chore: easy-issue sweep 2026-05-11

[mvillmow]

Summary

Bundled easy-issue sweep across documentation, CI hardening, and small fixes per
the 2026-05-11 ecosystem-wide sweep. 50-LoC-per-issue cap respected; medium/hard
items (full openapi examples, devcontainer split, request-body validation tests,
ASAN preset, etc.) deferred and listed as BLOCKED below.

• Closes Document approved model assignments for L0-L3 in CLAUDE.md #153 — CLAUDE.md HMAS L0–L3 model-tier table
• Closes Document agamemnon/ Python package structure in CLAUDE.md #110 — CLAUDE.md describes the agamemnon/ Python sub-package layout, deps, tasks
• Closes OpenAPI spec has no servers entry for production/Tailscale URL #146 — openapi.yaml adds parameterized Tailscale servers entry
• Closes Chaos endpoint silently accepts body content — document or reject it #191 — openapi.yaml documents that POST /v1/chaos/{type} body is silently ignored

Verified ALREADY-DONE (closes via merge)

• Closes Document /v1/ API contract in README.md #335 — README has full API Documentation (line 38) + API Endpoints (line 92+) covering /v1/
• Closes Link AGENTS.md from README.md for discoverability #150 — README line 20 already links AGENTS.md (See [AGENTS.md](AGENTS.md) for multi-agent handoff protocols.)
• Closes Remove maestro_client.py from orchestration (already deleted in Keystone) #116 — find . -name 'maestro_client*' returns nothing; file is fully removed
• Closes Pin Gitleaks to block-on-failure instead of continue-on-error #254 — _required.yml calls gitleaks with --exit-code 1 and contains no continue-on-error: true (in fact lines 215–229 forbid it repo-wide)
• Closes Move store.cpp into library target to fix test linkage #181 — src/store.cpp is in the library target via cmake/SourcesAndHeaders.cmake:9 and CMakeLists.txt:83

• Closes [MINOR] §5: No request body size limit on HTTP routes (potential DoS) #221 — src/server_main.cpp:133 calls set_payload_max_length(SERVER_REQUEST_SIZE_LIMIT_MB * 1MB) (default 4MB); src/routes.cpp:231 also enforces kMaxBodyBytes

BLOCKED (>50 LoC or external/structural — not in scope for sweep)

• Add response example objects to openapi.yaml for Agent, Team, Task #147 — Add response examples to openapi.yaml for Agent/Team/Task/Fault: requires 4 representative payloads, easily >50 LoC of YAML
• [MINOR] §6: routes.cpp lambda capture of raw Store* is also present in production code #220 — Add ASAN/UBSAN preset to enforce lambda capture invariant: needs new CMake preset + sanitizer build matrix
• [MINOR] §5: update_task does not validate task belongs to team_id before update #222 — Make Store::get_task reject empty team_id: requires test additions and a Store API decision
• Pin apt package versions in Dockerfile to avoid non-reproducible builds #319 — Pin every apt package version in Dockerfile: long-lived version pins create their own maintenance debt and need a tested set
• [MINOR] Add devcontainer Dockerfile for development (separate from production) #327 — Devcontainer Dockerfile separation: new file + multi-stage refactor
• Add CHANGELOG.md update step to pre-commit hook or CI check #135 — CHANGELOG-update CI/pre-commit gate: design choice (pre-commit vs CI vs PR-template) needs scoping

Skipped (external / process / future-dated)

• Add first versioned CHANGELOG block when v0.1.0 tag is cut #136 — First versioned CHANGELOG block: only triggered when v0.1.0 tag is cut
• README: document /v1/workflows endpoint once implemented #138 — README /v1/workflows: handler still returns []; document once implemented
• Verify Renovate GitHub App is installed on HomericIntelligence org #250 — Verify Renovate App is installed: org-admin task, not a code change
• Expand .gitleaks.toml allowlist based on periodic false-positive audit #268 — Quarterly gitleaks-allowlist review: process item, not a code change
• Create GitHub Projects board and link to ROADMAP.md #309 — Create GitHub Projects board: external admin task
• Register PyPI pending publisher for HomericIntelligence-Agamemnon #13 — Register PyPI pending publisher: external admin task (already documented in RELEASING.md)

Test plan

• CI green on chore/easy-sweep-2026-05-11
• actions/checkout and actions/cache@v5 SHAs resolve correctly in _required.yml
• gitleaks step succeeds (SHA256 matches published checksum)
• just coverage runs after a clean checkout via the new deps-coverage chain
• ./scripts/check-release-readiness.sh 0.1.0 cleanly fails on a host without GPG, passes with one configured
• Spectral OpenAPI lint: pre-existing failure on main (Could not read ruleset at .../@stoplight/spectral-openapi) — not introduced by this sweep, leave for separate PR
