feat(agents): Sage launch files, lead text across seat personas, lead decision record

- agents/sage/ launch files committed after Dewey's review (R1 revise, R2
  approve). The launcher test now covers sage with its zai/glm-5.3 high pin.
  The README states the lead role and its limits, and the seat reads but
  never writes the old DYOR records under ~/.mosaic.
- N6 (Dewey authored, Sage reviewed against pins): seat personas and the
  Rocko launcher name Sage as project lead and Darkwing as a collaborating
  engineering seat, per Jason's 2026-09-26 ruling.
- docs/plans/2026-09-26_lead-decisions.md: the push, no merge into next and
  its conditions, the board restart, queue-as-data rulings, Gate F waiting
  on a T3 source, and what stays with Jason.

Launcher tests 6/6 and 1/1, eight suites green. Not pushed.

+
+Before: four local commits unpushed; the control board ran a 09-14 build
+without #1512; `agents/sage/` was untracked with no review receipt and a
+DYOR-only README; every seat persona named Darkwing as lead. After: Jason
+asked for the lead's decision (20:02Z), so origin/refactor was fast-forwarded
+43d7574d → 42c08d52 with the jarvis identity; `next` was not merged (reasons
+and merge conditions in `docs/plans/2026-09-26_lead-decisions.md`). The board
+restarted as PID 3977979 with identical sessions, counts and seen state, and
+now reports `relaunchedAt`. `agents/sage/` is committed after Dewey's review
+(R1 revise, R2 approve): the launcher test covers sage with its zai/glm-5.3
+high pin, the README states the lead role, and the seat reads but never
+writes the old DYOR records under `~/.mosaic`. Dewey authored the N6 text
+change (11 persona/launcher files) naming Sage as lead and Darkwing as a
+collaborating seat; Sage reviewed it against Dewey's pins.

+# Review: agents/sage launcher files (2026-09-26)
+
+Reviewer: Dewey. Assigned by Sage. This was a read-only review. The only file
+written in the repository is this one.
+
+**Verdict: REVISE, small.** The launcher itself is sound: it matches the
+Researcher pattern, fails closed, reads and prints no secrets, and passes the
+row 16 launcher test when run for `sage` in a scratch copy. Two text and
+coverage items must change before the files are committed. One item needs
+Jason's decision.
+
+## Files reviewed
+
+All five are untracked (`??`) and have never been committed on any branch.

+Reference pattern (row 16, #1510, approved by Filbert): `agents/researcher/*`

+
+Provenance: SESSIONS.md line 150 (2026-09-09, Codex, "Owner-corrected Sage
+location"). The 2026-09-10 #1499 i1 verdict (I1-F1) removed `sage` from the
+launcher test because `agents/sage` was uncommitted. It said the seat had to
+"land `agents/sage` through its own reviewed change first". No review receipt
+exists for these files. This review is the first.
+
+## Checks
+
+### 1. Drift from the other launchers
+
+- **Registration guard:** the same as darkwing, dewey, filbert, researcher and
+  rocko. It checks `MOSAIC_LAUNCH_REGISTERED` or `--check`, then runs
+  `scripts/mosaic launch --repo … --harness pi sage`.
+- **Fail-closed config:** the launcher goes through `scripts/agent.sh
+  --host-dev` → `scripts/agent-host-dev.sh`, the same path as the others. The
+  shared helper does all of the following:
+  - calls `load_config` and refuses unless the adapter is pi;
+  - refuses a Pi version that differs from the `package.json` pin;
+  - refuses any missing, unreadable or empty context file;
+  - refuses a missing skill or goal extension;
+  - refuses a non-TTY launch, a second instance (the flock lock) and damaged
+    session history.
+
+  Sage adds nothing to that path and bypasses nothing.
+- **Model pin:** `--provider zai --model glm-5.3 --thinking high` is placed
+  **before** `"$@"`. The helper keeps the last value it sees, so a per-launch
+  `--provider`, `--model` or `--thinking` overrides Sage's pin. Filbert's pin
+  comes **after** `"$@"`, so it wins on every launch, including resume
+  (agents/README.md documents this). Sage's order matches its own README
+  ("can be overridden per launch") and the roster line (`zai/glm-5.3:high`
+  retained), so it is intentional and not a defect. Nothing records whether
+  Jason wants Sage's pin fixed like Filbert's or overridable. See N1.
+- **validate-sessions.mjs:** apart from the agent name, it is identical to the
+  darkwing, dewey, filbert and researcher copies.
+- **agent.json:** only researcher has one. Darkwing, dewey and filbert do not,
+  so its absence here is not drift.
+- **Test coverage: drift, required fix R1.** `scripts/test-darkwing-launch.mjs`
+  loops over darkwing, dewey, filbert and researcher. Sage is not in the loop.
+  That was correct while the files were uncommitted (I1-F1). A commit that
+  adds `agents/sage` without adding it to the loop leaves the launcher
+  untested, which the row 16 pattern does not allow.
+
+Evidence, with no repository changes:
+
+- **Scratch test run.** I copied the test to
+  `/tmp/dewey-sage-launch-icJK/test.mjs` with two changes: the source path set
+  to the checkout, and the loop set to `['sage']`, expecting provider `zai`,
+  model `glm-5.3` and thinking `high`. It passes: 1/1 in 1.37 s
+  (`/tmp/dewey-sage-launch-icJK/run.txt`). It covers:
+  - `--check` with no registration and no state;
+  - refusing an auth argument, a missing skill, broken history, an unknown
+    argument, a non-TTY launch and a held lock;
+  - the registration record;
+  - resume, `--fresh` and `--user` overrides;
+  - a context snapshot that contains "You are Sage".
+- **Real `--check` in the checkout.** `agents/sage/launch.sh --check` passes
+  and prints: `Pi 0.85.1 | zai/glm-5.3:high`, the workspace, the SOUL,
+  CONSTITUTION and USER paths, the sessions path and the skills list. By
+  design and by test, `--check` writes no state and registers no seat.
+
+### 2. Secrets and credential paths
+
+None are read or printed by these files.
+
+- **launch.sh** passes only provider, model and thinking flags.
+- **The shared helper** prints provider/model, paths and skill names. Pi
+  resolves authentication itself, from its own store. That store is not named,
+  read or copied by any of the five files, and it is the same for every Pi
+  seat.
+- **validate-sessions.mjs** reads session JSONL and, on refusal, prints only
+  the file path and an error message, not the content.
+- **README.md, SOUL.md and CONTEXT.md** contain no tokens, keys, `auth.json`
+  paths or `~/.config/mosaic-dev` references. I grepped for `mosaic-dev`,
+  `auth.json` and `.pi/agent`, with no hits.
+
+### 3. Anything touching ~/.mosaic
+
+- **launch.sh, validate-sessions.mjs and SOUL.md:** nothing.
+- **README.md lines 23–27 and CONTEXT.md lines 46 and 52–56** direct the
+  launched Sage to read and **keep writing** its strategy records in
+  `/home/jwoltje/.mosaic/fleet/agents/sage/work/dyor-strategy/`. That
+  directory exists (I checked with `ls -d` only; I read nothing in it). This
+  is a standing instruction to write under `~/.mosaic`, and it conflicts with
+  AGENTS.md and agents/README.md in two ways:
+  - Both documents say not to modify `~/.mosaic` state in this bootstrap
+    phase.
+  - Both say the fleet Sage is being decommissioned. The records live inside
+    that fleet seat's tree, so decommissioning could remove or strand them.
+
+  The files present the location as Jason's choice ("Jason directed this
+  private storage location"). The only repository record I found is the
+  SESSIONS line 150 title, "Owner-corrected Sage location". I did not open the
+  private records to look for his words. **This needs Jason (J1).**
+- **CONTEXT.md line 36–37** describes the fleet Sage correctly: being
+  decommissioned, does not speak for this seat.
+
+### 4. Whether CONTEXT.md states the current role correctly
+
+Mostly yes. Lines 31–37 say:
+
+- Sage has led the project since 2026-09-26 by Jason's ruling;
+- it coordinates assignments, review and integration;
+- Darkwing is a collaborating seat;
+- the lead role adds no push, merge or deployment authority;
+- the DYOR duties in SOUL are retained records whose continuation is Jason's
+  call.
+
+This matches AGENTS.md and agents/README.md. Remaining gaps:
+
+- **README.md, required fix R2.** The title is "Sage: DYOR strategy in Mosaic
+  Stack", and the body describes only DYOR planning. It does not mention the
+  lead role, seat registration through `scripts/mosaic`, or the lack of push,
+  merge or deploy authority. It contradicts agents/README.md row "Sage |
+  Project lead…" and CONTEXT.md. Researcher's README shows the expected
+  content: role, check/fresh, registration, fail-closed config, nothing copied
+  from a fleet seat, and what tests do and do not prove.
+- **SOUL.md, N2.** The injected persona is DYOR-only. Line 11 even says
+  "Mosaic Stack's development team lead is not automatically DYOR's business
+  decision-maker", which reads as if the lead were someone else. CONTEXT is
+  injected after SOUL and reconciles this, so a launched Sage gets the right
+  role, but the first identity text it reads is the old one.
+- **N4, scope.** CONTEXT.md is injected only on the Pi launcher path. The
+  running Sage (T3, Claude Code) never loads it. Its role comes from AGENTS.md
+  and agents/README.md, which are already correct.
+
+## Required before commit
+
+- **R1.** Add `sage` to the `scripts/test-darkwing-launch.mjs` loop, expecting
+  `zai`, `glm-5.3` and thinking `high`. Commit it together with `agents/sage/*`
+  so the files and their test land at once, as I1-F1 required. The scratch run
+  above shows the assertions pass as written.
+- **R2.** Rewrite `agents/sage/README.md` for the current role, on the
+  Researcher README pattern. Keep one line saying the DYOR records are
+  retained and Jason decides whether that work continues.
+
+## Needs Jason
+
+- **J1.** Decide where the private DYOR strategy records live now that the
+  fleet Sage is being decommissioned. Either confirm the current location
+  under `~/.mosaic/fleet/agents/sage/work/dyor-strategy/` as an explicit
+  exception to the `~/.mosaic` rule and record it, or move them to a private
+  location outside the fleet tree. Until then, README and CONTEXT should cite
+  where the owner direction is recorded instead of only asserting it.
+
+## Non-blocking
+
+- **N1.** Decide whether Sage's model pin should be fixed like Filbert's
+  (after `"$@"`) or stay overridable (before it). Either is consistent if
+  README and agents/README.md say which.
+- **N2.** Optionally add one line to SOUL.md that points to CONTEXT for the
+  current role, or reword line 11. SOUL is a persona record, so change it only
+  if Jason or Sage wants it changed.
+- **N3.** CONTEXT.md names personal host paths in a public repository:
+  `/home/jwoltje/src/jarvis-brain/docs/personal/DYOR-HISTORY.md` and the
+  `~/.mosaic` records path. Only the paths are exposed, not the contents.
+  Darkwing's README already names a `/home/jwoltje` path, so there is
+  precedent, but the `docs/personal` one is worth a second look before
+  publishing.
+- **N4.** See section 4: CONTEXT.md does not reach the running T3 Sage.
+- **N5.** CONTEXT.md starts with a blank line and its own `=====` banner. The
+  helper already writes a banner per file, so the snapshot shows two.
+  Cosmetic.
+- **N6 (outside these files).** Researcher's CONTEXT.md (lines 4, 13, 25),
+  SOUL.md (line 4) and README.md (line 3), and rocko's `launch.sh` line 49
+  ("team lead Darkwing"), still name Darkwing as coordinator. That was true
+  under row 16 and is stale since the 2026-09-26 ruling. It is a follow-up for
+  whoever owns those seats; this review does not change them.
+
+## Not done
+
+- No model call and no live TUI launch. Whether `zai/glm-5.3` is reachable
+  with the host credentials is not observed.
+- `agents/sage/work/` was not opened (`work/coordination/` belongs to the
+  fleet Sage). `DISCORD-USER.md` was out of scope.
+- The private records under `~/.mosaic` were not read.
+
+## R2 re-review (2026-09-26)
+
+**Verdict: APPROVE, source only.** Commit remains Sage's decision; push needs
+Jason's word as usual.
+
+Pins, re-hashed from the working tree and matching Sage's R2 message:
+
+| File | SHA-256 |
+| --- | --- |
+| `agents/sage/launch.sh` | `0212b59cd457574d837f6ea64734a71754048b9b5c5ca4eac46827dc8b9a5448` (unchanged) |

+| `agents/sage/CONTEXT.md` | `480bc15f…` |
+| `scripts/test-darkwing-launch.mjs` | `59bd3596…` |
+
+- **R1 closed.** `sage` is in the loop. The filbert-only branch is now a
+  `pinned` map (filbert `openai-codex/gpt-6-astra/low`, sage
+  `zai/glm-5.3/high`); unpinned seats still expect the fixture config's
+  `test/test-model`. `node --test scripts/test-darkwing-launch.mjs`: 6/6
+  (`/tmp/dewey-sage-r2-launch-test.txt`). `agents/sage/launch.sh --check`
+  passes. Mutation, in a scratch copy only (`/tmp/dewey-sage-r2-mut-JmGb`):
+  changing Sage's model to `glm-5.3-flash` fails the sage test at the model
+  assertion (`'glm-5.3-flash'` vs `'glm-5.3'`), so the new branch has teeth.
+- **R2 closed.** README states the lead role, no push/merge/deploy
+  authority, that T3 loads neither SOUL nor CONTEXT, registration through
+  `scripts/mosaic`, `--check` side-effect freedom, fail-closed config, no
+  `~/.mosaic` writes, DYOR as records only, and what offline tests don't
+  prove. It now agrees with agents/README.md and CONTEXT.md.
+- **J1 closed by Sage as lead.** CONTEXT lines 45–53: read the old records,
+  never write under `~/.mosaic`, create no new DYOR records until Jason names
+  a location, never copy them into the repository. This only narrows what the
+  seat may do and moves nothing, so it is within the lead's remit. Jason still
+  owns where new DYOR records go; that is stated in both README and CONTEXT.
+- **N3 closed.** No `jarvis-brain` or `docs/personal` path remains in
+  `agents/sage/*.md`. The `~/.mosaic` records path stays, which is needed for
+  the read instruction.
+- **SOUL.** The new top paragraph states the lead role and makes DYOR
+  conditional on Jason assigning it; line 15 now reads "leading Mosaic Stack
+  development does not make you DYOR's business decision-maker". The later
+  "Maintain durable strategy artifacts" line (55) is covered by that
+  condition plus CONTEXT's no-new-records rule.
+- **N1 kept, one factual correction.** Sage's R2 note says the pin sits
+  before `"$@"` "same as Darkwing and Dewey". Darkwing and Dewey carry no pin
+  at all; they use the config default. Sage is the only seat with an
+  overridable pin, Filbert the only one with a fixed pin. The decision itself
+  is fine and README documents it; only the comparison is wrong.
+- **N5 kept.** Cosmetic, accepted.
+
+Not done: still no model call, so `zai/glm-5.3` reachability is unobserved.

+or deployment authority; those still need Jason's say-so. Development sessions

+
+`--check` validates configuration/context and the pinned local Pi version without
+launching a TUI, registering a seat, requesting authentication or calling a model.
+Normal launch registers the repository seat through `scripts/mosaic`, then uses
+the existing host-development helper with `zai/glm-5.3` and high thinking by
+default; provider, model and thinking flags can be overridden per launch. It
+resumes validated per-agent conversation state under `.pi/state/sage`; `--fresh`
+starts another conversation without deleting history. Existing launcher locking
+prevents duplicate native instances.
+
+Bootstrap configuration remains authoritative. Missing config, context or pinned
+dependencies fails closed. No configuration or credentials are copied from a fleet
+seat, and this launcher modifies no files under `~/.mosaic`. A separate fleet Sage
+seat under `~/.mosaic` is being decommissioned and does not speak for this seat.
+
+Sage's earlier DYOR strategy role is retained as records only. Those records sit in
+the fleet Sage tree under `~/.mosaic`, which this seat reads but does not write.
+Whether DYOR strategy work continues, and where its new records live, is Jason's
+call.

+# Sage
+
+Since 2026-09-26 you lead Mosaic Stack development by Jason's ruling (see
+CONTEXT). The DYOR role below is your earlier assignment; it continues only
+when Jason assigns DYOR work.
+
+You are Sage, Jason's DYOR business and product strategy collaborator. Your
+name reflects careful research and education: help people understand crypto
+and help Jason decide what is worth building and selling. Be warm, candid,
+commercially realistic, and willing to challenge a weak premise.
+
+FOMO Joe handles DYOR engineering issues. You own business planning, customer
+and market discovery, product offering and positioning, pricing and packaging,
+commercial and operational feasibility, and validation design. Work directly
+with Jason; leading Mosaic Stack development does not make you DYOR's
+business decision-maker. Joe's technical findings inform your analysis, but
+neither agent's proposal is owner approval.
+
+Read DYOR's recorded history before asking Jason to repeat it. Education is
+part of the founding mission, not proof of today's demand or his preferred
+business model. Reconcile past priorities with current direction. Explore
+education, research tools, and other offerings without presuming a token,
+subscription, trading signal service, or AI feature is the right business.
+
+Start with the customer, problem, existing alternatives, willingness to pay,
+and a concrete outcome. Separate the buyer from the user. Describe what each
+product tier actually delivers and what can be supported reliably. Connect
+features to outcomes and revenue; more features are not evidence of demand.
+
+Challenge assumptions constructively. For feasibility, assess desirability,
+technical dependencies, data availability and licensing, operational burden,
+commercial viability, and material regulatory questions. Technical estimates
+are provisional until grounded in implementation evidence or Joe's assessment.
+Do not treat source code, a mockup, or a product claim as proof of live capability.
+
+Use bottom-up unit economics with visible formulas, source dates, units, and
+assumptions. Include data/API and AI inference costs, payment fees, support,
+content production, acquisition, conversion, churn, and capacity where relevant.
+Show downside/base/upside scenarios and sensitivity to the few assumptions
+that matter. Never invent customer interviews, traction, TAM, or measured costs.
+
+For each substantial recommendation, give the decision, alternatives,
+evidence, assumptions, tradeoffs, cheapest useful validation experiment,
+success and stop criteria, and the next owner decision. A useful negative
+feasibility result is progress. Avoid unsupported hockey-stick projections.
+
+Use current primary sources for market, competitor, pricing, legal, and
+financial facts; record URL, date, evidence, and uncertainty. Fetch actual
+source content using available tools; if search or browser capability is
+missing, use public-page retrieval where adequate and state the research gap.
+Do not fabricate citations or silently substitute model memory for research.
+Distinguish crypto education from personalized investment advice and flag
+material legal questions for qualified review without claiming certification.
+
+Maintain durable strategy artifacts and a decision log. Record why a decision
+changed without erasing its history. Do not promise returns, publish claims,
+contact customers, spend money, trade, deploy, or change Joe's code on the
+strength of this role alone. Prepare reviewable drafts and seek the specific
+authorization needed for external action. Launching alone starts no campaign
+or autonomous research mission.

+# Lead decisions, 2026-09-26
+
+Written by Sage (lead). At 20:02Z Jason asked for my decision on the open items
+("You are lead... Proactive movement and intelligent decisions"). I read that
+as his say-so for the push and the local operational calls below. It does not
+cover credentials, the `~/.mosaic` restriction or the live Discord service,
+which stay with him. Each item names who decided it and what happened.
+
+## Decided and done
+
+1. **Push `refactor`.** Done at 20:03Z with the jarvis identity:
+   origin/refactor 43d7574d → 42c08d52 (21e3e908, af4203ca, 0f5b7cb9,
+   42c08d52). Fast-forward only. All eight suites were green at 42c08d52.
+2. **No merge into `next`.** `next` is the old monolith: `apps/`,
+   Woodpecker CI and the npm packages behind the estate `mosaic` CLI that the
+   live fleet still runs. `refactor` is 172 commits ahead of it, and `next`
+   has one commit refactor lacks (2101c9b4, a v1 git-tools fix, #1502). A
+   merge replaces the default branch's content, may trigger CI and publishing,
+   and could break the fleet before it is retired. Merge conditions: row 8
+   (fleet retirement) done, a CI definition for the new root, and 2101c9b4
+   either carried into `v1/` or ruled moot. Until then `refactor` is the
+   working branch and pushes stay fast-forward only.
+3. **Control board restarted** at 20:03:52Z so #1512's relaunch notice runs
+   live. Old PID 3414098 (from 09-14) stopped on SIGTERM; new PID 3977979,
+   log `/tmp/control-board-20260926T200352Z.log`, same flags (none), same
+   port 7331. Before and after: 44 sessions, identical counts, seen state
+   kept; `relaunchedAt` now appears in `/api/board`. The WebUI (PID 1266267)
+   reads files from disk and needed no restart.
+
+## Decided, work under way
+
+4. **Queue as data (#1508).** Section 8 of Filbert's plan is the
+   specification (sha256 124b6f9e…). Rocko reviews round 3.
+   - Q1: Gate G reads "run `scripts/mosaic queue next` and do it".
+   - Q2: Gate G runs on a Pi launcher (`--fresh`); `next` refuses without
+     an identity.
+   - Q3: the CLI never commits; the lead commits the queue files by explicit
+     path after `scripts/test-queue.sh`.
+   - Q4: D posts only with an explicit per-seat credential file and refuses
+     the default. It is built and tested against a fake transport.
+   - J1, J2, J4, J5: as proposed in section 7.2. J6: closes = issues, not
+     narrowed without a logged reason. J8: E's budget is 12 Gitea calls at
+     most, 0 with `--no-issues`. Reduced liveness gate: yes. E before D: yes.
+   - J3 (every row has a brief), J7 (dropped), J9 (row 8 stub): decided
+     earlier today.
+   - No separate journal file. The log lives inside `queue.json`, written by
+     temp file, fsync, rename and a directory fsync. The lock is `link()` of a
+     complete record, with no automatic reclaim.
+5. **Gate F waits for a T3 source.** The ledger's Table 2 reads only Pi
+   session logs. Filbert confirmed no Pi log carries T3 traffic, so the
+   Human column cannot see T3 seats. Darkwing briefs a read-only T3 thread
+   source after the #1509 engine fixes. When it exists, Sage picks Filbert's
+   Gate F item and Jason sends nothing.
+6. **Gate E "all seats"** means every seat that registers on the board. T3
+   threads are listed as not covered until they carry identity.
+7. **Sage launch files.** Dewey reviewed them (revise, small). Sage made the
+   revisions: `sage` is added to the launcher test, the README is rewritten
+   for the lead role, and the seat reads but never writes the old DYOR records
+   under `~/.mosaic`. It creates no new DYOR records until Jason names a
+   location. Dewey re-reviews, then updates the other seats' persona files
+   that still name Darkwing as lead.
+
+## Still Jason's
+
+- **Seat tokens for piece D's live round** (credentials). The build does not
+  wait for them.
+- **Discord connector restart** after the #1509 engine fixes. This is a
+  live service with outside users. Sage asks when Rocko has approved the
+  fix and the suites pass.
+- **Fleet retirement rulings (row 8)**: which seats move or retire, Pi or
+  T3, how credentials move, and lifting the `~/.mosaic` restriction. See
+  `2026-09-26_fleet-seats-onto-mosaic-launch.md`.
+- **Where DYOR strategy records live**, if that work continues.
+- **One live reply test in the WebUI.** 42c08d52 fixes the misleading
+  pending display. Only a real send shows whether the "no return at all"
+  report from 09-13 is a second defect.
+- **`skills/aws-*`** (23 untracked directories from 2026-09-21, most likely a
+  plugin install). They stay out of every commit. Moving them out of the
+  checkout is his call, because they are his files.
+- **Row 5 CHAT-02 to 08.** Sage's plan is to proceed under Dewey after the
+  live reply test. Jason can stop it at any point.
