…amples#363) (aws-samples#364) * docs(design): add CI build performance design doc (aws-samples#363) Records how the build workflow's cost is distributed (//cdk:test was the ~91% long pole), why it was expensive (redundant type-check, fixed in aws-samples#357 / PR aws-samples#359), and the remaining levers (shard, coverage-gate, runner size, path-filter) with sequence and implementer notes — including the merge-queue required-check constraints that shape #2 and aws-samples#5. Companion to umbrella issue aws-samples#363; keeps the optimization roadmap as a durable, reviewable design artifact. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(design): add sharding design for CDK suite (aws-samples#363) Expands the CI build-performance doc with a full design for item #2 (shard the CDK suite): the jest --shard mechanism, a shards-vs-wall-time table showing fixed overhead dominates past ~4 shards, the fan-out + aggregate-gate pattern needed to keep `build` a single required context on merge_group, cross-shard coverage merge before threshold enforcement, and open questions (synth placement, deploy artifact, shard balance). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(design): correct CI build-performance figures + shard/priority analysis per review (aws-samples#363) Remediates @theagenticguy's CHANGES_REQUESTED (7 inline comments) with measured merge_group data from runs 30412723686 (Build 171s, //cdk:test 125.08s / 136 suites), 30409171662 (186s), 30400147506 (148s): 1. Ledger split so aws-samples#359 (type-check removal) and aws-samples#371 (Lambda-bundling disable) each get credit; restated current baseline (build ~148-186s, //cdk:test ~125s) with the run IDs it came from — not the stale ~346s/~298s post-#1 column. 2. 'Paid for twice' scoped: src/ went twice->once; test/ went once->zero (tsc only includes src/**); eslint tsconfig.dev.json backstops narrowly; noted deferred tsc --noEmit -p tsconfig.dev.json lever. 3. Idle-window claim corrected: synth ends +142s vs //cdk:test +171s -> ~29s idle, not ~200s; named //cdk:synth:quiet as the next binding constraint for sharding. 4. fixed_overhead restated as 120-220s measured from job start (not ~95s from install); added cache-miss finding (node_modules/venv/jest miss on every merge_group run) as new recommendation aws-samples#6. 5. Shard math recomputed with measured inputs -> 4-way lands at/above whole build; #2 demoted to deferred (revisit trigger //cdk:test > ~250s); sequencing re-ranked to elevate cache hit-rate (aws-samples#6), runner size (#4), path filters (aws-samples#5) over sharding. 6. Aggregate-job if: fixed to GitHub's documented pattern (job if: always(), gate moved into a step keying on failure||cancelled); explained why bare contains() never runs. 7. Check-run names corrected to build (agentcore) (build.yml compute_type matrix + ruleset 14980587, confirmed PR aws-samples#672); shard dim yields build (agentcore, N); flagged as a REQUIRED-CONTEXT change, not workflow-only. Rebased onto latest origin/main; regenerated Starlight mirror via docs:sync. Relates to aws-samples#363 Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> * docs(design): correct cache/disk-overhead analysis + add nav entries per re-review (aws-samples#363) Re-review round 2 (theagenticguy) surfaced 3 new inline findings plus a dropped nav finding. Corrections, cross-checked against per-step job timings: - Cache hits do not save time. Comparing a miss merge_group run (30412723686) vs a hitting pull_request run (30419878840) with the identical yarn.lock hash: Cache * restore 1s->9s, yarn 48.35s->55.09s, Install dependencies 56s->60s. The hit path is net SLOWER because mise.toml [tasks.install] runs yarn install --check-files, which re-verifies every restored file; uv sync installs 127 pkgs in 121ms so a venv cache cannot pay for itself. Rec aws-samples#6 reframed as a --check-files investigation and demoted in sequencing; no more cache-win claims. - Free Disk Space is the dominant addressable overhead, not cache misses. Per-step timings (gh api .../jobs/<id> .steps[]): run 30412723686 (job 90452344735) 148s/220s = 67%; run 30419878840 (job 90474296240) 97s/179s = 54%; run 30418865914 (job 90471207016) 75s/158s = 47%. Added as new ledger item aws-samples#7 ahead of aws-samples#6; feeds the shard math. - fixed_overhead breakdown named inline: of 120-220s, Free Disk Space is 75-148s and install is a cache-independent ~56-60s. ~250s shard trigger is now conditional on overhead staying 120-220s. - Nav fix: astro.config.mjs Architecture sidebar is an explicit list, so added slug entries architecture/ci-build-performance and architecture/bedrock-cost-attribution (both were missing from nav).
