The Feed Watch

A full feed audit tells you everything wrong with the feed, which on a real catalog is a list nobody reads twice. This loop runs the audit on a cadence and reports only what changed, so a disapproval that appeared overnight is visible instead of buried under 400 known issues.

How to run

1. The current feed export and the channel it targets: Google Shopping, Meta catalog, TikTok catalog, or a marketplace. Requirements differ per channel and a diff across two different channels is meaningless.
2. Channel diagnostics - Merchant Center or the equivalent - if disapprovals already exist.
3. Live product page URLs for a sample, so feed values can be checked against what the storefront actually shows.
4. The ledger, for the previous run's issue set, the watchlist, and suppressions.
5. The severity floor for what gets reported: everything, or only issues that block delivery. Default to delivery-blocking, because that is the set with revenue attached.

Method

1. Confirm the feed is the same feed. Compare row count and channel against last run. A feed that shrank by 30% overnight is the finding - a truncated export produces hundreds of false "newly missing" attributes. Report a large row-count drop as a suspected export failure and stop rather than diffing it.
2. Read the ledger for the prior issue set, watchlist, and active suppressions.
3. Run the audit using the-feed-auditor's method against the stated channel's requirements. Do not substitute a generic attribute list - the required set is channel-specific.
4. On the first run, record the full issue set as the baseline and report it as a backlog, not as breakage. Every issue is "new" on run one. Labelling the backlog as overnight breakage destroys the loop's credibility immediately.
5. Diff into four buckets, which carry different urgency:
   • New - absent last run, present now. This is the loop's whole reason to exist.
   • Resolved - present last run, gone now. Confirms fixes landed.
   • Persistent - present both runs, with a count of consecutive runs.
   • Regressed - resolved in an earlier run, back again. The most important bucket: a regression means a fix does not hold, usually because a template or sync overwrites it.
6. Evaluate the gate: flagged if any new or regressed issue is at or above the severity floor. Persistent issues do not trip the gate - they are already known - but are counted so a growing backlog stays visible.
7. Check price and availability against the live page for every new issue, not just against the feed's internal consistency. A feed that agrees with itself and disagrees with the storefront is the mismatch that gets products disapproved.
8. Group new issues by cause, not by SKU. Fifty SKUs missing GTIN from one supplier import is one problem with one fix, and listing it fifty times hides that. Inherit the-feed-auditor's cleanup-pattern output for this.
9. Never edit products or the feed. Feed and disapproval issues need human diagnosis - a wrong automated fix propagates to every channel reading that feed. Output the work queue for a person.
10. Append to the ledger: feed row count, channel, the full current issue set for the next diff, and which buckets each issue landed in.

Output format

Feed watch verdict: how many new and regressed issues at or above the severity floor, and whether the gate tripped. Or SUSPECTED EXPORT FAILURE with the row-count evidence.

New since last run (grouped by cause, not by SKU)

Regressed: issues that were fixed and came back, with the run they were resolved in and the likely overwrite source.

Resolved: confirmed fixes since last run.

Persistent backlog: count by severity plus consecutive-run count, not the full list.

Live page mismatches: feed value versus storefront value, both stated, for every new mismatch.

Feed integrity: row count this run versus last run, and the channel audited.

Rules

• Never diff a feed whose row count dropped sharply without first reporting a suspected export failure.
• Never diff across two different channels' feeds.
• Never report the first run's backlog as new breakage.
• Never edit a product, a feed row, or a template. Diagnosis and fixes are human work here.
• Never list a shared cause once per affected SKU. Group by cause.
• Never let persistent issues trip the gate - only new and regressed ones.
• Never check price and availability against the feed alone when live page URLs were provided.

Quality check before returning

Before returning the output, verify:

• Row count and channel were compared against last run, and a sharp drop reported as suspected export failure.
• The first run is labelled a baseline backlog, not breakage.
• Every issue landed in exactly one of new, resolved, persistent, or regressed.
• Regressions name the run they were previously resolved in.
• New issues are grouped by cause with SKU counts, not enumerated per SKU.
• New price and availability issues were checked against the live page, with both values stated.
• The gate was evaluated on new and regressed issues only.
• The full current issue set was appended to the ledger for the next diff.

If any check fails, correct it before returning the output.
