-"""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

-  GITEA_TOKEN     — DRIFT_BOT_TOKEN (repo-admin for branch_protections)
-  GITEA_HOST      — e.g. git.moleculesai.app
-  REPO            — owner/name
-  BRANCH          — defaults to `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.

-name: lint-bp-context-emit-match

-# 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

-# 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

-"""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
-//   sleep 4
-//   psql ... < workspace-server/migrations/049_delegations.up.sql
-//   cd workspace-server
-//   INTEGRATION_DB_URL="postgres://postgres:test@localhost:55432/molecule?sslmode=disable" \
-//     go test -tags=integration ./internal/handlers/ -run Integration_ExecuteDelegation
