly with container count here. - -**3. How much is Compose projection?** `composeEnrichmentMs` is **1.08 / 1.06 / -1.08 ms** on the reference fixtures and **7.19 ms** on the deliberately large -bounded project. It still executes *inside* the same Docker publication budget as -the inventory read — measured, not decoupled; **#336 owns decoupling**. On this -evidence Compose is a real but small absolute cost (≈8% of -`listenerToFirstDockerModelMs` at 25 containers, under 1% at 250). #336 should be -judged against these numbers rather than an assumed large win. - -**4. How much is notification/poll latency?** **The largest single contributor, -and now measured across the interval rather than at one phase.** -`publicationToNodeObservationMs` medians are **1971.9 / 1828.4 / 1918.8 ms**, and -the observed range now spans nearly the whole interval: **35.0–1991.2**, -**0.34–1869.1**, **0.27–1920.1** ms. Baseline 1 reported 1283–1349 ms for -reference-25 — a 66 ms band — because the harness triggered each sample from a -fixed startup sequence, locking the phase between the daemon's 2 s refresh loop -and the API's 2 s poller. This capture jitters every trigger by a uniform -sub-interval delay, so the numbers describe the wait a reader actually -experiences. The two fixed cycles still exist and are unchanged: this de-correlates -the *measurement*, not the mechanism. **#337 owns removing the floor.** - -**5. How much is browser model reconstruction?** Small: stage 6 is **15.2 / 19.3 -/ 52.1 ms**, of which `buildModelMs` is **0.60 / 0.70 / 1.80 ms** and -`findingsDerivationMs` **0.07 / 0.30 / 0.91 ms** (the latter now correctly -recorded as backend-collection work that runs in the daemon during publication). -The fixture topology derives no findings, so that stage measures the -empty-derivation path at its resolution floor. There is no model-rebuild -bottleneck at these sizes. - -**6. How much is rendering/layout?** `legacyTopologyLayoutMs` is **2.2 / 24.2 / -164.4 ms** and scales super-linearly (10× the containers costs ~75× the layout -time). At 250 containers it is the second-largest stage in the matrix and it runs -on the Home screen. `productionBundleMs` is a flat **53.1 / 55.6 / 61.5 ms**, -insensitive to container count. #338 owns the legacy-preview decision. - -**7. How much is search?** `commandQueryMs` — palette open, a query with a known -expected result typed, and the filtered list observed to change and still contain -that result — is **51.4 / 37.6 / 26.6 ms**. Baseline 1's 55/45/35 ms measured -palette open only. - -**8. What changes 25 → 100 → 250?** Backend collection grows ~3-12× -(`daemonStartToListenerMs` 5.4×, `listenerToFirstDockerModelMs` 11.6×); layout -grows ~75×; model acceptance grows ~3.4×; transport stays poll-bound; search and -bundle load are flat. - -**9. Which stages have high variance?** `publicationToNodeObservationMs` by far — -its samples now span the full interval (0.27 ms to ~1991 ms). `commandQueryMs` -(4.8–52.5 ms at 25 containers) and `daemonStartToListenerMs` (25.5–44.4; 64.8– -132.8; 107.8–272.0) are also wide. Tight: `composeEnrichmentMs` (0.60–1.22), -`findingsDerivationMs` (0.01–0.08 at 25), `legacyTopologyLayoutMs` (1.50–2.30 at -25; 19.4–26.0 at 100; 115.3–174.3 at 250), `productionBundleMs`. - -**10. Which numbers DO NOT prove production-host performance?** All of them: -the Docker inventory comes from a **deterministic local fixture daemon**, so -`dockerObservationMs` says nothing about a real Docker socket, host load, image -metadata or engine version; DockerMap, the API, the web build and Chromium all -ran **on one runner over loopback**, so no number is a network claim; the Compose -trees are **synthetic** (40 and 400 services); the fixtures are synthetic -topologies; and one runner class is pinned.

From ab75c6ee3cb76848be0801c1cd2564cabb6591bb Mon Sep 17 00:00:00 2001 From: Jonathan <64296013+Joncallim@users.noreply.github.com> Date: Wed, 23 Sep 2026 17:17:35 +0800 Subject: [PATCH 22/81] feat!: revise the time-to-answer methodology to a deterministic stage-5 phase sweep (#335) What (methodology revision 2, dockermap-v1/time-to-answer-methodology-2): - Stage 5 now DRIVES the publication phase instead of hoping for one. The poll interval is divided into 15 declared phases (one per recorded sample per run, each at the centre of its division), every run sweeps them ascending, and the harness controls the phase by choosing when it connects its observation stream relative to a predicted daemon publication. Each sample records its declared and observed phase, and asserts its own control: observed publication matches the prediction, observed latency lands on the declared phase within 60 ms, and the observation arrived through the real API poller path. - New validity guards (assertPollPhaseSweep): every declared phase represented at least twice, no uncontrolled phase, no non-poller observation, span >= half the interval, and the earliest declared phase at least half an interval slower than the latest. A narrow-band sweep is REJECTED - it is a RED test, not an aspiration. - Stage 5 reports a phase curve plus a PHASE-NORMALIZED p95 computed from the predeclared uniform grid, explicitly documented as a statement about the mechanism under uniformly sampled phase offsets - not an observed user-traffic distribution and not network latency. - Fixed warm-up protocol: five predeclared warm-up observations before the 15 measured samples, chosen from the round-3 windows (the second observation reached 2.15x the window median in 5/30 windows; index 5 onward stayed within 1.29x). Warm-ups are never dropped adaptively; a declared stationarity check (0.5x-1.5x band on the final two warm-ups against the measured median) INVALIDATES a window instead of trimming it. Every warm-up observation is retained. - Provenance is no longer compatibility: daemonBinarySha256, sourceRevision and harnessRevision are recorded but not required to match, so a candidate that changes crates/ (#336) is comparable; methodologyVersion, the toolchain, browser, fonts, fixture revision, build mode and polling configuration still must match. - The documented before-and-after daemon binary verification now exists: the digest is re-hashed after the run and the capture fails closed on a mismatch, with both digests recorded in the harness evidence. - The slow-Compose scenario premise is asserted (the project really declares its 400 services) instead of merely named, and the capture asserts the application page never contacted the daemon directly. - Docs corrected: stage 7 is a bounded render/presentation confirmation rather than "exactly one frame", the promotion section states the provenance/compatibility split with the exact field counts, the rejected-capture paths are right, and the stage-5 sections describe the sweep and the normalized figure. Why: round-3 review rejected baseline 3. Its stage-5 samples were a drift-locked sawtooth (reference-25 covered 6.0% of the 2000 ms interval with consecutive deltas under 19 ms) even though the harness slept a uniform random delay, because both the daemon refresh loop and the API poller are fixed 2 s loops; its single discarded warm-up still left a 2.15x-of-median observation inside the measured window; it gated promotion on a rebuilt binary digest; and it documented a post-run verification the code did not perform.

Cause: the predicted publication instant came from a single observed gap, which carries one cycle's refresh work plus the tracker's own start transient. Stage 5's deepest declared phases put the publication just after a poll tick, so a period error maps one-for-one into phase error, and the error was large enough to land the sample in a neighbouring phase bucket. Fix: the tracker now runs from daemon start (so the grid is known before the browser stages begin), requires four publications before the first sample is placed, and estimates the period by least-squares over the last eight publication instants instead of one gap. The control tolerance stays at 60 ms - below half the 133 ms grid step, so a sample cannot bucket into a neighbouring phase. --- tests/perf/capture.ts | 49 ++++++++++++++++++++++++++++++++----------- 1 file changed, 37 insertions(+), 12 deletions(-) diff --git a/tests/perf/capture.ts b/tests/perf/capture.ts index f416d403..11b50d42 100644 --- a/tests/perf/capture.ts +++ b/tests/perf/capture.ts @@ -542,7 +542,9 @@ async function startPublicationTracker(daemonPort: number, initialRevision: stri revision = next; publications.push(nowMs()); } - await sleep(2); + // 5 ms: the detection instant is the publication instant plus at most this, + // and the grid fit below averages that jitter across several publications. + await sleep(5); } })(); return { @@ -558,12 +560,24 @@ async function startPublicationTracker(daemonPort: number, initialRevision: stri } }, periodMs() { - const recent = publications.slice(-4); + const recent = publications.slice(-8); if (recent.length < 2) { throw new Error("stage 5 needs at least two observed publications before it can predict the next one"); } - const gaps = recent.slice(1).map((value, index) => value - recent[index]!); - return medianOf(gaps); + // Least-squares fit of publication index against instant.

Rather than claim a phase those cells never drove, the design now declares which fixtures are phase-controlled (POLL_PHASE_CONTROLLED_FIXTURES: the three reference fixtures and docker-topology-change) and which are free-running: - phase-controlled cells keep the declared grid, the per-sample control check and the full sweep guards (coverage, span, direction, poller path); - free-running cells record the phase they ACHIEVED (declared phase = the bucket the observation landed in), pass a separate guard that requires real poller observations and a minimum sample count, and derive NO phase-normalized figure; - the two guards refuse each other's samples, so a cell cannot claim a sweep it did not drive. --- .../performance/timeToAnswerPollPhase.test.ts | 48 +++++++++- .../lib/performance/timeToAnswerPollPhase.ts | 91 ++++++++++++++++++- tests/perf/capture.ts | 90 +++++++++++++----- tests/perf/summarize.ts | 9 +- 4 files changed, 211 insertions(+), 27 deletions(-) diff --git a/apps/web/src/lib/performance/timeToAnswerPollPhase.test.ts b/apps/web/src/lib/performance/timeToAnswerPollPhase.test.ts index 4d9bc668..4e2664d3 100644 --- a/apps/web/src/lib/performance/timeToAnswerPollPhase.test.ts +++ b/apps/web/src/lib/performance/timeToAnswerPollPhase.test.ts @@ -15,6 +15,7 @@ import { POLL_PHASE_CONTROL_TOLERANCE_MS, POLL_PHASE_DIVISIONS, POLL_PHASE_MIN_SAMPLES_PER_PHASE, + assertFreeRunningPhaseSamples, assertPollPhaseSweep, declaredPhaseForSample, intendedLatencyMs, @@ -54,7 +55,8 @@ function goodSweep(intervalMs = INTERVAL, errorMs = 4): PollPhaseSweep[] { phaseErrorMs: observed - intended, observedVia: "api-sse", observedRevision: `rev-${run}-${index}`, - previousRevision: `rev-${run}-${index}-prev` + previousRevision: `rev-${run}-${index}-prev`, + phaseControlled: true }); } } @@ -187,6 +189,50 @@ describe("stage-5 phase sweep validity", () => { }); }); +describe("stage-5 free-running cells", () => { + const freeRunning = (count: number, latencyMs: (index: number) => number): PollPhaseSweep[] => + Array.from({ length: count }, (_, index) => ({ + ...goodSweep()[0]!, + runIndex: 0, + sampleIndex: index % POLL_PHASE_DIVISIONS, + declaredPhaseMs: 0, + intendedLatencyMs: latencyMs(index), + observedLatencyMs: latencyMs(index), + phaseErrorMs: 0, + observedRevision: `free-${index}`, + previousRevision: `free-${index}-prev`, + phaseControlled: false + })); + + it("accepts real poller observations with the achieved phase recorded", () => { + const verdict = assertFreeRunningPhaseSamples(freeRunning(30, (index) => 100 + index * 50), 30); + expect(verdict.samples).toBe(30); + expect(verdict.spanMs).toBeGreaterThan(0); + expect(verdict.observedPhaseBucketsMs).toHaveLength(30); + }); + + it("REJECTS a free-running cell with too few samples", () => { + expect(() => assertFreeRunningPhaseSamples(freeRunning(5, () => 500), 10)).toThrow(/at least 10 samples/); + }); + + it("REJECTS a free-running sample that saw no new revision or a non-poller path", () => { + const idle = freeRunning(30, () => 500).map((sample, index) => + index === 3 ? { ...sample, observedRevision: sample.previousRevision } : sample + ); + expect(() => assertFreeRunningPhaseSamples(idle, 10)).toThrow(/no new revision/); + const shortcut = freeRunning(30, () => 500).map((sample, index) => + index === 7 ? { ...sample, observedVia: "daemon-direct" } : sample + ); + expect(() => assertFreeRunningPhaseSamples(shortcut, 10)).toThrow(/real API poller path/); + }); + + it("REJECTS a declared sweep over free-running samples", () => { + // The two guards must not be interchangeable: a cell whose phase the harness did + // not drive cannot claim the sweep's coverage. + expect(() => assertPollPhaseSweep(freeRunning(30, () => 500), INTERVAL)).toThrow(/did not drive/); + }); +}); + describe("stage-5 phase-normalized summary", () => { it("reports a median per declared phase and normalises over the uniform grid", () => { const grid = pollPhaseGridMs(INTERVAL); diff --git a/apps/web/src/lib/performance/timeToAnswerPollPhase.ts b/apps/web/src/lib/performance/timeToAnswerPollPhase.ts index d3062b80..ac2fd0f3 100644 --- a/apps/web/src/lib/performance/timeToAnswerPollPhase.ts +++ b/apps/web/src/lib/performance/timeToAnswerPollPhase.ts @@ -54,9 +54,32 @@ export const POLL_PHASE_CONTROL_TOLERANCE_MS = 60; export const POLL_PHASE_MIN_SPAN_SHARE = 0.5; export const POLL_PHASE_MIN_DIRECTION_SHARE = 0.5; -/** Every declared phase must appear at least this many times in a cell. */ +/** Every declared phase must appear at least this many times in a controlled cell. */ export const POLL_PHASE_MIN_SAMPLES_PER_PHASE = 2; +/** + * Cells whose publication the harness can actually trigger, and which therefore get + * the declared phase sweep. + * + * The two provider-state fixtures are NOT here on purpose.

Cause: the API emits the current revision immediately on connect, and previousRevision came from the tracker's last poll, which can be up to 10 ms stale. A revision published in that window made the very first frame look like a new publication, so the sample was attributed to the PREVIOUS cycle's boundary. Fix, in two parts: the pre-sample revision is now read fresh from the daemon health endpoint right before the stream opens, and a sample only accepts a frame that could be its own observation - for a controlled sample, at or after the predicted cycle (safe because its poll tick cannot land earlier while the connect frame precedes it by the declared phase); for a free-running sample, a margin after the connect.

The publication prediction was accurate (33 ms), and the residual is the observation tick itself - the API's setInterval drifts under load, measured +52 ms at 250 containers. A 15-division grid (133 ms step) cannot survive that: the tolerance has to stay below half a step or neighbouring phases blur, and 60 ms was not enough. The grid is now 10 declared divisions (200 ms step, latencies 100-1900 ms, still 90% of the interval) with a 90 ms declared tolerance - below half a step, above the measured drift. Fifteen recorded samples per run now walk the whole grid and repeat its opening five phases, so every declared phase carries at least three samples across the three runs; a test asserts that coverage. --- .../performance/timeToAnswerPollPhase.test.ts | 23 ++++++++--- .../lib/performance/timeToAnswerPollPhase.ts | 39 +++++++++++++------ 2 files changed, 45 insertions(+), 17 deletions(-) diff --git a/apps/web/src/lib/performance/timeToAnswerPollPhase.test.ts b/apps/web/src/lib/performance/timeToAnswerPollPhase.test.ts index 4e2664d3..34a561ca 100644 --- a/apps/web/src/lib/performance/timeToAnswerPollPhase.test.ts +++ b/apps/web/src/lib/performance/timeToAnswerPollPhase.test.ts @@ -67,7 +67,6 @@ describe("stage-5 declared phase grid", () => { it("divides the poll interval into the declared number of phases", () => { const grid = pollPhaseGridMs(INTERVAL); expect(grid).toHaveLength(POLL_PHASE_DIVISIONS); - expect(grid).toHaveLength(TIME_TO_ANSWER_WARMED_SAMPLES); expect([...grid].sort((left, right) => left - right)).toEqual(grid); expect(new Set(grid).size).toBe(grid.length); // Every phase sits strictly inside the interval: a publication landing exactly @@ -88,15 +87,29 @@ describe("stage-5 declared phase grid", () => { expect(latencies[latencies.length - 1]!).toBeGreaterThan(0); }); - it("assigns one declared phase per sample, identical across runs", () => { - for (let index = 0; index < POLL_PHASE_DIVISIONS; index += 1) { + it("walks the declared grid once per run and repeats it, identically across runs", () => { + const grid = pollPhaseGridMs(INTERVAL); + for (let index = 0; index < TIME_TO_ANSWER_WARMED_SAMPLES; index += 1) { const runZero = declaredPhaseForSample(0, index, INTERVAL); expect(declaredPhaseForSample(1, index, INTERVAL)).toBe(runZero); expect(declaredPhaseForSample(2, index, INTERVAL)).toBe(runZero); - expect(runZero).toBe(pollPhaseGridMs(INTERVAL)[index]); + // Fifteen samples against ten divisions: each run covers the whole grid and then + // repeats its opening phases, so no phase is left with a single sample. + expect(runZero).toBe(grid[index % POLL_PHASE_DIVISIONS]); } - expect(() => declaredPhaseForSample(0, POLL_PHASE_DIVISIONS, INTERVAL)).toThrow(); + const coverage = new Map(); + for (let run = 0; run < 3; run += 1) { + for (let index = 0; index < TIME_TO_ANSWER_WARMED_SAMPLES; index += 1) { + const phase = declaredPhaseForSample(run, index, INTERVAL); + coverage.set(phase, (coverage.get(phase) ?? 0) + 1); + } + } + expect(coverage.size).toBe(POLL_PHASE_DIVISIONS); + expect(Math.min(...coverage.values())).toBeGreaterThanOrEqual( + POLL_PHASE_MIN_SAMPLES_PER_PHASE + ); expect(() => declaredPhaseForSample(0, -1, INTERVAL)).toThrow(); + expect(() => declaredPhaseForSample(0, 1.5, INTERVAL)).toThrow(); }); it("buckets an observed latency to the nearest declared latency", () => { diff --git a/apps/web/src/lib/performance/timeToAnswerPollPhase.ts b/apps/web/src/lib/performance/timeToAnswerPollPhase.ts index ac2fd0f3..530a56e3 100644 --- a/apps/web/src/lib/performance/timeToAnswerPollPhase.ts +++ b/apps/web/src/lib/performance/timeToAnswerPollPhase.ts @@ -35,7 +35,14 @@ */ /** Equal parts the poll interval is divided into; one declared phase per sample per run. */ -export const POLL_PHASE_DIVISIONS = 15; +/** + * Declared divisions of the poll interval.

The repeated 21-run lifecycle regression demonstrates fresh control state and deterministic closure. --- tests/perf/browserLifecycle.mjs | 16 ++++++++ tests/perf/browserLifecycle.test.mjs | 44 ++++++++++++++++++++++ tests/perf/capture.ts | 56 +++++++++++++++++----------- 3 files changed, 94 insertions(+), 22 deletions(-) create mode 100644 tests/perf/browserLifecycle.mjs create mode 100644 tests/perf/browserLifecycle.test.mjs diff --git a/tests/perf/browserLifecycle.mjs b/tests/perf/browserLifecycle.mjs new file mode 100644 index 00000000..5b9d4e56 --- /dev/null +++ b/tests/perf/browserLifecycle.mjs @@ -0,0 +1,16 @@ +/** + * Own the browser lifetime for one controlled capture run. + * + * A capture run may exercise several fixtures, but it must not inherit browser + * pages, connections, caches, or renderer state from an earlier run. + */ +export async function withFreshBrowserRuns({ runs, launch, run }) { + for (let runIndex = 0; runIndex < runs; runIndex += 1) { + const browser = await launch(); + try { + await run(browser, runIndex); + } finally { + await browser.close(); + } + } +} diff --git a/tests/perf/browserLifecycle.test.mjs b/tests/perf/browserLifecycle.test.mjs new file mode 100644 index 00000000..909adc83 --- /dev/null +++ b/tests/perf/browserLifecycle.test.mjs @@ -0,0 +1,44 @@ +import assert from "node:assert/strict"; +import test from "node:test"; +import { withFreshBrowserRuns } from "./browserLifecycle.mjs"; + +test("repeated control-shaped runs start with a fresh browser and close it after every run", async () => { + const browsers = []; + const rendered = []; + await withFreshBrowserRuns({ + runs: 21, + launch: async () => { + const browser = { pageValue: "0", closed: false, async close() { this.closed = true; } }; + browsers.push(browser); + return browser; + }, + run: async (browser, runIndex) => { + // This is the stale-Home failure shape: a reused page would retain the + // previous control's value instead of beginning from the fixture baseline. + assert.equal(browser.pageValue, "0"); + browser.pageValue = String(runIndex + 1); + rendered.push(browser.pageValue); + } + }); + assert.deepEqual(rendered, Array.from({ length: 21 }, (_, index) => String(index + 1))); + assert.equal(new Set(browsers).size, 21); + assert.ok(browsers.every((browser) => browser.closed)); +}); + +test("a failed run still closes its browser before the next clean run", async () => { + const browsers = []; + await assert.rejects( + withFreshBrowserRuns({ + runs: 2, + launch: async () => { + const browser = { closed: false, async close() { this.closed = true; } }; + browsers.push(browser); + return browser; + }, + run: async () => { throw new Error("control failed"); } + }), + /control failed/ + ); + assert.equal(browsers.length, 1); + assert.equal(browsers[0].closed, true); +}); diff --git a/tests/perf/capture.ts b/tests/perf/capture.ts index 4a15b328..16eac911 100644 --- a/tests/perf/capture.ts +++ b/tests/perf/capture.ts @@ -68,6 +68,7 @@ import { } from "../../apps/web/src/lib/performance/timeToAnswerPollPhase"; import { FIXTURE_REVISION, SLOW_COMPOSE_SERVICES, buildSlowComposeProject, expectedExitedCount } from "./dockerFixtureTopology.mjs"; import { reservePort, startStaticServer } from "./staticServer.mjs"; +import { withFreshBrowserRuns } from "./browserLifecycle.mjs"; const REPO_ROOT = resolve(fileURLToPath(new URL("../..", import.meta.url))); const sleep = (ms: number) => new Promise((done) => setTimeout(done, ms)); @@ -364,7 +365,7 @@ function stopOwned(child: { pid?: number; exitCode: number | null; signalCode?: } async function fetchJson(url: string, timeoutMs = 5_000): Promise { - const controller = new AbortController(); + const controller = new AbortController(); const timer = setTimeout(() => controller.abort(), timeoutMs); try { const response = await fetch(url, { signal: controller.signal }); @@ -772,7 +773,11 @@ async function observeStageFiveSample(input: { headers: { accept: "text/event-stream", origin: input.webOrigin }, signal: controller.signal }); - const reader = response.body!.getReader(); + if (!response.ok || !response.body) { + controller.abort(); + throw new Error(`stage 5 observation stream did not open (HTTP ${response.status})`); + } + const reader = response.body.getReader(); const decoder = new TextDecoder(); const reading = (async () => { let buffer = ""; @@ -807,7 +812,8 @@ async function observeStageFiveSample(input: { } })(); - await input.onConnected({ + try { + await input.onConnected({ declaredPhaseMs, intendedLatencyMs: intended, predictedPublicationAtMs: predicted, @@ -817,9 +823,7 @@ async function observeStageFiveSample(input: { // The publication instant is resolved by the tracker's own health polling, which // runs continuously and independently of the API stream. const deadline = Date.now() + (input.timeoutMs ??
