996651c6f3 docs(framework): alpha DoD §8 green-checklist + v0.0.39-alpha release notes
All checks were successful
ci/woodpecker/pr/ci Pipeline was successful
ci/woodpecker/push/ci Pipeline was successful
Maps every Constitution-alpha acceptance criterion (DESIGN §8) to its merged
PR, and drafts the Gitea release notes for the v0.0.39-alpha tag. For the Lead
to use when cutting the tag after P5 #605 -> P6 #607 -> aiguide #8 merge.

Refs #606, #542

244290d64d feat(framework): P6 docs + compliance matrix + resident-budget CI (#606)
R9 + R10 of the Constitution alpha (in-repo deliverables):

- framework/CONTRIBUTING.md: layer model, operator-hygiene/PII prohibition,
  dedup rule, resident budget, dual-installer parity rule, adding-a-harness,
  re-contamination rule, harness x gate compliance matrix (hook-parity gap
  marked as tracked-v2), known-limitations (DESIGN §9 residuals), PR checklist.
- check-resident-budget.sh: line-count ceiling over framework-owned resident
  files (CONSTITUTION + AGENTS + each runtime/*/RUNTIME.md), with --self-test;
  replaces the crude inline ci.yml loop. Wired blocking in .woodpecker/ci.yml.

Composer unit test (R9) already runs via pnpm test; verify-sanitized.sh (P1)
already wired. Sanitization + budget + prettier all green.

Remaining for the mission close: aiguide reconcile (separate repo) + the alpha
tag (Lead cuts after full DoD §8 green + all phases merged; P5 #605 pending).

A **general** fleet starts at this floor: the orchestrator (advised by the enhancer)
materializes whatever roles prove necessary over the mission's life. Specialized presets
(coding, research, etc.) seed additional roles up front, but all reduce to the same two-agent
spine plus an on-demand **role library**:
| Role profile | Purpose |
| ------------------- | --------------------------------------------------------------------------------- |
| **orchestrator** | point of contact, flow control, fleet composition (1 per fleet) |

| **code review** | independent code review gate |
| **security review** | security/auth/secret review gate |
| **research** | investigation, synthesis, options analysis |

| **operations** | infra, deploy, health, incident response |

## Decisions of record (2026-06-22, with Jason)
- **Two-agent floor:** every fleet has, at minimum, an **orchestrator** and an **enhancer**.
The orchestrator is the user's point of contact and composes the fleet; the enhancer runs the
continuous-improvement loop (monitor → analyze → remediate → upgrade tools/skills/harness →
file Mosaic Stack bug reports) and **does not code or review**.
- **Role library:** orchestrator, enhancer, coder, code review, security review, research,
board (moonshot/contrarian/technical/business/financial), operations — extensible; the
orchestrator (advised by the enhancer) adds roles as missions demand.
- **Orchestrator chat connector:** the orchestrator is reachable over a user-chosen connector
(tmux now; Telegram/Discord/Matrix/Slack configurable). Validated live: **"Mos" orchestrator
on Discord** via the Claude Code discord channel plugin (w-jarvis).
## Future enhancements (north-star, post-MVP — not on the MVP track)
- **Mosaic Claude Discord Plugin** — a first-party Mosaic Discord connector that properly
implements the basic Discord functions **and native Discord threads**. Threads let a user
separate conversation topics with the orchestrator (the pattern proven by the Hermes agent).
A major enhancement over the current third-party channel plugin; **not required for the MVP**,
but a committed north-star target. `ASSUMPTION:` ships as a Mosaic-owned plugin so the fleet
controls Discord UX (threads, reactions, attachments, per-thread context) end-to-end.
## Assumptions (veto-able)

# F3-m3 — `mosaic update` re-seeds framework + relaunches agents (R13)
- **Issue:** #609 · **Branch:** `feat/f3-m3-update-reseed`
## Gap (found in 0.0.39 production validation)
`mosaic update` installs the new npm CLI but never re-seeds `~/.config/mosaic/` from the package's
bundled `framework/`. So the shipped custom Pi harness (agent-name export + native HB, 0.0.39) stays
DORMANT until a re-seed — operators get the new CLI on a stale framework.
## Implementation
- `update-checker.ts`: `resolveBundledFrameworkRoot()`, `buildReseedCommand()` (install.sh in
`MOSAIC_SYNC_ONLY=1 MOSAIC_INSTALL_MODE=keep` — the P4 data-safe reconcile), `runFrameworkReseed()`,
`readRosterAgentNames()`, `buildRelaunchCommands()` (systemctl --user restart per agent).
- `cli.ts` `update`: after a successful CLI install that includes `@mosaicstack/mosaic`, re-seed the
framework (default-on; `--no-reseed` to skip). Then either `--relaunch` (restart rostered agents) or
print clear guidance to run `mosaic update --relaunch` / `mosaic fleet restart`.
## Flow
`update CLI → re-seed framework (data-safe) → relaunch agents (opt-in)` — closes R13, activates the
native harness for every operator.
## Verification
- 6 new unit tests (reseed command/env, relaunch commands, roster parse, missing-installer guard).
- 19 runtime + 26 launch tests still green; tsc/eslint/prettier clean.
- Data-safety of the sync is already proven (P4 5-fixture matrix + live dragon-lin validation).

# Fleet enhancer role + two-agent floor (#614)
- **Issue:** #614 · **Branch:** `feat/fleet-enhancer-floor` (stacked on #612 `feat/fleet-polish-bundle`)
- **Doctrine:** `docs/fleet/north-star.md` (PR #613) — every fleet = orchestrator + enhancer minimum.
## Changes
- **Presets** (general, coding, research, hybrid): add `enhancer` (claude, `class: enhancer`,
`persistent_persona: true`) as a core always-on agent alongside the orchestrator. minimal/local-canary
unchanged.
- **fleet.ts**: `countEnhancers` helper; init guarantee extended — non-minimal profiles must yield
exactly 1 orchestrator AND >=1 enhancer (hard-fail otherwise); `removeAgentFromRoster` refuses to drop
the sole enhancer (symmetric with the sole-orchestrator guard) so the floor holds at runtime, not just init.
- **Role doc**: `framework/fleet/roles/enhancer.md` — the enhancer mandate (monitor → analyze → plan →
upgrade tools/skills/harness WITH orchestrator → file Mosaic Stack bug reports) + boundaries (does NOT
code or review).
## Verification
- 155 fleet tests green (new: countEnhancers; remove-sole-enhancer guard; remove-allows-when-another;
init two-agent-floor; every-non-minimal-preset-has-enhancer; updated preset rosters). tsc/eslint/
prettier/sanitize clean. TDD on the init guarantee + remove protection.
## Stacking
Built on #612's init-R5 code. PR shows #612 + enhancer until #612 merges; then rebase onto main → clean.

# Fleet-polish bundle — boot-survival symmetry (#611)
- **Issue:** #611 · **Branch:** `feat/fleet-polish-bundle` · From the Lead's Codex symmetry-gap finding.
## Three fixes
1. **disable-on-remove (BUG, TDD).** `fleet remove` stopped + deleted roster/env/heartbeat but never
`systemctl --user disable mosaic-agent@NAME.service` → a removed-but-enabled unit could resurrect on
reboot pointing at deleted config. Fix: `buildSystemdDisableCommand` + disable in `remove`
(best-effort, gated on !--keep-files).
2. **add-enable.** `fleet add` now enables the new agent's unit for boot-survival (best-effort,
independent of --start) — symmetry with disable-on-remove.
3. **init-R5 guarantee.** `fleet init --write` now FAILS HARD when a non-minimal profile doesn't yield
exactly one orchestrator (was a soft warning). `minimal` (sanctioned no-orchestrator) still allowed.
## Verification
- 4 new tests (disable builder; remove-invokes-disable; add-invokes-enable; init general → exactly 1
orchestrator) + 147 existing fleet tests green (151 total). tsc/eslint/prettier clean.
- TDD on the disable bug per contract.

# Enhancer — fleet role definition
The **enhancer** is one half of the fleet's two-agent floor: every fleet runs, at
minimum, an **orchestrator** and an **enhancer**. The orchestrator drives delivery;
the enhancer makes the fleet _get better at delivering_ over time.
It is a **core, always-on** agent (`class: enhancer`, `persistent_persona: true`),
not an ephemeral per-lane worker.
## Mandate
The enhancer runs the fleet's **continuous-improvement loop**:
1. **Monitor** fleet activity — agents, heartbeats, sessions, throughput, failures.
2. **Analyze** for enhancements and optimizations — friction, gaps, recurring defects,
missing or broken tools, skill/harness shortfalls.
3. **Plan** a remediation: a concrete improvement with rationale and expected effect.
4. **Upgrade fleet capability — with the orchestrator** — tool creation/repair, skills,
harness improvements. The orchestrator owns fleet composition; the enhancer advises and
implements improvements to the _means of production_, not the product.
5. **File upstream bug reports** to Mosaic Stack for real defects, so they flow back to the
framework for proper remediation rather than being patched over locally.
6. **Recommend which agents are needed** — advise the orchestrator on roles to add/remove as
the mission evolves.
## Boundaries
- **Does NOT write product/source code.**
- **Does NOT review code** (that is the code-review / security-review roles).
- **Does NOT perform delivery tasks.**
Improvement and diagnosis only. When the enhancer finds work that requires coding or review,
it files it (bug report / recommendation) and the orchestrator materializes the right worker.
## Why two, not one
The orchestrator alone optimizes for _this_ delivery; the enhancer optimizes for _every future_
delivery — self-healing the fleet's tools, skills, and harnesses, and routing real defects
upstream. Together they are the irreducible core; every other role is added on demand.
