From 7f5d83d05ad522399fc8b144d13d3803eba332fa Mon Sep 17 00:00:00 2001 From: FENG <223868679+MakerFlyFly@users.noreply.github.com> Date: Mon, 26 Oct 2026 04:57:12 +0000 Subject: [PATCH 1/4] feat(tools/discourse): list recent category activity Projects using Discourse need to discover category discussions before fetching individual topics. Resolve category IDs and catalog paths, then read explicit activity-ordered lists through the existing GET client. Filter on bumped_at without substituting the last-message timestamp. Deduplicate matches and look ahead for an additional match so truncation reports evidence rather than assuming that another page contains results. Fail incomplete reads through the existing CLI error channel, and keep the adapter partial until the remaining archive operations are available.

Missing pin evidence must not be replaced by the output default when deciding the cutoff. Keep category metadata separate from slug matching so an empty or unusable slug does not block numeric ID reads or unrelated selections. Resolve bare slugs only at the catalog root, requiring full ancestry or a numeric ID for subcategories and incomplete catalogs. Retain evidence-based truncation and the integer-conversion error channel. Add regressions and clarify the supported CLI behavior.

Treat continuations as signals while rebuilding every request with the fixed category and activity order. Keep whole-page validation and exact truncation, consolidate regressions, and clarify that pinned category topics count toward the result limit.

From c2805481f4635aaf9aa5807eafab2bb51d3714ac Mon Sep 17 00:00:00 2001 From: FENG <223868679+MakerFlyFly@users.noreply.github.com> Date: Mon, 26 Oct 2026 12:50:57 +0000 Subject: [PATCH 4/4] fix(tools/discourse): accept rooted category paths Resolve category paths against the configured forum without duplicating its base path. Keep full URL boundaries and reject protocol-relative references before any request. Clarify unsupported list-view suffixes and cover rooted paths on root and subfolder installations.
