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_bp_context_emit_match — Tier 2f per internal#350.
-
-Rule
-----
-For a given protected branch, every context in
-`branch_protections/<branch>.status_check_contexts` MUST be emitted
-by at least one workflow in `.gitea/workflows/*.yml`. Two contexts
-match when:
-
-  1. The workflow's `name:` equals the context's workflow-part (the
-     prefix before ` / `).
-  2. Some job in that workflow has a `name:` (or default-fallback
-     job-key) equal to the context's job-part (between ` / ` and
-     ` (`).
-  3. The workflow's `on:` block includes the context's event-part
-     (in parens at the end), with Gitea's event-name mapping:
-        - `pull_request` and `pull_request_target` BOTH emit
-          `(pull_request)` contexts (verified empirically on
-          molecule-core/main).
-        - `push` emits `(push)`.
-
-A BP context with no emitter blocks merges forever — Gitea treats
-absent-as-`pending`, NOT absent-as-`skipped`-as-`success`. This is
-the phantom-required-check class
-(`feedback_phantom_required_check_after_gitea_migration`).
-
-The inverse direction (emitter without BP context) is INFORMATIONAL
-only — Tier 2g handles that direction at PR-time. Flagging it here
-on a daily schedule would falsely surface every transitional state
-during a BP rollout.
-
-How the gate works
-------------------
-Daily scheduled run + workflow_dispatch:
-
-  1. GET `branch_protections/{BRANCH}` (needs DRIFT_BOT_TOKEN with
-     repo-admin scope; same persona as ci-required-drift.yml).
-     Graceful-degrade on 403/404 per Tier 2a contract.
-
-  2. Walk `.gitea/workflows/*.yml` via PyYAML AST. For each workflow,
-     enumerate its emitted contexts: `{workflow.name} / {job.name or
-     job-key} ({event})` for each event in `on:` that emits a status.
-
-  3. For each BP context, look for an emitter match. Aggregate
-     orphans.
-
-  4. If orphans exist:
-     - File or PATCH a `[ci-bp-drift]` issue (idempotency contract:
-       search for exact title prefix, edit existing if open).
-     - Apply labels `tier:high` + `ci-bp-drift` (lookup IDs per
-       repo; per `feedback_tier_label_ids_are_per_repo`).
-     - Exit 1.
-
-  5. If no orphans:
-     - Close any existing `[ci-bp-drift]` issue with a clean-state
-       comment.
-     - Exit 0.
-
-Exit codes
-----------
-  0 — clean OR API 403/404 (graceful-degrade, surfaces ::error::).
-  1 — at least one BP context has no emitter.
-  2 — env contract violation, workflows-dir missing, or YAML parse
-      error.
-
-Env

-#!/usr/bin/env python3
-"""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 \\

-
-Rule
-----
-When a PR adds a NEW commit-status emission (a context that didn't
-exist on the base side), the workflow file must carry one of three
-directive comments adjacent to the new job:
-
-  (a) `# bp-required: yes`
-      The new context MUST already be in
-      `branch_protections/<branch>.status_check_contexts`. Verified
-      via Gitea API at PR time.
-
-  (b) `# bp-required: pending #NNN`
-      Acknowledged asymmetry; references an OPEN tracking issue that
-      will follow up with the BP PATCH.
-
-  (c) `# bp-exempt: <free-text reason>`
-      Informational job, not intended to be a required gate.
-
-No directive on a new emitter → FAIL with a 3-option fix-hint.
-
-The class this prevents
------------------------
-PR#656 added `CI / all-required (pull_request)` as a sentinel context
-that workflows emit, but BP did NOT list it. When `platform-build`
-failed, `all-required` failed, but BP let the PR merge anyway →
-cascade to mc#664. With this lint, PR#656 would have been blocked
-until either the BP PATCH ran alongside OR the author added a
-`bp-required: pending` directive.
-
-Why directives MUST live in the workflow YAML
----------------------------------------------
-The directive comment lives with the emitter so a scheduled
-audit (Tier 2f, daily) can read the same source. PR-body-only
-directives invisibly evaporate on merge — the asymmetry would
-return to undetected. PR-body claims are advisory; workflow-file
-comments are the contract.
-
-How "new emission" is detected
-------------------------------
-Diff base..head over `.gitea/workflows/*.yml`. For each YAML file
-that's added or modified:
-  - Parse both base-side and head-side via PyYAML AST.
-  - Enumerate emitted contexts on each side using the same rules as
-    Tier 2f (workflow.name + job.name|key + event-mapping).
-  - `new_contexts = head_contexts - base_contexts`.
-
-If `new_contexts` is empty after de-dup, no rule applies → pass.
-
-Per `feedback_behavior_based_ast_gates`: comment scanning uses raw
-text in a small window around the job-key line, NOT regex over the
-full file. This avoids matching `bp-required:` mentioned in a
-comment unrelated to the new job.
-
-Exit codes
-----------
-  0 — no new emissions, all new emissions have valid directives,
-      or BP read errored (graceful-degrade per Tier 2a contract).
-  1 — at least one new emission lacks a directive, or has
-      `bp-required: yes` but the context is missing from BP.
-  2 — env contract violation or YAML parse error.
-

-# Tier 2f scheduled lint (per mc#774) — detects drift between
-# `branch_protections/<branch>.status_check_contexts` and the set of
-# contexts emitted by `.gitea/workflows/*.yml`.
-#
-# Rule
-# ----
-# For each protected branch context (Source A — BP), there must exist
-# at least one emitting workflow + job pair (Source B — workflow YAML
-# + on:-event mapping) whose runtime status-name maps to it. The
-# inverse direction (emitter without BP context) is informational
-# only — Tier 2g handles that at PR-time.
-#
-# Why this exists
-# ---------------
-# A BP-required context with no emitter blocks merges forever — Gitea
-# 1.22.6 treats absent-as-`pending`, NOT absent-as-`skipped`. The
-# phantom-required-check class previously surfaced as
-# `feedback_phantom_required_check_after_gitea_migration` (a port
-# kept the GitHub context name after rename to Gitea, but no
-# workflow emitted under the new name).
-#
-# This lint catches the same class structurally + a forward case:
-# workflow renamed/deleted while still in BP.
-#
-# Scope
-# -----
-# Scheduled daily. We DON'T run on `pull_request` because (a) the
-# emitter side moves with PR diffs (transitional state false-flags)
-# and (b) Tier 2g handles emitter-side drift at PR-time.
-#
-# Cross-repo
-# ----------
-# Today this runs only on molecule-core/main. Per internal#349
-# (cross-repo BP sweep) Class-D repos will get the same lint after
-# their BP rollouts.
-#
-# Auth
-# ----
-# `GET /repos/.../branch_protections/{branch}` requires repo-admin
-# role on Gitea 1.22.6. We use DRIFT_BOT_TOKEN (same persona as
-# ci-required-drift.yml — `internal#329` provisioning trail).
-# Graceful-degrade per Tier 2a contract: 403/404 → exit 0 with
-# ::error::.
-#
-# Idempotency
-# -----------
-# The drift issue is filed with title prefix
-# `[ci-bp-drift] {repo}/{branch}: BP→emitter mismatch`. The script
-# searches OPEN issues for an exact title-prefix match and PATCHes
-# the existing issue (if any) instead of POSTing a duplicate.
-# Mirrors `ci-required-drift.py`'s contract.
-#
-# Phase contract (RFC internal#219 §1 ladder)
-# -------------------------------------------
-# Lands at `continue-on-error: true` (Phase 3). After 7 days of clean
-# scheduled runs on `main`, flip to `false` so a scheduled failure
-# becomes a hard CI signal.

-#      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
-#      only working path, see also
-#      `reference_gitea_1_22_6_lacks_rest_rerun_endpoints`).
-#   5. Grep each log for `--- FAIL`, `FAIL\s`, `::error::`. If
-#      the status is `success` but the log shows any of these,
-#      the job was masked. Block the PR with `::error::`.

-name: lint-required-context-exists-in-bp

-# Tier 2g hard-gate lint (per mc#774) — diff-based PR-time
-# check. When a PR adds a NEW commit-status emission (workflow YAML
-# `name:` + job `name:`-or-key + on:-event), the workflow file must
-# carry one of three directives adjacent to the new job:
-#
-#   - `# bp-required: yes`           — and BP must list the context
-#   - `# bp-required: pending #NNN`  — acknowledged asymmetry + tracker
-#   - `# bp-exempt: <reason>`        — informational job, not a gate
-#
-# Default (no directive on a new emitter) = FAIL.
-#
-# Why this exists
-# ---------------
-# PR#656 added `CI / all-required (pull_request)` as a sentinel
-# context that workflows emit, but BP did NOT list it. When
-# platform-build failed, all-required failed, but BP let the PR
-# merge anyway → cascade to mc#774. With this lint, PR#656 would
-# have been blocked until either the BP PATCH ran alongside OR
-# the author added a `bp-required: pending` directive.
-#
-# Tier 2g vs Tier 2f
-# ------------------
-# Tier 2g runs at PR-time (diff-based) and BLOCKS the merge.
-# Tier 2f runs daily (scheduled) and FILES a drift issue. They
-# share the workflow-context enumeration helpers
-# (`_event_map`, `workflow_contexts`, `_job_display`) but the
-# semantics are intentionally distinct so they're separate scripts.
-# Co-design is documented in mc#774.
-#
-# Directive comment lives in the workflow file (NOT PR body)
-# ----------------------------------------------------------
-# A PR-body claim of "BP exempt" evaporates on merge — the
-# asymmetry returns to undetected state and Tier 2f's daily
-# scheduled audit can't see it. The directive must live with the
-# emitter so both PR-time (Tier 2g) and post-merge (Tier 2f)
-# readers consume the same source.
-#
-# Phase contract (RFC internal#219 §1 ladder)
-# -------------------------------------------
-# Lands at `continue-on-error: true` (Phase 3 — surface the
-# pattern without blocking PRs while the directive convention
-# beds in). After 7 days of clean runs on `main` with no false
-# positives, follow-up flips to `false`. Tracking: mc#774.

-"""Tests for `.gitea/scripts/lint_bp_context_emit_match.py` — Tier 2f lint.
-
-Structural enforcement of internal#350 Tier 2f: BP `status_check_contexts`
-and the set of contexts emitted by `.gitea/workflows/*.yml` must agree.
-
-Bidirectional rule:
-  (a) BP-only: every context in `branch_protections/<branch>.status_check_contexts`
-      must have at least one EMITTER — a workflow `name:` + job `name:` (or job key)
-      + `pull_request` (or `push`) event that produces it. A BP context without
-      an emitter blocks merges forever (Gitea treats absent-as-pending, NOT
-      absent-as-skipped). This is the phantom-required-check class
-      (`feedback_phantom_required_check_after_gitea_migration`).
-
-  (b) EMITTER-only: NO automatic flag. The PR#656 case (workflow added a
-      sentinel context not yet in BP) is Tier 2g's job — a diff-based PR-time
-      lint. Tier 2f runs scheduled and would falsely flag every transitional
-      state during a BP rollout. We only flag the BP-empty case in this
-      direction as a NOTICE (informational), not as an error.
-
-Tier 2f runs on a daily schedule + workflow_dispatch and files a
-`[ci-bp-drift]`-tagged issue on mismatch.
-
-Test classes (per `feedback_branch_count_before_approving`):
-
-  - test_perfect_match_passes              — BP has [X]; workflows emit X.
-    Exit 0. No issue filed/edited.
-  - test_bp_orphan_context_fails           — BP has [Y] but no workflow
-    emits Y. Exit 1. Issue body lists the orphan and the closest
-    candidate workflow names (Levenshtein-1 suggestion for typos).
-  - test_emitter_orphan_only_warns         — workflow emits Z but BP
-    doesn't have it. Exit 0 with ::notice:: (NOT ::error::) because
-    Tier 2g handles this at PR time.
-  - test_multiple_orphans_aggregated       — two BP orphans surfaced
-    together, not short-circuited.
-  - test_bp_empty_lints_nothing            — BP has no contexts.
-    Exit 0 cleanly.
-  - test_api_403_skips_gracefully          — branch_protections endpoint
-    403s (token-scope). Exit 0 with ::error::, do NOT red-X.
-  - test_api_404_skips_gracefully          — branch has no protection.
-    Exit 0 cleanly.
-  - test_context_event_match_required      — BP context says `(push)` and
-    workflow only emits on `pull_request`. That's NOT a match — the
-    BP-required gate would still wedge. Exit 1.
-  - test_workflow_event_mapping_pull_request_target — `pull_request_target`
-    in workflow `on:` emits a `(pull_request)` context (Gitea convention).
-    Match counts.
-  - test_idempotent_issue_filing           — when an issue already exists
-    with the canonical title prefix, edit it instead of POSTing a new one
-    (idempotency contract — mirrors ci-required-drift).

-"""Tests for `.gitea/scripts/lint_required_context_exists_in_bp.py` — Tier 2g lint.
-
-Structural enforcement of internal#350 Tier 2g: when a PR adds a NEW
-commit-status emission (a workflow's `name:` + a new job-key/name pair
-that didn't exist on the base side), the PR must EITHER:
-
-  (a) Include a `# bp-required: yes` directive comment on the workflow
-      AND the new context must already be in
-      `branch_protections/<branch>.status_check_contexts`, OR
-
-  (b) Include a `# bp-required: pending #NNN` directive (acknowledged
-      asymmetry with a tracking issue), OR
-
-  (c) Include a `# bp-exempt: <reason>` directive (informational job,
-      not intended to be a required gate).
-
-Default (no directive on a new emitter) = FAIL.
-
-The class this prevents
------------------------
-PR#656 added `CI / all-required (pull_request)` as a sentinel context
-that workflows emit, but BP did NOT list it — so when `platform-build`
-failed, `all-required` failed, but BP let the PR merge anyway. Cascade
-to mc#664. With Tier 2g, PR#656 would have been blocked until either
-the BP PATCH ran alongside OR the author marked the emission with a
-`bp-required: pending #NNN` directive.
-
-Test classes (per `feedback_branch_count_before_approving`):
-
-  - test_no_new_emissions_skips                   — diff doesn't add any
-    new emitter; pass.
-  - test_new_emission_with_bp_required_yes_in_bp  — directive set AND
-    BP lists the context; pass.
-  - test_new_emission_with_bp_required_yes_not_in_bp — directive set
-    BUT BP doesn't list; fail.
-  - test_new_emission_with_bp_required_pending    — `# bp-required:
-    pending #800` directive references an open tracker; pass.
-  - test_new_emission_with_bp_exempt              — `# bp-exempt:
-    informational` directive; pass.
-  - test_new_emission_no_directive_fails          — no directive on a
-    new emission; fail with the 3-option fix-hint.
-  - test_modified_workflow_with_new_job_is_new    — pre-existing
-    workflow gains a new job with a new name → counted as new
-    emission. Apply rule.
-  - test_modified_workflow_job_renamed_is_new     — same workflow,
-    same job-key, but job `name:` changed → counted as new emission
-    (the OLD context name disappears; the NEW one needs validation).
-  - test_unrelated_workflow_edit_is_not_new       — edit a comment in
-    an existing emitter; no new context introduced; pass.
-  - test_api_403_skips_gracefully                 — BP read 403; exit 0
-    with stderr ::error::.
-  - test_directive_must_be_in_workflow_yml        — directive in PR
-    body alone is NOT sufficient; the comment must live in the
-    workflow file so future scheduled Tier 2f runs can see it.

-// delegation_executor_integration_test.go — REAL Postgres integration tests for
-// executeDelegation HTTP proxy edge cases that sqlmock cannot cover.
-//
-// The sqlmock tests in delegation_test.go pin which SQL statements fire but
-// cannot detect bugs that depend on the row state AFTER the SQL runs. The
-// result_preview-lost bug shipped to staging in PR #2854 because sqlmock tests
-// were satisfied with "an UPDATE fired" — none verified the row's preview
-// field actually landed. These integration tests close that gap.
-//
-// How HTTP is mocked
-// -----------------
-// We use raw TCP listeners (net.Listener) instead of httptest.Server to avoid
-// any HTTP-library-level goroutine complexity. The test opens a TCP port,
-// serves one HTTP response, then closes the connection. The a2aClient transport
-// is overridden with a DialContext that intercepts all dials and redirects to
-// the test server's port. No DNS, no TCP handshake overhead, no HTTP library
-// goroutines that could block on request-body reads.
-//
-// Run with:
-//
-//   docker run --rm -d --name pg-integration \
-//     -e POSTGRES_PASSWORD=test -e POSTGRES_DB=molecule \
-//     -p 55432:5432 postgres:15-alpine
