fix(platform): /github-installation-token returns 501 on missing config (closes #388)

When GITHUB_APP_ID/INSTALLATION_ID are unset (post org suspension or
Gitea-canonical deployments without GitHub App), the fallback path in
GetInstallationToken was returning 500 Internal Server Error. This pollutes
platform logs with ~28×false-positive 500s/hour across all workspaces.

Return 501 Not Implemented with {"error":"GitHub integration not
configured","scm":"gitea"} when the "required" error fires — callers
can now distinguish "feature off" from "transient error" and stop polling.

Update TestGitHubToken_NoTokenProvider to assert the new 501 shape.

-# sop-checklist-gate — evaluate whether a PR has peer-acked each
-# SOP-checklist item. Posts a commit-status that branch protection
-# can require.
-#
-# RFC#351 Step 2 of 6 (implementation MVP).
-#
-# Invoked by .gitea/workflows/sop-checklist-gate.yml on:
-#   - pull_request_target: [opened, edited, synchronize, reopened]
-#   - issue_comment:       [created, edited, deleted]
-#
-# Flow:
-#   1. Load .gitea/sop-checklist-config.yaml (from BASE ref — trusted).
-#   2. GET /repos/{R}/pulls/{N}          — author, head.sha, tier label
-#   3. GET /repos/{R}/issues/{N}/comments — extract /sop-ack and /sop-revoke
-#   4. For each checklist item:
-#        a. Is the section marker present in PR body? (author answered)
-#        b. Is there ≥1 unrevoked /sop-ack from a non-author whose
-#           team-membership matches required_teams?
-#   5. POST /repos/{R}/statuses/{sha}    — context
-#      `sop-checklist / all-items-acked (pull_request)`,
-#      state=success | failure | pending, description=`acked: N/M …`.
-#
-# Trust boundary (mirrors RFC#324 §A4):
-#   This script is loaded from the BASE branch. The workflow's
-#   actions/checkout step pins ref=base.sha. PR-HEAD code is never
-#   executed. We only HTTP-call the Gitea API.
-#
-# Token scope:
-#   - read:repository / read:organization to enumerate PR + comments
-#     + team membership (Gitea 1.22.6 quirk: team-membership endpoint
-#     returns 403 if token owner is not in the team; see review-check.sh
-#     for the same gotcha — we surface the same fail-closed message).
-#   - write:repository for `POST /repos/{R}/statuses/{sha}`. Unlike
-#     RFC#324's pattern (which uses the JOB's own pass/fail as the
-#     status), we POST the status explicitly because the gate posts
-#     a single multi-item status with a richer description than a
-#     bare success/failure context can carry.
-#
-# Slug normalization rules (canonical form: kebab-case):
-#   - Lowercase
-#   - Whitespace + underscores → single dash
-#   - Strip non [a-z0-9-] characters
-#   - Collapse adjacent dashes
-#   - Strip leading/trailing dashes
-#   - If the result is a digit string (e.g. "1"), look up via
-#     config.items[*].numeric_alias to get the kebab-case slug.
-#
-#   Examples:
-#       "Comprehensive_Testing"  → "comprehensive-testing"
-#       "comprehensive testing"  → "comprehensive-testing"
-#       "1"                      → "comprehensive-testing"
-#       "Five-Axis-Review"       → "five-axis-review"
-#
-# Revoke semantics:
-#   /sop-revoke <slug> [reason] — most-recent comment per (slug, user)
-#   wins. So if Alice posts /sop-ack X then later /sop-revoke X, her ack
-#   for X is invalidated. Bob's prior /sop-ack X is unaffected. If Alice
-#   posts /sop-revoke X then later /sop-ack X again, the ack is restored.

-#   slug              — canonical kebab-case form used in /sop-ack <slug>
-#   pr_section_marker — substring matched in the PR body to detect that
-#                       the author filled in this item (case-insensitive)
-#   required_teams    — list of Gitea team names; an ack from ANY one of
-#                       these teams (logical OR) satisfies the item.
-#                       Membership is probed at gate-time via
-#                       GET /api/v1/teams/{id}/members/{login}.
-#                       Team-id resolution happens at script start via
-#                       GET /api/v1/orgs/{org}/teams (cheap, one call).
-#   numeric_alias     — 1..7; lets reviewers type `/sop-ack 3` as a
-#                       shortcut for `/sop-ack staging-smoke`.
-#
-# WHY THESE TEAM MAPPINGS:
-#   The RFC table referenced persona-role names like `core-qa`,
-#   `core-be`, `core-devops` — these are individual Gitea user logins,
-#   not teams. The Gitea team-membership API is /teams/{id}/members/{u},
-#   so we need actual teams. Orchestrator preflight 2026-05-12 verified
-#   only these teams exist on molecule-ai: ceo(5), engineers(2),
-#   managers(6), qa(20), security(21), Owners(1), and bot teams. We
-#   map the RFC roles to the closest existing team and surface the
-#   mapping explicitly so it's reviewable.
-#
-# HOW TO EDIT:
-#   - Tightening: replace `engineers` with a smaller team after creating
-#     it (e.g. a new `senior-engineers` team if needed).
-#   - Loosening: add another team to required_teams (OR semantics).
-#   - Add an item: append to items list and document the slug below.
-#
-# AUTHOR SELF-ACK IS FORBIDDEN regardless of which team contains them
-# — the gate script enforces commenter != PR author before checking
-# team membership.

-# (feedback_gitea_actions_migration_audit_pattern) was performed against this
-# port:
-#
-#   1. YAML — dropped `merge_group` trigger (no Gitea merge queue); no

-#      feedback_gitea_workflow_dispatch_inputs_unsupported); no `environment:`
-#      blocks; kept `runs-on: ubuntu-latest` (Gitea runner pool advertises
-#      this label per agent_labels in action_runner table). Workflow-level
-#      env.GITHUB_SERVER_URL set as belt-and-suspenders against runner
-#      defaults (feedback_act_runner_github_server_url).
-#
-#   2. Cache — `actions/upload-artifact@v3.2.2` was already pinned to v3 for
-#      Gitea act_runner v0.6 compatibility (a comment in the original called
-#      this out). v4+ is incompatible with Gitea 1.22.x. No `actions/cache`

-#      is configured (currently is, /opt/molecule/runners/config.yaml).
-#
-#   3. Token — workflow uses no custom dispatch tokens. The auto-injected
-#      `GITHUB_TOKEN` (which Gitea aliases to a runner-scoped token) is
-#      sufficient for `actions/checkout` against this same repo.
-#
-#   4. Docs — no docs/scripts reference github.com URLs that need swapping.

-    #  1. `if: always()` — runs even when an upstream fails. Without it the

-    #  2. Assertion is `result == "success"` per dep, NOT `!= "failure"`.
-    #     A `skipped` upstream (job gated by `if:` evaluating false, matrix
-    #     entry that couldn't run) must NOT silently pass through.
-    #     `skipped`-as-green is exactly the failure mode this gate closes.

-    #  3. `needs:` is the canonical list of "what counts as required."
-    #     status_check_contexts will reference only `ci/all-required` (Step 5
-    #     follow-up — branch-protection PATCH is Owners-tier per
-    #     `feedback_never_admin_merge_bypass`, separate PR); a new job is
-    #     added simply by listing it in `needs:` here.

-    #
-    # Excluded from `needs:`: `canvas-deploy-reminder` — gated by
-    # `if: ... github.event_name == 'push' && github.ref == 'refs/heads/main'`,
-    # so on PR events it's legitimately `skipped`. The drift detector
-    # explicitly excludes `github.event_name`-gated jobs from F1 (see
-    # `.gitea/scripts/ci-required-drift.py::ci_job_names`).
-    #
-    # Phase 3 (RFC #219 §1) safety: underlying build jobs carry
-    # continue-on-error: true so their failures are masked to null (2026-05-12: re-enabled mc#774 interim)
-    # (Gitea suppresses status reporting for CoE jobs). This sentinel
-    # runs with continue-on-error: false so it always reports its
-    # result to the API — without this, the required-status entry
-    # (CI / all-required (pull_request)) is never created, which
-    # blocks PR merges. When Phase 3 ends, flip underlying jobs to
-    # continue-on-error: false; this sentinel can then be flipped to

+# Why this file exists (issue #351):
+#   Gitea Actions does not correctly disambiguate `paths:` from `tags:`
+#   when both are bundled under a single `on.push` key. The result is
+#   that tag pushes get filtered out and `publish-runtime.yml` never
+#   fires — `action_run` rows: 0. This was unnoticed pre-2026-05-11
+#   because PYPI_TOKEN was absent (publishes would have failed anyway).
+#
+#   Split design:
+#     - publish-runtime.yml         : on.push.tags only        (the publisher)
+#     - publish-runtime-autobump.yml: on.push.branches+paths   (this file — the version-bumper)
+#
+#   This file computes the next version from PyPI's latest, pushes a
+#   `runtime-v$VERSION` tag, and exits. The tag push then triggers
+#   publish-runtime.yml via its tags-only trigger.
+#
+# Concurrency: shares the `publish-runtime` group with publish-runtime.yml
+# so concurrent workspace pushes serialize at the bump step. Without
+# this, two pushes minutes apart could both read PyPI latest=0.1.129

-# sop-checklist-gate — peer-ack merge gate for SOP-checklist items.
-#
-# RFC#351 Step 2 of 6 (implementation MVP).
-#
-# === DESIGN ===
-#
-# Goal: each PR must answer 7 SOP-checklist questions in its body,
-# and each item must have at least one /sop-ack <slug> comment from
-# a non-author peer in the required team. BP requires the
-# `sop-checklist / all-items-acked (pull_request)` status to merge.
-#
-# Triggers:
-#   - `pull_request_target`: opened, edited, synchronize, reopened
-#       → fires when PR opens, body is edited (refire — RFC#351 §4),
-#         or new code is pushed (head.sha changes → stale status would
-#         be auto-discarded by BP via dismiss_stale_reviews, but the
-#         status itself is per-SHA so we re-post on the new head).
-#   - `issue_comment`: created, edited, deleted
-#       → fires on any new comment so /sop-ack / /sop-revoke take
-#         effect immediately (Gitea 1.22.6 doesn't refire on
-#         pull_request_review per feedback_pull_request_review_no_refire,
-#         so issue_comment is the canonical refire channel).
-#
-# Trust boundary (mirrors RFC#324 §A4 + sop-tier-check security note):
-#   `pull_request_target` (not `pull_request`) — workflow def is loaded
-#   from BASE branch, so a PR cannot rewrite this workflow to exfiltrate
-#   the token. The `actions/checkout` step pins `ref: base.sha` so the
-#   script ALSO comes from BASE. PR-HEAD code is never executed in the
-#   runner.
-#
-# Token scope:
-#   - read:repository, read:organization for PR + comments + team probes
-#   - write:repository for POST /statuses/{sha}
-#   - The token owner MUST be a member of every team referenced by the
-#     config's required_teams (else /teams/{id}/members/{login} returns
-#     403 — see review-check.sh same-gotcha doc). For the MVP we use
-#     the dev-lead token (a member of engineers, managers, qa, security)
-#     via a repo secret `SOP_CHECKLIST_GATE_TOKEN`. Provisioning of that
-#     secret is a follow-up authorization step (separate from this PR).
-#
-# Failure mode: tier-aware (RFC#351 open question 2):
-#   - tier:high   → state=failure (hard-fail; BP blocks merge)
-#   - tier:medium → state=failure (hard-fail; same)
-#   - tier:low    → state=pending (soft-fail; BP can choose to require
-#                    this context or skip for low-tier PRs)
-#   - missing/no-tier → state=failure (default-mode: hard — never lower
-#                    the bar per feedback_fix_root_not_symptom)
-#
-# Slash-command contract (RFC#351 v1 + §A1.1-style notes from RFC#324):
-#
-#   /sop-ack <slug-or-numeric-alias> [optional note]
-#       — register a peer-ack for one checklist item.
-#       — slug accepts kebab-case, snake_case, or natural-spaces
-#         (all normalize to canonical kebab-case).
-#       — numeric 1..7 maps via config.items[*].numeric_alias.
-#       — most-recent (user, slug) directive wins.
-#
-#   /sop-revoke <slug-or-numeric-alias> [reason]
-#       — invalidate the commenter's own prior /sop-ack for this slug.
-#       — does NOT affect other peers' acks on the same slug.
-#       — most-recent (user, slug) directive wins, so a later /sop-ack
-#         re-restores the ack.
-#
-# The eval is read-only + idempotent (read PR + comments + team
-# membership, compute, post status). Re-running on any event is safe —
-# the new status overwrites the previous one for the same context.

-      #     :staging-<sha> → :latest. Prod tenants pull :latest.

-      # the canary fleet pin handoff.

-      # Pre-fix history: this workflow used to only trigger on main. That
-      # meant staging-CP served "yesterday's main" indefinitely whenever
-      # staging→main was wedged. The 2026-04-30 dogfooding session

- * Tests for DropTargetBadge — the floating drag-target affordance.
- *
- * Two-layer visual contract:
- *   1. Ghost preview — dashed rect at the next default child slot
- *   2. Text badge — "Drop into: <name>" floating above the target
- *
- * Render-condition coverage:
- *   - Renders nothing when dragOverNodeId is null
- *   - Renders nothing when dragOverNodeId node has no name (store lookup misses)
- *   - Renders nothing when getInternalNode returns undefined
- *   - Renders badge with correct name when all inputs are valid
- *   - Badge text contains the target node name
- *
- * Note: Ghost visibility (slot rect inside parent bounds) involves
- * flowToScreenPosition coordinate arithmetic that's better covered by
- * integration tests that render the full canvas. Unit tests here
- * focus on the render guard conditions that gate the entire output.
- *
- * Issue: #2071 (Canvas test gaps follow-up).

-// Background (#2872 + post-2026-05-06 follow-up):
-//   - Migration 20260506000000_workspaces_unique_parent_name added a
-//     partial UNIQUE index on (COALESCE(parent_id, sentinel), name)
-//     WHERE status != 'removed'. It exists to close the TOCTOU race in
-//     /org/import that previously let two concurrent POSTs both INSERT
-//     the same (parent_id, name) row.
-//   - /org/import handles the constraint via `ON CONFLICT DO NOTHING`
-//     + idempotent re-select (handlers/org_import.go).
-//   - The Canvas Create handler (handlers/workspace.go) did NOT — a
-//     duplicate POST returned an opaque HTTP 500 with the raw pq error
-//     in the server log. Repro path: user clicks a template card twice
-//     in canvas before the first response paints.
-//
-// Resolution: auto-suffix the user-typed name on collision. The
-// uniqueness constraint required for #2872 stays in place; only the
-// Canvas Create path's reaction to it changes. Names become a
-// free-form display label that the platform disambiguates; row
-// identity is carried by the workspace id (UUID).
-//
-// Suffix shape: " (2)", " (3)", … up to N=maxNameSuffix. Chosen over
-// numeric "-2" / "_2" because the parenthesised form is the standard
-// disambiguation pattern users already expect from Finder / Explorer
-// / Google Docs / file managers. Stays under the 255-char name cap

+"""OFFSEC-003: A2A peer-result sanitization — shared across delegation tools.
 
-OFFSEC-003: Peer text must not be able to escape trust boundaries by
-injecting control markers that the caller interprets as structured framing.
+This module is intentionally a LEAF (no imports from the molecule-runtime
+package) to avoid circular dependency cycles. Both ``a2a_tools_delegation``
+and ``a2a_tools`` can import from here without creating import loops.
 
-This module is intentionally isolated from the rest of the molecule-runtime
-import graph to avoid circular imports. Callers import only from here when
-they need to sanitize a2a result text before returning it to the agent.
+Trust-boundary design (OFFSEC-003):
+    A2A peer responses are untrusted third-party content. Before passing
+    them to the agent context, they MUST be wrapped in a trust-boundary
+    marker pair so the calling agent knows the content is external.
+
+Boundary markers:
+    - _A2A_BOUNDARY_START = "[A2A_RESULT_FROM_PEER]"
+    - _A2A_BOUNDARY_END   = "[/A2A_RESULT_FROM_PEER]"
+
+The boundary is the PRIMARY security control. A peer that sends
+"[A2A_RESULT_FROM_PEER]evil[/A2A_RESULT_FROM_PEER]safe" can make "safe"
+appear inside the trusted context unless the markers themselves are
+escaped before wrapping — see _escape_boundary_markers() below.
+
+Defense-in-depth (secondary):
+    Known prompt-injection control-words are also escaped so that even
+    if a calling agent ignores the boundary marker, embedded attack
+    patterns (SYSTEM:, OVERRIDE:, etc.) lose their special meaning.
+    This is not a complete injection sanitizer — do not rely on it as
+    the primary control.
