Merge pull request 'Move the correx server off :8080 to :8090 (mavgpud port conflict)' (#3) from task/695-move-the-correx-server-off-8080-to-8090 into master

mavgpud.service, the Maven GPU supervisor, is an enabled systemd user unit that
binds *:8080 and restarts on kill. The correx server wanted the same port, so
qa-stack died with BindException and the QA stack never came up. Worse,
qa-stack's --stop ran `fuser -k 8080/tcp`, which killed mavgpud rather than a
correx server; systemd then restarted it straight into the port it had just
freed, so it won the race every time.

Moves the default to 8090 in the four places that have to agree: ServerConfig,
ConfigLoader's fallback, the CLI's DEFAULT_PORT, and the TUI's -port flag. A
mismatch between any two of them is a client that cannot find its own server.

The machine-local halves are not in this diff and were applied on disk:
`~/.config/correx/config.toml` pinned `port = 8080` explicitly, which overrides
the code default, and `scripts/` is gitignored so qa-stack.sh's five references
(including the --stop kill, now aimed at 8090) live only on this box.

Verified live: the server binds 8090 and answers /health while mavgpud keeps
8080. Left open in #695: mavgpud also spawns a llama-server on :10000, which is
qa-stack's router port, and qa-stack pkills that pattern.

+ * Genuinely one-shot per retry occurrence (#306): the hint is keyed to the LATEST

+name: ethos-design
+description: Use when building or editing any user interface for an Ethos app (muzick, kdrive, nginx panel, xray manager, kaneo, or any new kvmx.ru app), when authoring or extending components in the @ethos/ui package, or when any frontend/React/HTML/SVG work must carry the Ethos visual identity. Triggers on requests to design a screen, build a component, add an app to the system, restyle existing UI, create icons, or set up per-app theming. Covers the token system, the five laws, the mono/sans split, warm-room depth, per-app accent + motif, the shared shell (desktop + mobile), copy voice, the trap list to refuse, and the render-based verification protocol.
+---
+
+# Ethos
+
+Ethos is the shared design language for the kvmx.ru self-hosted apps. One system, one character, many apps. Switching from kdrive to the xray manager should feel like switching tabs in one instrument, not opening a different product.
+
+## The thesis: instruments, not appliances, that don't lie
+
+These apps are tools the operator runs their own infrastructure with — closer to an oscilloscope, a mixing desk, or good anodized audio gear than to a consumer product. Dense where it needs to be, every element earning its place, honest about the machinery instead of papering over it.
+
+But not cold. The move nobody else makes: **warmth AND honesty in one room.** Consumer apps give warmth with no honesty (glossy, hides state behind a spinner). Dev dashboards give honesty with no warmth (cold, dense). Ethos is a calm, warm, well-lit space that still shows real throughput, real queue depth, real bytes. It can do both because the operator is the only user — the apps don't need to sell or hide anything.
+
+Design failure looks like either extreme: a techy grey dashboard, or a glossy blurred-glass consumer screen. Both are the trap.
+
+## The five laws (non-negotiable, shared across every app)
+
+1. **Mono/sans split is law.** Geist Mono for anything the machine owns — ips, ports, hashes, sizes, timestamps, ids, paths, throughput, durations, bitrates, counts, percentages. Geist Sans for anything a human wrote — labels, prose, headings, track/file names. This single rule is the strongest signature; it must read identically across every app. A label is human (sans); its value is machine (mono). `Bitrate` in sans, `1411 kbps` in mono.
+
+2. **Depth from light, not blur.** Elevation comes from soft warm shadows, layered surface steps in the neutral ramp, and 1px hairline borders. Never `backdrop-filter`/frosted glass, never glossy gradients. Reads engineered, not soft, and costs nothing per repaint.
+
+3. **Shared shell.** Identical app frame everywhere — same rail/topbar geometry, same status grammar, same ⌘K command surface. See the shell anatomy below. Per-app difference is only accent + motif, never structure.
+
+4. **Mechanical motion.** 120–180ms, `cubic-bezier(0.2, 0, 0, 1)`, no bounce, no spring. Motion confirms a state change and gets out of the way. Respect `prefers-reduced-motion`.
+
+5. **Show the machinery.** Real numbers over spinners. Queue depth, bytes/sec, buffer %, actual progress, indexed counts. A vague "loading…" is the appliance move — never do it. Empty and error states state what's true and what to do, in the interface's voice.
+
+### The balance principle (how the accent behaves)
+
+**Content is the color. Accent is the signal. Shell is quiet.** The apps hold warm content — album art, files, manga panels — and that content carries the color. The shell stays quiet and warm so the content glows. The accent is NOT fill-everything paint; it marks the one thing that matters: active nav, focus rings, primary action, the played portion of a scrubber. If a whole panel is washed in the accent, it's wrong — pull it back.
+
+## Tokens
+
+Single source of truth is `ethos.tokens.css` — the neutral system, the light-theme block, and the per-app override slots, shipped as CSS custom properties. (Generate typed TS from it later if an app wants typed access; the CSS stays authoritative so nothing drifts.) Values below are the dark-theme defaults.
+
+### Neutral ramp — warm, brown-tinted (NOT cool grey, NOT cream)
+```
+--bg-0: #14110D   /* deepest room */
+--bg-1: #1B1712   /* surface */
+--bg-2: #221D17   /* raised */
+--bg-3: #2C261D   /* hover / raised */
+--bg-4: #372F24   /* pressed / high */
+--line:    rgba(244,234,220,0.09)   /* hairline */
+--line-hi: rgba(244,234,220,0.16)   /* hairline emphasized */
+--text-hi:      #F4EEE4   /* human primary */
+--text-mid:     #B4AA98   /* human secondary */
+--text-lo:      #756C5C   /* human tertiary / idle */
+--text-machine: #9C917D   /* mono default */
+```
+
+### Type
+```
+--sans: 'Geist', -apple-system, system-ui, sans-serif
+--mono: 'Geist Mono', ui-monospace, 'SF Mono', Menlo, monospace
+```
+Scale: display 32–44 / heading 20 / body 14–16 / label 10–11 uppercase 0.08–0.12em tracking / machine data 12–15 mono. Mono always `font-feature-settings: "tnum" 1, "zero" 1` and slight negative tracking. Headings go editorial and large; let type be a memorable part of the design, not a neutral delivery vehicle.
+
+### Motion / radii / shadow
+```
+--ease: cubic-bezier(0.2, 0, 0, 1)
+--fast: 130ms   --med: 170ms
+--r-sm: 8px  --r-md: 12px  --r-lg: 18px  --r-xl: 24px
+--shadow-soft: 0 2px 8px rgba(0,0,0,.35), 0 12px 32px rgba(0,0,0,.28)
+```
+Fonts are self-hosted (subset + woff2, immutable caching, served off own nginx). No Google/Vercel font CDN — it phones home and fails the threat model.
+
+## Per-app fingerprint (ask, don't assume)
+
+Each app gets exactly two things of its own — one accent hue and one motif — set in a single `[data-app]` block in `ethos.tokens.css`. Everything else is inherited.
+
+**Do not pick these silently.** When a new app joins the system, run a short intake with the operator before writing any override:
+
+- Ask for the **accent**: a name and a hex. Bring **2–3 of your own suggestions** grounded in what the app *does* — reason from its function and content, not from a palette wheel — and say why each fits. The operator decides; your suggestions are there to react to.
+- Ask for the **motif**: the recurring geometric signature tied to the app's function. Again, offer a couple of options with a one-line rationale each. A motif shows up in the app mark, empty states, loading, the favicon, and one hero moment.
+- Once chosen, fill the `[data-app]` TEMPLATE in `ethos.tokens.css` (accent + the derived `-hi/-dim/-line/-glow`) and seed the motif (a symbol in the icon set, plus any gradient hooks).
+
+The one worked example that already exists is **muzick — honey amber `#EDA24E` · waveform**; use it as the reference for how an override block and a motif are shaped, not as a set to copy from. Same skeleton, different soul.
+
+## Shared shell anatomy
+
+**Desktop (≥ 640px):** vertical `Rail` (64px, icon nav, active = accent icon + `accent-dim` bg + 3px accent edge) · `TopBar` (56px, wordmark + ⌘K search + right-aligned machine readouts) · scrollable `Main` · optional docked bar (e.g. muzick's player). Command palette (⌘K) is the shared command surface.
+
+**Mobile (≤ 640px) — shell reflow, same law for every app:**
+- Rail → full-width bottom tab bar (thumb reach). Active = accent icon + short top edge mark. Keep to **≤ 5 primary tabs**; fold secondary nav into a parent and push settings into the header. More than 5 is past the thumb ceiling.
+- TopBar sheds what it can't afford — the wide machine readouts drop from the header and relocate to where there's room (detail views, per-row values). Honesty is relocated, never deleted.
+- Large docked bars collapse to a compact mini (thumb + title + primary action), with any waveform/scrubber condensed to a thin accent progress line. The motif is expressed at whatever scale the form allows.
+- Heroes restack to single column: content-art centered and fluid (`aspect-ratio: 1`), heading down a step, spec rows wrap.
+
+## Icons
+
+The set is `ethos-icons.svg` — a `<symbol>` sprite. Reference a glyph with `<use href="/ethos-icons.svg#i-NAME"/>`; color and size come from the consumer. One 24px grid, one stroke width (~1.7), one corner radius, `stroke-linecap/linejoin: round`, `fill: none` line style (filled only for transport glyphs — play, pause, prev, next, more). **Extend by adding a `<symbol>`** on the same grid and hand; never diverge, and never import lucide or a generic pack — that breaks the single-hand rule. Two motif seeds ship in the set (`i-wave`, `i-grid`) to start apps from.
+
+## Copy voice
+
+Words are design material. Name things by what the person controls, not how the system is built — but Ethos still shows machine values, so: the **label** is human (sans, plain), the **value** is honest (mono). Active voice, sentence case, one name per action through the whole flow (a button that says Publish yields a toast that says Published). Errors don't apologize and are never vague — they say what happened and how to fix it. Empty states are invitations to act. Register is terse and plain, no filler.
+
+## Traps to refuse
+
+These are the defaults that make a design generic. Do not ship them, even if asked casually:
+
+- **Frosted glass / `backdrop-filter` over a blurred hero photo** — the 2023 AI-premium tell, and a repaint cost. Depth comes from light instead (law 2).
+- **Cream (#F4F1EA) + high-contrast serif + terracotta accent** — the AI-cream default; terracotta near #D97757 also reads as an Anthropic tell.
+- **Near-black + one acid-green/vermilion accent** — the other AI default.
+- **Accent as wash** — accent filling a whole panel. It's a signal, not paint (balance principle).
+- **Spinners / vague "loading…"** — hiding real state. Show the number (law 5).
+- **Shadows/glass for elevation instead of hairlines + surface steps.**
+- **Absolute-positioned `inset: 0` fill divs for backgrounds.** They stay contained only by a positioned overflow-hidden parent, and escape to the whole viewport in stricter renderers. Put the gradient/background directly on the sized element (the 260px art box, the 52px thumb), not on an inner fill layer. This is a real bug that has shipped.
+- **Google/Vercel font CDN** — self-host (law-adjacent, threat model).
+- **`localStorage`/`sessionStorage` in sandboxed artifact demos** — fails silently; use in-memory state for demos, sqlite for real apps.
+
+## Build process
+
+Plan → critique → build → **screenshot** → critique → fix. Match complexity to the vision; spend boldness in one place (the motif) and keep everything around it quiet. Before calling something done, remove one accessory.
+
+## Verification protocol (do not skip)
+
+**"Can't see it" means unverified. Never sign off on computed values as a substitute for a render.** Reading back a color or a token value confirms the value parsed; it does NOT confirm the layout, containment, stacking, or overflow. A screen can be completely broken while every computed color is correct.
+
+Before declaring any screen done:
+1. Render it and **actually look at the pixels.** Screenshot, view, critique.
+2. **Geometry check:** no horizontal overflow (`scrollWidth === clientWidth`); key elements sized and contained (an art box is its own dimensions, not the viewport); nothing painting the full screen that shouldn't.
+3. Check **both** desktop and mobile (cross the 640px line) before "done."
+4. If you genuinely cannot screenshot, **say so plainly and hand visual sign-off to the human.** Do not fill the gap with confidence. State what you verified (geometry) and what you couldn't (appearance).

+# Audit — ContextEntry role/layer placement (Vikunja #312)
+
+**Date:** 2026-07-26 · **Scope:** every `ContextEntry` producer on the orchestrator stage path.
+**Output:** table + recommendations. No code changes.
+
+## How placement actually resolves
+
+`PromptRenderer.render` (core/inference/.../PromptRenderer.kt):
+
+1. **Any** entry with `layer == L0` **or** `role == SYSTEM` → folded into the single leading
+   system message, ordered by `(layer.ordinal, entry.ordinal)`. Role is irrelevant at L0.
+2. Everything else renders inline as its own message, ordered by `entry.ordinal`
+   (layer priority is a tiebreak only when all ordinals are 0 — router chat).
+3. `sourceType == "steeringNote"` **and** SYSTEM-folded → additionally re-emitted as a trailing
+   user "Reminder" turn.
+4. `sourceType ∈ repairMandateSourceTypes` (currently `{"retryFeedback"}`) → pulled out of the
+   inline flow and emitted as the **final** message, role user.
+
+So there are three destinations, not four: **leading system fold**, **inline transcript**,
+**trailing user slot**. `EntryRole.SYSTEM` is not "high salience" — it is "buried at the top".
+
+## Inventory
+
+| Entry (sourceType) | Producer | Current layer/role → renders as | Recommended | Rationale |
+|---|---|---|---|---|
+| `retryFeedback` | ContextFeedback.kt:34 | L1/USER → **trailing** | keep | Reference implementation (#293). |
+| `recoveryTicket` | ContextFeedback.kt:118 | L1/SYSTEM → **system fold** | **→ USER + trailing** | ⚠️ Highest-value defect. The recovery stage exists *only* because of this ticket, and its mandate ends up above the whole transcript. Same shape as `retryFeedback`; got the opposite treatment. |
+| `remainingDelta` | ContextFeedback.kt:186 | L1/SYSTEM → **system fold** | **→ USER + trailing** | ⚠️ Loop-state, recomputed every turn a write lands. It is the stage's completion signal and it is buried, *and* mutating it invalidates the cached system prefix each turn — the one cache anti-pattern #312 asked to flag. Trailing is both more salient and cache-safe. |
+| `groundingFeedback` | ContextFeedback.kt:89 | L1/SYSTEM → **system fold** | **→ USER + trailing** | Gate verdict on a returned plan; "emit a corrected plan" is a repair mandate by any reading. |
+| `rejectionFeedback` | SessionOrchestratorContext.kt:117 | L2/SYSTEM → **system fold** | **→ USER + trailing** | Literally operator voice ("the operator declined"). Escalation-grade; the user channel is where it belongs. |
+| `steeringNote` (locked) | Context.kt:80 | L0/SYSTEM → system fold **+ trailing anchor** | keep | Already double-anchored. |
+| `steeringNote` (unlocked) | Context.kt:94, ToolExec.kt:528 | L2/USER → **inline** | keep, note inconsistency | The renderer's anchor only catches the SYSTEM variant, so the two steering paths get different salience. Cosmetic, not load-bearing. |
+| `artifactRepair` | Artifacts.kt:132 | L2/USER → inline, but **sole entry** in its pack | keep | Isolated tools-less pack; already the last (only) message. |

+
+## Recommendations, in order
+
+1. **Re-role the four escalation entries** (`recoveryTicket`, `remainingDelta`,
+   `groundingFeedback`, `rejectionFeedback`) to `EntryRole.USER` and add their sourceTypes to
+   `PromptRenderer.repairMandateSourceTypes`. One-line change each plus the set.
+
+2. **Guard the scarcity invariant first.** `repairMandateSourceTypes` currently joins all matches
+   with `\n\n`. With one member that is fine; with five, a recovery stage on a retry with an unmet
+   delta emits three stacked "mandates" and the channel stops being authoritative. Before (1) lands,
+   the trailing slot needs either a priority order emitting the single highest-precedence entry, or
+   one consolidated block under a single header. Suggested precedence:
+   `recoveryTicket > retryFeedback > groundingFeedback > rejectionFeedback > remainingDelta`.
+   `remainingDelta` is the exception worth appending unconditionally — it is the completion signal,
+   not a competing mandate.
+
+3. **Cache note.** All four moves are *out of* the system prefix and are therefore cache-positive.
+   `remainingDelta` is the biggest win: per-turn mutation currently sits inside the cached prefix.
+   No move *into* system is recommended anywhere.
+
+4. **Do not touch tool-role failures.** Escalation belongs at the repeat detector (#309), not at
+   each failure site.
+
+Everything above stays event-derived (invariant #9); the trailing block is synthetic and should keep
+its `## `-headed, non-conversational framing so it never reads as a real operator turn.
+
+## Note on sequencing
+
+The sprint deferred #312 behind #307 (manifest event) "so the audit has ground truth". Not needed —
+placement is statically determined by `PromptRenderer` + the producer's role/layer, both read
+directly. #307 remains useful for verifying the *result* of recommendation (1) on a live run.

+# Sprint: "Close the loop" — 2 weeks
+
+**Dates:** 2026-07-23 → 2026-08-06
+**Source:** Vikunja Correx project (id 4), 30 open tasks reviewed
+**Theme:** Real per-stage validation, warm-discovery freestyle runs, robust orchestration under failure
+
+---
+
+## Goal 1 — Real per-stage validation: land the LSP gate + fix build-gate wiring
+
+**Why.** Multiple freestyle QA runs hit the same wall: the build-gate only fires at the terminal stage, so 8-10 hopeful writes stack before the truth-check, and when it fails there's no budget left (#167 epic calls this the "open-loop" disease). #80 is the filed fix and its deferral condition was observed on 2026-07-18 run 4a41417b — promote now.
+
+**Tasks.**
+- **#80** [EPIC] LSP validation gate — real per-stage gate + terminal typecheck replacement. Design finalized in the task body; break into the 5 sub-tasks listed there. Container for the work below.
+  - **#310** ✅ LSP diagnostics runner: anchor read on server readiness, not the 750ms timer (kills phantom unresolved-import).
+  - **#311** ✅ LSP gate: lint-class diagnostics (unused/deprecated) must not fail the run — classify by `DiagnosticTag`, not severity.
+- **#263** ✅ Auto build-gate never fires on real freestyle scaffold — promotion attaches to no reachable stage. Blocks the terminal safety net #80 doesn't replace.
+- **#267** Verify build-gate actually fires + re-scope #40 (LSP obsoletes the typecheck alias) — one live run settles both. Acceptance gate for the whole goal; do last.
+
+**Exit.** One live freestyle run where every write stage gets LSP diagnostics scoped to its write blast-radius, terminal build-gate fires, and a stranded-scaffold case goes to recovery instead of `WorkflowFailed`.
+
+**Sequencing.**
+- Mon: #80 sub-task 1 (cheap floor — populate the existing per-stage `static_analysis` seam with file-local one-shots in the freestyle compiler). Same-day ship; de-risks everything below.
+- Week 1: parallel track on #263 (build-gate wiring).
+- Week 2: #80 sub-tasks 2/3/4 — LSP4J wiring, pull-diagnostics, server pool, per-stage integration.
+- Week 2 tail: #310, #311 (readiness anchor + DiagnosticTag classification), then #267 as the acceptance live run.
+
+---
+
+## Goal 2 — Make freestyle runs start warm and converge: discovery prompts, impl decomposition, ACR
+
+**Why.** The kernel executes what it's told; near-term leverage is what it's told. #260/#261 sharpen upstream (discovery + per-feature stages), #305/#306 make run N+1 actually carry forward from the event log — the two halves of the ACR thesis still unimplemented. #297 kills a budget-burning failure mode mid-discovery.
+
+**Tasks.**
+- **#260** Freestyle SDLC: prompt-only upgrades — exhaustive discovery prompt + analyst DoD artifact (the contract the rest of the run is judged against).
+- **#261** Freestyle SDLC: decompose impl stages into features/sub-tasks (structural, deferred — but it's what makes per-stage LSP from Goal 1 actually bound blast-radius).
+- **#305** ACR: accrete task knowledge externally so discovery starts warm (model-agnostic) — warm-start half of #168's remaining follow-on.
+- **#306** Sticky ACR steer-away hint: fires every turn + coarse signature collapse — makes delivered concepts usable; without this ACR delivery is noise.
+- **#297** Analyst CoT indecision loop burns full reasoning budget, emits nothing — recovery hygiene in the stage the goal is sharpening.
+
+**Exit.** A second freestyle run on a fresh repo where DoD is recorded, impl stages are feature-bounded (so Goal 1's LSP scope is real), and the discovery stage carries accreted task knowledge from a prior run on an adjacent repo.
+
+**Sequencing.**
+- Day 1 (parallel): #260 — files-only, doesn't block on anything.
+- Week 1 mid: #297 (analyst CoT fix — same stage family #260 touches).
+- Week 2: #261 (impl decomposition — depends on #260's DoD existing to decompose against), #305/#306 (ACR — pairs with the warmed discovery stage).
+
+---
+
+## Goal 3 — Orchestration & recovery robustness: stop the unrecoverable kills and runaway recoveries
+
+**Why.** Two failure modes currently end runs that shouldn't end: a single provider going down mid-run (#299), and the recovery stage burning its budget against a stale failure-cap it can't clear (#304). Both waste full event logs. #307 is the cheap observability floor that makes the rest debuggable.
+
+**Tasks.**
+- **#299** Single provider death → unrecoverable session kill (`NoEligibleProvider` on retry) — re-route, don't die.
+- **#300** HealthMonitor detects provider loss ~18s too late (reactive, not gating) — gates #299's recovery path on a fast signal.
+- **#304** Recovery stage runs expensively then run dies on stale failure-cap — wasted work; the cap must reset on the recovery's own progress.
+- **#309** Recovery stage: apply same-fingerprint loop-breaker + repair-ledger — the runaway root cause; closes the loop Goal 3 started. Now lands on top of #312/#313: `recoveryTicket` is USER-role in the trailing slot at highest precedence, and the loop-breaker is the agreed place to escalate a repeated tool failure out of tool-role (per-failure sites stay tool-role).
+- **#307** Observability: no event records the assembled stage-context manifest — cheap event, makes every above failure diagnosable post-run.
+
+**Stretch (if #307 lands fast):** **#308** Background-process execution + monitor tool for long-running shell commands — unblocks real test gates but not load-bearing for the goals above.
+
+**Exit.** A live run where provider downtime is logged + recovered around, and a recovery stage that either converges or breaks the loop with a recorded repair ledger rather than dying on a stale cap.
+
+**Sequencing.**
+- Week 1: #307 (manifest event — cheap, unblocks debugging of everything below).
+- Week 2: #299 + #300 together (provider-death path), #304 + #309 together (recovery runaway path).

+
+### Goal 1 progress — 2026-07-26
+
+- **#310 ✅** (commit `a95475be`). `awaitDiagnostics` waits for one push per URI then a *quiescent*
+  period anchored to the last server publication (`awaitAll` + `awaitQuiet`), not a 750ms timer
+  started at `didOpen`. Kills the half-loaded-project phantom unresolved-import.
+- **#311 ✅** (commit `f61864ff`). `LspDiagnostic.tags` (lowercased `DiagnosticTag` names) is carried
+  from LSP4J through the event; `SessionOrchestratorGates2` gates on `severity == error && !isLint`.
+  A `noUnusedLocals` tsconfig promoting TS6133 to *error* no longer hard-fails a run that no rewrite
+  could clear. Lint diagnostics stay recorded and visible, just non-gating. Classification by
+  protocol tag, not a TS-code whitelist. Test: `core/events/.../LspDiagnosticTest.kt`.
+- **#263 ✅** (commit `867e99d1`). Two findings on trace:
+  - The *reported* selection bug was already fixed by `159b3f1e` (#277) — `autoGateStages` is every
+    write-declaring stage **plus** `terminalStageId(plan)`, so a non-writing review terminal is
+    gated and `runExecutionGate` promotes it to PROJECT off the real `FileWritten` manifest. The
+    2026-07-18 evidence was stale.
+  - The hole that remained: any stage declaring `build_expectation: project|tests` zeroed the whole
+    auto-gate set, so a plan building at stage 3 of 9 had nothing verifying the six stages written
+    after it. A declared build now suppresses only the redundant *per-writing-stage* gates; the
+    terminal floor always stays.
+  - Left deliberately: the gate chain still short-circuits before the execution gate when the
+    contract gate fails. The stage fails either way — cheap gates first, no COMPLETE-lie.
+
+**Goal 1 remaining: #267** — the acceptance live run. Fold the unverified #312/#313 trailing-mandate
+check into the same run.
+
+**Precondition, handled.** #191 (dependency resolution before scaffold accept) closed on 2026-07-21:
+`runSetupCommand` runs the profile alias `setup` before every build gate and #40 resolves it per
+toolchain. But `setup` is operator-declared, and the repo profile didn't declare one — so with
+`frontend/` cleared before each QA run, the now-firing terminal gate would run `npm run build` against
+an absent `node_modules` and fail on deps instead of on the code. Added
+`setup = "npm --prefix frontend install"` to `.correx/project.toml` (install, not `ci` — a fresh
+scaffold has no lockfile). The general case — a workspace whose operator declared no `setup` — is
+**#314** (toolchain-default fallback).
+
+**#40 follow-through** (commit `fb8141d6`). #40 (toolchain-aware command resolution — this repo hosts
+Kotlin at root *and* a Node app in `frontend/`, and one flat alias can't serve both) closed on
+2026-07-21 with `[commands.<toolchain>]` support in `6e844ef1`. The repo profile was never migrated:
+every flat alias still pointed at npm, so a Kotlin run's auto-gate would have run
+`npm --prefix frontend run build` — the latent misfire #40's own body predicted. Profile now carries
+`[commands.jvm]` + `[commands.node]` with jvm as the flat default. Parsing verified against
+`ProjectProfileLoader`; the gate prefers `<toolchain>.<alias>` and falls back to flat. #267's "re-scope
+#40" is now just the live confirmation.
+
+### Goal 3 + Goal 2 progress — 2026-07-26
+
+- **#307 ✅** (commits `c742656e`, `68b5392e`). `ContextAssembledEvent` records the injected manifest —
+  `{sourceType, sourceId, tokenEstimate, layer, role}` per entry, no content (that stays in CAS). Scope
+  check confirmed nothing existing carried it; `ContextTruncatedEvent` only reports drop counts. Emitted
+  at **all four** `contextPackBuilder.build` sites, not just the stage's first: the motivating question
+  ("did the steer-away hint fire on 7 consecutive turns?") is a per-rebuild question, and one event per
+  stage couldn't answer it. Turned out to be the delivery-tracking substrate #306 needed.
+- **#304 ✅** (commit `2b13f610`). Chose option (b) — recovery is a real second chance.
+  `detectRepeatedToolFailure` windows its fold to events after the most recent `FailureTicketOpenedEvent`
+  naming the stage. Route budgets are charged off the ticket event by the reducer, so the reset can't
+  open an infinite route-in/route-out cycle: 2+2 route cycles, each needing 6 fresh failures to re-trip.
+- **#309 ✅** (commits `ee69f9be`, `9db4e3dd`). `RecoveryFileLoopBreak.kt` — `fileRepairOutcomes`
+  correlates each `FileWrittenEvent` with the next `LspDiagnosticsCompletedEvent` per path, feeding both
+  consumers off one fold: the in-recovery guard (a path rewritten 3x without clearing opens
+  `FailureTicketOpened(gate=recovery_loop_break, escalated=true)` and fails terminally instead of
+  looping) and the ledger annotation in `buildRetryFeedbackEntry`, still `EntryRole.USER` with #313's
+  precedence untouched. **Correction landed on top:** the fold conflated "no diagnostic run since this
+  write" with "ran clean" — so the ledger said *"done, leave it"* about unverified files, and the breaker
+  could kill a run on the *absence* of evidence. Now a distinct `unchecked` state; the breaker requires
+  `!unchecked`.
+  - Left deliberately: the guard is terminal, not an operator-approval pause. Recovery is the last tier,
+    so there is nowhere to route; it opens the ticket for the record, then fails. Human-in-the-loop there
+    is a follow-up if wanted.
+- **#306 ✅** (commits `bc5afa51`, `f78c7f15`). Two halves, and only both together fix the report.
+  *Across stage entries:* the hint is keyed to its `RetryAttemptedEvent` occurrence, delivery derived by
+  folding prior `ContextAssembledEvent` manifests (`sourceType="unconfirmedFix"`, `sourceId=classKey`) —
+  no new state, pure fold (invariant #9). *Within one stage entry:* the guard alone was not enough —
+  `unconfirmedFixEntries` is called once at stage entry and its result folded into `accumulatedEntries`,
+  which every `pushBack` rebuild re-uses, so the hint rode into every turn regardless. That is the actual
+  7-turn symptom; the entry is now dropped once its first pack is built.
+  - Directions 2/3 from the ticket needed no code: `classKey` already derives from the current retry's
+    own class, and routing dead-ends carry `gate="stage"` while every other path carries its real gate,
+    so `"$gate:$signature"` can't collapse them. Locked in with a regression test rather than a rewrite.
+
+- **#299 ✅** (commit `c5289420`). `route()` now splits the two cases the old code conflated: a
+  capability **nobody was ever configured with** still fails fast, but a capability that *is*
+  configured whose candidates are all currently unhealthy gets a bounded wait (3 × 2s, each round
+  re-checking `refreshedHealth` rather than the TTL cache) before `NoEligibleProvider`. A crash-plus-
+  restart no longer collapses a retryable failure into a session kill.
+- **#300 ✅** (commit `bf362527`). Made health *gating* instead of reactive: new
+  `InferenceRouter.reportFailure(providerId, reason)` (default no-op) writes `Unavailable` straight
+  into the health cache, bypassing `healthCheck()`/TTL, and `SessionOrchestrator.kt:454` calls it from
+  the inference catch when `isConnectionLevelFailure(e)`. The next `route()` sees the drop
+  immediately instead of ~18s later. Recovery needs no extra path — TTL expiry or #299's bounded-wait
+  re-check picks the provider back up.
+
+**Goal 3 remaining:** none. #308 partly pre-empted by `ac460156` — a shell timeout is now recoverable
+and coaches `nohup &` detach, so there is no background-process registry to build unless a real gate
+needs one.
+
+**Goal 2 status calls — 2026-07-27.**
+- **#260 ✅** (commit `516af1ca`). Both halves are in the prompts: `discovery.md` requires inspecting
+  the whole decision surface and batching *all* operator-only questions after inspection (no
+  stop-at-first-uncertainty), and `analyst_freestyle.md` makes the `dod` artifact the handoff contract
+  — atomic, yes/no-checkable criteria, plus one criterion carrying the named task into the impl plan
+  and one per material failure path. #3 (architect re-plans on better input) fell out for free.
+- **#305 ✅** (commit `d52a94e5`). The ticket body was stale on two of three stores; traced each
+  against the tree before touching anything.
+  - *Store 1* shipped durable (`5df35879`) and was then deliberately **reverted to a memo**
+    (`12775d56`) — `SqliteObservationStore` was a second unsynchronized SQLite writer holding a fact
+    the log already carries (`FileWrittenEvent.path` + `postImageHash` + a pure `describe().render()`
+    over CAS bytes), i.e. an invariant-#1/#8 break. `descriptorMemo` keeps the perf win with none of
+    the risk. The "extend to the FileReadTool hot path" follow-up died with it: that path keyed on a
+    workspace-relative path while every consumer looks up the absolute one, so it never hit.
+  - *Store 2* was already complete in `unconfirmedFixEntries` — the `unconfirmed`/`falsified` states
+    below hard promotion, matched reactively on the retry's own `classKey`, made genuinely one-shot
+    by #306.
+  - *Store 3* was already built, but **deterministically rather than via the embedder**: intent
+    keyword Jaccard over a fold of (initial intent, locked plan, workflow completion). That beats the
+    planned embedder version on #8/#9 — pure fold, no environment read, so no recorded-retrieval
+    event is needed at all. Its one real gap was the consumer gate: `produces execution_plan` only,
+    so **discovery** — the stage the whole ticket is named after — still started cold. Now gated on
+    the produced artifact *kind* being a plan-shape consumer (`execution_plan` or `discovery`), with
+    a discovery-specific framing: the prior run's stage list read as a checklist of surfaces this
+    task-family touches, to inspect now rather than at stage 6.
+  - Left deliberately: tool categories in the plan shape (the plan said "stage sequence + tool
+    categories"). The sequence carries the signal; add the tool list only if a live run shows
+    discovery missing tooling it should have anticipated.
+- **#261 blocked by #267, correctly.** Its own body defers it until the simpler pipeline is proven on
+  a clean end-to-end run — which is the #267 acceptance run. Do #267 first.
+

+
+## Landed out-of-band — context message-type sweep (#312, #313)
+
+Not in the original three goals; pulled in on 2026-07-26 because it is upstream of Goal 1's gate
+verdicts and Goal 3's recovery tickets — both deliver their findings through the context builders
+this touched. #312 was listed as deferred-behind-#307; that turned out to be unnecessary, placement
+is statically determined by `PromptRenderer` + each producer's role, so no run ground truth was needed.
+
+**Rule established:** the system block carries only what does not change during a run. Anything the
+run mutates is a user message — a mutating system prefix defeats prompt caching, and models
+under-weight system-folded content against the trailing user turn. `role` = which chat message type,
+`layer` = pinning/prune eligibility; those were tangled and are now separate.
+
+- **#312** ✅ Audit — report at `docs/audits/2026-07-26-context-role-audit.md` (commit 514aeae7).
+- **#313** ✅ Implementation (commit a4f6cf05, `./gradlew check` green). Ten entries re-roled
+  SYSTEM→USER; trailing repair-mandate slot now emits exactly one mandate by precedence
+  (`recoveryTicket > retryFeedback > groundingFeedback > rejectionFeedback`) with `remainingDelta`
+  appended, so the slot stays scarce as members were added.
+- **Bug fixed en route:** the renderer's `layer == L0` clause was overriding role on four L0+USER
+  packs — `InferenceSummarizer`, `SemanticReviewerImpl`, `CapabilityGapReflectorImpl`, Talkie
+  session-naming — all four were sending a system-only request with **no user turn at all**.
+
+**Not verified live.** Needs one freestyle run to confirm the trailing mandate lands as intended.
+Fold into the Goal 1 acceptance run (#267) rather than spending a separate run.
