chore: ignore frontend/, the untracked Vite QA client

The web-UI QA app at the repo root is a live-QA surface, not a tracked module. Without the rule
every run of the experiment or the stack leaves the working tree dirty, which blocks the PR helper.

 - `GET /metrics/tool-reliability` — per-model tool-call validity across the event log (`ToolReliabilityInspectionService`); groundwork for capability-aware routing
+- `GET /metrics/failure-attribution` — terminal-failure attribution across the event log (`FailureAttributionInspectionService`): count and share per `FailureAttribution` layer, the UNKNOWN share, the preserved reasons behind each row, and the `FailureTicketOpened` categories from the same sessions. Read-only: events recorded before `WorkflowFailedEvent.attribution` existed are classified at read time by `FailureAttributor` and reported as `inferred`, never written back.
 - Optional `[git]` transport creates `run/<sessionId>` from a server-local checkout and pushes it at terminal state; clients review with ordinary Git and never supply a remote URL as `cwd`.
 - Repo-map L3 embeddings use bounded, recorded source descriptors (module/package, imports, leading purpose comment, symbols); raw file bodies are never embedded. Their versioned `repomap:v2` namespace forces a one-time re-embed when the semantic document format changes.
 - At boot, `tools.workspace_root` is the authoritative default tool jail. Every session records its own resolved workspace binding; repo maps, project memory, profile/instruction snapshots, and git run branches use that binding and skip unbound sessions. `[project]` never supplies a workspace root.

 - Hard Invariant #9: all `WorldProbe` calls record observations as events. Replay reads those recorded events — it must not call `WorldProbe` again.
 - Hard Invariant #5: every tool call must be assessed before execution. Assessment result is recorded as `ToolCallAssessmentEvents` in `core:events`.
 - New rules implement `ToolCallRule` and are registered in `WorkspacePolicy`. Do not add rule logic directly to `ToolCallAssessor`.
+- Resolve every model-supplied path through `ToolPath.resolve` (`core:tools`) — the one canonical normalization rule, shared with the filesystem tools. A rule that resolves paths itself will judge a different path than the tool operates on (the `~` bug: `~/x` resolved to `<workspace>/~/x`, so a real home-directory file was reported as a non-existent in-workspace file and the out-of-workspace prompt never fired).
+- `ReadBeforeWriteRule` exempts calls declaring `ToolCapability.CONTENT_FROM_SOURCE` — every byte written comes from an existing source object, so there is no model-authored content to clobber with, and requiring a read of a copied binary is unsatisfiable. The exemption keys on that declared PROVENANCE, never on the presence of a `SOURCE_PATH` parameter: a transform or import tool may name a source and still write model-controlled output, and must stay gated. It lives in `appliesTo`, so `ToolCallAssessor` skips the rule entirely.

+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. |
+| `criticFeedback` / `neededArtifact` | Context.kt:444 | L1/USER → **inline** | keep | Stage *input*, not a mid-loop correction. Trailing slot should not carry inputs. |
+| `unconfirmedFix` | Concepts.kt:107 | L1/USER → inline | keep | Advisory, not a mandate. |
+| `toolResult` (incl. failures) | Execution.kt:351/564, ToolExec.kt:215… | L2/TOOL → inline tool turns | **keep** | Routine self-correctable — "target not found", READ_BEFORE_WRITE, patch misses. Lifting these floods the user channel and destroys the effect. Escalation happens on *repetition*, and that path already exists (`STAGE_LOOP_BREAK_GATE` → `recoveryTicket`); #309's loop-breaker is the right place, not the per-failure site. |
+| `assistantToolCall` | ToolExec.kt:205… | L2/ASSISTANT → inline | keep | Correct. |
+| `initialIntent` | Context.kt:162 | L1/USER, but **L0 ⇒ system fold**… no: L1/USER → inline | keep | Doc comment at Context.kt:148 claims "pinned L0 SYSTEM"; code says L1/USER. Comment is stale — **fix the comment**, not the code (L1/USER is right). |
+| `clarificationAnswer` | Context.kt:205 | L0/SYSTEM → system fold | keep, flag cache | Mutable mid-run (grows per clarification) inside the cached prefix. Low frequency; acceptable. |
+| `schemaInstruction`, `systemPrompt`, `operatingGuidance`, `projectProfile`, `agentInstructions`, `operatorProfile`, `claimedTask`, `promotedConcept`, `verifiedBaseline`, `successfulPlanShape` | various | L0/SYSTEM → system fold | keep | Stable per stage. Correct and cache-friendly. |
+| `agentPrompt` | Execution.kt:120/147 | L1/USER → inline | keep | The stage task. |
+| `repoMap`, `docsCatalog`, `relevantFiles`, `decisionJournal` | Context.kt:289/376, ContextFeedback.kt:245, Execution.kt:189 | L3/USER → inline | keep | Reference material; #290 already moved these out of the system fold. |
+
+## 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.

+
+## 1. Scope collapse at the analyst (closed by #699)
+
+Discovery settled 8 scope items (artifact `8053f0d7`): session driver, sessions list,
+workflow listing, event log viewer, artifacts/timeline, ideas board, profiles, configuration.
+
+The analyst emitted 4 criteria (artifact `5d46f805`), every one `part: "Project Foundation"`.
+Its summary reads *"Initialize the Correx web-ui project with the required tech stack."* The
+architect planned against the shrunken DoD (`13d08806`): `scaffold_frontend`,
+`install_styling_and_ethos`, `configure_tanstack_query`, `final_review`. Its `goal` field
+never mentions a view.
+
+Nothing downstream sees discovery again. Implementer stages receive `neededArtifact: dod` and
+nothing else, so the loss is total and silent from seq 236 onward.
+
+All three plan gates passed, because all three grade structure and the structure was sound.
+
+Closed by `ScopeCoverage` (#699, commit `700f59ef`, 19:56 the same day). Stated ceiling holds:
+it catches a dropped index, not a weak criterion.
+
+## 2. The build gate ran the wrong toolchain (#705, open)
+
+[`SessionOrchestratorGates2.kt:156-178`](../../core/kernel/src/main/kotlin/com/correx/core/kernel/orchestration/SessionOrchestratorGates2.kt#L156-L178):
+
+- `sessionProducedBuildTarget(sessionId)` is **session-scoped** and turns the gate on.
+- `stageProducedToolchain(sessionId, stageId)` is **stage-scoped** and returns null when the
+  stage wrote no files.
+- `commandFor(profileCommands, null)` then falls back to the flat `build` alias.
+
+`final_review` is a reviewer. Its tools are `[file_read]` and the plan set
+`build_expectation: "none"`. It wrote nothing, so the toolchain lookup returned null and the
+gate ran `./gradlew assemble` against a run whose every write was `frontend/**`. The correct
+command, `node.build` = `npm --prefix frontend run build`, had already passed at seq 951, 1286
+and 1683.
+
+The failure it produced was environmental:
+
+```
+> Could not resolve io.ktor:ktor-client-websockets:3.0.3.
+  > No cached version ... available for offline mode.
+```
+
+That is `~/.gradle/init.d/offline.gradle` on workpc, outside the workspace jail, predating the
+session.
+
+Cost: 4 retries plus a recovery detour, seq 1694 to 2733. That is **32.5 min, 33% of wall
+clock**, and the run's death.
+
+Fix: when the stage produced no toolchain, fall back to the session's toolchain (the same
+manifest `sessionProducedBuildTarget` already reads) before the flat alias. Two lookups
+deciding one command must share a scope.
+
+## 3. The harness destroyed a correct diagnosis (#707, open)
+
+Only 4 of 274 inference rounds returned any text at all (§5). Three of them are this finding.
+
+- **seq 1994**: *"The build failed because the Gradle environment is in offline mode... The
+  `org.gradle.offline=true` flag is present in `~/.gradle/init.d/offline.gradle`."* Correct
+  root cause, reached in about ten minutes.
+- **seq 2306**: *"Since `~/.gradle/init.d/offline.gradle` was not found, I will check for global
+  Gradle properties..."* The model **retracted the correct answer**, because at seq 1793
+  `file_read ~/.gradle/gradle.properties` returned `[REFERENCE_EXISTS] ... does not exist. Do
+  NOT keep retrying`. The tool layer does not expand `~`, and the path is outside the jail
+  regardless. The guard reported a true thing as false.
+- **seq 2715**: *"the DoD criteria do not require a successful backend build... the frontend
+  build passed... I cannot fix the backend dependencies, it's out of scope. However, since the
+  PROJECT build gate is a hard gate, I must reject it."*
+
+Right three times, and wrong-footed each time by the harness.
+
+The structural gap: every verdict the reviewer can emit (`approved`, `changes_requested`,
+`rejected`) routes back into the agent. There is no way to say *this failure is not
+attributable to this run*. `FailureTicketOpened` fired correctly at seq 2374 after 6 identical
+failures, routed to `recovery`, and recovery routed straight back (`RefinementIteration`,
+seq 2584).
+
+The retry feedback closed with *"Do not re-discover unrelated files before it builds."*
+The harness forbade the only move that would have worked.
+
+## 4. Ten-turn amnesia inside a mostly empty window (#706, open)
+
+176 `ContextTruncated` events, every one L2, `entriesDropped` climbing to 40+ and pinning.
+
+| stage | truncations | max dropped |
+|---|---|---|
+| discovery | 14 | 28 |
+| scaffold_frontend | 40 | 40 |
+| install_styling_and_ethos | 20 | 40 |
+| configure_tanstack_query | 21 | 16 |
+| final_review | 62 | 42 |
+| recovery | 16 | 32 |
+
+[`DefaultContextPackBuilder.kt:380`](../../core/context/src/main/kotlin/com/correx/core/context/builder/DefaultContextPackBuilder.kt#L380)
+uses `CompressionStrategy.Conversation()`. The default is `keepLast = 10`
+([`CompressionStrategy.kt:7`](../../core/context/src/main/kotlin/com/correx/core/context/compression/CompressionStrategy.kt#L7)).
+L2 holds **5 tool-call/result pairs**. The assembled pack at round 31 of `scaffold_frontend`
+(seq 599) confirms it. It carries 4 L0 entries, 2 L1, 3 L3, and 10 L2, exactly the last ten.
+
+**The window is not full.** Those same packs run 1.7k to 13k tokens, median 5.3k. The cap is
+entry count, not tokens, so the model is starved at 5k while a local model's context sits
+mostly idle.
+
+Consequence, measured: **76 byte-identical repeat calls**, 29% of all tool invocations.
+
+| repeats | stage | call |
+|---|---|---|
+| 9 | final_review | `list_dir {"path":"frontend"}` |
+| 7 | scaffold_frontend | `list_dir {"path":"frontend/"}` |
+| 6 | final_review | `file_read {"path":"gradle.properties"}` |
+| 5 | scaffold_frontend | `file_read {"path":"frontend/package.json"}` |
+| 4 | final_review | `shell ./gradlew assemble --no-configuration-cache` |
+
+The `decisionJournal` is the only memory surviving eviction. Its complete content at the end of
+the run:
+
+```
+- Goal: Write a web-ui for Correx. ...
+- scaffold_frontend: 1 retry, resolved — stage completed
+- configure_tanstack_query: 1 retry, resolved — stage completed
+- final_review: 3 retries, resolved — stage completed
+```
+
+Bookkeeping, not knowledge.
+
+Preferred fix is not a larger `keepLast` (it costs local-inference latency and still forgets).
+Add a deterministic **action ledger**. One line per tool call for the stage: tool, target,
+exit, short result hash. Never evicted. 258 calls at roughly 12 tokens is about 3k tokens for
+a whole run. That is cheaper than the duplicates it removes, and it carries the "already
+tried, same failure" signal no window size provides.
+
+Related: the plan set `kind: "process_result"` on every stage, which silently disables the
+`file_written` manifest injection
+([`SessionOrchestratorContext.kt:458`](../../core/kernel/src/main/kotlin/com/correx/core/kernel/orchestration/SessionOrchestratorContext.kt#L458)
+builds it only for `file_written` slots). A feature built to prevent this thrash was switched
+off by one planner field.
+
+## 5. There was no chain of thought
+
+**270 of 274 inference rounds returned an empty response body** (blake3
+`af1349b9...`, the empty string). Per stage: discovery 25/25, analyst 9/9, architect 1/1,
+scaffold_frontend 62/62, install_styling 31/31, configure_tanstack 32/33, final_review 83/86,
+recovery 27/27.
+
+Every assistant message in the assembled prompts is a bare function call with no content. The
+system prompt instructs *"make one coherent step per response."*
+
+The loop reduces to this. Context in, one tool call out, no reasoning, no plan, no self-check,
+with a 10-turn memory (§4) at temperature 1.0 (§6). The 29% repeat rate is what that
+combination produces. Surfacing reasoning is already tracked as #298. This finding is that
+none was produced to surface.
+
+## 6. Temperature 1.0 on structured arguments (#710, open)
+
+[`Main.kt:435-451`](../../apps/server/src/main/kotlin/com/correx/apps/server/Main.kt#L435-L451)
+sends `[sampling] temperature = 1.0, top_p = 0.95, top_k = 64` on **every** stage inference.
+Chat-quality settings applied to fields where exactly one string is correct.
+
+| seq | emitted | intended |
+|---|---|---|
+| 277 | `create_vite@latest` | `create vite@latest` |
+| 465 | `npm_prefix=frontend` | `npm --prefix frontend` |
+| 1302 | `npm_install_package` | `npm install <package>` |
+| 2060 | `./gradlew_` | `./gradlew` |
+| 2708 | `gradlew` | `./gradlew` |
+
+Space-to-underscore substitution on an argv field is sampling noise. correx already sends a
+per-request `GenerationConfig`, so the override is per-call. Keep 1.0 for artifact and review
+prose. Go near-greedy when the response is constrained to tool calls. #303 repairs these after
+the fact. Not emitting them is cheaper.
+
+**Same task, second half: files are copied through the token stream.** There is no `file_copy`
+tool. `ethos-icons.svg` moved by a `file_read` of 6124 characters, then a `file_write` of 6845
+characters of tool-call arguments. A `READ_BEFORE_WRITE` rejection round came first (seq 540),
+when the model tried to write before reading. About 6 rounds and 13k tokens for two static
+assets, at temperature 1.0, with silent corruption possible. The project profile says *"COPY
+design-system/ethos.tokens.css and ethos-icons.svg into the project and import them, do NOT
+read their contents."* The toolset offers no way to obey that instruction.
+
+## 7. The plan contradicts itself, and the kernel sides against the model (#711, open)
+
+The architect emits a stage's `prompt` and its `writes` manifest independently. They disagreed
+twice, and the kernel enforces `writes`.
+
+- `install_styling_and_ethos` prompt step 4: *"Copy ... into `frontend/src/assets/ethos/`."*
+  Manifest: `[tailwind.config.js, postcss.config.js, src/index.css]`. Result at seq 1086:
+  `[PATH_OUTSIDE_MANIFEST]`.
+- `configure_tanstack_query` prompt step 2: *"Create a `QueryClient` instance and a wrapper
+  component."* Manifest: `[frontend/src/lib/query-client.ts]`. Blocked at seq 1321.
+  `QueryClientProvider.tsx` was then written 8 times.
+
+Both fields are already parsed by the plan-compile gate, so this is a string check over paths
+the prompt itself spells out.
+
+## 8. The stage prompt never updates (#709, open)
+
+Verified against the assembled prompt for round 31 of `scaffold_frontend` (artifact
+`47ebf7b0`). The system message still read:
+
+> Use the `shell` tool to initialize a new React + TypeScript project using Vite in the
+> `frontend/` directory. Run `npm create vite@latest frontend -- --template react-ts` ...
+
+The project had existed for 30 rounds. The instruction is a fixed string from the execution
+plan, and nothing recomputes it against what exists. Combined with §4, the model's strongest
+signal every round is an order to redo step one.
+
+The plan's stage prompts are literal command transcripts written from training memory, and both
+were wrong:
+
+- `npx tailwindcss init -p`. `npx` is **blocked by tool policy**, rejected at seq 329 and 988.
+  The policy message helpfully names the alternative. A plan-compile lint rejecting a plan that
+  names a forbidden executable is roughly ten lines.
+- `npm install -D tailwindcss postcss autoprefixer` plus `tailwind.config.js` is the **Tailwind
+  v3** procedure. `npm install tailwindcss` now resolves v4, where the PostCSS plugin moved to
+  `@tailwindcss/postcss`. That is the build failure at seq 609 verbatim, and 22 rounds of
+  thrash followed it.
+
+## 9. Ninety-four approvals that carried no information (#712, open)
+
+Every `ApprovalDecisionResolved` in the run is `APPROVED` with `reason: null` and
+`userSteering: null`. Pause durations: p50 13.6 s, p90 19.0 s, max 20.3 s. Total **19.0 min,
+19% of wall clock**.
+
+By tool: `shell` T2 x63, `file_write` T2 x13, `file_edit` T3 x10, remainder task and delete
+calls.
+
+Two problems. The gate is priced per tool call, so it charges 94 interrupts for one operator
+intention. The attention also lands in the wrong place. All 94 chances to intervene were
+spent on "may I run `npm install`". The decision that determined the outcome (seq 236, §1)
+had no operator checkpoint at all.
+
+Auto-approving reads and writes inside the stage's declared `writes` manifest costs nothing in
+safety, because `PATH_OUTSIDE_MANIFEST` already enforces that boundary. It returns most of the
+19 minutes.
+
+## Waste breakdown
+
+258 tool calls. 110 wasted, counting each call once (repeat, failed, or policy-rejected).
+
+| stage | waste / total | |
+|---|---|---|
+| discovery | 2 / 24 | 8% |
+| analyst | 1 / 8 | 12% |
+| scaffold_frontend | 26 / 60 | 43% |
+| install_styling_and_ethos | 11 / 30 | 37% |
+| configure_tanstack_query | 9 / 31 | 29% |
+| **final_review** | **55 / 79** | **70%** |
+| recovery | 6 / 26 | 23% |
+
+Context composition across all 279 assemblies: `toolResult` 47.9%, `projectProfile` 8.4%,
+`assistantToolCall` 8.1%, `decisionJournal` 6.8%, `retryFeedback` 5.4%. By layer: L2 56.0%,
+L0 18.0%, L1 13.2%, L3 12.9%.
+
+## Ranked remediation
+
+inference, from this run's own timings:
+
+1. **Baseline every gate command at session start (#708).** One build at t=0. A command already
+   red before the agent touched anything reports `pre-existing` and never fails a stage.
+   Recovers `final_review` plus most of `recovery`. **~40 min.**
+2. **Fix the toolchain scope mismatch (#705).** One line. Prevents the same 40 minutes by an
+   independent route. Do both.
+3. **Deterministic action ledger (#706).** ~16 min of duplicate calls, plus the loops they feed.
+   Raising `keepLast` alone does not fix it.
+4. **Auto-approve inside the declared manifest (#712).** **~17 min.**
+5. **Split the sampling config (#710).** Near-greedy for tool-call rounds.
+
+Items 1, 3 and 4 account for roughly 70 of the 99 minutes.
+
+## The structural point
+
+Every gate in this run was local. Each asked whether a stage did its stage correctly. None
+asked whether the run was still building the requested thing, until `final_review` at minute 90
+graded against the already-collapsed DoD.
+
+The path from intent to work is five lossy model summarisations: intent, discovery, DoD, plan,
+stage prompt. Only the last link was ever checked. #699 now checks the DoD-to-discovery link,
+which is the one that broke here. The general shape remains.
+
+The cheap version needs no model. The intent names eight views. After three of four stages,
+`FileWritten` holds nine files and none is a view. That comparison is a set difference over
+recorded events and costs nothing. It would have fired at minute 25, not failed silently at
+minute 99.
+
+The deeper item, for #168: this run produced a genuinely valuable artifact and discarded it. A
+local model correctly diagnosed a Gradle offline-mode misconfiguration in ten minutes from
+build output alone. That knowledge existed at seq 1994 and was gone by seq 2306. A guard
+reporting a real file as missing erased it. The event log still has it. Nothing reads it back.
+
+## Verification and scope
+
+- fact: every number above is derived from `events` rows for session `954da1a9` and from CAS
+  artifacts resolved through `~/.config/correx/artifacts/index.sqlite`. No inference re-run.
+- fact: `ScopeCoverage` (#699) landed at 19:56 on 2026-08-11, after this session ended at
+  13:31. It was not active during the run.
+- inference: the `./gradlew assemble` failure is attributed to `~/.gradle/init.d/offline.gradle`
+  on workpc. The build output names offline mode and an uncached `io.ktor:ktor-client-websockets`.
+  The file itself was not read during this analysis.
+- unknown: whether the 94 approvals were resolved by a human operator or by an auto-approver.
+  The tight 13-20 s clustering suggests a poll interval. No event records the decider.
+- This post-mortem implemented no fixes. It filed Vikunja #705 through #712.
