Steps use checkbox (`- [ ]`) syntax +> for tracking. + +**Goal:** Implement `POST /api/sessions/resolve` in the Rust server (`crates/freshell-server`) with full behavior parity to the Node implementation, declare the `sessionResolve` feature flag from the Rust server so the shared client shows the pinned sidebar Resume button on Rust builds, and prove it with cross-language parser fixtures plus the `resume-button` e2e spec green on BOTH Playwright projects. + +**Architecture:** A pure Rust port of `shared/resume-input-parser.ts` and the resolve matching core live in `crates/freshell-sessions` (`resume_input.rs`, `resume_resolve.rs`), pinned to the TS implementation by a shared JSON fixture table both test suites consume. A new focused axum module `crates/freshell-server/src/resolve.rs` owns the HTTP route (auth → zod-shaped validation → resolve core), reading the existing `SessionIndex` for evidence, the `SessionMetadataStore` for the `sessionType` overlay, and two exact-id fallbacks that already exist in Rust (claude transcript locator, opencode by-id sqlite — each extended minimally to also return cwd). + +**Tech Stack:** Rust (axum 0.8, tokio, serde/serde_json with `preserve_order`, `regex`, rusqlite), TypeScript (vitest, zod), Playwright. + +## Global Constraints + +- Work ONLY inside the worktree `/home/dan/code/freshell/.worktrees/rust-resolve-parity` on branch `feat/rust-resolve-parity`.

Allowed exceptions: refactoring `test/unit/shared/resume-input-parser.test.ts` to consume the shared fixture (behavior-identical), and a comment-only update in `server/platform-router.ts`. +- Wire parity is byte-shape parity: response JSON field ORDER matches the Node object literals (`serde_json` `preserve_order` is on workspace-wide; struct field order controls serde output order), optional match fields are OMITTED when absent (`skip_serializing_if`), and `hint` is `null` (never omitted) when absent. +- Constants copied from Node: result cap `RESOLVE_MATCH_CAP = 20`; request `input` length `1..=20000` counted in UTF-16 code units (zod `.min(1).max(20000)` semantics); validation failure is `400 { "error": "Invalid resolve request", "details": [...] }`; "not found" is NEVER 404 — it is `200 { "status": "ready", "matches": [] }`. +- Vitest: NEVER run raw `npx vitest`. Use `npm run test:vitest -- --config --run`. Before any broad run, check `npm run test:status`; set `FRESHELL_TEST_SUMMARY="SYNC-06 rust resolve parity"` on broad runs. +- Rust gates (CI-enforced): `cargo fmt --all -- --check` clean, `cargo clippy --workspace --all-targets -- -D warnings` clean. `cargo test --workspace` requires `node_modules` present (`test -d node_modules || npm ci --no-audit --no-fund`). +- Process safety: never use broad kill patterns (`pkill -f node`, `pkill -f vite`, …). The live self-hosted Rust server on port 3002 must NEVER be restarted (building is fine).

Rust port of `shared/resume-input-parser.ts` — a pure, dependency-free +//! parser that extracts candidate session ids and an advisory provider hint +//! from arbitrary pasted text. Hints only assist the UI — session-store +//! evidence decides the provider. +//! +//! PARITY-PINNED: both this port and the TS original are driven by the shared +//! fixture `test/fixtures/resume-input/parser-cases.json` +//! (`tests/resume_input_parser_parity.rs` here, +//! `test/unit/shared/resume-input-parser.test.ts` there). Behavior changes go +//! through the fixture first. +//! +//! Port notes (things that look odd but are load-bearing): +//! - `(?-u:\b)` everywhere a JS `\b` appears: JS word boundaries are ASCII +//! (`[A-Za-z0-9_]`); Rust's default `\b` is Unicode-aware and would diverge +//! on inputs like `é417e8345`. +//! - The ANSI CSI strip replaces each escape with ONE space (length-changing); +//! hint derivation reads that `sanitized` text, so earliest-match indices +//! shift with it. Do not "fix" this to a length-preserving mask. +//! - Extraction masks each match with `' '.repeat(len)` (length-preserving) +//! so UUID hex groups never re-match as hex prefixes. All matched chars are +//! ASCII, so byte length == char length. +//! - Hex tokens sort by length DESC with a STABLE sort (JS `Array.sort` is +//! stable): equal-length tokens keep extraction (text) order. + +use std::collections::HashSet; +use std::sync::LazyLock; + +use regex::Regex; + +#[derive(Debug, Clone, Copy, PartialEq, Eq, serde::Serialize, serde::Deserialize)] +pub enum ResumeCandidateKind { + #[serde(rename = "prefixed-id")] + PrefixedId, + #[serde(rename = "uuid")] + Uuid, + #[serde(rename = "hex-prefix")] + HexPrefix, +} + +#[derive(Debug, Clone, PartialEq, Eq, serde::Serialize)] +pub struct ResumeCandidate { + pub token: String, + pub kind: ResumeCandidateKind, +} + +#[derive(Debug, Clone, Copy, PartialEq, Eq, serde::Serialize)] +#[serde(rename_all = "lowercase")] +pub enum ResumeHintProvider { + Claude, + Codex, + Opencode, + Amplifier, +} + +#[derive(Debug, Clone, Copy, PartialEq, Eq, serde::Serialize)] +pub enum ResumeHintSource { + #[serde(rename = "command")] + Command, + #[serde(rename = "word")] + Word, + #[serde(rename = "id-shape")] + IdShape, +} + +#[derive(Debug, Clone, PartialEq, Eq, serde::Serialize)] +pub struct ResumeHint { + pub provider: ResumeHintProvider, + pub source: ResumeHintSource, +} + +#[derive(Debug, Clone, PartialEq, Eq)] +pub struct ResumeInputParse { + /// Candidate tokens in resolution-priority order. + pub candidates: Vec, + pub hint: Option, +} + +static ANSI_ESCAPE_RE: LazyLock = + LazyLock::new(|| Regex::new(r"\x1b\[[0-9;?]*[0-9A-Za-z]").expect("static regex")); +static UUID_RE: LazyLock = LazyLock::new(|| { + Regex::new(r"[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}") + .expect("static regex") +}); +// ses_ + 26 base62 is the first-class shape; the generic form also accepts +// other known xxx_-prefixed id families. +static PREFIXED_ID_RE: LazyLock = + LazyLock::new(|| Regex::new(r"(?-u:\b)[a-z]{2,10}_[0-9A-Za-z]{8,40}(?-u:\b)").expect("static regex")); +// >=8 hex chars, <=32; must contain a digit (filters decade/facade/deadbeef). +static HEX_PREFIX_RE: LazyLock = + LazyLock::new(|| Regex::new(r"(?-u:\b)[0-9a-fA-F]{8,32}(?-u:\b)").expect("static regex")); + +static COMMAND_HINTS: LazyLock> = LazyLock::new(|| { + vec![ + ( + Regex::new(r"(?i)(?-u:\b)claude\s+(?:--resume|-r)(?-u:\b)").expect("static regex"), + ResumeHintProvider::Claude, + ), + ( + Regex::new(r"(?i)(?-u:\b)codex\s+resume(?-u:\b)").expect("static regex"), + ResumeHintProvider::Codex, + ), + ( + Regex::new(r"(?i)(?-u:\b)opencode\s+--session(?-u:\b)").expect("static regex"), + ResumeHintProvider::Opencode, + ), + ( + Regex::new(r"(?i)(?-u:\b)amplifier\s+(?:--resume|resume)(?-u:\b)").expect("static regex"), + ResumeHintProvider::Amplifier, + ), + ] +}); + +static WORD_HINTS: LazyLock> = LazyLock::new(|| { + vec![ + ( + Regex::new(r"(?i)(?-u:\b)claude(?-u:\b)").expect("static regex"), + ResumeHintProvider::Claude, + ), + ( + Regex::new(r"(?i)(?-u:\b)codex(?-u:\b)").expect("static regex"), + ResumeHintProvider::Codex, + ), + ( + Regex::new(r"(?i)(?-u:\b)opencode(?-u:\b)").expect("static regex"), + ResumeHintProvider::Opencode, + ), + ( + Regex::new(r"(?i)(?-u:\b)amplifier(?-u:\b)").expect("static regex"), + ResumeHintProvider::Amplifier, + ), + ] +}); + +/// `extractAndMask`: push every match, replace it with a same-length run of +/// spaces so later passes cannot re-match inside it. +fn extract_and_mask(text: &str, re: &Regex, out: &mut Vec) -> String { + re.replace_all(text, |caps: ®ex::Captures<'_>| { + let m = caps.get(0).expect("group 0 always present").as_str(); + out.push(m.to_string()); + " ".repeat(m.len()) + }) + .into_owned() +} + +/// `earliestHint`: run every regex, keep the provider with the smallest match +/// start.

Spec coverage.** R1 endpoint parity → Task 6 (same path, same auth helper as all Rust API routes, zod-shaped strict validation with the exact 400 body, always-200 semantics). R2 parser parity + shared fixtures → Tasks 1–2 (one committed JSON table, both suites consume it). R3 matching parity (four providers, exact+prefix, most-recent-first, cap 20, matchKind) → Task 5 (+ HTTP-level pins in Task 6). R4 fallback parity → Tasks 3–4 reuse/extend the existing Rust machinery (opencode by-id sqlite gains a directory-returning sibling; the existing claude `locate_transcript` gains its already-written cwd companion via export) — nothing was found impractical, so no recorded deviation is needed. R5 metadata parity → Task 5 `to_match` + the sessionType overlay from the metadata store (Task 6 Step 1 un-gates the read; Node's overlay source is the same store, and absence is the normal case on both servers — the client falls back to `sessionType ?? provider`). R6 warming parity → Task 5/6 (peek-gated; hint still populated; `session_index: None` also warms, documented). R7 feature flag, ungated → Task 7. R8 checklist update with PW-TAURI-WIN out-of-scope note → Task 9. Verification section: Rust tests mirroring the Node suite (Task 5 + Task 6 tests), clippy/fmt (Tasks 2–9), cross-language fixtures (Tasks 1–2), e2e on both projects with guard removal + MATRIX_SPECS registration (Task 8), client suite untouched (comment-only TS changes; typecheck + the two vitest files re-run in Task 9). + +**1b. No silent deferrals.** Every requirement lands as production behavior proven by an observable outcome: the e2e paste-then-Enter test spawns a REAL CLI with `resume ` argv against the REAL Rust server binary (no stub); fallback closures in production wiring call the real sqlite/filesystem code (test doubles appear only inside unit tests, with the production path covered by Task 3/4's direct tests + Task 8's e2e). The single intentional error-path divergence (Rust answers ready-empty where Express would 500 on a thrown dependency) is recorded in code comments (Task 5/6) and follows the Rust port's existing never-5xx convention; it is unobservable by the client's happy path and untested on the Node side. + +**2. Placeholder scan.** No TBDs; every code step carries complete code; commands carry expected outputs. Two deliberate "verbatim-context" dependencies remain (main.rs line numbers drift; the implementer anchors on the quoted surrounding code, which is provided), and Task 9's evidence entry contains `//` placeholders that are explicitly instructed to be substituted with observed values — they cannot be known at plan time. + +**3. Type consistency.** `ResumeCandidateKind/{PrefixedId,Uuid,HexPrefix}`, `ResumeHint{provider,source}` (Task 2) are consumed with those exact names in Tasks 5–6. `OpencodeSessionDirectory{directory}` (Task 3) is the closure payload in Tasks 5–6. `ClaudeTranscriptHit{session_id,cwd}` (Task 5) is constructed in Task 6's wiring and tests. `ResolveDeps` field names/borrow shapes match between definition (Task 5) and use (Task 6: `as_deref()` against `Arc` matches the `&(dyn Fn ... + Send + Sync)` field type). `RESOLVE_MATCH_CAP` is defined once (Task 5) and asserted in tests. `SessionMetadataStore::new(dir)` appends `session-metadata.json` — Task 6's overlay test writes that exact filename into the dir it passes.

Two deliberate "verbatim-context" dependencies remain (main.rs line numbers drift; the implementer anchors on the quoted surrounding code, which is provided), and Task 9's evidence entry contains `//` placeholders that are explicitly instructed to be substituted with observed values — they cannot be known at plan time. **3. Type consistency.** `ResumeCandidateKind/{PrefixedId,Uuid,HexPrefix}`, `ResumeHint{provider,source}` (Task 2) are consumed with those exact names in Tasks 5–6. `OpencodeSessionDirectory{directory}` (Task 3) is the closure payload in Tasks 5–6. `ClaudeTranscriptHit{session_id,cwd}` (Task 5) is constructed in Task 6's wiring and tests. `ResolveDeps` field names/borrow shapes match between definition (Task 5) and use (Task 6: `as_deref()` against `Arc` matches the `&(dyn Fn ... + Send + Sync)` field type). `RESOLVE_MATCH_CAP` is defined once (Task 5) and asserted in tests. `SessionMetadataStore::new(dir)` appends `session-metadata.json` — Task 6's overlay test writes that exact filename into the dir it passes. + +**4. Load-bearing-assumption revision (2026-07-29).** A validation pass falsified four assumptions; this plan was revised accordingly and the self-review items above were re-applied to every edited task. A2 (V2-zod-truth): Task 6's 400 `details` literals were zod v3 wording — rewritten to the probed zod 4.3.6 wire output (received-type message suffixes via a `received_type` helper, `origin`/`inclusive` fields, double-quoted singular/plural `Unrecognized key(s)` form, `expected`/`origin`-before-`code` key order pinned by a serialized-string test, input-issue-before-`unrecognized_keys` array order pinned by a new multi-issue test), the body parse-failure path now degrades to `{}` (Node's absent-body `req.body ?? {}`) instead of `Null`, and the Global Constraints/module doc now record that NO consumer reads `details`, that the literals are zod-4.3.6-version-fragile (re-probe on bumps), and the accepted Express-HTML-400 / body-limit / 405-method deviations. A3 (V3-opencode-sqlite): Task 3's bare `SELECT directory` diverged from Node on 4 of 9 executed variants (D1-D4) — replaced with a bug-for-bug port of `resolveOpencodeSessionRoots` (legacy-schema early HIT with no existence check, truthy-directory filter, orphan/cycle ⇒ miss via a seen-set parent walk) plus an 11-case fixture suite covering every probed variant; Task 5's fallback docs and a new omitted-`cwd` test cover the `directory: None` hit. A4 + A14 (V4-semantics-diff, V7-deleted-overrides): the raw-snapshot membership claim was falsified — the Task 6 handler now drops `deleted`-overridden sessions via the SYNC `SettingsStore::session_overrides()` read (composite-key-only, matching Node's post-filter `getProjects()` AND the Rust sidebar's own `apply_session_overrides`; the exact-id fallbacks bypass the filter as Node's do, per comment), with `ResolveState.settings` wired from the same `settings_store.clone()` pattern as `SessionDirectoryState` and pinned by a new handler test; the remaining membership/ordering/locator deltas (enabledProviders gate, 256 KiB snippet window, cold-start window, tie-order/recency, A6 claude-locator deltas) are recorded as accepted deviations in the Parity Reference and Task 4 rather than silently claimed as parity. Also folded in: V1's 405-method note, V1's warmed-empty-index note (already honored — warming tests keep `session_index: None`), and Task 8's `npm ci` precondition (the worktree ships without `node_modules`; Playwright's globalSetup builds but does not install).

NODE PARITY NOTE (document in a comment on `scan_failures()`): Node behaves exactly this way — a throwing `listSessionFiles()` also yields an empty file list and lets the full-scan prune drop that provider's cached entries (`session-indexer.ts:1467-1475`, `:1499-1504`); what makes the outage VISIBLE is the recorded scan failure, which the route merges into `providerErrors` and marks the response `degraded` — never a silent healthy `ready + matches: []`.

OpenCode wire parity: Node's production worker boundary strips .code (worker serializes {name,message} only; runner rebuilds Error without code), so the wire is message-only. Production closure now maps OpencodeByIdError to ProviderFailure{code: None}, logs the internal SQLITE_* code via tracing; core + endpoint tests assert code-ABSENT wire shape; Task 4 doc + Self-Review 1b reworded (internal code = logging/message fidelity, not wire). 2. Claude locator roots: locate_transcript_checked now takes projects_roots as a parameter (Node's locator takes projectsDir); caller resolves CLAUDE_HOME||$HOME/.claude + /projects (Node getSessionRoots parity; claude_home_candidates explicitly forbidden - CLAUDE_CONFIG_DIR root excluded); global two-pass direct-then-subagent ordering with precedence test (f). 3. errno_code preserves the raw OS errno symbolically via libc (EPERM stays EPERM; EIO/EMFILE/ENOTDIR/etc. covered; unknown => None; non-unix kind-based fallback) with unit tests incl. EPERM!=EACCES. 4. 64 KiB cwd scan parses EVERY segment including the final one (Node split('\n') has no discard-tail rule); new tests (g) complete final line without trailing newline parses, (h) boundary-straddling fragment skipped without error. 5. settings_store.rs legacy migration DEFAULTS widens to four providers (adds amplifier, mirroring Node DEFAULT_ENABLED_CLI_PROVIDERS); legacy [claude,codex] migration test added. 6. Checked-locator tests hermetic by construction (injected temp roots, zero env mutation; CLAUDE_ENV_LOCK + EnvVarsRestore pattern cited if ever needed).

The tests: (a) gate the permission test with `#[cfg(unix)]` (`std::os::unix::fs::PermissionsExt` does not exist on Windows — an ungated test would not COMPILE there): chmod the projects dir to `0o000`, then FIRST probe `std::fs::read_dir(&projects)` directly — if the probe unexpectedly SUCCEEDS (running as root / CAP_DAC_OVERRIDE bypasses mode bits), restore permissions, `eprintln!("skipping: euid bypasses permission checks");` and `return`; otherwise assert `locate_transcript_checked` yields `Err` with `kind() == PermissionDenied`; restore permissions afterward so cleanup works; (b) a missing projects dir yields `Ok(None)`; (c) a transcript placed at `///subagents/.jsonl` IS found by `locate_transcript_checked` (the child-session layout); (d) ENOTDIR absence parity: a candidate path whose component is a REGULAR FILE (e.g. `/` created as a file, so descending into it fails with `NotADirectory`) yields `Ok(None)`, not `Err` — Node reports a normal miss for `ENOTDIR` (`claude-transcript-locator.ts:33-37`); (e) bounded cwd scan: a transcript whose only `cwd`-bearing JSON line starts BEYOND the first 64 KiB (pad with ~65 KiB of valid no-cwd JSONL first) makes `transcript_cwd_checked` return `Ok(None)` — proving the 64 KiB prefix bound, Node parity; (f) two-pass precedence: the SAME id present at BOTH the direct layout in one root AND the subagent layout — with a single root, and again with two roots where root A holds only the subagent copy and root B holds the direct copy — `locate_transcript_checked` returns the DIRECT path (B's direct copy beats A's subagent copy: pass 1 exhausts ALL roots first, Node's global order); (g) final-fragment parse parity: a transcript SMALLER than 64 KiB whose ONLY `cwd`-bearing JSON line is the LAST line and has NO trailing newline → `transcript_cwd_checked` returns `Ok(Some(cwd))` (Node's `split('\n')` parses the final segment); (h) truncated-tail tolerance: a JSON object that STRADDLES the 64 KiB boundary (starts inside the prefix, ends beyond it) is skipped without error — `Ok(None)` when no earlier line carries a cwd. 3b. `crates/freshell-server/src/main.rs` — final wiring (replaces the Task-3/4 temporaries).

On a legacy-schema opencode DB (universal-HIT by-id lookup), any wrong-length `ses_*` token produced a FALSE exact hit where Node answers a miss with zero work. - There was NO per-request fallback budget: up to MAX_RESUME_CANDIDATES = 8 fallback invocations per request (each claude one a full projects-dir scan), while Node's withRequestBudget caps each fallback at FALLBACK_BUDGET_PER_REQUEST = 2 REAL invocations per request. A third fallback-requiring token resolved on Rust but is not-found on Node. Mirror Node exactly (resolve-fallbacks.ts withRequestBudget semantics): - Full-id shape gates: `^[0-9a-fA-F]{8}-…-[0-9a-fA-F]{12}$` for the claude fallback (replacing the equivalent-but-implicit `kind == Uuid` check with Node's explicit shape), `^ses_[0-9a-zA-Z]{26}$` for opencode. - FALLBACK_BUDGET_PER_REQUEST = 2, ONE counter PER FALLBACK (Node's budgeted() closes over a separate `used` per key), fresh per request, checked shape-FIRST budget-SECOND (Node: "order is load-bearing" — a wrong-shape token must not consume budget), consumed by the real invocation itself, hit or miss. - The inline comment that falsely claimed the old gates matched "Node's budgeted fallbacks" now describes the actual mirrored semantics. Also bound the claude fallback's transcript cwd read (main.rs wiring) to Node's CWD_SCAN_BYTES = 64 KiB: new transcript_cwd_bounded() reads at most the first 64 KiB, splits on newline, and parses every segment INCLUDING the final unterminated one (Node's head.split('\n') loop has no discard-the-tail rule) — the hardened plan (Task 3a/3b, docs/plans/2026-07-30-rust-resolve-parity-hardened.md:1807) explicitly forbids mirroring the unbounded BufRead::lines() transcript_cwd for resolve, where one request could scan a multi-GB transcript. transcript_cwd itself is untouched for its other consumers; the error-PROPAGATING checked variant stays deferred to plan Task 3. Tests (crates/freshell-sessions/tests/resume_resolve.rs + claude_snapshot.rs unit tests): - wrong-length/wrong-charset ses_* tokens never reach the opencode fallback (panicking lookup) and yield ready-empty, - the claude gate accepts a full UUID in any hex case and rejects bare hex-prefix tokens, - a third fallback-requiring ses_ token in one request is budget-gated (exactly 2 real lookups, not-found even though the third would hit), - shape-gated tokens do not consume budget (a valid id after two wrong-shape ones still resolves), - budgets are tracked per provider (two opencode misses do not exhaust the claude budget), - transcript_cwd_bounded never scans past the 64 KiB prefix and still parses a complete unterminated final line. --- .../src/claude_snapshot.rs | 96 +++++++++ crates/freshell-freshagent/src/lib.rs | 2 +- crates/freshell-server/src/main.rs | 8 +- .../freshell-sessions/src/resume_resolve.rs | 152 +++++++++----- .../freshell-sessions/tests/resume_resolve.rs | 190 ++++++++++++++++++ 5 files changed, 398 insertions(+), 50 deletions(-) diff --git a/crates/freshell-freshagent/src/claude_snapshot.rs b/crates/freshell-freshagent/src/claude_snapshot.rs index fd1bcde81..ba5fdb105 100644 --- a/crates/freshell-freshagent/src/claude_snapshot.rs +++ b/crates/freshell-freshagent/src/claude_snapshot.rs @@ -87,6 +87,53 @@ pub fn transcript_cwd(path: &Path) -> Option { None } +/// Node's `CWD_SCAN_BYTES` (`claude-transcript-locator.ts:31`): the resolve +/// endpoint's cwd read never scans past the first 64 KiB of a transcript. +const CWD_SCAN_BYTES: u64 = 64 * 1024; + +/// Bounded variant of [`transcript_cwd`] for the resume-resolve claude +/// exact-id fallback (`crates/freshell-server/src/main.rs`).

Undisclosed MATCHING-SEMANTICS divergences remained; the in-code record is what a follow-up implementer relies on, so both module docs (freshell-sessions/src/resume_resolve.rs, freshell-server/src/resolve.rs) now enumerate every remaining divergence: - opencode by-id fallback runs the RETIRED resolveOpencodeSessionRoots parent-walk, not Node's hardened direct row query (providers/opencode-by-id-query.ts): orphaned/cyclic child rows are a Rust MISS where Node HITs; a legacy-schema DB is a Rust universal HIT for any full-shape ses_* id where Node hits only real rows; Rust hits omit Node's title/lastActivityAt. - fallback hits hardcode sessionType "claude"/"opencode" instead of consulting the session-metadata overlay (Node's sessionTypeFor) — a freshclaude/freshopencode session resolved via fallback would resume under the wrong runtime. - the claude fallback's locate_transcript probes //.jsonl and never Node's //subagents/.jsonl layout, so subagent child transcripts miss; read errors are swallowed as misses (no provider-error channel). The cwd read IS now bounded to Node's 64 KiB (previous commit); the checked locator + error propagation stay deferred to the hardened plan's Task 3. - response surface: degraded/providerErrors/unsearchedProviders/homeDir and the scan-failure/warming merge (plan Tasks 3, 5, 6). Stale doc refs fixed in the same blocks: - resume_resolve.rs referenced nonexistent 'resolveOpencodeSessionIds' (real name: resolveOpencodeSessionRoots). - parse/opencode.rs by-id doc said the walk is 'consumed by resolve-session.ts:59-85' — stale: hardened Node consumes resolve-session.ts -> resolve-fallbacks.ts -> the by-id worker (a direct row query); the walk remains only the Rust fallback's interim lookup, recorded as a divergence. Checklist (SYNC-06, 2026-07-14-rust-tauri-parity-completion-checklist.md): the entry claimed the Rust port 'matches the HARDENED in-tree matching semantics' with a DEFERRED list naming only the response surface, while budgeted/shape-gated fallbacks (now genuinely ported, previous commit) and the by-id lookup / sessionType-overlay / subagent-locator gaps are matching behavior. Rewritten truthfully: AT PARITY = parser (fixture anti-drift), matching core incl.

Cross-language anti-drift: `test/fixtures/resume-input/parser-cases.json` (32 cases) is now GENUINELY consumed by BOTH `test/unit/shared/resume-input-parser.test.ts` (fixture-driven describe) and `crates/freshell-sessions/tests/resume_input_parser_parity.rs`. Logic parity: `crates/freshell-sessions/tests/resume_resolve.rs` mirrors the MATCHING-SEMANTICS subset of `test/integration/server/sessions-resolve-router.test.ts` (the in-tree hardened suite runs 25 tests; its degraded/providerErrors/homeDir coverage is deferred with the surface above). MISSING: the deferred response surface, the flag + e2e matrix re-enable, and the `PW-TAURI-WIN` (native Windows WebView2) half of the named validation — left to the hardened plan / dependent tickets, per the SYNC-05/SAFE-11 PARTIAL convention. + - PARTIAL / REOPENED (2026-07-30): the first pass of this port targeted the RETIRED pre-#586 Node resolve implementation; an independent review reopened it. AT PARITY: (a) the parser — `crates/freshell-sessions/src/resume_input.rs` ports `shared/resume-input-parser.ts` (uuid/prefixed-id/hex-prefix extraction, the known-family prefixed-id regex, the `MAX_RESUME_CANDIDATES = 8` work budget, hints), cross-language anti-drift via `test/fixtures/resume-input/parser-cases.json` (32 cases) GENUINELY consumed by BOTH `test/unit/shared/resume-input-parser.test.ts` and `crates/freshell-sessions/tests/resume_input_parser_parity.rs`; (b) the matching CORE — `crates/freshell-sessions/src/resume_resolve.rs` ports `resolve-session.ts`'s per-token exact→fallback→prefix ordering (a prefix match never outranks an exact-id fallback), uuid/hex-only case-insensitivity (`ses_` base62 ids match case-SENSITIVELY), subagent exclusion from prefix discovery, cap-20/dedupe, `sessionType` always emitted (`sessionType ?? provider`), AND `resolve-fallbacks.ts`'s budgeted shape-gated fallbacks: full-id shape gates matching Node's `FALLBACK_ID_SHAPES` exactly (`^ses_[0-9a-zA-Z]{26}$` / full-UUID), `FALLBACK_BUDGET_PER_REQUEST = 2` real invocations per fallback per request (one counter PER fallback, shape checked BEFORE budget so wrong-shape tokens neither work nor consume budget), plus the claude fallback's cwd read bounded to Node's 64 KiB `CWD_SCAN_BYTES` (`transcript_cwd_bounded`); (c) the route shell — `crates/freshell-server/src/resolve.rs` (`POST /api/sessions/resolve`: auth, 400-validation pinned to zod 4.3.6 wire literals, warming, deleted-override filter). Logic parity tests: `crates/freshell-sessions/tests/resume_resolve.rs` mirrors the matching-semantics subset of `test/integration/server/sessions-resolve-router.test.ts` plus shape-gate/budget coverage. DEFERRED (all remaining divergences, enumerated in the module docs of `resume_resolve.rs`/`resolve.rs` and tracked in `docs/plans/2026-07-30-rust-resolve-parity-hardened.md`): (1) matching semantics — the opencode by-id fallback still runs the RETIRED `resolveOpencodeSessionRoots` parent-walk instead of Node's hardened direct row query (`providers/opencode-by-id-query.ts`): orphaned/cyclic child rows miss where Node hits, a legacy-schema DB universally hits any full-shape `ses_*` id where Node hits only real rows, and hits omit Node's `title`/`lastActivityAt`; fallback hits hardcode `sessionType` `"claude"`/`"opencode"` instead of consulting the session-metadata overlay (Node's `sessionTypeFor`) — a freshclaude/freshopencode session resolved via fallback would resume under the wrong runtime; the claude fallback's `locate_transcript` never probes Node's `//subagents/.jsonl` layout, so subagent child transcripts miss; (2) response surface (plan Tasks 3, 5, 6) — `degraded` status, `providerErrors`, `unsearchedProviders`, `homeDir`, warming/ready readiness merge (the wired fallbacks map read errors to a MISS, never a provider error). Until ALL of that lands, the `sessionResolve` capability flag is rolled back to `false` (`build_platform_payload`, `main.rs`) and `test/e2e-browser/specs/resume-button.spec.ts` is removed from `MATRIX_SPECS` (chromium-only again). MISSING: the deferred items above, the flag + e2e matrix re-enable, and the `PW-TAURI-WIN` (native Windows WebView2) half of the named validation — left to the hardened plan / dependent tickets, per the SYNC-05/SAFE-11 PARTIAL convention. ## Final release gates From 22e75dd3fef8eb4f2754c6be454afd03981aeb58 Mon Sep 17 00:00:00 2001 From: Dan Shapiro <3732858+danshapiro@users.noreply.github.com> Date: Thu, 30 Jul 2026 20:03:48 -0700 Subject: [PATCH 28/52] test(sessions): pin thread_/task_ known families and the {8,64} suffix bound in the shared fixture MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Residual fixture delta atop 13a342817's already-landed Task 2 work: the known-family prefix regex and MAX_RESUME_CANDIDATES=8 cap are already committed on both sides, but the anti-drift table had no positive thread_/task_ family case and no suffix longer than 40 chars (the old Rust regex capped at 40, so a regression there would go uncaught).

All four real sources participate in failure tracking: direct-listed (opencode) and file-backed (claude/codex/ amplifier) root-listing failures are recorded, never silently treated as an empty listing.

See `docs/plans/2026-07-29-resume-session-button.md`. - **Playwright validation (`PW-RUST`, `PW-TAURI-WIN`):** With the flag declared, the sidebar shows the pinned Resume button; pasting a known session id resumes it in a tab (mirror `test/e2e-browser/specs/resume-button.spec.ts`). - PARTIAL / REOPENED (2026-07-30): the first pass of this port targeted the RETIRED pre-#586 Node resolve implementation; an independent review reopened it. AT PARITY: (a) the parser — `crates/freshell-sessions/src/resume_input.rs` ports `shared/resume-input-parser.ts` (uuid/prefixed-id/hex-prefix extraction, the known-family prefixed-id regex, the `MAX_RESUME_CANDIDATES = 8` work budget, hints), cross-language anti-drift via `test/fixtures/resume-input/parser-cases.json` (32 cases) GENUINELY consumed by BOTH `test/unit/shared/resume-input-parser.test.ts` and `crates/freshell-sessions/tests/resume_input_parser_parity.rs`; (b) the matching CORE — `crates/freshell-sessions/src/resume_resolve.rs` ports `resolve-session.ts`'s per-token exact→fallback→prefix ordering (a prefix match never outranks an exact-id fallback), uuid/hex-only case-insensitivity (`ses_` base62 ids match case-SENSITIVELY), subagent exclusion from prefix discovery, cap-20/dedupe, `sessionType` always emitted (`sessionType ?? provider`), AND `resolve-fallbacks.ts`'s budgeted shape-gated fallbacks: full-id shape gates matching Node's `FALLBACK_ID_SHAPES` exactly (`^ses_[0-9a-zA-Z]{26}$` / full-UUID), `FALLBACK_BUDGET_PER_REQUEST = 2` real invocations per fallback per request (one counter PER fallback, shape checked BEFORE budget so wrong-shape tokens neither work nor consume budget), plus the claude fallback's cwd read bounded to Node's 64 KiB `CWD_SCAN_BYTES` (`transcript_cwd_bounded`); (c) the route shell — `crates/freshell-server/src/resolve.rs` (`POST /api/sessions/resolve`: auth, 400-validation pinned to zod 4.3.6 wire literals, warming, deleted-override filter). Logic parity tests: `crates/freshell-sessions/tests/resume_resolve.rs` mirrors the matching-semantics subset of `test/integration/server/sessions-resolve-router.test.ts` plus shape-gate/budget coverage. DEFERRED (all remaining divergences, enumerated in the module docs of `resume_resolve.rs`/`resolve.rs` and tracked in `docs/plans/2026-07-30-rust-resolve-parity-hardened.md`): (1) matching semantics — the opencode by-id fallback still runs the RETIRED `resolveOpencodeSessionRoots` parent-walk instead of Node's hardened direct row query (`providers/opencode-by-id-query.ts`): orphaned/cyclic child rows miss where Node hits, a legacy-schema DB universally hits any full-shape `ses_*` id where Node hits only real rows, and hits omit Node's `title`/`lastActivityAt`; fallback hits hardcode `sessionType` `"claude"`/`"opencode"` instead of consulting the session-metadata overlay (Node's `sessionTypeFor`) — a freshclaude/freshopencode session resolved via fallback would resume under the wrong runtime; the claude fallback's `locate_transcript` never probes Node's `//subagents/.jsonl` layout, so subagent child transcripts miss; (2) response surface (plan Tasks 3, 5, 6) — `degraded` status, `providerErrors`, `unsearchedProviders`, `homeDir`, warming/ready readiness merge (the wired fallbacks map read errors to a MISS, never a provider error). Until ALL of that lands, the `sessionResolve` capability flag is rolled back to `false` (`build_platform_payload`, `main.rs`) and `test/e2e-browser/specs/resume-button.spec.ts` is removed from `MATRIX_SPECS` (chromium-only again). MISSING: the deferred items above, the flag + e2e matrix re-enable, and the `PW-TAURI-WIN` (native Windows WebView2) half of the named validation — left to the hardened plan / dependent tickets, per the SYNC-05/SAFE-11 PARTIAL convention. + - PARTIAL (2026-07-30, hardened-contract follow-up, commit `48b67f838`): rebased onto `f903e8a6` (#586) and closed the hardening delta.

OpenCode health gated on the mtime token (directory_index.rs): a db that becomes locked/unreadable WITHOUT an mtime change (chmod moves ctime, not mtime; locks move nothing) kept answering ready from stale evidence. The sweep now consults a per-sweep direct_health_check() whenever the change token is unchanged (Node parity: refreshDirectProvider() runs on every full scan) — the token still gates only the expensive re-query of session DATA. OpencodeProvider gains health_check() (read-only open + one sqlite_master page read, the same open path direct_list uses). The masking test's artificial always-changing token was replaced with a CONSTANT token, plus a real-OpencodeSource chmod-000 test proving unchanged-mtime outages are recorded and cached sessions preserved. 2. TOCTOU in file-backed discovery (directory_index.rs, amplifier.rs): the disposable ensure_root_listable() preflight followed by a second, error-swallowing read_dir meant a failure between the two calls — or a per-entry iterator error — returned Ok(empty), CLEARING the provider's scan failure and pruning its cache from a sweep that never listed anything. Claude/codex/amplifier discover_checked() are now SINGLE-PASS: the one read_dir handle opened (open_root_dir) is the one traversed, and root per-entry errors propagate with `?`. Missing roots stay a genuine empty; nested errors stay tolerant (Node parity). New tests exercise the REAL sources (chmod-000 roots), not injected discover_checked doubles. 3. Torn snapshot/failure reads (directory_index.rs, resolve.rs): the snapshot and scan_failures published under separate locks at separate times, so a request could pair a failed-scan empty snapshot with a subsequently cleared failure set (healthy-looking ready+matches:[]) or a recovered snapshot with stale failures. scan_failures now lives INSIDE CachedSnapshot — one lock write publishes the whole generation — and the route takes ONE coherent read via the new snapshot_with_failures() instead of two temporally separated reads. Short-lock discipline preserved (nothing held across a sweep or await). New atomic-generation test pins that no incoherent pair is ever observable.

Now HOME-then-USERPROFILE - an APPROXIMATION of Node's os.homedir(), not its actual platform contract (Windows os.homedir() reads USERPROFILE and never consults HOME; POSIX falls back to the passwd entry when HOME is unset) - aligned with the then-existing homeDir wire-field resolution. Exact os.homedir() platform semantics landed in a later commit on this branch ("fix(server,sessions): resolve user home via Node os.homedir() platform semantics"). Pinned by provider_home_falls_back_to_userprofile_when_home_unset and provider_home_prefers_home_over_userprofile; the none-case test now clears USERPROFILE too. 2. The resolve route awaited the whole spawn_blocking resolver with no deadline: a filesystem/SQLite op stalled outside SQLite's 500ms busy handling held the request and a blocking-pool worker forever. The route now bounds the ENTIRE resolver task with a 15s RESOLVE_OUTER_DEADLINE. The 15s value is borrowed from Node's by-id runner timeout (opencode-by-id-runner.ts DEFAULT_TIMEOUT_MS), but the SCOPE is not Node's: Node applies that timeout per individual worker, not around the whole resolver - a later commit on this branch rescoped the deadline to each fallback dispatch to match. On elapse the task is abandoned (recorded deviation: blocking tasks cannot be cancelled, Node terminates its worker) and the request answers a degraded 200 with message-only providerErrors (every enabled provider reported unsearchable, never a healthy-looking not-found), hint preserved, refresh fire-and-forgotten. Deadline injectable via ResolveState.resolve_deadline; pinned by a_stalled_resolver_answers_degraded_at_the_outer_deadline_never_hangs. 🤖 Generated with [Amplifier](https://github.com/microsoft/amplifier) Co-Authored-By: Amplifier <240397093+microsoft-amplifier@users.noreply.github.com> --- crates/freshell-server/src/main.rs | 4 + crates/freshell-server/src/resolve.rs | 164 ++++++++++++++++-- .../freshell-server/src/session_directory.rs | 78 ++++++++- 3 files changed, 233 insertions(+), 13 deletions(-) diff --git a/crates/freshell-server/src/main.rs b/crates/freshell-server/src/main.rs index 443fd5d89..0c484a8e8 100644 --- a/crates/freshell-server/src/main.rs +++ b/crates/freshell-server/src/main.rs @@ -1347,6 +1347,10 @@ async fn main() -> ExitCode { home_dir: std::env::var_os("HOME") .or_else(|| std::env::var_os("USERPROFILE")) .map(|h| Arc::new(h.to_string_lossy().into_owned())), + // Node's hard 15 s by-id runner timeout, applied as the route's + // outer deadline on the whole blocking resolver (see + // `resolve.rs` for the abandonment semantics). + resolve_deadline: resolve::RESOLVE_OUTER_DEADLINE, })) .merge(files::router(files_state)) .merge(repo_icon::router(repo_icon_state)) diff --git a/crates/freshell-server/src/resolve.rs b/crates/freshell-server/src/resolve.rs index 291e0fbff..fb3f480b4 100644 --- a/crates/freshell-server/src/resolve.rs +++ b/crates/freshell-server/src/resolve.rs @@ -45,7 +45,12 @@ //! the async runtime, and per-request work is bounded by //! `MAX_RESUME_CANDIDATES` (8) × `FALLBACK_BUDGET_PER_REQUEST` (2 per //! provider) fallback calls + one index scan per token.

From 8b03fdace6e6a912bf580a05d052aabb288e78a6 Mon Sep 17 00:00:00 2001 From: Dan Shapiro <3732858+danshapiro@users.noreply.github.com> Date: Fri, 31 Jul 2026 01:09:51 -0700 Subject: [PATCH 40/52] fix(server): resolve claude fallback + homeDir via provider_home and cap resolver tasks with permit-scoped admission + cooperative cancel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Finding 1 (native Windows/Tauri claude fallback): the exact-id claude locator read only CLAUDE_HOME || HOME/.claude, so the documented USERPROFILE-only Tauri environment answered a healthy-looking ready-empty where Node (os.homedir()) finds the transcript. Extract the locator body to resolve_claude_exact_id_fallback() and route its home — plus the homeDir wire field (which also accepted an EMPTY HOME verbatim) and the opencode data-home helper in freshell-sessions — through the shared HOME||USERPROFILE, empty-as-unset resolution (provider_home() / a pure home_dir_from()). Tested at the fallback itself: a USERPROFILE-only env with a .claude transcript fixture now resolves it. Finding 2 (blocking-pool exhaustion): the 15s outer deadline bounded only the HTTP wait — an abandoned spawn_blocking resolver ran on (and repeated requests could accumulate stalled tasks until Tokio's blocking pool exhausted). Now: (a) an 8-permit semaphore whose permit MOVES INTO the blocking task caps concurrent (abandoned included) resolver tasks; a permit-starved request degrades within the same deadline with the same timeout-shaped 200 instead of queueing; (b) a cancel flag checked before every fallback invocation stops an abandoned resolver at its next fallback boundary. Precisely: task COUNT is bounded and provider work stops at fallback boundaries — an individual stalled FS/SQLite op inside a fallback still cannot be killed and holds its permit until it returns (recorded deviation from Node's worker.terminate()). Node's 15s degraded response shape is unchanged. Tests: fallback-level USERPROFILE-only resolution; empty-HOME fallthrough for the homeDir helper, provider_home(), and the opencode home helper; permit saturation degrades request N+1 without invoking an (N+1)th resolver body and the abandoned task returns its permit when its op completes; a cancelled resolver skips the second fallback invocation (with a non-cancelled control proving two would otherwise run). 🤖 Generated with [Amplifier](https://github.com/microsoft/amplifier) Co-Authored-By: Amplifier <240397093+microsoft-amplifier@users.noreply.github.com> --- crates/freshell-server/src/main.rs | 236 +++++++++---- crates/freshell-server/src/resolve.rs | 315 ++++++++++++++++-- .../freshell-server/src/session_directory.rs | 46 ++- .../freshell-sessions/src/parse/opencode.rs | 59 +++- 4 files changed, 568 insertions(+), 88 deletions(-) diff --git a/crates/freshell-server/src/main.rs b/crates/freshell-server/src/main.rs index 0c484a8e8..e250c8267 100644 --- a/crates/freshell-server/src/main.rs +++ b/crates/freshell-server/src/main.rs @@ -1290,67 +1290,22 @@ async fn main() -> ExitCode { // (Node preserves `cause.code` verbatim).

The wiring snippets now describe the LANDED behavior — resolve_claude_exact_id_fallback() and resolve_wire_home_dir() in main.rs, both resolving homes via session_directory::provider_home() (HOME then USERPROFILE, empty treated as unset) — and a new verifier list names the landed tests, including the USERPROFILE-only exact-id fallback test claude_exact_id_fallback_finds_transcript_in_a_userprofile_only_environment. 2. 2026-07-29-rust-resolve-parity.md: added an unmissable ARCHIVED / SUPERSEDED / DO NOT EXECUTE banner at the top. The plan implements the retired pre-#586 OpenCode parent-chain resolver contract, its parity reference (lines ~62-72) describes the obsolete pre-#586 behavior, and its expected test counts (~line 3103) are stale; re-executing it would reintroduce defects resolved by the hardened plan. Body unchanged — the banner is the fix. 3. 2026-07-29-rust-resolve-parity-spec.md: Requirement 8 said "Mark SYNC-06 done" while the same spec declares the required PW-TAURI-WIN validation out of scope and the implementation plan requires the checkbox stay unchecked. Resolved in favor of the plan/checklist: the spec now instructs recording the evidence as a PARTIAL bullet with the checkbox left UNCHECKED, and the Goal is reworded to "deliver the Rust-server half" so no instruction contradicts the out-of-scope declaration. 🤖 Generated with [Amplifier](https://github.com/microsoft/amplifier) Co-Authored-By: Amplifier <240397093+microsoft-amplifier@users.noreply.github.com> --- .../2026-07-29-rust-resolve-parity-spec.md | 22 ++++++--- docs/plans/2026-07-29-rust-resolve-parity.md | 24 ++++++++++ ...2026-07-30-rust-resolve-parity-hardened.md | 48 +++++++++++++------ 3 files changed, 73 insertions(+), 21 deletions(-) diff --git a/docs/plans/2026-07-29-rust-resolve-parity-spec.md b/docs/plans/2026-07-29-rust-resolve-parity-spec.md index 587fe5bb5..b0e0f2fc3 100644 --- a/docs/plans/2026-07-29-rust-resolve-parity-spec.md +++ b/docs/plans/2026-07-29-rust-resolve-parity-spec.md @@ -2,8 +2,10 @@ ## Goal -Close checklist item **SYNC-06** in -`docs/plans/2026-07-14-rust-tauri-parity-completion-checklist.md:803`: implement +Deliver the Rust-server half of checklist item **SYNC-06** in +`docs/plans/2026-07-14-rust-tauri-parity-completion-checklist.md:803` (the item itself +stays unchecked until its `PW-TAURI-WIN` native-Windows validation, out of scope here, +also lands — see Requirement 8): implement `POST /api/sessions/resolve` in the **Rust server** (`crates/freshell-server`) with full behavior parity to the Node implementation, and declare the `sessionResolve` feature flag from the Rust server so the shared client shows the pinned sidebar Resume button on @@ -85,11 +87,17 @@ Rust endpoint's JSON must be wire-compatible with what the client already consum 7. **Feature flag.** Declare `sessionResolve` in the Rust server's feature-flags payload (its equivalent of `detectFeatureFlags()`), so the shared client renders the Resume button.

Logic parity tests: `crates/freshell-sessions/tests/resume_resolve.rs` mirrors the matching-semantics subset of `test/integration/server/sessions-resolve-router.test.ts` plus shape-gate/budget coverage. DEFERRED (all remaining divergences, enumerated in the module docs of `resume_resolve.rs`/`resolve.rs` and tracked in `docs/plans/2026-07-30-rust-resolve-parity-hardened.md`): (1) matching semantics — the opencode by-id fallback still runs the RETIRED `resolveOpencodeSessionRoots` parent-walk instead of Node's hardened direct row query (`providers/opencode-by-id-query.ts`): orphaned/cyclic child rows miss where Node hits, a legacy-schema DB universally hits any full-shape `ses_*` id where Node hits only real rows, and hits omit Node's `title`/`lastActivityAt`; fallback hits hardcode `sessionType` `"claude"`/`"opencode"` instead of consulting the session-metadata overlay (Node's `sessionTypeFor`) — a freshclaude/freshopencode session resolved via fallback would resume under the wrong runtime; the claude fallback's `locate_transcript` never probes Node's `//subagents/.jsonl` layout, so subagent child transcripts miss; (2) response surface (plan Tasks 3, 5, 6) — `degraded` status, `providerErrors`, `unsearchedProviders`, `homeDir`, warming/ready readiness merge (the wired fallbacks map read errors to a MISS, never a provider error). Until ALL of that lands, the `sessionResolve` capability flag is rolled back to `false` (`build_platform_payload`, `main.rs`) and `test/e2e-browser/specs/resume-button.spec.ts` is removed from `MATRIX_SPECS` (chromium-only again).

Note: origin/feat/rust-resolve-parity still holds the pre-correction history, so publishing this branch will require a deliberate `git push --force-with-lease` by the user. ## Final release gates From 6b62104ccc05aebb43ee77c0e8c3a4856c25a256 Mon Sep 17 00:00:00 2001 From: Dan Shapiro <3732858+danshapiro@users.noreply.github.com> Date: Fri, 31 Jul 2026 02:01:57 -0700 Subject: [PATCH 43/52] fix(server,sessions): resolve user home via Node os.homedir() platform semantics Correct the interim HOME->USERPROFILE approximation (commits c6f3220b0 and bb357a598 applied HOME-then-USERPROFILE on ALL platforms) to Node os.homedir() / libuv uv_os_homedir platform rules: Windows reads USERPROFILE and never consults HOME; POSIX reads HOME when set and non-empty, else the effective user's passwd-entry home (getpwuid_r) -- so POSIX now resolves a home (and main.rs builds a real session index, no permanent warming) even with HOME unset, and a Windows process with both variables set indexes USERPROFILE, never HOME. - session_directory::provider_home() and parse/opencode's home_dir() now delegate to std::env::home_dir() (un-deprecated since 1.87; MSRV 1.96), which implements exactly these platform semantics. The homeDir wire helper and the claude exact-id fallback in main.rs route through provider_home() and inherit the fix. Provider-specific overrides (CLAUDE_HOME/CODEX_HOME/FRESHELL_AMPLIFIER_HOME) keep their precedence. - Tests: the cross-platform HOME||USERPROFILE pins are replaced with platform-conditional ones -- cfg(unix) tests assert the passwd-entry fallback (via a getpwuid_r oracle) and that USERPROFILE is NEVER consulted; cfg(windows) tests pin USERPROFILE-wins-over-HOME. The opencode pure home_dir_from tests become env-mutating tests serialized on a new crate-wide HOME_ENV_TEST_LOCK (directory_index's persist-path test now takes the same lock). - docs: SYNC-06 ERRATA line recording the interim approximation and this correction. --- crates/freshell-server/src/main.rs | 141 +++++++++++++--- .../freshell-server/src/session_directory.rs | 147 ++++++++++++---- .../freshell-sessions/src/directory_index.rs | 9 +- crates/freshell-sessions/src/lib.rs | 9 + .../freshell-sessions/src/parse/opencode.rs | 158 ++++++++++++++---- .../freshell-sessions/src/resume_resolve.rs | 3 +- ...-rust-tauri-parity-completion-checklist.md | 1 + 7 files changed, 369 insertions(+), 99 deletions(-) diff --git a/crates/freshell-server/src/main.rs b/crates/freshell-server/src/main.rs index e250c8267..f6c012f06 100644 --- a/crates/freshell-server/src/main.rs +++ b/crates/freshell-server/src/main.rs @@ -1294,7 +1294,8 @@ async fn main() -> ExitCode { resolve_claude_exact_id_fallback(session_id) }) as crate::resolve::ClaudeLocator), // See `resolve_wire_home_dir` for the Node `os.homedir()` parity - // derivation (HOME then USERPROFILE, empty treated as unset). + // derivation (USERPROFILE on Windows; HOME else passwd-entry + // home on POSIX). home_dir: resolve_wire_home_dir(), // Node's hard 15 s by-id runner timeout, applied as the route's // outer deadline on the whole blocking resolver (see @@ -1712,9 +1713,10 @@ fn resolve_home() -> Option { /// The `homeDir` wire field for `POST /api/sessions/resolve`.

Corrected by this commit: `provider_home()`, the `homeDir` wire helper, the claude exact-id fallback root, and opencode's `home_dir()` now delegate to `std::env::home_dir()`, which implements Node's platform semantics exactly. ## Final release gates From 67c6ae1d010ff4a10961721dd632034285d81fd9 Mon Sep 17 00:00:00 2001 From: Dan Shapiro <3732858+danshapiro@users.noreply.github.com> Date: Fri, 31 Jul 2026 02:19:16 -0700 Subject: [PATCH 44/52] fix(server): scope resolve deadline/admission to the fallback dispatch (interim: a shared cancel flag still skipped and blamed later providers) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Corrects the earlier whole-resolver deadline/admission scoping (an interim approximation introduced by "fix(server): resolve claude fallback + homeDir via provider_home and cap resolver tasks with permit-scoped admission + cooperative cancel"): the 8-permit semaphore and the 15 s deadline previously wrapped the ENTIRE resolver - permit wait, input parsing, in-memory index matching, warming and no-candidate paths - so eight stalled fallbacks made every later request (exact index hits, garbage input, warming) wait for admission and then return a fabricated degraded result blaming every enabled provider. Node scopes its 15 s timeout to the individual by-id worker (opencode-by-id-runner.ts DEFAULT_TIMEOUT_MS); its cheap paths never wait on fallback-worker availability. This commit moves the deadline toward that scoping but does NOT fully reach Node's per-worker behavior: - each blocking fallback invocation now runs on its OWN spawn_blocking task via bounded_fallback(): permit wait + fallback bounded by the (renamed) RESOLVE_FALLBACK_DEADLINE, permit MOVED INTO the task so a stalled syscall holds it until it returns (accumulation still capped at RESOLVE_MAX_CONCURRENCY = 8), and a panicking fallback still resumes into the resolver task so the explicit 500 contract holds - parsing/validation, warming checks, index-only resolution, and no-candidate responses run WITHOUT a permit and WITHOUT the deadline and now succeed under full saturation - REMAINING DIVERGENCE from Node: one cooperative cancellation flag is SHARED across all of a request's fallback dispatches, so the first timeout skips every subsequent fallback - including other providers' never-dispatched work - and records fabricated timeout providerErrors for them. A timeout can therefore blame providers whose fallbacks were never dispatched, unlike Node, where a worker timeout affects only that worker's provider. Corrected in a later commit on this branch ("fix(resolve): bound each fallback dispatch independently - a timeout never skips or blames other providers"). Tests (RED first against the old scoping): exact index hit / garbage no-candidate input / warming all succeed with a zero-permit semaphore; the existing stall/starvation/cancel tests reshaped to pin the new scoping (request C exact hit succeeds while the only permit is still held).

Hardened parity was actually delivered by `1480e2a71` (hardened resolve wire: providerErrors/unsearchedProviders/homeDir, scan-failure merge, degraded refresh) and `22022a848` (capability + e2e matrix restore). CORRECTED IN-HISTORY (2026-07-31): both messages were reworded on this branch to accurately describe the retired legacy contract they implemented — now `e6e37c5d8` ("resume-resolve matching core for the retired pre-#586 legacy contract") and `fee2d2e3e` ("POST /api/sessions/resolve implementing the retired pre-#586 legacy contract"); the rewrite was message-only with identical trees.

Corrected by this commit: `provider_home()`, the `homeDir` wire helper, the claude exact-id fallback root, and opencode's `home_dir()` now delegate to `std::env::home_dir()`, which implements Node's platform semantics exactly. + - ERRATA (2026-07-31, resolve deadline/admission scoping): commit `bb357a598` wrapped the ENTIRE resolver — permit wait, in-memory index matching, warming and no-candidate paths — in the shared 8-permit admission semaphore and the 15 s deadline, an interim approximation that let saturated fallbacks degrade zero-I/O requests and blamed every enabled provider on a timeout. Corrected by this commit to Node's scoping (`opencode-by-id-runner.ts` bounds the individual by-id worker): the permit + deadline + cooperative-cancel machinery now bounds ONLY each blocking provider-fallback dispatch — parsing/validation, index-only resolution, warming, and no-candidate responses never queue for admission — and a timeout blames only the provider(s) whose fallbacks were actually dispatched. ## Final release gates From 502dd39d620afd2e1e657a4761064b40960e0fa2 Mon Sep 17 00:00:00 2001 From: Dan Shapiro <3732858+danshapiro@users.noreply.github.com> Date: Fri, 31 Jul 2026 02:24:47 -0700 Subject: [PATCH 45/52] docs(plans): convert hardened resolve-parity plan into an executed completion record The plan was fully implemented on feat/rust-resolve-parity but still read as an active, unchecked executable task sequence (blocking review finding).

Port Node's override lookup chain and its deleted/titleOverride application (session-indexer.ts:1173-1187 lookup chain, applyOverride at 204-220, consumed by resolve-session.ts:85): - lookup_session_override: composite key, then bare session id, then (claude only, when the transcript basename differs from the parsed session id) legacy 'claude:{basename}' then bare '{basename}' -- first present entry wins, matching Node's || chain. - project_session_through_overrides: 'deleted' hides the session; a non-empty 'titleOverride' replaces the title before matching. Other override fields (summary/createdAt/archived) never reach the resolve wire shape and are not projected. NOT ported here: Node's provider-generated titleSource suppression branch (applyOverride, session-indexer.ts:210-211 - a dir/first-message sourced titleOverride never clobbers a current provider-generated title). The Rust index did not yet track titleSource, so this projection unconditionally substitutes a non-empty titleOverride; the suppression branch was implemented in a later commit on this branch ("fix(resolve): port Node's provider-generated-title suppression into the override projection"). Tests (TDD, each watched fail RED first): - title_override_projects_onto_resolve_matches - bare_session_id_deleted_override_hides_prefix_matches - legacy_claude_composite_basename_deleted_override_hides_the_session - legacy_claude_bare_basename_deleted_override_hides_the_session The existing composite-key deletion test is unchanged. --- crates/freshell-server/src/resolve.rs | 199 +++++++++++++++++++++++--- 1 file changed, 182 insertions(+), 17 deletions(-) diff --git a/crates/freshell-server/src/resolve.rs b/crates/freshell-server/src/resolve.rs index 41d56bf3c..5f1256a18 100644 --- a/crates/freshell-server/src/resolve.rs +++ b/crates/freshell-server/src/resolve.rs @@ -423,6 +423,75 @@ fn bounded_fallback( }) } +/// Node's override-key lookup for ONE indexed session +/// (`buildProjectGroups`, `session-indexer.ts:1173-1186`): the composite +/// `"{provider}:{sessionId}"` key first, then the bare session id; only when +/// NEITHER hits and the session is a claude transcript whose file basename +/// differs from its parsed session id (a pre-sessionId-parsing-era override) +/// do the legacy keys apply — composite `"claude:{basename}"`, then the bare +/// basename.

charset=UTF-8 Content-Transfer-Encoding: 8bit ffa4aac1a's interim cooperative cancel flag was SHARED across both providers' fallback dispatches: once one dispatch timed out, every later fallback in the same request returned a fabricated timeout without invoking its provider. For input with an opencode ses_ id followed by a claude UUID, an opencode stall skipped the healthy claude lookup, omitted the claude match, and blamed claude for a timeout it never had — contradicting Node, which bounds each by-id worker individually, records the rejection for that ONE provider, and continues through later candidates/providers (resolve-session.ts:133-156, opencode-by-id-runner.ts per-worker timeout). Remove the shared flag: each dispatch keeps its own 15 s deadline and 8-permit admission (ffa4aac1a's scoping otherwise intact); a timeout blames only the provider whose dispatch elapsed, and later dispatches — same or other provider — run with their own bounds. Abandoned-task accumulation stays bounded WITHOUT the flag: the per-provider budget (2) caps dispatches within a request, the semaphore caps tasks across requests. Tests: new cross-provider pin (opencode stalls, claude healthy — claude match returned, only opencode blamed); the shared-flag skip test is reshaped to pin the corrected contract (second candidate's dispatch still runs; first-error-wins keeps one wire entry).

Corrected: admission is now a synchronous try_acquire_owned() BEFORE any fallback task exists. A permit-starved dispatch fails fast into the existing degraded provider-error shape ('resolve concurrency limit reached', message-only like Node's worker-timeout rejection) instead of queueing; the per-dispatch deadline now bounds only the admitted fallback task; per-provider blame and the cheap-path bypass (parsing, index-only, warming, no-candidate never touch admission) are unchanged. Node needs no analogue of this state: worker.terminate() reclaims its stalled worker at the timeout, so it never caps admission (opencode-by-id-runner.ts; resolve-session.ts:133-156 records the rejection per provider and continues). Tests: new permit_starvation_fails_fast_without_pinning_an_outer_worker _for_the_deadline proves a starved dispatch answers degraded well under a generous 5 s deadline with the fallback body never invoked (RED on the old code: it queued the full 5 s and answered the timeout shape). Strengthened saturated_permits_degrade_the_next_request_without_ spawning_another_resolver: request B now runs with a generous 10 s deadline and must answer within 2 s, so an implementation that queues for the deadline fails (the old 5 s allowance against a 100 ms deadline let a full-deadline queuer pass). Docs: ERRATA notes added to the hardened plan completion record and the parity checklist recording that the interim design admitted inside the outer worker. --- crates/freshell-server/src/resolve.rs | 215 +++++++++++++----- ...-rust-tauri-parity-completion-checklist.md | 1 + ...2026-07-30-rust-resolve-parity-hardened.md | 6 + 3 files changed, 165 insertions(+), 57 deletions(-) diff --git a/crates/freshell-server/src/resolve.rs b/crates/freshell-server/src/resolve.rs index 8ea5b7fee..5a242edac 100644 --- a/crates/freshell-server/src/resolve.rs +++ b/crates/freshell-server/src/resolve.rs @@ -51,15 +51,17 @@ //! no-candidate responses — is bounded THREE ways (Node scopes its 15 s //! timeout to the individual by-id worker, `opencode-by-id-runner.ts`; //! its cheap paths never wait on worker availability): (1) -//!

The Rust index carried no parse-layer title provenance, so this plumbs Node's ParsedSessionTitleSource (types.ts:100 — sole variant 'provider-generated', hence a bool) faithfully through the snapshot: - ParsedSessionMeta/IndexedSession gain title_provider_generated (serde(default) keeps pre-existing persisted parse-caches loadable); - claude parse sets it iff a custom-title/agent-name record produced the title (providers/claude.ts:505; Node's third input, the generated-summary-title extractor, has no ported extraction here so no Rust-parsed title can originate from it); - amplifier sets it iff the metadata 'name' is present (providers/amplifier.ts:93); codex/opencode never set it, like Node; - project_session_through_overrides now suppresses the override exactly per Node's negated conjunction — every other override source ('user', 'ai', 'legacy', absent) still substitutes. TDD: provider_generated_title_survives_dir_sourced_override and provider_generated_title_survives_first_message_sourced_override were RED first (title came back 'stale placeholder'); user_rename_still_overrides_a_provider_generated_title pins the suppression's scoping. Existing rename/deleted-override tests unchanged and green. Docs: ERRATA line in the parity completion checklist recording the omission and this correction.

AT PARITY: (a) the parser — `crates/freshell-sessions/src/resume_input.rs` ports `shared/resume-input-parser.ts` (uuid/prefixed-id/hex-prefix extraction, the known-family prefixed-id regex, the `MAX_RESUME_CANDIDATES = 8` work budget, hints), cross-language anti-drift via `test/fixtures/resume-input/parser-cases.json` (32 cases) GENUINELY consumed by BOTH `test/unit/shared/resume-input-parser.test.ts` and `crates/freshell-sessions/tests/resume_input_parser_parity.rs`; (b) the matching CORE — `crates/freshell-sessions/src/resume_resolve.rs` ports `resolve-session.ts`'s per-token exact→fallback→prefix ordering (a prefix match never outranks an exact-id fallback), uuid/hex-only case-insensitivity (`ses_` base62 ids match case-SENSITIVELY), subagent exclusion from prefix discovery, cap-20/dedupe, `sessionType` always emitted (`sessionType ?? provider`), AND `resolve-fallbacks.ts`'s budgeted shape-gated fallbacks: full-id shape gates matching Node's `FALLBACK_ID_SHAPES` exactly (`^ses_[0-9a-zA-Z]{26}$` / full-UUID), `FALLBACK_BUDGET_PER_REQUEST = 2` real invocations per fallback per request (one counter PER fallback, shape checked BEFORE budget so wrong-shape tokens neither work nor consume budget), plus the claude fallback's cwd read bounded to Node's 64 KiB `CWD_SCAN_BYTES` (`transcript_cwd_bounded`); (c) the route shell — `crates/freshell-server/src/resolve.rs` (`POST /api/sessions/resolve`: auth, 400-validation pinned to zod 4.3.6 wire literals, warming, deleted-override filter). Logic parity tests: `crates/freshell-sessions/tests/resume_resolve.rs` mirrors the matching-semantics subset of `test/integration/server/sessions-resolve-router.test.ts` plus shape-gate/budget coverage. DEFERRED (all remaining divergences, enumerated in the module docs of `resume_resolve.rs`/`resolve.rs` and tracked in `docs/plans/2026-07-30-rust-resolve-parity-hardened.md`): (1) matching semantics — the opencode by-id fallback still runs the RETIRED `resolveOpencodeSessionRoots` parent-walk instead of Node's hardened direct row query (`providers/opencode-by-id-query.ts`): orphaned/cyclic child rows miss where Node hits, a legacy-schema DB universally hits any full-shape `ses_*` id where Node hits only real rows, and hits omit Node's `title`/`lastActivityAt`; fallback hits hardcode `sessionType` `"claude"`/`"opencode"` instead of consulting the session-metadata overlay (Node's `sessionTypeFor`) — a freshclaude/freshopencode session resolved via fallback would resume under the wrong runtime; the claude fallback's `locate_transcript` never probes Node's `//subagents/.jsonl` layout, so subagent child transcripts miss; (2) response surface (plan Tasks 3, 5, 6) — `degraded` status, `providerErrors`, `unsearchedProviders`, `homeDir`, warming/ready readiness merge (the wired fallbacks map read errors to a MISS, never a provider error). Until ALL of that lands, the `sessionResolve` capability flag is rolled back to `false` (`build_platform_payload`, `main.rs`) and `test/e2e-browser/specs/resume-button.spec.ts` is removed from `MATRIX_SPECS` (chromium-only again).

Hardened parity was actually delivered by `1480e2a71` (hardened resolve wire: providerErrors/unsearchedProviders/homeDir, scan-failure merge, degraded refresh) and `22022a848` (capability + e2e matrix restore). CORRECTED IN-HISTORY (2026-07-31): both messages were reworded on this branch to accurately describe the retired legacy contract they implemented — now `e6e37c5d8` ("resume-resolve matching core for the retired pre-#586 legacy contract") and `fee2d2e3e` ("POST /api/sessions/resolve implementing the retired pre-#586 legacy contract"); the rewrite was message-only with identical trees.
