Keep alias assertions within the managed year range.
Both assertions accept aliases outside the 2026-2035 contract. They would accept a 2025 alias, which the production code deliberately reserves from the managed namespace, or a 2036 alias.

Assert legacy-first allocation.
The test only checks the assignment count and uniqueness. It passes if the allocator uses 2027-2035 aliases before all 365 legacy 2026 aliases are consumed.
Assert that exactly 365 assigned aliases are in 2026 and that the remaining alias is in 2027-2035. This protects the compatibility rule that existing allocation stays in the legacy ring until it is full.
As per path instructions, a behavior change in src/ requires a focused regression test in tests/.
Proposed test assertions

- expect(new Set(Object.values(profile.assignments).map(value => value.alias)).size).toBe(366);

Read the complete three-file diff at 426751f. Legacy-first allocation is the right compatibility boundary: existing 2026 hash/probe behavior is retained, and overflow starts only after that ring is exhausted. The actual capacity is 3652 slots; it remains bounded, not unlimited.
Please keep the original 2026-only assertions in the small-catalog tests instead of relaxing them to any 20xxxxxx date. Those fixtures do not exhaust the legacy ring, so their original assertions are useful protection for the compatibility promise you just restored. Add one persisted overflow-profile round trip through the Desktop alias resolver (including a valid leap date and an invalid-date negative control), rather than only counting 366 generated assignments. State what happens on downgrade: an older parser cannot load the newly persisted later-year aliases.
The current rollup establishes intake checks, not a completed exact-head full product suite. The older full-suite timeout is not a current green run. Keeping this as a candidate pending that caller/compatibility evidence and Jun's Desktop acceptance; no merge or local Desktop/config change.

39/39 on desktop-profile + desktop-3p, and TOTAL_ALIAS_SLOTS computes to 3652 — which is the right number: ten years with 2028 and 2032 leap, so 3650 + 2.
The claim I wanted to test was byte-stability, and it is structural rather than incidental — which is the strong form. Three things hold it together, and it is worth naming them because a reader skimming the diff sees "regex widened" and has to wonder:
legacyDayAlias(i)isformatSlotDate(2026, i + 1), character-for-character the olddayOfYearAlias;routeStartDaystill hashes toreadUInt32BE(0) % 365, so a given route begins probing at the same slot it always did;- the legacy ring is probed for all 365 offsets before overflow is reached, so a profile that fit in 2026 can never be pushed into 2027+.
Using readUInt32BE(4) for the overflow start rather than reusing bytes 0-3 is a nice touch — the two rings get independent probe orders out of one hash, instead of correlated collisions.
The widened regex does not weaken date validation. 202[6-9]\d{4}|203[0-5]\d{4} accepts impossible dates on its face, so I checked validDateAlias directly rather than reason about it:
reject ...-20261345 (month 13)
reject ...-20260229 (2026 is not a leap year)
accept ...-20280229 (2028 is)
accept ...-20320229
reject ...-20250101 (before the managed range)
reject ...-20360101 (after it)
accept ...-20351231
The regex is a pre-filter; the Date.UTC round-trip is the real validator and it was already there. Worth stating in the PR body, because "widen the year regex" is exactly the change where someone reasonably worries that 20261345 slipped through.
Keeping years before 2026 rejected — with the comment explaining that claude-opus-4-8-20250201 is a real snapshot id the inbound decoder distinguishes by that very property — is the detail I would have most expected a capacity fix to miss.
One question, not a blocker
overflowSlotAlias wraps with ((slotIndex % N) + N) % N, but its only caller derives the index from readUInt32BE(4) % N, which is already non-negative. Is the negative branch reachable, or is it belt-and-braces? If the latter it is fine and cheap; I only mention it because an unreachable guard in an allocator is the kind of thing that later gets read as evidence that negative indices are expected somewhere.
LGTM.

…ias range Two review findings on this lane were accurate. They are fixed on top of the lane rather than by rewriting a member's commit, so every member's ancestry and authorship stay intact. structure/providers/kiro.md said reasoningContentEvent carries the encrypted blob and "never text". The round-trip test #4682 added shows otherwise: every captured GPT-5.6 frame leaves a literal "..." placeholder on text and the adapter forwards it as a reasoning_raw_delta (tests/providers/kiro/kiro-reasoning-roundtrip.test.ts, "a signature blob is tagged with the field it must be replayed on"). The field is present; what it never carries is model reasoning. The wording now says that, which keeps the doc from contradicting its own binding test. #4224 widened the managed Desktop date aliases from 2026 alone (365 slots) to 2026-2035 (3652), but every user-facing description of that namespace still said claude-opus-4-8-2026MMDD: the ocx claude help text, the Claude Code guide in four locales, and structure/clients/claude-desktop.md did not mention the range at all. A user reading any of them would conclude a 2027 alias is not one of ours. All four surfaces now give the real range and record that 2026 is allocated first, so existing assignments keep their ids. No runtime behaviour changes here. The only src/ edit is the help string in src/cli/registry.ts.
