Do not broaden the task, +rewrite unrelated files, or silently repair adjacent issues. + +Use semantic code search before wandering through unfamiliar code. Use exact +text search only when the symbol or literal is already known.

State the problem and result in plain language. +2. Define specialized terms at first use. +3. Give one concrete example, counterexample, or failure case. +4. Explain the mechanism before naming abstractions. +5. Add exact technical detail, evidence, and limitations after the plain account. +6. Remove any sentence that only repeats, markets, congratulates, or narrates the + agent's process. + +Plain language must not erase uncertainty or precision. If the simple account +cannot be reconciled with the implementation or data, the explanation is not +finished. + +## Claim and evidence boundaries + +Label substantive claims using one of these epistemic states: + +- `OBSERVED`: directly measured or read from a cited artifact. +- `INFERRED`: follows from observations but was not directly measured. +- `HYPOTHESIZED`: testable explanation not yet established. +- `PROPOSED`: intended future change or design. +- `UNKNOWN`: provenance is missing or verification failed. + +Never turn an inference into an observation during summarization. Never invent a +citation, run, command, result, implementation detail, or source location. Code +claims need a commit plus file/symbol reference. Result claims need an immutable +artifact or run identifier. External claims need a primary source actually +opened by the reviewer. If the source cannot be checked, say `UNKNOWN`. + +Keep negative results, exclusions, failed runs, contradictory evidence, and +changes from the preregistered or stated plan visible.

Use `ANALYZED` +for inspection without reproduction. Deterministic runs require exact agreement; +stochastic runs require a justified tolerance declared before comparison. + +The empirical reviewer must be a fresh review pass, separate from the authoring +pass.

This policy intentionally stays at that bound and handles +the `Retry-After` response instead of relying on burst behavior. + +## Exact action-time authorization steps + +Stop if any screen requests more permission than this document lists. + +### 0. Preconditions + +1. Merge and protect the policy only after human review; do not install from a + mutable draft branch. +2. Deploy the broker receiver, queue, worker, idempotency table, secret store, + and `#integration-sandbox` route with message sending disabled. +3. Verify HMAC failure, duplicate delivery, unknown action, secret-shaped field, + external evidence link, Slack markup, queue retry, and dead-letter tests. +4. Create the seven Slack channels, decide which are private, and copy each + channel ID from Slack. Do not put channel IDs or tokens in source code. + +### 1. Create and authorize the Slack app + +1. As a Slack workspace owner, open **Slack API → Your Apps → Create New App → + From an app manifest**. +2. Select the Perseus workspace and paste `slack-app-manifest.yaml`. +3. On the preview, verify exactly one bot scope: `chat:write`. Confirm that + user scopes, Events API, interactivity, incoming webhooks, Socket Mode, and + `chat:write.public` are absent. Create the app. +4. Open **OAuth & Permissions → Install to Workspace**. If workspace app + approval is enabled, submit the request to a workspace owner. +5. On Slack's OAuth consent screen, verify the app can only send messages as its + bot. Click **Allow**. This is the only Slack OAuth grant. +6. Transfer the resulting bot token directly into the notifier's AWS Secrets + Manager secret. Do not copy it into GitHub, a terminal transcript, Slack, + email, or a document. Restrict the task role to `secretsmanager:GetSecretValue` + for this single secret and KMS decrypt for its single key. +7. In each permitted channel, run `/invite @Perseus Engineering Notifier`. + Because the app lacks `chat:write.public`, membership is its channel boundary. +8. From the broker, call Slack `auth.test`, then send one synthetic message to + `#integration-sandbox`. Do not enable production routing yet. +9. Leave token rotation disabled during the sandbox unless the refresh worker + is already deployed. After a 24-hour refresh test, enable rotation once, + store both access and refresh tokens atomically, refresh before 12 hours, and + retain at most Slack's two active token limit. + +This one-workspace internal app needs no user token and no OAuth redirect +handler. If the app is ever distributed to another workspace, implement OAuth +V2 with state validation, a controlled HTTPS redirect URI, per-workspace token +storage, deletion, and rotation before adding the second workspace. + +### 2. Create and authorize the GitHub App + +1. As an `efficientsystemsinc` owner, open GitHub **Settings → Developer + settings → GitHub Apps → New GitHub App**, with the organization selected as + owner. +2. Set the name to `Perseus Engineering Notifier`, the homepage to this policy, + and the webhook URL to the deployed broker HTTPS endpoint. +3. Generate a random webhook secret in the production secret manager. Enter the + same value into GitHub's **Webhook secret** field without logging it. Leave + SSL verification enabled and Webhooks active. +4. Disable user authorization. Leave callback and setup URLs empty. Choose + **Only on this account**; this is a private installation, not a Marketplace app. +5. Set repository permissions to Actions **Read**, Checks **Read**, Pull + requests **Read**, Metadata **Read**. Set organization Projects to **Read**. + Verify every other permission is **No access**. +6. Subscribe only to the seven events in the GitHub checklist above. Add + `projects_v2` only if project lifecycle notifications are approved. +7. Create the app. Generate one private key and import the PEM directly into + AWS Secrets Manager. Delete the downloaded local copy after verifying the + stored checksum. Record the App ID and installation ID as non-secret config. +8. Open **Install App → efficientsystemsinc → Only select repositories**. Pilot + with `.github`, `perseus`, `perseus-bench`, and `perseus-bio`; do not choose + all repositories until the event and data audit passes. +9. Deliver GitHub's `ping`, confirm valid signature and `202`, then redeliver the + same delivery and confirm it is deduplicated. Test a synthetic PR/check in a + fixture repository before production routing. + +No GitHub user OAuth grant or personal access token is required. The broker +creates short-lived installation tokens from the App ID and private key only +when an API lookup is necessary. + +### 3. Enable routing gradually + +1. Enable `#eng-prs` for the fixture repository for 24 hours. +2. Add `#eng-ci` failures and recovery; check duplicate suppression. +3. Add deterministic evidence-gate outcomes. Keep model review results marked + advisory. +4. Add agent-activity summaries and manually inspect every field for one week. +5. Add Project digests last because Projects webhook schemas are public preview. +6. Expand repository access only after the audit shows no raw or secret-bearing + data, no unexpected action, and acceptable message volume. +7. Record app owners, incident contact, credential rotation dates, and uninstall + procedure in the private operations runbook. + +### 4. Optional official GitHub-for-Slack alternative + +If speed is chosen over the narrower permission model: + +1. A Slack owner installs the official GitHub app and reviews its Slack scopes. +2. A GitHub organization owner installs it on **selected repositories**, not all. +3. Every member who needs mentions runs `/github signin` and reviews the account + link. +4. In `#eng-prs`, subscribe only to pulls and reviews; in `#eng-ci`, subscribe to + the named workflow with event and branch filters. Keep comments and all-branch + commits off. +5. Do not install the custom notifier at the same time. + +The authorization review must explicitly accept that the official app documents +GitHub write access to Actions, issues, deployments, and pull requests. It is not +the least-privilege recommendation in this design. + +## Failure and revocation + +1. Disable production routing and preserve only delivery IDs and counts. +2. Revoke the exposed Slack token or uninstall the app; rotate the GitHub webhook + secret or add a new private key. +3. Deploy the replacement credential before deleting the old GitHub key so there + is an overlap window. +4. Redeliver missed GitHub App webhooks explicitly after recovery; GitHub does + not automatically redeliver failures. +5. Delete workspace token records, queued bodies, and backups when the Slack app + is uninstalled. + +## Primary references + +- [GitHub App permission
