Evidence

Parents and chain

  • GAR-6453 (Write: Rhododendron roxieanum) — `done`, contains the Writer's full draft as comment `e6668b1f-07d5-480b-a078-b39e66588624` (posted by agent `ade4ade4` at 2026-07-19T23:07:07Z, 10,843 chars) plus a one-line "Draft posted for QA review" pointer.
  • GAR-6465 (this QA task) — `in_progress`, 0 prior comments. The wake description ("Write done but QA never spawned; continue the chain") matches the recovery context; the original article is recoverable from GAR-6453 and was verified here.
  • Saved locally at `/tmp/gar-6465-article-draft.md` for evidence chain.

Deterministic Content QA (against `/root/gw/article-spec.md`)

11UK relevance (UK/Britain/British/nurseries)PASS — strong
12Specificity (months + metric measurements)PASS — 5 month refs (April/May/June/September/October) and cm measurements throughout

Hardiness note (spec-required honesty)

Spec line: "If information is limited, state the uncertainty explicitly rather than fabricating." Quick-care table says "the precise hardiness rating is not established for this species" — explicit hedge, no fabricated H-number. Compliant.

Image-candidate QA

Out of scope for this wake. The wake payload supplies no `PLANT_SLUG=` after image import; image-candidate QA runs at the Publisher stage (image prompt + admin-portal human visual review). I did sanity-check `gw-chatgpt-image status roxieanum` (returns "no encyclopedia article/plant" — expected, the article has not yet been published into the publisher's plant registry; this is the Publisher's ingestion job, not a QA defect).

Anti-loop note

This is the first QA heartbeat on GAR-6465 (0 prior comments). No repeated verdict risk.

Not in QA scope (per skill)

  • I did not write, generate, stamp `vision_status=checked`, regenerate the image, or publish.
  • The Publisher child issue and the human visual review in `/gw-admin-portal` remain the next links in the chain.

Pests and Diseases

ProblemSymptomsManagement
Vine weevilNotched leaf margins and wilting plants caused by grubs feeding on roots in the pot or soil.Check new arrivals for grubs and use biological nematodes or systemic insecticides if infested.
Powdery mildewWhite powdery fungal growth on leaves, buds, and shoots, potentially causing distortion.Improve air circulation and apply fungicide only if severe; otherwise tolerate minor infections.
Bud blastFlower buds turn brown, shrivel, and fail to open due to fungal infection or weather stress.Remove and destroy infected buds promptly to prevent spread where practical.
Silver leaf fungusLeaves develop a silvery sheen underneath and stems may show white fruiting bodies at the base.Prune out affected branches well below the infection site and destroy them immediately.
Pieris lacebugSmall white speckling on leaf undersides and black tar-like spots from insect excrement.Encourage natural predators or use horticultural oil sprays during early infestations.
