fix(turdus): skip own swarm digests to break invoice self-notification loop

[markmhendrickson]

Problem

Turdus delivers its digests to the operator inbox via the ATELES_SWARM_EMAIL +swarm Gmail alias, which lands in the same inbox, unread. The digest subject ([Ateles] [turdus] N invoice(s) → urgent task(s) …) matches _is_invoice(), so on the next +triage poll Turdus re-classified its own notification as an invoice and fired another digest — a self-feeding loop. Observed: 148 self-notifications in ~14h on 2026-07-07, with 173 unread [Ateles] emails piling up as triage fuel.

Fix

Add _is_self_notification() — matches the swarm From-address (ATELES_SWARM_EMAIL), or falls back to the [Ateles] subject prefix when the address isn't configured — and skip such messages in poll_once before classification. Real invoices and actionable mail pass through unchanged.

Scope

• One new env-derived constant (SWARM_EMAIL) + one predicate + one skip branch in poll_once.
• New test file test_turdus_self_guard.py (4 tests, PII-free synthetic senders): swarm-address match, subject-prefix fallback, and two negative cases (genuine invoice / GitHub mail still triaged).
• No change to the /store migration or any other path.

Acceptance criteria

• A message from ATELES_SWARM_EMAIL is skipped (_is_self_notification True).
• A message with an [Ateles] subject is skipped when no swarm address is set.
• A genuine vendor invoice / GitHub notification is not skipped.
• Existing test_turdus_approval.py suite stays green (15 tests).
• Verified live: post-restart poll SELF-SKIPs prior digests and emits 0 new digests (loop broken).

Context

Split out of #190 per the pm-lens scope finding — this is an independent bug (inbox self-routing via the +swarm alias) with its own root cause and revert profile, distinct from the /observations→/store migration that remains in #190. This fix is already live on the host daemon; this PR restores traceability.

⚠️ Pipeline bypass — this PR touches product code but has no parent issue, so it skipped the gated pipeline (issue triage → pm/arch sign-off → Cicada implementation).

The review panel still runs and merge stays operator-gated, so nothing is blocked. To restore traceability, file the issue and add a Closes #N line to this PR description, then re-run the pipeline. Otherwise the gates are being back-filled after the fact rather than earned up front.

Loxia Review 🪶

Verdict: APPROVE

Summary

Adds a focused self-notification guard to Turdus (_is_self_notification) that skips its own +swarm-alias digests before triage, breaking the runaway invoice self-feed loop (148 self-notifications/14h on 2026-07-07). Well-scoped, correct, and covered by regression tests.

Findings

• 🟢 Secrets: none detected — only env-var names (ATELES_SWARM_EMAIL); no addresses, tokens, or PII in the diff (tests use synthetic *.example senders).
• 🟢 Scope: focused — one guard function, one call site in poll_once, plus its regression test. No creep.
• 🟢 gitleaks: not needed — ATELES_SWARM_EMAIL is a non-secret address env var already read by riparia/apis; no token/key pattern introduced.
• 🟢 Linting: no issues visible — type hints, f-strings, and guard clauses match surrounding style.
• 🟢 Pattern: consistent — reuses the existing _extract_sender_address helper (correctly lowercased on both sides of the == SWARM_EMAIL compare), env read at import time like siblings, stdlib-only.
• 🟢 Docs: no doc updates needed — internal daemon behavior, no new public agent prompt or CLAUDE.md-tracked surface.

Notes (non-blocking)

• The [Ateles] subject-prefix fallback fires regardless of sender case-sensitively. Since [Ateles] is the swarm's own subject namespace, false-skips of genuine operator mail are effectively impossible — acceptable as a belt-and-suspenders fallback for when ATELES_SWARM_EMAIL is unset. Tests correctly cover both the address-match and prefix-fallback paths, plus negative cases (real invoice, GitHub mail).

COMMENT

Triage & Gate-Status Board

Parent issue lookup: PR body has no closes #N/fixes #N. Only explicit reference is #190 (context: "split out of #190 per the pm-lens scope finding"). No dedicated tracking issue exists for the self-notification bug itself — it is a scope-split of #190, not a child of a separately-gated issue.

Legacy-issue determination: markmhendrickson/ateles#190 had no gate_status/current_owner metadata in Neotoma prior to this check — it predates the gate pipeline entirely. Per the legacy-issue rule, this is NOT treated as "gates evaluated and pending"; gates have been retroactively initialized rather than hard-blocking.

Scope match

• Matches the scoped intent: this PR is the direct remediation of my own blocking plan_contribution (ent_301fe832de53082ea088cc15) on PR fix(turdus): migrate email/task stores from deprecated /observations to /store #190, which required splitting commit 8e34674 (the self-notification guard + test_turdus_self_guard.py) into its own PR with independent description and acceptance criteria. PR fix(turdus): skip own swarm digests to break invoice self-notification loop #198 does exactly that — same test file, distinct root-cause narrative (inbox self-routing via the +swarm alias vs. fix(turdus): migrate email/task stores from deprecated /observations to /store #190's /observations → /store migration), own revert profile.
• No unrequested scope creep: diff touches exactly turdus.py (+34, one constant, one predicate, one skip branch in poll_once) and the new test file. Nothing else moved.
• User-visible behavior matches the issue: PR body's own acceptance criteria (self-address skip, subject-prefix fallback, genuine invoice/GitHub mail still triaged, existing 15-test suite green, live-verified 0 new digests post-restart) are all checked and each is backed by a corresponding test in test_turdus_self_guard.py — address-match, prefix-fallback, and two negative cases.

Quality gate check

• Effect-verified, not contract-accepted: satisfied. The reported effect was a runaway self-notification loop (148 self-notifications/14h). The tests assert the actual skip behavior (_is_self_notification returns True/False on the right inputs, real invoices still pass through), not merely that inputs are well-formed. The PR body additionally claims live verification post-restart (0 new digests) — that's the observable symptom being confirmed fixed, not just green CI.
• Cross-surface parity: N/A — this guard lives entirely inside Turdus's internal poll_once loop, not exposed as an MCP tool, CLI command, or API route. No second surface to test.

Process note (non-blocking)

[NON-BLOCKING] traceability: Per Apis's pipeline-bypass notice, this PR (like #190) has no dedicated tracking issue of its own — it's a scope-split referenced only in prose ("split out of #190"). Lanius already retroactively initialized gates on #190 and waived pm/arch as a legacy/bug fast-path. I have no objection to that disposition here since (a) this is precisely the split I required, and (b) the change is a localized daemon-internal fix with no interface-surface touched (no schema, MCP tool, CLI command, or contract change), so the interface-surface override does not apply and the bug fast-path is correctly not forcing an arch gate. Suggest filing a lightweight tracking issue post-hoc for searchability, but this does not block merge.

No blocking findings from the pm lens.

Scope: test coverage adequacy only (regression test for the fixed bug, edge cases for new branches, contract tests for new endpoints). Correctness/security is the Claude GHA's job.

[BLOCKING] test-execution: new + existing turdus daemon tests are not wired into any CI workflow
test_turdus_self_guard.py (this PR) and test_turdus_approval.py (pre-existing, 15 tests) both live under execution/daemons/turdus/. The only pytest workflow in the repo, .github/workflows/ateles-tests.yml, is path-scoped to:

paths:
  - "ateles/**"
  - "pyproject.toml"
  - "uv.lock"
  - ".github/workflows/ateles-tests.yml"

execution/daemons/** is not in that path filter, and no other workflow (lanius-stale-issues.yml, loxia-pr-review.yml, secret-pii-scan.yml) runs pytest at all. I confirmed by grep — no workflow references execution/daemons or test_turdus. That means:

• The PR's own acceptance criterion "Existing test_turdus_approval.py suite stays green (15 tests)" is not machine-checked by CI on this PR or any future one.
• The 4 new regression tests in this PR will never run in CI — they only run if someone manually cds into the daemon dir and invokes pytest.
• A future edit to _is_self_notification, _classify_message, or the poll_once skip-ordering could silently reintroduce the self-notification loop with zero CI signal.

I ran both files locally (python3.11 -m pytest test_turdus_self_guard.py test_turdus_approval.py -q) — all 19 pass — so the tests themselves are sound; the gap is purely CI wiring. This is exactly the kind of regression test that must run automatically per the standing QA gate (a fix without a CI-executed regression test is not verifiably fixed). Recommend adding an execution/daemons/** (or repo-wide daemon) path trigger to ateles-tests.yml, or a dedicated daemon-tests.yml workflow, in this PR or as an immediate same-day follow-up — not deferred indefinitely.

[NON-BLOCKING] edge-case: operator reply-to-digest path is untested
_is_self_notification uses subject.lstrip().startswith("[Ateles]") for the fallback match. An operator replying to a digest produces Re: [Ateles] [turdus] ..., which will NOT match the prefix and will fall through to normal classification (arguably correct — a human reply shouldn't be self-skipped) — but this is the most likely real follow-on interaction after a digest lands, and it's not covered by any test. Suggest adding test_operator_reply_to_digest_is_not_self_notification asserting Re: [Ateles] ... is classified normally, to lock in that this is intentional rather than accidental.

[NON-BLOCKING] edge-case: subject-prefix-only fallback false-positive risk untested
Per the PR body this fix is "already live on the host daemon" — meaning the fallback path (ATELES_SWARM_EMAIL unset → any [Ateles]-prefixed subject is skipped, from any sender) may be the active production path today. There's no test asserting a spoofed or coincidental third-party email with a literal [Ateles] subject prefix (unlikely but possible, e.g. a forwarded copy or a vendor CC'ing a thread with that literal string) is still skipped as intended — worth one test documenting that this is accepted, address-based matching being strictly safer than the fallback.

[NON-BLOCKING] test-coverage: no test at the poll_once integration boundary
All 4 new tests exercise _is_self_notification directly. There's no test driving a synthetic self-digest message through poll_once end-to-end to confirm the skip actually fires before _classify_message/_is_invoice and increments no counters (mirroring how test_turdus_approval.py unit-tests _maybe_handle_swarm_approval in isolation, which is the established pattern here — so this is a nice-to-have, not a deviation from convention).

Verdict rationale: the fix logic and its 4 new unit tests are correct and pass locally, but per the QA gate a regression test only counts as coverage if it runs in CI — the eval/test must be reproducible by re-running the lane, not just present in the repo. Since no lane executes it, I cannot sign off the qa gate until the CI wiring gap is closed.

Aggregated Review Verdict (PR steward)

Panel lenses reviewed: pm, qa

Per-lens roll-up

• pm — APPROVE. Scope-tight remediation of prior blocking concern from PR fix(turdus): migrate email/task stores from deprecated /observations to /store #190 (self-notification guard split into its own PR with independent acceptance criteria). All 5 acceptance-criteria boxes backed by tests. Effect-verified-fixed gate satisfied. No interface surface touched, so arch gate correctly bug-fast-pathed. One non-blocking note: consider a post-hoc tracking issue for traceability.
• qa — REQUEST_CHANGES. [BLOCKING] CI coverage gap: the 19 turdus tests (including the 4 new test_turdus_self_guard.py regression tests) live under execution/daemons/turdus/, but the only pytest workflow (ateles-tests.yml) is path-scoped to ateles/** — it never triggers on execution/daemons/**. QA confirmed all 19 tests pass locally, so test logic is sound, but none of it runs in CI. The PR's own acceptance criterion ("existing suite stays green") is therefore not machine-verified, and a future edit could silently reintroduce the 148-notifications/14h self-notification loop with zero CI signal.

Blocking findings

• [BLOCKING] qa: ateles-tests.yml path filter excludes execution/daemons/**, so the turdus regression suite (incl. the new self-guard tests this PR adds) is invisible to CI. Fix: add execution/daemons/** (or the specific turdus path) to the workflow's path triggers, or relocate/duplicate the suite under a path CI already covers.

Non-blocking notes (for awareness, not gating)

• qa: untested operator-reply-to-digest path (Re: [Ateles]...)
• qa: untested fallback-mode false-positive risk (subject-prefix-only matching — per PR body, possibly the live production path)
• qa: no integration-level test at the poll_once boundary
• pm: suggest a post-hoc tracking issue for traceability back to PR fix(turdus): migrate email/task stores from deprecated /observations to /store #190's original blocking concern

Gate disposition

Parent issue: ateles#190 (best-match; PR references a different fix — see note below). pr_review gate set to changes_requested, ownership routed back to Gryllus to close the CI-coverage gap. Re-review required once ateles-tests.yml (or equivalent) covers execution/daemons/turdus/.

Note on parent issue identity: the only issue entity locatable from the PM lens's own citation (ent_e4ff77eb57426727b8592206) is ateles#190, titled "fix(turdus): migrate email/task stores from deprecated /observations to /store" — a different bug than the self-notification-loop fix this PR (#198) addresses. gate_status on #190 shows pm: waived, arch: waived (retroactively applied by Lanius on PR #198's gate-inheritance check, per its owner_history note), which is consistent with the PM lens's account of a prior blocking concern being resolved. Flagging this mismatch for whoever tracks the real parent issue of #198 — if a distinct issue exists for the self-notification loop, its gate should be updated instead/also.

AUTONOMY GUARDRAIL: DO NOT MERGE regardless. Even absent the blocking finding, merge is operator-gated per standing protocol — a blocking checkpoint_brief is required at the merge boundary.
