Implementation record

Starting state and ownership

On 4 October 2026 the supplied workspace contained only the master brief. The initial implementation cloned the referenced public repository at 2420ff4c2a88b1fa4a19e413cb0752e271480081 on main, preserving the brief. Existing documentation validation passed before changes. That initial monorepo phase performed no remote publication; its local check records are retained under migration-evidence/monorepo-audit/.

The owner subsequently requested a standalone private documentation repository, devSatym/resilience-gate-docs, without pushing the existing platform repository. Website code, canonical articles, diagrams, and engineering records are transferred separately from the public upstream implementation. The supplied brief is preserved here as PROJECT-BRIEF.md. The ignored upstream checkout at .source/resilience-gate retains the reviewed pin; application, infrastructure, platform tests, and platform release workflows are not tracked in the new repository.

Four real concurrent workers covered the requested roles with bounded parallelism. The lead owns site configuration, lockfile, registry, preparation, UI, diagrams, engineering artifacts, CI and integrated acceptance. Application worker owns runtime/request/health/failure pages and application design. Delivery worker owns artifact/promotion/gate/measurement pages and delivery/gate/integrated designs. Operations/evidence worker owns runbooks, evidence cases, schema references and source coverage. Independent review follows writing with a worker reassigned outside its own page ownership.

Initial implementation stages

Stage	Result and dependency
Source baseline	Public HEAD and clean upstream state recorded; pre-existing screenshot/diagram rules verified
Schema and route architecture	Six sections; stable explicit route registry; source-relative canonical links
Publishing boundary	AST transform, input validation, original hash checks and optimized derivatives
UI and explanatory diagrams	Custom light/dark Starlight overrides; native gallery dialog; ten accessible source-derived SVGs
Full editorial integration	Parallel teaching narratives, operator pages, platform designs and exact evidence distinctions
CI and local checks	Dedicated static documentation workflow; credential-free type/unit/build validation
Browser and source review	Production crawl, search, responsive states, accessibility/performance and independent critique
Final reports and rerun	Reports updated from measured artifacts; final build/check includes reports
Publication state	Initial deployment configuration; remote publication not performed

Prior repository-separation stages

Stage	Responsibility and verification record
Repository separation	Own website authoring sources; retain upstream implementation/evidence only in the ignored pinned checkout
Source bootstrap and resolution	npm ci then npm run source:prepare; distinguish logical source paths, input origins, documentation HEAD, and reviewed upstream revision
Route and base preservation	Preserved the initial 56 mapped routes at the then-default /resilience-gate-docs/ base, with separate root-base checks
Initial CI boundary	Read-only PR/main builds with an explicit Pages deployment gate; superseded by validation-only CI in the Cloudflare migration
New local acceptance	Actual commands, outcomes, counts, and input identities belong to docs/website/audit/migration/local-checks.json
Private repository transfer	Creation, privacy verification, commit, and push outcome belong to docs/website/audit/migration/repository-transfer.json
Website publication	Not performed during that phase; repository transfer remained separate from hosting

The retained machine receipts identify the completed checks and transfer state of this phase. Prior monorepo unit, browser, accessibility, and performance measurements did not substitute for repository-separation verification, and neither set substitutes for the new Cloudflare checks.

Current Git-integrated Pages migration

The owner subsequently required the pinned GCP Security Handbook deployment guide and update guide. This supersedes the Workers selection in decision 006, which remains historical.

Stage	Responsibility and receipt boundary
Static target	Base /; initial stable origin is the confirmed assigned Pages hostname, promoted to https://resilience-gate.devsatym.xyz only after normal custom-host TLS works
Native Git configuration	Private devSatym/resilience-gate-docs, branch main, root site, native command DOCS_SITE=<reviewed stable origin> npm run build:cloudflare, output dist, Node 22.20.0; no Direct Upload, SSR, Functions, or storage
Documentation	Current maintenance/runbook guidance and decision 007; decision 006, original brief, and earlier audit receipts remain historical
Local validation	Static artifact checks, Astro and Wrangler Pages browser checks, rendered audit, and a local plan without upload
Account and Git ownership	Existing Pages OAuth and the selected-repository GitHub App grant are separate prerequisites; inspect account/project/source/main before mutation
Initial publication	Pause production/previews during creation, confirm assigned hostname, configure explicit DOCS_SITE, request native Git build, and verify the served artifact
Custom-host handoff	Register Pages domain first; owner adds only new CNAME resilience-gate → resilience-gate-docs.pages.dev at existing Spaceship DNS; no nameserver, existing record, or paid change
Continuous editing	Configuration enables native branch previews while production automatic builds remain paused; enable main production after initial verification; GitHub validation does not gate Pages automatically
Actual results	New campaign docs/website/audit/cloudflare-pages/; actual deployment Git identity and hosted observations are recorded independently from this configuration checkpoint

The valid Pages OAuth observation supports the selected API workflow; the prior Workers zone/Billing Read failures are not prerequisites for this external-DNS Pages subdomain. No handbook pass or old test count substitutes for this site’s new verification. The publication runbook records the staged commands and owner actions. Earlier Workers evidence remains unchanged under docs/website/audit/cloudflare/.

Decisions and corrections

The stack was fixed by the brief; official APIs and npm peer/runtime constraints determined compatible locked versions during initial implementation. Website content remains canonical in the standalone documentation repository, with an explicit adapter rather than a wholesale platform copy. Native SVGs keep diagrams local and script-free. Existing platform screenshots remain unchanged in the pinned upstream source; website audit images live separately. Native Git-integrated Pages now serves the root base, first at the confirmed Pages origin and later at the verified custom origin, with no application runtime added. Private repository source does not imply a private website.

Source review distinguished initial Redis readiness from steady-state fallback, paid preflight from continuous signer-fault traffic, workflow waits from scorer windows, deliberate zero-fallback queries from missing evidence, and scoring from EXIT cleanup. These findings changed the explanation rather than underlying code. Website findings and reruns are recorded in the audit; measured delivery details are in the final report.
