Update work mirror MirroredAt to 7c86a22

[The-Running-Dev]

What changed, and why. Trailing sync from the prior reconcile commit (#373, 7c86a22):
bumps the MirroredAt stamp on all 48 design/state/work/*.md files to that SHA. No content
changes — the reconcile itself was correct, this commit just wasn't pushed before the session
that made it ended.

• Validate Markdown links, terminology, and generated files — ./build/Test-Documentation.ps1 — "Human-documentation drift check passed across 18 generated engine page(s), compatibility pointers, and the guide. Documentation checks passed across 173 Markdown file(s)."

• Test the host — dotnet test src/host/SubZeroDev.GameEngine.Host.Tests — all projects up-to-date for restore — Passed: 12, Failed: 0, Skipped: 0, Total: 12, Duration 351 ms

Ran and failed:

• Run Pester tests — Invoke-Pester -Path tools -Output Detailed -PassThru — Tests Passed: 243, Failed: 10, Skipped: 0, NotRun: 0; plus 1 BeforeAll/AfterAll block failure ("CI workflow: the Run Pester tests step is authenticated (Reconcile the blog repository's guidelines into CLAUDE.md #79)" — ParameterBindingValidationException: Cannot bind argument to parameter 'LiteralPath' because it is null, at Test-CIWorkflow.Tests.ps1:26). Identical count and identical failure set to the run recorded against this same branch's predecessor state earlier today (verify-report.json history, commit 8128a0f), which already traced these as pre-existing design-state drift, not caused by this branch's design/state/work/ MirroredAt-only edits: (1) "S4.6: unit/command/track and unit/document/agents-md exist and their closures are complete" — Expected $true, got $false. (2) "the Run Pester tests step carries a GH_TOKEN env, the same as Check the design state against the tree" — pre-existing, also fails on main. (3) "this repository's own table and its own enumeration agree" — Expected $null or empty, got ContractListUnreadable/GlobTableNotFound: design/20-contract.md. (4) "S12.5: the check exits 0 against this repository, and names the largest closure and its size" — Expected 0, got 2; dozens of [UnrecordedArtifact]/[LogEntryUnrecorded] entries, [RegionMalformed] in five design/ files, [ContractListUnreadable], [ProjectorFailed] exited 1, [TrackerUnavailable] for all 48 mirrored issues. (5) "S7.9: the projector runs against this repository and ProjectionStale does not fire" — ProjectorFailed/exited 1. (6) "S16.1/S16.2: one Contract record per Public-surface entry" — Expected 9, got 0. (7) "S16.5: design/state-index.md's consumers region lists real consumers" — Cannot find path design/state-index.md. (8) "S17.2: every invariant row sits inside the single invariants region" — Expected actual value greater than -1, got -1. (9) "S18.6: EnforcementUnevidenced rejects this repository's own superseded decision" — Cannot find path design/state/decisions/2026-08-03-ticking-checkbox-is-the-users.md. (10) "S7.2: -DryRun against the real repository writes nothing" — Expected 0, got 7 refusals (same set as TEMPORARY — W0 red-path proof (do not merge) #4). This branch does not touch design/30-slices.md, design/90-decisions.md, design/20-contract.md, or any tools/.ps1 — only design/state/work/.md MirroredAt stamps — so it cannot be the cause of this pre-existing drift; this command does not fix it. Filed as Test-DesignState.ps1: 9 findings against this repository's own tree (ContractListUnreadable, ProjectorFailed, TrackerUnavailable, etc.) #375.

Did not run:

• Build documentation — Runs inside the ghcr.io/the-running-dev/docs-template container image via docs.ps1. docs.ps1 (the local wrapper) is absent from this checkout — CLAUDE.md states it is installer-generated (Invoke-SetupDocs), not committed. Docker itself is running locally, but the wrapper script needed to invoke the containerized build is missing, so this was not attempted; the corresponding CI check ("Verify Documentation Build") on the pull request is where the answer will come from.
• Merge landing page into documentation build — npm --prefix site run merge needs a completed docs build in artifacts/docs, which the "Build documentation" gate above did not produce (docs-template container image not available locally without the docs.ps1 wrapper).
• Positive route and probe smoke — Requires building the host Docker image, which restores SubZeroDev.Platform.Hosting from a private GitHub Packages NuGet feed inside the build via a docker/build-push-action secret (nuget_github_token). REGISTRY_TOKEN is not present in this local environment, so the image build step itself cannot be reproduced locally even though Docker is running; the corresponding CI check ("Build, run, and smoke the image") on the pull request is where the answer will come from.
• Negative fixture -- corrupted artifact must fail to start — Same dependency as "Positive route and probe smoke": requires the built host image, blocked on the missing REGISTRY_TOKEN for the private NuGet feed restore.
