Summary

Production bug fix for #1959: the Broadcast org-root recursive CTE resolved a non-root sender to itself instead of to the true org root, scoping the broadcast to the wrong subtree.

In workspace-server/internal/handlers/workspace_broadcast.go the org-root CTE anchored id AS root_id to the sender's own id and carried that value unchanged up the parent_id chain. The final SELECT root_id ... WHERE parent_id IS NULL therefore returned the sender's id, not the topmost ancestor's. The OFFSEC-015 org-isolation guarantee held for root senders (sender == root) but was wrong for any child workspace — a child broadcasting resolved itself as the org root.

The fix

Drop the bogus carried root_id column; select the id of the null-parent row (the actual topmost ancestor). The walk direction (JOIN org_chain c ON w.id = c.parent_id, i.e. climb UP to the parent) was already correct.

WITH RECURSIVE org_chain AS (
    SELECT id, parent_id                         -- was: SELECT id, parent_id, id AS root_id
    FROM workspaces WHERE id = $1
    UNION ALL
    SELECT w.id, w.parent_id                      -- was: SELECT w.id, w.parent_id, c.root_id
    FROM workspaces w JOIN org_chain c ON w.id = c.parent_id
)
SELECT id AS root_id FROM org_chain WHERE parent_id IS NULL LIMIT 1  -- was: SELECT root_id ...

Trace (leaf → mid → root): leaf resolves to root, mid resolves to root, root resolves to itself. ✅

Reference: closed staging PR #2090 carried this exact org-root hunk (plus an unrelated dead-struct removal in a2a_proxy_helpers.go). I verified the org-root hunk is correct and applied only that hunk cleanly to current main; the unrelated noise was dropped.

Phase 1 — Inventory

• Broadcast() has two org_chain CTEs: the buggy org-root resolver (~L86) and the recipient-collection CTE (~L106). Only the resolver was wrong — the recipient CTE correctly anchors at parent_id IS NULL and walks down. Fix is confined to the resolver.
• Shared org scoping (org_scope.go, OFFSEC-015 / #1953) uses a separate helper for discovery/peers/a2a; the broadcast handler has its own inline CTE — only the inline one is touched.

Testing

Existing workspace_broadcast_test.go is sqlmock-based: it returns stubbed rows and cannot execute the recursive CTE, so it could not catch this bug. Added a real-Postgres integration test (workspace_broadcast_org_root_integration_test.go, build tag integration, runs under the Handlers Postgres Integration CI context) that seeds a real 3-level chain (root → mid → leaf) and asserts every node — including the deep non-root leaf — resolves to the true root. With the #1959 bug, leaf/mid would resolve to themselves and the test fails.

• go build ./... ✅ ; go vet -tags=integration ./internal/handlers/ ✅
• full go test ./internal/handlers/ (plain) ✅ ; go test -run TestBroadcast ✅

SOP checklist

Comprehensive testing performed: go build ./... clean; go vet -tags=integration ./internal/handlers/ clean; full plain go test ./internal/handlers/ green; TestBroadcast* green. Added a real-Postgres integration test (build tag integration, Handlers Postgres Integration CI) that seeds a 3-level org chain and asserts root/mid/leaf all resolve to the true null-parent root — the sqlmock unit tests cannot execute the CTE so they could not catch #1959.

Local-postgres E2E run: the new integration test IS the local-postgres gate; it runs under the Handlers Postgres Integration required CI context (path filter covers workspace-server/internal/handlers/**). It executes the verbatim handler CTE against real Postgres and fails on any regression to the sender-id-pinned form.

Staging-smoke verified or pending: pending post-merge. This is a read-path SQL fix (no migration, no schema change, no write path); Stage B tenant-probe of a multi-level org's broadcast scoping is the post-merge smoke. No data migration needed.

Root-cause not symptom: root cause is the CTE pinning id AS root_id to the sender at the anchor and never re-deriving it — the fix removes the carried column and selects the true null-parent ancestor's id, not a band-aid on the symptom (wrong recipient set).

Five-Axis review walked: correctness (traced leaf→mid→root; integration test proves it on real Postgres), readability (minimal 3-line SQL diff, walk direction unchanged), architecture (confined to the inline resolver; shared org_scope helper untouched), security (tightens OFFSEC-015 org isolation for non-root senders — a child can no longer mis-scope a broadcast to its own subtree), performance (drops one carried column; same recursion cost).

No backwards-compat shim / dead code added: confirmed — the buggy SQL is replaced outright, no dual-path shim, no dead code. The unrelated dead-struct removal from staging #2090 was deliberately NOT carried.

Memory/saved-feedback consulted: yes — feedback_verify_real_artifact_not_proxy_metric (added a real-Postgres test rather than trusting the sqlmock proxy that cannot execute the CTE); feedback_build_integration_tag_before_push (vetted with -tags=integration before push); feedback_check_for_parallel_work_before_fix_pr (verified the stale salvage branch carried only the same org-root hunk, no other parallel work lost).

Closes #1959.

fix(broadcast): resolve true org root in CTE, not sender's own id (#1959) ... 47a6881d16

The org-root recursive CTE in workspace_broadcast.go pinned `id AS root_id`
to the SENDER's own id at the anchor and carried it unchanged up the
parent_id chain. The final `SELECT root_id ... WHERE parent_id IS NULL`
therefore returned the sender's id, not the actual org root — so a
NON-root sender resolved ITSELF as the org root, scoping the broadcast to
the wrong subtree (the OFFSEC-015 org-isolation guarantee was correct for
root senders but wrong for any child workspace).

Fix: drop the bogus carried `root_id` column and select the id of the
row whose parent_id IS NULL (the true topmost ancestor). The walk
direction (JOIN org_chain c ON w.id = c.parent_id) was already correct.

Trace (leaf->mid->root): now resolves leaf and mid to root, root to
itself.

Adds a REAL Postgres integration test (build tag `integration`,
Handlers Postgres Integration CI) that seeds a 3-level chain and asserts
every node resolves to the true root — sqlmock cannot execute the CTE so
the existing unit tests could not catch this. Original staging reference:
closed PR #2090 (verified + applied cleanly, org-root hunk only).

QA approved (#2105). Verified: real-Postgres integration test (workspace_broadcast_org_root_integration_test.go) seeds a 3-level org chain and asserts every node — including the deep non-root leaf — resolves to the true null-parent root. This is the regression gate the sqlmock unit tests structurally could not provide (sqlmock cannot execute the recursive CTE). Plain + integration-tagged builds green, full handler suite green.

Security approved (#2105). This fix TIGHTENS OFFSEC-015 org isolation: previously a non-root sender resolved itself as the org root, letting a child workspace mis-scope a broadcast to its own subtree (wrong recipient set). The corrected CTE resolves to the true null-parent ancestor, restoring tenant-correct scoping for all senders. No new query surface, no auth change, parameterized query unchanged ($1 binding). No secrets, no injection vector introduced.
