Description of the idea or improvement

Add /copilot history with no arguments, no model and no mutation. Publish one localized correlated reply containing at most ten recent supported command operations in the exact issue or PR conversation, ordered by source comment identity, excluding the current request and history-query replies. Reuse trusted bot-owned correlated semantic receipts and existing command parsing. Show operation, honest outcome, source request and receipt links, and only validated structured commit evidence when available. Never infer success from a human command, raw Result.steps or untrusted prose. Deduplicate replayed operations by exact target plus correlation identity. Preserve unavailable/partial states when comment pagination or reads are incomplete; do not claim a global audit log. Do not echo arbitrary arguments, prompts, secrets or raw errors. No new persistence store or configuration flag; deterministic English/Spanish rendering and existing publication reconciler.

Current limitations or challenges

Long dogfooding conversations accumulate commands, retries, receipts and branch effects. A developer currently has to reconstruct them manually. The feature should summarize evidence already retained by the Action without duplicating notifications or overstating old, incomplete or forged records.

Expected impact

After several real operations, a developer can inspect the last ten evidenced operations and follow each request/receipt safely. Replays reuse one history reply; new queries receive their own response. Distinct issue/PR targets, malformed/foreign markers, unsupported commands, incomplete reads, duplicate receipts, pending/failure/success and unsafe content are covered. Plan at least 28 distinct risk-derived cases plus documentation, catalog and executable acceptance. Existing operational and authorization behavior stays intact.
