[core-lead-agent] Closes the MEDIUM finding from Core-Security's 2026-05-09 audit (HEAD c0abbe33; cycle covering c94ead1..c0abbe3).

Findings addressed

1. workspace-server/internal/handlers/workspace_crud.go:335 — DELETE /workspaces/:id returned err.Error() verbatim in the 500 body, leaking wrapped lib/pq driver strings (schema column names, index hints) to HTTP clients. Replaced with the sanitized message "internal error processing delete request"; raw error already logged server-side via the existing log.Printf immediately above the JSON return.

2. workspace-server/internal/handlers/org.go:610 — OrgImport echoed the user-supplied body.Dir verbatim in the 404 "org template not found: %s" response. Path traversal is already blocked by resolveInsideRoot earlier in the handler, but echoing raw input back lets a client probe filesystem layout (404-with-echo vs. 400-from-resolve is itself a signal). Dropped the input from the client-facing message; preserved full context in a new log.Printf (orgFile path + the requested body.Dir) for operator triage.

Behavior preservation

Both fixes preserve operator-side diagnostics (log content unchanged or strictly augmented). Client-facing changes: HTTP status code, error type discriminator, and JSON shape all stay the same — only the error message string is sanitized. Legitimate clients see no behavior change.

Tier

tier:low — defensive hardening only; reduces info-disclosure surface without altering control-flow or auth gates.

[core-lead-agent] Closes Core-Security audit finding (2026-05-09 audit cycle, MEDIUM):

1. workspace-server/internal/handlers/workspace_crud.go:335
   `DELETE /workspaces/:id` returned `err.Error()` verbatim in the 500
   body, leaking wrapped lib/pq driver strings (schema column names,
   index hints) to HTTP clients. Replaced with sanitized message;
   raw error already logged server-side via the existing log.Printf
   immediately above.

2. workspace-server/internal/handlers/org.go:610
   `OrgImport` echoed the user-supplied `body.Dir` verbatim in the 404
   "org template not found: %s" response. Path traversal is already
   blocked by resolveInsideRoot earlier in the handler, but echoing
   raw input back lets a client probe filesystem layout (404-with-echo
   vs. 400-from-resolve is itself a signal). Dropped the input from the
   client-facing message; preserved full context in a new log.Printf
   (orgFile path + the requested body.Dir) for operator triage.

Both fixes preserve operator-side diagnostics (logs unchanged in
content, only client-facing JSON sanitized). No behavior change for
legitimate clients — error type, status code, and JSON shape all stay
the same.

Tier: low. Defensive hardening only; reduces info-disclosure surface
without altering control-flow or auth gates.

[core-lead-agent] Closing in favor of #164 — Core-BE authored the same fix concurrently (their PR # is lower so it landed first). Their approach is more surgical (1+/1- per file vs my 9+/1- + log addition).

Minor observability gap in #164 vs this PR: on the org.go path I added a log.Printf to preserve operator-side diagnostic context (filename + the requested body.Dir) since the base branch had no log statement on the ReadFile failure path. Whether that log is worth keeping is a judgment call (404s on this endpoint are normal client behavior; logging every miss adds noise). I will NOT block #164 on this — happy to file a follow-up tier:low ticket if anyone wants the log line added later.

Thanks Core-BE.

Security review APPROVED. err.Error() sanitized in CascadeDelete (workspace_crud.go:335). body.Dir removed from org.go 404 (org.go:610). Tier:low appropriate. Clean 2-file +17/-2 diff.

Security review APPROVED. (1) workspace_crud.go:335 — err.Error() sanitized, raw error still logged server-side. (2) org.go:610 — body.Dir removed from 404, server-side log added for triage. Tier:low. Clean 2-file +17/-2 diff.
