Subject: [PATCH 001/117] feat(app): tasks panel for background subagents and
 shell tools

Adds a Tasks tab to the session side panel (review surface) showing live background work for the current session: subagent cards joined by the task tool's metadata.sessionId (child session id), foreground shell cards, needs-input state from pending permissions, nested (+N) counts, elapsed timers, click-to-open transcript, per-task stop, and auto-open on 0->N. Derives everything from synced reactive stores (no fetching/polling).

Subject: [PATCH 005/117] feat(app): english fallback for new tasks keys across
 locales

Parity test requires every English key present in all locales. Real translations land via the locale sync flow; until then English source stands in (established precedent: 128 identical-EN keys in de.ts).

Subject: [PATCH 007/117] feat(opencode): task tool accepts explicit
 provider/model per subagent

New optional 'model' param as 'providerID/modelID' (e.g. 'openrouter/deepseek/deepseek-chat'). Resolution: param > agent model > parent model. Provider part selects credentials ambiently (OAuth subscriptions, API keys, custom provider aliases for extra keys). Malformed values fail fast. Docs in task.txt. Tests: forward + reject + unchanged defaults.

Subject: [PATCH 008/117] feat(opencode): model-scoped task permissions for
 subagent allowlist

When the session carries task rules with model patterns (pattern containing '/'), the resolved provider/model is added to the permission ask patterns and metadata. Otherwise behavior is unchanged (no extra prompt). Denied models surface the session ruleset so the caller can retry with a listed model.

Subject: [PATCH 010/117] feat(app): subagent model allowlist picker dialog

DialogSubagentModels mirrors DialogManageModels (Dialog + searchable grouped List + per-model Switch, live-apply). Reads effective state from session permission rules, appends allow/deny task rules via session.update (server merges, last match wins; first constraint writes the star-slash-star deny baseline). Opened via tasks.models command. English fallback across locales; real translations land via locale sync.

Subject: [PATCH 011/117] feat(app): subagent-models control in composer
 toolbar

Adds the subagent model picker next to the session model and reasoning selectors: session model, reasoning level (when present), subagent models. New subagentModelsControl slot in session-ui PromptInput; app-side control mirrors the model button styling and opens DialogSubagentModels.

Subject: [PATCH 012/117] feat(hooks): add session.start, session.end, stop
 lifecycle hooks (#2)

Adds three optional lifecycle hooks to the plugin system, mirroring
Claude Code's PreToolUse/PostToolUse/SessionStart/SessionEnd/Stop
surface for the cases OpenCode was missing.

Events:
- session.start: fires when a session is created, before any tool
  calls. Plugin may tag the session via output.metadata (reserved
  keys blocked).
- stop: fires at end of every agent turn. If the plugin sets
  output.continue = true and reason === 'completed', the loop
  re-iterates with the same context. Honored only on 'completed' to
  prevent infinite loops on aborted or errored turns.
- session.end: fires before session deletion, hard-capped at 5s.
  output.cleanup = false defers forced cleanup within the ceiling.

Implementation:
- packages/plugin/src/index.ts: adds three optional fields to the
  Hooks interface (purely additive, no breaking change to existing
  plugins).
- packages/opencode/src/session/session.ts: emits session.start
  inside createNext; emits session.end inside remove with timeout
  and error isolation. Plugin.node is wrapped in a lazy Proxy to
  avoid a TDZ error from the session<->plugin circular import.
- packages/opencode/src/session/prompt.ts: emits stop inside the
  inner 'result === stop' branch where the runLoop is about to
  break. Honors output.continue by returning 'continue' instead of
  'break' so the while loop re-iterates.

Tests (6 new, all passing in 4.4s):
- packages/opencode/test/plugin/trigger-lifecycle.test.ts: 5 tests
  using a real plugin file loaded via opencode.json. Verifies that
  session.start, session.end, and stop receive the documented input
  shapes; that session.end output.cleanup and stop output.continue
  mutations propagate; and that stop output defaults to
  continue=false when the plugin does not touch it.
- packages/opencode/test/session/lifecycle-hooks.test.ts: 1 E2E test
  that creates a session via Session.Service.create and verifies
  the loaded plugin's session.start hook fires with the correct
  sessionID, cwd, and timestamp.

Docs:
- packages/docs/plugins.mdx: full reference for all three hooks
  (input/output tables, error-handling contract, end-to-end
  telemetry example). Added to docs.json navigation under a new
  'Plugins' group.

Error handling: every emit is wrapped in Effect.catch that logs and
continues; a throwing plugin never breaks session creation, deletion,
or the agent loop. The 5s session.end timeout is enforced via
Effect.timeout.

+title: "Lifecycle hooks"
+description: "React to session and turn boundaries from your plugin"
+---
+
+Plugins can subscribe to lifecycle events to react when a session starts, when
+the agent finishes a turn, and when a session is about to end. All three hooks
+are optional; declare only the ones you need.
+
+## `session.start`
+
+Fires once when a session is created, before any tool calls. Use this to set up
+per-session state in your plugin (background workers, telemetry handles, audit
+log entries).
+
+```ts
+import type { Hooks } from "@opencode-ai/plugin"
+
+const plugin: Hooks = {
+  "session.start": async (input, output) => {
+    console.log(`session ${input.sessionID} starting in ${input.cwd}`)
+    // Tag the session for downstream consumers
+    output.metadata.tenant = "acme"
+    output.metadata.tier = "pro"
+  },
+}
+
+export default async () => plugin
+```
+
+### Input
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `sessionID` | `string` | Unique session identifier |
+| `cwd` | `string` | Working directory of the session |
+| `agent` | `string` | Agent name (empty string if unset) |
+| `timestamp` | `number` | Unix epoch (ms) when the session was created |
+
+### Output
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `metadata` | `Record<string, unknown>` | Plugin tags merged into the session record. Reserved keys (`sessionID`, `cwd`, `agent`, `timestamp`) are rejected. |
+
+## `stop`
+
+Fires once at the end of an agent turn, after the LLM produces its final
+message (or the turn aborts/errors). The most common use is post-turn work
+(commit, summarize, notify) or requesting another turn.
+
+```ts
+import type { Hooks } from "@opencode-ai/plugin"
+
+const plugin: Hooks = {
+  stop: async (input, output) => {
+    if (input.reason === "completed") {
+      console.log(`turn complete in session ${input.sessionID}`)
+    }
+    // Re-run the loop with the same context (advanced)
+    output.continue = false
+  },
+}
+
+export default async () => plugin
+```
+
+### Input
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `sessionID` | `string` | Session the turn belongs to |
+| `agent` | `string` | Agent name that produced the turn |
+| `messageID` | `string` | ID of the final assistant message |
+| `reason` | `"completed" \| "aborted" \| "error"` | How the turn ended |
+
+### Output
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `continue` | `boolean` | If `true`, the loop re-iterates with the same context instead of returning. Honored only when `reason === "completed"`. Defaults to `false`. |
+
+<Warning>
+  Setting `output.continue = true` re-runs the same `lastUser` through the LLM
+  with no synthetic prompt. Use sparingly — the loop will not re-ask the user
+  for input. To break out of a continued loop, your plugin must not set
+  `output.continue = true` on a subsequent turn.
+</Warning>
+
+## `session.end`
+
+Fires once before a session is deleted, before the existing `dispose` lifecycle.
+Use this for cleanup (flush buffers, close connections, write final audit
+entries). The hook is hard-capped at 5 seconds; slow plugins are timed out, not
+allowed to block shutdown.
+
+```ts
+import type { Hooks } from "@opencode-ai/plugin"
+
+const plugin: Hooks = {
+  "session.end": async (input) => {
+    console.log(
+      `session ${input.sessionID} ended after ${input.duration_ms}ms (${input.reason})`,
+    )
+  },
+}
+
+export default async () => plugin
+```
+
+### Input
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `sessionID` | `string` | Session being deleted |
+| `duration_ms` | `number` | Wall-clock time since `session.start` |
+| `turn_count` | `number` | Number of agent turns completed in this session |
+| `reason` | `"user_exit" \| "error" \| "timeout"` | Why the session is ending |
+
+### Output
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `cleanup` | `boolean` | If `false`, the runtime defers forced cleanup for up to 5 seconds (hard ceiling). Defaults to `true`. |
+
+## Error handling
+
+A plugin that throws inside any lifecycle hook is logged via `Effect.logError`
+and the session/loop continues normally. Lifecycle hooks are **observers, not
+gatekeepers** — they cannot block a session from starting, ending, or stopping
+a turn. If you need to enforce a policy, use the permission system instead.
+
+## Example: a telemetry plugin
+
+```ts
+import type { Hooks } from "@opencode-ai/plugin"
+
+const startTimes = new Map<string, number>()
+
+const hooks: Hooks = {
+  "session.start": async (input) => {
+    startTimes.set(input.sessionID, input.timestamp)
+    fetch("https://telemetry.example.com/sessions", {
+      method: "POST",
+      body: JSON.stringify({ id: input.sessionID, cwd: input.cwd, agent: input.agent }),
+    })
+  },
+  "session.end": async (input) => {
+    const start = startTimes.get(input.sessionID) ?? input.timestamp
+    fetch("https://telemetry.example.com/sessions/end", {
+      method: "POST",
+      body: JSON.stringify({
+        id: input.sessionID,
+        duration_ms: input.duration_ms,
+        reason: input.reason,
+        start,
+      }),
+    })
+    startTimes.delete(input.sessionID)
+  },
+  stop: async (input) => {
+    if (input.reason !== "completed") return
+    fetch("https://telemetry.example.com/turns", {
+      method: "POST",
+      body: JSON.stringify({ sessionID: input.sessionID, messageID: input.messageID }),
+    })
+  },
+}
+
+export default async () => hooks
+```

Subject: [PATCH 015/117] feat(providers): multiple labeled API keys per
 provider (#3)

* feat(core): multiple labeled API keys per provider

* feat(providers): resolve labeled API keys at runtime in v1

* fix(providers): address cold review findings

- resolve getProvider through ensureProvider so keys added post-boot
  don't race a missing provider entry (crash on first request)
- re-read credential state in ensureProvider to pick up remove/update
- fail loudly in v2 runner when a virtual credential is missing instead
  of silently routing to a different active key
- respect provider.disabled for virtual provider availability
- redact API keys from the public provider list response
- honor disabled/enabled provider sets in the post-boot catalog fallback
- route vars/model loaders to the base provider for virtual ids

* fix(app): persist labeled keys via v2 credential route

connect.key was overridden to write legacy auth.json, dropping the label
and never creating a credential row. Try the v2 integration connect.key
(which stores a labeled credential) first, falling back to the legacy
auth write only when the server lacks the v2 route.

* test(app): cover v2-first connect.key with legacy fallback

* fix(providers): address second cold review round

- server-compat connect.key falls back to legacy auth only on missing-route
  (404/405), re-throwing real credential failures (400/401/500) instead of
  silently writing legacy auth on top of a broken key
- getProvider now fails typed with NoProvidersError; update the existing
  provider test that asserted the old undefined-return, and hoist the
  getProvider error channel in the Service interface so consumers handle
  the typed failure
- fix parseVirtualID usage in vars/model loader lookup (baseID, not base)
  and type the credential id lookup

Subject: [PATCH 016/117] feat(app): pre-first-message subagent model scoping

Composer button and dialog now work on drafts: toggles accumulate in a draft-scoped pending set, flushed into session permission rules right after session creation and before the first prompt is sent (sequential, no race). Button visible in both V2 and legacy composers; sessionID threaded via props.

Subject: [PATCH 017/117] feat(opencode): session subagent-model allowlist in
 task tool description

describeTask appends the session's allowed provider/model patterns (same last-match-wins semantics as enforcement) so the model sees exactly what it may pass as task model, plus a pointer to the parameter. No session rules means no section (unchanged behavior).

Subject: [PATCH 018/117] fix(app): tasks dedup by child session and model read
 from promise shape
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Child cards are now keyed exclusively by child session id (children() authoritative, task tool parts enrich or fall back to orphans) — fixes duplicate agent cards. childStats reads the promise-client message shape (type: assistant, model: {id, providerID}) alongside the legacy flat fields — restores per-card model + tokens. Headlines strip the ' (@agent subagent)' suffix.

From: Gustavo Schneiter <gustavomalleths@gmail.com>

Subject: [PATCH 020/117] perf(core): stop writing duplicate snapshot events in
 local mode (#7)

* refactor(opencode): lazy-load CLI commands to cut startup cost

The entrypoint statically imported every command module (server, session,
sdk, config schemas) at process start, costing tens of seconds and ~200MB
RSS even for fast paths like --version. Register commands through a
delegating module that only loads the real implementation when yargs
parses an invocation that exercises it.

Measured: --version instructions 10.4B -> 5.6B (-46%), peak RSS
224MB -> 132MB (-41%), user CPU 3.4s -> 1.9s (-44%).

Also decouple UI.cancelled-error from the effect import so the ui module
loads without pulling in the full effect runtime.

* perf(core): skip durable event log for message/part updates in local mode

updateMessage/updatePart published full snapshot events to the durable
event table on every change, duplicating the complete payload per update.
A single 23MB message re-rendered 90x wrote ~2GB of redundant JSON to the
event log (the user's opencode.db grew to 7GB, 6.4GB of it the event
table). The only consumer of these durable rows is the experimental
workspaces sync (off by default); the local UI/SSE/projection read the
projected message/part tables.

Add PublishOptions.persist (default true = unchanged). updateMessage/
updatePart pass persist: experimentalWorkspaces so local installs stop
appending to the event log while still projecting and notifying. With
workspaces enabled the behavior is byte-identical to before. The bridge
only emits sync envelopes for events carrying a durable marker, so local
events are never observed by cross-instance sync.

Measured: write-path E2E (90x growing part up to 24MB) 10.2s -> 5.5s
(-46%); publish micro-bench -92%; durable bytes per turn 100% eliminated.

Add db compact command as an optional one-shot tool to reclaim rows
already written (guarded against experimentalWorkspaces, which requires
contiguous seq for sync replay).

* refactor(opencode): type lazyCommand without any

* test(core): drop timing-based persist benchmark

The publish timing bench was flaky under machine load and duplicated the
behavioral coverage already provided by event-persist-gate. The measured
speedup (write-path E2E -46%, publish micro-bench -92%) is captured in the
perf commit message instead of as a timing assertion.

* docs(core): explain persist:false seq placeholder and commit hook contract

Reviewers need the invariant spelled out: the local-only publish path
supplies an inert seq placeholder to projectors (none read it) and skips
commit hooks by design (no caller combines them). Adds the rationale for
gating message/part persistence on experimentalWorkspaces in session.ts.

* feat(opencode): add native HuGR composer tools

Subject: [PATCH 022/117] feat(opencode): CLI benchmark harness for the read
 tool

Adds 'opencode debug read --params <json>' to invoke the legacy read tool directly without an LLM. Emits a machine-readable envelope: params, latency ms, title, metadata (incl. telemetry source/size/lines_read/saved) and output. Failures come back as ok:false with the error. Runs under Effect.scoped so LSP deps resolve.

bench-read.sh runs N invocations of 'opencode debug read' across whole/symbol/tail modes against a target file and emits CSV (mode,runs,avg,p50,p95,size,lines_read,saved,source). Supports BENCH_SYMBOL override and --json for full envelopes. Bash-only (no %f printf; stats via python).

Subject: [PATCH 024/117] perf(read): memoized whole-file scan, tail via cache;
 hardcore benchmark harness

findSymbolByIndent and tail line-count now share a path+mtime+size memo scan cache, fixing two defects the benchmark exposed: (1) symbols past line 2000 fell back to an unbounded scan every call even warm; (2) tail's negative-offset line count re-read the full file uncached (~1s on 15k-line files). Scan cache is bounded at 200k lines. debug read now accepts a params ARRAY (warm in-process runs), --meta-only (envelope without output payload for benchmark-safe huge reads), and emits envelopes with write-flush. Ship bench-corpus.sh (3 sizes x 2 densities), bench-hardcore.sh (cold+warm matrix over whole/symbol/tail/depth), bench-report.py (latency, output-bytes deltas, resolution source, slice economics).

Subject: [PATCH 025/117] feat(read): auto-degrade on unresolvable symbol +
 token-gate PARTIAL view
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two hardening deltas from the cross-market comparison (Claude/Codex/Grok), benchmark-validated against the corpus:

1. Unresolvable symbol now DEGRADES to a normal file read with a <system-note> instead of failing — the model never pays a second round-trip on a probe name. Symbol resolution contract unchanged on the happy path (LSP → indentation → render); failure path switched from hard error to graceful continuation.

2. Token budget (25k est, ~2 bytes/token conservative bound) cuts dense content earlier than the 50KB byte cap with a 'PARTIAL view' footer + next offset, so token-dense reads never dump a context bomb (Grok parity). Code ASCII fires the gate co-incident with the byte cap; tests updated: symbol-not-found now asserts degradation; new PARTIAL-view truncation test.

Benchmark (v2, same corpus): no regression — symbol slice economics identical (15,005/15,009 lines saved large-dense; -97..-99% output), resolution accuracy unchanged, cold→warm unchanged.

+# read tool — benchmark final (state: PR #6 @ d1ac7442)
+
+Corpus: 6 files (384 L → 15 009 L), 2 densities. Modes: whole/symbol/tail/depth. Warm = 9 in-process reads (hot cache, session-high). p50 latency; bytes = proxy for tokens.
+
+## Latency — warm p50 ms
+| file | whole | symbol | tail | depth |
+|---|---|---|---|---|
+| large-dense (15k L) | 90 | 274 | 633 | 584 |
+| large-sparse (15k L) | 341 | 968 | 669 | 865 |
+| med-dense (3.7k L) | 145 | 276 | 227 | 235 |
+| med-sparse (3.8k L) | 65 | 89 | 116 | 193 |
+| small-dense (384 L) | 32 | 24 | 18 | 12 |
+| small-sparse (456 L) | 10 | 13 | 14 | 12 |
+
+Noise from 24 x 150 MB binary spawn; p50 chosen for robustness. symbol/tail CL slower only on 15k-L files (unbounded indent scan dominates), comparable-or-faster on smaller.
+
+## Token economics — output bytes, warm avg (the metric that matters)
+| file | whole | symbol | Δ | tail | Δ |
+|---|---|---|---|---|---|
+| large-dense | 58,470 | 343 | **-99%** | 279 | **-100%** |
+| large-sparse | 47,928 | 48,081 | ≈ | 435 | **-99%** |
+| med-dense | 58,467 | 335 | **-99%** | 271 | **-100%** |
+| med-sparse | 57,888 | 18,463 | -68% | 417 | **-99%** |
+| small-dense | 10,799 | 331 | **-97%** | 267 | **-98%** |
+| small-sparse | 20,378 | 3,515 | -83% | 403 | **-98%** |
+
+## Cold → warm (symbol, p50)
+| file | cold | warm | Δ |
+|---|---|---|---|
+| small-dense | 110 | 24 | **4.6x** |
+| med-sparse | 439 | 89 | **4.9x** |
+| large-dense | 808 | 274 | 2.9x |
+
+Hot cache makes the cheapest real-world path ~3-5x cheaper than a cold start.
+
+## Resolution + slice economics (warm, symbol)
+- All 6 files resolve via indentation heuristic (0 LSP in headless bench env) — accuracy 100% on target symbols.
+- large-sparse: targetFunc is 3,003 lines; tool delivers 2,000-line cap page + `Use offset=` → model pages. (Large-symbol paging, not a bug: MAX_LINE cap.)
+- slice economics:
+  - large-dense: read 4 of 15,009 lines → saved **15,005**
+  - small-dense: 4 of 384 → saved 380
+  - large-sparse: 2,000 of 15,006 → saved 13,006 (delivered under 25k token gate)
+
+## Conclusion
+- Token gate + PARTIAL view + degrade verified post-change (43/43 tests).
+- Dense files (real functions): **-97%..-99% output** vs whole read.
+- Sparse giant symbol: still **-68%..-83%** even when the symbol itself is huge, or `≈` when target is almost whole file.
+- Latency parity on small/med; only 15k-L unbounded scans are slower (indent fallback).

Subject: [PATCH 027/117] feat(read): search param auto-resolves symbol range +
 sparse numbering + metaprompt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends the read tool with the async-resolve capabilities recommended after the cross-market comparison + RL adoption research:

- search='<fragment>' — find a symbol by name fragment and read ONLY that range, auto-resolving via LSP → indentation heuristic → degrade, so the model can request a precise slice without knowing the exact symbol name and without paying a second round-trip on a miss. Shares the resolveRange path with symbol; source reported.
- expand: sparse=true numbering (anchor 1 + every 10th, Grok-style) opt-in to cut numbering tokens on huge reads; default unchanged.
- read.txt metaprompt: instructs models to prefer symbol/search over whole-file reads when a name/fragment is known, since the tool degrades safely on a miss — nudging RILI(RL) adoption without changing the contract or adding decision friction.

Tests 45/45 (new: search-by-fragment, sparse anchors). Benchmark v3: search delivers -99% output on dense files (58,470 → 469 chars), consistent with symbol; no regression on whole/tail.

 - The offset parameter is the line number to start from (1-indexed).
 - To read later sections, call this tool again with a larger offset.
 - Use the grep tool to find specific content in large files or files with long lines.
+- Prefer reading a SYMBOL over the whole file when you know (or can guess) the name of the function/class/const you need: pass symbol="<name>" to read only that symbol's range, which returns far fewer tokens and less context. If you only know a fragment of the name, use search="<fragment>".
+- If a symbol name is not found, this tool automatically degrades to a normal file read, so preferring symbol/search is always safe.
 - If you are unsure of the correct file path, use the glob tool to look up filenames by glob pattern.
 - Contents are returned with each line prefixed by its line number as `<line>: <content>`. For example, if a file has contents "foo\n", you will receive "1: foo\n". For directories, entries are returned one per line (without line numbers) with a trailing `/` for subdirectories.
 - Any line longer than 2000 characters is truncated.

-# read tool — benchmark final (state: PR #6 @ d1ac7442)
+# Read Benchmark
 
-Corpus: 6 files (384 L → 15 009 L), 2 densities. Modes: whole/symbol/tail/depth. Warm = 9 in-process reads (hot cache, session-high). p50 latency; bytes = proxy for tokens.
+Correctness-first harness for `filePath`, `offset`, `limit`.
 
-## Latency — warm p50 ms
-| file | whole | symbol | tail | depth |
-|---|---|---|---|---|
-| large-dense (15k L) | 90 | 274 | 633 | 584 |
-| large-sparse (15k L) | 341 | 968 | 669 | 865 |
-| med-dense (3.7k L) | 145 | 276 | 227 | 235 |
-| med-sparse (3.8k L) | 65 | 89 | 116 | 193 |
-| small-dense (384 L) | 32 | 24 | 18 | 12 |
-| small-sparse (456 L) | 10 | 13 | 14 | 12 |
+## Run
 
-Noise from 24 x 150 MB binary spawn; p50 chosen for robustness. symbol/tail CL slower only on 15k-L files (unbounded indent scan dominates), comparable-or-faster on smaller.
+```bash
+./bench-corpus.sh /tmp/bench-corpus
+./bench-hardcore.sh <opencode-binary> /tmp/bench-corpus 5 /tmp/bench-result
+```
 
-## Token economics — output bytes, warm avg (the metric that matters)
-| file | whole | symbol | Δ | tail | Δ |
-|---|---|---|---|---|---|
-| large-dense | 58,470 | 343 | **-99%** | 279 | **-100%** |
-| large-sparse | 47,928 | 48,081 | ≈ | 435 | **-99%** |
-| med-dense | 58,467 | 335 | **-99%** | 271 | **-100%** |
-| med-sparse | 57,888 | 18,463 | -68% | 417 | **-99%** |
-| small-dense | 10,799 | 331 | **-97%** | 267 | **-98%** |
-| small-sparse | 20,378 | 3,515 | -83% | 403 | **-98%** |
+Harness overwrites deterministic corpus files and validates SHA-256 manifest. Each serial run validates JSON envelope, numbered range, exact returned content against source oracle. Missing corpus, malformed/no envelope, malformed JSON, invalid output, oracle mismatch, unsuccessful process, no rows, missing expected cells, wrong row count fail run.
 
-## Cold → warm (symbol, p50)
-| file | cold | warm | Δ |
-|---|---|---|---|
-| small-dense | 110 | 24 | **4.6x** |
-| med-sparse | 439 | 89 | **4.9x** |
-| large-dense | 808 | 274 | 2.9x |
+Modes: default, explicit slice, tail, oversized default, oversized explicit range. Corpus: LF, CRLF, Unicode/emoji, long-line, dense-large, sparse-large.
 
-Hot cache makes the cheapest real-world path ~3-5x cheaper than a cold start.
+`output_chars` means JavaScript string character count, not bytes or tokens. `elapsed_ms` includes CLI startup. p50/p95 only shown where sample size >=2.
 
-## Resolution + slice economics (warm, symbol)
-- All 6 files resolve via indentation heuristic (0 LSP in headless bench env) — accuracy 100% on target symbols.
-- large-sparse: targetFunc is 3,003 lines; tool delivers 2,000-line cap page + `Use offset=` → model pages. (Large-symbol paging, not a bug: MAX_LINE cap.)
-- slice economics:
-  - large-dense: read 4 of 15,009 lines → saved **15,005**
-  - small-dense: 4 of 384 → saved 380
-  - large-sparse: 2,000 of 15,006 → saved 13,006 (delivered under 25k token gate)
-
-## Conclusion
-- Token gate + PARTIAL view + degrade verified post-change (43/43 tests).
-- Dense files (real functions): **-97%..-99% output** vs whole read.
-- Sparse giant symbol: still **-68%..-83%** even when the symbol itself is huge, or `≈` when target is almost whole file.
-- Latency parity on small/med; only 15k-L unbounded scans are slower (indent fallback).
-
-Raw: /tmp/bench-result-final/raw.csv · results.json cols: ms p50/avg, ochars, lr, size, saved, src_lsp/indent.
+No symbol, search, depth, sparse, token, byte, or accuracy claim. No LSP oracle. Debug params JSON-only. Debug runner removes throwaway session in finalizer.

-# Example:
-#   ./bench-read.sh packages/opencode/dist/opencode-darwin-x64/bin/opencode /tmp/sample.js 5

-# Modes tested (unless --single):
-#   - whole:  read with no symbol/tail (baseline)
-#   - symbol: read with symbol=first_fun (first function/class in file)
-#   - tail:   read with offset=-5

+Harness overwrites deterministic corpus files and validates SHA-256 manifest. Each serial run validates JSON envelope and expected outcome. Success validates numbered range plus exact returned content against source oracle. Oversized explicit range expects `ok:false` with `Offset 3001 is out of range`; it must not contain output. Missing corpus, malformed/no envelope, malformed JSON, invalid output, oracle mismatch, wrong outcome, unsuccessful process, no rows, missing expected cells, wrong row count fail run.
 
 Modes: default, explicit slice, tail, oversized default, oversized explicit range. Corpus: LF, CRLF, Unicode/emoji, long-line, dense-large, sparse-large.
 
 `output_chars` means JavaScript string character count, not bytes or tokens. `elapsed_ms` includes CLI startup. p50/p95 only shown where sample size >=2.
 
-No symbol, search, depth, sparse, token, byte, or accuracy claim. No LSP oracle. Debug params JSON-only. Debug runner removes throwaway session in finalizer.
+Run self-tests with `BENCH_SELF_TEST=1 ./bench-hardcore.sh "$(command -v true)"`. They prove malformed envelope, zero rows, oracle mismatch, unexpected success/error outcomes fail closed. No symbol, search, depth, sparse, token, byte, or accuracy claim. No LSP oracle. Debug params JSON-only. Debug runner removes throwaway session in finalizer. Report records expected/observed outcomes, test count/cell completeness, runtime platform/Python/binary, and states missing CPU/memory/disk/load controls.

+Harness overwrites deterministic corpus files and validates SHA-256 manifest. Each serial run validates JSON envelope and expected outcome. Success validates numbered range plus exact returned content against source oracle. Oversized explicit range is valid source range `offset=1, limit=1000` over dense post-truncation lines; it expects `ok:false` with `Requested range exceeds 50 KB output limit` and no output. Missing corpus, malformed/no envelope, malformed JSON, invalid output, oracle mismatch, wrong outcome, unsuccessful process, no rows, missing expected cells, wrong row count fail run.
 
 Modes: default, explicit slice, tail, oversized default, oversized explicit range. Corpus: LF, CRLF, Unicode/emoji, long-line, dense-large, sparse-large.
 
 `output_chars` means JavaScript string character count, not bytes or tokens. `elapsed_ms` includes CLI startup. p50/p95 only shown where sample size >=2.

-Read a file or directory from the local filesystem. If the path does not exist, an error is returned.
+Read a file or directory from local filesystem. Missing paths return an error.
 
-Usage:
-- The filePath parameter should be an absolute path.
-- By default, this tool returns up to 2000 lines from the start of the file.
-- The offset parameter is the line number to start from (1-indexed).
-- To read later sections, call this tool again with a larger offset.
-- Use the grep tool to find specific content in large files or files with long lines.
-- Prefer reading a SYMBOL over the whole file when you know (or can guess) the name of the function/class/const you need: pass symbol="<name>" to read only that symbol's range, which returns far fewer tokens and less context. If you only know a fragment of the name, use search="<fragment>".
-- If a symbol name is not found, this tool automatically degrades to a normal file read, so preferring symbol/search is always safe.
-- If you are unsure of the correct file path, use the glob tool to look up filenames by glob pattern.
-- Contents are returned with each line prefixed by its line number as `<line>: <content>`. For example, if a file has contents "foo\n", you will receive "1: foo\n". For directories, entries are returned one per line (without line numbers) with a trailing `/` for subdirectories.
-- Any line longer than 2000 characters is truncated.
-- Call this tool in parallel when you know there are multiple files you want to read.
-- Avoid tiny repeated slices (30 line chunks). If you need more context, read a larger window.
-- This tool can read image files and PDFs and return them as file attachments.
+- `filePath` is absolute path.
+- Default read returns up to 2000 lines from start.
+- Positive `offset` is 1-indexed start line. Negative `offset` reads from end: `-3` starts last 3 lines.
+- `limit` is positive maximum line count.
+- Use `glob` to locate unknown paths. Use `grep` for large-file search.
+- Lines have `<line>: <content>` prefixes. Directory entries have trailing `/`.
+- Lines longer than 2000 characters truncate.
+- Images and PDFs return file attachments.

+## Performance
+
+`bench-performance.sh` is separate from correctness corpus and harness. It creates deterministic 1MiB and 100MiB text fixtures only under `--corpus` (default `/tmp/opencode-read-performance-corpus`); `--large` adds 1GiB. It never writes correctness corpus.
+
+```bash
+./bench-performance.sh <compiled-opencode-binary> --corpus /tmp/opencode-read-performance-corpus --out /tmp/opencode-read-performance-result
+BENCH_PERFORMANCE_SELF_TEST=1 ./bench-performance.sh
+```
+
+Rows are serial `default`, `explicit_small_slice`, and `tail_offset_minus_5` calls. JSON/Markdown record `process_elapsed_ms` (startup included), envelope `operation_ms`, peak RSS bytes, OS/CPU/runtime/binary identity, and fixture hashes. macOS parses `/usr/bin/time -l`; Linux parses `/usr/bin/time -v` kbytes into bytes; other OSes fail `unsupported-platform`. 1GiB is opt-in: require at least 1GiB free disk plus overhead; do not use during active workload.

 `--runs N` defaults to 3 and requires positive integer. Rows are serial `default`, `explicit_small_slice`, and `tail_offset_minus_5` calls. JSON/Markdown record raw per-run rows plus min/avg/p50/p95 for `process_elapsed_ms` (startup included), envelope `operation_ms`, and peak RSS bytes. With one run, p50/p95 are `n/a`. Missing/duplicate cell rows, invalid metrics, or missing modes fail before report. macOS parses `/usr/bin/time -l`; Linux parses `/usr/bin/time -v` kbytes into bytes; other OSes fail `unsupported-platform`. 1GiB is opt-in: require at least 1GiB free disk plus overhead; do not use during active workload.
+
+Each validated row is appended then flushed and fsynced to `<out>/raw.jsonl`; progress prints per row. New runs deliberately truncate that file first. Interrupted runs retain raw evidence but do not produce a success report. Recover only complete evidence with `./bench-performance.sh --report-only --corpus DIR --out DIR --runs N --sizes 1MiB,100MiB`; missing/duplicate/malformed rows fail without changing `raw.jsonl`. `--sizes` defaults to `1MiB,100MiB`; supports each size once. `1GiB` requires both `--large` and explicit `--sizes ...1GiB`.

+## Model Read Agent A/B
+
+`bench-read-agent.sh` compares two compiled binaries through real `opencode run --format json` sessions. Model IDs must be explicit `provider/model` values. It never embeds credentials; normal provider configuration supplies them.
+
+```bash
+./bench-read-agent.sh --baseline /path/to/baseline --candidate /path/to/candidate --models openai/gpt-5.6-luna --runs 1 --out /tmp/read-agent-ab
+./bench-read-agent.sh --self-test
+```
+
+Corpus is deterministic and written only to `<out>/corpus`: 20,000-decoy tail marker, middle marker, and long-line marker. `manifest.json` stores each fixture SHA-256 plus exact task answer. Every binary/model/task/run saves raw JSON events under `<out>/raw-events`; `trials.jsonl`, `results.json`, and `report.md` contain parsed evidence and paired rows.
+
+Parser accepts current CLI event schema only (`tool_use`, `text`, `step_start`, `step_finish`, `error`). Malformed or unsupported streams, process/model errors, missing final response, no `read` call, missing exact marker, duplicate tool result, and incomplete pairs fail closed. Tool calls include inputs and actual output/error results. Retry telemetry is `N/A` because current CLI JSON emits no retry event; token input/output and cost are `N/A` unless `step_finish` exposes them. `N/A` never means zero.
+
 Run self-tests with `BENCH_SELF_TEST=1 ./bench-hardcore.sh`. They prove malformed envelope, zero rows, oracle mismatch, exact expected-error fragment mismatch, unexpected success/error outcomes fail closed. Out-of-range offsets are outside this benchmark scope. No symbol, search, depth, sparse, token, byte, or accuracy claim. No LSP oracle. Debug params JSON-only. Debug runner removes throwaway session in finalizer. Report records expected/observed outcomes, test count/cell completeness, runtime platform/Python/binary, and states missing CPU/memory/disk/load controls.
 ## Performance

-Corpus is deterministic and written only to `<out>/corpus`: 20,000-decoy tail marker, middle marker, and long-line marker. `manifest.json` stores each fixture SHA-256 plus exact task answer. Every binary/model/task/run saves raw JSON events under `<out>/raw-events`; `trials.jsonl`, `results.json`, and `report.md` contain parsed evidence and paired rows.
+Corpus is deterministic and written only to `<out>/corpus`: 20,000-decoy tail marker, middle marker, and long-line marker. New output roots must be empty. New runs write immutable `plan.json` with binary paths/SHA-256/version, models, task answers, corpus hashes, runs, and timeout. `--resume` requires exact plan match, validates persisted rows, skips completed keys, and never overwrites raw events. Every completed binary/model/task/run appends one normalized row to `<out>/raw-results.jsonl`, flushes and fsyncs it, then prints progress. Every raw JSON event stream stays under `<out>/raw-events`.
 
-Parser accepts current CLI event schema only (`tool_use`, `text`, `step_start`, `step_finish`, `error`). Malformed or unsupported streams, process/model errors, missing final response, no `read` call, missing exact marker, duplicate tool result, and incomplete pairs fail closed. Tool calls include inputs and actual output/error results. Retry telemetry is `N/A` because current CLI JSON emits no retry event; token input/output and cost are `N/A` unless `step_finish` exposes them. `N/A` never means zero.
+Each model process has `--timeout-sec` limit, default 180 seconds. Timeout terminates process group, persists `timeout` outcome, then continues remaining cells. Exact marker remains only `success`; timeout and malformed/model outcomes fail closed. `--report-only` never calls models: it validates `plan.json`, corpus hashes, and all persisted rows, refusing malformed, duplicate, unexpected, or missing keys. Reports write only after complete evidence. Tool calls include inputs and actual output/error results. Retry telemetry is `N/A` because current CLI JSON emits no retry event; token input/output and cost are `N/A` unless `step_finish` exposes them. `N/A` never means zero.
 
 Run self-tests with `BENCH_SELF_TEST=1 ./bench-hardcore.sh`. They prove malformed envelope, zero rows, oracle mismatch, exact expected-error fragment mismatch, unexpected success/error outcomes fail closed. Out-of-range offsets are outside this benchmark scope. No symbol, search, depth, sparse, token, byte, or accuracy claim. No LSP oracle. Debug params JSON-only. Debug runner removes throwaway session in finalizer. Report records expected/observed outcomes, test count/cell completeness, runtime platform/Python/binary, and states missing CPU/memory/disk/load controls.

-Corpus is deterministic and written only to `<out>/corpus`: 20,000-decoy tail marker, middle marker, and long-line marker. New output roots must be empty. New runs write immutable `plan.json` with binary paths/SHA-256/version, models, task answers, corpus hashes, runs, and timeout. `--resume` requires exact plan match, validates persisted rows, skips completed keys, and never overwrites raw events. Every completed binary/model/task/run appends one normalized row to `<out>/raw-results.jsonl`, flushes and fsyncs it, then prints progress. Every raw JSON event stream stays under `<out>/raw-events`.
+Corpus is deterministic and written only to `<out>/corpus`: 20,000-decoy tail marker, middle marker, and long-line marker. Each isolated child uses `opencode run --auto`; auto approval is limited to generated corpus under output root. New output roots must be empty. New runs write immutable `plan.json` with binary paths/SHA-256/version, models, task answers, corpus hashes, runs, and timeout. `--resume` requires exact plan match, validates persisted rows, skips completed keys including `timeout`/`failed`, and never overwrites raw events. Use new output directory to retry completed timeout or failure cells. Every completed binary/model/task/run appends one normalized row to `<out>/raw-results.jsonl`, flushes and fsyncs it, then prints progress. Every raw JSON event stream stays under `<out>/raw-events`.
 
-Each model process has `--timeout-sec` limit, default 180 seconds. Timeout terminates process group, persists `timeout` outcome, then continues remaining cells. Exact marker remains only `success`; timeout and malformed/model outcomes fail closed. `--report-only` never calls models: it validates `plan.json`, corpus hashes, and all persisted rows, refusing malformed, duplicate, unexpected, or missing keys. Reports write only after complete evidence. Tool calls include inputs and actual output/error results. Retry telemetry is `N/A` because current CLI JSON emits no retry event; token input/output and cost are `N/A` unless `step_finish` exposes them. `N/A` never means zero.
+Each model process has `--timeout-sec` limit, default 180 seconds. Timeout terminates process group, persists `timeout` outcome, then continues remaining cells. Exact marker remains only `success`; timeout and malformed/model outcomes fail closed. Complete reports include per-cell `success`/`failed`/`timeout` counts, then evaluator exits nonzero when any trial failed closed. `--report-only` never calls models: it validates `plan.json`, corpus hashes, and all persisted rows, refusing malformed, duplicate, unexpected, or missing keys. Reports write only after complete evidence. Tool calls include inputs and actual output/error results. Retry telemetry is `N/A` because current CLI JSON emits no retry event; token input/output and cost are `N/A` unless `step_finish` exposes them. `N/A` never means zero.
 
 Run self-tests with `BENCH_SELF_TEST=1 ./bench-hardcore.sh`. They prove malformed envelope, zero rows, oracle mismatch, exact expected-error fragment mismatch, unexpected success/error outcomes fail closed. Out-of-range offsets are outside this benchmark scope. No symbol, search, depth, sparse, token, byte, or accuracy claim. No LSP oracle. Debug params JSON-only. Debug runner removes throwaway session in finalizer. Report records expected/observed outcomes, test count/cell completeness, runtime platform/Python/binary, and states missing CPU/memory/disk/load controls.

 Each model process has `--timeout-sec` limit, default 180 seconds. Timeout terminates process group, persists `timeout` outcome, then continues remaining cells. Exact marker remains only `success`; timeout and malformed/model outcomes fail closed. Complete reports include per-cell `success`/`failed`/`timeout` counts, then evaluator exits nonzero when any trial failed closed. `--report-only` never calls models: it validates `plan.json`, corpus hashes, and all persisted rows, refusing malformed, duplicate, unexpected, or missing keys. Reports write only after complete evidence. Tool calls include inputs and actual output/error results. Retry telemetry is `N/A` because current CLI JSON emits no retry event; token input/output and cost are `N/A` unless `step_finish` exposes them. `N/A` never means zero.

Subject: [PATCH 109/117] fix(pty): allow exited sessions via /api/pty/:id
 handler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove status===running guard in PtyHttpApi.get handler so exited
PTY sessions with their exit code are returned by the API.

This enables the PTY test to observe exit 4 → status: exited, exitCode: 4.

Subject: [PATCH 110/117] feat(desktop): app-dock RPC bridge + LLM tools

- Add app-dock-rpc.ts: bridge between sidecar and Electron main process for dock_* ops
- Add app-dock-browser.ts: injected scripts (snapshot, click, type, scroll, navigate, etc.)
- Add app-dock-api.ts: TypeScript interface for AppDock
- Add app-dock-tools.test.ts, app-dock-rpc.test.ts, app-dock-youtube.test.ts, app-dock-live.test.ts
- Extend app-dock.ts with execute(), scroll(), hover(), drag(), clickAt(), scrollTo(), storage(), evaluate(), network(), pdf(), list(), closeAll()
- Register RPC bridge in ipc.ts with profile resolver and new IPC handlers (app-dock-list, etc.)
- Update server.ts to accept sidecarPath and forward messages for RPC
- Add preload API: appDockList, tab-selected event
- Add opencode plugin: app-dock.ts with 16 dock_* tools (open, read, click, type, navigate, go, list, close, scroll, wait, screenshot, keyboard, evaluate, storage, network, activate)
- Add corpus docs: invariants, requirements, goldens, cards for app-dock

Subject: [PATCH 114/117] refactor(app-dock-rpc): class-based with reset, fix
 test cleanup

- Convert module singletons to AppDockRPC class with explicit init/reset
- Add resetAppDockRPC() export for test isolation
- Fix handleDockRPC to use proper promise chain (no async IIFE leak)
- Remove debug logging from app-dock-tools.test.ts
- Add 60s watchdog in child process to prevent hangs

Subject: [PATCH 115/117] fix(app-dock-rpc): test stability

- Add retry logic for read after reload to handle namespace stabilization
- Increase wait times after reload (500ms) and before fullscreen read (300ms)
- Window focus is now more reliably handled with registerAppDockWindow() call
