Merge pull request 'test: satisfy staticcheck on PR regression tests' (#1043) from fix/staticcheck-pr-regression-tests into main

Regression from audit #109: rows.Err() checks were removed from List,
ListGlobal, restartAllAffectedByGlobalKey, and Values between commits
3a30b073 and b25b4fb6. Without these checks, a mid-stream query error
(e.g. connection loss during iteration) is silently ignored and partial
results are returned as if the query succeeded.

Fix: add if err := rows.Err(); err != nil { log.Printf(...) } after
every for rows.Next() loop in secrets.go.

+queue. This script provides the missing serialized policy in user space:
+
+1. Pick the oldest open PR carrying QUEUE_LABEL.
+2. Refuse to act unless main is green.
+3. Refuse fork PRs; the queue may only mutate same-repo branches.
+4. If the PR branch does not contain current main, call Gitea's
+   /pulls/{n}/update endpoint and stop. CI must rerun on the updated head.
+5. If the updated PR head has all required contexts green, merge with the
+   non-bypass merge actor token.
+
+The script is intentionally one-PR-per-run. Workflow/cron concurrency should
+serialize invocations so two green PRs cannot merge against the same main.

+"""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)

+"""lint_continue_on_error_tracking — Tier 2e per internal#350.
+
+Rule
+----
+Every `continue-on-error: true` directive in `.gitea/workflows/*.yml`
+must be accompanied by a tracker reference comment within 2 lines
+(above OR below the directive's line). The reference is one of:
+
+  * `# mc#NNNN`          — molecule-core issue
+  * `# internal#NNNN`    — molecule-ai/internal issue
+
+The referenced issue must satisfy ALL of:
+
+  1. Exists (HTTP 200 on `/repos/{owner}/{name}/issues/{num}`)
+  2. `state == "open"`
+  3. `created_at` is ≤ MAX_AGE_DAYS days ago (default 14)
+
+A passing reference establishes an audit trail and a forced renewal
+cadence — after 14 days the issue must either be CLOSED (the masked
+defect was fixed) or the comment must point at a NEW tracker
+(deliberate decision to keep masking, requires a paper-trail).
+
+The class this prevents
+-----------------------
+Phase-3-masked failures. `continue-on-error: true` on `platform-build`
+had been hiding mc#664-class regressions for ~3 weeks before #656
+surfaced them on 2026-05-12. A 14-day cap forces a tracker review
+cycle and surfaces mask-drift within at most 14 days of the original
+defect.
+
+Behaviour-based gate
+--------------------
+We parse via PyYAML AST (per `feedback_behavior_based_ast_gates`) to
+detect `continue-on-error: <truthy>` at job-key level, then map each
+location back to its source line via PyYAML's line-tracking loader.
+Comments are scanned from the raw text within a 2-line window of
+that source line. Reformatting (block-scalar vs flow-style) does not
+break the rule because the source-line anchor is the directive's
+own line.
+
+Exit codes
+----------
+  0 — every `continue-on-error: true` has a passing tracker, OR
+      the issue-API endpoint returned 403/404 (token-scope; graceful
+      degrade per Tier 2a contract — surface via ::error:: on stderr
+      but don't red-X every PR over auth).
+  1 — at least one violation (missing/closed/too-old/non-existent
+      tracker).
+  2 — env contract violation, YAML parse error, or workflows-dir
+      missing.
+
+Env
+---
+  GITEA_TOKEN     — read scope on the configured repos.
+                    Auto-injected `GITHUB_TOKEN` works for same-repo
+                    issue reads; for `internal#NNN` we need a token
+                    with `molecule-ai/internal` read scope. Use
+                    DRIFT_BOT_TOKEN (same persona as other Tier 2
+                    lints).
+  GITEA_HOST      — e.g. git.moleculesai.app
+  REPO            — `owner/name` for `mc#NNNN` lookups
+  INTERNAL_REPO   — `owner/name` for `internal#NNNN` lookups
+                    (defaults to derived `molecule-ai/internal`)
+  WORKFLOWS_DIR   — defaults to `.gitea/workflows`
+  MAX_AGE_DAYS    — defaults to 14

+"""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 \\

+"""lint_required_context_exists_in_bp — Tier 2g per internal#350.
+
+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.
+
+Env
+---
+  BASE_SHA          — PR base SHA
+  HEAD_SHA          — PR head SHA
+  GITEA_TOKEN       — DRIFT_BOT_TOKEN (repo-admin for BP read)
+  GITEA_HOST        — e.g. git.moleculesai.app
+  REPO              — owner/name
+  BRANCH            — defaults to `main`
+  WORKFLOWS_DIR     — defaults to `.gitea/workflows`

+
+# 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.

+name: lint-continue-on-error-tracking
+
+# Tier 2e hard-gate lint (per mc#774) — every
+# `continue-on-error: true` in `.gitea/workflows/*.yml` must carry a
+# `# mc#NNNN` or `# internal#NNNN` tracker comment within 2 lines,
+# the referenced issue must be OPEN, and ≤14 days old.
+#
+# Why this exists
+# ---------------
+# `continue-on-error: true` on `platform-build` had been hiding
+# mc#774-class regressions for ~3 weeks before #656 surfaced them on
+# 2026-05-12. A 14-day cap on tracker age forces a review cycle and
+# surfaces mask-drift within at most 14 days of the original defect.
+# Each `continue-on-error: true` gets a paper trail — close or renew.
+#
+# How the gate works
+# ------------------
+# 1. Walk `.gitea/workflows/*.yml` via PyYAML's line-tracking loader
+#    (per `feedback_behavior_based_ast_gates`) and find every job
+#    whose `continue-on-error` evaluates truthy (`true` or string
+#    `"true"` — Gitea's evaluator coerces strings).
+# 2. For each, scan ±2 lines of the directive's source line for a
+#    `# mc#NNNN` or `# internal#NNNN` comment. Inline-trailing
+#    comments on the directive line count.
+# 3. For each tracker reference, GET the issue from the Gitea API.
+#    Validate: exists, `state == open`, `created_at` ≤ MAX_AGE_DAYS.
+# 4. Aggregate ALL violations (not short-circuit) and exit 1 if any.
+#
+# Triggers
+# --------
+# Runs on PR events (paths-filter on `.gitea/workflows/**`) AND on
+# a daily schedule. PR runs catch the violation at introduction time.
+# Schedule runs catch the AGE-EXPIRY class: a tracker that was ≤14d
+# old when the PR landed but is now 20d old, with the underlying
+# defect still unfixed. Per `feedback_chained_defects_in_never_tested_workflows`,
+# scheduled drift detection is the second half of the gate.
+#
+# Phase contract (RFC internal#219 §1 ladder)
+# -------------------------------------------
+# Lands at `continue-on-error: true` (Phase 3 — surface broken shapes
+# without blocking). The pre-existing `continue-on-error: true`
+# directives on `main` will all violate this lint at first
+# (intentional — they're the masked defects this lint exists to
+# surface). Each must be triaged: file a fresh tracker comment,
+# close-and-flip, or document the deliberate keep-mask in a fresh
+# 14-day-renewable tracker. After main is clean for 3 days,
+# follow-up PR flips this workflow's continue-on-error to false.
+# Tracking: mc#774.

+# Empirical class: PR #656 / mc#774. PR #656 (RFC internal#219 Phase 4)
+# flipped 5 platform-build-class jobs `continue-on-error: true → false`

+# 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

+# Codified 04:35Z as hongming-pc2 charter §SOP-N rule (e)

+# 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
+#      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::`.
+#
+# Graceful-degrade contract (per task halt-conditions):
+#   - Log fetch 404 (act_runner pruned the log, transient outage):
+#     emit `::warning::` "log unavailable" — does NOT block.
+#   - Zero recent runs of the flipped job's context on the base
+#     branch (newly added workflow): emit `::warning::` "no run
+#     history to verify" — allow the flip. Chicken-and-egg
