-Prompt and synthetic inbox ID reuse is now idempotent: reusing an ID within the same Session succeeds and returns the first admission, ignoring the retried payload, metadata, and delivery mode. Previously reuse with a differing payload failed with a conflict. Cross-Session and cross-type reuse still fail, and control items keep their operation-specific conflict behavior.

-Nested AGENTS.md instructions are re-injected after compaction. Previously the in-memory dedup claim outlived the synthetic message that compaction dropped from model-visible history, so nested instructions were silently lost for the rest of the process lifetime. The claim now only guards in-flight loads; the synthetic message metadata in durable history is the sole lasting ledger, so any history truncation (compaction, revert) self-heals on the next read in that subtree.

-Simplify interrupt continuation: the steer-scoped resume decision now lives in SessionExecution as a post-cleanup inbox check, and the run coordinator drops its continuation state machine. Wakes arriving during cancellation cleanup now restart a normal full drain, and interrupting an idle session with continue now resumes pending steering input. Recovery-applied moves now end with the same full wake as inbox-admitted moves, retrying any stranded inbox work at the new location. Interrupting with continue now also resumes a next-in-line control item: between-turn manual compaction and moves run under any drain scope, while queued prompts remain parked.

-Title generation and compaction summaries now build their model requests through the shared session request boundary, gaining unsupported-media filtering and image bounds while explicitly opting out of session context hooks: plugins that shape the agent conversation do not observe title or compaction requests. Title requests gain the fork-aware session prompt cache key, and compaction summaries in forked sessions reuse the fork root's prompt cache key instead of the fork's own.

+- Validate unknown values once at the boundary that owns them. Pass typed values inward instead of repeating `typeof value === "object"` and property-existence checks. Do not defensively revalidate values already guaranteed by a schema, constructor, or internal type.
 - Do not extract single-use helpers preemptively. Inline the logic at the call site unless the helper is reused, hides a genuinely complex boundary, or has a clear independent name that improves the caller.
 - Before adding complexity for a speculative or vanishingly unlikely race or security edge case, explain the concrete failure mode, likelihood, and complexity cost to the user and get their buy-in. Do not silently expand scope for theoretical robustness.

 - Prefer dynamic imports for heavy modules that are only needed in selected code paths, especially in startup-sensitive entrypoints. Destructure dynamic import bindings near the top of the narrowest scope that needs them so they read like normal imports. Avoid inline chains such as `await import("./module").then((mod) => mod.value())` or `(await import("./module")).value()`.

 - Keep `SessionRunner`, model resolution, tool registry, permissions, and filesystem Location-scoped. Omitted `Location.workspaceID` means implicit-local placement; explicit workspace identity remains reserved for future placement semantics.
 - Preserve one explicit `llm.stream(request)` call per Physical Attempt and reload projected history before durable continuation. A logical Step may use generic pre-output retries, one full-context retry after continuation rejection, incomplete-stream continuation, or one overflow-compaction rebuild. Generic retries retain the logical step number and do not consume another agent-step allowance. Do not delegate orchestration to an in-memory tool loop.
 - Keep local Session drains process-local until clustering is implemented. `SessionRunCoordinator` joins explicit same-Session resumes, coalesces prompt wakeups, and allows different Sessions to run concurrently. A write-ahead execution claim marks a process-local busy period for restart recovery: terminal completion, failure, or user interruption releases it, while shutdown interruption and process death preserve it. Startup recovery resumes claimed top-level Sessions with durable per-execution attempt accounting. The claim is a recovery marker, not clustered ownership, fencing, or an exactly-once guarantee.
- Keep delivery vocabulary explicit. Prompts steer by default. Steers deliver in enqueue order at safe step boundaries, stopping before compaction or move control items. At an idle boundary, steers take priority; otherwise exactly one queued item delivers before the runner reevaluates continuation. Inbox items may be cancelled or changed between queue and steer before delivery. Promoting new user input resets the selected agent's step allowance; a batch of steers resets it once.
+- Keep provider-specific native compaction mechanisms in `@opencode/ai` behind `LLMClient.compact`. `SessionCompaction` chooses a summary or native compaction from the model's `compaction` setting and owns route provenance, request shrinking, the retry policy, interruption, usage accounting, and checkpoint persistence.
+- Keep delivery vocabulary explicit. Prompts steer by default. At safe step boundaries, steered compaction takes priority up to the first steered move control; other steers retain enqueue order. At an idle boundary, steers take priority; otherwise exactly one queued item delivers before the runner reevaluates continuation. Inbox items may be cancelled or changed between queue and steer before delivery. Promoting new user input resets the selected agent's step allowance; a batch of steers resets it once.
 - One step is one logical LLM call; its durable record covers only the model-visible span. Do not write "provider turn", and do not use bare "turn" for a single call: "turn" is reserved for the future assistant-turn unit containing all steps from prompt promotion until the session would go idle.
 - Keep event replay ownership separate from clustered Session execution ownership.
 - Keep the Instructions algebra and built-ins in `src/instructions`; keep instruction producers with their observed domains, and keep Session History selection plus `InstructionState` and `InstructionEntry` persistence Session-owned. `InstructionDiscovery` observes ambient global and upward-project instructions. The runner composes built-ins, discovery, guidance, and entries explicitly in `loadInstructions`; there is no instruction registry.

+# V2 HTTP API audit checklist
+
+**Source:** `packages/protocol/openapi.json`  
+**Current endpoint count:** 139
+**Last regenerated:** 2026-09-13
+
+## How to use this checklist
+
+Review endpoints in document order. For each endpoint, select one disposition and capture rationale or follow-up work in Notes. Mark **Reviewed** only after the disposition is agreed.
+
+### Review criteria
+
+- Resource and operation naming
+- HTTP method and idempotency
+- Request parameters and location scope
+- Response shape and error taxonomy
+- Authentication and authorization
+- Current production consumers
+- Stability level: public, experimental, or internal
+- Whether the generated client API is intuitive
+
+### Disposition legend
+
+- **Keep:** ship unchanged as a supported V2 API
+- **Change:** retain after a defined contract change
+- **Remove:** exclude from the official V2 API
+- **Experimental-only:** retain outside the stable API commitment
+
+## Progress
+
+- [x] Group 1: Foundation and placement (4)
+- [x] Group 2: Configuration and capability catalogs (16)

+
+## Resolved during audit
+
+### [x] `POST /api/plugin/await-activation`
+
+- **Decision:** Remove
+- **Notes:** Activation timing is an internal server concern. Catalog reads remain non-blocking.
+
+### [x] Location response wrappers
+
+- **Decision:** Reduce generic endpoint response locations to `{ directory }`.
+- **Notes:** Full project metadata remains available from `GET /api/location`; no consumers used it from wrapped responses.
+
+### [x] `GET /api/health` and `GET /api/server`
+
+- **Decision:** Merge and rename
+- **Replacement:** `GET /api/info` with operation ID `server.info`.
+- **Notes:** Returns `version`, `pid`, and connection `urls`; readiness is conveyed by HTTP status.
+
+### [x] `GET /api/project/current`
+
+- **Decision:** Remove
+- **Replacement:** `GET /api/location`, using `project` from the response.
+- **Notes:** The endpoint duplicated `Location.Info.project`; production callers were migrated.
+
+### [x] `POST /api/workspace` and `DELETE /api/workspace/{workspaceID}`
+
+- **Decision:** Remove
+- **Notes:** Provider-backed workspaces are not part of the V2 HTTP contract and can be introduced later. Core and the embedded SDK retain internal workspace support.

+# Before: plain-text review

+Unchanged prose should remain quiet, not compete with changed rows.
+Replace one contiguous phrase: the original checkout experience stays here.
+Several little edits: red apple, cold tea, slow train.
+One character: ticket 7.
+before — the middle and the end remain unchanged.
+The start remains — before — the end remains.
+The start and the middle remain — before
+Punctuation only: hello, world!
+Whitespace only: one two three
+Trailing whitespace only.
+Delete this sentence without a replacement.
+
+This unchanged sentence separates a deletion from an addition.
+
+Long prose: The original checkout flow asks the reader to review the old confirmation message before proceeding through the receipt screen, while the unchanged middle of this deliberately long paragraph checks whether horizontal scrolling or line wrapping keeps small inline edits visible at a narrow viewport; the final old phrase appears near the far right edge.
+
+**Syntax-like Markdown** competes with `inline code`, [links](https://example.com/old), and _emphasis_.

+# File diff color tokens and CSS variables
+
+Inventory for this worktree's V2 web/desktop file viewer. Source inspection only; no colors or behavior changed. Includes diff-specific colors, syntax colors, and the selection/search/comment colors used inside the viewer—not every unrelated global app variable. Unified and split use the same color system.
+
+## Main controls and their wiring
+
+| Visual role | Renderer variable | OpenCode source |
+|---|---|---|
+| Neutral file background | `--diffs-bg` | `--opencode-diffs-bg`, falling back to `--color-background-stronger` (alias of `--background-stronger`) |
+| Default text | `--fg` / `--diffs-fg` | Registered theme foreground: `--text-base`; syntax spans override it |
+| Addition seed / gutter bar | `--diffs-addition-color` → `--diffs-addition-base` | `--syntax-diff-add` |
+| Deletion seed / gutter bar | `--diffs-deletion-color` → `--diffs-deletion-base` | `--syntax-diff-delete` |
+| Modified seed | `--diffs-modified-color` → `--diffs-modified-base` | `--syntax-diff-unknown` |
+| Added row | `--diffs-bg-addition`, `--diffs-bg-addition-override` | Mix of neutral background and addition seed |
+| Deleted row | `--diffs-bg-deletion`, `--diffs-bg-deletion-override` | Mix of neutral background and deletion seed |
+| Added inline span | `--diffs-bg-addition-emphasis`, `--diffs-bg-addition-emphasis-override` | Alpha of addition seed |
+| Deleted inline span | `--diffs-bg-deletion-emphasis`, `--diffs-bg-deletion-emphasis-override` | Alpha of deletion seed; softened on selected deletion rows |
+| Folded “unmodified lines” row | `--diffs-bg-separator`, `--diffs-bg-separator-override` | Mix of neutral background and `--diffs-mixer` |
+| Ordinary line numbers / fold text | `--diffs-fg-number`, `--diffs-fg-number-override` | Foreground/background mix |
+| Selection background | `--diffs-selection-base` → `--diffs-bg-selection` | `--v2-background-bg-accent` |
+| Selected line-number text | `--diffs-selection-number-fg` | `--v2-text-text-accent` |
+| Comment annotation background | `--diffs-comment-bg` | Alpha of `--v2-background-bg-accent` |
+| Search match / current match | CSS highlight backgrounds | Alpha of `--surface-warning-base` / `--surface-warning-strong` |
+
+**Important:** `--surface-diff-add-*`, `--surface-diff-delete-*`, and `--surface-diff-hidden-*` exist in the global theme, but are not the direct row/inline/fold controls in the current Pierre rendering path. The older/custom separator CSS in `components/file.css` does use `--surface-diff-hidden-base` and `--surface-diff-hidden-strong`.
+
+## OpenCode diff-specific theme tokens — complete families
+
+Each name below is a CSS custom property. Theme JSON override keys omit the leading `--`. Tailwind's `--color-…` aliases are defined in `packages/ui/src/styles/tailwind/colors.css` (for example `--color-surface-diff-add-base` → `--surface-diff-add-base`); these are aliases, not separate color decisions.
+
+### Surfaces
+
+```text
+--surface-diff-unchanged-base
+--surface-diff-skip-base
+--surface-diff-hidden-base
+--surface-diff-hidden-weak
+--surface-diff-hidden-weaker
+--surface-diff-hidden-strong
+--surface-diff-hidden-stronger
+--surface-diff-add-base
+--surface-diff-add-weak
+--surface-diff-add-weaker
+--surface-diff-add-strong
+--surface-diff-add-stronger
+--surface-diff-delete-base
+--surface-diff-delete-weak
+--surface-diff-delete-weaker
+--surface-diff-delete-strong
+--surface-diff-delete-stronger
+```
+
+### Text, icons, and highlighter diff seeds
+
+```text
+--text-diff-add-base
+--text-diff-add-strong
+--text-diff-delete-base
+--text-diff-delete-strong
+--icon-diff-add-base
+--icon-diff-add-hover
+--icon-diff-add-active
+--icon-diff-delete-base
+--icon-diff-delete-hover
+--icon-diff-modified-base
+--syntax-diff-add
+--syntax-diff-delete
+--syntax-diff-unknown
+```
+
+The built-in OpenCode theme maps `--syntax-diff-add` and `--text-diff-add-base` to `--v2-state-fg-success`, and their delete counterparts to `--v2-state-fg-danger`. Optional palette seeds `diffAdd` and `diffDelete` also exist for theme resolution; they are theme inputs, not CSS variable names, and built-in overrides can supersede generated results.
+
+## Syntax foreground tokens
+
+```text
+--syntax-comment
+--syntax-regexp
+--syntax-string
+--syntax-keyword
+--syntax-primitive
+--syntax-operator
+--syntax-variable
+--syntax-property
+--syntax-type
+--syntax-constant
+--syntax-punctuation
+--syntax-object
+--syntax-success
+--syntax-warning
+--syntax-critical
+--syntax-info
+--syntax-unknown
+```
+
+`--syntax-unknown` is referenced by the registered highlighter, but no definition was found in the current UI theme sources: treat it as an unresolved reference, not an existing resolved theme token. `--syntax-success` is available globally, although not directly used by that registered theme's current token-color rules.
+
+Built-in syntax overrides additionally reference `--v2-text-text-muted`, `--v2-pink-800`, `--v2-green-800`, `--v2-orange-800`, `--v2-purple-800`, and `--v2-red-800` (with separate dark/light resolutions). Other syntax tokens use the ordinary text tokens or theme-resolved colors.
+
+## Pierre renderer color variables — complete relevant inventory
+
+These come from the installed `@pierre/diffs` **1.5.1** stylesheet plus OpenCode's injected CSS. `*-override` variables are hooks; other variables include derived outputs and internal implementation details, not independent OpenCode theme tokens. Some optional hooks are unset by default.
+
+| Group | Variables |
+|---|---|
+| Base | `--diffs-bg`, `--diffs-fg`, `--diffs-mixer`, `--opencode-diffs-bg`, `--bg`, `--fg` |
+| Theme foreground/background variants | `--diffs-light`, `--diffs-dark`, `--diffs-light-bg`, `--diffs-dark-bg` |
+| Neutral backgrounds | `--diffs-bg-buffer`, `--diffs-bg-buffer-override`, `--diffs-bg-context`, `--diffs-bg-context-override`, `--diffs-bg-context-gutter`, `--diffs-bg-context-gutter-override`, `--diffs-bg-separator`, `--diffs-bg-separator-override` |
+| Number / conflict-marker foreground | `--diffs-fg-number`, `--diffs-fg-number-override`, `--diffs-fg-number-addition-override`, `--diffs-fg-number-deletion-override`, `--diffs-fg-conflict-marker`, `--diffs-fg-conflict-marker-override` |
+| Addition seed | `--diffs-addition-base`, `--diffs-addition-color`, `--diffs-addition-color-override`, `--diffs-light-addition-color`, `--diffs-dark-addition-color` |
+| Deletion seed | `--diffs-deletion-base`, `--diffs-deletion-color`, `--diffs-deletion-color-override`, `--diffs-light-deletion-color`, `--diffs-dark-deletion-color` |
+| Modified seed | `--diffs-modified-base`, `--diffs-modified-color`, `--diffs-modified-color-override`, `--diffs-light-modified-color`, `--diffs-dark-modified-color` |
+| Renderer fallback colors | `--diffs-added-light`, `--diffs-added-dark`, `--diffs-deleted-light`, `--diffs-deleted-dark`, `--diffs-modified-light`, `--diffs-modified-dark`, `--diffs-warning-light`, `--diffs-warning-dark` |
+| Added row/gutter/inline | `--diffs-bg-addition`, `--diffs-bg-addition-override`, `--diffs-bg-addition-number-override`, `--diffs-bg-addition-emphasis`, `--diffs-bg-addition-emphasis-override` |
+| Deleted row/gutter/inline | `--diffs-bg-deletion`, `--diffs-bg-deletion-override`, `--diffs-bg-deletion-number-override`, `--diffs-bg-deletion-emphasis`, `--diffs-bg-deletion-emphasis-override` |
+| Selection | `--diffs-selection-base`, `--diffs-selection-number-fg`, `--diffs-bg-selection`, `--diffs-bg-selection-override`, `--diffs-bg-selection-number`, `--diffs-bg-selection-number-override`, `--diffs-bg-selection-text` |
+| Hover | `--diffs-bg-hover-override`, `--diffs-hover-mix-target` |
+| Comments / decoration | `--diffs-comment-bg`, `--diffs-annotation-bg`, `--diffs-decoration-bg`, `--diffs-decoration-bar-color` |
+| Internal background pipeline | `--diffs-computed-decoration-bg`, `--diffs-computed-diff-line-bg`, `--diffs-computed-selected-line-bg`, `--diffs-computed-editor-active-line-bg`, `--diffs-computed-hovered-line-bg`, `--diffs-line-bg` |
+| Internal mix targets | `--diffs-diff-line-mix-target`, `--diffs-selection-mix-target`, `--diffs-selection-emphasis-mix-target` |
+| Per-token light/dark colors | `--diffs-token-light`, `--diffs-token-dark`, `--diffs-token-light-bg`, `--diffs-token-dark-bg` |
+| Conflict backgrounds (library support; not exercised by the fixture) | `--conflict-bg-current-header-override`, `--conflict-bg-current-number-override`, `--conflict-bg-current-override`, `--conflict-bg-incoming-header-override`, `--conflict-bg-incoming-number-override`, `--conflict-bg-incoming-override` |
+
+Related mix controls are **percentages, not colors**: `--mix-light`, `--mix-dark`, `--mix-deco-light`, `--mix-deco-dark`, `--mix-selection-light`, `--mix-selection-dark`, and `--diffs-editor-active-line-source-mix`.
+
+## Other color tokens used inside the file viewer
+

+- Background fallback: `--background-stronger`, `--color-background-stronger`; comment actions also use `--background-base`.
+- Selection: `--v2-background-bg-accent`, `--v2-text-text-accent`.
+- Search: `--surface-warning-base`, `--surface-warning-strong`.
+- Custom fold UI: `--surface-diff-hidden-base`, `--surface-diff-hidden-strong`, `--icon-strong-base`; `--text-mix-blend-mode` affects compositing but is not a color.

+- Comment shadows (composite shadow tokens, not single colors): `--shadow-xs`, `--shadow-xs-border-focus`, `--shadow-xxs-border`, `--shadow-xs-border-select`.

+- `diff-color-fixture/README.md` is tracked and unchanged.
+- Only fixtures changed. No renderer, token, behavior, formatter, push, PR, or deployment changes.
+
+## Actual UI and how to open
+
+The captures use the real source-backed OpenCode web app from this worktree, connected to the existing V2 background server (2.0.21). No mocked data or copied renderer. The app dev server remains available at `http://127.0.0.1:4444` and was started with `VITE_OPENCODE_SERVER_PORT=49374 bun run dev -- --port 4444` from `packages/app`. Existing app/server processes were not restarted.
+
+Open:
+
+`http://127.0.0.1:4444/server/aHR0cDovLzEyNy4wLjAuMTo0OTM3NA/session/ses_f085f0176ffeiNj9364c2CnHqm`
+
+Alternatively open this session in OpenCode Desktop; its location is now this worktree. Toggle Review, choose **Git changes**, and select a fixture file. This UI calls the working-tree source “Git changes,” not “Uncommitted changes.” Use the file-tree toggle if the list is hidden. Unified/Split controls are in the review toolbar.
+
+Captures: 1440 × 1000 CSS pixels, default OpenCode (`oc-2`) theme, system light/dark media preference. Chat pane was resized to its minimum and the file tree hidden to give the diff about 964 pixels. Wrapping was enabled by the production viewer. Close-ups below are unchanged crops of those screenshots, not re-rendered mockups.

+## Case notes
+
+| Case | Unchanged sections | Red/green scan | Inline emphasis | Text readability |
+|---|---|---|---|---|
+| Single additions/deletions/replacements, adjacent rows (`01`, `03`) | Neutral background recedes; unchanged syntax can still draw the eye | Light is clearer; dark relies more on gutter bars and line numbers | Distinct but restrained | TS strings stay green even on red deletion rows, competing with change meaning |
+| Contiguous versus separated edits (`01` lines 11–12; long line) | Common words inside an inline span do **not** recede | Row direction is still clear from gutter and tint | Current production `word-line` rendering joins separated edits into one broad span; multiple independent highlight islands were not available in this state | Broad wrapped emphasis adds visual weight without improving precision |
+| One-character, start/middle/end edits (`01` lines 13–16; `03`) | Surrounding text remains readable | Large words are easy to find; one-character changes need deliberate attention | One-character patch is visible but easy to miss at normal scan speed | No observed loss of string readability |
+| Punctuation and spaces/indent/trailing spaces (`01` lines 17–20; `03`) | Quiet surroundings | Row markers expose that something changed | Small semicolon/space blocks are visible on close inspection; blank blocks give little explanation without visible whitespace glyphs | Readable; punctuation has less salience than colored keywords |
+| Isolated hunks and collapsed sections (`02`) | Neutral context recedes; three bars visible simultaneously in split | Distinct isolated rows, but dark tints are weak | Small changed-word blocks don't dominate rows | Fold-label text is unusually faint, especially dark; context comments are clearer than the fold labels |
+| TS/TSX types, keywords, comments and JSX (`01`) | Syntax in unchanged rows remains fairly prominent | Pink keywords/green strings compete with the red/green layer | Emphasis is generally subordinate; the long merged span is the exception | Comments/strings/types readable overall; muted JSX words like “old,” “new,” and button text are weak on tinted/highlighted backgrounds in dark mode |
+| Markdown and wrapped prose (`03`) | Plain prose is visually quieter than code | Light tints are clearer than dark | Long spans emphasize unchanged middle words as well as changes | Plain prose remains readable but looks muted; bold/heading syntax draws attention more strongly than small edit spans |
+| Long/wrapped lines (`01`, `03`) | Common middle text is swallowed by merged emphasis | Tinted multi-line blocks are apparent | Broad highlights repeat across wraps and visually dominate small changes | Wrapping works in unified and split; side-by-side requires more vertical scanning |
+| File beginning/end (`01`, `02`, `03`) | Neutral surrounding rows recede | Changes shown at first/last lines | Same inline behavior as middle edits | Readable |
+| Dense larger file (`04`: 63 lines, 40 replacements / 80 changed rows) | **Not visually checked** | Not checked | Not checked | Fixture ready for review |

+
+## Specific problems to carry into a later design pass
+
+1. Dark row backgrounds have weak separation from neutral context; syntax hue is often more salient than change direction.
+2. Green string syntax appears on deleted rows too, weakening red/green semantic scanning. Pink keywords similarly attract attention independently of change status.
+3. Collapsed-section labels recede too far: their subdued text is harder to read than surrounding context comments.
+4. One-character, punctuation, and whitespace highlights are easy to miss without focused inspection. Their issue is subtlety/size, not overpowering brightness.
+5. Muted JSX text on dark inline backgrounds is less readable than the surrounding syntax. Broad inline spans across wrapped lines add disproportionate visual mass.
+
+The merged-span behavior is a renderer observation, not a proposed color fix. No final values selected, no fixes implemented, and no contrast-ratio compliance claim made.
+
+## GitHub Desktop comparison boundary
+
+The referenced discussion/image was not included in this session. A precise comparison to that direction is therefore **not verified**. As a provisional hierarchy comparison only: quiet context → recognizable changed row → localized stronger inline emphasis is the useful target. OpenCode already keeps ordinary inline backgrounds subordinate to rows, but dark row separation, syntax competition, faint fold controls, and merged broad spans weaken that hierarchy. This is not a claim that the specific GitHub Desktop reference was inspected.
+
+Scope was intentionally stopped after the user's request to do less. No full lint/typecheck was run: these are standalone visual examples with deliberate whitespace/formatting changes, not product code.
