From 7d263ee8c9898ec90adf247a42eee5c3d9b36c4d Mon Sep 17 00:00:00 2001 From: tzhouam Date: Mon, 28 Sep 2026 20:10:06 +0800 Subject: [PATCH] Add the knowledge merge flow, snapshot activation, release sweep and scheduler Completes the knowledge service's lifecycle after the gate. - merge: the publisher's signed acks advance a change set through pr_requested, pr_open, verdict_posted, queued and merged. The service signs the kb-gate verdict for the PR's exact head (patch manifest, per-block and consistency judgements) and posts it through an outbox post_verdict item. It issues `enqueue` only after the PR-stage kb-gate status succeeded, with at most one queued knowledge PR per repository. A head change after signing goes to people; a PR closed unmerged is recorded; merged retirements become purge candidates for the next release. pause_open_prs issues dequeue+draft items. - activate: every main SHA becomes an immutable snapshot (knowledge tree plus MANIFEST). It is verified (loads as a KnowledgeView, no tree issues, every _routes.yaml loads) and then activated by an atomic symlink swap; rollback and retention (last 10 plus the active one) are included. A snapshot that does not load is an ActivationError and `active` is left untouched. - sweep: triggered by a release (the first one seen only records the baseline) or the fallback interval. T1 reports structural issues to people, and its only automatic fix, missing index links, is now accepted by L1 for existing unlisted pages. T2/T3 asks the generator per rule page, with the release diff of the paths that page owns, to keep, edit, replace or retire each active rule. Rules retired a release ago are purged. Every page is its own gated change set, and a sweep-wide circuit breaker sends all of them to people. - scheduler (`kb serve`): holds the lease for its lifetime. Each tick it re-signs the control record and hold list, applies acks, advances merges and runs intake and sweeps per repository (isolated from each other), and activates a new main. Two knowledge PRs closed unmerged by people within 24 hours pause the repository and dequeue its open PRs. - robustness: each change set records the outbox item it waits on; nothing is re-issued while that item is unexpired, and an ack applies only to that item from its matching state. A rollback pins `active` until main moves on. Snapshot activation re-hashes every manifest entry. Sweep progress is tracked per page: a failed evaluation is retried (people get it after 3 attempts) and the baseline advances only once every page is settled. Sweep change sets are held until the sweep settles, so the sweep-wide breaker sees every attempt. Activation, rollback and the scheduler's pin check share an interprocess lock. `kb resume` returns paused PRs to re-signing, and each tick re-publishes anything still gated. The ledger migrates v1 to v2 in place. - steps and playbooks kb-merge, kb-sweep and kb-activate (candidate); CLI `kb serve [--once]`, `kb activate`, `kb rollback --to SHA`; `kb pause` also issues pause items for open PRs.
