test(lib): add hydrate.test.ts coverage (7 cases) — exponential backoff retry

Add test coverage for canvas store hydration with exponential backoff:
- Successful first-attempt hydration (stores + viewport)
- Non-fatal viewport fetch failure (succeeds without viewport)
- MAX_RETRIES=3 exhausts all attempts on persistent failure
- onRetrying callback fires before each retry
- Second-attempt success short-circuits remaining retries
- Exponential backoff: 1000 → 2000 → 4000ms between retries

Uses vi.hoisted() to share mock refs across vi.mock factories
(vitest hoists factories before module-level code).

-"""lint-pre-flip-continue-on-error — block a PR that flips a job from
-``continue-on-error: true`` to ``continue-on-error: false`` (or removes
-the key while the base had it ``true``) without proof that the job's
-recent runs on the target branch are actually green.
-
-Empirical class — PR #656 / mc#664:
-  PR #656 (RFC internal#219 Phase 4) flipped 5 ``platform-build``-class
-  jobs ``continue-on-error: true → false`` on the basis of a
-  "verified green on main via combined-status check". But that "green"
-  was the LIE produced by the prior ``continue-on-error: true``:
-  Gitea Quirk #10 (internal#342 + dup #287) — when a step inside a
-  job marked ``continue-on-error: true`` fails, the job-level status
-  is still rolled up as ``success``. So the precondition the PR
-  claimed to verify was structurally fooled by the bug being
-  flipped.
-
-  mc#664 then captured the surfaced defects (2 unrelated, mutually-
-  masked regressions):
-
-    Class 1: sqlmock helper drift since 2f36bb9a (24 days old)
-    Class 2: OFFSEC-001 contract collision since 7d1a189f (1 day old)
-
-  Codified 04:35Z as hongming-pc2 charter §SOP-N rule (e)
-  "run-log-grep-before-flip": pull the actual run log + grep for
-  ``--- FAIL`` / ``FAIL\\s`` BEFORE flipping; don't trust the masked
-  combined-status.
-
-This script structurally enforces that rule at PR time.
-
-How it works (one PR tick):
-  1. Parse the diff: compare ``.gitea/workflows/*.yml`` at PR base
-     vs PR head. For each file present in both, parse the YAML AST
-     and walk ``jobs.<key>.continue-on-error`` on each side. A
-     "flip" is base ∈ {true} AND head ∈ {false, None/absent}. We
-     coerce truthy/falsy per YAML semantics (PyYAML normalizes
-     ``true``/``True``/``yes`` to ``True``).
-  2. For each flipped job, derive its commit-status context name as
-     ``"{workflow.name} / {job.name or job.key} (push)"`` — that's
-     how Gitea Actions emits the context for runs on
-     ``main``/``staging`` (push event, see also expected_context()
-     in ci-required-drift.py).
-  3. Pull the last N commits of the target branch (PR base), fetch
-     combined commit-status per commit, scan ``statuses[]`` for
-     contexts matching ANY of the flipped jobs. For each match,
-     fetch the actual run log via the web-UI route
-     ``{server_url}/{repo}/actions/runs/{run_id}/jobs/{job_idx}/logs``
-     (per memory ``reference_gitea_actions_log_fetch`` — Gitea 1.22.6
-     lacks REST ``/actions/runs/*`` endpoints; the web-UI route is the
-     only working path; see ``reference_gitea_1_22_6_lacks_rest_rerun_endpoints``).
-  4. Grep each log for the Go-test failure markers ``--- FAIL`` /
-     ``FAIL\\s+<package>`` AND the bash-step error sentinel
-     ``::error::``. If ANY recent log shows any of these AND the
-     status itself reads ``success``, the job was masked. ``::error::``
-     the flip with the offending test name + offending run URL +
-     the regression commit (HEAD of the run).
-  5. Exit 1 if any flips have at least one masked run; exit 0
-     otherwise.
-
-Halt-on-noise contract:
-  - If a recent log fetch 404s (already-pruned-via-act_runner-gc,
-     transient gitea-web outage): emit ``::warning::`` and treat the
-     run as "log unavailable" — does NOT block the flip; logged so
-     a curious reviewer can re-run.
-  - If a flipped job has ZERO recent runs on the target branch (newly
-     added workflow): emit ``::warning::`` "no run history to verify"
-     and allow the flip. This is the only way a NEW workflow can ever
-     ship with ``continue-on-error: false``; otherwise we'd have a
-     chicken-and-egg.
-
-Behavior-based AST gate per ``feedback_behavior_based_ast_gates``:
-  - YAML parsed via PyYAML safe_load on BOTH sides of the diff
-  - No grep-by-line — formatting changes (comment churn, key order)
-    don't false-positive a flip
-  - Job-key match — so a rename ``platform-build → core-be-build``
-    appears as a DELETE + an ADD, not a flip (the delete side has no
-    new value to compare against; the add side has no base side).
-
-Run locally (works against this repo, requires PyYAML + Gitea token
-that can read combined-commit-status):
-
-    GITEA_TOKEN=... GITEA_HOST=git.moleculesai.app \\
-      REPO=molecule-ai/molecule-core BASE_REF=main \\
-      BASE_SHA=$(git rev-parse origin/main) \\
-      HEAD_SHA=$(git rev-parse HEAD) \\

-# Pre-merge gate: blocks PRs that flip `continue-on-error: true → false`
-# on any job in `.gitea/workflows/*.yml` WITHOUT proof that the affected
-# job's recent runs on the target branch (PR base) are actually green.
-#
-# Empirical class: PR #656 / mc#664. PR #656 (RFC internal#219 Phase 4)
-# flipped 5 platform-build-class jobs `continue-on-error: true → false`
-# on the basis of a "verified green on main via combined-status check".
-# But that "green" was the LIE the prior `continue-on-error: true`
-# produced: Gitea Quirk #10 (internal#342 + dup #287) — a failed step
-# inside a `continue-on-error: true` job rolls up to a `success`
-# job-level status. The precondition the PR claimed to verify was
-# structurally fooled by the bug being flipped.
-#
-# mc#664 captured the surfaced defects (2 mutually-masked regressions):
-#   - Class 1: sqlmock helper drift since 2f36bb9a (24 days old)
-#   - Class 2: OFFSEC-001 contract collision since 7d1a189f (1 day old)
-#
-# Codified 04:35Z as hongming-pc2 charter §SOP-N rule (e)
-# "run-log-grep-before-flip" — now structurally enforced here at PR
-# time, ahead of merge.
-#
-# How the gate works:
-#   1. Read every `.gitea/workflows/*.yml` at the PR base SHA AND at
-#      the PR head SHA via `git show <sha>:<path>` (no checkout
-#      needed).
-#   2. Parse both sides via PyYAML AST (NOT grep — per
-#      `feedback_behavior_based_ast_gates`). Walk `jobs.<key>.
-#      continue-on-error` on each side. A flip is base=true,
-#      head=false.
-#   3. For each flipped job, render the commit-status context as
-#      `"{workflow.name} / {job.name or job.key} (push)"` — that's
-#      how Gitea Actions emits the per-context status on `main`/
-#      `staging` runs.
-#   4. Pull last 5 commits on the PR base branch, fetch combined
-#      commit-status per commit, scan for the target context. For
-#      each match, fetch the run log via the web-UI route
-#      `{server_url}/{repo}/actions/runs/{run_id}/jobs/{job_idx}/logs`
-#      (per `reference_gitea_actions_log_fetch` —
-#      Gitea 1.22.6 lacks REST `/actions/runs/*`; web-UI is the

-# scripts/promote-tenant-image.sh
-#
-# Codified ECR :<source-tag> → :<dest-tag> promote + tenant fleet redeploy.
-# Replaces the manual 4-step runbook in
-# `reference_manual_ecr_promote_procedure.md` (memory) and closes
-# molecule-ai/molecule-core#660.
-#
-# Default flow (no flags):
-#   1. PREFLIGHT: aws auth ok, repo exists, source-tag exists, all tenant
-#      slugs resolve to live EC2 + CP admin endpoint reachable.
-#   2. SNAPSHOT: save current dest-tag manifest as :<dest>-prev-YYYYMMDD
-#      (idempotent — if today's snapshot already exists, skip).
-#   3. PROMOTE: copy <source-tag> manifest → <dest-tag>. Records the new
-#      digest so step 5 can verify.
-#   4. REDEPLOY: per-tenant POST /cp/admin/tenants/<slug>/redeploy. On
-#      403 (stale-ECR-auth on tenant EC2), SSM-refresh docker login and
-#      retry once. Hard-fail if both attempts fail.
-#   5. VERIFY: per-tenant curl /buildinfo + /health. /buildinfo.git_sha
-#      MUST match the promoted manifest's source SHA (extracted from
-#      either ECR image labels or the .git_sha tag annotation).
-#
-# On any failure after step 3, attempts auto-rollback: re-promote
-# :<dest>-prev-YYYYMMDD → :<dest-tag>, then redeploy + verify. Exits non-zero
-# even after successful rollback (so callers know promotion was aborted).
-#
-# Usage:
-#   scripts/promote-tenant-image.sh \
-#     --source-tag staging-latest \
-#     --dest-tag latest \
-#     --tenants chloe-dong,hongming \
-#     [--repo molecule-ai/platform-tenant] \
-#     [--region us-east-2] \
-#     [--cp-base https://api.moleculesai.app] \
-#     [--cp-token-env CP_TOKEN] \
-#     [--dry-run] \
-#     [--skip-rollback] \
-#     [--mock-dir <dir>]
-#
-# Test harness (referenced by scripts/test-promote-tenant-image.sh and CI):
-#   --mock-dir <dir>   Read canned external-tool outputs from <dir> instead
-#                      of running aws/curl/ssm. Each function reads from a
-#                      filename matching the function name. Stdout of the
-#                      mock files is returned verbatim; a `.rc` sidecar file
-#                      controls exit code. Mock dir is the only way to
-#                      exercise the failure branches in unit tests.
-#
-# Exit codes:
-#   0   promote + redeploy + verify all green
-#   1   preflight failed (no mutations performed)
-#   2   promote step failed (no rollback needed — snapshot intact)
-#   3   redeploy/verify failed; rollback succeeded
-#   4   redeploy/verify failed; rollback ALSO failed (paging-level)
-#   64  argument/usage error
